The Purpose of Gearbox And its Functioning
Gears are used to transmit power from one part of a machine to another. To manipulate the magnitude of a force gears are used. You can have any number of gears connected together and they can be in different shapes and sizes. Gears use the principle of mechanical advantage, which is the ratio of output force to input force in a system. Mechanical advantage for gears, is given by the gear ratio, which is the ratio of the final gear’s speed to the initial gear’s speed in a gear train. The main purpose of gears is to increase speed or increase force.
An industrial gearbox is an enclosed system that transmits mechanical energy to a transmission unit. The system slows down the speed and torque of rotation. They are different from standard gearboxes, as the former needs a long, stable life and safety factor for most of the drives. An industrial gearbox transmits mechanical power into a driving tool to control speed and torque and convert it functionally. Gearboxes can handle multiple tasks at extremely high speeds for a long period.
An industrial gearbox helps mechanical operation in different industries. Helical gearboxes, coaxial helical lines, bevel helical gearboxes, skew bevel, and worm reduction gearboxes are the main gearboxes used in industries. Some of the industries in which industrial gearbox are used is in Paper Industry, Cement industry, Sugar industry. Steel industry, Refineries and more.
Being an integral part of the machinery, to ensure maximum efficiency routine maintenance should be carried out. Periodically testing gearboxes and assessing to fix potential faults helps to ensure this. The physical components of a gearbox may vary between its types and the variations between manufacturers. Most of the gearboxes are made up of iron, aluminium, or brass.
Spur gearboxes are also being produced using plastics as polycarbonates or nylons. Gear teeth orientation plays an important role in the overall device performance, torque, and speed. Simple gear teeth gearboxes are usually used for low-speed use. Helical gearboxes are used for high-speed applications usually as they are slower in operation it helps in improving the overall efficiency.
Worm Gearboxes are most commonly used for heavy-duty functions. This type of gear integrates a broad worm (or screw) diameter which meshes the teeth in the periphery of the gear. The device then makes it possible for the consumer to determine the rotation speed and for the transmission of higher torque.
Bevel Gears have curved teeth on cone-shaped surfaces near the unit bottom. They can be used to rotate non-parallel shafts and have a broad range of applications, including rolling stock and mining.
Helical gearboxes are large and utilize low power. When two teeth start to meet, the teeth of helical gears are shut down to an angle to the face of the machine, by one end of the tooth and remain in touch as the machine rotates completely into contact as the allows a smoother running and allows for high load angles.
Planetary gearboxes are common in advanced technologies, such as robotics and 3D printing. Three of four planet gears surround a planetary gearbox with a central Sun Gear and are held together via inner teeth outer ring equipment. This design similarly spreads power through the gears and makes it possible for a Planetary Gear System to achieve a high torque in a limited area. The two popular features of Planetary Gearboxes are its high endurance and precision
The technological advances and the development of gearboxes have resulted in the production of more efficient and powerful gearboxes (especially industrial gearbox) at a lower cost. Gearboxes are commonly used to monitor the direction of rotation and convert torque or power between inputs in applications that require a desired output speed. Gearboxes are used in many applications, including machine tools, construction machinery, transporters, and any device that needs modifications in the torque and speed of rotating movement power transmission.
Being used for speed and torque conversion gear reducers are an essential part of mechanical power transmission systems,. When selecting a gear reducer we have to know the required torque and speed as well as the most suitable type of motor to use. The most common benefits are that they can reduce speed, multiply torque, and solve inertia mismatching issues.
Speed reducers are mechanical devices generally used for two purposes. The primary use of a speed reducer is to multiply the amount of torque generated by an input power source so as to increase the amount of usable work. They also reduce the input power source speed to achieve desired output speeds.

What Are The Most Used Gear for Industrial Requirements???
Gears work on the principle of mechanical advantage. Different types of gears are used according to the industrial requirement. Gears are found in a wide range of industries like aeronautics, mining, manufacturing chains in the automotive sector, pharmaceutical industry, textiles, and more.
Basic operation of gears are based on the coupling between a crown and a pinion as sprockets and are manufactured with various materials with different tooth widths, face width, head circumference, and circular pitch. According to the position and shape of their teeth they are classified into parallel axis and nonparallel axis gears.
Parallel axis gears are Spur cylindrical gear, Helical cylindrical gears, and double helical gears or Herringbone gears.
Spur cylindrical gears generate radial reaction loads on the axis and transmit power through parallel shafts. The simplest of gear and it is usually used for small and medium speeds, because it generates noise as the speed increases.
In Helical cylindrical gears the power transfer occurs in the same way as in Spur gear but the axis can be parallel or nonparallel. The teeth in these gears are oblique in relation to the rotation axis and so they transmit more movement and at a higher speed. They are more silent, but require more lubrication and they wear more quickly.
Double helical gears or Herringbone gears combine the right and left helix. A symmetrical branch generates an opposite and equal thrust. They eliminate the axial thrust which means that bearings and supports no longer have to absorb it.
Nonparallel axis gears consists of Screw Gears, Spur, or Straight Bevel Gears, Spiral Bevel Gears, Hypoid Gears, Worm Wheels, and Worm Screws.
Screw Gears perform a wedge or screw movement resulting in a high degree of slip on the tooth flanks. They can move in the same direction or the opposite. Spur or Straight Bevel gears are not mush used today. By means of conical toothed surfaces they transmit the movement of axis that are cut in the same plane, usually in right angle. With axes positioned at 90 degrees they are often used to slow down and are noisy. The contact surface in a Spiral Bevel gears is larger compared to straight bevel gears. They can transmit the motion of axis that are cut and used to lower the speed on shafts of 90 degrees. In Hypoid gears their attack pinion is off-centre in relation to the axis of the crown. They have a long service life and low noise. They are usually used in boats and industrial machines. Worm Wheels have a worm screw, which functions as a conductor, and a crown, driven by it. The screw moves the crown with its turn.
There are some gears for special applications like Internal or Ring gears which are similar to Spur gears although their teeth are not ground on the outside, but on the inside of a wheel or rimmed ring. The inner gears are driven by pinion drives which maintains the direction of angular velocity. Planetary Gears also known as Epicyclic gears is a gear train in which a central gear has one or several external gears around it. They are commonly used for automobile transmissions. Rack and Pinion are used in lathes to move the longitudinal carriage; they do not have a transmission ratio, but a length ratio.
The different types of gears are used in many sectors like agricultural automotive naval vehicles, wind power, cement manufacturing industries, roller mills, and more.
Speed Reducer use circular and toothed gear pairs to lower the motor speed efficiently and safely. Gears with very different diameters to reduce the speed of rotation additionally.
They are generally used for two purposes; to multiply the amount of torque generated by an input power source to increase the amount of usable work and also to reduce the input power source speed to achieve desired output speeds.
There are different types of speed reducers depending on the classification and types of gearbox used for different purposes. Some of the types are planetary speed reducer, Spur and Helical, Worm and Bevel.

Gears Have Different Uses In a Wide Variety of Industrial and Mechanical Types of Equipment
Gears have different uses in a wide variety of industrial and mechanical equipment in addition to cars and bikes. Gears are used to control the power while a machine is being operated. The role of a gear in industrial machines is to optimize the productivity by reducing the speed and not the revolutions.
Industrial gear boxes are used in a variety of industries like Wind Power, Cement, Chemical, Rubber & Plastics, Construction, Food & Beverage, Marine, Material Handling, Metals & Mining, Power Generation, Recreational Vehicle, Transportation Industry, Agriculture, Automotive, Aerospace, Defence, Semiconductor, Robotics, Textile, and Healthcare to name a few. Industrial gearbox are mainly classified by their type like Planetary, Helical, Bevel, Spur, Worm and others like Helical-Bevel and Planetary Worm.
The most common type of industrial gears that are being used is Spur gears where the teeth of these gears fall parallel to a machine’s rotational axis. These type of gears are used in machines which have low speed applications and proper sound organization.
Helical type of gears are famous for their teeth-shaped edges which create a thrust load. Unlike Helical gears, the Spur gears are not parallel to a machine’s rotational axis. They are mainly used in industries like Rubber, Medical, Steel, Packing, and more.
Worm gears are used mainly in steel, sugar, paper, and textile plants. There are two types of worm gears, single-threaded and multi-threaded. They are also known as wheel industrial gears.
Bevel type of gears are used mainly for shafts where they are fitted at a right angle to a machine’s rotational axis. Some of the application where Bevel gears are used are in hand drill, printing, and a number of other machines.
Planetary gears are used in gearboxes that power everything from basic plant machinery to electric vehicles. Planetary gears are used in applications that demand high torque density, operational efficiency, and durability. When space and weight becomes an issue Planetary gears are often used where a large amount of speed reduction and torque are needed. Planetary gear are used in turbine engines, automatic transmissions, and even electric screwdrivers. They are also used in tractors and construction equipment.
Gear reducer are a mechanical transmission device that connects the motor to a driven load. They are also known as a gearbox. To modify the torque and speed between a motor and a load, Gear reducers are used. If your gearbox is down, you need keep it running as quickly and efficiently as possible. Repairing an existing gearbox can be the most quick and cost effective way. Procuring a new gearbox from manufacturers takes several months to get.

Gears are toothed, mechanical transmission elements used to transfer motion and power between machine components. Operating in mated pairs, gears mesh their teeth with the teeth of another corresponding gear or toothed component which prevents slippage during the transmission process. Each gear or toothed component is attached to a machine shaft or base component, therefore when the driving gear rotates along with its shaft component, the driven gear rotates or translates its shaft component. Depending on the design and construction of the gear pair, the transference of motion between the driving shaft and the driven shaft can result in a change of the direction of rotation or movement. Gears are available in a variety of designs, constructions, and configurations to suit a wide range of industries and applications.
There are many types of gears such as spur gears, helical gears, bevel gears, worm gears, gear rack, etc. These can be broadly classified by looking at the positions of axes such as parallel shafts, intersecting shafts and non-intersecting shafts. The most commonly used gears are
Spur Gear
Gears having cylindrical pitch surfaces are called cylindrical gears. Spur gears belong to the parallel shaft gear group and are cylindrical gears with a tooth line which is straight and parallel to the shaft. Spur gears are the most widely used gears that can achieve high accuracy with relatively easy production processes.
Helical Gear
Helical gears are used with parallel shafts similar to spur gears and are cylindrical gears with winding tooth lines. They have better teeth meshing than spur gears and have superior quietness and can transmit higher loads, making them suitable for high speed applications.
Bevel Gear
Bevel gears have a cone shaped appearance and are used to transmit force between two shafts which intersect at one point (intersecting shafts). A bevel gear has a cone as its pitch surface and its teeth are cut along the cone.
Screw Gear
Screw gears are a pair of same hand helical gears with the twist angle of 45° on non-parallel, non-intersecting shafts. Because the tooth contact is a point, their load carrying capacity is low and they are not suitable for large power transmission.
Worm Gear
A screw shape cut on a shaft is the worm, the mating gear is the worm wheel, and together on non-intersecting shafts is called a worm gear. Worms and worm wheels are not limited to cylindrical shapes. There is the hour-glass type which can increase the contact ratio, but production becomes more difficult.
A gear reducer is a mechanical transmission device that connects a motor to a driven load. It is also known as a gearbox. It allows you to modify the torque and speed between a motor and a load. Reduction gear assemblies are made up of series of gears. There are four main types of gear reducers: planetary gear reducers, worm gear reducers, gear train gear reducers and bevel gear reducers.

Leading Industrial Gear Reducer and Repair Company In USA
The term “gearbox” is used to refer to any piece of equipment connecting a motor and a machine that consists of a series of gears, otherwise known as a gear train. It receives the primary input speed from the motor and alters it to a different output speed using its gears. Different types and combinations of gears fulfil specific purposes. The types of gears found in gearboxes include spur, bevel, spiral, helical, and worm gears. The performance efficiency of a gearbox is indicated by its gearbox ratio which is the ratio of the input source rpm to the output source rpm.
Gear reducers are also known as speed reducers. The mechanical accessory that goes by either of these names is meant to reduce the rpm transmitted between a motor and the machinery it is powering. A speed reducer effectively decreases the speed produced by the motor to control the speed at which the machinery is operating and increases the torque produced by the motor. Speed reducer is expected to have a higher gearbox ratio, where the input source rpm is greater than the output source rpm. Multiplying the amount of torque generated by the motor increases the amount of usable power for the machine—this process is said to create a “mechanical advantage”. In greater context the gear reducer is basically a tool used to increase efficiency in facility operations.
Not all gearboxes, however, are speed reducers or gear reducers. There are other types of gearboxes that perform different functions. For example, another type of gearbox performs the opposite function of a speed reducer—it increases the speed produced by a motor and reduces torque.
We at American Gear with over 100 years of experience work with our clients to ensure their industrial gearboxes remain operational for the duration of their intended lifespan.
