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
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 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 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 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.
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.

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. We ensure that every unit we refurbish and repair leaves our facilities in near-new condition. If we notice potential causes of failure during the repair stage, we notify the clients immediately. The result being that many of our industrial gearboxes perform better once they are returned and are less prone to damage or further problems.
We overhaul and rebuild any gearbox – even when existing gears and other components in your gear box are damaged beyond repair. What’s more we offer you the option of using either OEM replacements when available; or custom machined or fabricated parts to minimize downtime and get your gearbox back to duty promptly. Having experience with most OEM brands and designs of gearboxes and reducers we manufacture our own quality replacement gearing and components in-house to enhance performance and durability.
We service, overhaul, and supply spares or complete replacement industrial and mining gearbox including Falk, Amarilo, Marley, Philadelphia, Lufkin, Rexnord, Simens, Spx and many more…
