How Speed Reducers Basically Work?

November 6, 2020

Numerous motor and machine parts have been maximising the capabilities of speed reducers. Speed reducers are machine components that can reduce the speed of the motor and the machinery whenever power is transmitted. Additionally, speed reducers can duplicate the torque produced by a power source so they can expand the quantity of work. Without speed reducers, the components of a machine, especially its motor, may operate at an uncontrollable speed that may lead to unwanted damages.

Various Functions of Speed Reducers

As mentioned, speed reducers are intended to do two functions. The first function of speed reducers is to reduce and decelerate the speed of the motor as the power is being supplied. They do this so that the output of a motor, gears, and others will be set at a correct speed.

Another function of speed reducers is to take the torque from the power source or the input and multiply it accordingly. With this functionality, these components can easily yield torque inversely proportional to the deceleration, allowing them to expand and extend the permitted functional work.

Working Principles of Speed Reducers

So, how do speed reducers perform their various functions? The overall structure of speed reducers allows them to decrease the speed and increase the torque of a machine component. The output gear of speed reducers typically has more teeth than their input gear. The purpose of having more teeth on the output gear is to produce slower rotation movement, which will subsequently reduce the input speed and increase the total amount of torque or rotational force. 

As the speed reducers perform their intended functions, they will easily obtain torque that is proportional to the deceleration ratio. Cutting the rotational speed into half allows the speed reducers to double the amount of torque.

Most Basic Types of Speed Reducers

Speed reducers can have different shapes and sizes. They also come in a wide variety of types that are utilised in industries today. Some of the most basic types of speed reducers are the following:

  • Parallel Axis Gear Speed Reducer: This type of speed reducer typically works with a spur gear. Power with parallel axis gear speed reducer is carried out by rolling, allowing it to secure a transmission efficiency of around 98% per stage. 
  • Helical Speed Reducer: Helical speed reducer is somehow similar to the previous type. It is, however, uses helical gears that have twisted tooth trace. The presence of helical gears allows this type of speed reducer to transmit power smoothly and quietly.
  • Worm Speed Reducer: Aworm speed reducer is comprised of a worm gear and a worm wheel. The integration of these components allows this type of speed reducer to obtain a large deceleration ratio of about 1/10 to 1/60.
  • Bevel Gear Speed Reducer: This type of speed reducer is normally combined with a bevel gear, which can work effectively at an angle of 90°.
  • Hypoid Speed Reducer: Hypoid speed reducer has a gear that can offset the centre of a pinion gear axis. This composition allows it to add slip to the power transmission of spiral bevel gears, which can be similar to the way worm speed reducer works.
