4 Key Internal Components And Working Of Parallel Shaft Gear Reducers

4 Key Internal Components And Working Of Parallel Shaft Gear Reducers

The 4 key internal components of parallel shaft gear reducers include the input shaft, gear train, output shaft and bearing/seals. Bauer GMC, a major distributor of gear reducers, gear motors and electric gear motors in Mississauga, Ontario, explores these 4 key components and the working of parallel shaft gear reducers in this blog.

 

What Are The Main Internal Components Of Parallel Shaft Gear Reducers?

Input Shaft

The input shaft is the first part of the parallel shaft gear reducer. The main role of the input shaft is to receive power from the motor.

 

Gear Train

The main purpose of the gear train is to multiply torque within the gearbox. The gear train mainly comprises helical and spur gears for this function.

 

Output Shaft

After the torque multiplication, the output shaft transmits a high torque output and reduced speed to the required destination. 

 

Bearing/Seals

While the torque is created and transmitted to the output shaft, the bearings and seals present in the gear reducer are designed to maintain alignment. They are also designed to reduce wear and tear in the parallel shaft gear reducer.

 

How Does A Parallel Shaft Gear Reducer Work?

As the name suggests, this type of gear reducer has gears arranged on shafts that are oriented parallel to each other. This configuration transfers the power from the motor to the driven equipment by meshing the spur or helical gears in the gear train. The type of gear used depends on the design of the gear reducer.

 

Conclusion

In closing, parallel shaft gear reducers have an input shaft, gear train, output shaft and bearing/seals as their main components that transfer power from the motor to the driven equipment.
