Product details

Depending on the shape of the axis, shafts can be divided into two types: crankshaft and straight shaft. According to the bearing condition of the shaft, it can be divided into:

① Rotating shaft, which bears both bending moment and torque when working, is the most common shaft in machinery, such as the shaft in various reducers.

② Spindles are used to support rotating parts that only bear bending moments without transmitting torque. Some spindles rotate, such as the shafts of railway vehicles, while others do not rotate, such as the shafts that support pulleys.

③ Transmission shafts are mainly used to transmit torque without bearing bending moments, such as long optical shafts in crane moving mechanisms, and drive shafts in automobiles.
