The rotating shaft, the axis of the heart and the drive shaft are commonly used in machinery, but their differences are also somewhat different.
The three axes of rotating shaft, mandrel and transmission shaft are fundamentally different from the original design. Each industry has great difference in application and bearing characteristics.
One, the axis of the heart
It is used to support the rotating parts only to bear the bending moment and not to transmit the torque. Some spindles are rotating, such as the axle of a railway vehicle, etc. Some spindles do not rotate, such as the shaft of the supporting pulley, etc.
The axis of the heart can be divided into a rotating axis and a fixed axis according to the rotation of the shaft at work.
Axis of rotation: when working, the shaft bears the bending moment, and the axis turns.
Fixed axis: when working, the shaft bears the bending moment, and the shaft is fixed.
Two. Drive shaft
It is a rotating body with high speed and less support, so its dynamic balance is very important. The general drive shaft should go into the balance test before leaving the factory and adjust it on the balance machine. For the front wheel engine driven vehicle, the transmission of the transmission is transmitted to the shaft of the main reducer. It can be in several sections. The joint between the nodes can be connected by universal joints.
Three. Rotating shaft
Rotating shaft: it is a shaft which is used to bear both bending moment and torque in rotating work. It is necessary to link the main parts of the zero part of the product.
The common axis is: mobile phone shaft (flip or rotary screen phone), notebook computer shaft, portable DVD shaft, LED lamp rotary shaft, LCD display shaft, GPS and other vehicle bracket rotating shaft and so on.
