Network optimization information:

The starting mechanical efficiency is Hydraulic motor Indicators of starting performance. Because the conveyor belt is dedicated Cycloid hydraulic motor Under the same pressure, when starting, the output torque of the hydraulic motor from standstill to start rotation is greater than the torque when running, which makes it difficult for the hydraulic motor to start with load. Therefore, the starting performance is very important for the hydraulic motor, and the starting mechanical efficiency just reflects its starting performance.

The reason for the decrease of starting torque is that on the one hand, the static friction coefficient increases, and on the other hand, the static lubrication film of the hydraulic motor is squeezed out, Two speed motor Basically, it turns into dry friction, which leads to the reduction of starting torque. When the motor starts to run, the friction resistance will rapidly decrease with the establishment of the lubricating film, and will decrease with the increase of the thickness of the lubricating film and the sliding speed.

In fact, everyone hopes that the starting performance will be improved, that is, the starting torque and starting mechanical efficiency will be improved. Now, the starting mechanical efficiency of hydraulic motors with different structures has been roughly calculated numerically.
