Network optimization information:

The starting mechanical efficiency is Hydraulic motor Indicators of starting performance. Under the same pressure, the output torque of the hydraulic motor from standstill to start rotation during startup is greater than the torque during operation, 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 can just reflect 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, Hydraulic synchronous motor Basically, it becomes dry friction, which leads to the reduction of starting torque, External five-star hydraulic motor The starting torque decreases. 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.

The working principle of cycloidal motor is similar to that of internal gear motor. The cycloidal motor adopts the cycloidal pin gear meshing gear instead of the internal meshing gear.
