Abstract:

The concept of the simulation startup process with micro gliding states for the friction pairs of hydraulic motor was put forwards,the magnitude of theoretical instantaneous torque and the losses of friction
torque were also discussed,which affected startup performance of the hydraulic motor.For the 2SJMD-100 hydraulic motor the quantitative calculation formula,a new and simple experimental method and data with “locking elastic shaft” were given.

Key words: inner friction pair, instantaneous torque, starting torque, loss of frictional torque
