Analyze and clear common faults of roller bearing hydraulic motor:


(1) Output torque is not enough


(1) hydraulic motor: the inner hole of the roller and the shell hole are too loose, or the safety of the hydraulic five star motor is damaged after the oil inlet chamber of the working pressure oil leakage home oil chamber (oil chamber), the internal leakage expansion, then should be based on the brush plating or production processing roller plus.


(2) The blade root circle of the motor rotor is destroyed, and the internal leakage is large.


③ The waste will stick the blade and roller.


(4) hydraulic motor: roller and blade shaft inner hole due to machining accuracy and installation accuracy is not very good, so that the sliding friction of roller inner hole and blade root round inner hole is large, drift oil is cut, causing thousands of friction.


Can choose preventive measures for the above elements.


(2) Speed ratio is better than low speed and high torque hydraulic motor


The same as "output torque is not enough" elements ①, ②.


(2) The size of the transmission gear is damaged, so that the roller oil distribution accuracy is reduced, resulting in the oil in and out of the position of the string cavity.


③ The capacity of the gasoline pump is not enough.
