Gear hydraulic motor use precautions
(1) The installation between the output shaft of the gear hydraulic motor and the actuator is made of elastic coupling, greater than 0.1mm, the coaxiality error shall not be greater than 0.01mm, and the axial error of the sleeve-type coupling shall not exceed 0.05mm.
(2) The back pressure of the gear hydraulic motor drain port shall not exceed 0.05 MPa.
(3) Gear hydraulic motor working medium is recommended to use No. 46 hydraulic oil or other sports viscosity neutral mineral oil.
