A hydromotor is intended for opening and closing of cargo hatchway of airplane of Ан-132 and is established in the unpressurized,, unheated compartment. The structure of the motor includes unregulated pumping knot of and knot of output shaft seal. The pumping knot of hydraulic motor consists of a block of cylinders with plungers, of shaft, of spool, of separator and an inclined washer. The shaft is mounted on two bearings and has slots for connection with a cylinder block and for transmitting torque to the shaft of the gearbox. The body has two openings under the connections for the supply and removal of the working fluid and one under the connection for the drainage to the drain line. Depending on the direction of rotation, the working fluid is fed through one window of the spool to the plungers. The resulting torque is transmitted to the shaft and, accordingly, to the reducer. The return stroke of the plungers is carried out under the action of the inclined washer. The hydraulic motor is operated in hydraulic systems with a working fluid Skydrol LD-4, or Skydrol 500B-4, or HyJet-IV-Aplus at an inlet pressure of 21 MPa (210 kgf/cm2). The rated speed of the output shaft is 2500 rpm, the maximum speed is 3025 rpm. The weight of the hydraulic motor without working fluid is not more than 2.5 kg5481 Product Description popup.authors Облогін Євген Веніамінович popup.nrat_date 2020-04-02 Close
