Description

The clino-axis type axial piston motor

Affiliated technical field:

The utility model relates to a kind ofly can convert hydraulic pressure to the oil hydraulic motor of mechanical energy, particularly a kind of clino-axis type axial piston motor.

Background technique:

Used output axle head is the clino-axis type axial piston motor of involute splines at present, a plurality of bearings in its housing, the axially locating circlip for hole of back-up ring and seal ring, and realize with adjusting the pad adjustment, seal section diameter near the transmission shaft of involute splines section is more a lot of greatly than the diameter of involute splines, the ball-and-socket that transmission shaft rear end and plunger ball link is directly processed on transmission shaft, the deficiency of this clino-axis type axial piston motor is, because of with circlip for hole with adjust the axially locating that the packing ring adjustment guarantees bearing etc., make the assembling trouble, the circlip for hole groove influences the intensity of bright body deeply simultaneously; Cause is more much bigger than the external diameter of involute splines near the seal section diameter of the transmission shaft of involute splines section, involute splines can only be processed with the gear shaping method, can not process with gear hobbing, and the working efficiency of gear shaping is more much lower than gear hobbing processing, big because of diameter simultaneously, linear velocity height during high speed rotating, and make the backbone sealing ring shortening in working life that is contained on its cylindrical; Because of the hardness of transmission shaft higher, the ball-and-socket that the bulb of transmission shaft rear end and plunger and central shaft links is directly processed in the difficult processing in the rear end of transmission shaft, inaccessible requirement such as surface roughness, and the bulb of plunger and central shaft and the frequent pivoting friction of this ball-and-socket make it fragile.

Summary of the invention:

Task of the present utility model is to overcome outside the deficiency of clino-axis type axial piston motor that present used output axle head is an involute splines, provide a kind of easy to assembly, involute splines both can be processed with the gear shaping method, also can process with generating process, the ball-and-socket of transmission oil rear end processes backsight at the ball-and-socket position of transmission shaft rear end clino-axis type axial piston motor with soft antifriction metal (AFM).

Task of the present utility model is achieved through the following technical solutions, the clino-axis type axial piston motor is by sealing seat, backbone sealing ring, a plurality of bearings, back-up ring, one end of axle is the transmission shaft (hereinafter to be referred as transmission shaft) of involute splines, housing, central shaft, cylinder body, plunger, oil distribution casing and pump cover are formed, a plurality of bearings and backbone sealing ring are contained on the transmission shaft, the cylindrical and the housing of a plurality of bearings link, one back-up ring is housed between the outer ring of bearing, the cylindrical and the housing of sealing seat link, the cylindrical of interior circle and backbone sealing ring links, plunger is contained in the plunger hole on the cylinder body, central shaft is contained in the center hole of cylinder body, one end of central shaft and the center hole of oil distribution casing link, the bulb end of plunger and the bulb end of central shaft ball-and-socket indivedual and the transmission shaft rear end links, the sphere position of oil distribution casing and the rear end of cylinder body link, its position, plane and pump cover link, and pump cover is contained on the housing with screw.Copper ball-and-socket liner is equipped with in the rear end of transmission shaft, the ball size of the size of this copper ball-and-socket and the bulb of central shaft, plunger matches, the diameter of this involute splines tool withdrawal groove of seal section diameter of the transmission shaft of next-door neighbour's involute splines section is slightly larger, and the front end of housing is with being with externally threaded bung flange to link with it sealing seat, a plurality of bearing and back-up ring axial restraint in housing.

The utility model and at present used output axle head are that the clino-axis type axial La Saimada of involute splines compares, have because of on the transmission shaft near the seal section reduced of involute splines section, thereby be convenient to the generating process processing of spline, can certainly Gear Shaping, make the adaptability of working machine tool strong, the manufacturing efficiency height; Because of the diameter of sealing section diminishes, its linear velocity is reduced, thereby the durability that is contained in the backbone sealing ring on its cylindrical is increased, prolonged working life, the transmission shaft rear end uses copper ball-and-socket liner to substitute the ball-and-socket of processing on the body of former transmission shaft rear end, promptly wear-resisting, be difficult for killing and burn out, be convenient to cutting again; The front end of housing is with being with externally threaded bung flange to link with it sealing seat, bearing, back-up ring axial restraint in housing, but the once mounting debugging put in place, saved the trouble that former adjustment pad is adjusted, assembling speed is accelerated.
