Summary of the invention
Technical problem to be solved by this invention is: a kind of Innercurve multiple-action radial plunger type hydraulic motor is provided, can effectively limit roller moving along self axis, and make, assemble simply, easily, can also prolong the working life of oil hydraulic motor, manufacturing efficiency height, practical.
The present invention addresses the above problem the technological scheme that is adopted: a kind of Innercurve multiple-action radial plunger type hydraulic motor, comprise cover plate, bonnet, stator, in the cavity that protecgulum forms, pintle is installed, the transmission shaft of band rolling bearing, be connected with roller in the epitrochanterian plunger hole, sliding bearing, plunger, also include circlip, described circlip uniform pawl type elbow circumferentially arranged, the two ends of described rotor outer surface are provided with groove, the both ends of the surface of described rotor are provided with and communicate with plunger hole and breach that quantity equates, described circlip is stuck in two grooves on the rotor outer surface, the both ends of the surface Spielpassung of roller in pawl type elbow on the described circlip and the plunger hole, roller is clipped in the middle of two pawl type elbows.
The quantity of the quantity of the breach on each end face of described rotor and circlip dewclaw type elbow is identical with the quantity of plunger hole.
Described circlip is the annulus that an opening is arranged, and the width of described pawl type elbow is less than or equal to the width of breach on the rotor end-face.
Compared with prior art, the invention has the advantages that: need not on each plunger hole, to process groove, can not influence the machining accuracy of plunger hole, circlip itself need not very high precision, can make by impact style, simplify difficulty of processing and cost greatly, improve manufacturing efficiency; Because of circlip is an overall structure, need not in each plunger hole, to install separately, as long as in epitrochanterian groove, snap in two circlips, just can play the effect that the roller in all plunger holes moves along axis that limits, thereby make roller stressed evenly, make the smooth working of hydraulic energy converting member energy, the mechanical efficiency and the reliability of oil hydraulic motor have been improved, prolonged simultaneously the working life of oil hydraulic motor again, in addition because of the flexible buffer function of pawl type elbow on the circlip, even roller is subjected to extraneous bump and vibrates, can not produce big destruction to circlip yet.
