Abstract

The utility model discloses a rotor assembly, including the rotor block, the equipartition has a plurality of calories of holes on the outer wall of rotor block, the roller subassembly is gone into to have by the card in the card hole, the roller subassembly includes that the one end card is gone into in the card hole and the other end has a storage tank plunger, shape and storage tank match and block in the storage tank is gone into to the oilless bearing of storage tank bottom and card just the roller body that contacts with oilless bearing, jump ring and lower jump ring are installed respectively to the upper end and the lower extreme of rotor block, it presses at roller body top to go up the bottom of jump ring, the bottom at the roller body is pressed at the top of jump ring down. The rotor assembly simple structure and the simple to operate that design from this.

Description

Rotor assembly

Technical field

This utility model relates to a kind of rotor assembly, is especially a kind of rotor assembly being installed in hydraulic motor.

Background technology

Hydraulic motor is a kind of executive component of hydraulic system, and it is defeated that the fluid pressure that hydraulic pump provides can be changed into it by it The mechanical energy of shaft.Rotor assembly is the important component part of hydraulic motor, and its structure generally comprises rotor block, outside rotor block Offering multiple installing hole on wall, installing hole is used for installing roller, and roller needs to position when mounted, and at present to roller Adopting the mode being screwed during location often, adopting the mode being screwed needs the thickness of rotor block sufficiently thick, and adopts The mode being screwed there is also the situation of stubborn bad screwed hole, cumbersome when structure is complicated and installs.

Utility model content

In view of the defect of above-mentioned prior art, the purpose of this utility model is: provide a kind of simple in construction and installation side Just rotor assembly.

Technical solution of the present utility model is: rotor assembly, including rotor block, uniform on the outer wall of described rotor block Having multiple hole clipping, snapped in roller assembly in described hole clipping, described roller assembly includes that one end snaps in hole clipping and other end tool Have the plunger of storage tank, shape and storage tank to match and be stuck in the oilless bearing bottom storage tank and snap in storage tank and with The roller body of oilless bearing contact；The top and bottom of described rotor block are separately installed with jump ring and lower circlip, described on The bottom of jump ring is pressed in roller bodies top, and the top of described lower circlip is pressed in the bottom of roller body.

Further, the outside of described oilless bearing has the arc surface of indent, this arc surface and the outer wall of roller body Contact and fit.

Further, the outer end of described storage tank is respectively provided on two sides with one for blocking the projection of roller body.

Further, the top and bottom of described rotor block are respectively equipped with draw-in groove and lower bayonet slot, described upper draw-in groove and under Draw-in groove snaps in for upper jump ring and lower circlip respectively.

Applying rotor assembly provided by the utility model, it provides the benefit that: the top and bottom of rotor block are pacified respectively Equipped with upper jump ring and lower circlip, the bottom of upper jump ring is pressed in roller bodies top, and the top of lower circlip is pressed in the end of roller body Portion, so just effectively can fix roller body by the setting of upper jump ring and lower circlip, it is not necessary to pass through screw Fixing mode, simple in construction and easy for installation.

Detailed description of the invention

For comparing intuitively, being fully understood by the technical solution of the utility model, now just combine this utility model accompanying drawing and carry out Nonrestrictive feature description is as follows:

As Figure 1-Figure 5, rotor assembly, including rotor block 1, the outer wall of rotor block 1 is evenly equipped with multiple hole clipping 2, card Having snapped in roller assembly 3 in hole 2, roller assembly 3 includes that one end snaps in hole clipping 2 and the other end has the plunger of storage tank 311 31, shape and storage tank 311 match and be stuck in the oilless bearing 32 bottom storage tank 311 and snap in storage tank 311 and with The roller body 33 of oilless bearing 32 contact；The top and bottom of rotor block 1 are separately installed with jump ring 4 and lower circlip 5, upper card The bottom of spring 4 is pressed in roller body 33 top, and the top of lower circlip 5 is pressed in the bottom of roller body 33.

The outside of oilless bearing 32 has the arc surface 321 of indent, this arc surface 321 and the wall contacts of roller body 33 And fit.The outer end of storage tank 311 is respectively provided on two sides with one for blocking the projection 6 of roller body 33.The setting of projection 6 be for Prevent the roller body 33 from skidding off from storage tank 311.

Installing jump ring 4 and lower circlip 5 for convenience, the top and bottom of rotor block 1 are respectively equipped with draw-in groove 7 and lower card Groove 8, upper draw-in groove 7 and lower bayonet slot 8 snap in for upper jump ring 4 and lower circlip 5 respectively.

Rotor assembly provided by the utility model, the top and bottom of rotor block 1 are separately installed with jump ring 4 and lower card Spring 5, the bottom of upper jump ring 4 is pressed in roller bodies top, and the top of lower circlip 5 is pressed in the bottom of roller body, so by upper Roller body 33 just can be fixed by the setting of jump ring 4 and lower circlip 5 effectively, it is not necessary to by the side that screw is fixing Formula, simple in construction and easy for installation.

Certainly, these are only preferred embodiment of the present utility model, non-the most i.e. limit to patent of the present utility model Scope, all utilization this utility model description and graphic content institute are simple for it modifies and equivalent structure change, all should in like manner wrap Within being contained in scope of patent protection of the present utility model.
