CN203453265U - Novel crankshaft assembly in radial plunger motor - Google Patents

Abstract

The utility model discloses a novel crankshaft assembly in a radial plunger motor. The novel crankshaft assembly mainly comprises a crankshaft, a bearing sleeve and rollers, wherein the rollers are arranged on the crankshaft; a belleville spring presses the rollers and is fixed in the bearing sleeve by a clamp spring; the bearing sleeve is sleeved on the crankshaft; the rollers are separated by space rings. The novel crankshaft assembly disclosed by the utility model has the beneficial effects that mutual movement of the rollers of the space rings is prevented, the rotation speed and high-speed reliability of the crankshaft are improved, and the motor power is improved.

Description

New type crank assembly in a kind of radial plunger piston motor

Technical field

The utility model relates to the new type crank assembly in a kind of radial plunger piston motor.

Background technique

Crankshaft group in existing motor is comprised of bearing housing, bent axle and roller, and close-packed arrays between roller and roller is installed roller both inconvenient, and inevitable roller enters next door roller circle again, causes roller notes that rise, and causes bearing housing explosion in the time of seriously.

Summary of the invention

The purpose of this utility model is to overcome the deficiency that prior art exists, and the new type crank assembly in a kind of simple in structure, radial plunger piston motor that reliability is strong is provided.

The purpose of this utility model completes by following technical solution, and it mainly comprises bent axle, bearing housing and roller, and described row of rollers is listed on bent axle, and butterfly spring is pushed down roller and is fixed in bearing housing with jump ring, and described bearing housing is placed on bent axle.

As preferably, between described roller and roller, by spacer ring, separate.

The beneficial effects of the utility model are: prevent the mutual play of roller of next door circle, improve bent axle rotational velocity and high speed reliability, improve motor power.

Accompanying drawing explanation

Fig. 1 is structural representation of the present utility model.

Label in accompanying drawing is respectively: 1, bent axle; 2, jump ring; 3, roller; 4, bearing housing; 5, spacer ring; 6, belleville spring.

Embodiment

Below in conjunction with accompanying drawing, the utility model is done to detailed introduction: as shown in Figure 1, the utility model mainly comprises bent axle 1, bearing housing 4 and roller 3, described roller 3 is arranged on bent axle 1, and butterfly spring 6 is pushed down roller 3 use jump rings 2 and is fixed in bearing housing 4, prevents that axial roller from beating; Described bearing housing 4 is placed on bent axle 1; 3, described roller 3 and roller separate by spacer ring 5.

The utility model is not limited to above-mentioned mode of execution; no matter do any variation in its shape or material formation; every employing structural design provided by the utility model, is all a kind of distortion of the present utility model, all should think within the utility model protection domain.
