Abstract

A rotor assembly structure comprises a shaft, a bearing, a shaft sleeve, a clamp spring, a spring and a gasket, wherein the bearing is sleeved on the shaft; the shaft sleeve is sleeved outside the bearing; the clamp spring, the spring and the gasket are all arranged among the bearings and are all sleeved on the shaft; the spring is arranged between the gaskets; the inner ring of the shaft sleeve is respectively provided with a first groove and a second groove, and an O-shaped ring is embedded and connected in the first groove; the clamp spring is clamped in the second groove. Compared with the prior art, the O-shaped ring and the snap spring are additionally arranged in the shaft sleeve, the bearing is in clearance fit with the shaft, and the bearing is limited by the snap spring, so that the bearing is ensured not to axially float in the shaft sleeve; the O-shaped ring is pre-tightened on the bearing in the radial direction and plays a role in vibration reduction, so that the noise of the whole rotor assembly is reduced by about 10 dB.

Description

Rotor assembly structure

Technical Field

The utility model relates to a bearing equipment technical field specifically indicates a rotor subassembly structure.

Background

The bearing is an important part in the modern mechanical equipment, the main function of the bearing is to support a mechanical rotator, reduce the friction coefficient in the movement process of the mechanical rotator and ensure the rotation precision of the mechanical rotator.

SUMMERY OF THE UTILITY MODEL

The to-be-solved technical problem of the utility model is to above-mentioned prior art not enough, and provide a rotor subassembly structure.

In order to solve the technical problem, the utility model discloses a technical scheme is:

a rotor assembly structure comprises a shaft, a bearing, a shaft sleeve, a clamp spring, a spring and a gasket, wherein the bearing is sleeved on the shaft; the shaft sleeve is sleeved outside the bearing; the clamp spring, the spring and the gasket are all arranged among the bearings and are all sleeved on the shaft; the spring is arranged between the gaskets; the inner ring of the shaft sleeve is respectively provided with a first groove and a second groove, and an O-shaped ring is embedded and connected in the first groove; the clamp spring is clamped in the second groove.

Furthermore, clearance fit is adopted between the bearing and the shaft.

Furthermore, "O" type circle sets up in the excircle outside of bearing, the bearing outside all is provided with two "O" type circles.

Further, the clamp spring is arranged between the left side bearing and the gasket.

Compared with the prior art, the O-shaped ring and the snap spring are additionally arranged in the shaft sleeve, the bearing is in clearance fit with the shaft, and the bearing is limited by the snap spring, so that the bearing is ensured not to axially float in the shaft sleeve; the O-shaped ring is pre-tightened on the bearing in the radial direction and plays a role in vibration reduction, so that the noise of the whole rotor assembly is reduced by about 10 dB.

Drawings

Fig. 1 is a schematic structural diagram of the present invention;

the bearing comprises a shaft 1, a shaft 2, a bearing 3, a shaft sleeve 4, a clamp spring 5, a spring 6, a gasket 7 and an O-shaped ring.

Detailed Description

The technical solution in the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present invention.

As shown in fig. 1, a rotor assembly structure comprises a shaft 1, a bearing 2, a shaft sleeve 3, a snap spring 4, a spring 5 and a gasket 6, wherein the bearing 2 is divided into two parts, the bearing 2 is sleeved on the shaft 1, and the bearing 2 and the shaft 1 are in clearance fit; the shaft sleeve 3 is sleeved outside the bearing 2, and the bearing 2 is positioned at two ends of the shaft sleeve 3; jump ring 4, spring 5 and gasket 6 all set up between bearing 2, and jump ring 4, spring 5 and gasket 6 all cup joint on axle 1.

Gaskets 6 are arranged on the inner sides of the bearings 2, and the springs 5 are arranged between the gaskets 6; the inner ring of the shaft sleeve 3 is respectively provided with a first groove and a second groove, and an O-shaped ring 7 is embedded and connected in the first groove; the clamp spring 4 is clamped in the second groove, the clamp spring 4 is arranged between the left bearing 2 and the gasket 6, the bearing 2 is limited by the clamp spring 4, and the bearing 2 is guaranteed to have no axial movement inside the shaft sleeve 3.

In this embodiment, "O" type circle 7 sets up in the excircle outside of bearing 2, the bearing 2 outside all is provided with two "O" type circles 7, "O" type circle 7 plays 2 radial pretensions to bearing, plays the damping effect simultaneously, when the high-speed rotation of rotor subassembly, can effective noise reduction.

The present invention is not limited to the above-described embodiments, and those skilled in the art can make modifications or changes without departing from the spirit of the present invention.
