Description

A kind of it is readily disassembled and bearing that frictional force is little

[technical field]

This utility model is related to mechanical field, particularly a kind of is readily disassembled and bearing that frictional force is little.

[background technology]

Bearing is a kind of important spare part in contemporary plant equipment.Its major function is supporting machinery rotary body, reduces Coefficient of friction in its motor process, and ensure its rotating accuracy.By the difference of motor element frictional property, bearing can be divided into rolling Dynamic bearing and sliding bearing two big class.In current rolling bearing, due to its retainer and rolling element direct friction, create relatively Big frictional force, further, since the outer ring of bearing and the integral design of inner ring, is not easy to bearing is dismantled, have impact on The service behaviour of bearing, shortens the service life of bearing.

[utility model content]

The purpose of this utility model is exactly to solve the problems of the prior art, proposes a kind of be readily disassembled and frictional force is little Bearing, can reduce bearing produced frictional force and very easily bearing being dismantled when rotating, be the guarantor of bearing Support and maintenance brings facility, improve the service behaviour of bearing, extend the service life of bearing.

For achieving the above object, the utility model proposes a kind of be readily disassembled and bearing that frictional force is little, including outer ring, Inner ring, bracing ring, rolling element, retainer, screwed hole and fixture, described outer ring is located at the outside of inner ring, and described bracing ring sets In the inner side of inner ring, the inner ring surface of described inner ring is fitted with the outer ring surface of bracing ring, the same side of described inner ring and bracing ring It is provided with some fixtures, inner ring is fixedly connected by described fixture with bracing ring, the inner ring surface of described outer ring is provided with and is available for rolling The slot rolling that body rolls, the outer ring surface of described inner ring is provided with the slot rolling being available for rolling element rolling, and described rolling element is located in slot rolling, institute State holding to be erected between rolling element.

Preferably, described inner ring includes the first half-turn and the second half-turn, corresponding on described first half-turn and the second half-turn It is provided with screwed hole, described screw thread in the hole is provided with drive screws and is fixedly connected the first half-turn and the second half-turn.

Preferably, described rolling element is small size bearing, described rolling element includes rolling outer shroud, spin and rolls inner prop.

Preferably, described retainer is connected with the axle center rolling inner prop.

The beneficial effects of the utility model: this utility model, by serving as the rolling element of bearing with small size bearing, keeps Frame is connected with the rolling inner prop of small size bearing, and inner ring is combined by the first half-turn and the second half-turn, is provided with inside inner ring Bracing ring, inner ring is fixedly connected with bracing ring by fixture, when bearing rotate when, can reduce frictional force and can facilitate right Bearing is dismantled, and compared with prior art, can reduce bearing produced frictional force and can be very easily right when rotating Bearing is dismantled, and is that the M R of bearing brings facility, improves the service behaviour of bearing, extends making of bearing Use the life-span.

Feature of the present utility model and advantage will combine accompanying drawing by embodiment and be described in detail.

[brief description]

Fig. 1 be this utility model a kind of be readily disassembled and bearing that frictional force is little structural representation.

In figure: 1- outer ring, 2- inner ring, 21- first half-turn, 22- second half-turn, 3, bracing ring, 4- rolling element, 41- roll Outer shroud, 42- spin, 43- roll inner prop, 5- retainer, 6- screwed hole, 7- fixture.

[specific embodiment]

Refering to Fig. 1, this utility model is a kind of be readily disassembled and frictional force bearing, including outer ring 1, inner ring 2, bracing ring 3, Rolling element 4, retainer 5, screwed hole 6 and fixture 7, described outer ring 1 is located at the outside of inner ring 2, and described bracing ring 3 is located at inner ring 2 inner side, the inner ring surface of described inner ring 2 is fitted with the outer ring surface of bracing ring 3, and described inner ring 2 is set with the same side of bracing ring 3 There are some fixtures 7, inner ring 2 is fixedly connected by described fixture 7 with bracing ring 3, the inner ring surface of described outer ring 1 is provided with and is available for rolling The slot rolling that kinetoplast 4 rolls, the outer ring surface of described inner ring 2 is provided with the slot rolling being available for rolling element 4 rolling, and described rolling element 4 is located at rolling In groove, described retainer 5 is located between rolling element 4, and described inner ring 2 includes the first half-turn 21 and the second half-turn 22, and described first Screwed hole 6 is correspondingly provided with half-turn 21 and the second half-turn 22, is provided with drive screws in described screwed hole 6 and by the first half-turn 21 and Two half-turns 22 are fixedly connected, and described rolling element 4 is small size bearing, and described rolling element 4 includes rolling outer shroud 41, spin 42 and rolls Inner prop 43, described retainer 5 is connected with the axle center rolling inner prop 43.

Utility model works process:

This utility model is a kind of be readily disassembled and bearing that frictional force is little in the course of the work, retainer 5 and rolling element 4 Roll inner prop 43 to be connected, when bearing is when rotating, the frictional force between retainer 5 and rolling inner prop 43, inner ring 2 can be avoided The drive screws being combined by the first half-turn 21 and the second half-turn 22 and passing through in screwed hole 6 are by the first half-turn 21 and the second half-turn 22 are fixedly connected, and the inner side of inner ring 2 is provided with bracing ring 3, and inner ring 2 is fixedly connected by fixture with bracing ring 3, when bearing needs During dismounting, by screwdriver, the drive screws in screwed hole 6 can be removed and then realize the fractionation to inner ring 2, with prior art Compare, bearing produced frictional force and very easily bearing being dismantled when rotating can be reduced, be the guarantor of bearing Support and maintenance brings facility, improve the service behaviour of bearing, extend the service life of bearing.

Above-described embodiment is to explanation of the present utility model, is not to restriction of the present utility model, any new to this practicality Scheme after type simple transformation belongs to protection domain of the present utility model.
