Description

A kind of zirconia ceramics bearing ball

Technical field

The utility model relates to a kind of bearing ball, in particular to a kind of zirconia ceramics bearing ball.

Background technique

Bearing is a kind of important spare part in contemporary mechanical equipment, its major function is to support mechanical rotary body, is reduced Coefficient of friction in its motion process, and guarantee its rotating accuracy, bearing be generally outer ring, inner ring, bearing ball and connector into Row composition.

And current bearing ball generallys use steel ball, since the density of steel ball is higher, when running at high speed, centrifugal force is big, It causes to be rolled into load height, bearing is made to be relatively easy to be damaged, and under high grandson rotation, steel ball more generates higher temperature, To be relatively easy to that bearing is made segmentation crack occur, the service life of bearing ball greatly reduces, can not meet people's Demand.For this purpose, it is proposed that a kind of zirconia ceramics bearing ball.

Utility model content

The main purpose of the utility model is to provide a kind of zirconia ceramics bearing balls, can effectively solve background technique The problems in.

To achieve the above object, the technical solution that the utility model is taken are as follows:

A kind of zirconia ceramics bearing ball, including housing and shaft, the jacket internal is connected with shaft, described outer It is connected with connector between set and shaft, limit hole, the limit hole internal activity are fixed with inside the connector It is connected with bearing ball, the bearing ball is peripherally pivoted to be connected with limit plate, and the housing inner sidewall is fixed with No.1 rolling groove, No. two rolling grooves are fixed at the top of the shaft, are fixedly connected to graphite inside the No.1 rolling groove and No. two rolling grooves Ring.

Further, the connector two sidewalls are fixed with fixing groove, and the connector two sides are fixedly connected to Anti-skid cover.

Further, the bearing ball is located between No.1 rolling groove and No. two rolling grooves, and with No.1 rolling groove and two The rotation connection of number rolling groove, the housing are flexibly connected by bearing ball with shaft, the anti-skid cover pass through fixing groove with connect Part is fixedly connected.

Further, the housing, shaft and bearing ball make with zirconia ceramics, and the anti-skid cover is silicon rubber system The anti-skid cover of work.

Compared with prior art, the utility model has the following beneficial effects:

1. this kind is convenient for for a kind of zirconia ceramics bearing ball by the combination of No.1 rolling groove and No. two rolling grooves Bearing ball is placed between housing and shaft, consequently facilitating bearing ball is rotated, while can make bearing work, Middle housing, shaft and bearing ball are that zirconia ceramics is made, and have stronger high temperature resistant, low thermal coefficient of expansion and corrosion resistant The performances such as erosion, are not easy to be damaged, so as to greatly promote the service life of bearing ball.

There is good lubricant effect by graphite annulus, so as to reduce the friction between bearing ball and housing and shaft Power is avoided because frictional force is larger between housing and shaft, and influences the rotation of bearing ball.

It can will be attached between each bearing ball by connector, bearing ball is prevented to be in contact deviation in rotation Tracks avoid influencing bearing ball normal rotation, further promote the stability between bearing ball.

Specific embodiment

To be easy to understand the technical means, creative features, achievement of purpose, and effectiveness of the utility model, below In conjunction with specific embodiment, the utility model is further described.

As shown in Figs 1-4, a kind of zirconia ceramics bearing ball, including housing 1 and shaft 2,1 internal activity of housing connect It is connected to shaft 2, connector 3 is connected between the housing 1 and shaft 2, is fixed with limit hole inside the connector 3 4,4 internal activity of limit hole is connected with bearing ball 5, and the bearing ball 5 is peripherally pivoted to be connected with limit plate 6, the housing 1 Inner sidewall is fixed with No.1 rolling groove 7, and No. two rolling grooves 8,7 He of No.1 rolling groove are fixed at the top of the shaft 2 Graphite annulus 9 is fixedly connected to inside No. two rolling grooves 8.

Wherein, 3 two sidewalls of connector are fixed with fixing groove 10, and 3 two sides of connector are fixedly connected to Anti-skid cover 11.

Wherein, the bearing ball 5 is located between No.1 rolling groove 7 and No. two rolling grooves 8, and with No.1 rolling groove 7 and two Number rolling groove 8 is rotatablely connected, and the housing 1 is flexibly connected by bearing ball 5 with shaft 2, and the anti-skid cover 11 passes through fixing groove 10 are fixedly connected with connector 3.

Wherein, the housing 1, shaft 2 and bearing ball 5 make with zirconia ceramics, and the anti-skid cover 11 is silicon rubber The anti-skid cover of production.

It should be noted that the utility model is a kind of zirconia ceramics bearing ball, when work, pass through No.1 rolling groove 7 With the combination of No. two rolling grooves 8, convenient for bearing ball 5 to be placed between housing 1 and shaft 2, consequently facilitating 5 turns of bearing ball It is dynamic, while bearing can be made to work, wherein housing 1, shaft 2 and bearing ball 5 are that zirconia ceramics is made, and are had Stronger high temperature resistant, low thermal coefficient of expansion and the performances such as corrosion-resistant, are not easy to be damaged, so as to greatly promote bearing ball 5 service life has good lubrication secondly, being fixed with graphite annulus 9 inside No.1 rolling groove 7 and No. two rolling grooves 8 Effect avoids so as to reduce the frictional force between bearing ball 5 and housing 1 and shaft 2 because rubbing between housing 1 and shaft 2 Power is larger, and influences the rotation of bearing ball 5, secondly, can will be attached between each bearing ball 5 by connector 3, prevents Only bearing ball 5 was in contact bias motion track in rotation, avoids influencing 5 normal rotation of bearing ball, further promotes axis The stability between ball 5 is held, by the combination of limit hole 4 and limit plate 6, can effectively avoid bearing ball 5 from being turned It is detached from inside No.1 rolling groove 7 or No. two rolling grooves 8 when dynamic, to avoid damaging bearing, further bearing is carried out Protection, while can effectively prevent the substances such as dust from carrying out Bearing inner by anti-skid cover 11, to avoid influencing bearing The rotating effect of ball 5.
