Description
Technical field
The present invention relates to a kind of bearing ball, more particularly to a kind of zirconia ceramics bearing ball.
Background technology
Bearing is a kind of important spare part in contemporary mechanical equipment, its major function is the mechanical rotary body of support, is reduced
Friction coefficient in its motion process, and ensure its rotating accuracy, bearing be generally outer shroud, inner ring, bearing ball and connector into
Row composition.
And current bearing ball generally 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, makes bearing be relatively easy to be damaged, and in the case where high grandson rotates, 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.
Invention content
The main purpose of the present invention is to provide a kind of zirconia ceramics bearing balls, can effectively solve in background technology
Problem.
To achieve the above object, the technical solution that the present invention takes is：
A kind of zirconia ceramics bearing ball, including housing and shaft, the jacket internal are connected with shaft, the housing and
It is connected with connector between shaft, limit hole, the limit hole internal activity connection are fixed with inside the connector
There is bearing ball, the bearing ball is peripherally pivoted to be connected with limiting plate, and the housing madial wall is fixed with No.1 rolling groove, described
No. two rolling grooves are fixed at the top of shaft, graphite annulus has been fixedly connected with inside the No.1 rolling groove and No. two rolling grooves.
Further, the connector two side is fixed with fixing groove, and the connector both sides have been fixedly connected with
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 by 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 present invention has the advantages that：
1. this kind is used for a kind of zirconia ceramics bearing ball, by the combination of No.1 rolling groove and No. two rolling grooves, it is convenient for axis
Ball is held to be placed between housing and shaft, consequently facilitating bearing ball is rotated, while can make bearing work, China and foreign countries
Set, shaft and bearing ball are that zirconia ceramics is made, and have stronger high temperature resistant, low thermal coefficient of expansion and corrosion-resistant etc.
Performance is 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 implementation mode
To make the technical means, the creative features, the aims and the efficiencies achieved by the present invention be easy to understand, with reference to
Specific implementation mode, the present invention is further explained.
As shown in Figs 1-4, a kind of zirconia ceramics bearing ball, including housing 1 and shaft 2,1 internal activity of the housing connect
It is connected to shaft 2, connector 3 is connected between the housing 1 and shaft 2, limit hole is fixed with inside the connector 3
4,4 internal activity of the limit hole is connected with bearing ball 5, and the bearing ball 5 is peripherally pivoted to be connected with limiting plate 6, the housing 1
Madial wall is fixed with No.1 rolling groove 7, and 2 top of the shaft is fixed with No. two rolling grooves 8,7 He of No.1 rolling groove
It is fixedly connected with graphite annulus 9 inside No. two rolling grooves 8.
Wherein, 3 two side of the connector is fixed with fixing groove 10, and 3 both sides of the connector have been fixedly connected with
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 making.
It should be noted that the present invention is a kind of zirconia ceramics bearing ball, when work, pass through No.1 rolling groove 7 and two
The combination of number rolling groove 8, convenient for bearing ball 5 is placed between housing 1 and shaft 2, consequently facilitating bearing ball 5 is rotated,
Simultaneously bearing can be made to work, wherein housing 1, shaft 2 and bearing ball 5 are that zirconia ceramics is made, have compared with
Strong 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, secondly, be fixed with graphite annulus 9 inside No.1 rolling groove 7 and No. two rolling grooves 8, have good lubrication
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 limiting plate 6, can effectively avoid bearing ball 5 from being turned
