End, is capable of achieving the linear motion system of unlimited stroke, is a kind of technology mode of low cost.
Bearing generally includes the retainer with opening, is arranged in retainer and protrudes the ball and ring with the opening
Around the housing that the retainer is set, sensitivity is obtained so that minimum frictional resistance is rolled into by ball high, high precision flat
Steady linear motion.But the retainer in correlation technique is made of plastic material, moulded in the prolonged rolling process of ball
Material retainer is easily accelerated its own to damage by frictional heating and the double action of abrasion, reduces the service life of retainer,
And the linear bearing sealing ring in correlation technique fixes insecure, sealing ring easily loosens, so that the poor reliability of bearing.
Therefore, it is necessary to provide a kind of new retainer and the linear bearing with retainer ask solving above-mentioned technology
Topic.

The raceway of shape support body and the connecting portion for being extended along the radial direction of the tubular support body by the tubular support body two ends respectively, institute
State tubular support body to be made up of metal material, the two ends of the tubular support body cooperatively form annular groove with the connecting portion respectively, institute
Stating retainer also includes being located at the lug boss and the groove with the spaced setting of the lug boss of the annular groove, the groove
Formed to connecting portion depression from the inwall of the annular groove.
Preferably, the tubular support body is made up of kirsite.
Preferably, the connecting portion is in plum blossom-shaped.
Preferably, the quantity of the groove is 1, and the quantity of the lug boss is 2, raised described in the groove and two
Portion's distribution triangular in shape.
Preferably, the quantity of the raceway is 6~8.
The utility model also provides a kind of linear bearing including above-mentioned retainer.
Compared with correlation technique, the retainer that the utility model is provided is made of zinc alloy material, compared to related skill
For plastic material in art, the stretching of the retainer, wear-resisting and high temperature resistance performance are enhanced, extend the retainer
Service life；By in the connecting portion, lug boss and groove are set, make to be contained in the sealing ring of the annular groove with it is described
Tubular support body is fitted close；The linear bearing passes through to use the retainer, so that with excellent stretching, wear-resisting and anti-height
The performance of temperature, extends the service life of the linear bearing.
Brief description of the drawings
Fig. 1 is the stereogram of the utility model retainer；
Fig. 2 is the stereogram of the utility model linear bearing.
Specific embodiment
Below in conjunction with drawings and embodiments, the utility model is described in further detail.
Fig. 1 is referred to, is the stereogram of the utility model retainer.The retainer 100 includes tubular support body 1, multiple
It is arranged at intervals at the tubular support body 1 and runs through the raceway 3 of the tubular support body and from the two ends of tubular support body 1 along the cylinder
The connecting portion 5 that the radial direction of shape support body 1 extends.
The tubular support body 1 has preset thickness, and the tubular support body 1 is made up of metal material, specifically, the tubular
Support body 1 is made up of kirsite, by using kirsite improve the retainer 100 stretch, wear-resisting and high temperature resistance performance.When
The right tubular support body 1 can also be made up of the metal material of other Wear-resistant, high-temperature resistants.
The raceway 3 is distributed along the axial direction of the tubular support body 1, and close-packed arrays are provided with multiple rollings in the raceway 3
Part (not shown), specifically, the rolling member is ball.In present embodiment, the quantity of the raceway 3 is 6~8.It is described
Raceway 3 is connected with the tubular support body 1, and the raceway 3 A/F less than the ball diameter, in the ball
While rolling can be contacted with the external world, prevent the ball from departing from the raceway 3.The raceway 3 in being U-shaped, distinguish by its two ends
Connect the tubular support body 1.
The connecting portion 5 is formed by the two ends of tubular support body 1 along the radial direction extension of the tubular support body 1.It is described
Connecting portion 5 is in plum blossom-shaped.The two ends of the tubular support body 1 form annular groove 61, i.e., described tubular frame with the connecting portion 5 respectively
The two ends of body 1 form difference in height with the connecting portion 5 respectively, so as to form a step.The annular groove 61 is used to house and it
The sealing ring (not shown) of mating connection, makes connection even closer firmly.
The retainer 100 also include located at the annular groove 61 lug boss 7 and spaced with the lug boss 7 set
The groove 8 put, the groove 8 is formed from the inwall of the annular groove 61 to the depression of the connecting portion 5.Specifically, the connection
