Abstract
The utility model discloses a kind of roller bearing, including inner ring, outer ring, retainer, on retainer between described inner ring and outer ring, roller is installed, first roller draw-in groove, the second roller draw-in groove are offered respectively on described inner ring, the inner ring between described first roller draw-in groove and the second roller draw-in groove offers the first groove.A kind of roller bearing described in the utility model, there is 2 contact lines or contact surface in it when making to roll between roller and inner ring by the setting of groove, thus improving the stability when rolling for the roller, reduce rollers wear degree, thus improving the service life of roller bearing.
Description
Technical field
This utility model is related to a kind of roller bearing.
Background technology
Roller bearing includes inner ring, outer ring, retainer and roller.Its roller of the roller bearing being used at present and inner ring it
Between only have 1 contact line or contact surface when rolling, also only 1 contact line or contact surface when rolling between roller and outer ring.1
The stability that contact line or contact surface do not only exist roller is poor, and roller easily weares and teares, thus shortening the use of roller bearing
Life-span.
Utility model content
The purpose of this utility model is to provide a kind of roller bearing, and it is made between roller and inner ring by the setting of groove
There is 2 contact lines or contact surface during rolling, thus improving the stability when rolling for the roller, reducing rollers wear degree, from
And improve the service life of roller bearing.
In order to achieve the above object, the technical solution of the utility model is：
A kind of roller bearing, including inner ring, outer ring, retainer, the retainer between described inner ring and outer ring is provided with
Roller, described inner ring offers the first roller draw-in groove, the second roller draw-in groove, described first roller draw-in groove and the second roller respectively
First groove is offered on the inner ring between draw-in groove.
Second groove is offered on described outer ring, and described roller both sides symmetrically offer the first groove, the second groove.
The first groove is offered on inner ring in the middle of between described first roller draw-in groove and the second roller draw-in groove.
First elastomer block is installed in described first roller draw-in groove, the second elasticity is installed in described second roller draw-in groove
Block.
Between described inner ring and outer ring, closure is installed, and there is gap between described closure and roller.
The beneficial effects of the utility model are：A kind of roller bearing, it is made between roller and inner ring by the setting of groove
There is 2 contact lines or contact surface during rolling, thus improving the stability when rolling for the roller, reducing rollers wear degree, from
And improve the service life of roller bearing.
Brief description
Fig. 1 is structural representation of the present utility model.
Specific embodiment
Embodiment 1
A kind of roller bearing as shown in Figure 1, including inner ring 1, outer ring 2, retainer 3, between described inner ring 1 and outer ring 2
Roller 11 is provided with retainer 3, described inner ring 1 offers the first roller draw-in groove 4, the second roller draw-in groove 5 respectively, described
The first groove 6 is offered on inner ring 1 in the middle of between one roller draw-in groove 4 and the second roller draw-in groove 5.
Second groove 7 is offered on described outer ring 2, and symmetrically to offer the first groove 6, second recessed for described roller 11 both sides
Groove 7.Line between first groove 6 and the second groove 7 is vertical with roller 11 longitudinal center line.So that roller 11 and inner ring 1
There is 2 contact lines or contact surface, roller 11 there is also 2 contact lines or contact surface when rolling with outer ring 2 during rolling.Due to rolling
There is 2 contact lines or contact surface when rolling with inner ring 1, outer ring 2 in son 11, thus moving down in axial direction when avoiding roller 11 to roll
Dynamic, thus improving the stability when rolling for the roller.
First elastomer block 8 is installed in described first roller draw-in groove 4, in described second roller draw-in groove 5, second bullet is installed
Property block 9.First elastomer block 8 and the second elastomer block 9 are made by politef, the setting of the first elastomer block 8 and the second elastomer block 9
Put the stability that can improve roller 11.
Between described inner ring 1 and outer ring 2, closure 10 is installed, and between described closure 10 and roller 11 between presence
Gap.
A kind of roller bearing of the present embodiment, it has 2 when making to roll between roller and inner ring by the setting of groove
Contact line or contact surface, thus improving the stability when rolling for the roller, reduce rollers wear degree, thus improving roller bearing
Service life.
