Abstract
The utility model provides a cam bearing. Relates to a bearing, in particular to an improvement of a cam bearing. A cam bearing in which a roller does not play axially and radially is provided. The steel ball bearing comprises an outer ring and an inner ring, wherein a roller is arranged between the outer ring and the inner ring, a check ring is arranged on one side of the roller, a first steel ball is arranged between the check ring and the end face of the roller, a first limit groove is formed in the check ring, and the first steel ball is clamped in the first limit groove. The steel ball is arranged in the limiting groove, the steel ball is attached to the bottom of the limiting groove, so that the steel ball is in excessive fit with the roller, the steel ball and the bearing outer ring are in clearance fit, the steel ball cannot radially displace during working, the roller cannot radially displace in the axial direction, the noise of the bearing during operation is reduced, and the overall performance is improved.
Description
Technical Field
The utility model relates to a bearing especially relates to cam bearing's improvement.
Background
The cam bearing usually uses steel balls to limit the axial movement of the needle roller, namely, two ends of the needle roller are respectively provided with one steel ball, so that the steel balls and the end parts of the needle roller are kept in over-fit, the steel balls and the bearing outer ring are in clearance fit, the radial force is completely borne on the needle roller, and the needle roller cannot axially move due to the limit of the steel balls. However, the steel ball is in clearance fit with the bearing outer ring and is not controlled by radial positioning, so that radial play noise is generated after the steel ball works, and the effect of no noise caused by bearing rotation is not achieved.
SUMMERY OF THE UTILITY MODEL
In order to overcome the defects of the prior art, the utility model provides a cam bearing of axial and radial play can not appear in roller.
The utility model discloses a following technical scheme realizes: the cam bearing comprises an outer ring and an inner ring, wherein a roller is arranged between the outer ring and the inner ring, a check ring is arranged on one side of the roller, a first steel ball is arranged between the check ring and the end face of the roller, a first limit groove is formed in the check ring, and the first steel ball is clamped in the first limit groove.
One end of the first steel ball abuts against the end face of the retainer ring, and the first steel ball is clamped in the first limiting groove and rotates in the first limiting groove along with the rotation of the roller.
And a mandrel is arranged on the other side of the roller and inserted into the inner ring, a separation blade of the mandrel is attached to the end surface of the outer ring, and a second steel ball is arranged between the separation blade and the roller.
And the two ends of the outer ring are respectively provided with a clamping groove, and the check ring and the blocking piece are respectively arranged in the clamping grooves.
Compared with the prior art, the utility model discloses processing out concave arc shape with the separation blade of retaining ring and dabber and steel ball contact surface and forming the spacing groove, the limiting groove is arranged in to the steel ball, the tank bottom laminating steel ball of spacing groove has both guaranteed like this that the steel ball is excessive cooperation to the spacing of roller, guaranteed again that steel ball and bearing inner race are clearance fit, and the during operation steel ball can not take place radial displacement, make the roller at axial and the footpath all can not take place the displacement, thereby noise when reducing the bearing operation, promote the wholeness ability.
Drawings
FIG. 1 is a schematic structural view of the present invention;
FIG. 2 is an enlarged schematic view of the structure at A in FIG. 1;
in the figure: 1. an outer ring; 2. a roller; 3. a first steel ball; 4. a second steel ball; 5. a retainer ring; 6. a baffle plate; 7. a second limit groove.
Detailed Description
The present invention will be further described with reference to the accompanying drawings and the detailed description, and it should be noted that the embodiments or technical features described below can be arbitrarily combined to form a new embodiment without conflict.
As shown in fig. 1-2, the cam bearing includes an outer ring 1 and an inner ring, a roller is disposed between the outer ring 1 and the inner ring, a retainer ring 5 is disposed on one side of the roller, a first steel ball 3 is disposed between the retainer ring 5 and an end surface of the roller, a first limit groove is disposed on the retainer ring 5, and the first steel ball 3 is clamped in the first limit groove. The retaining piece 6 of retaining ring 5 and dabber and steel ball contact surface process out concave arc and form the spacing groove (first spacing groove, second spacing groove 7), the steel ball is arranged in the spacing groove, the tank bottom laminating steel ball of spacing groove, both guaranteed like this that the steel ball is excessive cooperation to roller 2, guaranteed again that steel ball and bearing inner race 1 are clearance fit, and the during operation steel ball can not take place radial displacement, make roller 2 all can not take place the displacement in axial and footpath, thereby reduce the noise when the bearing operates, promote the wholeness ability.
One end of the first steel ball 3 abuts against the end face of the retainer ring 5, and the first steel ball 3 is clamped in the first limiting groove and rotates in the first limiting groove along with the rotation of the roller 2. The other side of the roller is provided with a mandrel, the mandrel is inserted into the inner ring, a separation blade 6 of the mandrel is attached to the end surface of the outer ring 1, and a second steel ball 4 is arranged between the separation blade 6 and the roller 2. The retaining piece 6 of retaining ring 5 and dabber and steel ball contact surface processing go out concave arc and form the spacing groove, and the steel ball is arranged in the spacing groove, and the tank bottom laminating steel ball of spacing groove had both guaranteed like this that the steel ball is excessive cooperation to roller 2, had guaranteed again that steel ball and bearing inner race 1 are clearance fit, and the during operation steel ball can not take place radial displacement for roller 2 all can not take place the displacement in axial and footpath, thereby noise when reducing the bearing operation, promotion wholeness can.
The two ends of the outer ring 1 are respectively provided with a clamping groove, and the retainer ring 5 and the baffle 6 are respectively arranged in one clamping groove.
The above embodiments are only preferred embodiments of the present invention, and the protection scope of the present invention cannot be limited thereby, and any insubstantial changes and substitutions made by those skilled in the art based on the present invention are all within the protection scope of the present invention.
