Abstract
The utility model discloses a soundless retainer for a deep groove ball bearing, which comprises a plurality of ball pockets. A main body on the inner side surface of each ball pocket is sphere; a spherical oil groove is arranged at the middle part of the sphere of the main body of each ball pocket; and the semi-diameter of the oil groove is smaller than that of the sphere of the main body of the ball pocket. According to the soundless retainer for the deep groove ball bearing, the oil groove is arranged inside each ball pocket; when a ball is placed in the ball pocket of the retainer, the ball is only locally contacted with each ball pocket; therefore, the storage space between the ball and the ball pocket is relatively larger, the rolling friction of the ball is reduced, and the noise is reduced.
Description
Technical field
The utility model relates to a kind of retainer, particularly a kind of quiet deep groove ball bearing retainer.
Background technique
At present, quiet deep groove ball bearing is widely used in every field such as machinery, traffic, household electrical appliances, and purposes is very extensive, and retainer is the critical component whether bearing can reach quiet level.The quiet deep groove ball bearing retainer ball pocket and the ball that exist are at present fitted fully, and the lubricant oil that stores between retainer ball pocket and the ball is few, and retainer and ball frictional force are big, and noise is big.
Summary of the invention
The problem that the utility model will solve is: a kind of quiet deep groove ball bearing retainer is provided, it is installed on the bearing, can effectively reduce the bearing noise.
For addressing the above problem, the utility model comprises a plurality of ball pockets, and the main body of described ball pocket inner side surface is a spherical, and the middle part of the main body spherical of ball pocket is provided with the oil groove of spherical, and the radius of oil groove is less than the radius of ball pocket main body spherical.
In order further to reduce noise, the main body spherical of described ball pocket is connected for the arc surface transition with the oil groove spherical.
The beneficial effect of the utility model: be provided with oil groove in the utility model ball pocket; When ball was placed in the ball pocket of retainer, ball had only the part to contact with the ball pocket, has the storage area of more lubricant oil between ball and the ball pocket; Reduce the frictional force that ball rolls, reduced noise.

Fig. 2 is the profile of part 1 among Fig. 1;
Fig. 3 is the profile of the ball pocket of the utility model user mode;
Among the figure: 1, ball pocket, 2, attachment hole, 3, oil groove, 4, ball.
Embodiment
Like Fig. 1, Fig. 2 and a kind of specific embodiment shown in Figure 3, it comprises a plurality of ball pockets 1, and the main body of ball pocket 1 inner side surface is a spherical, and the middle part of main body spherical is provided with the oil groove 3 of spherical, and the radius of oil groove 3 is less than the radius of the main body spherical of ball pocket 1.The main body spherical of ball pocket 1 can be that the arc surface transition is connected with the oil groove spherical.Be provided with attachment hole 2 between the adjacent ball pocket 1.
Method for using: this quiet deep groove ball bearing retainer uses in pairs; During use; In the ball pocket 1 of a quiet deep groove ball bearing retainer, put into ball 4; Another quiet deep groove ball bearing retainer is buckled, and the ball pocket 1 of two quiet deep groove ball bearing retainers is corresponding one by one, attachment hole 2 is corresponding one by one.In attachment hole 2, inserting link links into an integrated entity two quiet deep groove ball bearing retainers.
Claims (2)
1. a quiet deep groove ball bearing retainer comprises a plurality of ball pockets, it is characterized in that: the main body of described ball pocket inner side surface is a spherical, and the middle part of the main body spherical of ball pocket is provided with the oil groove of spherical, and the radius of oil groove is less than the radius of ball pocket main body spherical.
2. quiet deep groove ball bearing retainer according to claim 1 is characterized in that: the main body spherical of described ball pocket is connected for the arc surface transition with the oil groove spherical.
