Detailed Description

The present invention will be described in further detail with reference to the accompanying drawings.

Example (b): a bearing retainer, as shown in figure 1, comprises a base 1, a support column 2 and a clamping ring 3, wherein the support column 2 is vertically fixed on the base 1, the clamping ring 3 is connected to one end, far away from the base 1, of the support column 2, and the base 1 and the clamping ring 3 are coaxially arranged.

As shown in fig. 2, the snap ring 3 is connected with the support column 2 through the connection assembly 4, the connection assembly 4 includes a positioning groove 41 which is arranged at the support column 2 and far away from one end of the base 1, a trapezoidal groove 42 is further arranged at one side of the positioning groove 41 close to the axis of the base 1, a positioning block 43 which is correspondingly arranged on the snap ring 3 and is in splicing fit with the positioning groove 41, and a limit block 44 which is correspondingly arranged on the snap ring 3 and is in splicing fit with the trapezoidal groove 42, the positioning block 43 on the snap ring 3 is inserted into the positioning groove 41, and the limit block 44 is inserted into the trapezoidal groove 42.

As shown in fig. 2, pure insertion fit does not ensure the connection stability between the snap ring 3 and the support post 2, a protrusion 441 is disposed on one side of the limiting block 44 away from the center of the snap ring 3, and a limiting hole 421 is disposed on one side of the trapezoidal groove 42 away from the central axis of the snap ring 3; when the limiting block 44 is inserted into the trapezoidal groove 42, the protrusion 441 is clamped into the limiting hole 421 to achieve the limiting effect, and the connection stability between the clamping ring 3 and the supporting column 2 is improved.

As shown in fig. 2, in the process of detaching the snap ring 3, because the snap ring 3 and the support post 2 have certain deformation capacity, one side of the trapezoidal groove 42 close to the center of the snap ring 3 is set to be a structure penetrating through the support post 2, the limit block 44 can be inclined to the axis of the snap ring 3, and the limit block 44 and the trapezoidal groove 42 are deformed to a certain extent, so that the protrusion 441 can be quickly pulled out of the limit hole 421; meanwhile, in the installation process, the limiting block 44 is inserted into the trapezoidal groove 42 in a sliding mode, the trapezoidal groove 42 which is not completely sealed deforms, the limiting block 44 can be stably inserted into the trapezoidal groove, after the limiting block 44 and the protrusion 441 reach the installation position, the trapezoidal groove 42 recovers to a normal shape, the connection stability of the clamping ring 3 and the supporting column 2 is facilitated, the damage to the retainer in the installation and disassembly processes is reduced, and the service life of the retainer is prolonged.

As shown in fig. 1, because the retainer is used in the middle of the bearing to drive the balls to rotate, and the retainer is damaged and inconvenient to replace, a plurality of strip-shaped grooves 5 are arranged on the snap ring 3, the strip-shaped grooves 5 extend to the outer side of the edge of the snap ring 3, and the extending directions of two adjacent strip-shaped grooves 5 are opposite; through the arrangement of the two strip-shaped grooves 5 in different extension directions, the stress on the snap ring 3 in the actual use process can be dispersed, so that the inner side and the outer side of the snap ring 3 are prevented from being subjected to extrusion force, the retainer is prevented from being broken, and the service life of the retainer is prolonged; in addition, also can receive certain pulling force at the in-process that snap ring 3 dismantled, bar groove 5 can increase snap ring 3's deformation range to reduce the impaired condition of snap ring 3, improved snap ring 3's reuse rate.

As shown in fig. 1 and 3, in the use process of the retainer, friction is generated between the base 1, the snap ring 3 and the contact surface of the support pillar 2 and the ball, and in order to reduce the abrasion of the retainer in the working process, an oil storage hole 6 is arranged at the height center of the support pillar 2, the depth direction of the oil storage hole 6 penetrates through the support pillar 2, the opening direction of the oil storage hole 6 faces to the adjacent support pillar 2, an oil storage cover 7 which is detachably connected is arranged on the oil storage hole 6, and an oil outlet 8 is arranged on the oil storage cover 7; in actual use, the lubricating oil in the oil storage hole 6 flows out from the oil outlet hole 8, plays a role in lubricating the balls and the retainer, reduces friction damage between the balls and the retainer, and prolongs the service life of the retainer.

As shown in fig. 1, the oil storage cover 7 is circular arc-shaped, and the circular arc-shaped oil storage cover 7 can increase the contact area between the balls and the oil storage cover 7, thereby being beneficial to the stability of the balls on the retainer and reducing the situation that the balls fall off from the retainer.

As shown in fig. 1, be equipped with the gasket 11 of a plurality of circular arcs on base 1, gasket 11 sets up between two adjacent support columns 2, and the ball in the middle of the holder is contradicted with gasket 11 on the base 1, and gasket 11 can play the guard action to base 1 to alleviate the ball and rotate the wearing and tearing to the base, simultaneously, also increase the area of contact of ball and base 1, be favorable to the stability of ball on the holder, reduce the condition that the ball drops from the holder.

As shown in FIG. 1, because the friction heat generation phenomenon occurs during the rotation of the balls, and the deformation of the retainer is easily caused by the temperature rise, the heat dissipation holes 9 are formed in the gasket 11, the depth of the heat dissipation holes 9 penetrates through the base 1, and the heat generated by friction can be dispersed through the heat dissipation holes 9, thereby preventing the deformation of the retainer caused by the friction heat generation.

As shown in fig. 1, an arc-shaped groove 31 is formed in one side of the snap ring 3 close to the base 1, and when balls are arranged between the snap ring 3 and the base 1, the balls are attached to the arc-shaped groove 31, and due to the arc-shaped structure on the surface of the arc-shaped groove 31, abrasion between the balls and the snap ring 3 can be reduced, so that the service life of the retainer is prolonged; meanwhile, the contact area of the balls and the snap ring 3 is increased, the stability of the balls on the retainer is facilitated, and the situation that the balls fall off from the retainer is reduced.

The specific implementation process comprises the following steps: at first at the interior lubricating oil that stores of oil storage hole 6, then cover oil storage lid 7, arrange the ball in and contradict with gasket 11 on the base 1, later insert locating piece 43 on the snap ring 3 in the constant head tank 41, stopper 44 on the snap ring 3 is pegged graft in dovetail groove 42 simultaneously, protruding 441 card is in spacing hole 421, thereby make snap ring 3 link together with support column 2, fix the ball in the middle of the holder, lubricating oil flows out from oil outlet 8 in the course of the work and can play the lubrication action to ball and holder, alleviate the wearing and tearing of holder, the life of extension holder.

The present embodiment is only for explaining the present invention, and it is not limited to the present invention, and those skilled in the art can make modifications to the present embodiment without inventive contribution as required after reading the present specification, but all of them are protected by patent laws within the scope of the claims of the present invention.
