Description

Fastening nylon retainer

Technical Field

The utility model belongs to the technical field of the holder, especially, lock joint formula nylon holder.

Background

Fig. 6 shows a nylon retainer commonly used in the prior art, which is simple in structure, convenient to manufacture, and widely applicable. However, because this kind of holder all adopts the structure of single holder body, and one side of pocket hole is provided with the opening, make one side of holder lighter than opposite side weight, consequently the bearing is at high-speed moving in-process, owing to receive must make the holder to incline heavy one side after centrifugal force's the influence, long-time use can lead to the holder pocket hole to take place to warp, the operation of steel ball in the holder can be unstable, cause the bearing vibration increase, lead to the noise increase, and make the bearing generate heat seriously, reduce life.

SUMMERY OF THE UTILITY MODEL

In order to overcome the defects of the prior art, the utility model provides a steel ball operates more steadily in the retainer, reduces the vibration of the bearing, and improves the service life of the bearing.

In order to realize the purpose, the utility model discloses a technical scheme is: the utility model provides a lock joint formula nylon holder, includes the holder body, it has a plurality of closed pocket holes to be along its circumference equipartition on the holder body, the holder body and the pocket hole is formed by first halfbody and second halfbody concatenation, just the pocket hole part on first halfbody and the second halfbody is the symmetry setting, be provided with a plurality of buckles that are used for playing fixed connection between first halfbody and the second halfbody, the buckle sets up between two adjacent pocket holes.

Adopt above-mentioned scheme, because the holder body is formed through first halfbody and the concatenation of second halfbody, and carry out fixed connection with first halfbody and second halfbody through the buckle, make it form the integration, can utilize first halfbody and second halfbody to balance the weight of holder body both sides, reduce the influence of centrifugal force to the holder, and cooperate closed pocket, make the steel ball can operate more steadily in closed pocket, and closed pocket compares among the prior art open-ended pocket and is difficult for taking place to warp, structural strength is better. The utility model discloses its simple structure, simple to operate can make the steel ball operate more steadily in the pocket is downthehole, reduces the bearing vibration, and the noise abatement improves the life of bearing.

As the utility model discloses a further setting, the buckle is including setting up connecting block on first half and the connector link of setting on the second half, the connecting block card is established in the connector link, the connector link be provided with the inlay groove of connecting block shape size adaptation, the notch department of inlay groove is provided with the barb that prevents the connecting block and deviate from.

By adopting the scheme, the connecting blocks are embedded in the embedded grooves of the connecting buckles to form quick connection, the installation efficiency is improved, the barbs on the connecting buckles can form positioning connection to prevent the connecting blocks from being separated, the buckling force can be increased to a certain degree, the first half body and the second half body are prevented from being disassembled, and the stability of high-speed operation of products is improved.

As a further setting of the utility model, the diapire of inlay groove is provided with the jack of through connection buckle, the position that corresponds the jack on the connecting block be provided with be used for with the fixed axle that inserts of jack grafting.

By adopting the scheme, the insertion shaft is in insertion fit with the insertion hole, so that the first half body and the second half body are in double fastening, the two retainers can be effectively prevented from sliding relatively, and the stability of integrated operation is further improved.

As the utility model discloses a further setting, it is provided with the anticreep piece that prevents to insert the axle and deviate from to insert the axial jack extension, be provided with the inclined plane that is convenient for insert the axle and insert the jack on the anticreep piece.

Adopt above-mentioned scheme, can further improve the intensity of pegging graft through the anticreep piece, prevent to insert the axle and deviate from, set up the inclined plane on the anticreep piece and can be convenient for insert the axle and insert the jack, improve the installation effectiveness.

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

Detailed Description

The utility model discloses a concrete embodiment is shown in fig. 1-5, a lock joint formula nylon holder, including holder body 1, holder body 1 adopts PA46 resin material to make, has high temperature resistance, and weight is also lighter, holder body 1 is last to have a plurality of closed pocket holes 2 that are along its circumference equipartition, holder body 1 and pocket hole 2 is formed by first halfbody 11 and the concatenation of second halfbody 12, just pocket hole 2 part on first halfbody 11 and the second halfbody 12 is the symmetry setting, be provided with a plurality of buckles 3 that are used for fixed connection between first halfbody 11 and the second halfbody 12, buckle 3 sets up between two adjacent pocket holes 2.

In the present embodiment, the buckle 3 includes a connection block 31 disposed on the first half body 11 and a connection buckle 32 disposed on the second half body 12, the connection block 31 is clamped in the connection buckle 32, the connection buckle 32 is provided with an embedded groove 321 adapted to the shape and size of the connection block 31, wherein the size of the embedded groove 321 can be slightly smaller than that of the connection block 31, the fit between the connection block 31 and the embedded groove 321 can form a small interference fit, the integration of the first half body 11 and the second half body 12 can be improved, the connection strength between the two half bodies can be enhanced, and a notch of the embedded groove 321 is provided with a barb 322 for preventing the connection block 31 from falling off.

In this embodiment, the bottom wall of the insertion groove 321 is provided with a hole 323 penetrating through the connection buckle 32, the connection block 31 is provided with an insertion shaft 311 corresponding to the hole 323 for being inserted into and fixed with the hole 323, and the outer diameter of the insertion shaft 311 can be slightly larger than the inner diameter of the hole 323, so that the connection between the insertion shaft 311 and the hole 323 forms a small interference fit, and the connection strength is further improved.
