Abstract

A split snap ring retaining ring, comprising an upper split retaining ring and a lower split retaining ring, the first through hole at one end of the upper split retaining ring passes through the first threaded hole at one end of the lower split retaining ring. One screw and the first washer are connected, the second through hole at the other end of the lower split retaining ring is connected with the second threaded hole at the other end of the upper split retaining ring with the second screw and the second washer, the upper split retaining ring, the lower The split retaining ring is installed in the groove on the shaft, a set of upper split retaining ring and lower split retaining ring are connected as a whole, and a set of upper split retaining ring and lower split retaining ring are respectively arranged on both sides of the part , when the part is subjected to axial load, the side of the part is tightly against the upper split retaining ring and the lower split retaining ring, and the upper split retaining ring and the lower split retaining ring are tightly against the groove of the shaft side, so the first screw and the second screw no longer bear the external load caused by the axial force, avoiding the deformation and fracture of the first screw and the second screw, so that the split snap ring retaining ring can bear large axial force force.

Description

A split snap ring retaining ring

technical field

The utility model relates to an axial positioning device for parts on a shaft, in particular to a split snap ring retaining ring.

Background technique

At present, the axial positioning of the existing parts on the shaft is guaranteed by the screw locking retaining ring, because the screw locking retaining ring can replace the shaft shoulder positioning, so it solves the problem that the parts on the shaft cannot be assembled due to too many shoulders problems, but also to save shaft material. When the parts on the shaft are subjected to axial force, the screws on the screw locking retaining ring are also subject to corresponding forces, but if the axial force on the parts on the shaft is too large, the screws are likely to deform and break, thus causing the screws The locking retaining ring cannot withstand large axial forces.

Contents of the invention

In order to overcome the above-mentioned shortcomings of the prior art, the purpose of this utility model is to provide a split snap ring retaining ring, which has a simple structure, can axially fix parts on the shaft, and can withstand large axial forces.

In order to achieve the above object, the technical solution of the utility model is achieved in that:

A split snap ring retaining ring, comprising an upper split retaining ring 1 and a lower split retaining ring 4, the upper split retaining ring 1 passes through the first through hole 2 at one end thereof and the first through hole 2 at one end of the lower split retaining ring 4 A threaded hole 3 is connected with the first screw 5 and the first washer 6, and the second through hole 9 at the other end of the lower split retaining ring 4 is connected with the second threaded hole 10 at the other end of the upper split retaining ring 1 with the second screw 11 , The second washer 12 is connected, and the upper split retaining ring 1 and the lower split retaining ring 4 are installed in the groove 8 on the shaft 7 .

The utility model has the advantages of simple structure, easy assembly, saving shaft material, being able to axially fix parts on the shaft, and capable of bearing large axial force.

Detailed ways

Below in conjunction with accompanying drawing, structural principle and working principle of the present utility model are described in detail.

Referring to Fig. 1, Fig. 2 and Fig. 3, a split snap ring retaining ring includes an upper split retaining ring 1 and a lower split retaining ring 4, and the upper split retaining ring 1 passes through the first through hole 2 at one end thereof The first threaded hole 3 at one end of the lower split retaining ring 4 is connected with the first screw 5 and the first washer 6, and the second through hole 9 at the other end of the lower split retaining ring 4 is connected with the other end of the upper split retaining ring 1. The second threaded hole 10 is connected with a second screw 11 and a second washer 12 , and the upper split retaining ring 1 and the lower split retaining ring 4 are installed in the groove 8 on the shaft 7 .

The working principle of the utility model is:

Referring to Figure 3, a set of upper split retaining ring 1 and lower split retaining ring 4 are connected as a whole, and a set of upper split retaining ring 1 and lower split retaining ring 4 are arranged on both sides of part 13 respectively, when part 13 When subjected to axial load, the side of the part 13 is tightly against the upper split retaining ring 1 and the lower split retaining ring 4, and the upper split retaining ring 1 and the lower split retaining ring 4 are tightly against the shaft 7 The side of the groove 8, so the first screw 5 and the second screw 11 no longer bear the external load caused by the axial force, avoiding the deformation and fracture of the first screw 5 and the second screw 11, so that the split snap ring The retaining ring can withstand large axial forces.
