Detailed Description

The utility model will be further described in detail with reference to the following examples, which are given in the accompanying drawings.

As shown with reference to figures 1-5,

a riveting type deep groove ball bearing plastic retainer comprises a steel plate 1 and a plastic assembly part 2 riveted on the steel plate 1; the steel plates 1 are at least two and are respectively positioned on two sides of the plastic assembly part 2, the steel plates 1 on two sides of the plastic assembly part 2 are riveted with the plastic assembly part 2 through rivets 3, and pockets 5 for assembling steel balls 4 are formed in the plastic assembly part 2.

Two steel sheet 1 are fastened in the two sides of a plastic assembly part 2 (namely, a plastic retainer) in a rivet 3 riveting mode, the steel sheet 1 can be fastened on the plastic assembly part 2, the circumferential strength of the plastic assembly part 2 is further improved, the plastic assembly part is prevented from being scattered, and the plastic assembly part 2 adopted by the plastic assembly part self is small in weight, so that the plastic assembly part is suitable for high-speed working conditions, the deficiency of strength is made up through the steel sheet 1, and the strength optimization and the weight optimization are achieved. Therefore, the scheme can provide a scheme for ensuring quality and effect under the working condition of high-speed operation. The mode of riveting by the rivet 3 can ensure that the assembly between the plastic assembly part 2 and the steel plate 1 is firmer and the installation efficiency is higher.

The following further provides a plurality of embodiments for the optimization of the above scheme, specifically as follows:

1. the quantity of pockets 5 on the plastic assembly part 2 corresponds with the quantity of steel balls 4, each plastic assembly part 2 corresponds to one steel ball 4, and the positions between two pockets 5 on the plastic assembly part 2 are all assembled with the steel plates 1 on two sides in a rivet 3 riveting mode.

2. The number of the plastic assembly parts 2 is a plurality, pockets 5 are arranged on one opposite sides of two adjacent plastic assembly parts 2, and the steel balls 4 are assembled on the two adjacent plastic assembly parts 2 through the pockets 5; and a plurality of plastic assembly parts 2 are assembled with the steel plates 1 on two sides in a riveting mode through rivets 3. A relatively rotatable connection between the plastic fitting 2 and the rivet 3.

3. The plastic fitting 2 is also injection molded onto the steel plate 1.

4. The plastic assembly 2 is also connected to the steel plate 1 by ultrasonic rivet welding.

In the above embodiment 1, the positions between the pockets 5 can be assembled by riveting with the rivets 3, and the support strength of the plastic assembly 2 can be reinforced by the rivets 3, which is equivalent to filling the plastic assembly 2 with metal supports to increase the strength by the metal supports. And the reinforcing effect of the steel plate 1 can eliminate the strength damage caused by the integral molding of the plastic assembly 2 by the drill hole. The strength of the plastic fitting 2 can be increased.

In the above embodiment 2, the plastic assembly parts 2 in the embodiment 1 are separated into a plurality of parts, the pockets 5 are formed on the opposite surfaces of the adjacent plastic assembly parts 2, a half pocket 5 is formed on the side surface of each plastic assembly part 2, a complete pocket 5 is formed between the two adjacent plastic assembly parts 2, and the steel ball 4 is assembled.

Can rotate between plastics assembly part 2 and the rivet 3, can realize automatic adjustment when the cooperation is assembled steel ball 4 between each plastics assembly part 2, pocket 5 can be according to current operating condition self-adjustment to the assembly effect of steel ball 4, simultaneously because rivet 3 assembles plastics assembly part 2, can let steel ball 4 be in an interval within range self-adaptation adjustment more stable.
