Description

Technical Field

[0001] The present application relates to the technical field of bearings, and in particular to a retaining rack. Background Art

[0002] Rolling bearings are common components in mechanical equipment, used to reduce friction between rotating shafts and supports, and to withstand radial and axial loads. Rolling elements (such as balls or rollers) roll between inner and outer rings to reduce friction and support rotation. Cages, as an important component of bearings, play a vital role in ensuring the performance and life of bearings.

[0003] The main function of the cage is to partially enclose the rolling elements and move with them in the bearing to isolate the rolling elements and prevent them from interfering with each other. It is also usually responsible for guiding the rolling elements. The design of the cage directly affects the operating efficiency, reliability and service life of the bearing. In high-speed, high-precision or high-load applications, the structural strength and lightness of the cage are particularly important.

[0004] However, existing cage designs often face challenges in material selection and manufacturing processes while achieving structural reinforcement. In order to achieve the required strength and lightweight goals, high-strength materials may need to be used, which will increase costs and may have adverse effects on the environment. In addition, the use of high-strength materials may also increase the brittleness of the cage and reduce its reliability. Therefore, developing a cage design that has both excellent structural strength and lightweight is a long-standing technical challenge facing the bearing industry.

[0005] On the other hand, the cage needs to consider its cost-effectiveness while ensuring the normal operation of the bearing. In today's fiercely competitive market, reducing costs, improving production efficiency, and ensuring product quality are issues that bearing manufacturers are extremely concerned about. Therefore, how to optimize the cage design to achieve the balance between cost and performance as much as possible is also a direction that the bearing industry continues to explore. Utility Model Content

[0006] In order to achieve a balance between cost and performance as much as possible, the present application provides a retaining frame.

[0007] The present application provides a retaining frame, which adopts the following technical solution:

[0008] A retaining frame includes a frame body, a pocket is arranged on the frame body, the frame body includes a base, and a pocket portion with a thickness less than the base, the pocket portion includes a connecting portion and an arc-shaped locking rib, the locking rib and the connecting portion are both connected to the base, the pocket is formed between two adjacent relatively bent locking ribs, the pocket portion is located on the base, and the connecting portion connects the two locking ribs between the two adjacent pockets.

[0009] By adopting the above technical solution, a thicker base is provided to provide good structural strength, and the thickness and axial width of the base can be set according to the requirements of strength and lightness. At the same time, the locking ribs are connected by setting the connecting part, thereby improving the structural strength of a single locking rib. At the same time, since the pocket part is located on the base, it can play a better structural strength when the pocket part is thin, thereby achieving a further balance between cost and performance.

[0010] In one embodiment, a lightweight cavity is provided on the inner side of the base.

[0011] By adopting the above technical solution, the base is relatively thick, and the arrangement of multiple lightweight cavities has little effect on its structural strength, but further lightweighting can be achieved.

[0012] In one embodiment, one end of the lightweight cavity axially penetrates the end of the base, and the other end extends to the connecting portion.

[0013] By adopting the above technical solution, the through-setting is convenient for production and processing on the one hand, and can make the lightweight cavity longer on the other hand.

[0014] In one embodiment, the lightweight cavity extends to an end of the connecting portion and is arranged in an inclined surface.

[0015] By adopting the above technical solution, when the length of the lightweight cavity is too large, it is easy to affect the structural strength of the connection part. Therefore, by setting the inclined surface, the influence on the structural strength of the connection part can be reduced while increasing the length of the lightweight cavity.

[0016] In one of the embodiments: a weight-reducing groove is provided on the outer side of the connecting portion.

[0017] In one of the embodiments: one end of the weight-reducing groove axially penetrates the connecting portion.

[0018] By adopting the above technical solution, the weight-reducing groove is set to achieve lightweight, while the through-setting can increase the length of the weight-reducing groove.

[0019] In one of the embodiments: the other end of the weight-reducing groove is arranged in an inclined surface.

[0020] By adopting the above technical solution, when the length of the weight-reducing groove is too long, it is easy to affect the structural strength of the connection part. Therefore, by setting the inclined surface, the influence on the structural strength of the connection part can be reduced while increasing the length of the weight-reducing groove.

[0021] In one of the embodiments: the height of the connecting portion is lower than the height of the locking rib, and the portion of the locking rib that is higher than the connecting portion is configured in a conical shape.

[0022] By adopting the above technical solution, the lightweight can be achieved as much as possible while ensuring the strength of the locking ribs.

[0023] In one of the embodiments: the weight-reducing groove is provided with reinforcing ribs arranged along the axial direction.

[0024] By adopting the above technical solution and setting reinforcing ribs, the structural strength of the connection part can be guaranteed when the depth and width of the weight-reducing groove are large. BRIEF DESCRIPTION OF THE DRAWINGS
