Description

Technical Field

[0001] This utility model relates to the field of retainer technology, and in particular to a high-load, low-speed bearing retainer. Background Technology

[0002] Bearings are an important component in modern mechanical equipment. Their main function is to support rotating mechanical parts, reduce the coefficient of friction during their movement, and ensure their rotational accuracy. The bearing cage is one of the main components of the bearing. Its main function is to evenly separate the rolling elements in the bearing, thereby ensuring smooth bearing operation and keeping the rolling elements from detaching from the bearing at all times. Existing bearings are installed inside various devices. When the bearing is subjected to high rotational loads, the bearing cage will bear a large impact force. Moreover, the capacity loss of the bearing cage increases during operation, and the rotational friction is large. Therefore, the service life of both the bearing cage and the bearing will be affected.

[0003] Therefore, designing a high-load, low-speed bearing retainer is a problem that urgently needs to be solved. Utility Model Content

[0004] The purpose of this invention is to solve the problems in the prior art by providing a high-load, low-speed bearing retainer, thereby addressing the issues of bearing retainer and bearing lifespan when bearings rotate at high load and low speed.

[0005] The technical solution of this utility model is:

[0006] A high-load, low-speed bearing retainer includes an inner bearing ring and an outer bearing ring. The inner bearing ring is disposed inside the outer bearing ring, and balls are installed between the inner and outer bearing rings. A retainer is provided between the inner and outer bearing rings, and the retainer has multiple spherical pockets spaced apart. A support platform is provided between two adjacent pockets, and the height of the support platform is higher than the bottom of the pocket. The two ends of the pocket extend out of the support platform to form retaining edges. The opening diameter of the outer ring of the pocket is larger than the opening diameter of the inner ring of the pocket. The balls are installed inside the pockets.

[0007] As a preferred technical solution, the outer side of the inner ring of the bearing has an arc-shaped inner ring groove, and the inner side of the outer ring of the bearing has an arc-shaped outer ring groove. The inner ring groove and the outer ring groove are positioned correspondingly, and the ball is installed between the inner ring groove and the outer ring groove.

[0008] As a preferred technical solution, the pocket is located within the arcuate space between the inner ring groove and the outer ring groove.

[0009] As a preferred technical solution, the pocket is a spherical hole with an open top, and the vertical distance from the upper edge of the pocket to the bottom is greater than the radius of the pocket and smaller than the diameter of the pocket.

[0010] As a preferred technical solution, the distance from the support platform to the bottom of the pocket corresponds to the vertical height of the retaining edge.

[0011] Compared with the prior art, the beneficial effects of this utility model are:

[0012] This utility model relates to a high-load, low-speed bearing retainer. A retainer is installed between the inner and outer rings of the bearing. The retainer has a spherical pocket and a support platform. The two ends of the pocket are provided with retaining edges. By setting the height of the support platform higher than the bottom of the pocket, and the opening diameter of the outer ring of the pocket being larger than the opening diameter of the inner ring, the strength of the retainer pocket and the support platform is ensured, thereby improving the overall strength of the retainer and ensuring the service life of the retainer and the bearing when the bearing rotates at high load and low speed.

[0020] To make the technical means, technical features, utility model purpose and technical effects of this utility model easier to understand, the present utility model will be further described below with reference to specific illustrations.

[0021] Example

[0022] like Figure 1 and Figure 2 The diagram shown is a structural schematic of the high-load, low-speed bearing retainer of this utility model.

[0023] The high-load, low-speed bearing retainer of this embodiment includes an inner bearing ring 1, an outer bearing ring 3, balls 2, and a retainer 4. The inner bearing ring 1 is installed in the outer bearing ring 3, and the balls 2 are installed on the retainer 4. The retainer 4 and the balls 2 are installed between the inner bearing ring 1 and the outer bearing ring 3. When the bearing rotates, the balls 2 reduce the friction between the inner bearing ring 1 and the outer bearing ring 3.

[0024] like Figure 3 The diagram shown is a structural schematic of the bearing outer ring of this utility model. Figure 4 This is a schematic diagram of the bearing inner ring of this utility model.

[0025] The outer ring 3 of the bearing shown has an arc-shaped outer ring groove 31 on its inner side, and the inner ring 1 of the bearing shown has an arc-shaped inner ring groove 11 on its outer side. The outer ring groove 31 and the inner ring groove 11 are positioned correspondingly. The ball 2 is held in the arc-shaped space between the outer ring groove 31 and the inner ring groove 11. When the bearing rotates, the ball 2 rotates in the outer ring groove 31 and the inner ring groove 11. The arc-shaped surface design reduces the resistance when the bearing rotates.

[0026] like Figure 5-6 The diagram shown is a structural schematic of the retainer of this utility model.

[0027] The retainer 4 shown has multiple spherical pockets 42 spaced apart, with a support platform 41 between two adjacent pockets 42. Side flanges 43 extending from the support platform 41 are provided on both sides of the pockets 42. The outer opening diameter of the pocket 42 is larger than the inner opening diameter. When the bearing rotates, the centrifugal force on the outer side of the ball 2 is greater than the force on the inner side due to centrifugal force. Therefore, the retainer 4 limits the movement of the ball 2 during bearing rotation, preventing the ball 2 from jamming. The retainer 4 is less affected by the centrifugal force of the ball, extending its service life and reducing the probability of wear.

[0028] The pocket 42 is a spherical hole with an opening at the top. The vertical distance from the upper edge of the pocket 42 to the bottom is greater than the radius of the pocket 42 but less than the diameter of the pocket. When the bearing rotates, the upper opening of the pocket 42 is smaller than the diameter of the ball 2, which plays a role in limiting the ball 2 and ensuring that the retainer 4 has good rigidity and is not easily damaged or deformed.

[0029] The height of the support platform 41 is higher than the bottom of the pocket 42. The distance from the support platform 41 to the bottom of the pocket 42 corresponds to the vertical height of the retaining edge 43. The retaining edge 43 not only serves as a limit but also ensures good rigidity and strength, preventing the balls 2 from being damaged or deformed due to rotational force and centrifugal force when the bearing rotates, thus meeting the high load requirements of the retainer 4.

[0030] The above description is merely a preferred embodiment of this utility model and is not intended to limit the scope of this utility model. All equivalent changes and modifications made in accordance with the scope of the claims of this utility model should fall within the technical scope of this utility model.
