Description

Technical Field

[0001] The utility model discloses a bearing ring with positioning and installation functions, belonging to the technical field of bearing rings. Background Art

[0002] Bearing rings include inner rings and outer rings, which are one of the core components of bearings and together with rolling elements and cages constitute the main structure of bearings. Rings are usually made of high-strength materials (such as high-carbon chromium steel, stainless steel) to ensure their wear resistance and long service life under high load and high speed conditions. The size and shape of the rings need to be highly precise to ensure precise matching with rolling elements and cages, thereby ensuring the performance and stability of the bearings. When selecting bearing rings, it is necessary to consider factors such as specific application scenarios, load types, working environments (such as temperature and humidity), and bearing life to ensure their optimal performance and reliability under specific conditions.

[0003] In the prior art, the retaining frame that wraps the rolling body is directly embedded in the raceway of the inner ring surface of the bearing outer ring, and no other positioning reinforcement is performed on the retaining frame. When the bearing inner ring is not installed, the retaining frame and the rolling body are prone to fall off from the inner part of the bearing outer ring, thereby reducing the bearing installation stability and installation efficiency.

[0004] In summary, the utility model provides a bearing ring with positioning and installation function to solve the above problems. Utility Model Content

[0005] In view of the deficiencies in the prior art, the utility model aims to provide a bearing ring with a positioning and installation function to solve the problem in the above background technology that the retaining frame cannot be positioned, reinforced and prevented from falling off inside the raceway of the bearing outer ring.

[0006] In order to achieve the above-mentioned purpose, the utility model is implemented through the following technical scheme: a bearing ring with a positioning and installation function, comprising a bearing outer ring, a retaining frame and a rolling body wrapped inside the retaining frame, the inner ring surface of the bearing outer ring is provided with an annular groove, the retaining frame is clamped to the inside of the annular groove, the inner ring surface of the annular groove is evenly provided with spherical grooves, the rolling bodies wrapped on the retaining frame are all spherical, and the rolling bodies on the retaining frame are embedded in the inside of the annular groove through the spherical grooves, and fastening screws are penetrated around the top and bottom of the bearing outer ring and are respectively located directly above the top and below the bottom of the retaining frame.

[0007] Furthermore, one end of the fastening screw passes through the annular groove and extends to the interior of the retaining frame body.

[0008] Furthermore, the top and bottom of the retaining frame are fixedly connected to the outer ring of the bearing by four fastening screws.

[0009] Furthermore, the fastening screw is threadedly connected to the outer ring of the bearing, and the fastening screw is threadedly connected to the retaining frame.

[0010] Furthermore, threaded holes for threaded connection with fastening screws are provided around the top and bottom of the retaining frame.

[0011] Furthermore, threaded holes for threaded connection with fastening screws are provided around the top and bottom of the outer ring of the bearing.

[0012] Furthermore, an annular groove is formed on the outer ring surface of the bearing outer ring, and a plurality of anti-slip grooves are evenly formed on the ring surface of the annular groove.

[0013] Beneficial effects of the utility model:

[0014] The retainer is quickly embedded into the raceway of the outer ring of the bearing through the annular groove, and each rolling element is embedded in the corresponding spherical groove. At the same time, the end of the threaded hole on the outer ring of the bearing is aligned with the end of the threaded hole on the retainer. The top and bottom of the retainer are fixedly connected to the top and bottom of the inner ring raceway of the outer ring of the bearing with the tightening screws respectively. After the rolling element is installed in the outer ring of the bearing through the retainer, the retainer will not loosen due to the failure to install the inner ring of the bearing, and the rolling element will not fall off. This effectively improves the bearing installation stability and installation efficiency.

[0015] The annular groove and the anti-skid groove are both opened on the outer ring surface of the bearing outer ring by integral casting. The multiple anti-skid grooves can increase the friction force when holding the outer ring surface of the bearing outer ring. By inserting fingers into the inside of the annular groove to hold the bearing outer ring, the bearing outer ring can be effectively prevented from slipping during installation, thereby improving the assembly efficiency of the bearing ring.

[0022] In order to make the technical means, creative features, objectives and effects achieved by the present invention easy to understand, the present invention is further described below in conjunction with specific implementation methods.

[0023] See also Figure 1-4The utility model provides a technical solution: a bearing ring with a positioning and installation function, comprising a bearing outer ring 1, a retainer 2 and a rolling element 3 wrapped inside the retainer 2, an annular groove 4 is opened on the inner ring surface of the bearing outer ring 1, the retainer 2 is clamped into the inside of the annular groove 4, and spherical grooves 5 are evenly opened on the inner ring surface of the annular groove 4. The rolling elements 3 wrapped on the retainer 2 are all spherical, and the rolling elements 3 on the retainer 2 are embedded in the inside of the annular groove 4 through the spherical grooves 5. The four sides of the top and the four sides of the bottom of the bearing outer ring 1 are respectively located directly above the four sides of the top and the four sides of the bottom of the retainer 2. There are fastening screws 6 running through each side. The cage 2 is used to keep the rolling elements 3 (such as balls or rollers) evenly distributed between the inner and outer rings of the bearing to ensure that they do not contact and rub during operation. The materials of the cage 2 are usually metal (such as steel, brass) and non-metal (such as nylon, polyamide). When selecting materials, factors such as the application environment, working temperature and load of the bearing should be considered. The outer ring 1 of the bearing is mainly used to support the radial load or axial load of the shaft and evenly distribute these loads to the bearing seat or the corresponding support structure. The inner surface of the outer ring 1 of the bearing is usually processed into a raceway, and the rolling elements 3 roll on the raceway. In order to achieve low-friction rotational motion, when multiple rolling elements 3 are embedded into the raceway of the inner ring surface of the bearing outer ring 1 through the retaining frame 2, the retaining frame 2 can be quickly embedded with the raceway inside the bearing outer ring 1 through the annular groove 4, and each rolling element 3 is embedded into the corresponding spherical groove 5, and at the same time, the end of the threaded hole opened on the bearing outer ring 1 is aligned with the end of the threaded hole opened on the retaining frame 2. One end of the fastening screw 6 passes through the annular groove 4 and extends to the inside of the retaining frame 2. The top and bottom of the retaining frame 2 are fixedly connected to the bearing outer ring 1 through four fastening screws 6. The fastening screws 6 are fixed to the shaft The outer ring 1 of the bearing is threadedly connected, the fastening screws 6 are threadedly connected to the retaining frame 2, and threaded holes matching the fastening screws 6 are provided around the top and bottom of the retaining frame 2. Threaded holes matching the fastening screws 6 are provided around the top and bottom of the outer ring 1 of the bearing are threadedly connected. The top and bottom of the retaining frame 2 are fixedly connected to the top and bottom of the inner ring raceway of the outer ring 1 of the bearing through the fastening screws 6, respectively, so that after the rolling body 3 is installed inside the outer ring 1 of the bearing through the retaining frame 2, the retaining frame 2 will not loosen and the rolling body 3 will not fall off due to the failure to install the inner ring of the bearing, which effectively improves the installation stability of the bearing.

[0024] See also Figure 2-4An annular groove 7 is provided on the outer ring surface of the bearing outer ring 1, and a plurality of anti-skid grooves 8 are evenly provided on the ring surface of the annular groove 7. The annular groove 7 and the anti-skid groove 8 are both provided on the outer ring surface of the bearing outer ring 1 by integral casting. The plurality of anti-skid grooves 8 can increase the friction force when holding the outer ring surface of the bearing outer ring 1. By inserting fingers into the annular groove 7 to hold the bearing outer ring 1, the phenomenon of slipping of the bearing outer ring 1 during installation can be effectively avoided, thereby improving the assembly efficiency of the bearing ring.

[0025] Specific implementation method: When multiple rolling bodies 3 are embedded into the raceway of the inner ring surface of the bearing outer ring 1 through the retaining frame 2, the retaining frame 2 can be quickly embedded with the raceway inside the bearing outer ring 1 through the annular groove 4, and each rolling body 3 is embedded into the corresponding spherical groove 5, and at the same time, the end of the threaded hole opened on the bearing outer ring 1 is aligned with the end of the threaded hole opened on the retaining frame 2 up and down, and the tightening screws 6 fix the top and bottom of the retaining frame 2 to the top and bottom of the raceway of the inner ring surface of the bearing outer ring 1 respectively, so that after the rolling body 3 is installed in the bearing outer ring 1 through the retaining frame 2, the retaining frame 2 will not loosen due to the failure to install the bearing inner ring, and the rolling body 3 will not fall off, thereby effectively improving the bearing installation stability and installation efficiency.

[0026] The annular groove 7 and the anti-skid groove 8 are both opened on the outer ring surface of the bearing outer ring 1 by integral casting. The multiple anti-skid grooves 8 can increase the friction force when holding the outer ring surface of the bearing outer ring 1. By inserting fingers into the inside of the annular groove 7 to hold the bearing outer ring 1, the bearing outer ring 1 can be effectively prevented from slipping during installation, thereby improving the assembly efficiency of the bearing ring.
