Description

Technical Field

[0001] This utility model belongs to the field of deep groove ball bearing technology, specifically relating to a deep groove ball bearing assembly with an outer ring pressure plate. Background Technology

[0002] The common configuration for bearings is a fixed end + floating end. The fixed end bearing needs to be axially fixed. However, existing deep groove ball bearings lack a good axial positioning method, which affects the stability of bearing operation. Summary of the Invention

[0003] In view of the defects of the prior art, the purpose of this utility model is to provide a deep groove ball bearing assembly with an outer ring pressure plate, which can axially fix the bearing through the pressure plate.

[0004] To achieve the above objectives, the technical solution adopted by this utility model is as follows: a deep groove ball bearing assembly with an outer ring and a pressure plate, comprising an inner ring, an outer ring, steel balls, a cage, and a pressure plate. The inner ring and the outer ring are coaxially arranged, and a plurality of steel balls are held between the inner ring and the outer ring by the cage. The pressure plate is detachably mounted on the outer diameter surface of the outer ring, and the pressure plate is provided with a plurality of circumferentially evenly distributed flanges, and threaded holes for connection and positioning are formed on the flanges.

[0005] Furthermore, the pressure plate is assembled onto the outer diameter surface of the outer ring via a threaded connection.

[0006] Furthermore, a stepped platform is provided at one end of the outer diameter surface of the outer ring. The diameter of the stepped platform is smaller than that of the outer diameter of the outer ring. The cylindrical surface of the stepped platform is provided with threads, and the inner diameter of the pressure plate is provided with matching threads. The pressure plate is connected to the stepped platform of the outer diameter of the outer ring through the inner diameter threads.

[0007] Furthermore, one end face of the pressure plate is flush with one end face of the outer ring. Engravings are made on the flush end faces of the pressure plate and the outer ring to lock the threads and prevent the pressure plate from rotating and falling off.

[0008] Furthermore, the deep groove ball bearing assembly is mounted on the shaft, and the thread direction of the pressure plate is opposite to the rotation direction of the shaft. This prevents the bearings from coming off during operation.

[0009] Furthermore, the deep groove ball bearing assembly is connected and fixed to the housing of the external component through the flange of the pressure plate. The number of flanges is consistent with the number of threaded holes in the housing of the external component. The threaded holes in the housing are adapted to the threaded holes of the flanges and are connected by bolts.

[0010] Furthermore, the circumference is divided into three flanges.

[0011] Furthermore, the deep groove ball bearing assembly is mounted on the shaft, with the inner ring having an interference fit with the shaft.

[0012] Furthermore, a retaining cover is fixedly connected to the end of the shaft, and the deep groove ball bearing assembly is assembled at the shaft shoulder. The two ends of the inner ring are axially fixed through the shaft shoulder and the retaining cover.

[0013] The beneficial effects of this utility model are as follows: This utility model adds a pressure plate design with a threaded hole on the outer diameter surface of the deep groove ball. The pressure plate is used to position the bearing axially. The pressure plate and the bearing are detachably connected. The pressure plate can be replaced, which facilitates the connection of the bearing to different external components. The external structure is connected through the pressure plate, avoiding drilling holes directly on the bearing, which is beneficial to the stability of the bearing assembly.

[0018] To make the above-mentioned objects, features, and advantages of this utility model more apparent and understandable, the specific embodiments of this utility model will be described in detail below with reference to the accompanying drawings. Many specific details are set forth in the following description to provide a full understanding of this utility model. However, this utility model can be implemented in many other ways different from those described herein, and those skilled in the art can make similar modifications without departing from the spirit of this utility model. Therefore, this utility model is not limited to the specific embodiments disclosed below.

[0019] See appendix Figure 1-3 A deep groove ball bearing assembly with an outer ring and a pressure plate includes an inner ring 1, an outer ring 2, steel balls 3, a cage 4, and a pressure plate 5. The inner ring 1 and the outer ring 2 are coaxially arranged, and a plurality of steel balls 3 are held between the inner ring 1 and the outer ring 2 by the cage 4. The pressure plate 5 is detachably mounted on the outer diameter surface of the outer ring 2. The pressure plate 5 is provided with three circumferentially evenly spaced flanges 5.1. The flanges 5.1 are formed with threaded holes for connection and positioning. The threaded holes of the pressure plate flanges are adapted to the threaded holes of the external component housing 8 and are connected by bolts.

[0020] Furthermore, the pressure plate 5 is threadedly assembled onto the outer diameter surface of the outer ring. One end of the outer diameter surface of the outer ring is provided with a stepped platform 2.1, the diameter of which is smaller than the outer diameter of the outer ring 2. The cylindrical surface of the stepped platform 2.1 is provided with threads 2.2, and the inner diameter of the pressure plate 5 is provided with matching threads. The pressure plate 5 is connected to the stepped platform 2.1 on the outer diameter of the outer ring via these inner diameter threads. The stepped platform serves to limit the pressure plate's position, improving the stability of the pressure plate assembly.

[0021] Furthermore, one end face of the pressure plate 5 is flush with one end face of the outer ring 2. Engravings are made on the flush end face of the pressure plate and the end face of the outer ring. These are used to lock the threads and prevent the pressure plate from rotating and falling off.

[0022] Furthermore, the deep groove ball bearing assembly is mounted on the shaft 6, and the thread direction of the pressure plate 5 is opposite to the rotation direction of the shaft 6. This prevents the bearing from coming off during operation.

[0023] Furthermore, the deep groove ball bearing assembly is mounted on the shaft 6, with the inner ring 1 having an interference fit with the shaft 6. The shaft 6 is a hollow shaft, with a retaining cover 7 fixedly connected to the end of the shaft 6. The deep groove ball bearing assembly is assembled at the shaft shoulder 6.1, and the two ends of the inner ring 1 are axially fixed through the shaft shoulder 6.1 and the retaining cover 7.

[0024] The deep groove ball bearing with an outer ring and pressure plate designed here mainly consists of an outer ring 2, an inner ring 1, a cage 4, steel balls 3, and a pressure plate 5. The inner ring 1 is interference-fitted with the shaft 6 and axially fixed to the shaft shoulder 6.1 and the retainer 7, achieving axial and radial fixation of the inner ring 1. The pressure plate 5 is mounted on the external component housing 8. The pressure plate 5 has three circumferentially divided flanges 5.1, which mate with threaded holes on the housing 8. It is fixed with bolts to achieve axial fixation of the outer ring. The outer ring stepped platform 2.1 has threads 2.2, and the inner diameter of the pressure plate 5 has the same mating threads. The thread direction is opposite to the shaft rotation direction to prevent disengagement during operation. Additionally, markings are chiseled on the end faces of the outer ring 2 and the pressure plate 5 to prevent the pressure plate 5 from falling off.
