Description

Technical Field

[0001] The present application relates to the technical field of cages, and in particular to a high-speed bearing cage. Background Art

[0002] Cage (i.e. bearing cage, also known as bearing retainer) refers to the bearing parts that partially wrap all or part of the rolling elements and move with them, used to isolate the rolling elements, and usually guide the rolling elements and keep them in the bearing. When the rolling bearing is working, especially when the load is complex and the rotation is high-speed, the cage has to withstand great centrifugal force, impact and vibration. There is great sliding friction between the cage and the rolling elements, and a lot of heat is generated. The combined effect of force and heat will lead to cage failure, and in severe cases, it will cause the cage to burn and break. Therefore, the cage material is required to have good thermal conductivity, good wear resistance, low friction coefficient, low density, certain strength and toughness, good elasticity and stiffness, expansion coefficient similar to the rolling elements, and good processing performance.

The elastic V-shaped plates 7 are all located in the card slots 5 adjacent to them. The storage slots 2 are opened to add paste lubricating oil to the storage slots 2, and the cooperation with the drainage slots 3 can make the paste lubricating liquid in the storage slots 2 melt after the frame 1 becomes hot during the use of the frame 1, so that the paste lubricating liquid can be discharged onto the multiple balls 12, and the balls 12 can be lubricated. By installing the elastic V-shaped plates 7 in cooperation with the card slots 5 and the elastic card plates 6, the two frames 1 can be quickly installed, and the strong stability can prevent the two frames 1 from separating.

[0031] See also Figure 1 , Figure 2 and Figure 3 , Figure 4 The outer surfaces of the two frames 1 are fixedly connected with a plurality of sealing members 8 arranged in a ring, and the two groups of sealing members 8 are symmetrical. The installation of the sealing member can seal the ball 12 in the frame 1 to prevent external impurities from entering the frame 1 and affecting the normal operation of the ball 12. The inner walls of the two frames 1 are provided with a plurality of circumferentially distributed limiting grooves 9, and a plurality of circumferentially distributed limiting members 10 are placed between the two frames 1. The plurality of limiting members 10 are all engaged with the limiting grooves 9 close to them. The installation of the limiting members 10 and the limiting grooves 9 can make the two frames 1 in close contact, so that the two frames 1 can be connected more stably.

The plurality of balls 12 are all located in a seal close to the two frames 1. The balls 12 are located in the seal so that the balls 12 can rotate stably and can prevent foreign impurities from contacting the balls 12. The plurality of elastic clips 6 are all in contact with the elastic V-shaped plates 7 close to the two frames 1. The elastic deformation force of the elastic V-shaped plates 7 is greater than that of the elastic clips 6. The installation of the elastic V-shaped plates 7 and the cooperation of the elastic clips 6 can limit the two frames 1 so that the two frames 1 can be stably connected.

The two frames 1 can be quickly installed by installing the elastic V-shaped plate 7 in cooperation with the card slot 5 and the elastic card plate 6, and the strong stability can prevent the two frames 1 from separating, so that the two frames 1 can be in stable contact with each other, and the installation speed is fast, which improves the installation. For convenience, the limiting member 10 is stuck in the limiting groove 9 at this time, so that it can limit the two frames 1, and the cooperation with the card frame 13 and the card member 14 can stably fix the two frames 1 to avoid separation between the two frames 1. When lubricating liquid is added to the ball 12 in the frame 1, the storage groove 2 can be opened to add paste lubricating oil to the storage groove 2, and the cooperation with the drainage groove 3 can make the paste lubricating liquid in the storage groove 2 melt in the process of using the frame 1 after the frame 1 becomes hot, so that it can be discharged onto multiple balls 12, so that the balls 12 can be lubricated, which is more convenient.

[0034] The working principle of the above embodiment is: when the two frames are installed, the two frames are combined together, and at this time, multiple elastic V-shaped plates will enter the card slots close to them. When the elastic V-shaped plates enter the card slots, they will pop open and contact the inner walls of the card slots. After the elastic V-shaped plates pop open, the elastic card plates can contact and limit the elastic V-shaped plates, so that the elastic V-shaped plates can.
