[0026] In order to make the purpose, technical solution and advantages of the embodiment of the utility model clearer, the technical solution of the embodiment of the utility model will be clearly and completely described below in conjunction with the drawings of the embodiment of the utility model. Obviously, the described embodiment is a part of the embodiment of the utility model, not all of the embodiments. Based on the described embodiment of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.
[0027] Example 1: Please refer to Figures 1 to 6 :
[0028] The utility model provides a low-loss and high-wear-resistant automobile bearing, comprising: an inner ring 1;
[0029] An outer ring 2 is installed on the outside of the inner ring 1. The inner ring 1 and the outer ring 2 are used to support the retainer 3 and the roller 4. A retainer 3 is installed between the inner ring 1 and the outer ring 2. When the bearing rotates, the inner ring 1 will rotate inside the outer ring 2. At this time, the roller 4 will roll in the circular tracks on the inner ring 1 and the outer ring 2. At the same time, the retainer 3 will keep the position of the roller 4 to prevent the rollers 4 from colliding and rubbing against each other. A total of eight rollers 4 are rotatably installed on the inner side of the retainer 3. When the bearing rotates, the inner ring 1 will rotate inside the outer ring 2. At this time, the roller 4 will roll in the circular tracks on the inner ring 1 and the outer ring 2. A dust baffle 5 is fixed on the front and rear outer sides of the inner ring 1. The inner ring 1 rotates When the inner ring 1 rotates, the dust baffles 5 on the front and rear sides will also rotate synchronously. The thin plates on the outside of the dust baffles 5 cooperate with the annular grooves on the front and rear sides of the outer ring 2 to seal the inside of the bearing and prevent dust from entering the inside of the bearing. Sixteen air guide covers 6 are fixed on the outside of the dust baffles 5 in a circular arrangement. When the inner ring 1 rotates, the opening on the air guide covers 6 on one side will face the direction of rotation. Therefore, external air can enter the U-shaped through holes on the inner ring 1 and the dust baffle 5 through the opening on the air guide covers 6, and then the air will be discharged to the outside through the opening on the other side of the U-shaped through hole. In this way, the inner ring 1 can be cooled and the aging rate of the lubricating oil in the bearing due to high temperature can be slowed down.
[0030] In the present disclosure, Figure 1 , Figure 2 and Figure 5 As shown, an annular groove is provided on the front and rear sides of the inner wall of the outer ring 2, and the steel balls on the outside of the dust baffle 5 can roll in the annular grooves on the front and rear sides of the inner wall of the outer ring 2. When the inner ring 1 rotates, the dust baffles 5 on its front and rear sides will also rotate synchronously. At the same time, the steel balls on the outside of the dust baffle 5 will also roll in the annular grooves on the front and rear sides of the inner wall of the outer ring 2, reducing the friction between the dust baffle 5 and the outer ring 2, and at the same time can also play an auxiliary supporting role for the outer ring 2, thereby improving the bearing strength.
[0031] In the present disclosure, Figure 1 , Figure 2 and Figure 4 -As shown in Figure 6, three annular grooves are equidistantly arranged in the annular tracks on the inner ring 1 and the outer ring 2 that cooperate with the roller 4. When the bearing rotates, the inner ring 1 will rotate inside the outer ring 2. At this time, the roller 4 will roll in the annular tracks on the inner ring 1 and the outer ring 2. At the same time, the cage 3 will maintain the position of the roller 4 to prevent the rollers 4 from colliding and rubbing against each other. In addition, part of the lubricating oil will enter the annular grooves in the annular tracks on the inner ring 1 and the outer ring 2, so the roller 4 can be fully lubricated, thereby reducing loss and improving wear resistance.
[0032] In the present disclosure, Figure 1-Figure 4 As shown, a total of sixteen U-shaped through holes are provided on the inner ring 1 and the dust baffle 5, and the air guide covers 6 are respectively provided at the front and rear opening positions of these U-shaped through holes. When the inner ring 1 rotates, the opening on one side of the air guide cover 6 will face the rotation direction, so the external air can enter the inner ring 1 and the U-shaped through holes on the dust baffle 5 through the opening on the air guide cover 6, and then the air will be discharged outward through the opening on the other side of the U-shaped through holes, so that the inner ring 1 can be cooled and the aging rate of the lubricating oil in the bearing due to high temperature can be slowed down.
[0033] In the present disclosure, Figure 1 and Figure 2 As shown, a thin plate is provided on the outside of the dust baffle 5, and an annular groove corresponding to the size of the thin plate on the outside of the dust baffle 5 is also provided on the front and rear sides of the outer ring 2. The thin plate on the outside of the dust baffle 5 can rotate in the annular grooves on the front and rear sides of the outer ring 2. When the inner ring 1 rotates, the dust baffles 5 on the front and rear sides will also rotate synchronously. The thin plate on the outside of the dust baffle 5 cooperates with the annular grooves on the front and rear sides of the outer ring 2 to seal the inside of the bearing to prevent dust from entering the inside of the bearing.
[0034] In the present disclosure, Figure 1 , Figure 2 and Figure 4 As shown, a number of steel balls are rotatably installed on the outer side of the dust baffle 5, and two-thirds of these steel balls are located on the inner side of the dust baffle 5. When the inner ring 1 rotates, the dust baffles 5 on the front and rear sides thereof will also rotate synchronously. At the same time, the steel balls on the outer side of the dust baffle 5 will also roll in the annular grooves on the front and rear sides of the inner wall of the outer ring 2, reducing the friction between the dust baffle 5 and the outer ring 2, and at the same time can also play an auxiliary supporting role for the outer ring 2, thereby improving the bearing strength.
[0035] Embodiment 2, based on embodiment 1, as Figure 1-Figure 6As shown, the air guide hood 6 is an arc-shaped plate with an opening on one side, and the opening of the air guide hood 6 located on the front side of the bearing is facing clockwise, and the opening of the air guide hood 6 located on the rear side of the bearing is facing counterclockwise. When the inner ring 1 rotates, the opening on one side of the air guide hood 6 will face the rotation direction, so the external air can enter the U-shaped through hole on the inner ring 1 and the dust baffle 5 through the opening on the air guide hood 6, and then the air will be discharged to the outside through the opening on the other side of the U-shaped through hole, so that the inner ring 1 can be cooled and the aging rate of the lubricating oil in the bearing due to high temperature can be slowed down.
[0036] The working principle of this embodiment is as follows: when the bearing rotates, the inner ring 1 will rotate inside the outer ring 2, and at this time, the rollers 4 will roll in the annular tracks on the inner ring 1 and the outer ring 2, and at the same time, the retaining frame 3 will maintain the position of the rollers 4 to prevent the rollers 4 from colliding and rubbing against each other, and a part of the lubricating oil will enter the annular grooves in the annular tracks on the inner ring 1 and the outer ring 2, so that the rollers 4 can be fully lubricated, thereby reducing losses and improving wear resistance, and when the inner ring 1 rotates, the dust baffles 5 on the front and rear sides thereof will also rotate synchronously, and the thin plates on the outside of the dust baffles 5 cooperate with the annular grooves on the front and rear sides of the outer ring 2 to seal the inside of the bearing to prevent dust from entering. Dust enters the inside of the bearing, and the steel balls on the outside of the dust baffle 5 will also roll in the annular grooves on the front and rear sides of the inner wall of the outer ring 2, reducing the friction between the dust baffle 5 and the outer ring 2, and at the same time can also play an auxiliary supporting role for the outer ring 2, thereby improving the bearing strength. When the inner ring 1 rotates, the opening on the air guide cover 6 on one side will face the direction of rotation, so the outside air can enter the inner ring 1 and the U-shaped through hole on the dust baffle 5 through the opening on the air guide cover 6, and then the air will be discharged outward through the opening on the other side of the U-shaped through hole, so that the inner ring 1 can be cooled and the aging rate of the lubricating oil in the bearing due to high temperature can be slowed down.
