DETAILED DESCRIPTION
[0026] The technical solution of this patent is further described in detail below in conjunction with specific implementation methods.
[0027] like Figures 1-4 As shown, the utility model provides a technical solution: a high-load angular contact ball bearing, comprising an outer ring 1, an inner ring 6 and a retainer 4, a plurality of balls 5 are arranged on the outer surface of the retainer 4, the retainer 4 and the balls 5 are located between the outer ring 1 and the inner ring 6, a positioning device 2 is arranged on the outer surface of the inner ring 6, the positioning device 2 comprises a plurality of positioning rods 25, a plurality of slide grooves 22 are provided on one side of the top end of the inner ring 6, a slider 23 is slidably connected to the inner wall of the slide groove 22, one side of the slider 23 is fixedly connected to one end of the positioning rod 25, a spring 24 is arranged on one side of the slider 23, two ends of the spring 24 are respectively fixedly connected to one side of the slider 23 and one side of the inner wall of the slide groove 22, and a plurality of U-shaped blocks 21 are respectively fixedly connected to the top of the outer ring 1 and the retainer 4 By setting the slider 23, when the bearing is spliced, the ball 5 is first embedded in the placement groove on the outer surface of the retainer 4, and then the retainer 4 is placed inside the outer ring 1, and the four positioning rods 25 at the top of the inner ring 6 are pressed to make the slider 23 at the bottom of the positioning rod 25 slide on the inner wall of the slide groove 22 and compress the spring 24, and the inner ring 6 is placed inside the retainer 4, and then the positioning rod 25 is released. The spring 24 inside the slide groove 22 returns to its original state and pushes the slider 23 to slide, and the positioning rod 25 on one side of the slider 23 is inserted into the U-shaped block 21 at the top of the retainer 4 and the top of the outer ring 1, and the angle between the retainer 4 and the outer ring 1 and the inner ring 6 is further limited, so as to avoid the angle deviation after the bearing is installed as much as possible, which affects the use effect of the bearing.
[0028] Specifically, Figures 2-4As shown, a groove block 28 is fixedly connected to the top end of the positioning rod 25. A groove is formed on one side of the groove block 28. By pressing against the groove on the outer surface of the groove block 28 with hand, it is more convenient to push the groove block 28 to control the moving position of the slider 23. Two inclined rods 27 are fixedly connected to one side of the slider 23. The ends of the two inclined rods 27 far away from the slider 23 are fixedly connected to both sides of the positioning rod 25. By setting the inclined rods 27, the connection between the positioning rod 25 and the slider 23 can be strengthened, and the stability of the connection structure between the positioning rod 25 and the slider 23 can be improved.
[0029] Specifically, as Figures 2-4 shown, a round rod 26 is fixedly connected to the inner wall of the sliding groove 22. The slider 23 slides on the outer surface of the round rod 26. When the slider 23 slides on the inner wall of the sliding groove 22, it will move on the outer surface of the round rod 26. By means of the round rod 26, the angle between the slider 23 and the sliding groove 22 can be further restricted, and it is possible to avoid as much as possible the angle deviation between the slider 23 and the sliding groove 22 and the positioning rod 25. The diameter of the round rod 26 is slightly smaller than the inner diameter of the spring 24. The spring 24 is located outside the round rod 26. By setting the round rod 26, the internal shape of the spring 24 can be strengthened, and it is possible to avoid as much as possible the spring 24 being distorted when the slider 23 moves and deforms the spring 24.
[0030] Specifically, as Figure 1 、 Figure 2 、 Figure 3 and Figure 5 shown, an anti-slip device 3 is arranged inside the inner ring 6. The anti-slip device 3 includes an anti-slip ring 35. A number of convex pieces are arranged on the inner wall of the anti-slip ring 35. A number of insertion rods 33 are fixedly connected to the outer surface of the anti-slip ring 35. Card slots 34 are formed on both sides of the insertion rods 33. A number of insertion slots 31 are formed on the inner wall of the inner ring 6. Convex blocks 32 are fixedly connected to both sides of the inner wall of the insertion slots 31. When installing the bearing, the respective insertion rods 33 on the outer surface of the anti-slip ring 35 can be respectively inserted into the respective insertion slots 31 inside the inner ring 6, so that the two convex blocks 32 on the inner wall of the insertion slots 31 are stuck at the card slots 34 on the outer surface of the insertion rods 33, fixing the insertion rods 33 inside the insertion slots 31, installing the anti-slip ring 35 inside the inner ring 6, and making the anti-slip ring 35 located between the shaft and the inner ring 6. By means of the anti-slip ring 35, the friction force at the contact between the inner ring 6 and the shaft can be increased, so that the shaft and the inner ring 6 are not prone to slipping during rotation. A number of rectangular grooves 36 are formed on the inner wall of the anti-slip ring 35. The rectangular grooves 36 are respectively located on the upper and lower sides of the inner wall of the anti-slip ring 35. When it is necessary to take out the anti-slip ring 35, a tool can be used to hook at the rectangular grooves 36 on the upper and lower sides of the inner wall of the anti-slip ring 35, and it is more convenient to pull the anti-slip ring 35 to remove the anti-slip ring 35.
[0031] The working principle of the present utility model is as follows:
[0032] S1. When installing the bearing, first embed the balls 5 inside the placement grooves on the outer surface of the cage 4, and then place the cage 4 inside the outer ring 1. Press the four positioning rods 25 at the top end of the inner ring 6 so that the sliders 23 at the bottom ends of the positioning rods 25 slide on the inner wall of the chute 22 and compress the spring 24. Place the inner ring 6 inside the cage 4, and then release the positioning rods 25. The spring 24 inside the chute 22 will return to its original state and push the sliders 23 to slide. Insert the positioning rods 25 on one side of the sliders 23 into the U-shaped blocks 21 at the top ends of the cage 4 and the outer ring 1 to further limit the angle between the cage 4, the outer ring 1, and the inner ring 6.
[0033] S2. When connecting the bearing to the shaft, insert the respective insertion rods 33 on the outer surface of the anti-slip ring 35 into the respective slots 31 inside the inner ring 6, so that the two protrusions 32 on the inner wall of the slot 31 are stuck at the card slots 34 on the outer surface of the insertion rod 33, fixing the insertion rod 33 inside the slot 31. Install the anti-slip ring 35 inside the inner ring 6 so that the anti-slip ring 35 is located between the shaft and the inner ring 6. The anti-slip ring 35 can increase the friction at the contact between the inner ring 6 and the shaft, making it not easy for the shaft and the inner ring 6 to slip when rotating.
