Technical Field

[0001] The utility model relates to the technical field of bearing manufacturing, in particular to a bearing structure with a slewing support sleeve. Background Technique

[0002] The slewing support sleeve bearing is a special type of bearing, mainly used to support and control the slewing motion. It usually consists of inner and outer tracks, rolling elements (usually balls or rollers), and sealing or isolating blocks, etc. Such bearings are usually widely used in equipment and mechanical systems that require slewing or swinging motion.

[0003] However, for the existing bearing with a slewing support sleeve, when the isolating block is installed into the bearing interior through the installation channel, the space at the interface between the installation channel and the rolling groove inside the bearing is relatively large, and the isolating block is prone to flip at this position. Therefore, it is easy to cause the installation direction of the isolating block to be incorrect. When the installation direction of the isolating block is incorrect, it will cause vibration or unstable motion of the bearing during operation, affecting the overall performance of the bearing.

[0033] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without making creative efforts belong to the scope of protection of the present utility model.

[0034] Please refer to Figure 5 - Figure 6 , the present utility model provides a technical solution: a bearing structure with a slewing support sleeve, including an inner ring 6, an installation channel 7 is opened inside the inner ring 6, a limiting component is arranged inside the inner ring 6, a closing block 8 is connected inside the installation channel 7, and a positioning component is connected to the outer surface of the closing block 8;

[0035] Please refer to Figure 5 - Figure 6 , the limiting component includes a limiting baffle 9, a slide block 10 is fixedly connected to one side of the limiting baffle 9, and a guide rod 12 is fixedly connected to one side of the slide block 10.

[0036] The principle that can ensure the closing block 8 is installed in the correct position is: the return spring 11 pushes the slide block 10 to move towards the outside of the inner ring 6, so that the limiting baffle 9 slides into the rolling groove between the inner ring 6 and the outer ring 1, thereby reducing the space at the connection between the installation channel 7 and the rolling groove. The spacer block 4 is limited by the upper and lower limiting baffles 9 to prevent the spacer block 4 from flipping randomly during the installation process.

[0037] Please refer to Figure 1 - Figure 4 , a rolling element 3 is arranged on the outside of the inner ring 6, a spacer block 4 is connected between the rolling elements 3, an outer ring 1 is arranged on the outside of the rolling element 3 and the spacer block 4, a mounting hole 2 is opened inside the outer ring 1, and sealing strips 5 are respectively connected to both sides of the inner ring 6 and the outer ring 1.

[0038] It is worth mentioning that: the rolling element 3 and the spacer block 4 can roll in the rolling groove between the inner ring 6 and the outer ring 1, and the sealing strip 5 is used to dust-proof and seal the bearing.

[0039] Please refer to Figure 5 - Figure 8, the connection mode between the closing block 8 and the installation channel 7 is a sliding connection. The closing block 8 is in close fit with the installation channel 7. A clamping groove 15 and a positioning hole 16 are formed on one side of the closing block 8, and the clamping groove 15 and the positioning hole 16 communicate with each other.

[0040] It should be noted that: the closing block 8 can close the installation channel 7 to prevent impurities such as dust from entering the bearing through the installation channel 7 and contaminating the bearing. The closing block 8 is connected to the positioning component through the clamping groove 15 and the positioning hole 16, so as to connect the closing block 8 with the inner ring 6 and prevent the closing block 8 from falling off from the inside of the installation channel 7.

[0041] Please refer to Figure 1 - Figure 6 , the limit baffles 9 are symmetrically distributed about the horizontal center line of the inner ring 6. One side of the closing block 8 and the limit baffles 9 is an arc surface. The side surfaces of the inner ring 6, the closing block 8 and the limit baffles 9 together form a complete arc-shaped groove. One side of the slider 10 is fixedly connected with a return spring 11, and the other end of the return spring 11 is connected with the inner ring 6. The slider 10 forms a telescopic structure inside the inner ring 6 through the return spring 11.

[0042] The function of the limit baffle 9 is that: the arc-shaped structure of the closing block 8 and the limit baffle 9 is beneficial to ensure the integrity of the arc-shaped rolling groove in the inner ring 6. When the slider 10 moves towards the inner side of the inner ring 6, the closing block 8 can be pushed out of the installation channel 7 through the limit baffle 9. When the return spring 11 pushes the slider 10 to move towards the outer side of the inner ring 6, the upper and lower limit baffles 9 can limit the isolation block 4 to prevent the isolation block 4 from flipping randomly during the installation process.

[0043] Please refer to Figure 5 - Figure 8 , the positioning component includes a positioning rod 13. One end of the positioning rod 13 is rotatably connected with a guide rod 12, and the other end of the positioning rod 13 is connected with a bolt 14. The thickness of the positioning rod 13 is equal to the thickness of the clamping groove 15. The bolt 14 passes through the positioning rod 13 and is connected with the positioning hole 16;

[0044] It should be noted that: since the thickness of the positioning rod 13 is equal to the thickness of the clamping groove 15, it is convenient for the positioning rod 13 to be accurately clamped into the clamping groove 15, and at the same time, the integrity of the outer surface structure of the inner ring 6 is ensured. The positioning rod 13 can be stably connected with the closing block 8 through the bolt 14.

[0045] Although the embodiments of the present invention have been shown and described, for those of ordinary skill in the art, it can be understood that various changes, modifications, substitutions and variations can be made to these embodiments without departing from the principle and spirit of the present invention. The scope of the present invention is defined by the appended claims and their equivalents.
