Description

Technical Field

[0001] This utility model relates to the field of bearing technology, specifically to a split-type bearing. Background Technology

[0002] Split bearings, also known as split bearings, are a special type of bearing where the inner and outer rings or certain components are divided into two parts. They can be installed, disassembled, and maintained by splitting them, without having to completely disassemble the shaft or surrounding structure. Split bearings are used in key parts of electric massage chair core bearing housings, complex joint connections, and large structures to improve maintenance convenience and structural reliability.

[0003] Chinese patent CN213744486U discloses a split-type bearing. By dividing the bearing body into two parts, the bearing can be installed by simply connecting and fixing the left and right half-ring shafts respectively, thus avoiding damage to the shaft and making installation more convenient. The balls are inserted into the slide block, and then the slide block is slid into the "T"-shaped groove to fix the balls on the outer half-ring, preventing the balls from falling out. This makes the split-type bearing more convenient to use.

[0004] In the above scheme, although a ball-bearing cage is constructed by sequentially inserting ball-bearing slides into T-shaped grooves, the use of individual slide splicing results in a certain gap between adjacent slides due to the splicing gap. This can cause the bearing to jam or wobble during operation due to the gap between adjacent slides, thus adversely affecting the service life of the bearing.

[0005] Therefore, this utility model provides a split bearing to solve the above problems. Utility Model Content

[0006] In order to overcome the defects of the prior art, this utility model provides a split bearing to solve the problem that the cage between the inner and outer rings has a certain gap between adjacent slides due to the splicing gap. This gap can cause the bearing to jam or wobble during operation, which in turn has an adverse effect on the service life of the bearing.

[0007] To achieve the above objectives, the technical solution adopted by this utility model is as follows:

[0008] A split bearing includes an outer ring, an inner ring, and a support mechanism. A circumferentially arrayed ball bearing is disposed between the outer ring and the inner ring. The support mechanism includes two first semi-circular frames, two second semi-circular frames, and a connecting assembly. The two first semi-circular frames and the two second semi-circular frames are connected end-to-end to form a ring structure, and the two ring structures form a retainer through the connecting assembly. Each of the two first semi-circular frames has a first receiving groove, and each of the two second semi-circular frames has a second receiving groove. The ball bearing is located between the first receiving groove and the second receiving groove.

[0009] Preferably, the outer ring includes a first semi-ring and a second semi-ring, the first semi-ring having a second groove and the second semi-ring having a first groove.

[0010] Preferably, both ends of the first semi-ring are provided with positioning grooves, and both ends of the second semi-ring are fixedly connected with positioning blocks, and the positioning blocks match the positioning grooves.

[0011] Preferably, the positioning block has a locking hole, the positioning groove has an assembly hole, a first bolt is provided in the assembly hole, and one end of the first bolt passes through the assembly hole and is threaded into the locking hole.

[0012] Preferably, the inner ring includes an inner ring component, on which a receiving cavity is formed.

[0013] Preferably, the connecting assembly includes a limiting screw tube fixedly connected to the second semi-arc frame and a limiting hole opened on the first semi-arc frame, wherein the limiting screw tube matches the limiting hole.

[0014] Preferably, the connecting assembly further includes a second bolt, one end of which passes through a limiting hole and is threaded into a limiting screw tube.

[0015] Preferably, both ends of the first semi-arc frame are provided with second connecting slots, and both ends of the second semi-arc frame are provided with first connecting slots.

[0016] The beneficial effects of this utility model are as follows:

[0017] 1. By using the matching structure of positioning grooves at both ends of the first half-ring and positioning blocks at both ends of the second half-ring, the two outer ring components can be quickly and accurately aligned during splicing, effectively avoiding misalignment. Furthermore, by using the first bolt to pass through the assembly hole and threadedly connect to the locking hole, the connection strength at the splicing point of the outer ring is further strengthened, allowing the outer ring to form a stable annular structure, providing a reliable foundation for the overall operation of the bearing.

[0018] 2. By splicing two first semi-circular frames and two second semi-circular frames to form a ring cage, and then using the locking blocks of the first and second connecting slots to achieve a tight splicing between the semi-circular frames, the splicing gap is eliminated. Then, through the alignment and cooperation of the limiting screw tube and the limiting hole and the locking of the second bolt, the cage structure is made more stable, avoiding jamming or shaking during bearing operation, and significantly extending the service life of the bearing.

[0019] 3. By confining the ball bearing components between the first receiving groove of the first semi-circular frame and the second receiving groove of the second semi-circular frame, and ensuring precise alignment of the grooves through connecting components, the ball bearings are effectively prevented from falling out, ensuring smooth operation of the bearing. The outer ring and cage adopt a split splicing design, combined with the detachable connection structure of bolts and groove blocks, continuing the advantage of split bearings that do not require disassembly of the shaft or surrounding structure, making the installation, disassembly and maintenance process more convenient, and taking into account both reliability and ease of operation.

[0026] The following will refer to the attached reference. Figures 1 to 5 The various embodiments of this utility model will be described in detail below. Those skilled in the art should understand that these embodiments are merely illustrative of the technical principles of this utility model and are not intended to limit the scope of protection of this utility model.

[0027] A split bearing includes an outer ring, an inner ring, and a support mechanism 9. The outer ring includes a first half-ring 1 and a second half-ring 2. The first half-ring 1 has a second sliding groove 10, and the second half-ring 2 has a first sliding groove 4.

[0028] The first semi-ring 1 and the second semi-ring 2 are semi-ring structures of the same specifications, and can form a ring structure after being spliced ​​together. The first groove 4 and the second groove 10 form a ring groove on the inner wall of the ring structure.

[0029] In this embodiment, positioning grooves 12 are provided at both ends of the first semi-ring 1, and positioning blocks 5 are fixedly connected to both ends of the second semi-ring 2, and the positioning blocks 5 match the positioning grooves 12.

[0030] When splicing the first half-ring 1 and the second half-ring 2, the positioning block 5 on the second half-ring 2 needs to be inserted into the positioning groove 12 on the first half-ring 1 to position the first half-ring 1 and the second half-ring 2 and avoid misalignment between the first half-ring 1 and the second half-ring 2.

[0031] In this embodiment, the positioning block 5 is provided with a locking hole 6, the positioning groove 12 is provided with an assembly hole 7, a first bolt 8 is provided in the assembly hole 7, and one end of the first bolt 8 passes through the assembly hole 7 and is threaded into the locking hole 6.

[0032] After the first half-ring 1 and the second half-ring 2 are positioned by the positioning block 5 and the positioning groove 12, the first bolt 8 is placed in the assembly hole 7 and the assembly hole 7 is screwed into the locking hole 6, which can fix the splicing of the first half-ring 1 and the second half-ring 2.

[0033] By using the matching structure of positioning grooves 12 at both ends of the first half-ring 1 and positioning blocks 5 at both ends of the second half-ring 2, the two outer ring components can be quickly and accurately aligned during splicing, effectively avoiding misalignment. Furthermore, by using the first bolt 8 to pass through the assembly hole 7 and threadedly connect to the locking hole 6, the connection strength at the splicing point of the outer ring is further strengthened, allowing the outer ring to form a stable annular structure, providing a reliable foundation for the overall operation of the bearing.

[0034] The inner ring includes an inner ring component 3, which has a receiving cavity. The inner ring component 3 has a cavity inside that is installed with the connecting shaft. This cavity can be designed with a keyway as needed.

[0035] In this embodiment, a ball bearing 11 arranged in a circumferential array is provided between the outer ring and the inner ring. The support mechanism 9 includes two first semi-arc frames 91 and two second semi-arc frames 92 and a connecting component. The two first semi-arc frames 91 and the two second semi-arc frames 92 are connected end to end to form a ring structure, and the two ring structures form a retainer through the connecting component. Each of the two first semi-arc frames 91 is provided with a first receiving groove 93, and each of the two second semi-arc frames 92 is provided with a second receiving groove 94. The ball bearing 11 is located between the first receiving groove 93 and the second receiving groove 94.

[0036] The ring structure formed by splicing two first semi-circular frames 91 and two second semi-circular frames 92 is then fixed between the first receiving groove 93 and the second receiving groove 94 by means of a connecting component, and the rolling ball 11 between the first receiving groove 93 and the second receiving groove 94 provides rolling support between the inner and outer rings.

[0037] In this embodiment, the connecting component includes a limiting screw tube 95 fixedly connected to the second semi-arc frame 92 and a limiting hole 96 opened on the first semi-arc frame 91, wherein the limiting screw tube 95 and the limiting hole 96 are matched.

[0038] In order to align the annular structure formed by the two first semi-arc frames 91 and the annular structure formed by the two second semi-arc frames 92, the limiting screw tube 95 can be inserted into the limiting hole 96, so that the first receiving groove 93 on the first semi-arc frame 91 and the second receiving groove 94 on the second semi-arc frame 92 are aligned.

[0039] By confining the ball bearing 11 between the first receiving groove 93 of the first semi-arc frame 91 and the second receiving groove 94 of the second semi-arc frame 92, and ensuring precise alignment of the grooves through the connecting components, the ball bearing is effectively prevented from falling out, ensuring smooth operation of the bearing. The outer ring and cage are both designed as separate units, combined with the detachable connection structure of bolts and groove blocks, which continues the advantage of separate bearings that do not require disassembly of the shaft or surrounding structure, making the installation, disassembly and maintenance process more convenient, and taking into account both reliability and ease of operation.

[0040] The connecting assembly also includes a second bolt 97, one end of which passes through the limiting hole 96 and is threaded into the limiting screw tube 95.

[0041] To further improve the stability of the connection between the first semi-arc frame 91 and the second semi-arc frame 92, the second bolt 97 is screwed into the limiting screw tube 95 to form a limiting component to limit the spliced ​​first semi-arc frame 91 and the second semi-arc frame 92.

[0042] By splicing two first semi-circular frames 91 and two second semi-circular frames 92 to form a ring cage, and then using the locking blocks of the first connecting slot block 98 and the second connecting slot block 99 to achieve a tight splicing between the semi-circular frames, the splicing gap is eliminated. Then, through the alignment and cooperation of the limiting screw tube 95 and the limiting hole 96 and the locking and fixing of the second bolt 97, the cage structure is made more stable, avoiding jamming or shaking during bearing operation, and significantly extending the service life of the bearing.

[0043] The first semi-circular frame 91 has a second connecting groove block 99 at both ends, and the second semi-circular frame 92 has a first connecting groove block 98 at both ends.

[0044] The second connecting slot 99 and the first connecting slot 98 have the same type of structure. The first connecting slot 98 and the second connecting slot 99 form a slot and a block structure at both ends of the first semi-arc frame 91 and the second semi-arc frame 92, respectively. The two first semi-arc frames 91 and the two second semi-arc frames 92 are spliced ​​together by means of the cooperation of the slots and blocks.
