Abstract
Description
Technical Field
[0001] This utility model relates to the field of deep groove ball bearing technology, and more specifically to a deep groove ball bearing with high load-bearing capacity. Background Technology
[0002] Deep groove ball bearings are the most widely used type of rolling bearing. They are characterized by low frictional resistance and high speed, and can be used in components that bear radial loads or combined radial and axial loads, as well as components that bear axial loads. Examples include small-power electric motors, automotive and tractor gearboxes, machine tool gearboxes, and general machinery and tools. A typical deep groove ball bearing usually consists of an outer ring, an inner ring, several balls, and a cage. The cage spacers and guides the rollers. The raceways, formed by the recesses of the outer and inner rings, allow the balls to slide within them, creating a bearing structure that provides radial and axial rotational support.
[0003] For example, a deep groove ball bearing with prior art disclosure number CN220581496U includes a main module, which includes an inner ring, an outer ring disposed outside the inner ring, and steel balls arranged in a ring array between the inner ring and the outer ring.
[0004] However, the existing technology described above still has the following problems in use: the inner and outer rings are supported by multiple balls, resulting in a low load-bearing capacity for the entire deep groove ball bearing, which in turn affects its stability during use. Therefore, this invention provides a deep groove ball bearing with a high load-bearing capacity. Utility Model Content
[0005] To overcome the aforementioned deficiencies in the prior art, this utility model provides a deep groove ball bearing with high load-bearing capacity. By setting two cages between the inner and outer rings, and forming a double-row deep groove ball bearing with equally spaced balls in the two cages, the bearing has a wider width and can withstand greater radial loads. It can also withstand bidirectional axial loads, and its load-bearing capacity is higher than that of a single-row deep groove ball bearing. At the same time, the inner ring plate, the reinforcing plate, and the outer ring plate connect the inner and outer rings, which can further improve the overall load-bearing capacity of the deep groove ball bearing, thereby solving the problems mentioned in the background art.
[0006] To achieve the above objectives, this utility model provides the following technical solution: a deep groove ball bearing with high load-bearing capacity, comprising an outer ring and an inner ring, wherein two cages are provided between the outer ring and the inner ring, and multiple balls evenly distributed inside each cage are provided. Two raceways are machined on the inner wall of the outer ring and the outer wall of the inner ring, and the balls are disposed in the raceways. Reinforcing components are fixedly provided at both ends of the inner ring, and the reinforcing components include an inner ring plate fixed on the inner ring and an outer ring plate fixed on the outer ring. Multiple reinforcing plates are fixedly provided on the outer walls of the two inner ring plates, and a collar is provided on the inner wall of the two outer ring plates. The collar is detachably connected to the reinforcing plate.
[0007] In a preferred embodiment, the inner wall surfaces of both collars are machined with the same number of slots as the reinforcing plates, and the reinforcing plates are inserted into the slots to improve the connection strength between the reinforcing plates and the collars.
[0008] In a preferred embodiment, the outer walls of both collars are machined with a plurality of mounting holes arranged in a ring array, and each mounting hole is provided with a fastening bolt. The collars are fixed to a plurality of reinforcing plates by fastening bolts. The use of fastening bolts to connect the collars and the reinforcing plates facilitates the subsequent disassembly and replacement of the reinforcing plates and collars by the workers.
[0009] In a preferred embodiment, annular baffles are fixedly provided on the opposite sides of the two outer ring plates, and annular grooves are machined on the adjacent sides of the annular baffles and the outer ring plates. The collar is slidably disposed between the annular grooves. The annular baffles play a limiting role on the outside of the collar, which can improve the stability of the collar during rotation.
[0010] In a preferred embodiment, the retainer includes two detachable frames fixed together. Each frame has pockets on its adjacent side, the number of which is the same as the number of balls. The balls are placed in the pockets, and the pockets on the two frames are used to limit the movement of the balls, thereby improving the stability of the balls.
[0011] In a preferred embodiment, multiple positioning rods arranged in a circular array are fixedly provided at both ends of the inner ring and the outer ring. Positioning holes with the same number of positioning rods are machined on the side where the two inner ring plates are close to each other and on the side where the two outer ring plates are close to each other. The positioning rods are inserted into the positioning holes. With the positioning effect of the positioning rods, the inner ring plates and outer ring plates can be installed quickly, thereby improving the installation efficiency of the inner ring plates and outer ring plates.
[0012] The technical effects and advantages of this utility model are as follows:
[0013] 1. This utility model forms a double-row deep groove ball bearing by setting two cages between the inner and outer rings, and the balls in the two cages are evenly distributed to form a double-row deep groove ball bearing. Its width is wider, which can withstand greater radial loads, and it can also withstand bidirectional axial loads. Its load-bearing capacity is higher than that of a single-row deep groove ball bearing. At the same time, the inner ring plate, the reinforcing plate and the outer ring plate connect the inner and outer rings, which can further improve the overall load-bearing capacity of the deep groove ball bearing.
[0014] 2. The reinforcing plate and outer ring plate are connected by a collar. The collar can slide within the annular groove without affecting the normal rotation of the inner and outer rings. After removing the annular baffle, the collar and reinforcing plate can be easily disassembled, making the entire reinforcing assembly detachable for easy subsequent maintenance and replacement.

Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0024] Refer to the instruction manual appendix Figures 1-5 This utility model provides a deep groove ball bearing with high load-bearing capacity, including an outer ring 1 and an inner ring 2. Two cages 3 are provided between the outer ring 1 and the inner ring 2. Each cage 3 has a plurality of equally spaced balls 4 inside. Specifically, the cage 3 includes two detachable and fixed frame bodies 31. The two frame bodies 31 have pockets 32 with the same number of balls 4 on the side close to each other. The balls 4 are disposed in the pockets 32. The inner wall of the outer ring 1 and the outer wall of the inner ring 2 are both machined with two raceways 5. The balls 4 are disposed in the raceways 5.
[0025] The inner ring 2 is fixedly provided with reinforcement components 6 at both ends. The reinforcement components 6 include an inner ring plate 61 fixed on the inner ring 2 and an outer ring plate 62 fixed on the outer ring 1. Multiple reinforcement plates 63 are fixedly provided on the outer side walls of the two inner ring plates 61. The inner walls of the two outer ring plates 62 are provided with collars 64. The collars 64 are detachably connected to the reinforcement plates 63.
[0026] Furthermore, slots 65, the same number as the reinforcing plates 63, are machined on the inner wall surfaces of both collars 64. The reinforcing plates 63 are inserted into the slots 65. Multiple mounting holes 7 arranged in a ring array are machined on the outer walls of both collars 64. Each mounting hole 7 is equipped with a fastening bolt 8. The collars 64 are fixed to the multiple reinforcing plates 63 by the fastening bolts 8. The fastening bolts 8 are used to connect the collars 64 and the reinforcing plates 63, which facilitates the subsequent disassembly and replacement of the reinforcing plates 63 and collars 64 by the staff.
[0027] Annular baffles 9 are fixedly provided on the opposite side of the two outer ring plates 62. Annular grooves 10 are machined on the side of the annular baffles 9 and the outer ring plates 62 that are close to each other. The collar 64 is slidably disposed between the annular grooves 10. The annular baffles 9 play a limiting role on the outside of the collar 64, which can improve the stability of the collar 64 during rotation.
[0028] By setting two cages 3 between the inner ring 2 and the outer ring 1, and having balls 4 evenly distributed in the two cages 3 rolling in the raceway 5, a double-row deep groove ball bearing is formed. It has a wider width and can withstand greater radial loads, as well as bidirectional axial loads. Its load-bearing capacity is higher than that of a single-row deep groove ball bearing. At the same time, reinforcement components 6 are set on the front and rear sides of the deep groove ball bearing. The inner ring 2 and the outer ring 1 are connected by an inner ring plate 61, reinforcement plates 63 and an outer ring plate 62, which can further improve the overall load-bearing capacity of the deep groove ball bearing. The inner ring plate 61 and multiple reinforcement plates 63 are connected to the outer ring plate 62 by a collar 64. The collar 64 can slide in the annular groove 10 without affecting the normal rotation of the inner ring 2 and the outer ring 1.
[0029] In this embodiment, as Figures 3-5 As shown, multiple positioning rods 11 arranged in a circular array are fixed at both ends of the inner ring 2 and the outer ring 1.
