Description

Technical Field

[0001] This utility model belongs to the technical field of snap-fit ​​deep groove ball bearings, and particularly relates to a snap-fit ​​deep groove ball bearing. Background Technology

[0002] Deep groove ball bearings are the most widely used type of rolling bearings. They mainly bear radial loads and can also bear a small amount of bidirectional axial loads. They have the characteristics of low friction coefficient, high limiting speed, full range of precision grades, and low manufacturing cost. They are suitable for a variety of installation scenarios and are widely used in motors, pumps, machine tools, automobiles and general machinery. They are one of the most versatile basic transmission components in industrial production.

[0003] Existing deep groove ball bearings have several drawbacks in use. For example, their assembly requires tools and machines, which are impractical in industrial equipment maintenance sites and field operations where large assembly equipment cannot be readily available. If on-site assembly is necessary, existing machine-based methods are completely unsuitable, requiring replacement of the entire bearing and increasing maintenance costs. Therefore, we propose a snap-fit ​​deep groove ball bearing. Utility Model Content

[0004] The purpose of this invention is to provide a snap-fit ​​deep groove ball bearing to solve the problems mentioned in the background art.

[0005] In view of this, the present invention provides a snap-fit ​​deep groove ball bearing, comprising an inner bushing, two cages, and a plurality of balls, and further comprising: An outer bushing is disposed on the periphery of an inner bushing, two retainers are located between the inner bushing and the outer bushing, and a plurality of balls are located between the two retainers; A first fixing ring is fixedly installed on the outer bushing and located on one side of a plurality of balls. A second fixing ring is inserted and installed on the outer bushing and located on the other side of the second fixing ring. The plurality of balls respectively contact the inner bushing, the first fixing ring and the second fixing ring. A plurality of fixing components, each of which is located on one of the retainers and is used to fix the positions of the two retainers; A limiting component is located on the outer bushing and is used to fix the position of the second fixing ring.

[0006] In this technical solution, the positions of the two cages can be fixed by the fixed components to ensure that several balls can be used stably. Then, the outer bushing is placed on one side of the inner bushing, and the second fixing ring is inserted into the outer bushing. The position of the second fixing ring can be fixed by the limiting components, which facilitates the assembly of the whole device and is simple to operate.

[0007] In the above technical solution, the fixing component further includes: A limiting post is inserted and installed on one of the retainers. One end of the limiting post passes through both retainers. A sliding groove is formed inside the limiting post, and a disc is rotatably installed in the sliding groove. Two guide grooves are formed on the disc, and guide posts are slidably installed in each of the two guide grooves. A limiting rod is fixedly installed at one end of each of the two guide posts. One end of each limiting rod passes through the sliding groove and extends to the outside, and both limiting rods are in contact with the other retainer. A handle is fixedly installed on the disc, and one end of the handle passes through the sliding groove and extends to the outside. A torsion spring is sleeved on the handle, and the handle is rotatably connected to the sliding groove. Both limiting rods are slidably connected to the sliding groove.

[0008] In this technical solution, rotating the handle forward causes the disc to rotate forward. The disc drives two guide posts to slide and move closer to each other through two guide grooves. At the same time, the torsion spring twists. When both limit rods slide to their limit positions, the limit posts are inserted into the two retainers. Then, the handle is released. Under the torsional force of the torsion spring, the handle and the disc rotate in opposite directions. The disc drives two guide posts to slide and move away from each other through two guide grooves. Finally, both limit rods contact the other retainer, which limits the position of the limit posts. Several limit posts can fix the position of the two retainers, ensuring that several balls can be used stably.

[0009] In the above technical solution, the limiting component further includes: A plurality of limiting grooves are provided, all of which are formed inside the outer bushing. A fixing block is inserted into each of the plurality of limiting grooves. Each of the fixing blocks is fixedly connected to a second fixing ring. A screw is threaded onto the outer bushing. One end of the screw passes through one of the fixing blocks, and the screw is threadedly connected to one of the fixing blocks.

[0010] In this technical solution, the outer bushing is placed on one side of the inner bushing, and then the second fixing ring is inserted into the outer bushing. The second fixing ring drives several fixing blocks to be inserted into several limiting grooves respectively. Then, the second fixing ring is rotated, and the second fixing ring drives several fixing blocks to rotate. When several fixing blocks are rotated to their limit positions, the operator uses a tool to turn the screw, and the screw will be inserted into one of the fixing blocks, which can fix the position of the second fixing ring, making it convenient to assemble the whole device and simple to operate.

[0011] In the above technical solution, further, the plurality of balls are distributed in a ring at equal intervals within the outer bushing, and both cages are in contact with the plurality of balls.

[0012] In this technical solution, it is ensured that all the balls can be used stably.

[0013] In the above technical solution, the inner bushing has an arc-shaped groove on its circumferential sidewall, and the cross-sections of the first fixing ring and the second fixing ring are both arc-shaped.

[0014] In this technical solution, the first fixing ring and the second fixing ring can limit the position of several balls to ensure stable use.

[0015] In the above technical solution, the second fixing ring and several fixing blocks are integrally formed.

[0016] In this technical solution, it is ensured that the second fixing ring and several fixing blocks can be used stably.

[0017] In the above technical solution, the cross-section of the limiting groove is L-shaped.

[0018] In this technical solution, the second fixing ring drives several fixing blocks to be inserted into several limiting grooves respectively, and then the second fixing ring is rotated, which drives the several fixing blocks to rotate.

[0019] The beneficial effects of this utility model are: This snap-fit ​​deep groove ball bearing, through the set fixing component, can fix the position of the two cages to ensure that several balls can be used stably. Then, the outer bushing is placed on one side of the inner bushing, and the second retaining ring is inserted into the outer bushing. Through the set limiting component, the position of the second retaining ring can be fixed, which facilitates the assembly of the whole device and is simple to operate. Attached Figure Description
