Description

Technical Field

[0001] This utility model relates to the field of deep groove ball bearing technology, and specifically to a deep groove ball bearing structure that prevents misalignment. Background Technology

[0002] Deep groove ball bearings are the most common type of rolling bearing. A basic deep groove ball bearing consists of an outer ring, an inner ring, a set of steel balls, and a cage. Deep groove ball bearings are available in single-row and double-row types. Deep groove ball bearings also come in two structures: sealed and open. Open bearings do not have a sealing structure. Sealed deep groove ball bearings are divided into dust seals and oil seals. The dust seal cover is made of stamped steel plate and only serves to prevent dust from entering the bearing raceway. The oil seal is a contact oil seal, which can effectively prevent grease from leaking out of the bearing.

[0003] Chinese patent CN221990775U discloses a deep groove ball bearing structure for preventing misalignment. It utilizes bolts and self-locking nuts to lock the entire mating cage, ensuring stable rolling of the balls within and around the inner and outer rings of the deep groove ball bearing. This prevents ball misalignment and extends the bearing's lifespan. Two roller carriers simultaneously guide the balls to the two mating cages, increasing overall bearing stability. A protective baffle also shields the bearing, providing a seal and preventing dust from entering.

[0004] In the above scheme, although the fitting cage is supported by a roller frame, the roller frame will have a limiting effect on the inner ring of the bearing during the process of supporting the fitting cage, which will cause inconvenience to the installation of the cage.

[0005] Therefore, this invention provides a deep groove ball bearing structure to prevent misalignment, in order to solve the above-mentioned problems. Utility Model Content

[0006] In order to overcome the defects of the prior art, this utility model provides a deep groove ball bearing structure to prevent misalignment, thereby solving the problem that the roller carrier will have a limiting effect on the inner ring of the bearing during the process of supporting and fitting the cage, which will cause inconvenience to the installation of the cage.

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

[0008] A deep groove ball bearing structure for preventing misalignment includes an outer ring and an inner ring, with an installation space between the outer and inner rings, and circumferentially arranged balls and a cage within the installation space.

[0009] The retainer body includes two splicing frames and a connecting mechanism. A support rod is fixedly connected to the splicing frame. A support groove is opened on the outer wall of the inner ring of the bearing, and one end of the support rod is inserted into the support groove.

[0010] Preferably, the splicing frame includes semi-circular frames arranged at equal intervals, and a connecting frame is provided between adjacent semi-circular frames, with both ends of the connecting frame fixedly connected to the two semi-circular frames respectively.

[0011] Preferably, the inner wall of the support groove is provided with an inclined groove, the support rod is inclined, and one side of the support rod abuts against the inclined groove.

[0012] Preferably, the connecting mechanism includes an internally threaded sleeve and a screw block. Both connecting frames have through holes. One end of the screw block is threaded to the internally threaded sleeve, and the connection between the screw block and the internally threaded sleeve is located inside the through hole.

[0013] Preferably, a stop block is fixedly connected to the internal threaded sleeve, and a threaded rod is fixedly connected to the screw block. The side of the stop block and the threaded rod that are close to each other are respectively abutted against the side of the two connecting frames that are far apart from each other.

[0014] Preferably, the inner wall of the outer ring of the bearing is provided with a second adapter groove, the outer wall of the inner ring of the bearing is provided with a first adapter groove, and the two ends of the ball are respectively slidably connected in the second adapter groove and the first adapter groove.

[0015] Preferably, the outer ring of the bearing has a mounting groove, and a dustproof ring is installed in the mounting groove.

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

[0017] 1. The retainer structure, formed by the splicing frame, support rod, and connecting mechanism, combined with the matching grooves on the inner and outer rings of the bearing, provides bidirectional ball restraint, significantly reducing the risk of ball misalignment during high-speed operation. The design of inserting the support rod into the non-through support groove and increasing the contact area with the inclined groove ensures support strength while reducing frictional resistance, allowing the balls to roll stably along the predetermined trajectory and avoiding local wear or jamming caused by misalignment, thereby extending the overall service life of the bearing.

[0018] 2. By adopting a split splicing frame and modular connection mechanism, during installation, you only need to position a single splicing frame close to the outer ring first, and then quickly lock the two halves of the structure through the internal threaded sleeve and screw block. The cooperation design of the stop block and threaded rod can automatically abut against the connecting frame body to complete self-alignment during the tightening process without the need for additional tools. Moreover, the two limit points of the non-through slot support groove further simplify the alignment steps, which greatly improves the assembly efficiency of the cage, and is especially suitable for mass production scenarios.

[0024] The following will refer to the attached reference. Figures 1 to 4 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.

[0025] A deep groove ball bearing structure for preventing misalignment includes an outer ring 1 and an inner ring 2. An installation space is provided between the outer ring 1 and the inner ring 2. The installation space contains circumferentially arranged balls 7 and a cage. To reduce friction of the balls 7 in the installation space, lubricating oil can be added to the installation space.

[0026] The retainer includes two splicing frames and a connecting mechanism. A support rod 10 is fixedly connected to the splicing frame. A support groove 11 is provided on the outer wall of the inner ring 2 of the bearing, and one end of the support rod 10 is inserted into the support groove 11.

[0027] When installing the splicing frame, it is necessary to first install the splicing frame close to the outer ring 1 of the bearing, and then insert the support rod 10 into the support groove 11 to complete the positioning of the splicing frame.

[0028] Moreover, the support groove 11 is a non-through groove, and there are two limiting points when the support rod 10 slides in the support groove 11.

[0029] In this embodiment, the splicing frame includes semi-circular frame bodies 8 arranged at equal intervals, and a connecting frame body 9 is provided between adjacent semi-circular frame bodies 8, with both ends of the connecting frame body 9 fixedly connected to the two semi-circular frame bodies 8 respectively.

[0030] The semi-circular frame 8 is semi-circular. When the two splicing frames are spliced, the two semi-circular frames 8 will form a ring structure to position the ball bearing 7, while the two connecting frames 9 will be close together to form a fixed position.

[0031] The inner wall of the support groove 11 is provided with an inclined groove, the support rod 10 is set at an angle, and one side of the support rod 10 is attached to the inclined groove. In order to increase the contact area between the support rod 10 and the support groove 11, the support rod 10 is installed in the support groove 11 through the inclined groove, which can ensure the support effect of the support rod 10 on the splicing frame.

[0032] In this embodiment, the connecting mechanism includes an internal threaded sleeve 13 and a screw block 16. Both connecting frames 9 are provided with through holes 12. One end of the screw block 16 is threaded to the internal threaded sleeve 13, and the connection between the screw block 16 and the internal threaded sleeve 13 is located inside the through hole 12.

[0033] When fixing the splicing frame, the screw block 16 can be inserted into the through hole 12, and the internal threaded sleeve 13 can be screwed onto the screw block 16 from another through hole 12 to complete the fixing of the two splicing frames.

[0034] Among them, a stop 14 is fixedly connected to the internal threaded sleeve 13, and a threaded rod 15 is fixedly connected to the screw block 16. The side of the stop 14 and the threaded rod 15 that are close to each other are respectively attached to the side of the two connecting frames 9 that are far apart from each other.

[0035] When the internal threaded sleeve 13 is screwed onto the screwing block 16, the stop block 14 on the internal threaded sleeve 13 and the threaded rod 15 on the screwing block 16 will abut against the two connecting frames 9 respectively, and the stop block 14 and the threaded rod 15 will be used to limit the position of the connecting frame 9.

[0036] The inner wall of the outer ring 1 of the bearing is provided with a second adapter groove 6, and the outer wall of the inner ring 2 of the bearing is provided with a first adapter groove 5. The two ends of the ball 7 are slidably connected in the second adapter groove 6 and the first adapter groove 5 respectively. The first adapter groove 5 and the second adapter groove 6 are used to limit the ball 7 installed in the installation space to prevent the ball 7 from sliding out of the installation space.

[0037] The bearing outer ring 1 has an installation groove 3, and a dustproof ring 4 is installed in the installation groove 3. By installing the dustproof ring 4 inside the installation groove 3, the dustproof ring 4 can shield the installation space and reduce the entry of debris or dust into the installation space.
