Abstract

This utility model discloses an auxiliary support structure for a bearing cage with rolling element limiting, including an inner ring and an outer ring corresponding to the inner ring on the outside, with a cage placed between the inner and outer rings. The outer sides of the baffles at the upper and lower ends of the cage in this auxiliary support structure for rolling element limiting are inclined structures, and the first ball and the cage form a rotating structure. This protects the cage and the first ball through the baffles at both ends of the cage and their inclined structures, thereby ensuring the overall working stability of the cage. The cage of this device forms a locking and limiting structure with the inner and outer rings through a fixed plate, a locking rod, and a sliding rod. The sliding rod, through a second ball inserted into a groove, forms a rotating structure with the inner and outer rings. The fixed plate and its related components connect the cage to the inner and outer rings to ensure the support of the cage itself during operation, further ensuring the stability of the first ball during operation.

Description

Technical Field

[0001] This utility model relates to the field of bearing technology, specifically to an auxiliary support structure for bearing cages that limits the movement of rolling elements. Background Technology

[0002] Roller element positioning is a crucial function in rolling bearings, primarily achieved through the arrangement of the rolling elements and the design of the cage. The rolling elements (such as steel balls, cylindrical rollers, tapered rollers, and needle rollers) roll between the inner and outer rings of the bearing, providing support and transmitting loads. During operation, to ensure the even distribution of the balls and guarantee their normal rotation while preventing collisions, a cage is used to provide auxiliary support for the balls.

[0003] During operation, the bearing cage uses a ball bearing mechanism to evenly distribute the load among the balls, reducing friction and wear and maintaining bearing stability. However, existing bearing cages are susceptible to damage from dust and other impurities in the working environment, which can affect their normal operation. Furthermore, the cages themselves exhibit low stability during use. Therefore, this paper proposes an auxiliary support structure for the bearing cage with rolling element limiting to address these issues. Utility Model Content

[0004] The purpose of this utility model is to provide an auxiliary support structure for a bearing cage with rolling element limiting, so as to solve the problems mentioned in the background art, where dust and other impurities in the working environment can easily affect the normal operation of the existing bearing cage during use, and the cage itself has low support stability during use.

[0005] To achieve the above objectives, the present invention provides the following technical solution: a bearing cage auxiliary support structure for limiting rolling elements, comprising an inner ring, an outer ring corresponding to the outer side of the inner ring, and a cage placed between the inner ring and the outer ring, wherein multiple sets of first balls are embedded in the cage, and baffles are respectively provided at the upper and lower ends of the cage;

[0006] The baffle is provided with fixed plates on both sides, and the fixed plates are provided with locking rods on opposite sides on the side of the baffle, and the locking rods are inserted into the baffle. The outer side of the fixed plates is provided with sliding rods on opposite sides, and the other end of the sliding rods is embedded with second balls. The inner ring and outer ring are provided with sliding grooves at the upper and lower ends, and the sliding rods are inserted into the sliding grooves.

[0007] The baffle is provided with rubber pads on the top and bottom, and the rubber pads are provided with locking blocks on opposite sides. The locking blocks are inserted into the fixing plate. Multiple sets of bolts are inserted into the rubber pads, and the other ends of the bolts are screwed into the baffle.

[0008] Preferably, the outer sides of the baffles at the upper and lower ends of the cage are inclined structures, and the first ball and the cage form a rotating structure.

[0009] Preferably, the retainer forms an engagement and limiting structure with the inner and outer rings through a fixed plate, a locking rod, and a sliding rod, and the sliding rod forms a rotation structure with the inner and outer rings through a second ball inserted into the sliding groove.

[0010] Preferably, the rubber pad is connected to the baffle to form a spiral locking structure by bolts, and the rubber pad is connected to the fixing plate to form a locking and limiting structure by the locking block.

[0011] Compared with the prior art, the beneficial effects of this utility model are as follows: the outer sides of the baffles at the upper and lower ends of the bearing cage auxiliary support structure for rolling element limiting are both inclined structures, and the first ball and the cage form a rotating structure. Thus, the baffles at both ends of the cage and their inclined structures protect the cage and the first ball, thereby ensuring the overall working stability of the cage. The cage of this device forms a locking and limiting structure with the inner and outer rings through a fixed plate, a locking rod, a sliding rod, and the second ball passing through the sliding groove to form a rotating structure with the inner and outer rings. Thus, the fixed plate and its related components connect the cage with the inner and outer rings to ensure the support of the cage itself during operation, and further ensure the stability of the first ball during operation. The rubber pad of this device forms a spiral locking structure with the baffle through bolts, and the rubber pad forms a locking and limiting structure with the fixed plate through a locking block. Thus, the spirally installed rubber pad ensures the stability of the fixed plate assembly while providing shock absorption and protection for the upper and lower ends of the cage.

[0017] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. 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.

[0018] Please see Figure 1-4 This utility model provides a technical solution: a bearing cage auxiliary support structure for limiting rolling elements, including an inner ring 1, an outer ring 2 corresponding to the outer side of the inner ring 1, and a cage 4 placed between the inner ring 1 and the outer ring 2. Multiple sets of first balls 3 are embedded in the cage 4, and baffles are provided at the upper and lower ends of the cage 4.

[0019] Furthermore, the outer sides of the baffles at the upper and lower ends of the cage 4 are inclined structures, and the first ball 3 and the cage 4 form a rotating structure. Thus, the baffles can protect the entire cage 4, thereby reducing the impact of dust and other impurities on the cage 4.

[0020] The baffle is provided with a fixing plate 5 on both sides, and the fixing plate 5 is provided with a locking rod 6 on the opposite side of the side of the baffle. The locking rod 6 is inserted into the baffle. The outer side of the fixing plate 5 is provided with a sliding rod 7 on the opposite side. The other end of the sliding rod 7 is embedded with a second ball 8. The inner ring 1 and the outer ring 2 are provided with sliding grooves at the upper and lower ends, and the sliding rod 7 is inserted into the sliding groove.

[0021] Furthermore, the cage 4 forms a locking and limiting structure with the inner ring 1 and the outer ring 2 through the fixing plate 5, the locking rod 6, and the sliding rod 7. The sliding rod 7 forms a rotating structure with the inner ring 1 and the outer ring 2 through the second ball 8 inserted in the sliding groove. Thus, the locking rod 6 and the sliding rod 7 connect the inner ring 1 and the outer ring 2 without affecting the normal operation of the cage 4, so as to increase the support of the cage 4 when it is working.

[0022] The baffle is provided with rubber pads 9 on the top and bottom, and the rubber pads 9 are provided with locking blocks 11 on opposite sides. The locking blocks 11 are respectively inserted into the fixing plate 5. Multiple sets of bolts 10 are inserted into the rubber pads 9, and the other end of the bolts 10 are respectively screwed into the baffle. It should be noted that this utility model is an auxiliary support structure for a bearing cage for limiting rolling elements. All components are standard parts or components known to those skilled in the art. Its structure and principle can be learned by those skilled in the art through technical manuals or conventional experimental methods.

[0023] Furthermore, the rubber pad 9 forms a spiral locking structure with the baffle through the bolt 10, and the rubber pad 9 forms a locking and limiting structure with the fixing plate 5 through the locking block 11. Thus, the rubber pad 9 is spirally installed through the bolt 10, so that the stability of the fixing plate 5 during operation can be increased by the rubber pad 9 and the locking block 11, while the rubber pad 9 can provide auxiliary shock absorption and protection for the entire cage 4.

[0024] Working Principle: Using the rolling element limiting bearing cage auxiliary support structure, firstly, a fixed plate 5 is placed on the upper and lower ends of the cage 4, and a locking rod 6 is inserted into the baffle on the cage 4. Simultaneously, a sliding rod 7 is inserted into the sliding grooves on the inner ring 1 and outer ring 2. This increases the connection between the cage 4 and the inner and outer rings 1 and 2 through the fixed plate 5 and its related components. The second ball bearing 8 prevents interference with the normal operation of the cage 4. Then, rubber pads 9 are placed at both ends of the cage 4, and locking blocks 11 are inserted into the fixed plate 5. The rubber pads 9 engage and limit the fixed plate 5 and its related components, and also provide auxiliary shock absorption at the upper and lower ends of the cage 4, further ensuring the stability of the entire cage assembly. During normal use, the baffles at both ends and the inclined structure of the baffle edges further protect the cage 4, preventing dust and other impurities in the working environment from affecting its operation. This is the usage process of the rolling element limiting bearing cage auxiliary support structure.

[0025] Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features.
