Description

Technical Field

[0001] This utility model relates to the field of bearing technology, specifically to a universal cage and bearing for deep groove ball bearings and angular contact ball bearings. Background Technology

[0002] In the current industrial field, the design and manufacture of deep groove ball bearing cages is an important aspect of bearing technology. Currently, the most common deep groove ball bearing cages on the market mainly include two types: one is a double-riveted corrugated metal cage, and the other is a crown cage.

[0003] The wavy metal retainer, named for its distinctive wave shape, has a relatively complex manufacturing process, primarily relying on stamping for forming. During use, the assembly process is also relatively complex, requiring specialized riveting fixtures and a press. Furthermore, this type of retainer has limitations in dimensional accuracy, typically exhibiting poor precision. On the other hand, while the crown retainer features an open end, this design also results in lower overall strength. The uneven weight distribution across the two ends of the crown retainer can potentially cause imbalances during operation.

[0004] Furthermore, in existing rolling bearing technologies, deep groove ball bearings and angular contact ball bearings are often difficult to standardize, resulting in high costs for new product development and limiting the diversification and cost-effectiveness of bearing products. Utility Model Content

[0005] In view of this, the present invention provides a universal cage and bearing for deep groove ball bearings and angular contact ball bearings, which aims to solve the above-mentioned technical problems.

[0006] This utility model provides a universal cage for deep groove ball bearings and angular contact ball bearings, comprising:

[0007] The first single coronal retainer includes a first circumferential annular body and a plurality of first snap-fit ​​components disposed on the first circumferential annular body;

[0008] The second single coronal retainer includes a second circumferential annular body and a plurality of second snap-fit ​​components disposed on the second circumferential annular body;

[0009] The first single crown retainer and the second single crown retainer are assembled by the first snap-fit ​​assembly and the second snap-fit ​​assembly, and a rectangular space is formed between the two adjacent snap-fit ​​assemblies. The rectangular space is used to accommodate the rolling element of the bearing, and the rolling element is in contact with the inner side of the rectangular space.

[0010] In some embodiments of this application, the first snap-fit ​​component includes a plurality of alternately arranged first snap-fit ​​portions and first receiving portions, and the number of the first snap-fit ​​portions and the first receiving portions are equal.

[0011] In some embodiments of this application, the first snap-fit ​​portion is a convex tooth, the protruding top of the first snap-fit ​​portion is provided with a first locking claw, the first locking claw is an open cylindrical groove, and the protruding side of the first snap-fit ​​portion is an arc-shaped concave surface.

[0012] In some embodiments of this application, the first receiving portion is a cylindrical notched rib, and the size of the notched rib matches the cylindrical groove of the first locking claw.

[0013] In some embodiments of this application, the second snap-fit ​​component includes a plurality of alternately arranged second snap-fit ​​portions and second receiving portions, and the number of the second snap-fit ​​portions and the second receiving portions are equal.

[0014] In some embodiments of this application, the second latching portion is a convex tooth, the protruding top of the second latching portion is provided with a second locking claw, the second locking claw is an open cylindrical groove, and the protruding side of the second latching portion is an arc-shaped concave surface.

[0015] In some embodiments of this application, the second receiving portion is a cylindrical notched rib, and the size of the notched rib matches the cylindrical groove of the second locking claw.

[0016] In some embodiments of this application, the weights of the two end faces of the first single crown retainer and the second single crown retainer are the same after they are inserted and combined.

[0017] Compared with existing technologies, the beneficial effects of this utility model are as follows: the cage provided by this utility model, through the ingenious design of the snap-fit ​​and receiving parts, achieves a quick and stable combination of the first and second single-crown cages, which not only simplifies the installation process and improves assembly efficiency, but also ensures the stability and reliability of the cage structure. Simultaneously, the cage provided by this utility model is interchangeable between deep groove ball bearings and angular contact ball bearings, reducing bearing product development costs and shortening the product development cycle. Furthermore, the cage provided by this utility model is composed of two crown cages that are interlocked together, allowing for direct injection molding and a simple manufacturing process. During bearing assembly, manual snap-fit ​​is possible, eliminating the need for a specific press, simplifying the process. Moreover, the cage provided by this utility model, composed of two single-crown cages that are interlocked together, has symmetrical weight distribution at both ends, resulting in higher strength compared to single-crown cages and more stable cage operation during bearing use. Furthermore, the equal number and alternating arrangement of the snap-fit ​​and receiving parts make the cage structure more uniform, further improving the overall performance of the bearing. The design of the locking claws and notched ribs enhances the connection strength between the locking part and the receiving part, preventing the cage from loosening and falling off during operation, and improving the safety and reliability of the bearing.

[0018] The present invention provides a bearing, including the aforementioned universal cage for deep groove ball bearings and angular contact ball bearings, which has the same beneficial effects as the aforementioned universal cage for deep groove ball bearings and angular contact ball bearings, and will not be described in detail here.

[0027] Combination Figure 1-2 As shown, this embodiment provides a universal cage for deep groove ball bearings and angular contact ball bearings, comprising:

[0028] The first single coronal retainer 1 includes a first circumferential annular body and a plurality of first snap-fit ​​components disposed on the first circumferential annular body;

[0029] The second single coronal retainer 2 includes a second circumferential annular body and a plurality of second snap-fit ​​components disposed on the second circumferential annular body;

[0030] The first single crown retainer 1 and the second single crown retainer 2 are assembled by interlocking the first snap-fit ​​assembly and the second snap-fit ​​assembly. A rectangular space is formed between the two adjacent snap-fit ​​assemblies. The rectangular space is used to accommodate the rolling elements of the bearing, and the rolling elements are in contact with the inner side of the rectangular space.

[0031] Specifically, the cage provided in this embodiment is composed of two crown-shaped cages that interlock, and can be directly injection molded, simplifying the manufacturing process. During bearing assembly, the cage can be manually snapped together without the need for a specific press, simplifying the process. Furthermore, the cage provided by this invention is interchangeable between deep groove ball bearings and angular contact ball bearings, reducing bearing product development costs and shortening the product development cycle.

[0032] It is understood that in this embodiment, the design of the first single-crown cage 1 and the second single-crown cage 2, each cage including a circumferential annular body, a snap-fit ​​portion, and a receiving portion, simplifies the overall structure and facilitates production and assembly. The first single-crown cage 1 and the second single-crown cage 2, through the interlocking combination of the snap-fit ​​components, make the assembly process more convenient and faster, reducing the assembly time. The rectangular space formed between adjacent snap-fit ​​components is used to accommodate the rolling elements, making full use of the internal space of the cage and improving the bearing's load-bearing capacity and stability. The rolling elements contact the inner side of the rectangular space; this contact method effectively protects the rolling elements, reduces wear, extends the bearing's service life, and reduces friction during operation, thereby improving the bearing's operating efficiency and precision. Due to the versatility of the design, this cage can be applied to deep groove ball bearings and angular contact ball bearings, increasing the product's applicability and market competitiveness.

[0033] In one specific embodiment of this application, the first snap-fit ​​component includes a plurality of alternately arranged first snap-fit ​​portions 3 and first receiving portions 4, and the number of first snap-fit ​​portions 3 and first receiving portions 4 are equal.

[0034] Understandably, in this embodiment, by alternately arranging the first snap-fit ​​portion 3 and the first receiving portion 4, structural complementarity and functional synergy are achieved. This allows the first snap-fit ​​assembly to provide a more stable snap-fit ​​effect during connection, as the cooperation between the snap-fit ​​portion and the receiving portion increases the tightness and tensile strength of the connection. Furthermore, the equal number of snap-fit ​​portions and receiving portions ensures the uniformity and balance of the connection, thereby improving the stability and reliability of the overall structure. This design also helps simplify the assembly process, as each snap-fit ​​portion can find a corresponding receiving portion for connection, thus improving assembly efficiency and reducing the possibility of assembly errors.

[0035] Furthermore, the alternating arrangement of the first snap-fit ​​portion 3 and the first receiving portion 4 in this embodiment can improve the stability and load-bearing capacity of the structure, as they can support each other and distribute pressure. Secondly, the alternating arrangement helps to improve the flexibility and adaptability of the connection, allowing the snap-fit ​​portion and the receiving portion to better adapt to components of different sizes or shapes. In addition, the alternating arrangement of the snap-fit ​​portion and the receiving portion can simplify the assembly process and reduce the need for additional fasteners.

[0036] In one specific embodiment of this application, the first latching part 3 is a convex tooth, the top of the protrusion of the first latching part 3 is provided with a first locking claw 7, the first locking claw 7 is an open cylindrical groove, and the protrusion side of the first latching part 3 is an arc-shaped concave surface 9.

[0037] It is understood that in this embodiment, the first locking part 3 is a convex tooth, which provides stronger mechanical locking capability, ensuring a tight fit and stable connection with another component. Secondly, the shape of the convex tooth helps to disperse stress, reducing the risk of damage under pressure or impact. The first locking claw 7 at the protruding tip of the first locking part 3 is an open cylindrical groove, which effectively increases the contact area between the convex tooth and the mating component, thereby improving the stability and load-bearing capacity of the connection. The open cylindrical groove design allows the first locking claw 7 to undergo a certain elastic deformation when in contact with the mating component, thus achieving an adaptive locking effect and enhancing the reliability of the connection. Furthermore, the protruding side of the first locking part 3 is an arc-shaped concave surface 9, which helps to disperse stress and reduce stress concentration, thereby improving the durability and impact resistance of the connection. This provides a connection that is both stable and flexible, suitable for applications requiring frequent disassembly and installation.

[0038] In one specific embodiment of this application, the first receiving part 4 is a cylindrical notched rib, and the size of the notched rib matches the cylindrical groove of the first locking claw 7.

[0039] Understandably, in this embodiment, the first receiving part 4 is a cylindrical notched rib that matches the size of the cylindrical groove of the first locking claw 7. This ensures a good fit between the first locking claw 7 and the first receiving part 4, thereby improving the stability and reliability of the connection. Furthermore, the cylindrical notched rib structure may help disperse stress and reduce local stress concentration, thus improving the overall structure's durability and load-bearing capacity. This matching design allows for a quick and easy installation process while maintaining a secure connection.

[0040] In one specific embodiment of this application, the second snap-fit ​​component includes a plurality of alternately arranged second snap-fit ​​portions 5 and second receiving portions 6, and the number of second snap-fit ​​portions 5 and second receiving portions 6 is equal.

[0041] It is understood that this embodiment achieves structural complementarity and functional synergy through the alternating arrangement of the second snap-fit ​​portion 5 and the second receiving portion 6, thereby enhancing the stability and tensile strength of the connection. The equal number of snap-fit ​​portions and receiving portions ensures the uniformity and balance of the connection, improving the overall structural stability and reliability. Furthermore, the alternating arrangement of the second snap-fit ​​portion 5 and the second receiving portion 6 enhances the structural stability and load-bearing capacity. By mutually supporting and distributing pressure, it also improves the flexibility and adaptability of the connection, allowing the snap-fit ​​portion and receiving portion to adapt to components of different sizes or shapes.

[0042] In one specific embodiment of this application, the second latching part 5 is a convex tooth, the protruding top of the second latching part 5 is provided with a second locking claw 8, the second locking claw 8 is an open cylindrical groove, and the protruding side of the second latching part 5 is an arc-shaped concave surface 9.

[0043] Understandably, in this embodiment, the second locking part 5 adopts a convex tooth design, possessing strong mechanical locking capability to ensure a tight fit and stable connection with another component. The shape of the convex teeth helps to disperse stress and reduce the risk of damage. The second locking claw 8 is an open cylindrical groove, increasing the contact area and improving connection stability and load-bearing capacity. The groove design allows for elastic deformation, achieving self-adaptive locking and enhancing connection reliability. The arc-shaped concave surface 9 of the second locking part 5 helps to disperse stress, improve durability and impact resistance, and is suitable for occasions involving frequent disassembly and installation.

[0044] In one specific embodiment of this application, the second receiving part 6 is a cylindrical notched rib, and the size of the notched rib matches the cylindrical groove of the second locking claw 8.

[0045] Understandably, in this embodiment, the second receiving part 6 is a cylindrical notched rib that matches the size of the cylindrical groove of the second locking claw 8. This ensures a good fit between the first locking claw 7 and the first receiving part 4, thereby improving the stability and reliability of the connection. Furthermore, the cylindrical notched rib structure may help disperse stress and reduce local stress concentration, thus improving the overall structure's durability and load-bearing capacity. This matching design allows for a quick and easy installation process while maintaining a secure connection.

[0046] In one specific embodiment of this application, the weights of the two end faces are the same after the first single crown retainer 1 and the second single crown retainer 2 are inserted and combined.

[0047] Specifically, after the first single crown retainer 1 and the second single crown retainer 2 are inserted and combined, a rectangular space is formed between the first locking part 3 and the second locking part 5 of the first single crown retainer 1 and the second single crown retainer 2. Since the protruding side of the first locking part 3 and the second locking part 5 is an arc-shaped concave surface 9, the rolling element in the rectangular space is not easy to fall off, thus ensuring the stability of the device operation.

[0048] It is understood that in this embodiment, the first single-crown retainer 1 and the second single-crown retainer 2 are assembled with their end faces having the same weight. This ensures the balance of the retainers during use, reduces vibration and noise caused by uneven weight distribution, and improves the stability and service life of the equipment. Furthermore, the consistent weight of the end faces also helps improve assembly accuracy and ensures smooth operation of mechanical components.

[0049] Specifically, the working principle of the cage provided in this embodiment is as follows:

[0050] like Figure 2 As shown, a single-crown cage has an alternating array of notched ribs and axially protruding convex teeth on its circumferential ring, with an equal number of notched ribs and convex teeth. In actual bearing assembly, after the ball, inner ring, and outer ring are correctly positioned, two single-crown cages are interlocked to form a single assembly, as shown. Figure 1-2 As shown, during assembly, the convex teeth of one single-crown cage are aligned with the notched ribs of another single-crown cage, and the locking claws at the tips of the convex teeth engage the notched ribs. This cage can be used in both deep groove ball bearings and angular contact ball bearings. Example 2

[0051] This embodiment further provides a bearing, which is a deep groove ball bearing or an angular contact ball bearing, and the bearing in this embodiment includes the universal cage for deep groove ball bearings and angular contact ball bearings of Embodiment 1.
