Abstract
Description
Technical Field
[0001] This utility model relates to the field of bearings, and in particular to a novel bearing structure. Background Technology
[0002] Bearings are essential components in modern machinery. Their primary function is to support rotating parts, reduce friction during movement, and ensure rotational accuracy. The working principle of a bearing is based on the rolling of rolling elements between inner and outer rings to reduce friction between mechanical parts. The contact points between the rolling elements and the inner and outer rings are called the contact lines, and the pressure along these contact lines is crucial to the load capacity of the bearing. Bearings typically utilize cages to evenly distribute rolling motion between two rings. The shape, size, and number of cages directly affect the bearing's load capacity and performance.
[0003] In current practical applications of bearings, there is indeed a problem where the connection, contact area, and connection width between the inner ring of a bearing and the load are consistent. When the load increases, because the contact width is difficult to increase, the fit between the inner ring and the shaft determines the bearing's positioning, support method, and stability under load. Improper fit can not only affect the bearing's load-carrying capacity but may also lead to premature bearing failure or degraded equipment performance. With a consistent contact area and connection width, the stress on the bearing increases accordingly with the load. If the contact width cannot be increased, the bearing may experience relative slippage under heavy loads, leading to accelerated wear, reduced load-carrying capacity, and consequently, affecting the stability of the connection. Utility Model Content
[0004] The main objective of this invention is to provide a novel bearing structure that can effectively solve the problems mentioned in the background art.
[0005] To achieve the above objectives, the technical solution adopted by this utility model is as follows:
[0006] A novel bearing structure includes a bearing housing, a bearing inner housing, and bearing balls. The bearing inner housing is installed inside the bearing housing, and an inner cavity is formed between the bearing housing and the bearing inner housing. Multiple bearing balls are placed in the inner cavity. An inner channel is provided on the end face of the bearing inner housing for load insertion.
[0007] The inner channel has a sliding groove at the opening, and the groove wall of the sliding groove has a lateral limiting groove. An extended pushing block is embedded in the groove of the sliding groove, and the side wall of the extended pushing block has a limiting block that matches the lateral limiting groove. Pushing the extended pushing block increases the connection width between the bearing inner shell and the load, and enhances the connection stability.
[0008] The extended push block has an installation hole at its outer end, and the bottom of the sliding groove has a mating hole that matches the installation hole. Bolts are inserted into the installation hole and the mating hole to connect the extended push block to the bearing inner shell. Bolts are inserted into the installation hole to connect to the load, thereby improving the connection performance between the two.
[0009] As a preferred embodiment of this application, the side wall of the inner channel is provided with an annular groove communicating with the sliding groove. An anti-slip rubber ring is connected in the annular groove. The anti-slip rubber ring is connected to the bearing inner shell by an adhesive. The anti-slip rubber ring abuts against the limiting block in the lateral limiting groove and falls out. The width of the annular groove is the same as the width of the limiting block.
[0010] As a preferred embodiment of this application, a plurality of the sliding grooves are distributed in a ring on the inner channel, and the lateral limiting grooves of the sliding grooves are symmetrically distributed on the groove wall of the sliding grooves, with the edges of the lateral limiting grooves being arc-shaped.
[0011] As a preferred embodiment of this application, the extended push block and the limiting block are designed as a single unit, with two limiting blocks symmetrically distributed on the extended push block, and the limiting block, the extended push block and the bearing inner shell are designed to be smooth.
[0012] As a preferred embodiment of this application, the openings of the mating holes and mounting holes are designed in an arc shape, the mating holes are blind holes, and the mounting holes and mating holes are threaded holes;
[0013] As a preferred embodiment of this application, the edge of the extended push block is arc-shaped, and the inner wall of the extended push block is arc-shaped, consistent with the arc curvature of the inner channel.
[0014] Compared with the prior art, the present invention has the following beneficial effects:
[0015] Through specially designed internal channels, sliding grooves, extended push blocks, and limiting blocks, the connection width between the bearing inner housing and the load is effectively increased, significantly improving the stability of the connection. This design not only enhances the bearing's load-bearing capacity but also improves its stability and reliability under various operating conditions. The anti-slip rubber ring further enhances the structural robustness. It is tightly connected to the bearing inner housing, effectively preventing the extended push block and its limiting block from sliding or falling off during use, thus ensuring the normal operation and safety of the bearing.
[0016] The symmetrical distribution and arc-shaped design of the sliding and limiting grooves not only optimize the aesthetics of the structure but also significantly improve its durability and service life. This design effectively disperses stress, reduces local stress concentration, and lowers friction and wear, thereby enhancing the overall performance of the bearing. The load stabilizing mechanism is simple and quick to assemble and use, and easy to operate and maintain. Through standardized assembly procedures and clear instructions, users can easily install, debug, and maintain the bearings, further improving the reliability and stability of the equipment.

[0023] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the present utility model will be further described below in conjunction with specific embodiments.
[0024] like Figure 1 - Figure 5 As shown, a novel bearing structure is presented, which mainly consists of three core parts: a bearing housing 1, a bearing inner housing 2, and bearing balls 4. The bearing inner housing 2 is precisely installed inside the bearing housing 1, forming a closed inner cavity 3 between them. Multiple bearing balls 4 are arranged in an orderly manner within this inner cavity 3 to ensure the normal operation and load-bearing capacity of the bearing.
[0025] To facilitate load insertion, an inner channel 5 is specially designed on the end face of the bearing inner housing 2. A sliding groove 6 is further designed at the opening of the inner channel 5, and lateral limiting grooves 7 are formed on the groove walls of these sliding grooves 6. An extended push block 9 is embedded within the groove of the sliding groove 6, and its side wall has a limiting block 8 that matches the lateral limiting groove 7. By pushing the extended push block 9, the connection width between the bearing inner housing 2 and the load can be effectively increased, thereby enhancing the stability of the connection.
[0026] The extended push block 9 has mounting holes 10 at its outer end, while the bottom of the sliding groove 6 has mating holes 11 that match the mounting holes 10. By inserting bolts, a secure connection can be achieved between the extended push block 9 and the bearing inner housing 2. Simultaneously, the mounting holes 10 are used to insert bolts and connect to the load, further enhancing the connection performance between the two.
[0027] To prevent slippage or detachment during use, an annular groove communicating with the sliding groove 6 is provided on the side wall of the inner channel 5. An anti-slip rubber ring 12 is connected in this annular groove, tightly bonded to the bearing inner housing 2 by adhesive. The anti-slip rubber ring 12 serves to hold the limiting block 8 in the lateral limiting groove 7 in place, preventing it from falling out. The width of the annular groove is designed to perfectly match the width of the limiting block 8, ensuring both structural compactness and functionality.
[0028] Multiple sliding grooves 6 are arranged in a ring on the inner channel 5. This design is not only aesthetically pleasing but also evenly distributes the load, improving the bearing's load-bearing capacity. On the groove wall of each sliding groove 6, lateral limiting grooves 7 are symmetrically distributed, and the edges of the limiting grooves are designed with arcs to reduce stress concentration and improve the durability of the structure.
[0029] The extended push block 9 and the limiting block 8 are integrated into one unit, with the two limiting blocks 8 symmetrically distributed on the extended push block 9. This design not only simplifies the manufacturing process but also ensures smooth contact between the limiting block 8, the extended push block 9, and the bearing inner housing 2, reducing friction and wear.
[0030] Both the mating hole 11 and the mounting hole 10 feature an arc-shaped opening to enhance the strength and durability of the structure. The mating hole 11 is designed as a blind hole, while both the mounting hole 10 and the mating hole 11 are threaded holes. This design facilitates the installation and removal of bolts and also improves the reliability of the connection.
[0031] To further optimize bearing performance, the edges and inner walls of the extended push block 9 are designed with an arc shape, the curvature of which perfectly matches the arc curvature of the inner channel 5. This design is not only aesthetically pleasing but also effectively disperses stress, reduces local stress concentration, and thus improves the overall performance and service life of the bearing.
[0032] Assembly Process: The bearing inner housing 2 is precisely installed inside the bearing outer housing 1, ensuring a closed inner cavity 3 is formed between them. Multiple bearing balls 4 are arranged in an orderly manner within the inner cavity 3 to ensure normal bearing operation and load-bearing capacity. The extended push block 9 is embedded into the sliding groove 6, ensuring that the limiting block 8 on its side wall matches the lateral limiting groove 7 on the groove wall of the sliding groove 6. A mating hole 11 is provided at the bottom of the sliding groove 6, and the extended push block 9 is securely connected to the bearing inner housing 2 by inserting bolts. Mounting holes 10 are designed at the outer end of the extended push block 9, into which bolts are inserted and connected to the load to improve connection performance. An annular groove is opened on the side wall of the inner channel 5, and an anti-slip rubber ring 12 is connected therein. The anti-slip rubber ring 12 is ensured to be tightly connected to the bearing inner housing 2 with adhesive to prevent the limiting block 8 from falling out. All components are ensured to be correctly installed; the sliding grooves 6 are annularly distributed on the inner channel 5, and the lateral limiting grooves 7 on the groove wall of each sliding groove 6 are symmetrically distributed with arc-shaped edges. Inspect the integrated design of the extended push block 9 and the limit block 8 to ensure they are symmetrically distributed and in smooth contact. Ensure that the openings of the mating holes 11 and the mounting holes 10 are rounded to enhance structural strength and durability.
[0033] Usage Procedure: Insert the load into the inner channel 5 on the end face of the bearing inner housing 2. Increase the connection width between the bearing inner housing 2 and the load by pushing the extended push block 9, enhancing the stability of the connection. Ensure the connection between the extended push block 9 and the load is secure, and that the anti-slip rubber ring 12 abuts against the limiting block 8 in the lateral limiting groove 7 to prevent it from falling out. After confirming that all connections and components are installed correctly, begin operating the bearing. The bearing balls 4 roll orderly within the inner cavity 3, ensuring normal bearing operation and load-bearing capacity. Regularly monitor the bearing's operation, checking for abnormal noise, overheating, or vibration. If necessary, perform appropriate maintenance and adjustments to ensure long-term stable bearing operation.
