[0002] Non-standard deep groove ball bearings are compared to standard deep groove ball bearings. Standard deep groove ball bearings have clear national or industry standards for dimensions, structure, precision, and performance. Non-standard deep groove ball bearings, on the other hand, do not meet these standard requirements and are custom-designed and manufactured to meet specific application requirements. Deep groove ball bearings with spline grooves are based on standard deep groove ball bearings, but with spline grooves machined into the outer or inner ring. Spline grooves are a circumferentially distributed keyway structure used to connect with other splined components to transmit torque.

[0003] In the existing technology, some new non-standard deep groove ball bearings with spline grooves are installed on the inner ring of the bearing with objects with spline grooves, and are used in conjunction with components with splines. However, when used in different processes, different components with splines need to be used, and most of them require replacing the entire bearing, which increases the long-term operating cost of the equipment. Especially in a production environment with frequent process switching, this cost increase will be more significant. Therefore, in response to the above shortcomings, a new non-standard deep groove ball bearing with spline grooves is proposed. Utility Model Content

[0022] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0023] Reference Figure 1 、 Figure 3 and Figure 4 The present invention provides an embodiment of a novel non-standard deep groove ball bearing with a spline groove, comprising an inner ring 1. The bottom end of the inner ring 1 is fixedly connected to the outer ring bottom shell 2. This fixed connection ensures the stability between the inner ring 1 and the outer ring bottom shell 2, laying the foundation for the entire bearing structure. The outer top end of the inner ring 1 is slidably connected to the outer ring top shell 3. This sliding connection allows the outer ring top shell 3 to move to a certain extent relative to the inner ring 1, providing the possibility for subsequent installation, disassembly, and maintenance operations.

[0024] The top of the inner ring 1 is internally slidably connected to a spline sleeve 4, which plays a key role in the entire bearing structure, especially in terms of cooperation with other splined components. The interior of the spline sleeve 4 is provided with a plurality of spline grooves 5, which are designed to precisely cooperate with the corresponding splined components, thereby achieving functions such as power transmission or positioning. The top of the inner ring 1 is provided with two sliding holes 6, which provide guidance and limiting functions for the movement of the spline sleeve 4. The outside of the spline sleeve 4 is fixedly connected to two clamping blocks 7, and the outside of the clamping blocks 7 is slidably connected to the inside of the sliding holes 6. This sliding connection between the clamping blocks 7 and the sliding holes 6 enables the spline sleeve 4 to stably perform linear sliding motion within a certain range, and ensures the directionality and accuracy of the spline sleeve 4 during movement;

[0025] The inner ring 1 is provided with a plurality of receiving holes 8, which are designed to accommodate other components and provide space for their movement. A sliding block 9 is slidably connected to the inner portion of the receiving hole 8. The sliding block 9 can slide up and down within the receiving hole 8. This sliding method allows the sliding block 9 to change its position according to the movement requirements of other components. The inner bottom end of the receiving hole 8 is fixedly connected to an elastic component for expansion and contraction. This elastic component is a key part of the entire structure, providing elastic restoring force for the movement and coordination between components. The elastic component includes a telescopic rod 10, the outer portion of which is sheathed with a strong spring 11. One end of the strong spring 11 is fixedly connected to the bottom end of the sliding block 9, and the other end of the strong spring 11 is fixedly connected to the inner bottom end of the receiving hole 8. This connection method allows the strong spring 11 to be compressed or stretched when the sliding block 9 moves, thereby storing or releasing elastic potential energy. The bottom end of the telescopic rod 10 is fixedly connected to the top end of the receiving hole 8, and the top end of the telescopic rod 10 is fixedly connected to the bottom end of the sliding block 9. The telescopic rod 10 works in conjunction with the strong spring 11 to provide elastic force while ensuring the linearity and stability of the movement of the sliding block 9;

[0026] The top of the sliding block 9 is fixedly connected to a top block 12, and the tops of multiple top blocks 12 are fixedly connected to a connecting ring 13. This connection method allows the top block 12 to transmit the movement of the sliding block 9 to the connecting ring 13. The bottom end of the clamping block 7 contacts the top of the connecting ring 13. When the clamping block 7 is subjected to external force, it can transmit the force to the connecting ring 13 through contact with the connecting ring 13, thereby affecting other components in the entire structure. A rotating hole 14 is opened inside the inner ring 1. The outer part of the clamping block 7 slides inside the rotating hole 14. This sliding connection allows the clamping block 7 to not only slide in a straight line, but also to rotate to a certain extent. The outer part of the connecting ring 13 also slides inside the rotating hole 14, which provides space and guidance for the movement of the clamping block 7 and the connecting ring 13. Two locking holes 15 are provided inside the inner ring 1. The outer side of one side of the clamping block 7 is engaged with the inner side of the clamping hole 15. The engagement relationship between the clamping block 7 and the clamping hole 15 is the key factor in fixing the position of the spline sleeve 4. When the clamping block 7 is engaged with the clamping hole 15, the spline sleeve 4 is fixed to the top of the inner ring 1, ensuring the stability of the entire structure during normal operation.

[0027] Reference Figure 1 、 Figure 2 and Figure 3 The inner ring 1 is movably connected to multiple steel balls 16. These balls 16 are a crucial component of the deep groove ball bearing. They roll between the inner and outer rings, reducing friction and supporting the load. Protective covers 17 are fixedly connected to the inner sides of both the outer ring bottom shell 2 and the outer ring top shell 3. These protect the bearing's internal components from external impacts, such as collisions and wear. A sealing ring 18 is fixedly connected to the inner side of protective cover 17. The interior of sealing ring 18 contacts the exterior of inner ring 1. This contact effectively prevents dust and impurities from entering the bearing, ensuring internal cleanliness and extending the service life of its components.

[0028] The outer ring bottom shell 2 is internally threaded at the top end, and a locking assembly is used to fix the outer ring bottom shell 2 and the outer ring top shell 3. The locking assembly is crucial for maintaining the tight connection between the outer ring bottom shell 2 and the outer ring top shell 3. The locking assembly includes a plurality of bolts 19, and each two bolts 19 are fixedly connected with an adapter block 20 on the same side. The design of the adapter block 20 allows the plurality of bolts 19 to form a whole, making it more convenient and coordinated to tighten or loosen the bolts 19. The outer threads of the top-end bolts 19 are connected to the bottom end of the outer ring top shell 3, and the outer threads of the bottom-end bolts 19 are connected to the top end of the outer ring bottom shell 2. By tightening the bolts 19, the outer ring bottom shell 2 and the outer ring top shell 3 can be tightly connected together, preventing them from loosening or separating during work. The outer ring bottom shell 2 and the outer ring top shell 3 are provided with a sealing ring 21 on the same side. The sealing ring 21 is made of butyl rubber, which has good oil resistance, wear resistance and sealing performance. The sealing ring 21 can further enhance the sealing performance between the outer ring bottom shell 2 and the outer ring top shell 3, preventing lubricating oil leakage or foreign matter from entering the bearing.

[0029] Working principle: When facing the need to replace the spline groove 5 component for different processes, first operate the spline sleeve 4. Press the spline sleeve 4, and the spline sleeve 4 will slide down along the inner end of the inner ring 1. The clamping block 7 on the outside of the spline sleeve 4 slides in the sliding hole 6 and the rotating hole 14, and the clamping block 7 extrudes the adapter ring 13 downward. The adapter ring 13 slides in the rotating hole 14 and transmits the pressure to the top block 12, which pushes the sliding block 9 to slide down in the accommodating hole 8. At this time, the strong spring 11 is compressed, and the telescopic rod 10 is retracted. When the clamping block 7 completely separates from the clamping hole 15, twist the spline sleeve 4 to make the clamping block 7 rotate in the rotating hole 14 to the appropriate position, and then the spline sleeve 4 can be removed from the top end of the inner ring 1. Then assemble the spline groove 5 component according to the opposite steps, align the spline sleeve 4 with the top end of the inner ring 1, and put it in. The clamping block 7 slides in the sliding hole 6 and the rotating hole 14 first, and when the clamping block 7 slides to the position corresponding to the clamping hole 15, the sliding block 9 pushes the top block 12 upward under the elastic force of the strong spring 11, and the top block 12 drives the adapter ring 13 to push the clamping block 7 upward, so that the clamping block 7 is clamped into the clamping hole 15, completing the replacement of the spline sleeve 4.

[0030] When lubricating the bearing, first apply oil to the outer ring bottom shell 2 and outer ring top shell 3. Tighten bolt 19. Since bolt 19 is connected by connector block 20 and threaded into outer ring bottom shell 2 and outer ring top shell 3, respectively, tightening bolt 19 will cause outer ring top shell 3 to move relative to outer ring bottom shell 2, separating the two. This releases seal ring 21. Then, remove seal ring 21 and apply oil through the gap created by the oiling hole. After lubrication, reinstall seal ring 21 to its original position between outer ring bottom shell 2 and outer ring top shell 3. Then, tighten bolt 19 again to secure the outer ring bottom shell 2 and outer ring top shell 3 securely. Seal ring 18 continues to seal, preventing foreign matter from entering the bearing and affecting the proper functioning of components such as steel balls 16. Throughout this operation, steel balls 16 within inner ring 1 provide support and reduce friction.

[0031] Finally, it should be noted that the above is only a preferred embodiment of the present invention and is not intended to limit the present invention. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art can still modify the technical solutions described in the aforementioned embodiments or make equivalent replacements for some of the technical features therein. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principles of the present invention should be included in the scope of protection of the present invention.
