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.
[0026] Please see Figures 1-6A drive shaft support bearing includes an outer bearing ring 1, a heat dissipation groove 2 on the outer side of the outer bearing ring 1, a heat dissipation fin 3 embedded inside the heat dissipation groove 2, a lubrication groove 4 on the inner side of the outer bearing ring 1, balls 5 inside the outer bearing ring 1, an inner bearing ring 6 inside the outer bearing ring 1, a sealing mechanism 7 on the outer side of the outer bearing ring 1, and a drive shaft body 8 inside the inner bearing ring 6. The sealing mechanism 7 includes a clamping device and a releasing device. The releasing device moves to drive the clamping device to release the bearing and pull it out for adjustment.
[0027] In this embodiment, the clamping device includes a bearing base 701. The top of the bearing base 701 has a placement groove 705, and the top of the bearing base 701 has a connecting seat 706. The bottom of the connecting seat 706 has an installation groove 707, and a connecting member 708 is fixedly installed on the bottom of the connecting seat 706. The inner diameter of the bearing base 701 is the same as the inner diameter of the connecting seat 706. The placement groove 705 and the installation groove 707 are the same size. Two identical connecting members 708 are provided, and the two connecting members 708 are symmetrically distributed about the vertical center line of the connecting seat 706. By providing the clamping device, the two sets of connecting members 708 at the bottom of the connecting seat 706 are tightly fitted with the two sets of limiting grooves 704 at the top of the bearing base 701. Because the connecting members 708 are flexible and resilient, the connecting seat 706 and the bearing base 701 are tightly connected, improving the overall stability and reliability. At the same time, the installation groove 707 and the placement groove 705 ensure accurate positioning of each component during installation.
[0028] Furthermore, the release device includes a push button 703. A through hole 702 is provided on the outer side of the bearing base 701, and the push button 703 is located inside the bearing base 701. A limiting groove 704 is provided on the top of the bearing base 701. The through hole 702 is adapted to the push button 703. Two identical through holes 702 and push buttons 703 are provided, and the two through holes 702 and push buttons 703 are symmetrically distributed about the vertical center line of the bearing base 701. With this release device, the two sets of push buttons 703 move through the limiting of the through holes 702, and simultaneously cooperate with the two sets of connecting parts 708. The bottom of the push button 703 is designed with a smooth layer structure, so that when the push button 703 presses against the connecting part 708, the connecting seat 706 can be smoothly pulled out, facilitating disassembly and installation, and offering high practicality.
[0029] Furthermore, the limiting groove 704 is adapted to the connector 708, which has a flexible and spring-loaded structure, and the bottom of the push button 703 has a smooth layer structure. By making the connector 708 flexible and spring-loaded, the connecting seat 706 and the bearing base 701 are tightly connected, improving the overall stability and reliability. At the same time, the smooth layer structure at the bottom of the push button 703 allows the connecting seat 706 to be smoothly pulled out when the push button 703 presses the connector 708, facilitating disassembly and installation and making it highly practical.
[0030] Furthermore, multiple identical heat dissipation grooves 2 are provided, arranged in a ring on the outer side of the bearing outer ring 1. Multiple identical heat sinks 3 are also provided, each corresponding to and fitting one-to-one with a heat dissipation groove 2. By providing multiple heat dissipation grooves 2 and heat sinks 3, with the heat sinks 3 embedded inside the heat dissipation grooves 2, the overall stability is improved, and the heat dissipation performance of the bearing is enhanced. This effectively reduces the temperature rise of the bearing during high-speed operation and extends the bearing's service life.
[0031] In addition, multiple identical balls 5 are provided, located between the outer ring 1 and the inner ring 6 of the bearing, and inside the lubrication groove 4. By providing multiple balls 5, they roll between the inner and outer rings, and lubricating grease forms a lubricating film on the contact surface between the balls 5 and the raceway, greatly reducing frictional resistance, wear, and energy loss, and ensuring smooth and efficient operation of the drive shaft.
[0032] It is worth noting that the inner ring 6 of the bearing is interference-fitted with the drive shaft body 8, and the diameter of the drive shaft body 8 is larger than the inner diameter of the inner ring 6 of the bearing. By setting the inner ring 6 of the bearing to be interference-fitted with the drive shaft body 8, the inner ring of the bearing is tightly fitted onto the shaft, becoming a single unit. The outer ring 1 of the bearing and the shaft achieve low-friction rotation through the rolling of the balls 5, which improves the overall reliability and practicality.
[0033] During use, the operator first checks each part for damage, inspecting all components to ensure that the outer bearing ring 1, inner bearing ring 6, balls 5, heat sink 3, and sealing mechanism 7 are undamaged, defect-free, and clean. Appropriate installation tools are prepared, and any problems are addressed and resolved promptly. After resolution, the operator proceeds to the next step. The inner bearing ring 6 is then fitted onto the drive shaft body 8, ensuring a tight fit and accurate positioning of the inner bearing ring 6, with its axis coinciding with the axis of the drive shaft body 8. This lays the foundation for the subsequent installation of the balls 5 and the smooth operation of the entire bearing. Next, the operator evenly places the balls 5 between the inner bearing ring 6 and the outer bearing ring 1. The number and specifications of the balls 5 depend on the bearing design requirements. During placement, the balls 5 must be neatly arranged, evenly spaced, and able to roll freely between the inner and outer rings to achieve good support and rotational function. Finally, the operator fits the outer bearing ring 1, with its heat dissipation grooves 2 and heat sink 3, onto the ring with the placed balls 5. Structurally, during installation, it is essential to ensure full contact between the bearing outer ring 1 and the balls 5, and to guarantee that the heat dissipation groove 2 and heat sink 3 are in the appropriate positions for effective heat dissipation. At this point, the operator ensures that the two sets of connecting parts 708 at the bottom of the connecting seat 706 are tightly fitted with the two sets of limiting grooves 704 at the top of the bearing base 701. Because the connecting parts 708 are flexible and resilient, a tight connection is achieved between the connecting seat 706 and the bearing base 701, improving overall stability and reliability. Simultaneously, the mounting groove 707 and the placement groove 70... 5. This ensures precise positioning of each component during installation. The two sets of push buttons 703 move through the limiting through holes 702 and cooperate with the two sets of connectors 708. The bottom of the push button 703 is designed with a smooth layer structure, so that when the push button 703 presses the connector 708, the connector 706 can be pulled out smoothly, which is convenient for disassembly and installation. If the staff needs to disassemble and replace the whole, they only need to reverse the above process to disassemble the whole and replace the damaged parts. The operation is simple and convenient.
