Description

Technical Field

[0001] The utility model relates to the field of bearings, in particular to a split precision bearing ring. Background Art

[0002] The bearing ring, also called the bearing outer ring, is one of the important components of the split bearing. The split bearing is a mechanical element that can reduce the friction between parts during relative motion of the machine, allowing the machine to move within a limited range, thereby extending the service life of the machine.

[0003] Existing bearings are generally installed by hammering the inner steel ring of the bearing using tools such as a hammer. However, the hammering method makes the bearing installation process complicated and time-consuming, and is prone to damage the bearing. Professional tools are also required for removal, which increases costs.

[0004] Therefore, it is necessary to provide a new split precision bearing ring to solve the above technical problems. Utility Model Content

The annular plate 6 is located inside the placement groove 7, and thermal grease is filled between the two annular plates 6. A plurality of heat dissipation fins 10 are fixed on the upper arc-shaped mounting seat 3. The thermal grease and the plurality of heat dissipation fins 10 can accelerate the heat dissipation speed of the bearing, thereby further increasing the service life of the bearing.

[0025] A first connecting seat 11 is fixed on both sides of the upper arc-shaped mounting seat 3, and a second connecting seat 12 is fixed on both sides of the lower arc-shaped mounting seat 4. The first connecting seat 11 and the second connecting seat 12 are fixedly connected by high-strength bolts 13. When the bearing is in use, the staff can place the two annular plates 6 on the outer ring 1 in the two placement grooves 7 on the lower arc-shaped mounting seat 4 respectively, and connect the two mounting seats together through high-strength bolts 13. Finally, the threaded end of the high-strength screw 9 is screwed into the threaded hole 8 on the outer ring 1 to complete the overall installation of the bearing. The operation is simple, convenient and stable. By setting two annular plates 6, the axial force exerted on the entire bearing can be resisted to prevent the bearing from detaching.

[0026] Two threaded holes 8 are arranged at intervals on the outer ring 1, and two high-strength screws 9 are arranged at intervals above the upper arc-shaped mounting seat 3.

The wear-resistant sealing gasket 17 contacts the surface of the inner ring 2 to prevent the lubricating oil from flowing out. When the wear-resistant sealing gasket 17 is damaged, the two separate semi-ring closing plates 15 can greatly facilitate its subsequent disassembly and replacement.
