A rotary storage type oil seal bearing

Abstract

The invention discloses a rotary accommodation type oil sealing bearing. The bearing comprises an outer ring and is characterized in that the outer ring is provided with rolling beads which are in axial array distribution, a maintaining frame is arranged above the rolling beads, a first inner ring is provided with a rolling ring, the rolling ring is fixed between the first inner ring and a secondinner ring, clamping oil sealing members are arranged on both sides of the outer ring, a threaded hole is formed in the outer ring, a threaded pin is arranged in the threaded hole, a balancing grooveis formed in the threaded pin, a balancing pin is arranged in the balancing groove, a first oblique pushing block is arranged on the top of the balancing pin, a pushing block hole which penetrates through the inner ring surface of the outer ring and is communicated with the threaded hole is formed in the outer ring, a clamping hole is formed in a clamping oil sealing member, a spring push plate isarranged in the clamping hole, a push head is arranged on the spring push plate, a push rod is arranged on the push head, a second oblique push block is arranged on the push rod, rolling bead grooveswhich are in array distribution are formed in the first inner ring, and a sliding groove is formed in the inner ring. The oil sealing bearing has the advantages that the oil sealing performance is strong, dust and water resisting functions of the bearing are enhanced, loads of the rolling bearings are shared by the rolling ring, and the overall loading capability of the bearing is improved.

Description

technical field [0001] The invention relates to the mechanical field, in particular to a rotary storage type oil seal bearing. Background technique [0002] Bearings are an important part of contemporary mechanical equipment. Its main function is to support the mechanical rotating body, reduce the friction coefficient during its motion, and ensure its rotation accuracy. Deep groove ball bearings are the most representative rolling bearings. Compared with other types of bearings with the same size, this type of bearings The friction coefficient is small, the limit speed is high, the structure is simple, the manufacturing cost is low, the precision is high, and the size range is large, and there are many forms. It is the most widely used type of bearing. It mainly bears radial loads, and can also bear certain axial loads, but it has a certain impact on the life of the bearings, and it is very inconvenient to maintain and change oil when used for high-depth drilling, and the l...

AI Technical Summary

Problems solved by technology

It mainly bears radial loads, and can also bear certain axial loads, but it has a certain impact on the life of the bearings, and it is very inconvenient to maintain and change oil when used for high-depth drilling, and the load capacity is low. In view of such situations as stuck, a rotary retractable oil-sealed bearing is proposed, which not only increases the bearing load, but also facilitates maintenance and has good sealing performance.
