AI Technical Summary
Technical Problem
When existing thrust cylindrical roller bearings operate at high speeds, dust and impurities can easily enter the raceway surface, causing wear and seizure, affecting the normal operation of the bearings and potentially causing equipment failure.
Method used
A new type of thrust cylindrical roller bearing is designed. By setting a sealing plate, a pressure plate, a threaded ring and a positioning ring between the outer ring and the inner ring, a sealing strip is used to form a closed state to prevent dust and impurities from entering the bearing.
Benefits of technology
Effectively prevent dust and impurities from entering the bearing, reduce wear, avoid jamming, ensure the normal operation of the bearing, and reduce the risk of equipment failure.

Abstract
The utility model belongs to the technical field of thrust cylindrical roller bearings, and particularly relates to a novel thrust cylindrical roller bearing which comprises an outer ring, an inner ring is arranged in the outer ring, rotating grooves are formed in the outer walls of the two ends of the outer ring, threaded rings are connected to the outer walls of the two rotating grooves in a threaded mode, and positioning rings are fixedly connected to the outer walls of the threaded rings. The two rotating grooves are sleeved with moving rings, positioning grooves are formed in the outer walls of the moving rings, the positioning rings are located in the positioning grooves, the outer walls of the moving rings are fixedly connected with a plurality of connecting plates, the other ends of the connecting plates are fixedly connected with pressing plates, and sealing plates are arranged at the two ends of the outer ring. A plurality of through grooves are formed in the outer wall of the sealing plate. Under the action of the threaded ring and the movable ring, the interiors of the outer ring and the inner ring are in a closed state, and dust and impurities are prevented from entering the space between the outer ring and the inner ring to be accumulated to influence rotation of the bearing.
