Problems solved by technology

[0002] Bearing is an important part of contemporary mechanical equipment. Its main function is to support the mechanical rotating body, reduce the friction coefficient during its movement, and ensure its rotation accuracy. Rolling bearings are one of the bearings. Spherical alloy steel balls Installed in the middle of the inner steel ring and the outer steel ring, the friction force in the power transmission process is reduced and the mechanical power transmission efficiency is improved by rolling. The existing patent CN108591250A rolling bearing still has certain disadvantages in installation and use; the first , the outer ring bearing of the existing rolling bearing needs to be embedded in the mechanical parts for use, and it is inconvenient to fix the outer ring bearing and the mechanical parts; secondly, the inner ring bearing of the existing rolling bearing is connected with the transmission shaft Connecting and rotating, when the existing transmission shaft and the inner ring bearing are fixedly rotated, it is easy to loosen and produce idling phenomenon, which reduces the transmission efficiency; third, when the existing ball bearing is in use, its fine dust particles and impurities are easy to enter the ball At the connection with the bearing, the friction between the ball and the bearing is increased, which affects the rotation accuracy. For this reason, we propose a bearing assembly

Abstract

The present invention relates to the technical field of bearings, and a bearing assembly includes an outer ring bearing, wherein a limiting member is arranged on the outer surface of the side end of the outer ring bearing, and a fixing hole is embedded in the outer surface of the limiting member. The outer surface of the side end is provided with a hexagonal nut, the outer surface of the side end of the hexagonal nut is provided with a transmission shaft, the outer surface of the transmission shaft is embedded with a pin, the outer surface of the side end of the pin is provided with a fixing ring, the The inner outer surface of the outer ring bearing is embedded with a clamping groove, and the outer surface of the side end of the outer ring bearing is provided with balls. The bearing assembly can lock and fix the bearing and the mechanical parts through the cooperation of the outer hexagonal screw, the hexagonal nut and the limiter. Through the fitting of the bolt and the chute, there is no idle rotation of the drive shaft and the inner ring bearing. , Through the cooperation of the sealing ring, the movable half ring and the fixing screw, dust particles can be prevented from entering the connection between the ball and the bearing, and the rotation accuracy of the bearing can be guaranteed.
