Bearing for transmission shaft

传动轴用轴承

Abstract

本实用新型涉及一种轴承,要解决的技术问题是传统的单列沟道轴承,钢球数目较少,轴承工作的平稳性较差,承受额定负荷能力较差,为解决上述问题,提供一种传动轴用轴承,包括内圈和外圈,所述内圈和外圈之间设置有两排用于安装钢球的沟道,沟道内设有钢球保持架,钢球设在钢球保持架内。本实用新型将传统的单列沟道轴承改变成双列沟道轴承,轴承的钢球数就会增加,从而增加轴承工作的平稳性,能够提高轴承承受额定负荷的能力,从而增加轴承的使用寿命。
The utility model relates to a bearing for a transmission shaft, aiming at solving the technical problems that the traditional single-row channel bearing is less in the number of steel balls, the bearing is poor in the working stability, and bad in supporting rated load capability. In order to solve the problem, the utility model provides a bearing for the transmission shaft. The bearing comprises an inner ring and an outer ring, two rows of channels for installing of steel balls are arranged between the inner ring and the outer ring, steel ball retainers are arranged in the channels, and the steel balls are arranged in the steel ball retainers. According to the bearing for the transmission shaft, the traditional single-row channel bearing is changed into the double-row channel bearing, the number of steel balls of the bearing can be increased, so that the working stationarity of the bearing can be enhanced, the capability of supporting rated load by the bearing can be improved, and the service life of the bearing can be prolonged.
