The invention relates to a deep groove ball bearing with sealing rings on both sides, which solves the problem that the sealing rings of the existing deep groove ball bearings with sealing rings on both sides are easy to fall off under high temperature, high speed and heavy load conditions and cause poor lubrication. The invention comprises an inner ring, an outer ring, a sealing ring, a rivet, a steel ball and two half cages, each of which is provided with a raceway matching the steel ball, the outer ring is on the inner ring, and two half cages are arranged between the outer ring and the inner ring. The two half cages are fixed by rivets, and the pocket holes of the cage are provided with steel balls. A symmetrical inward concave arc is arranged at the intersection of the outer diameter and the two ends, and a symmetrical hook-shaped ring groove is arranged at the positions adjacent to the two ends of the inner side of the outer ring. The side of the ring groove is at an angle to the radial plane. A sealing ring matching the ring groove is arranged on each of the ring grooves, and the interference fit between the ring groove and the sealing ring is provided. The inner diameter of the sealing ring is closely related to the arc. The invention is applicable to the condition of radial force loading on the shaft.

一种两面带密封圈的深沟球轴承
本专利技术涉及一种轴承,具体涉及一种两面带密封圈的深沟球轴承。
技术介绍
传统的两面带密封圈的深沟球轴承的密封装置均采用轴向紧固密封,在高温、高速、重载等工况下使用易发生密封圈脱落现象,导致轴承润滑不良的故障。
技术实现思路
本专利技术为了解决现有的两面带密封圈的深沟球轴承在高温、高速和重载工况下容易发生密封圈脱落而造成润滑不良的问题,而提供一种两面带密封圈的深沟球轴承。本专利技术为解决上述技术问题采取的技术方案是:它包括内圈、外圈、密封圈、钢球和两个半保持架,外圈和内圈各设有与钢球相匹配的滚道,外圈套在内圈上,外圈和内圈之间设有两个半保持架,两个半保持架固定在一起,保持架的兜孔中设有钢球,所述内圈的外周面与两端面相交处设有对称的向内凹的圆弧,外圈里侧邻近两端的位置设有对称的钩形环槽,钩形环槽的侧面与外圈的端面成一定角度,所述钩形环槽与所述圆弧之间布置有密封圈,且钩形环槽与密封圈相匹配且二者之间过盈配合,密封圈的内径与所述圆弧紧贴。本专利技术与现有技术相比具有以下有益效果:一、本专利技术所述内圈的外周面与两端面相交处设有对称的向内凹的圆弧 ...
