Special single-row deep groove ball bearing for guide wheel of automobile door

汽车门导轮专用单列深沟球轴承

Abstract

The utility model relates to a special single-row deep groove ball bearing for a guide wheel of an automobile door. The special single-row deep groove ball bearing comprises an outer ring, an inner ring, rolling bodies and a connecting mandrel, wherein a seal ring is fixed on the outer ring; and external circle plastic is arranged on the outer ring. The special single-row deep groove ball bearing is characterized by also comprising a retainer, wherein the inner ring is an integral inner ring; the rolling bodies are spherical rolling bodies which are uniformly distributed between the outer ring and the inner ring; the inner ring is installed and fixed through the connecting mandrel; and the spherical rolling bodies are uniformly spaced by the retainer. According to the special single-row deep groove ball bearing for the guide wheel of the automobile door, the original two separable inner rings are converted into one integral inner ring, and meanwhile, the ball bearing is changed from the original full balls without the retainer to full balls with the retainer. Therefore, the bearing can bear the corresponding load, the rotation resistance is reduced, and the bearing is less prone to abrasion in case of high-load application. When the bearing is arranged on the automobile door, the resistance is smaller than the original resistance during movement of the door, and the service life of the bearing is longer than that of the original bearing; and due to satisfactory matching, vibration or noise is avoided when an automobile runs at a high speed.
本实用新型涉及一种汽车门导轮专用单列深沟球轴承包括外圈、内圈、滚动体、连接芯轴;所述密封圈固定在外圈上面,外圆塑胶设置在外圈上;特征是:还包括保持架,所述内圈为整体式内圈,滚动体采用球型,均匀的分布设置在外圈和内圈之间,内圈通过连接芯轴安装固定,所述保持架将球形滚动体均匀的分开。本实用新型使原来的内圈由两个可分离转化为了一个整体内圈,同时原来满球无保持架改成了现在有保持架。该轴承不但可以承受相应的载荷,又降低了转动的阻力,轴承在高载荷使用下不容易磨损。轴承安装到汽车门上面,门移动的时候阻力比之前的小,轴承使用的寿命比之前延长,由于配合比较好,汽车高速运行时也不会产生振动和噪音。
