The utility model discloses a self-aligning roller bearing, which comprises an outer ring, an inner ring, a cage, two rows of rollers and a sealing ring. The outer ring is sleeved outside the inner ring, the cage is arranged between the outer ring and the inner ring, the roller is arranged on the cage, the two ends of the outer ring are provided with outer ring ribs, the two ends of the inner ring are provided with inner ring ribs, the sealing ring comprises an annular plate, the outer edge of the annular plate is connected with the outer sealing lip, and the outer ring is sealed The sealing lip is connected with the outer ring flange, the inner edge of the annular plate is connected with the inner sealing lip, and the inner sealing lip is against the outer peripheral surface of the inner ring flange. The outer diameter of the inner ring flange gradually shrinks from the center of the inner ring to both ends of the inner ring, and an inclined surface is formed around the outer edge of the inner ring flange. The technical problem solved is that the self-aligning roller bearing in the prior art may damage the sealing ring and affect the service life of the bearing during the self-aligning. The inner sealing lip of the utility model is always close to the inner ring flange when the center is adjusted, and the sealing ring will not be squeezed by the inner ring flange at the same time, so the influence and damage of the sealing ring can be avoided when the center is adjusted, and the service life of the bearing is prolonged.
【技术实现步骤摘要】
调心滚子轴承
本技术涉及调心滚子轴承。
技术介绍
如图1和图2所示,现有技术中的调心滚子轴承在调心时,轴承内圈1偏转,轴承内圈1和轴承外圈2之间的距离缩小,密封圈3就会受到挤压,如果轴承内圈1偏转角度过大,则可能将密封圈3挤压变形,密封唇31破损,这将直接导致密封圈3失效,不仅会影响轴承的调心性能,还会降低轴承的可靠性缩短轴承的使用寿命。

鉴于
技术介绍
的不足,本技术是提供了调心滚子轴承,所要解决的技术问题是现有技术中的调心滚子轴承在调心时可能破坏密封圈、影响轴承使用寿命。为解决以上技术问题,本技术提供了如下技术方案:调心滚子轴承,包括外圈、内圈、保持架、两列滚子和密封圈,所述外圈套设在所述内圈外,所述保持架设置在所述外圈和所述内圈之间,所述滚子设置在保持架上,所述外圈两端设有外圈挡边,所述内圈两端设有内圈挡边,所述密封圈包括环形板,所述环形板的外边缘连接外密封唇,所述外密封唇连接所述外圈挡边,所述环形板的内边缘连接内密封唇,所述内密封唇抵贴所述内圈挡边外周面,所述内圈挡边外径由内圈中心向内圈两端逐渐缩小、在所述内圈挡边外周形成斜面。优选的,所述斜面上设有若干凹槽,所述凹槽底部连接有弹簧,所述弹簧顶端连接滚轮支架,所述滚轮支架上安装有滚轮,所述滚轮抵贴所述内密封唇。优选的,所述弹簧外套接有导向筒。优选的,所述外圈挡边上设有密封槽,所述外密封唇卡接在所述密封槽内。优选的,所述内密封唇呈“人”字形结构。本技术与现有技术相比所具有的有益效果是:在调心时,内密封唇始终贴合内圈挡边,同时密封圈不会受到内圈挡边的挤压力,因而能够避免调心时影响、破坏密封圈,延长了轴 ...
