The invention belongs to the technical field of crawler-type engineering machinery, and particularly relates to a self-lubricating deep groove ball bearing and a supporting chain wheel. A raceway of the self-lubricating deep groove ball bearing is filled with a lubricating medium, sealing rings are arranged between an inner ring and an outer ring, and the sealing rings are arranged on the two sides of the raceway and seal the raceway; an outer ring of the self-lubricating deep groove ball bearing is in interference fit with the wheel body, an inner ring of the self-lubricating deep groove ball bearing is in interference fit with the wheel shaft, and an airtight sealing piece does not need to be arranged between the wheel body and the wheel shaft. A lubricating medium does not need to be injected from the outside to lubricate the bearing; an airtight sealing piece on the supporting chain wheel and a screw plug structure for filling lubricating oil are omitted, so that the cost of raw materials is reduced; and in the assembly process of the supporting chain wheel, an airtight sealing piece does not need to be assembled, airtightness detection or unscrewing of a screw plug on an end cover to inject lubricating oil into a wheel body and the like does not need to be carried out, and the assembly efficiency is improved.
本发明属于履带式工程机械技术领域,尤其一种自润滑深沟球轴承和托链轮。本发明自润滑深沟球轴承所述滚道内填充有润滑介质,内圈和外圈之间设置有密封环,密封环设置在滚道两侧且密封滚道;自润滑深沟球轴承的外圈与轮体过盈配合,自润滑深沟球轴承的内圈与轮轴过盈配合,轮体与轮轴间无需设置气密性密封件。本申请不需要外界注入润滑介质进行轴承润滑;省去了托链轮上气密性密封件和加注润滑油用的螺塞结构,原材料成本降低;且托链轮的装配过程无需再装配气密性密封件,也无需再进行气密性检测或拧开端盖上螺塞向轮体内加注润滑油等,提高了装配效率。
