The invention discloses a pitch-invariable crawler belt connecting assembly. The pitch-invariable crawler belt connecting assembly comprises a self-lubricating radial spherical plain bearing, an end plug dustproof sealing piece, a circlip for a hole, a track pin and a track pin lug, the track pin is installed in the track pin lug through the self-lubricating centripetal joint bearings at the two ends, one end of each self-lubricating centripetal joint bearing is axially positioned through an inner side shaft blocking structure on the track pin, and the other end of each self-lubricating centripetal joint bearing is axially positioned through a circlip for a hole. The circlip for the hole is arranged in a groove between the self-lubricating radial spherical plain bearing and the outer shaft stop structure; meanwhile, the two ends of the track pin lug are sealed through end plug dustproof sealing pieces, and the end plug dustproof sealing pieces are axially positioned through outer side shaft blocking structures. The pitch of the crawler belt connecting assembly is not changed.
本发明公开了一种不变节距的履带连接组件,包括自润滑向心关节轴承、端塞防尘密封件、孔用弹性挡圈、履带销及履带销耳;履带销通过两端的自润滑向心关节轴承安装在履带销耳内,且所述自润滑向心关节轴承一端通过履带销上的内侧轴挡结构进行轴向定位,另一端通过孔用弹性挡圈轴向定位,所述孔用弹性挡圈设置在自润滑向心关节轴承与外侧轴挡结构之间的凹槽内;同时履带销耳两端通过端塞防尘密封件实现密封,端塞防尘密封件通过外侧轴挡结构进行轴向定位。本发明履带节距不变。
