The invention discloses a roller cage shoe sealing structure and a roller cage shoe using the same, and relates to the technical field of vertical shaft lifting guiding, the roller cage shoe sealing structure comprises an annular groove sealing seat and a sealing cover with a U-shaped section, a sealing groove is formed in the peripheral wall of the annular groove sealing seat, a floating seal is arranged in the sealing groove, and the sealing cover is arranged on the periphery of the annular groove sealing seat in a buckled mode. The annular inner circumferential wall of the sealing cover is in contact with the periphery of the floating seal; a through hole matched with the main shaft is formed in the end part, far away from the roller, of the sealing cover; the roller rotates to drive the annular groove sealing seat to rotate, the floating seal can be affected by centrifugal force to be close to the sealing cover during rotation, sealing of a main shaft connector is achieved, the sealing effect is improved, meanwhile, a rotating part does not make direct contact with the main shaft, abrasion to the main shaft is reduced, and the service life is prolonged.
本发明公开一种滚轮罐耳密封结构及使用其的滚轮罐耳,涉及立井提升导向技术领域,包括:环形沟槽密封座以及截面呈U型的密封罩,环形沟槽密封座的外周壁上开设有密封槽,密封槽内设置有浮动密封,密封罩扣设在环形沟槽密封座外周,密封罩的环形内周壁与浮动密封外周接触,密封罩远离滚轮的端部开设与主轴相匹配的通孔;本发明中利用滚轮的转动带动环形沟槽密封座进行转动,转动时浮动密封会受到离心力的影响贴近密封罩,实现对主轴连接口处的密封,提高了密封效果,同时转动部分与主轴无直接接触,减少对主轴的磨损,提高使用寿命。
