The invention provides a combined type sealing unit structure convenient to disassemble and assemble. The combined type sealing unit structure comprises a flange ring, a middle ring, a cover ring, an oil collecting ring, a lining, a clamping ring and a sealing ring combination. The flange ring, the middle ring, the cover ring and the oil collecting ring are sequentially connected and arranged on the lining in a sleeving mode. An annular boss is arranged at the end, close to the oil collecting ring, of the lining, and the distance between the annular boss and the oil collecting ring is d. The sealing ring combination comprises a first sealing ring and a second sealing ring; a first lip is arranged at the contact part of the first sealing ring and the bushing; a second lip is arranged at the contact part of the second sealing ring and the bushing; the distance d between the annular boss and the oil collecting ring is larger than the width of the first lip and the width of the second lip. After the sealing unit is used for a period of time, when it is detected that a certain scratch depth exists at the contact position of the lining and the sealing ring and the oil leakage amount is large, the lining can be moved towards the direction of the oil collecting ring by the width size of one first lip or the second lip, and the service life of the sealing unit can be prolonged to be more than two times that of a normal structure.
本发明提供了便于拆装的组合式密封单元结构,包括法兰圈、中间圈、盖圈、集油圈、衬套、卡紧圈和密封圈组合;法兰圈、中间圈、盖圈和集油圈依次连接,套设在衬套上;衬套上靠近集油圈的一端设置有环形凸台,环形凸台与集油圈间隔距离d;密封圈组合包括第一密封圈和第二密封圈,第一密封圈与衬套接触部设置第一唇;第二密封圈与衬套接触部设置第二唇;环形凸台与集油圈间隔距离d大于第一唇、第二唇的宽度;在使用了一段时间后,检查发现衬套与密封圈接触处有一定的划痕深度,漏油量大时,可以将衬套向集油圈方向移动一个第一唇或第二唇的宽度尺寸,可以实现延长密封单元的寿命至正常结构的两倍以上。
