Problems solved by technology

However, when the center distance is relatively small and the space is relatively small, if the end cover with this structure is used, one is that there is no place to drill bolt holes, and it is not easy to use bolts to fix it, and the other is that the space is small and oil leakage is easy. a big problem

Abstract

The invention discloses an embedded type end cover sealing structure which comprises a power output shaft and is characterized in that a bearing seat is arranged at one end of the power output shaft, and a bearing in contact with the power output shaft is arranged in the bearing seat. A sealing structure is arranged between the bearing seat and the power output shaft. An embedded end cover matched with the power output shaft is arranged in the bearing seat, and the sealing structure is arranged between the embedded end cover and the power output shaft. By means of the embedded type end cover sealing structure, an oil leakage condition is avoided effectively, and axial locating is achieved through the box body bearing seat, an embedded end cover stop opening and a power output shaft shoulder. In addition, the embedded type end cover sealing structure is simple and attractive in design, has a dual-sealing effect and effectively solves the problems of small space and oil leakage.

Description

technical field [0001] The invention relates to an embedded end cover sealing structure. Background technique [0002] The planetary reducer is a widely used industrial product. Its performance is comparable to other military-grade reducer products, but it has the price of industrial-grade products. It is mainly used for the slewing mechanism of tower cranes, and can also be used as a supporting component Lifting, excavation, transportation, construction and other industries. [0003] At present, the end caps used on the reducer are all positioned by the seams, and the bolts are closed. A certain space is required between the end caps to place and screw the bolts. However, when the center distance is relatively small and the space is relatively small, if the end cover with this structure is used, one is that there is no place to drill bolt holes, and it is not easy to use bolts to fix it, and the other is that the space is small and oil leakage is easy. A major drawback. ...
