The utility model aims to solve the problems, and provides the bearing seat sealing structure, when the bearing seat is overhauled, the service condition of the bearing can be observed only by disassembling the annular transparent cover on the bearing seat sealing structure, the overhauling efficiency of the bearing seat is improved, and the sealing effect of the bearing seat is ensured.
The utility model solves the problems and adopts the technical scheme that:
a bearing seat sealing structure comprises a seat body; the main shaft is in interference fit with the inner side of the seat body; the annular sealing cover is in interference fit with the main shaft, the annular sealing cover is in sealing fit with the end face of the seat body, and a plurality of flanges are concentrically arranged on the upper part of one side of the annular sealing cover, which is far away from the end face of the seat body; the annular transparent cover is provided with a plurality of grooves which are in inserting fit connection with the flanges, the grooves in inserting fit connection and the flanges form a plurality of mutually communicated labyrinth seal structures, and the annular transparent cover is in sealing fit with the end face of the base body and is detachably connected with the base body; the annular fastening ring is in interference fit with the main shaft and is arranged at the lower part of one side of the annular sealing cover, which is far away from the end surface of the seat body; the annular sealing cover and the annular fastening ring are detachably connected with the base body.
Compared with the prior art, the utility model adopting the technical scheme has the outstanding characteristics that:
the bearing seat sealing structure changes the sealing structure of the bearing seat, when the bearing seat is overhauled, the service condition of the bearing can be observed only by disassembling the annular transparent cover on the sealing structure of the bearing seat, the bearing seat sealing structure is simple in structure and reasonable in design, the overhauling efficiency of the bearing seat is improved, and the sealing effect of the bearing seat is ensured.
Preferably, the further technical scheme of the utility model is as follows:
a plurality of gaps of the labyrinth seal structure are increased along the radial direction from the center of the circle to the outside; the sealing effect of guaranteeing the bearing seat through the structure arrangement prevents the sealing environment in the bearing seat from being damaged.
