The technical scheme adopted by the utility model is as follows:
a stepped hole is formed in the bearing end cover, and the stepped hole is a first hole and a second hole from inside to outside; the first hole is matched with the shaft, and the inner diameter of the second hole is smaller than that of the bearing seat 1; a plurality of connecting holes are uniformly formed in the bearing end cover along the circumferential direction, threaded holes are formed in opposite positions on the bearing seat, the bearing end cover and the bearing seat are fixedly connected through a connecting piece, the bearing end cover is provided with the threaded holes, and the oil injection nozzle is installed on and fastened to the threaded holes of the bearing end cover; the oil nozzle is disposed toward the second hole.
Furthermore, a first sealing groove is formed in the side wall of the first hole along the circumferential direction, a sealing ring is arranged in the first sealing groove, and the radial position where the bearing end cover is matched with the shaft is sealed.
Furthermore, a second sealing groove is formed in the bearing end cover on the second hole side along the circumferential direction, a sealing ring is arranged in the second sealing groove, and the matching position of the bearing end cover and the bearing seat in the axial direction is sealed.
Further, the material of sealing washer chooses the wool felt for use.
Furthermore, bearing end covers with oil injection nozzles are respectively arranged on two sides of the bearing seat, and the two sides of the bearing seat are sealed by the bearing end covers.
Furthermore, two sides of the bearing seat are respectively provided with a bearing end cover with an oil injection nozzle and a bearing end cover without the oil injection nozzle.
The utility model has the beneficial effects that:
the oiling bearing end cover that this application designed adopts between the bearing frame to dismantle and is connected, can make things convenient for the development of subsequent maintenance and maintenance work, sets up the oil nipple on the bearing end cover in addition, is convenient for to the interpolation of lubricated grease in the bearing left side, can avoid equipment operation because the bearing is lubricated badly and a series of problems that arouse.
