Abstract
The utility model discloses a bearing dismounting device. A transparent cover is arranged on a shaft neck below a bearing. The bearing dismounting device comprises a press ring, a short lead screw, a first spindle sleeve, a long lead screw, a press cover, a stud and a second spindle sleeve. Each of the first spindle sleeve and the second spindle sleeve is formed by two half spindle sleeves that are connected with each other end to end. The internal diameter of each spindle sleeve matches that of a shaft neck of a grinding machine end cap. The external diameter of the press ring is equal to that of the transparent cover. Rims of both the press ring and the transparent cover are equipped with at least six concentric holes. The press cover is formed by a chassis and a cylindrical body that are welded together. The height of the cylindrical body is not smaller than the thickness of the bearing. The external diameter of the chassis is slightly smaller than that of the shaft neck of the grinding machine end cap. Upper surfaces of both the chassis and the shaft neck of the grinding machine end cap are provided with at least six concentric screwed holes. Two ends of each of the short lead screw and the long lead screw are of threaded structures. The first spindle sleeve and/or the second spindle sleeve are disposed between the transparent cover and the bearing. The first spindle sleeve and the second spindle sleeve are combined and welded through spot welding. The press ring or the press cover is arranged above the shaft neck of the grinding machine end cap. The press ring or the press cover is connected with the transparent cover through the short lead screw or the long lead screw by using lead screw nuts. The bearing dismounting device is simple in structure, low in manufacture cost and safe and reliable in dismounting, and will not damage bearings.
