Detailed Description

As shown in fig. 1 to 4, the bearing dismounting device provided by the present invention includes a fixed plate 1, a dismounting plate 4 and a separate hydraulic jack 5, wherein the separate hydraulic jack 5 includes a jack main body 51 and a hydraulic pump 52, and the hydraulic pump 52 is connected to the jack main body 51 through an oil pipe; the fixed plate 1 and the disassembly plate 4 are connected by a pull rod 3, the bottoms of the fixed plate 1 and the disassembly plate 4 are provided with a sliding trolley 7, and the fixed plate 1 is provided with an open slot 11; the diameter of the open slot 11 is larger than the outer diameter of the bearing spindle 6, and the diameter of the open slot 11 is smaller than the diameter of the bearing outer ring; a mounting space for the jack main body 51 is provided between the detaching plate 4 and the bearing 2.

When the utility model is used, firstly, the open slot 11 of the fixing plate is arranged on the bearing main shaft 6 at the rear end of the bearing with a larger shaft shoulder. The bottom of the fixed plate 1 and the bottom of the dismounting plate 4 are placed on a sliding trolley 7. Then, the jack main body 51 is placed between both the disassembly plate 4 and the bearing 2, and the jack main body 5 is placed above the slide carriage. The fixed plate and the detachable plate are connected by a pull rod 3, and a fastening nut on the pull rod is screwed down, so that the jack main body 51 and the bearing 2 are fixed between the fixed plate 1 and the detachable plate 4.
