The invention discloses a bearing drawing device. The bearing drawing device comprises a base, and a lead screw penetrating through the base; one part, extending out of the top of the base, of the lead screw is in threaded connection with a turntable; one part, extending out of the bottom of the base, of the lead screw is detachably connected with a drawing nut; and the outer diameter of the drawing nut is larger than the inner diameter of a bearing to be drawn and smaller than the outer diameter of the bearing to be drawn. Most structures of the device are positioned on one side of the bearing to be drawn; the drawing nut is positioned on the other side of the bearing, and is butted against the side surface; then, the drawing nut is connected with the part, extending out of the bottom of the base, of the lead screw; the turntable rotates to hoist the lead screw to a position opposite to the base; and the base can use an external box body as a strength point for hoisting the drawing nut along with the lead screw and taking out the bearing. Through the structural design, the bearing drawing device is simple in structure, convenient for use and flexible adjustment and less in storage space.
Description
technical field [0001] The invention relates to the technical field of mechanical equipment maintenance, and more specifically relates to a bearing lifting device. Background technique [0002] Bearings are an important part of contemporary mechanical equipment, mainly used to support the mechanical rotating body, reduce the friction coefficient during its movement, and ensure its rotation accuracy. Bearings can be divided into two categories: rolling bearings and sliding bearings, among which rolling bearings are more commonly used. [0003] Rolling bearings are generally composed of four parts: outer ring, inner ring, rolling elements and cage. Faults or failures may occur during use, so the bearings need to be pulled out for easy inspection and maintenance. [0004] At present, the commonly used method is to hit the pin shaft of the bearing with a hand hammer until the bearing is shot down from the bearing installation. The damage to the inner ring of the bearing and t...
