Description

Technical Field

[0001] The utility model relates to the technical field of bearing maintenance, in particular to a device for disassembling bearings. Background Art

[0002] In the prior art, during the ironmaking production process in a steel plant, when the bearing of an equipment component reaches the end of its service life or the inner ring, outer ring, rolling element and retainer of the bearing are damaged to varying degrees, the bearing will be unable to continue to operate and use, and the equipment needs to be shut down to replace the bearing. When replacing and disassembling the damaged bearing, maintenance personnel often remove the outer ring and retainer of the bearing by gas welding, and then use gas welding to bake the inner ring and remove the inner ring by hammering with a hand. When the inner ring is difficult to remove, it needs to be removed by gas welding. During the cutting process, the shaft is often damaged. If the shaft damage is not handled in time, the new bearing cannot be installed. When handling the shaft damage, the maintenance personnel waste more time and increase the workload, and even affect the normal production order. Utility Model Content

[0003] The purpose of the utility model is to provide a device for disassembling bearings to solve the above-mentioned shortcomings. The damaged bearings can be quickly disassembled, thus avoiding the waste of man-hours of maintenance personnel, reducing the labor intensity of maintenance personnel, and ensuring stable production order.

[0004] The technical solution of the utility model is: a device for disassembling bearings, characterized in that it includes a front movable clamping plate and a rear fixed plate, an adjusting screw is connected at intervals between the front movable clamping plate and the rear fixed plate, a tightening screw is connected in the middle of the rear fixed plate, the tightening screw is provided with a ring, and the corresponding adjusting screws on both sides are also provided with rings and are horizontally connected to the rings on the tightening screw; one side of the front movable clamping plate is provided with a notch that is engaged with the bearing shaft where the unloaded bearing is located.

[0005] The holes on the front movable clamping plate and the rear fixed plate connected with the adjusting lead screw are long strip holes.

[0006] The advantages of the utility model are: the device has a reasonable structure, is simple to manufacture, is easy to use, can quickly disassemble the bearing, improves the working time utilization of maintenance personnel, and reduces labor intensity, providing support for smooth production.

[0007] The embodiments of the present invention will be described in further detail below in conjunction with the accompanying drawings. BRIEF DESCRIPTION OF THE DRAWINGS
