Problems solved by technology

[0005] Since this patent is a means of dismantling the gearbox and performing repairs on the machine tool, laser cladding, etc., but the large gearbox cannot be disassembled or there is no time to disassemble it on site, so this method is only applicable to small and medium-sized gearboxes. , or a large reducer with spare parts
In addition, the laser cladding method also has defects such as high repair cost and long repair time.
[0006] Therefore, due to the wear of the bearing hole of the large-scale reduction box, it has not been able to achieve better on-line repair, and it is urgent to study and solve it.

Abstract

The invention discloses a device for online repairing of large reduction gearbox bearing hole abrasion and a method thereof. The device comprises a portable boring machine, a positioning device and a middle supporting device. By means of positioning of the positioning device, the middle supporting device and a reduction gearbox, the portable boring machine sequentially bores bearing holes in the two sides of the reduction gearbox, so that online repairing of the bearing holes is achieved, and size precision, geometric tolerance and roughness of the repaired bearing holes can fully meet the requirements of a drawing. Besides, the bearing holes in the two sides are bored through one cutter, coaxiality precision is high, and the device is convenient to use.

Description

technical field [0001] The invention relates to the maintenance technology of the reduction box, and more specifically relates to an online repair device and method for the wear of the bearing hole of the large-scale reduction box. Background technique [0002] Due to the operation and use of metallurgical machinery and equipment for many years, the pin hole of the mechanical structural parts or the bearing hole of the gearbox box often suffers from wear and damage, and out-of-round phenomena occur. problems faced. [0003] Due to various reasons, the bearing hole of the reducer often has the phenomenon of running circles. Once the phenomenon of running circles occurs, it will cause the bearing hole of the reducer box to wear out, resulting in out-of-concentricity and out-of-round phenomena, resulting in excessive vibration when the equipment is running. Doesn't run smoothly. At the same time, it will also cause damage to the bearings and gears in the gearbox, so it must b...
