A World brand 40-ton gear punch has failed: the machine vibrates very strongly. After a detailed inspection, it was found that the shaft hole of the pulley and the rotating shaft were worn too seriously, causing the two to be misaligned, causing the entire machine to vibrate severely. Generally speaking, to deal with this kind of failure, it is necessary to disassemble the pulley and rotating shaft, then send it out for processing, and then install it back.

After the author checked the fault, I was determined not to let it go, and wanted to find another way to solve this problem. Let’s take a look together~
01
dismantling work
The disassembly work began, and the pulley was easily removed. When it was time to remove the rotating shaft, the author was confused: is it to the right? Or to the left? No matter which way it is removed, the pinion fixed on the rotating shaft must be removed first. However, the pinion cannot be removed, and the puller cannot be used (the space is too small to fit the puller hook). Every conceivable method has been used, and the pinion cannot be removed. It is simply a roadblock in the road of maintenance work, making me both embarrassed and exhausted… I really wanted to give up and apply for external repairs from the manager, but on second thought, I also applied for external assistance when removing the rotating shaft.

Another way
The author carefully observed it again, and my brain was quickly searching for feasible solutions. Suddenly got inspiration: since the pinion is so difficult to disassemble, just don’t move it, don’t mess with it, just go around and go. My goal is to turn the shaft, not the pinion. Since the two cannot be disassembled separately, then treat them as an accessory and disassemble them together (after processing it out, put them back together).
This solution has a disadvantage: the large gear must be removed first (the large gear blocks the bearing base of the rotating shaft, thus blocking the disassembly direction of the pinion and the rotating shaft). The disassembly and installation of the large gears account for a large proportion of the entire maintenance workload. In view of its own level and rudimentary maintenance tools, it can be said that this solution is the dumbest, but also the most effective. Manufacturer of metal equipment in Xiamen, China
Acting according to the plan, although the workload is heavy and the detours are taken, the effect is very obvious: after the large gear is removed, the pinion, the rotating shaft and the bearing seat are quickly removed as an accessory at one time. , is simply uprooted.
The most stupid way has become the best way. It seems like a detour, but it is actually a shortcut! Manufacturer of metal equipment in Xiamen, China
