Problems solved by technology

However, in the maintenance process, this type of puller is difficult to disassemble for some parts installed in the hole, such as: some end covers, bearings and other parts installed in the hole
Especially for some heavy machinery (such as: straightening machine, assembly machine), this type of machine needs to use rollers to roll steel plates, so the rollers and end covers are easy to deform, and when the rollers fail, the end covers are difficult to disassemble. And the bearings inside are also difficult to disassemble and replace.

Description

technical field [0001] The invention relates to a maintenance tool for mechanical equipment, in particular to a wheel puller for hole sleeve parts. Background technique [0002] In industrial production, various failures will inevitably occur during the operation of machinery and equipment, which requires specialized maintenance masters to repair, but many machine parts are severely corroded, and some parts are installed with interference, making it difficult to disassemble. Therefore, how to quickly disassemble the equipment and efficiently maintain the equipment is directly related to the interests of the enterprise's production. [0003] At present, there are many kinds of pullers for external use on the market, and the main objects of this kind of pullers are parts installed on the shaft, such as gears, pulleys, sprockets, etc. However, in the maintenance process, this type of puller is difficult to disassemble for some parts installed in the hole, such as: some end cov...
