Today talk about the disassembly method of needle roller bearings.
The percussive force is generally applied to the inner ring of the bearing. The percussive force of the shielded machine room should not be applied to the rolling elements and cage of the bearing. This method is simple and easy, but it can easily damage the bearing. When the bearing is at the end of the shaft, use less than the bearing The inner diameter of the copper rod or other soft metal material is pressed against the shaft end, and the bearing block is added under the bearing, and it can be removed by gently tapping with a hammer. In applying this method, attention should be paid to the proper placement of the cushion block and the correct focus point.
is used to remove tightly fitted bearings. First, pour the engine oil heated to about 100°C on the bearing to be dismantled with an oil pot. After the bearing ring is heated and expand, the bearing can be pulled out with a puller.
Using a press to push the bearing, work smoothly and reliably, without damaging the machine and the bearing shielding room. The press has manual push, mechanical or hydraulic press. Matters needing attention: The pressing point of the press should be at the center of the shaft, and it should not be biased.
Using a special puller, when disassembling, as long as the handle is rotated, the bearing will be slowly pulled out. When removing the outer ring of the bearing, the corners of the two legs of the puller should be opened outward; when removing the inner ring of the bearing, the two legs of the puller should be inward and stuck on the end face of the inner ring of the bearing.
