Cross Roller Bearing

Percussion method: The percussion force is generally applied to the inner ring of the cross roller bearing, and the percussion force of the shielding machine room should not be added to the rolling element and cage of the cross roller bearing. This method is simple and easy to implement, but it is easy to damage the cross For roller bearings, when the crossed roller bearing is at the end of the shaft, use a copper rod or other soft metal material smaller than the inner diameter of the crossed roller bearing against the shaft end, add a spacer under the crossed roller bearing, and tap it lightly with a hammer Click to remove it. When applying this method, attention should be paid to the proper placement of the pad and the correct focus point.

Pull-out method: Use a special puller. When disassembling, as long as the handle is rotated, the cross roller bearing will be slowly pulled out. When disassembling the outer ring of the cross-roller bearing, the corners of the two legs of the puller should be opened outward; when removing the inner ring of the cross-roller bearing, the two legs of the puller should be inward and stuck on the end face of the inner ring of the cross-roller bearing.

Pushing method: Use a press to push the crossed roller bearing to work smoothly and reliably, without damaging the machine and the shielded machine room of the crossed roller bearing. The press has manual push, mechanical or hydraulic pressure. Note: The pressing point of the press should be at the center of the shaft, and it should not be biased.

Hot dismantling method: Used to dismantle tightly fitted cross roller bearings. First, pour the engine oil heated to about 100°C on the cross roller bearing to be dismantled with an oil can. After the cross roller bearing ring is heated and expand, the cross roller bearing can be pulled out with a puller.
