The characteristics of cross roller bearings

FileCross-roller bearings may not be familiar to the readers here. In fact, it is a kind of bearing used to divide the inner For bearings that rotate with inner and outer rings, the manufacturer will install rollers and spacers on the divided inner and outer rings to fix the cross roller rings together. Avoid separation, and the overall installation process is quite simple. Since the rollers in the cross roller bearing are arranged in a cross pattern, only one cross roller is needed to withstand loads from all directions. Compared with some traditional models on the market, its rigidity is increased several times. At the same time, because its inner ring and outer ring are separated by a structure, the gap in the cross roller bearing can be adjusted. It adds some loads and can also perform rotational motion with high precision. At the same time, due to its special structure, many manufacturers of industrial robots use this type of crossed roller bearing as a spherical bearing.

Its internal structure adopts The rollers are arranged in a perpendicular and cross-shaped manner, and are also equipped with retainers and isolation blocks to prevent the rollers inside from causing friction between different rollers during the tilting process. There will be no contact or even locking between them, so the rotation accuracy is quite high. And because the inner and outer rings are separated from each other, the structural gap can be adjusted, and the operation is simple during installation. .

　

　　The sizes of the inner and outer rings of the crossed roller bearing have been made very small by the manufacturer. Especially for some thin and small structures, it is more suitable for some precision parts, such as the rotating part of the robot, medical equipment, precision rotating worktable, etc., and has a wide range of uses. The existence of cross roller bearings reduces the processing The cost and length of the shaft, and the range of geometric changes caused by its thermal expansion is quite small. Although the structure of the crossed roller bearing is quite simple, the lubrication is very sufficient.
