composite bearing Composite roller bearings are made of axial and radial two roller bearings assembled to reduce the bearing volume, simplify the installation structure, thereby reducing manufacturing costs. Composite roller bearing radial and axial bearing capacity are relatively large, the parts can be replaced, and more and more applications in a variety of mast lift system
Composite roller bearing-combined bearing, also known as the combination of roller bearings, the first is designed by the Europeans.
Composite roller bearings mainly by the following components:
1) Shaft head
Composite roller bearing installation is welding, the specific way is to shaft head and a round hole with the plate welding, and then and mast assembly;
2) main roller
The main roller is the main bearing in the composite roller bearing, mainly bear the vertical direction of the load, requires a strong wear resistance of the corrosion resistance and impact resistance. While the main roller can also be used for single-way bearing alone, because it is a full complement of the roller structure of the roller bearings;
3) side roller
Side roller is a composite bearing in the composite bearing, mainly to bear the horizontal direction of the load, also requires a strong wear resistance of the corrosion resistance and impact resistance. The side roller is essentially a roller bearing with no inner ring filled with needle roller, and the inner part of the compound roller bearing is fitted with the mandrel and the shaft head.
4) cover plate
So that the main side of the roller shaft head together to become a whole;
Composite roller bearing assembly:
composite bearing The side roller is mounted on the shaft head through the mandrel, the main roller sets outside the shaft head, the cover is fixed by the nut at the end of the shaft head, and finally the parts are fixed together.
Reduce design and production costs. Acceptable high radial and axial loads. Rugged rails for high dynamic and static loads. The bearing capacity is well distributed on the rails. Bearings and rails have a long service life. Can be assembled by welding bolts, economical and practical. The bearing parts are easy to replace.
