Abstract
The support assembly contains a shaft in the form of a shallow pipe. At the ends of the shaft, separated from each other, roller bearings are installed. Their inner rings are mounted on the shaft, and the outer rings are installed in the body. Roller bodies are placed between the rings. If a cogged cage is used, they are separated by the cage teeth. The tubular support of the cage slides along the rigidly fastened cylindrical rod. Oil is supplied under pressure to the passage of the cylindrical rod. The roller bearings receive loads transferred to them from the shaft, and the support sliding over the rod form together a friction bearing which compensates for the harmful impacts of the centrifugal forces on the cage.
Claims8
A support assembly, comprising:
- a body and a shaft in the form of a pipe disposed in the body;
- a cylindrical rod coupled to the body and having oil supply passages;
- and
- at least two roller bearings including cages mounted on the shaft, the cages having a cage support in the form of a pipe disposed inside the shaft coaxially with the shaft and with the cylindrical rod.
A bearing assembly, comprising:
- a body having two spaced apart sections;
- a cylindrical hollow shaft disposed between the sections;
- bearings having cages and selectively coupling the shaft to the sections;
- a cylindrical hollow cage support coaxially disposed in the shaft;
- and
- a cylindrical rod rigidly fastened to the body and moveably and coaxially disposed in an opening of the cage support.
