Abstract
A fixed, non-rotating shaft supports a resilient roller for rotation and oscillation by means of bearing assemblies adjacent opposite ends of the roller. Each bearing assembly comprises a rotary bearing mounted inside the respective end of the roller and a reciprocating bearing assembly mounted in a respective keyway on the shaft so that the roller rotates about the fixed shaft but oscillates and reciprocates for a limited distance in opposite directions. The rotary bearing has the reciprocating bearing mounted therein in a housing as a subassembly.
Claims5
In a roller assembly:
- a roller,
- a shaft mounted in and through said roller and being fixed against rotation, and bearing means supporting said roller for rotation and reciprocation on said shaft,
