  • Roller assembly with roller retention mechanism
    Patent number: 4398777
    Abstract: The roller retention mechanism includes at least three portions each extending into contact with two adjoining rollers. The rollers are wedged apart circumferentially. The "keystoning" effect presses all the rollers against the wall of the bore in the roller assembly with sufficient force to prevent axial movement of the rollers and to radially retain the rollers in the roller assembly. The roller retention mechanism is constructed and arranged to be subsequently pushed axially from the roller assembly.

  • Roller assembly with roller retention spring
    Patent number: 4166660
    Abstract: A folded spring extends relatively diametrically across the circle of rollers in a roller assembly with each diametral side pressing between two adjoining rollers to wedge these rollers apart circumferentially and thus to press all the rollers against the wall of the bore in a "keystoning" effect with sufficient force to prevent axial movement of the rollers and to radially retain the rollers in the body. The spring is arranged to be subsequently pushed axially from the body.
