Abstract
A lash adjustment system for a roller is provided which includes a cam plate surface and a frustoconically shaped roller in mechanical communication with the surface. Means for moving the roller relative to the surface are included to urge the roller inwardly with respect to the cam plate in order to reduce lash.
Claims28
A lash adjustment system for a roller, comprising:
- a cam plate having a first surface;
- a roller in mechanical communication with the first surface, the roller having a frustoconical shape;
- and
- means for moving the roller relative to the surface.
1 more element
A lash adjustment system for a roller, comprising:
- a cam plate having a track portion for a roller, the track portion having a first surface, a second surface, a thickness between the first and second surface, an inner side, an outer side, and a width between the inner side and the outer side;
- a first roller in mechanical communication with the first surface of a cam plate track portion to allow rotational engagement of a roller surface with the first surface of the cam plate track portion, the first roller having a rotational axis and a frustoconical shape defining a base portion of the first roller having a larger cross-sectional diameter compared to a top portion of the first roller;
- and
- force applying means for moving the first roller towards the inner side of the cam plate.
1 more element
A method for reduction of lash between a roller and a surface, comprising:
- providing a system comprising a cam plate having a track portion for a roller, the track portion having a first surface, a second surface, a thickness between the first and second surface, an inner side, an outer side, and a width between the inner side and the outer side;
- a first roller in mechanical communication with the first surface of a cam plate track portion to allow rotational engagement of a roller surface with the first surface of the cam plate track portion, the first roller having a rotational axis and a frustoconical shape;
- and
- force applying means for moving the first roller towards the inner side of the cam plate, wherein lash is present between the first roller and the first surface of the cam plate;
- and
- applying force to a first roller, moving the first roller towards the inner side of the cam plate, such that lash between the first roller and the first surface of the cam plate is reduced.
3 more elements
A lash adjustment system for a roller, comprising:
- a cam plate having a track portion for a roller, the track portion having a first surface, a second surface, a thickness between the first and second surface, an inner side, an outer side, a width between the inner side and the outer side, wherein the inner side and outer side are substantially parallel;
- a first roller in mechanical communication with the first surface of a cam plate track portion to allow rotational engagement of a roller surface with the first surface of the cam plate track portion, the first roller having a rotational axis and a frustoconical shape defining a base portion of the first roller having a larger cross-sectional diameter compared to a top portion of the first roller, wherein the rotational axis of the first roller is not perpendicular to the inner and outer sides.
