Abstract
A sprocket segment assembly for use with a sprocket of a tracked machine includes a first circumferential sprocket segment including a tooth with a first bushing contact surface, a second bushing contact surface, and a top surface extending circumferentially between the first bushing contact surface and the second bushing contact surface. The first bushing contact surface defines a cavity, and a roller extending proudly of the first bushing contact surface.
Claims19
A sprocket for use with a track assembly, the sprocket defining a radial direction, a circumferential direction, and an axial direction, the sprocket comprising:
- at least a first circumferential sprocket segment including at least one tooth with a first bushing contact surface, a second bushing contact surface, and a top surface extending circumferentially between the first bushing contact surface and the second bushing contact surface,
- wherein the first bushing contact surface defines:
- a first cavity extending radially from the top surface, and
- a second cavity extending from the first bushing contact surface to the first cavity, and
- wherein the first cavity is spaced away from an intersection of the first bushing contact surface, and the top surface, forming a front side edge;
- and
- a roller that is disposed in the second cavity.
A sprocket segment assembly for use with a tracked machine, the sprocket segment assembly defining a radial direction, a circumferential direction, and an axial direction, and the sprocket segment assembly comprising:
- at least a first circumferential sprocket segment including at least one tooth with a first bushing contact surface, a second bushing contact surface, and a top surface extending circumferentially between the first bushing contact surface and the second bushing contact surface;
- and
- a roller that is extending past the first bushing contact surface.
A spring loaded roller subassembly for use with a sprocket, the spring loaded roller subassembly comprising:
- a roller configured to be disposed in a cavity of a tooth of the sprocket;
- a yoke;
- and
- a compression spring
- wherein the yoke includes two arms,
- wherein the roller includes a cylindrical body including two end faces that are rotatably attached to the two arms, and
- wherein the roller defines a diameter that is less than a center cavity radial dimension defined by the cavity.
