Abstract
A roller of an undercarriage track system for a machine is disclosed. The roller includes a body and a sensed feature. The body is a solid of revolution formed about a roller axis. The body includes a bore surface and a roller contact surface. The bore surface defines a bore extending through the body. The bore surface is a radially inner surface of the body. The roller contact surface is located outward from the bore surface. The sensed feature is located at the body. The sensed feature is configured to rotate with the body and to be detectable by a sensor.
Claims8
A track roller assembly of an undercarriage track system for a machine, the track roller assembly comprising:
- a roller including
- a body formed as a solid of revolution about a roller axis, the body including
- a bore surface defining a bore extending through the body, the bore surface being a radially inner surface of the body and being a cylindrical shape, and
- a roller contact surface located outward from the bore surface, the roller contact surface being a surface of revolution about the roller axis, and
- a sensed feature protruding from the body into the bore;
- a roller shaft including a shaft body extending through the bore;
- a bearing disposed between the roller and the shaft;
- and
- a sensor embedded in the shaft body, the sensor being axially aligned with the sensed feature and radially positioned to detect the sensed feature when the sensed feature rotates past the sensor.
