A track pin may comprise a body that includes a generally cylindrical configuration defining an axis of rotation, a circumferential direction and a radial direction, the body defining a first end, a second end and a peripheral surface extending from the first end to the second end. The peripheral surface may include a first lobed portion spaced axially away from the first end and the second end and including a series of convex arcuate segments and concave arcuate segments joined to each other tangentially, forming an undulating surface.

A torque monitoring device for a fastener is provided. The torque monitoring device includes a sensing element mounted within the fastener. The sensing element measures a value of fastener elongation. The torque monitoring device also includes a receiving element coupled to a torque machine. The receiving element is communicably coupled with the sensing element. The receiving element is configured to receive the value of fastener elongation from the sensing element. The receiving element is also configured to generate an alert for terminating a torque operation being performed by the torque machine when the value of fastener elongation exceeds a pre-set value of fastener elongation.

Torque monitoring device

An apparatus to wirelessly monitor selected sensors of a machine having a plurality of sensors includes a touchscreen display configured to display a graphical user interface (GUI) and a processor or processing circuitry that receives and analyzes data wirelessly transmitted from the selected sensors. Selection of the sensors can include display on the GUI of a first user input to receive a selection to select the machine from a predetermined list of machines, a second user input to receive an input to identify and monitor one or more operating characteristics of the machine, and a third user input to receive one or more inputs to individually associate sensor identifiers with graphics corresponding to the candidate sensor selection locations to select the sensors from which to receive and analyze data to monitor the one or more operating characteristics of the machine.

Operator interface for wireless sensing and system and method thereof

A track bolt for an undercarriage system includes a head portion. The track bolt also includes a body portion extending from the head portion. The track bolt further includes a piezo ceramic sensor mounted in a counter bore provided in the track bolt. The piezo ceramic sensor measures a value of track bolt elongation such that the value of the track bolt elongation is used to calculate a clamping force in the track bolt. The track bolt includes a plug member disposed in the counter bore for sealing the piezo ceramic sensor.

The wheel attachment for stationary exercise bike is an attachment adapted for use with a stationary exercise bike. The wheel attachment for stationary exercise bike is adapted for use in cross-training. Specifically, the wheel attachment for stationary exercise bike is a rotating handle bar that is mounted on the stationary exercise bike. The wheel attachment for stationary exercise bike is mounted on a pivot that allows the wheel attachment for stationary exercise bike to be rotated in a first plane of rotation that is perpendicular to a second plane of rotation that is defined by the rotation of the pedals of the exercise bike. The wheel attachment for stationary exercise bike comprises a pivot, a handle bar, a strut, and a front tire apparatus.

A track link having a wear sensing device is disclosed. The track link may include a link body including a surface, a cavity, and at least one hole configured to receive a track pin. The track link may further include the wear sensing device positioned in the cavity. The wear sensing device may be configured to generate a signal indicative of a wear parameter of the surface. The track link may further include a containment mechanism configured to secure the wear sensing device in position inside the cavity.
