Abstract
A wear detection device is disclosed herein. The wear detection device may comprise: a housing including a transparent tube, the housing configured to receive a photoconductive fluid; a first casing disposed at a first end of the housing; and a power source disposed in the first casing, the power source configured to power a transmitter in response to the transparent tube being exposed to light. An electrical circuit may be closed in response to an entire length of the transparent tube being exposed to light or only a portion of the transparent tube being exposed to the light.
Claims20
A wear detection device, comprising:
- a housing including a tube, the housing configured to receive a photoconductive fluid;
- a first casing disposed at a first end of the housing;
- and
- a power source disposed in the first casing, the power source configured to power a transmitter in response to the tube being exposed to light.
A brake roller assembly, comprising:
- an axle assembly;
- a brake roller disposed radially outward from the axle assembly, the brake roller configured to rotate about a brake roller axis;
- a friction sleeve coupled to the brake roller;
- and
- a wear detection device disposed radially inward from a radially outer surface of the friction sleeve, the wear detection device configured to transmit a signal in response to an electrical circuit being closed due to the friction sleeve wearing to at least one of a predetermined wear depth and a predetermined wear length.
A wear detection system for a brake roller assembly, comprising:
- a wear detection device configured to be disposed radially inward from an outer surface of a friction sleeve of the brake roller assembly, the wear detection device including a power source and a transmitter;
- a receiver in electronic communication with the transmitter;
- and
- a controller in electronic communication with the receiver, the controller configured to receive, from the receiver and through a transmitted signal by the transmitter, an indication that the friction sleeve has worn locally to a depth of the wear detection device.
