Wear monitoring device and method of monitoring undercarriage and roller wear
First Claim
1. An undercarriage monitoring device, comprising:
- a roller assembly of a track-type undercarriage including,a roller housing mounted to a frame of the track-type undercarriage, anda roller including a ferrous material and an end of the roller extending into the roller housing, the roller configured to rotate with respect to the roller housing;
a bushing comprising a non-ferrous material and press fit into the roller housing;
a Hall effect sensor disposed in an opening of the roller housing, wherein the non-ferrous material of the bushing contacts the Hall effect sensor and extends uninterrupted as a uniform body of material from the Hall effect sensor to the roller; and
a magnet disposed in the opening of the roller housing over the Hall effect sensor.

Abstract
An undercarriage monitoring device has a roller assembly including a fixed roller component and a bushing. An opening is formed within the fixed roller component. A first sensor is disposed within the opening of the fixed roller component over the bushing. The first sensor is configured to sense a first physical characteristic of the bushing. The fixed roller component is a shaft or a housing. The first sensor is a temperature sensor or a Hall effect sensor. A magnet is disposed on the roller assembly. A second sensor is disposed within the opening of the fixed roller component over the bushing. The second sensor is configured to sense a second physical characteristic of the bushing. A data transmitting device is coupled to the first sensor. Data is collected from the sensor. The data collected from the sensor is transmitted to a receiving device.

13. A method of monitoring an undercarriage, comprising:
-
providing a roller assembly of an undercarriage including, a fixed roller component, and a rotating roller component comprising a ferrous material; disposing a bushing comprising a non-ferrous material between the fixed roller component and the rotating roller component, wherein the non-ferrous material of the bushing extends continuously from the fixed roller component to the rotating roller component; disposing a Hall effect sensor on the fixed roller component adjacent to the bushing; and determining wear on the bushing by measuring a thickness of the bushing using the Hall effect sensor. - View Dependent Claims (14, 15, 16, 17, 18)

19. An undercarriage comprising:
-
a roller housing; a bushing including a non-ferrous material press fit into the roller housing; a Hall effect sensor disposed in the roller housing, the Hall effect sensor configured to detect a wear of the bushing based on a thickness of the bushing; a roller including a ferrous material and an end of the roller extending into the roller housing, wherein the non-ferrous material of the bushing extends continuously from the roller housing to the roller; and a data processor disposed in communication with the Hall effect sensor, wherein the data processor is located remote to the Hall effect sensor and is configured to provide an alert based on the wear of the bushing. - View Dependent Claims (20, 21, 22, 23, 24, 25)
