Abstract: A tracked undercarriage roller assembly including a roller body having a through cavity delimited by a radially inner surface, a shaft in the through cavity, a bushing extending from a first axial end to a second axial end and radially interposed between the roller body and the shaft, an annular chamber at least partially filled with a lubricant and radially interposed between the shaft and the bushing, a housing seat in the shaft including an inlet portion facing an axial end surface of the shaft and a measuring portion inside the shaft in an axial position between the first and second axial ends of the bushing, wherein the inlet portion and the measuring portion are aligned along an axial direction. A temperature transducer is inside the housing seat at the measuring portion, wherein the measuring portion is at a radial distance from the bushing between 8 millimetres and 50 millimetres.

Abstract: A track pin assembly includes a pin having a first axial end and a second axial end configured to engage a respective outer link of a joint, a first cavity which defines a tank for containing lubricating oil or grease, and a second cavity arranged at the second axial end of the pin and open at the second axial end of the pin. A sensor, arranged in the second cavity, includes a sensor element configured to measure a temperature and to generate a signal indicative of the measured temperature, and a transmitter configured to irradiate a measuring signal that is representative of the signal generated by the sensor element. A power source, arranged in the second cavity, is configured to constantly supply the sensor.

Abstract: An anti-galling method for treating materials, which provides for subjecting at least one of the at least two components mutually coupled with at least one degree of freedom, made of metallic material, to a first preliminary step of thermal treatments to increase surface hardness and to a second preliminary step of surface grinding. The method further includes the steps of: washing at least one portion of the surface of the at least one component subjected previously to the preliminary steps; shot peening the at least one portion of the surface of the at least one component previously subjected to washing; and applying a layer of molybdenum disulfide to the at least one portion of the at least one component previously subjected to shot peening.
