A crawler-type undercarriage roller assembly (17) comprising: a roller body (18) having a through cavity (19) delimited by a radially inner surface (20); a shaft (22) which is inserted into the through cavity (19) of the roller body (18); a bushing (32) extending from the first axial end (32a) to the second axial end (32b) and interposed radially between the roller body (18) and the shaft (22); an annular chamber (34) at least partially filled with a lubricant and radially interposed between the shaft (22) and the bushing (32); a housing seat (37) obtained in the shaft (22) and comprising an inlet portion (39) facing an axial end surface (22d) of the shaft (22) and a measuring portion (40) placed within the shaft (22) in an axial position between a first axial end (32a) and a second axial end (32b) of the bushing (32), in which the inlet portion (39) and the measuring portion (40) are aligned with each other in the axial direction. The temperature transducer (41) is placed inside the receiving seat (37) at the measuring portion (40), where the measuring portion (40) is placed at a radial distance of 8 mm to 50 mm from the bushing (32).
一种履带式底架辊子组件(17),包括:辊子本体(18),该辊子本体(18)具有由径向内表面(20)界定的通腔(19);轴(22),该轴(22)插入到辊子本体(18)的通腔(19)中;衬套(32),该衬套(32)从第一轴向端部(32a)延伸至第二轴向端部(32b)并且径向地插置在辊子本体(18)与轴(22)之间;环形腔室(34),该环形腔室(34)至少部分地填充有润滑剂并且径向地插置在轴(22)与衬套(32)之间;容纳座(37),该容纳座(37)在轴(22)中获得并且包括入口部分(39)和测量部分(40),该入口部分(39)面向轴(22)的轴向端表面(22d),该测量部分(40)被放置在衬套(32)的第一轴向端部(32a)与第二轴向端部(32b)之间的轴向位置中的轴(22)内,其中,入口部分(39)和测量部分(40)沿着轴向方向彼此对准。温度换能器(41)放置在容纳座(37)内部、在测量部分(40)处,其中,测量部分(40)放置在距衬套(32)在8毫米至50毫米的径向距离处。
