A crawler-type chassis roller assembly (17) comprising: a roller body (18) having an inner cavity (19) defined by a radially inner surface (20); the shaft (22) is inserted into the inner cavity (19) of the roller body (18); a rolling bearing (36) comprising a single radially outer bearing ring (39), a first radially inner bearing ring (42), a second radially inner bearing ring (43), a first rolling body assembly (40) radially interposed between the radially outer bearing ring (39) and the first radially inner bearing ring (42), and a second rolling body assembly (41) radially interposed between the first rolling body assembly (40) and the second rolling body assembly (41). The second rolling body assembly (41) is radially interposed between the radially outer bearing ring (39) and the second radially inner bearing ring (43), where the radially outer bearing ring (39) is in contact with the radially inner surface (20) of the roller body (18), and where the first radially inner bearing ring (42) and the second radially inner bearing ring (43) are in contact with the shaft (22).

    一种履带式底盘滚轮组件(17),包括:滚轮本体(18),滚轮本体(18)具有由径向内表面(20)限定的内腔(19);轴(22),轴(22)插入到滚轮本体(18)的内腔(19)中;滚动轴承(36),滚动轴承(36)包括单个径向外轴承环(39)、第一径向内轴承环(42)、第二径向内轴承环(43)、第一滚动体组件(40)和第二滚动体组件(41),其中,第一滚动体组件(40)径向地介于径向外轴承环(39)与第一径向内轴承环(42)之间,第二滚动体组件(41)径向地介于径向外轴承环(39)与第二径向内轴承环(43)之间,其中,径向外轴承环(39)与滚轮本体(18)的径向内表面(20)接触,并且其中,第一径向内轴承环(42)和第二径向内轴承环(43)与轴(22)接触。
