    • The tapered roller bearing with rotational speed detection unit has a tone wheel 30 which is externally fixed to an outward-facing cylindrical surface 28 formed on the outer peripheral surface of an inner ring 21 on the front face side, a casing 32 which is internally fixed to an inward-facing cylindrical surface 29 formed on the inner peripheral surface of an outer ring 23 on the back face side, a sensor 33 which is supported inside the casing 32 so as to be faced to the tone wheel 30, whereby there is no interference between the structural components during assembly of the tapered roller bearing, so that the assembly operation can be performed in a similar manner to that for a standard tapered roller bearing not having a rotational speed detection unit, and that miniaturization and lightening of the bearing as well as simplification of the assembly operation are possible.
    • 具有转速检测单元的圆锥滚子轴承具有一个外轮固定在形成在前表面侧的内圈21的外周面上的向外圆柱面28上的色轮30, 到形成在背面侧的外圈23的内周面上的向内的圆筒形表面29,传感器33被支撑在壳体32的内部以面对色轮30,从而没有 在组装圆锥滚子轴承期间的结构部件之间的干涉,使得组装操作可以以与不具有转速检测单元的标准圆锥滚子轴承相似的方式执行,并且轴承的小型化和轻量化 并且可以简化装配操作。
