    • An apparatus is disclosed for mounting a rotational signal transducer on a rotary shaft where the transducer generates a signal proportional to the shaft's rotational velocity. The apparatus includes a gear mounted for rotation with the shaft. A support platform is rotatably secured to the shaft by a roller bearing. The roller bearing permits the shaft and platform to rotate relative to one another but prevents relative axial motion between the shaft and platform. A transducer is mounted on the platform and operably aligned over the gear and generates a signal as gear teeth pass the transducer. A torque rod pivotally fixed to both the platform and a stationary support restrains the platform from rotating with the shaft. The pivotal connections of the torque rod permit the platform to move axially with the shaft.
    • 公开了一种用于将旋转信号传感器安装在旋转轴上的装置,其中换能器产生与轴的旋转速度成比例的信号。 该装置包括安装成与轴一起旋转的齿轮。 支撑平台通过滚子轴承可转动地固定在轴上。 滚子轴承允许轴和平台相对于彼此旋转,但是防止轴和平台之间的相对轴向运动。 传感器安装在平台上并可操作地对准齿轮并在齿轮通过换能器时产生信号。 枢转地固定到平台和固定支撑件上的扭矩杆限制平台与轴一起旋转。 扭矩杆的枢转连接允许平台与轴向轴向移动。
