Apparatus for measuring rotational velocity of a shaft
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.
