UNITIZED TONE RING ASSEMBLY

摘要

A tone ring assembly for use on a rotatable machine part. The tone ring (10) is able to generate a varying voltage output when rotated at varying speeds. A fixed position magnetic sensor detects this voltage. The tone ring comprises an axially extending main body portion (18) having a plurality of areas able to generate a voltage upon rotation (32, 34). A retainer (75) having at leas t one radial flange prevents axial movement of the tone ring and the tone ring includes ribs and spaces on its inside diameter to permit oil to pass therethrough.
