  • Patent number: 5341603
    Abstract: A honing fixture includes a mounting ring 30 carrying a plurality of circumferentially spaced rollers 32. A ring gear 34 rotates about rollers 32 and carries segmented ring segments 40a and 40b for rotation therewith about a honing axis. Ring segments 40a and 40b carry honing stones, the segments being pivotally coupled to one another at one end and biased for closing movement toward one another at the opposite end. A suspension structure supports the honing fixture 14 from a support assembly 12 in a manner to compensate for applied torque loading on the honing fixture and its weight. The suspension structure includes a pair of pivoted arms 72 and 74 carrying the weight of the honing fixture at their distal ends and engaging at their proximal ends a spring 90. The honing fixture 14 is mounted for translation movement along guides 18.
