NONCONTINUOUS ABRASIVE WHEEL Russian patent published in 2000 - IPC

FIELD: mechanical engineering, namely, grinding and polishing wheels. SUBSTANCE: noncontinuous abrasive wheel may be used at machine-building plants. It has moving flange, holder with flange and cups with abrasive members positioned in holder. Moving flange is driven for rotation with respect to holder. Flange drive includes rod, pin passing through helical recess of rod and return spring. Two ratchet wheels are mounted on rod and moving flange for engagement. Cups are spring-loaded relative to holder flange and installed in contact with moving flange. The latter has slanting end face on side of contact. End-face slope angle depends on average distance between abrasive grains of abrasive members and space between cups. EFFECT: higher stability of tool. 3 cl, 3 dwg
