摘要： A novel stationary comprises top jaws 21 each carried by base jaw 7 which in turn is carried on a chuck body 2 which sits on the chuck base 3. In the base 3 is a gearing system comprising a pinion 13 which meshes with a cam gear 6. The cam gear 6 carries slots that accept load pins 4 which are fixed to and carried by the base jaws 7. The load pins 4 mate with recesses in the under surface of the top jaws 21. The pinion 13 has a recess in its upper surface for receiving a turn key to turn the pinion and activate the gearing system. To close the chuck, a turn key is inserted into the pinion 13 and the pinion is rotated. Meshing cam gear 6 is caused to rotate simultaneously. As the cam gear rotates, the load pin travels in the slot 31 between the radially outermost portion of the slot and the radially innermost portion of the slot. The load pin 4 which is constrained from moving in an arcuate motion is forced to travel radially inward of the front plate 1 of the chuck carrying with it the top jaw 21. The chuck provides a compact, efficient and effective alternative to conventional scroll operated chucks.
