IDEA NOTE Chuck mechanism utilizing gears
By using gears with different numbers of teeth to rotate the chuck, different opening and closing angles between the arms are achieved.
IDEA NOTE Flanged bearings are utilized on the work hand rotary shafts.
By fitting flanged bearings in the through holes without machining the bearing housing with steps, rotary bearing mechanisms that press the shafts from both sides are achieved. To prevent excessive push by the shaft collars, spacers are added on the central inner ring side.
IDEA NOTE Secure oil free bushings
Secure the oil free bushings with truss screws to reduce cost.
