Turn pink worm to move three blue jaws radially via green sliders and grey block (gear and grooved disk) for clamping or releasing workpieces (not shown).
The self-locking feature of the worm drive helps clamp the worpieces steadily.
In comparison with the traditional chuck of spiral disk:
Advantages:
- easy manufacture.
- quick action
Disadvantages:
- for a defined input torque the clamping forces are not the same for workpiece different diameters.
- limited turning positions because only one pink worm can be arranged.
