The ‘pie’ shaped top jaws provide a full wrap clamping around the work piece. This project also includes a custom spring loaded locating pin assembly. Designed to orient the customer’s workpiece allowing fast and accurate change over.

Pitch-line Gear Chucks

Introducing the series of pneumatic actuated pitch-line gear chucks.

 

Helical Gear Chuck

Spur Gear Chuck
Spur Gear Chuck

How can we help you?

These two chucks are 7-inch diaphragm chucks. For multiple gear sizes, chucks can be provided with interchangeable cages and top jaws.

How do we do it?

We attach a custom designed axial locator cage to a standard chuck. This contains a series of floating gage pins in a flexible mounting. Then, we load the gear over the pins into the chuck. The jaws clamp over the pins to center and grip the gear providing a “best fit” centerline of the pitch diameter.

 

Pitch line gear chucks can be provided in sizes from 3-inch to 12-inch diameter, sliding jaw or diaphragm models and can be applied to spur or helical gear applications.

Custom Diaphragm Chuck for milling precision gears

Every week exciting new projects are heading out the door, such as this Custom Diaphragm Chuck for milling precision gears.

Brief: The customers work piece is a small precision gear that requires milling on one face, timed to existing geometry.

Challenge: The outer diameter of this gear could not be touched so it needed to be gripped on the root diameter.

Solution: A Northfield DPH-400 (.00050” T.I.R.) 4” diameter diaphragm chuck was provided, with sub jaws, changeable inserts and stops for different sized work pieces.

  • The inserts are wire cut to clear the major diameter and clamp on the root diameter.
  • Changeable stop pads have timing pins, to orient the work pieces prior to clamping.
  • The base stop has a ground indicating band for initial setup.
  • The chucks ‘pull-back clamping’ action ensures the part is seated flat.
