Gear production

Gear hobbing

Beispiel 1 Hydra-Clamping-Arbor

Actuation: Power actuatedaxially
Mounting: Flange; short taper
Workpiece: Gearwheel
Machine: CNC-Gear-hobbingmachine
Application: Gear Hobbing
Advantage: High precision centering of the gear;run-out accuracy<- 0,003 mm (0.00012");Thus quieter running in the assembled stage is achieved. Additionally the workpiece is being clamped axially by a holder.

Example 2 Hydra-Clamping-Arbor

Actuation: Power actuated axially
Mounting: Steep taper 40
Workpiece: Gearwheel
Machine: CNC-Gear-hobbingmachine
Application: Gear Hobbing
Advantage: High precise centering of the gear; run-out acccuracy <- 0,003 mm (0.00012"); Additionally the workpiece is being clamped by a holder; compen-sation of the run-out mistakes at the workpiece by a pendulum holder

Example 3 Hydra-Clamping-Arbor

Actuation: Power actuated axially
Mounting: Flange, short taper
Workpiece: Gearwheel
Machine: CNC-Gear-hobbingmachine
Application: Gear Hobbing
Advantage: High run-out accuracy and high face run-out accuracy <- 0,003 mm (0.00012"); Additionally the workpiece is being positioned axially by a holder; automatic loading

Gear shaping

Beispiel 4 Hydra-Clamping-Chuck

Actuation: Hand actuated Radially
Mounting: By straight pin
Workpiece: Internal geared wheel
Machine: Gear shaping machine
Application: Shaping of the internal gearing
Advantage: High run-out accuracy<- 0,003 mm (0.00012"); various workpiec mountings with intermediate sleeve possible

Example 5 Hydra-Clamping-Chuck

Actuation: Power actuated axially
Mounting: Flange; cly. centering in Hydra-Clamping-Base-Chuck
Workpiece: Driving flange
Machine: Gear shaping machine
Application: Shaping of the internal gearing
Advantage: High run-out accuracy and high face run-out accuracy<- 0,005 mm (0.0002"); because of the use of a Hydra-Clamping-Chuck as quick change base-chuck, there is a precise and quick tool-change possible

Gear shaving

Beispiel 6 Hydra-Clamping-Arbor

Actuation: Power actuatedaxially by push cap attached to the tailstock
Mounting: Between centers
Workpiece: Gearwheel
Machine: Gear shaving machine
Application: Gear Shaving
Advantage: High run-out accuracy<- 0,003 mm (0.00012"); quick change of workpiece possible

Example 7 Hydra-Clamping-Arbor

Actuation: Power actuatedaxially by push cap attached to the tailstock
Mounting: Between centers
Workpiece: Gearwheel
Machine: Gear shaving machine
Application: Gear Shaving
Advantage: High run-out accuracy<- 0,003 mm (0.00012"); quick change of workpiece possible

Gear grinding

Beispiel 8 Hydra-Clamping-Arbor

Actuation: Hand actuated Radially
Mounting: Flange; cyl. centering in Hydra-Clamping-Base-Chuck
Workpiece: Gearwheel
Machine: Tooth profile grinding machine
Application: Grinding of the tooth profile
Advantage: High run-out accuracy and high face run-out accuracy <- 0,003 mm (0.00012"); because of the use of a power actuated Hydra-Clamping-Chuck as a quick change base-chuck, precise and quick retrofitting possible

Example 9 Hydra-Clamping-Arbor

Actuation: Hand actuated, axially
Mounting: Between centers (Reishauer)
Workpiece: Gearwheel
Machine: Tooth profile grinding machine
Application: Grinding of the tooth profile
Advantage: High run-out accuracy and high face run-out accuracy <- 0,003 mm (0.00012"); several workpieces with different bore tolerances are being ground simultaniously

Example 10 Hydra-Clamping-Arbor

Actuation: Power actuated axially
Mounting: Flange; cyl. centering
Workpiece: Gearwheel
Machine: Tooth profile grinding machine
Application: Grinding of the tooth profile
Advantage: High run-out accuracy<- 0,003 mm (0.00012") with interchangeable intermediate sleeve for different workpiece diameters. High resistance to wear at automatic loading by hard-coating of the sleeve with a surface hardness of the coating of 80HRC.

Gear honing

Beispiel 8 Hydra-Clamping-Arbor

Actuation: Power actuated, axially
Mounting: Flange; cyl. centering
Workpiece: Gearwheel
Machine: "Fässler" honing machine
Application: Gear honing
Advantage: High run-out accuracy and high face run-out accuracy <- 0,002 mm (0.00008"); axial support by tailstock; axially positioned by a holder

Example 12 Hydra-Clamping-Chuck

Actuation: Hand actuated Radially
Mounting: Flange; cyl. centering
Workpiece: Driving flange
Machine: Gear honing machine
Application: Honing of the internal gearing
Advantage: High run-out accuracy and face run-out accuracy<- 0,005 mm (0.0002"). Hydra-Clamping-Chuck mounted into the hone-ring casting. To eliminate the deformation of the driving flange, the pressure of the Hydra-Clamping-Chuck will be monitored by a pressure sensor and will be controlled by "Power Control" -electronic pressure control- from Mytec -Hydraclamp- with interchangeable intermediate sleeve for different workpiece diameters
