Universal Gear Diaphragm Chuck

Forkardt’s Universal Gear Diaphragm Chucks are ideal for longer run applications with infrequent changes. The UG diaphragm chucking system adapts to many different gear configurations, requiring minimal top tooling. Changeover from one gear to another is simple and can be accomplished in minutes. Diaphragm chucks contain no moving, wearable parts, eliminating downtime and maintenance costs.

The Universal Gear Diaphragm Chuck provides consistent and controlled accuracy on every run. The UG chuck features pull back action against fixed stops for positive location. The inherent diaphragm chuck mobility permits „float“ to compensate for gear spacing errors due to machining or heat treatment distortion.

Applications

• Gear families including Sun, Ring, Pinion and Output gears
• Spur and Helical gears
• Hard turning and grinding operations
• Automotive CG Joints

Advantages

• No sliding parts means no friction or wear, reducing maintenance cost and down times.
• Inherent strength and accuracy of spring steel is used to achieve chucking pressure on internal or external surfaces, ensuring consistently controlled concentricity.
• Acheive consistent and controlled accuracy on every run
• Pull back action against fixed stops for positive location
• Inherent diaphragm mobility permits “float“ to compensate for gear spacing errors due to macining or heat treatment distortion
• Simple gear changeover reduces set up time
