Friction pneumatic clutch 'DSF/TF/AP'

Product catalog summary

Introduction
Pneumatic clutches are designed for torque transmission up to 30,000 Nm and a maximum bore of 120 mm. They are used for complete engagement and disengagement of transmissions, suitable for long periods.

Specifications
- DSR/F/AP: Torque range from 7 to 30,000 Nm, max bore 120 mm.
- DSR/F/AP + GEC: Compact coaxial connection, max bore 180 mm.
- DSF/TF/AP: Friction motion transmission, torque range from 3 to 875 Nm, max bore 65 mm.
- DSF/TF/AP/TAC: Simple coaxial shaft connection, torque range from 3 to 875 Nm, max bore 80 mm.

Assembly Examples
Models like DSF/TF/AP with plate wheel are used for parallel shaft transmission, offering simple calibration and torque limiter functions. They allow torque variation while in motion through pressure regulation and ensure low residual torque after disengagement.

Applications
These clutches are suitable for machines with variable torque requirements, test benches, coilers, uncoilers, and systems requiring tension maintenance or overload protection.

Technical Data
Friction pneumatic clutches offer constant torque calibration and are available with special friction rings. They can stop transmission after overload with a torque range of 3 – 875 Nm and a max bore of 65 mm.

Dimensions and Technical Details
Detailed dimensions and technical specifications are provided for various sizes, including torque transmission capabilities and maximum speed.

Additional Information
Various versions are available on request, including those with ball bearings, proximity sensors, and automatic re-engagement features. Pneumatic clutches can be controlled via adjustable pressure regulators, solenoid valves, or PLCs.

Order Example
Ordering involves specifying the torque limiter size, model, version, and finished bore, along with the coupling model and locking type.
