SYNTEX® backlash-free ball catch overload system

Overload protection via special disk spring

Whether with a toothed belt pulley, mounting flange or in combination with tried-and-tested coupling models - SYNTEX® provides optimum overload protection for your drives. The special perforated disk spring sits at the heart of this overload protection system. The compact design allows for easy integration in the drive.

Highlights

• Backlash-free, torsionally rigid overload protection
• High response accuracy, even after a long operating period
• Easy assembly and torque adjustment
• Large range of variants thanks to modular system
• Maintenance-free and insensitive to oils and greases
• Freely selectable or synchronous re-engagement
• Automatically ready for operation again

Functional description

The backlash-free overload system operates with a form fit. The perforated disk spring is used for the transmission of the torque. Upon exceedance of the torque set, relative motion between drive and output occurs. At the same time, the transmissible torque decreases. The ball bearings stored in the perforated disk spring leave the depressions of the disk spring. Upon elimination of the overload, they once again re-engage in the depressions of the disk spring.

Power range

• Overload protection up to 400 Nm

Application area / utilisation

• Reversing duty
• Packaging machines and machine tools
• Linear and servo drives
