The more comprehensive the automation of machines and installations, the safer their operational function needs to be. Blockages or overloads should never be cause for the destruction of operationally important components. Stoppages must be kept to a minimum so that the production process continues as quickly as possible and without costly repairs. After all, shorter downtimes mean higher productivity.
RINGSPANN Overload Clutches are mechanical safety devices which disconnect the output from the input when a preset limit value has been reached. Thus they protect against damage and stoppage times caused by overload.
For over 40 years RINGSPANN has manufactured Overload Clutches with an excellent track record in the most diverse applications. Today RINGSPANN offers a comprehensive range of positive and friction Overload Clutches.
RINGSPANN supplies not only Overload Clutches but can also offer comprehensive advice and service. RINGSPANN provides the security you need.
Torque Limiters
Positive SIKUMAT® Torque Limiters are used as precision safety devices in installations and machines. The unsurpassed variety of working principles offer optimal solutions to every type of application:
- SIKUMAT® with screw faces for particularly heavy-duty operating conditions,
- SIKUMAT® with double rollers for high consistency of the limit torque over the duration of the operating period,
- SIKUMAT® with balls for very high response accuracy as well as for backlash free transmission of torque and
- SIKUMAT® with single rollers for universal application conditions.
Friction Torque Limiters
Friction Torque Limiters are available in two designs:
- RIMOSTAT® Torque Limiters for high torque consistency even during frequent slipping and
- Belleville Spring Torque Limiters for particularly cost effective solutions.
Force Limiters
RlNGSPANN has designed a series of Force Limiters, outstanding in that forces up to a certain size can be transmitted in both directions completely free of play and rigid. On exceeding the pre-set disengaging force the power of the force is interrupted and the output part is no longer driven. After the overload has been cleared the driving part and the driven part are aligned towards each other and the Force Limiter re-engages automatically.
The Force Limiter can be fitted with non-contact proximity switch to give early warning of reaching a certain force, or disengaging signal.
