Perfect Overload Protection
The market leader mayr power transmission provide the largest variety of torque limiting clutches
Incorrectoperation, software and hardware errors in control units and external mechanical influences are the most frequent causes of collisions in machinesandsystems . The consequences are costly damages and production downtimes. In most cases, mechanical torque limiting clutches are able to offer reliable protection from such overload damages. However, the clutch must also be the optimum device for the respective application requirements. Only a few suppliers can provide the wide range of products needed. For 50 years, mayr power transmission have been developing and manufactur ing such protect ion elements, and as market leaders can offer their customers the widest range of products.
- ROBA-Co-Pro : Frictionally locking clutches are typical representatives of the load holding torque limiting clutches. If a blockage occurs the drive element slips through with the set torque.
Accurate torque limiting allows torque limiting clutches to prevent loads on components in machines and systems from exceeding the permitted values. Due to this advantage, numerous demands on modern machine designs can be realised without taking risks. Design safety factors can be reduced. This generates optimally dimensioned machines with low mass moments of inertia. Such machines then require smaller drive motors and gears. Therefore, the use of torque limiting clutches pays off for the machine manufacturer by allowing material and cost savings in machine dimensioning.
Torque limiting clutches offer the largest benefit for production companies. No machine is absolutely collision-proof. The risks can be reduced but not entirely avoided. They even occur occasionally on machines with intelligent control and monitoring units. Users of CNC machines have confirmed that around two collisions per machine are not unusual, even for experienced operating personnel. They are caused by operating errors, software and hardware errors in the control system and external mechanical influences. Collisions may result if for example defective position sensors report an incorrect actual position, tools are incorrectly clamped or foreign objects get into the machining area. The consequences are high repair and spare parts costs, downtimes, production standstill, turnover losses and loss of image due to delayed lead times.
