Multi-Function Electromagnetic Tooth Clutches
Electromagnetic tooth clutches manufactured by Monninghoff feature precision-machined teeth that can be varied to achieve different performance and functions. Standard teeth are optimised for high torque transmission but many alternatives are possible, for example torque limiting, single-position synchronising and single direction. Clutches and brakes can be manufactured with customised teeth to achieve application-specific performance. Electromagnetic tooth clutches transmit torque without slip. Standard designs are engaged by application of a DC voltage, usually 24V. The transmitted torque and the permissible engagement speed depends on the design of the engagement teeth. Monninghoff uses one hardened bronze tooth ring for the clutches. This prevents magnetic flux passing through the teeth and improves the engagement and wear characteristics. Both stationary field and slip-ring designs are available - the most popular and adaptable version has a bearing-mounted stationary field coil...
