Noncontact clutch cuts out maintenance

Rimtec product story

A novel barrier clutch enables maintenance free quick connections for flexible manufacturing by transmitting torque and speed with no contact.
Rimtec's newly developed MDC series permanent magnet synchronous clutch is used to transmit torque from a motor to a flexible fixture used to automate machining of parts for the automotive industry.
Several independent fixtures can index their way over to a single motor with a noncontact magnetic coupling.
The motor actuates the fixture's clamping motion, providing an adequate clamp force for machining.
The fixtures then index their way into the respective machining environment.
While a part is in the machining centre, more parts are being indexed over to the drive motor for clamping.
The MDC style uses samarium cobalt permanent magnets assembled on two discs while keyless clamps attach the discs onto the respective shafts.
As the clutch has no touching or wearing components, all maintenance has been eliminated.
The MDC series is available from 2-30Nm and can be specifically balanced for high speed.
The barrier in between the two halves is a nonmagnetic material thus enabling one half to be completely enclosed for hazardous, food grade, or chemical environments.
For larger sizes, the MSV style is available upwards of 1000Nm.
