SEMO Clutch - Brake

The Ortlinghaus SEMO Brake

The SEMO-Brake is a backlash free, spring-applied brake based on a totally NEW, patented principal of operation. This brake can be released using electromagnetic, pneumatic, or hydraulic force.

Application

The Ortlinghaus SEMO-Brake can be used in all types of applications in which the brake primarily serves as a statically applied holding brake. However, this brake can also be occasionally used in a dynamic mode as an emergency brake.

Advantages of the SEMO concept include:

  • No drag or idling torque
  • Can be installed in a horizontal or vertical position or at any angle
  • Completely backlash free
  • Very compact design
  • No maintenance required for setting or maintaining air gap
  • There is no air gap to maintain therefore machining tolerances of adjoining parts are less demanding
  • No axial loading on adjoining parts
  • Self adjusting as it wears with no reduction in the brake torque

Design Concept

The SEMO concept is based on using mechanical leverage to amplify the force of the friction linings against the respective opposing friction surface. This mechanical advantage results in a very high torque to physical size relationship.

Due to its unique design, the friction radius of the brake is almost at the very outer diameter of the unit, which makes it a very compact design concept.

The torsionally stiff actuation fingers, that have the friction material attached to them, guarantee that the brake will have zero backlash.

Flexibility of Concept

This patented design can be used for clutch or brake applications using various actuation methods.
