Overload & Coupling Torque limiters

torque limiting device

In order to overcome the problems associated with conventional round shearpins, Howdon developed a wedge shaped shearpin introducing a completely new concept for torque limiters. A comprehensive range of overload clutches have been produced using the Wedgegard™ Shearpin Torque Limiter, and are successfully employed worldwide protecting conveyor drives, sewage and process pumps, road tanker PTO drives, steel & paper mills, and marine propulsion just to name a few.

Building upon the WedgegardShearpin Torque Limiter, Howdon Power Transmission continues to develop outstanding torque limiters for mechanical drive overload problems met in the increasing demands of today’s process plant requiring fail-safe, dependable overload protection.

Advantages:

  • Easy access - drive reset in mere minutes
  • Wedge-shaped construction gives maximum rigidity with no backlash, making this product ideal for indexing or reversing drives. 
  • Clamping screws give positive axial location. Shear neck cannot be displaced from correct position between flanges.
  • Equal load sharing with multiple pins on high-torque drives. Very high capacity within compact dimensions.
  • Shear necks are standardized and color coded giving safe, tamper-proof repeatability. Spare Wedgepins are extremely economical. 
  • Fail-Safe under all conditions. No affected by changes in temperature or humidity. Ability to release is not dependent on mechanism lubrication

Available Designs:

  • Gear Couplings
  • DIN Universal Joints
  • SAE Universal Joints
  • Sprockets
  • Sheaves
  • ...and more!
