Helical Beam Coupling

Helical flexible couplings are used for applications in aerospace aviation medical science military energy automation.

Helical beam coupling. Acetal couplings are lightweight and corrosion resistant. The flexible beam coupling was invented by helical products in 1958 when george sabadash conceptualized a single piece flexible coupler or beam coupling. The flexible beam coupling by helical products. The rest is history as sabadash was joined by a group of engineers to perfect and market the world standard in flexure beam couplings.

Our helical beam coupling was developed especially for drive systems with small dimensions and low torques where a high degree of torsional rigidity is required. Once the endless possibilities of a single piece flexible shaft coupling were fully realized the evolution began. This design utilizes a single piece of material and becomes flexible by removal of material along a spiral path resulting in a curved flexible beam of helical shape. A beam coupling also known as helical coupling is a flexible coupling for transmitting torque between two shafts while allowing for angular misalignment parallel offset and even axial motion of one shaft relative to the other.

How coils determine helical beam coupling performance the performance capability of each helical flexible shaft coupling is determined by factors such as. Also known as helical beam couplings. Helical beam shaft couplings a single piece construction zero backlash constant velocity shaft coupling that simultaneously compensates for angular parallel and skewed shaft misalignments. In 1958 helical invented the beam style flexible shaft coupling by taking a novel concept and developing the method to generate the versatile heli cal flexure into a piece of stainless steel.

These spiral beam couplings are longer in length and can tolerate greater radial and angular shaft misalignment. Available in stainless steel or aluminium as standard with both metric and imperial bores sizes stocked ready to be delivered. At the same time the helical cut pattern continues to provide excellent torque capabilities and low wind up. Six beam couplings have two sets of these beams separated by a solid member.

Heli cal flexure flexible couplings are machined from single piece homogenous high strength materials into helical curved beam configurations which eliminate elastomeric elements like rubber bushings spiders rubber discs and pads. These flexible couplings are shorter than the f series six beam couplings and conform to industry standard lengths fitting into confined spaces and allowing for easy retrofits in existing equipment. The optimised slot structure of the walther flender helical beam coupling guarantees higher torques and improved torsional rigidity when compared to similar couplings and thus offers. Heli cal shaft couplings are an essential connection in any rotary device without loss of registration under load.
