Helical Beam Coupling

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.

Helical beam coupling.

Helical flexible couplings are used for applications in aerospace aviation medical science military energy automation. 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. The flexible beam coupling was invented by helical products in 1958 when george sabadash conceptualized a single piece flexible coupler or beam coupling. These spiral beam couplings are longer in length and can tolerate greater radial and angular shaft misalignment.

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. 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. At the same time the helical cut pattern continues to provide excellent torque capabilities and low wind up. Also known as helical beam couplings.

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. Acetal couplings are lightweight and corrosion resistant. The rest is history as sabadash was joined by a group of engineers to perfect and market the world standard in flexure 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.

Often used for light duty encoder and stepper drive applications they allow zero backlash no play and never need lubrication. 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. Six beam couplings have two sets of these beams separated by a solid member. Available in stainless steel or aluminium as standard with both metric and imperial bores sizes stocked ready to be delivered.

Once the endless possibilities of a single piece flexible shaft coupling were fully realized the evolution began. Heli cal shaft couplings are an essential connection in any rotary device without loss of registration under load. The flexible beam coupling by helical products. How coils determine helical beam coupling performance the performance capability of each helical flexible shaft coupling is determined by factors such as.
