Schürmann-Verzahnung / Mating surface

Discipline: Product

The invention deals with the design for a mating surface for axes, shafts and flanges. The connecting element is characterized by semi-circular, parallel running slots and webs. These characteristics lead to a cost-effective manufacturing. The geometric principle of the invention is based on semicircles with different epicenters in order to make use of the whole front face. The Schürmann-mating surface element competes against the Hirth-mating surface element. The invention is of equal value but it represents an explicitly cost-effective alternative. It features space-saving more effective uses compared to a simple slot and key joint.

This unconventional product is highly technical, but the developer has clearly thought like a designer at the same time. The wave form of the serration is reminiscent of natural shapes. The machine is extremely stable, as the load is distributed across the whole surface equally. This product is space-saving and more effective than its conventional equivalents, yet also more effective and economical. A great design!
