Designs and Special Solutions
Our new Preloaded Double Pinion enables a back-lash-free drive in connection with a rack. A flange acc. to ISO 9409-1 connects the Preloaded Double Pinion with a gearbox. The Preloaded Double Pinion is available as either helical or straight teeth type.
In addition to our standard range shown above, we offer customized Flange Pinions as well. Parameters such as module or number of teeth can be chosen freely to suit customers' requirements. Please send us your specific configuration in order to receive an accordant offer.
The teeth of the master-gears are case-hardened and ground. The hub and the bore will be machined according to the operating range. Thereby the delivery time is shorter and the spectrum of applications will be enlarged. Our Master-Gears are available in modules 2 - 6.
Our Bevel and Spur gears made of acetal resin (Hostaform C) are manufactured by injection moulding. Their relatively high hardness and low friction coefficient gives them particulary good wear properties. Their running characteristics are not effected by air humidity or lubricating oil. They operate satisfactorily in water and are resistant to many chemicals.
Under normal loads and working conditions they can operate at temperatures between -40° C and +100° C.
