BEVELGEAR Competence and Performance

BEVEL GEAR General Advantages of Spiral, Hypoid and Zerol Bevel Gears ■ High level of coverage due to the fact that several teeth are meshed simultaneously ■ Noise and oscillation damped even at high peripheral speeds ■ Resistant to elastic deformation of gears, shafts and bearings ■ Gear sets can be assembled in your preferred direction of rotation ■ Circular arc gear teeth are more resistant to bending than straight and oblique gear teeth ■ > 97% efficiency depending upon layout and lubrication ■ Very gentle transmission even at high-speed operation and under heavy load ■ Due to convex...

BEVEL GEAR Examples of Gear Tooth Parts High-transmission hypoid gear set i=30:1 with typical shaft offset. Spiral bevel gear pair with 45° shaft angle. The smaller the bevel gear, the greater the know-how necessary.

BEVEL GEAR Driven by your requirements Our engineering and special manufacturing techniques have helped us become precision manufacturer of bevel gear systems and bevel gearboxes for more than 60 years, as well as specialist in special gearboxes. Our expertise also extends to a special in-house developed workflow management system: for optimal processes between all areas involved and the customer. Our quality management system thus guarantees highest quality and cost certainty. For us, individual solutions are standard. And instead of offering expertise that‘s confined to certain areas,...

■ The housing and all components must be cleaned. ■ Attention should be paid to the bearing manufacturers guidelines when assembling the rolling bearings ■ Lapped gears must be assembled in pairs. ■ The radial and axial contact surfaces should be inspected for radial and axial runout. ■ The pinion should be assembled at the correct distance. ■ The gear should be assembled with the recommen ded backlash. ■ The pinion and gear must be secured against axial thrust in both directions. ■ The tooth contact pattern should be inspected. ■ Care should be taken that the toothed gears and bearings are...
