Ideal for use even with high loading, these gearboxes have a sturdy grey cast iron housing, hardened bevel gears lapped in pairs with spiral toothing and amply dimensioned anti-friction bearings for optimum running quietness and a high degree of transmission accuracy.
Spiral bevel gears have the benefit of very favourable meshing characteristics (meaning a high contact ratio) and curved teeth considerably more resistant to distortion than straight or helical teeth.
A further benefit of these gearboxes is their relative insensitivity to elastic distortion of wheels, shafts and bearings. ATEK bevel gearboxes are thus able to transmit even extreme shock loads.
Twelve different standard models are available. 22 further variations are possible as multi-shaft gearboxes. ATEK bevel gearboxes are lubricated for life and maintenance free. They can be used in all operating positions and can be provided with mounting holes on all sides. Covers and flanges are generally provided with mounting holes.
The following standard transmission ratios are available: 1 - 1.5 - 2 - 3 - 4 - 5 and 6:1. All transmission ratios are mathematically precise. The gearboxes can be used for gearing down and gearing up. Special transmission ratios are available. Please enquire for further information.
All gearboxes are available as a complete drive with electric motors or suitable for attachment of IEC motors.
