6.1 Type overview Type V – Standard bevel gearboxes Gear ratios: i = 1:1 to 6:1 Maximum output torque: 5400 Nm 9 gearbox sizes with edge lengths of 065 to 350 mm Low-backlash construction < 6 angular minutes possible Housing made of grey cast iron or steel Type VS – Type V with step-up ratio Gear ratios: i = 1:1.5 and 1:2 Maximum output torque: 1200 Nm 6 gearbox sizes with edge lengths of 090 to 260 mm Low-backlash construction < 10 angular minutes possible Larger shaft diameter (N2), slowly rotating Housing made of grey cast iron or steel Type VL – Type V with flange Gear ratios: i = 1:1...

A bevel gearbox enables alternatively stepping-down or stepping-up. The axles intersect in the gearbox in an angle of 90°. The edge length of the housing is reflected in the gearbox size (example: V 120 - housing edge length 120 mm). 6.2.1 Toothing ATEK bevel gearboxes have gear sets with high-quality spiral toothing made of hardened carburised steel. A gear set comprises one bevel pinion (small number of teeth / small diameter) and one bevel gear (large number of teeth / large diameter). Gear sets with spiral toothing offer the advantage of very favourable engagement factors (high meshing...

6.2.7 Efficiency The achievable efficiency depends on rotational speed, torque, installation position, sealing, and lubricant type. With gearboxes having only one gear set, an efficiency of 97% can be achieved. With gearboxes having several gear meshings, an efficiency of 94% can be achieved. The efficiencies specified in the tables relate to the permissible nominal load and are guidance values for run-in gearboxes at operating temperature with standard sealing. 6.2.8 Lubrication With the bevel gearboxes, different conditions for the lubrication will arise depending on gearbox size,...

6.2.9 Vent filter If venting is required (B1 or C1) the gearboxes will be delivered with a vent filter. The vent bores will be equipped with screw plugs for transport. The vent filter will be enclosed as a separate item and must be mounted in the intended position prior to commissioning. An elbow may be required. Please adhere to the operating instructions! The position of the filter will be specified in the order documents. Please refer to the following table for the position of the filter. The meaning here, for example: /B1-E4 = oil viscosity 220; vent filter on side 4. 6.2.10...
