Product Profile of Bevel Gearboxes Gk
Auma manufacturers multi-turn gearboxes to increase the torque or to reposition the output shaft. Auma bevel gearboxes are used for the operation of valves [e.g. gate valves, globe valves]. Salient features are:
Short-time duty S2 - 15 min [Open-close duty]
Intermittent duty S4 - 25 % [Modulating duty]
They can either be operated in:
manual operation directly via handwheel
motor operation [electric multi-turn actuator]
Gearbox is prepared for mounting an actuator flange
Clockwise rotation at the input shaft results in clockwise shaft results in clockwise rotation at the output drive
To reverse the direction of rotation of GK 14.2 - GK 25.2, a reversing gearbox GW 14.1 can be used.
Direction of rotation at the output drive can be reversed for GK 30.2 - GK 40.2.
GK 10.2 - GK 25.2 are single stage gearboxes.
GK 30.2 - GK 40.2 are double stage gearboxes.
Design features:
Torques up to 16,000 Nm
Reduction ratios from 1:1 to 1:22
Output drive types according to ISO or DIN standard
