Grinding double helical gears used in heavy load equipment, accuracy DIN7. 

The combination of left-hand and right-hand helical gears with the same twist angle is called a double helical gear. Double helical gears transmit rotational motion between two parallel axes.

Double helical gears have all the advantages of helical gears, namely being strong and quiet, with the added advantage of being able to counteract thrust by combining helical gears with left- and right-hand rotation.
