11. Load calculation of gears - NSKSubscript 2: Driving gear. In the case of double-helical gears, thrust of the helical gears offsets each other and thus only tangential and separating forces act. For.helical gear axial force,Helical Gears - nptelHerringbone or double helical gear shown in Fig. 11.4 can be two helical gears with opposing helix angle stacked together. As a result, two opposing thrust.
