Steel Helical Gears


Custom Helical Gears


HELICAL GEARS, when used on parallel shafts, are similar in usage to spur gears. Where velocities exceed 1000 feet per minute, helical gears provide a stronger, smoother running gear train.


This type of stock gearing is furnished in 45° helix angle. Materials available are hardened steel, steel, stainless, aluminum, bronze, nylon and non-metallic (phenolic).


End Thrust is developed by helical gears, but this may be overcome through the use of thrust washers or other suitable types of thrust bearings.

Our helical gears come in alloy or mild steel options. Detailed below are ground axial helical gears and hobbed normal helical gears. 


① The allowable torques shown in the table are calculated values according to the assumed usage conditions. 

② The backlash values shown in the table are the theoretical values for the backlash in the normal direction of a pair of identical gears in mesh.

③ These gears produce axial thrust forces. 

④ Right handed and left handed helical gears in the same module are designed to mesh as a pair, but SH gears are not interchangeable with other type helical gears.
