Helical gears can be machined
Helical gears also connect parallel shafts, but the involute teeth are
cut at an angle (called the helix angle) to the axis of rotation. The
two mating helical gears must have equal helix angle but opposite hand.
These gears are found in automotive transmissions, and any application
requiring high speed rotation and good performance.
Due to continuous tooth mating, helical gears run smoother and more
quietly than spur gears. They also have a higher load capacity due to
there greater cross sections.
We are able to manufacture both single and double helical gears from 3 DP to 30 DP and up to 1800mm diameter. Face lengths of up to 600mm are possible with helix angles of up to 60 degrees all depending on the configuration of the gear. Accuracies of up to AGMA Class 6 are possible on our hobbing machines while AGMA Class 10 can be achieved with our grinding facilities.
