Helical gears are cylindrical disks that have involute formed teeth cut to their
face at an angle. XLT share helical gears are quiet, compact and
economical. They are suitable wherever you require high- speed rotation
including in machine tools, speed reducers and other industrial machinery. Our
helical gears are offered in alloy steel and carbon steel, with many
configurations of modules and numbers of teeth. All of the helical gears that we
offer allow for secondary operations such as opening the bore, adding of
keyways, adding of tapped holes, but only a few allow for the reduction of the
hub diameter to be performed. Our offering also includes products which have
already had some of these secondary operations completed.
Helical gears
belong, by the gear shaft classification, to parallel axes gears and are
cylindrical gears in which the teeth are twisted as a helix line.
The
shape of a helical gear is given by stacking infinitesimally thinly sliced spur
gears and twisting them uniformly around the shaft. Differentiating by the
direction of the twist, the right- hand and the left- hand helical gears are
obtained. Also, for a pair of helical gears, the twist angles are the same but
are of the opposite hands.
