Helical Gears

A helical gear has teeth in form of helix around the gear. Two such gears may be used to connect two parallel shafts in place of spur gears. The helixes may be right handed on one gear and left handed on the other. The pitch surfaces are cylindrical as in spur gearing, but the teeth instead of being parallel to the axis, wind around the cylinders helically like screw threads. The teeth of helical gears with parallel axis have line contact, as in spur gearing.
This provides gradual engagement and continuous contact of the engaging teeth. Hence helical gears give smooth drive with a high efficiency of transmission. We have already discussed in Art. 28.4 that the helical gears may be of single helical type or double helical type. In case of single helical gears there is some axial thrust between the teeth, which is a disadvantage. In order to eliminate this axial thrust, double helical gears .

Helical Gears 

The helical gears and industrial helical gears are those type of gears having the teeth at any angle other than 90 degrees to the face of the gear. We at malkar is having special set up for fine pitch gear & pinions production on MIKRON GEAR HOBBING MACHINES. Malkar has specialization in manufacturing high helix angle gears for spedo drive. Assembly used spedo meter drive for two wheeler as well as four wheeler
