Helical Gears

We are one of the best Helical gear manufacturer in India which provides precision and quality work across the globe. Helical gear can be used for transmitting motion between parallel shafts as well as between perpendicular (or any other angle) shafts. Helical gears used for transmission at any angle are usually called spiral gears. When gear teeth are cut on a spiral that wraps around the cylinder they are designated as helical. Helical teeth enter the meshing zone progressively and therefore have a smoother action than spur gear teeth and tend to be quieter. In addition, the load transmitted maybe somewhat larger or the life of gears may be greater for the same loading, than within equivalent pair of spur gear conversely, in some cases smaller size Helical gears (compared with spur gears) may be used to transmit same loading. The efficiency of the helical gear set, which is dependent on the total normal tooth load (as well as the sliding velocity and friction co-efficient etc.) will usually be slightly lower than for an equivalent spur gear set. For external parallel axis helical gears to mesh they must have same helix angle but be of different hand.
