Description

Herringbone gears conduct power and motion between non-intersecting and parallel axis ,each center might or might not has center groove,and each group consist of  two opposite helices.  The two helix angle come together in the center ,and the shape of herringbone gear is similar as the letter 'V'.

All kinds of bearings are used as support and limit for the shafting  in real work. It is very important to choose the type of bearing to ensure the correct meshing of the herringbone gear transmission.The axial movement of the shafting is completely limited  If the bearing with the restricted axis moves, and double helical gear can not be meshed correctly: therefore,in the shaft, the position of the bearing should be adjusted and fixed firstly.

Application

Double Helical Gear Transmission is mostly used on heavy machinery. High precision double helical gears is mainly used  in power transmission.They utilize curved teeth for efficient,high capacity power transmission.This reduced pulsation,because they are highly used for extrusion and polymerization.
