Product Details

Description

The spur gear is a kind of cylindrical gear, which is formed on the same gear shaft with two sets of different gear shapes, It is equivalent to two helical gears. Not only counteracts the axial force of the gear, but also has the advantages of high bearing capacity and smooth transmission. Double Helical Gear is widely used in the transmission system of heavy machinery.

 

The gear set's teeth is manufactured so that tooth-tip aligns with the opposite tooth-tip, or so tooth-tip aligns with the opposite gear's tooth trough.

Application

Sophia Double Helical Gear 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.
