Spur Gears By Chongqing Xinchang Gear Industry Co.,ltd.

Our range of Spur Gears are the simplest, and probably most common, type of gear. Their general form is a cylinder or disk. The teeth project radially, and with these "straight-cut gears", the leading edges of the teeth are aligned parallel to the axis of rotation. These gears can only mesh correctly if they are fitted to parallel axles
We manufacture durable and highly efficient spur gears upto 150 mm OD & 3.5 module in steel. These are used in Gear Boxes used in Machine Tools, material handling equipment, Gear Pumps etc.
They connect parallel shafts, have involute teeth that are parallel to the shaft and can have internal or external teeth. They cause no external thrust between gears. They are inexpensive to manufacture and give lower but satisfactory performance. They are used when shaft rotates in the same plane. The main features of spur gears are dedendum, addendum, flank, and fillet. Dedendum cylinder is a root from where teeth extend, it extends to the tip called the addendum circle.
