We are in manufacturing of standard and custom made gears and gears boxes in hardened and ground condition for material handling, process equipment and general purpose. We manufacture helical gears which connect parallel shafts but the involute teeth are cut at an angle to the axis of rotation. The two mating helical gears must have equal helix angles but at the opposite hand. They run smoother and more quietly. They have higher load capacity and are more expensive to manufacture and create axial thrust. Helical gears can be used to mesh two shafts that are not parallel and can also be used in a crossed gear mesh connecting two perpendicular shafts. They have longer and stronger teeth. They can carry heavy loads because of the greater surface contact with the teeth. Their efficiency is also reduced because of longer surface contact. The gearing is quieter with less vibration.
