Machine Tool Equipment Spiral Bevel Gear

A Spiral Bevel Gear are used to transmit power between shafts that are at a 90-degree orientation to each other. Also, these custom parts are engineered with precision teeth which have a unique curve and are oblique in shape. The teeth have one concave, one convex side, feature a curve and have a spiral angle. This spiral angle is located from the tooth trace and pitch cone, resembling a helix angle that is located in teeth of helical types.
Spiral bevel gears are widely used in petroleum, mining, machine tools, coal mining machinery, motor vehicles, trains, ships, aviation helicopters and other mechanical engineering fields because of their high bearing capacity, low noise, and stable transmission.

As one of the leading spiral bevel gear manufacturers, suppliers, and exporters of mechanical products, We offer spiral bevel gear and many other products.
