    Spur Gears


    Spur Gears (straight-cut gears) are the most common type of gear. Spur Gears transfer motion and power from one shaft to another. Spur Gears are very efficient and can be customized to fit all your specifications.

    Bevel Gears


    Bevel Gears are used to connect shafts whose axes lie at an angle to each other. Bevel Gears are most often mounted at a 90-degree angle, but can be designed to work at other angles as well. There are two types of Bevel Gears, Straight Bevel Gears and Spiral Bevel Gears.

    Straight Bevel Gears


    Straight Bevel Gears are the most applied type of gear and have straight teeth that are cut along the pitch cone to intersect with the shaft axis.

    Spiral Bevel Gears


    Spiral Bevel Gears have helical teeth causing less vibration and noise. Spiral Bevel Gears are used in vehicle transmissions and other machinery requiring a drive to be turned 90 degrees.

    Worm Gears


    Worm Gears are an arrangement consisting of a toothed wheel worked by a spiral thread that engages with the toothed wheel. Worm Gears gears are great for machines like conveyor systems due to the shallow angle on the worm to keep it in place. At WDB we can make worm gears at any angle to precisely fit your specifications.

    Helical Gears


    Helical Gears are designed with teeth that are curved into a helix shape, which allow for a total contact ratio used to improve vibration and noise. There are two types of Helical Gears, Left-Handed Helical Gears and Right-Handed Helical Gears. These gears transmit energy through axial configurations, parallel and perpendicular. WDB can custom manufacture your Helical Gear application to exceed your satisfaction.

    Left-Handed Helical Gears


    Left Handed Helical Gears teeth lean to the left when placed flat on a horizontal surface.

    Right-Handed Helical Gears


    Right Handed Helical Gears teeth lean to the right when placed flat on a horizontal surface.

    Herringbone Gear


    Herringbone Gears are customized with a side-to-side combination of two Helical Gears of opposite hands. These can handle a great axial load. The groves in Herringbone Gears are shaped to look like a V. We carefully engineer and manufacture Herringbone Gears to assure they can handle the heaviest of loads with the most power necessary for your application.

    Rack and Pinion


    Rack and Pinion gears are straight teeth cut into one square or round surface and operate with a pinion. Rack and Pinion Gears are typically used for steering to convert the circular motion of the steering wheel into linear motion required to turn the wheels.
