Spur gears transfer rotary motion between parallel shafts. They have straight teeth which are parallel to the shaft on which the gear is mounted.Spur gears are relatively simple in design and manufacture due to their structure.
Helical gears are used where higher load bearing capacities are required in prime movers and power applications. The teeth are having a inclination ranging from few degrees to up to 30 degrees or more depending on the gear application.
Double helical gears have more than double the contact gear tooth area compared to single helical gears and hence have more load and power transmitting abilities. These gears also operate at low noise levels and high speeds.
We at Marshall Gears are the industry leaders in manufacturing of Large sized Industrial sprocket gears. Sprocket gears are one of the many types of gears that are used for Mining, Conveyor, Dryers, Kilns and other similar applications.
Crowned Gears are necessary for applications where noise is a concern and self alignment is required. Crowning gear teeth reduces noise by alleviating misalignment through either assembly or thrust problems.
