Bevel gears

• Bevel gears are useful when the direction of a shaft’s rotation needs to be changed
• They are usually mounted on shafts that are 90 degrees apart, but can be designed to work at other angles as well
• The teeth on bevel gears can be straight, spiral or hypoid.
• Bevel gears with equal numbers of teeth and shaft axes at 90 degrees are called miter gears.
• locomotives, marine applications, automobiles, printing presses, cooling towers, power plants, steel plants, railway track inspection machines, etc.

• WORM AND WORM GEAR

• Worm gears are used when large gear reductions are needed. It is common for worm gears to have reductions of 20:1, and even up to 300:1 or greater
• Worm gears are used widely in material handling and transportation machinery, machine tools, automobiles etc
