American standard bevel gear Miter Gears
20° Pressure Angle
1:1 ratio. They are working where high efficiency is required. Only miters of the same number of teeth, pitch, and pressure angle is operating together. More than two miters is working in sets, as in a differential.
The thrust of Miter Gears causes the gears to separate; there- fore, ball bearings or roller bearings should be used rather than sleeve bearings. Provisions should be made using thrust bear- ings to absorb backward thrust.
All standard stock Miter Gears must be mounted at right angles (90 degrees) for proper tooth bearing.
All Miter and Bevel Gears are generated with the Coniflex tooth form. A slight misalignment of gears is permissi- ble because of the localized tooth bearing running lengthwise along the gear tooth.
The mounting distance must be held in order to maintain prop- er backlash between gears. This will also insure that the ends of the gear teeth will be flush with each other. The use of a straight mineral oil as a lubricant is recommended for most Miter Gear applications.
Stock Miter Gears are making from .40 carbon steel.
- The “M” Series: furnished unhardened with plain bore.
- The “HM”Series: furnished hardened teeth with plain bore.
- The “HMK” Series: furnished hardened teeth with key way and setscrew for installation on the shaft.
Hardened Miter Gears have approximately 50% more horse- power capacity and provide greater gear wear than untreated gears.
All Miter Gears are cut with the 20° pressure angle sys-tem. They will not operate with any other pressure angle system.
