SELECTING THE RIGHT MITER AND BEVEL GEARS
To select the correct bevel or miter gears for any application, the following must be known:
• Horsepower required to be transmitted by gears
• Pinion (driver – high speed) shaft RPM
• Gear (driven – slow speed) shaft RPM
• Ratio required
• Mounting distance of gear and pinion
• Space limitations (if any)
• Duty cycle
NOTE: Duty cycle refers to the operating conditions. The bevel and miter gear ratings in your Catalog should be satisfactory for gears that are properly mounted,properly lubricated, and carrying a smooth load (without shock) for 8 to 10 hours a day.
Bevel or miter gears keypoints
• Miter gears are always 1:1 ratio
• Bevel gears range from 1.5:1 to 6:1 ratio
• Miters and bevels are for 90º applications only
• Spiral miter and bevel gears are more suitable for higher speed applications
• Miter and bevel gears are measured on the large end of the tooth when using a gear gauge
• Gear miter and bevel gears are made to the Coniflex™ tooth form
