Overview
Mfr description
M1221A GEAR MITER
- All Martin miter and bevel gears are generated with the "coniflex" tooth form.
- A slight misalignment of gears is permissible because of the localized tooth bearing running lengthwise along the gear tooth.
- Martin stock miter gears are manufactured from 1144 Carbon steel
- Hardened miter gears have approximately 50% more horsepower capacity and provide greater gear wear than untreated gears.
- All Martin miter gears are cut with the 20° pressure angle system. They will not operate with any other pressure angle system.
- The use of a straight mineral oil as a lubricant is recommended for most miter gear applications.
- All standard stock miter gears must be mounted at right angles (90 degrees) for proper tooth bearing
