Method and apparatus for improvement of involute and lead error in powder metal gears |
摘要 |
<p>Gears, particularly spur gears, are produced by powder metal techniques with minimal lead line error and eccentricity, which gears are preformed from powder metal, sintered, hardened and thereafter have their involute surfaces regenerated by a hard hobbing process to provide gears having aligned involute surfaces between adjacent gear teeth and, between each gear tooth and the gear center line. <IMAGE></p> |
