Verfahren und Einrichtung für die Oberflächenhärtungsbehandlung von Stahlkugeln für ein Kugellager |
摘要 |
An apparatus for surface-hardening steel balls includes a container having projections protruding inwardly from and extending longitudinally along an inner wall; a support shaft having projections extending outwardly from and longitudinally along the support shaft; a container driving mechanism which rotates the container in one direction; and a support shaft driving mechanism which rotates the support shaft in an opposite direction. In operation, the container's projections transfer the balls from a lower portion of the container to a higher portion where the balls are dropped to the lower portion while the support shaft's projections strike the steel balls when the steel balls are dropping to the lower portion. |
