Abstract: |
This invention discloses a kind of integral whole gemel device, including to establish one by one in order in the turn-over axis in stalk line direction of, universal gemel upper axis, universal gemel below axis, a round nut, a wreath ring, round turning axis bearings, round turning axis bearings cover and round turning axis. Heading up the two axis of that universal gemel upper axis ,setting cross axis bearings and the block cover of cross axis respectively, and the lock pin device used to carry out the functions of turn-over gemel, universal gemel or the ball gemel. This organization can used in the material that needs to recompose, reducing the quantity of gemel and lowering the cost, to satisfy the demand that the organization changes quickly; And the ball gemel compared with traditional ball gemel it is more easy to mark the revolving center, this is the characteristics. |
