工件承载器装置
摘要：
一种工件承载器(2)包括能够围绕驱动轴线(4)进行旋转的旋转框架(3)和驱动部件(22)。旋转框架(3)能够受到马达(6)的驱动，并且承载着多个围绕驱动轴线(4)分布以便能够围绕保持器轴线进行旋转的工件保持器(13)。在固定件上面安装在驱动部件(22)中的是与固定不动的中心轮(21)和传动部件(26)的环形齿轮(27)相啮合的小齿轮(25)，输出点(29)位于所述小齿轮的中心，所述输出点距驱动轴线(4)的距离为偏心距。所述传动部件(26)上面的驱动孔(28)同样距保持器轴线的距离为偏心距，工件保持器(13)的驱动销(19)通过所述驱动孔(28)伸出。在旋转框架(3)进行旋转时，驱动部件(22)围绕驱动轴线(4)绕转，并且还施加在传动部件(26)上面，所述传动部件也随着旋转框架(3)进行旋转，偏心运动使得输出点(29)环绕驱动轴线(4)，结果是工件保持器(13)实现了相对应的旋转。
摘要（英）：

A workpiece carrier (2) comprises a rotary frame (3) and a driving part (22), both of which are rotatable about a driving axle (4). The rotary frame (3) can be driven by a motor (6), and carries a plurality of workpiece holders (13) distributed around the driving axle (4) so as to be rotatable about holder axes. Mounted in the driving part (22) on a mount is a pinion (25) which engages with a stationary central wheel (21) and a ring gear (27) of a transmission part (26), at the centre of which lies an output point (29) which is at a distance of an eccentricity from the driving axle (4). Driving apertures (28) on the transmission part (26), through which driving pins (19) of the workpiece holders (13) project, are also at the distance of the eccentricity from the holder axes. On rotation of the rotary frame (3), the driving part (22) revolves about the driving axle (4) and additionally imposes on the transmission part (26), which rotates concomitantly with the rotary frame (3), an eccentric motion such that the output point (29) circles round the driving axle (4), as a result of which corresponding rotation of the workpiece holders (13) is effected.
