## Abstract

A workpiece carrier has a base frame, a shaft surrounding a drive axis and a workpiece carrier and includes a rotary frame mounted on the base frame so as to be rotatable about the drive axis, workpiece holders mounted on the rotary frame so as to be rotatable about holding axes, a driving part with a holder mounted so as to be rotatable about the drive axis, a transmission part operationally connected to the rotatably mounted workpiece holders, and an intermediate gear attached to the rotatably mounted holder. The intermediate gear is connected to the shaft and to the transmission part in such a way that the transmission part engages with the driving part so as to be rotatable about an output point that is spaced apart from the drive axis by an eccentricity.

## Claims

### Claim 1

A workpiece carrier device having a base frame (1), a shaft (20) surrounding a drive axis (4), and a workpiece carrier (2), the workpiece carrier (2) comprising:
a rotary frame (3) mounted on the base frame (1) so as to be rotatable about the drive axis (4),
workpiece holders (13) mounted on the rotary frame (3) so as to be rotatable about holding axes,
a driving part (22) with a holder mounted so as to be rotatable about the shaft (20),
a transmission part (26) operationally connected to the rotatably mounted workpiece holders (13), and
an intermediate gear attached to the rotatably mounted holder, the intermediate gear being operationally connected to the shaft (20) and the transmission part (26) in such a way that the transmission part (26) engages with the driving part (22) so as to be rotatable about an output point (29) that is spaced apart from the drive axis (4) by an eccentricity (E).

### Claim 2 (depends on 1)

The workpiece carrier device according to claim 1, wherein, for the purpose of rotating the workpiece holders (13) with respect to the rotary frame (3), the transmission part (26) further engages with at least two of the workpiece holders (13) so as to be rotatable about a driving point that is spaced apart from the holder axis by the same eccentricity (E).
