Device for determining the torque and/or rotational angle between a first shaft and a second shaft

A device (1) for determining the torque and/or the rotary angle between a first shaft (10) and a second shaft (20), which are coupled via a gear mechanism (30) to rotate relative to one another about an axis of rotation (A),

• wherein the first shaft (10) has a first end region (10a), a second end region (10b), and a first direction vector (R1) pointing parallel to the axis of rotation (A) from the first end region (10a) to the second end region (10b),
• and wherein the second shaft (20) has a first end region (20a), a second end region (20b), and a second direction vector (R2) pointing parallel to the axis of rotation (A) from the first end region (20a) to the second end region (20b),
• characterized in that:
• the first shaft (10) is designed as a hollow shaft and the second shaft (20) is arranged coaxially in the first shaft (10) in such a way that the first direction vector (R1) and the second direction vector (R2) have the same orientation;
• the first end region (10a) of the first shaft (10) has a first measurement standard (11) and the first end region (20a) of the second shaft (20) has a second measurement standard (21), the first measurement standard (11) being scanned by a first sensor (41) and the second measurement standard (21) by a second sensor (42),
• wherein the first and second sensors (41, 42) are arranged frontally in front of the first end regions (10a, 20a) of the two shafts (10, 20).
