ABSTRACT:
A rotary encoder is clamped coaxially with its pickup shaft (14) on a drive shaft (12) which is to be measured. Two collet chucks are provided for this purpose. The one collet chuck is constructed as a clamping sleeve, which penetrates the pickup shaft (14) axially and has clamping jaws (34) on its free end. The other collet chuck is constructed as a clamping ring, which engages the pickup shaft (14) with clamping jaws (38). The two collet chucks are clamped axially against each other and against the pickup shaft (14) by a force element (40).
