Abstract

An optical measurement system comprises a first housing body and a second housing body which can be rotated relative to the first housing body about a second axis of rotation, wherein the second housing body contains a measurement telescope, an inner roller bearing support fixed to the second housing body and protruding into the first housing body; an outer roller bearing support fixed to the first housing body; a drive disc fixed to the inner roller bearing support; wherein a motor having a motor shaft is attached to the first housing body in such a way that the motor shaft or a wheel fixed to the motor shaft is positioned on the drive disc and is pressed against said disc by a spring force orientated transversely to the second axis of rotation, and wherein the motor shaft or the wheel is coupled to the drive disc in a frictional fit.
