Measuring machine provided with an improved transmission system

摘要

A measuring machine comprising at least one member mobile along an axis, a motor, a transmission system driven by the motor for displacing the mobile member along the axis, and a control system for controlling the motor, wherein a flexible coupling is set between said transmission system, and the mobile member is configured so as to filter the vibrations transmitted by the transmission system to the mobile member in the direction of the axis and to decouple the mobile member from the transmission system in a direction transverse to the axis.

1. A measuring machine comprising:
at least one member mobile along an axis; a motor; a transmission system co-operating with the motor for displacing the mobile member along said axis; and a control system for controlling said motor, wherein said transmission system comprises at least one flexible coupling configured so as to filter the vibrations generated by at least one of said motor and transmission system and transmitted to the mobile member in the direction of said axis and to minimize the forces acting on said mobile member in a direction transverse to said axis, the at least one flexible coupling comprising at least one resilient member deformable in a direction parallel to said axis, and said control system configured so as to control the position of said mobile member to minimize the position errors of the mobile member along said axis resulting from the deformations of said at least one resilient member.
