Method for improving pivoting of mobile assembly for e.g. meter, involves adjusting value of resultant unbalance moment of mobile in determined tolerance with respect to target value of resultant unbalance moment

摘要

#CMT# #/CMT# The method involves performing static balance of a mobile (1) to bring center of gravity of the mobile on an axis (D), and determining target value of resultant unbalance moment of the mobile about the axis. Rotation speed of the mobile is fixed at maximum angular speed calculated for a mobile assembly (40) during pivoting/oscillation with a return and/or electrostatic repulsion unit. The mobile is rotated at a preset speed around the axis to measure the moment relative to the axis. The value of unbalance moment is adjusted in determined tolerance relative to the target value. #CMT# : #/CMT# Independent claims are also included for the following: (1) a mobile assembly for a scientific instrument or chronometer (2) a mobile assembly. #CMT#USE : #/CMT# Method for improving pivoting of a mobile assembly for a scientific instrument e.g. meter and precision device, or chronometer. #CMT#ADVANTAGE : #/CMT# The method enables reducing friction in guides of rotating components e.g. precision components, and improving accuracy of operation of the mechanisms to improve quality of dynamic balance. The method enables increasing rotation speed and/or frequency of oscillation of components of the mobile assembly. The method enables reducing forces on pivots, facilitating lubrication, prolonging service life of mechanisms, and improving stability of operation of the mobile assembly. #CMT#DESCRIPTION OF DRAWINGS : #/CMT# The drawing shows a schematic longitudinal sectional view of a mobile assembly.
