Measuring Device of Center of Weight and Unbalanced Moment of Rotating Body and Measuring Method using that

摘要

In recent years, precision mechanical components are miniaturized by outward processing speed can be accelerated. Accordingly, precision machine parts full time (eg read and write information on the hard disk actuator) is equipped with a hydrostatic machine products, the dynamic characteristics has become increasingly important. Receive a lot of the rotating body is affected by the unbalanced mass, etc. When operating about an axis of rotation, the unbalanced mass of the rotating body is a large effect on mechanical properties as well as performance as a part of the data read / write speed of the processing and control system of the entire product have a. Therefore, it is necessary compact, device capable of measuring the center of gravity and the unbalanced mass of the rotating parts are precision actuators such as a hard disk. ; The present invention is small, the weight of the rotor center and precisely measure the unbalance moment relates to a device that can be. A device to find the center of gravity of the rotating body by using the three force sensors. Three power adapter binary sensors and measurement platform, the rotor is placed throughout on the three force sensors are designed to be mounted on the platform, the measured values of the force sensor consists of a central processing unit to process this value. ; measured after zeroing Place the platform on top of the adapter is equipped with three power sensor is mounted to the rotor to be measured to the adapter. Counterclockwise, 60 is a first rotation interval measured by the total error of a calibration fixture, and once the center of gravity and the apparatus to obtain the unbalanced moments of the rotating shaft. ; The present invention is a three force sensors includes the measurement method of compensating for geometrical errors of the equipment and how to obtain the center of gravity of the rotating body, the rotating jig to load (measuring platform and measurement adapters) with.
