Embodiment Construction

[0019] Such as figure 1 As shown, first pull out a steel wire as the measurement reference line (central line of the unit), and the distance between the rotation axis and the reference line is 40cm. A steel ring is placed on the rotating shaft again, hoops the rotating shaft, and a length of 100 cm channel steel is welded outside the steel ring, as a swing rod, and a micrometer is fixed on the top end of the rod. Connect the micrometer and the reference line into a circuit loop, record the reading of the micrometer at a critical contact point on the reference line, turn the steel ring, and read the reading of another contact critical point of the micrometer on the reference line. Fine-tune the position of the rotating shaft until the difference between the two micrometer readings is within the allowable range. Then loosen the steel ring outside the rotating shaft, turn the rotating shaft 90 degrees, re-tighten the steel ring, and repeat the above operation steps to ensure tha...

Abstract

The invention belongs to the technical field of machinery, in particular to a method for accurately controlling installation levelness and verticality of a large-size mechanical rotating shaft. The method amplifies errors by means of geometry, photoelectricity, and the like so as to more acutely control the levelness of the installation the rotating shaft and the verticality of the rotating shaftand a unit central line. Specifically, the method comprises the following steps of: firstly, pulling out a reference steel wire line; mounting a steel ring and a swinging rod fixedly connected with the steel ring on the rotating shaft; mounting a micrometer at one side of the top end of the swinging rod; measuring and controlling the reading difference of the micrometer at two contract critical points on the reference line; and finely adjusting the position of the rotating shaft until the accuracy requirement is satisfied. The method has simple operation and can accurately control the levelness and the verticality of the installation of the rotating shaft.

Description

technical field [0001] The invention belongs to the technical field of machinery, and in particular relates to a method for controlling the installation accuracy of rotating shafts of rotating machines in metallurgy or other industries. Background technique [0002] The installation accuracy of the roll (rotating shaft) in the metallurgical industry is very high, and its horizontal accuracy is generally required to reach 0.01mm / lm, and the perpendicularity to the production center line of the unit is also basically required to be at the level of 0.01mm / m. but. At present, the conventional installation method puts the spirit level on the surface of the roll to control the levelness of the roll, and there are two major defects. One is that there is an error in the surface processing of the roll (itself is uneven or there may be a taper), which is not enough to be used as a reference plane. The other is that What the installation requires is to find out the center axis of rota...
