Embodiment Construction

[0017] The present invention will be further described below in conjunction with the accompanying drawings and embodiments.

[0018] As we all know, there are the following four parameters to be measured for the offset of the two shaft centers of a set of counter wheels. The up and down offset a1 of the center of the two axes, and the left and right offset a2. The upper and lower openings b1, b3 of both ends, and the left and right openings b2, b4.

[0019] In order to detect the above-mentioned offset, it is necessary to install a first displacement sensor for measuring the circumferential offset and a second displacement sensor for measuring the displacement of the end face opening on the above-mentioned set of counter wheels. Fix the first displacement sensor A perpendicular to the axial direction on one wheel of the generator pair for measuring the circumferential offset of the other wheel, and fix the second displacement sensor A parallel to the axial direction on one of...

Abstract

The invention discloses an alignment instrument measurement and adjustment method for a generator coupling shaft system. The method is characterized in that the method comprises the following steps: 1, fixing a first displacement sensor on one of coupled wheels of a generator in a direction vertical to the axis to measure the circumference offset amounts of the other one of the coupled wheels, and fixing a second displacement sensor on the one of the coupled wheels of the generator in a direction parallel to the axis to measure the transverse plane opening displacements of the other one of the wheels; 2, measuring the circumference offset amounts and the end transverse plane opening displacements, calculating to obtain a horizontal offset amount, a vertical offset amount, an upper transverse plane opening amount, a lower transverse plane opening amount, a left transverse plane opening amount and a right transverse plane opening amount; and 3, calculating according to the horizontal offset amount, the vertical offset amount, and the upper transverse plane opening amount, the lower transverse plane opening amount, the left transverse plane opening amount and the right transverse plane opening amount to obtain pad adjustment amounts, and adjusting pads according to the pad adjustment amounts. The method has the advantages of fastness and convenience in the whole alignment process, and high precision.

Description

technical field [0001] The invention relates to the field of installation of generator sets, in particular to a method for measuring and adjusting a centering instrument used for a generator alignment wheel shaft system. Background technique [0002] In the installation of generator sets, the quality of the shafting installation is one of the key factors to ensure the safe operation of the unit. If the shafting installation is unreasonable, it will lead to uneven load distribution of each bearing. According to the static and load operating conditions of the unit, it is the key to the installation of the shafting system to distribute the load of each bearing reasonably. Therefore, during the installation and maintenance of the shafting system, the alignment of the shafting system is particularly critical. In the prior art, a large amount of manual calculations are performed first to determine an adjustment plan, and then trial adjustments and measurements are made again and a...
