Problems solved by technology

However, there are some problems with this method. Some equipment is limited by the space position, and it is impossible to set three dial gauges at the same time and make them rotate with the coupling; or the end surface of some couplings is rough, and the percentage cannot be set. table, so that the alignment of the concentricity of the coupling cannot be performed by the method of three table alignment

Embodiment Construction

[0057] When the dial indicator cannot be normally erected on the shaft coupling to realize 360° rotation synchronously with the shaft coupling, using the method of the present invention to correct the concentricity of the shaft coupling can fully meet the requirements of the specifications and technical documents.

[0058] The present invention will be described in more detail below with reference to the accompanying drawings.

[0059] (1) Measurement and calculation of radial misalignment

[0060] Figure 2a It is a schematic diagram of setting the radial measuring gauge 20 according to an embodiment of the present invention, and setting the radial measuring gauge 20 in the horizontal direction of the reference end of the coupling; Figure 2b show Figure 2a The middle radial measuring table 20 records the three positions of the readings, these three positions are respectively the measurement positions of the shaft coupling separated by 90°, and the position 21 is the reading...

Abstract

The invention relates to an aligning method of the concentricity of a coupling. The traditional method for aligning by using three gauges has the problems that: some equipment is limited by a space position and is not capable of being provided with three dial gauges and enabling the three dial gauges to rotate along with the coupling; or the end surface of the coupling is machined to be rough andis not capable of setting the dial gauges, and therefore the aligning of the concentricity of the coupling cannot be carried out by using the method for aligning through three gauges. According to the invention, the method comprises the following steps of: measuring and calculating the radial nonconcentricity of the coupling; and measuring and calculating the axial nonconcentricity of the coupling. The method provided by the invention has the advantages of concise principle, convenience for operation, simpleness in calculation and high accuracy, thereby being capable of being widely applied.

Description

technical field [0001] The invention relates to a method for correcting the concentricity of a coupling, in particular to a method for correcting the concentricity of a coupling using triangle similarity calculations. Background technique [0002] Couplings are an essential connecting device between shafts and shafts in running mechanical equipment. The purpose of alignment is to make the centerlines of the driving shaft and the driven shaft on the same straight line when the machine is working. The alignment accuracy of the concentricity of the coupling is related to whether the machine can run normally, and directly affects the quality of equipment operation, especially for high-speed machines. Therefore, the alignment of the concentricity of the coupling is one of the most important processes in the installation of the operating equipment. [0003] The traditional method of aligning the concentricity of the coupling is to install 3 dial gauges on the coupling through th...
