Description
Technical Field
The invention relates to the field of measuring tools for couplers of factory equipment, in particular to an alignment device.
Background
Alignment of the coupling is also called alignment, for example: after the pump and the motor are installed, the last work is to make the pump and the motor concentric, that is, to make the axes of the pump and the prime mover on the same straight line, so that the pump and the prime mover do not vibrate during operation. The coupling is a part used for connecting a driving shaft and a driven shaft in different structures and enabling the driving shaft and the driven shaft to rotate together to transmit torque. In the alignment process, a driving shaft is a reference shaft, and a driven shaft is a shaft to be measured. When the coupler is installed, accurate alignment and centering must be carried out to ensure that the rotation centers of two shafts connected with the coupler are concentric, otherwise the vibration value of rotating equipment exceeds the standard; if the vibration value is too large, great stress can be generated on the coupling, the normal work of the shaft, the bearing and other parts on the shaft can be seriously affected, and even the whole machine and the foundation can be vibrated or damaged, so that the normal operation of the transmission equipment can be seriously threatened. Especially for equipment running at high speed, the data requirement for the alignment of the coupling is extremely strict. The coupler is used for measuring the radial deviation and the axial deviation of the shaft to be measured relative to the reference shaft, and calculating and correcting are carried out based on deviation numerical values. In the use process of the existing coupler alignment technology, the double-meter alignment is most widely used. However, in actual work, the center card and the magnetic gauge stand are often restricted by factors such as the structural form and the spatial position of the coupler, the size of the coupler and the like, two dial indicators cannot be installed at the same time by the center card and the magnetic gauge stand, and even the center card and the magnetic gauge stand cannot rotate along the axis of the coupler, so that the dial indicators cannot be directly used for alignment, and the alignment rate and accuracy of the coupler are directly influenced.
