Description

Coupling centering device for training

technical field

The invention relates to a shaft coupling centering device used for practical training, and belongs to the technical field of shaft coupling centering.

Background technique

The traditional training device for finding the center of the coupling focuses on the measuring tool, but does not focus on the adjustment tooling. According to the theoretically calculated opening value, eccentric value and the direction of the center deviation, the adjustment is carried out as follows: the four fulcrums representing the base of the motor side are arranged symmetrically on both sides. When adjusting the deviation of the coupling in the vertical direction, use Lift the four tentacles of the base with the crowbar to add (or subtract) the spacers. The thickness of the spacers added (or subtracted) by the two symmetrical fulcrums is equal. During the process of prying, the center of the coupling will be shifted; When adjusting the deviation of the coupling in the horizontal direction, the left and right and front and rear adjustments use copper rods to hit the antennae, and use the gap between the bolts and the holes on the four antennae to meet the adjustment needs. Using this method to adjust the center is rough and has low precision. It must be adjusted many times, which consumes a lot of labor and prolongs the time to find the center. In addition, the eccentric difference of the coupling center is prone to exceed the standard, and the quality standard for centering cannot be met.
