Calibration rotor and calibration method of a horizontal hard bearing dynamic balancing machine

Abstract

The present invention discloses a correlation rotor of a horizontal hard bearing dynamic balancer and a calibration method thereof. The correlation rotor comprises a mandrel, wherein the mandrel includes a left support segment configured to be held at the bearing bracket of the balancer, an interference fit segment configured to be in interference fit with the centre hole of a left end cover, a spacing segment with axial direction spacing, a clearance fit segment configured to be in clearance fit with the centre hole of a right end cover, a thread segment configured to fit for a lock nut and a right support segment from left to right; the end face between the left end cover and the right end cover is provided with a mounting ring, a spacing board is formed at the outer wall, the outer ring of the mounting ring is a conical surface, and a plurality of screwed holes matching a trial mass are formed in the vertical direction of the mounting ring. The calibration method comprises the following steps: selecting the trial mass, inputting the dimension parameters of the rotor to the balancer, balancing the correlation rotor, marking a zero, performing a calibration test and determining a calibration result. According to the invention, the real-time precision calibration of a horizontal hard bearing dynamic balancer for detection of the cylinder unbalance amount of composite materials may be realized, and the position accuracy error between calibrated points is small.

Description

technical field [0001] The invention belongs to a calibration rotor and a calibration method thereof, in particular to a calibration rotor of a horizontal hard-supported dynamic balancing machine and a calibration method thereof. Background technique [0002] The composite cylinder is a part of high-speed rotating machinery, and its initial imbalance will directly affect its radial vibration amplitude. This kind of cylinder is made of filament winding, whether the winding is uniform or not, and the shape and position error after machining will directly affect the imbalance of the cylinder, and then affect the performance of the whole machine after assembly. In order to accurately measure the initial unbalanced mass of the cylinder, a detection method for a horizontal hard-supported dynamic balancing machine was established. Since the dynamic balancing machine is not a measuring instrument, there is no relevant verification standard and method. Therefore, in order to realize...
