Embodiment Construction

[0045] A balance plate with a structure: the shape of the main plate is cylindrical, and there is a frustum-shaped opening hole with the large end at the bottom in the main plate, and there is a cylindrical boss around the through hole on the axis; the shape of the attached plate is circular. The frustum shape is located in the frustum-shaped opening hole of the main disc body, and the opening hole on it is matched with the cylindrical boss in the main disc body, and the small end face of the attached disc body is opposite to the frustum-shaped hole bottom of the main disc body ;The inner surface of the frustum-shaped opening hole of the main disk body and the frustum-shaped outer surface of the attached disk body form an annular groove with a trapezoidal radial cross-section, and there are two balance weights in the groove; there are 0-360 on the surface of the attached disk body. ° scale.

Abstract

The present invention relates to dynamic balance mechanism in mechanical rotary rotor and its correction method. The balance plate includes main plate with annular slot, subsidiary plate connected to the main plate, and balance blocks installed inside the slot. Each of the plates has scales and each balance block has scale line on its surface. The digital correction method includes installing the balance plate, inputting initial data, measuring unbalance amount and phase angle, calculating and displaying data for the balance blocks to be shifted, shifting and fixing the balance blocks and observing correction effect. The present invention has short correction time, high precision and being simple and practical.

Description

Technical field: [0001] The invention relates to a balance mechanism and a correction method on a mechanical rotor. technical background: [0002] In order to ensure the working quality of high-speed rotating machinery and the safety of equipment, it must be dynamically balanced. At present, there are some computer on-site dynamic balancer products on the market, which can measure the size and direction of the unbalance of rotating parts in a short time. But after completing this step, the user also needs to restore the rotating part to the predetermined precise balance state. This operation is called "calibration". At present, there are several methods of correction, such as "weighting method", "removing weight method" and "computer automatic balancer method". It is noted that for high-speed rotating parts such as the grinding wheel of the grinding machine and the knife roller of the leather leveling machine, the grinding wheel or the knife roller is constantly worn durin...
