一、概述FG·4×22高方平筛是一种自衡式的回转筛,依靠一个围绕筛体中心旋转的偏置重量(以下简称甩势)使筛体作平面圆运动。我厂在试制这种筛子的过程中发现筛体回转不圆度达3～5毫米。屡经调整,见解纷云。现将运动分析结果论述如下。二、筛箱质心的运动方程 I. Overview FG · 4 × 22 high side flat screen is a self-balancing rotary sieve, relying on a sieve around the center of rotation of the bias weight (hereinafter referred to as throwing) so that sieve body for circular motion. I plant in the process of trial production of this sieve sieve body found that roundness of 3 to 5 mm. Repeatedly adjusted, divergent views. Exercise analysis results are discussed below. Second, sieve box centroid equation of motion
