浅谈影响电子皮带秤称重精度的几个因素

A brief discussion on several factors affecting the weighing accuracy of electronic belt scale

电子皮带秤机械部分对称重精度的影响占据着极其重要的地位,因为它对称重精度的影响占75%以上。称重传感器一侧为力点B,称重托辊为重点A (可能有A1、A2…等多个点,可以把它们合并分析),秤体定位点为支点O,另:秤体有绕该点转动的趋势,支点O有多种,有十字簧片,X字簧片,橡胶耳轴,刀子刀承,弹性圆环,轴承等,根据力点、支点、重点在杠杆上的相互位置不同,该类属于第二类杠杆,即重点的位置于支点和力点之间。

The influence of the mechanical part of electronic belt scale on weighing accuracy occupies an extremely important position, because its influence on weighing accuracy accounts for more than 75%. The side of the weighing sensor is Point B, the heavy supporting roller is the key Point A(there may be A1, A2, etc., which can be combined for analysis), the setting point of the weighing body is the fulcrum O, in addition, there are many kinds of fulcrum O, such as cross reeds, X-type reeds, rubber trunnion, knife bearing, elastic ring, and bearing etc. According to the different positions of force points, fulcrum and emphasis on the lever, this type of lever belongs to the second type, that is, the key position is between the fulcrum and the force point.
