在普通杠杆秤上,对刀口工作刃相对位置的要求有详细规定,可概括为:每一杠杆上各刀口的工作刃应处于同一平面上并互相平行,而且要垂直于杠杆摆动平面。其允许偏差在企业标准中已有规定。随着以杠杆机构互换性为基础的分单元调整法的采用,对这些要求有详细讨论的必要。关于杠杆上刀口的工作刃应在同一平面上的要求,是众所周知的。在衡器理论中,刀口工作刃的
In ordinary lever scales, the requirements for the relative position of the blade at the blade edge are specified in detail. It can be summarized as follows: the blade edges on each lever should be in the same plane and parallel to each other, and should be perpendicular to the lever swing plane. The allowable deviation has been stipulated in the enterprise standard. With the introduction of the subunit adjustment method based on the interchangeability of leveraged institutions, there is a need for a detailed discussion of these requirements. It is well-known that the working edge of the upper blade edge should be on the same plane. In the weighing theory, the edge of the blade
