杠杆式机械天平三刀吃离线调整的理论计算

The Theoretical Calculation on the Adjustment of Mechanical Beam-balance Three Edges of Knife Feed & off Line

在杠杆式机械天平调修中,三刀吃离线的调修难度很大。调整时,大多数人都是凭经验,调到什么位置合适,视具体的情况而定。当经验不足时,不知调整的量如何把握,往往会不断反复,甚至常把天平调修"坏"了。本文以TG328单杠杆式机械天平为例,介绍一种杠杆式机械天平三刀吃离线调修的计算公式和计算方法,相信你从此可以轻轻松松完成天平三刀吃离线的调修。

In the adjustment and repair of the mechanical beam-balance,it＇s very difficult to repair three edges of knife feed off line.During adjustment,most people are just depending on their own experiences,the adjusted appropriate position they thought is depends on the detailed situations. The lack of experiences often leads to inappropriate controlling of the amount of the adjustments,thus,a continuous repeatable adjustment will even lead to a broken result.This article takes the TG328 single mechanical beam-balance as an example,makes an introduction on the calculation formula and method to repair three edges of knife feed off line of the mechanical balance.
