機(jī)械振動(dòng) — 在恒定（剛性）狀態(tài)下轉(zhuǎn)子的平衡質(zhì)量要求
Specification and verification of balance tolerances
平衡公差的技術(shù)說明和確認(rèn)
1 Scope
This part of ISO 1940 gives specifications for rotors in a constant (rigid) state. It specifies
a) balance tolerances;
b) the necessary number of correction planes; and
c) methods for verifying the residual unbalance.
1 范圍
ISO1940的本部分給出了在恒定（剛性）狀態(tài)下轉(zhuǎn)子的技術(shù)說明，其規(guī)定了
a) 平衡公差，
b) 所需校正平面的數(shù)量，
c) 校正剩余失衡的方法。
Recommendations are also given concerning the balance quality requirements for rotors in a constant (rigid) state, according to their machinery type and maximum service speed. These recommendations are based on worldwide experience.
根據(jù)機(jī)加工類型和最大運(yùn)行速度，給出了在恒定（剛性）狀態(tài)下，對(duì)轉(zhuǎn)子平衡質(zhì)量要求的建議，這些建議基于在世界范圍內(nèi)共有的經(jīng)驗(yàn)。
This part of ISO 1940 is also intended to facilitate the relationship between the manufacturer and user of rotating machines, by stating acceptance criteria for the verification of residual unbalances.
通過闡述剩余失衡確認(rèn)的確認(rèn)標(biāo)準(zhǔn)，ISO1940的此部分還促進(jìn)了制造商和旋轉(zhuǎn)設(shè)備用戶之間的聯(lián)系。
Detailed consideration of errors associated with balancing and verification of residual unbalance are given in ISO 1940-2.
與平衡和剩余失衡確認(rèn)相關(guān)的誤差細(xì)節(jié)分析見ISO1940-2。
This part of ISO 1940 does not cover rotors in a flexible state. The balance quality requirements for rotors in a flexible state are covered by ISO 11342.
ISO1940的此部分不包括彈性狀態(tài)下的轉(zhuǎn)子，彈性狀態(tài)下的轉(zhuǎn)子平衡質(zhì)量要求見ISO11342。
