(c) >30g
(c)8+BPFO 与/或BPFI 谐波加1x RPM 边带表示电蚀严重，通常导致轴承滚道呈“搓衣

B、Gears 齿轮
1.Tooth Wear or Scoring (a)
2.5-
3.0g;Impacting pattern very repeatable but
麻将机维修
typically only 1/4 to 1/2 rev. in waveform
(a)Typically1x GMF but without1x RPM
可爱的动物教案harmonics
齿轮牙齿磨损或刮伤(b)3.0-5.0g,Impact pattern is more discernible and
repeatable, plus growth in waveform amplitude.
(b)Typically1x GMF is highest but2x GMF
and/or3x GMF may appear in higher Fmax
spectrum.
(c)>5g;Impact pattern very distinct and typically
extends beyond 1/2 rev. of worn gear.
(c)High1x GMF typically accompanied by
growth in amplitude of2x GMF and/or3x
GMF;also,1x RPM harmonics often appear
if tooth cracks propagate to the surface or
root. [?pr?p?ɡeit]
(a)2.5-3.0g;冲击模式具有重复性，在时间波形上
通常每1/4到1/2转
(a)通常 1 x GMF但是没有1 x RPM 谐波
(b)3.0-5.0g,冲击模式更易识别和重复，时间波形
上冲击幅值增加
(b)通常1x GMF最高，2x GMF和/或3x
GMF 也许出现在Fmax更大的频谱上(c)>5g;冲击模式非常清晰，通常扩展超出了磨损
齿轮的1/2转
(c)高1x GMF通常伴有2x GMF和/或3x
钟汉良电影GMF幅值增加;同样,如果齿轮开裂扩散到
表面或根部，会经常出现1 x RPM谐波。
2.Cracked or Broken Teeth Amplitudes are difficult to predict but waveform
shows1or2regions of puls often3-6g.TWF is
best indicator of this problem.
Lower Fmax 20x pinion RPM)
typically shows roughly3–6harmonics of1
x RPM.higher Fmax 2.25-
3.25x GMF)sometimes shows elevated1x
GMF.
a.Subsurface Tooth Cracks 幅值很难预示故障，但是时间波形上1到2各区域
经常有3-6g的冲击。TWF能最好说明此问题的存在
。
低Fmax频谱（比如20X小齿轮RPM）通常
答题显示1XRPM的3-6各谐波。高Fmax频
谱（比如2.25-3.25GMF）有时显示升高的
1XGMF
开裂或者损坏的齿轮
底部牙齿开裂
b.visible cracks or broken teeth Amplitudes again difficult to predict but TWF will also
show1or2regions of distinct[dis?ti?kt]puls often
>15 - 20g. Very apparent in TWF.
Lower Fmax spectrum typically shows many
角的多音字
1x RPM harmonics of the gear with the
problem.Higher Fmax spectrum sometimes
shows elevated 1 x GMF and harmonics.
可见开裂和牙齿损坏幅值仍然很难预示故障，但是TWF在1或2个区域有
明显的大于15-20g的冲击，在TWF很明显。
低Fmax频谱通常表现出许多故障齿轮的
1XRPM谐波。高Fmax频谱有时表现出升高
的1XGMF和谐波。
3.Gear Lubrication Problems ~3-4g;TWF amplitudes are typically low since impact
energy is concentrated in very high frequencies and
dissipates[?disipeit]rapidly from gears to
measurement locations.
Lube problems normally cau elevated1x
GMF.However,2x GMF will grow if lube
problems degrade allowing micro welding
(instantaneous[??nst?n?teinj?s]metal-metal
contact between tooth surfaces that can
cau peeling [?pi:li?] and flaking).
齿轮润滑问题~3-4g,TWF幅值通常低的，冲击能量集中在高频并
快速从齿轮到测量位置消散。润滑问题通常使1XGMF升高。然而，2XGMF会增长假如润滑问题降低了可接受的微小粘接（牙齿表面金属与金属瞬间接触导致覆盖层脱落）
4. Backlash Often>5-10g;High amplitudes in TWF are due to
impact between mating gear teeth.
Most always caus high2x GMF in
PeakVue spectra. Will often cau many
后冲通常大于5-10g，高幅值的TWF是由于齿轮啮合时
的冲击。sidebands around2x GMF,spaced at1x RPM(and also sometimes spaced at2x RPM).
在PeakVue频谱中大多数经常导致2XGMF
。也常导致许多2XGMF的边带，间隔
1XRPM（有时也有2XRPM）
C、Lube Problems
润滑问题
Friction[?frik??n] Induced Can Cau excessive[ik?siv]g levels>50g,but since
friction-induced faults generate high frequencies in
the range of10,000-15,000Hz,much of their signal
rapidly dissipates with distance to transducer and at
each interface.TWF is normally random with little or
no periodic events.
Friction-induced lubrication problems excite
a wide range of high frequencies,typically
ranging from just below5000Hz up to
frequencies exceeding[ik?si:d]15,000–
