Causes of gear box vibration
All Gear Boxes are connected to other machines.
Therefore, it is heavily influenced by it. However, there are also problems
with the gear itself, for example, gear vibration occurs due to misalignment of
the pitch line, eccentricity, or inconsistency between tooth intervals.
Internal defects of the Gearbox itself and external defects affecting the
Gearbox are summarized as follows.

Gear frequency-5-기어의 진동원인들(외부결함, 내부결함)

기어박스는 변속을 하여 피동부에 동력을 전달하는 기계요소(벨트, 체인 등)중의 하나로서 다른 유사 요소와 가장 큰 특징은 강한 토오크를 전달할 수 있다는 것이다. 따라서 고속의 동력으로 저속의 강한 토오크를 필요로 하는 곳은 대부분 강한 부하를 받는 곳이다. 기어박스는 특히 시멘트의 견인 및 파쇠, 타이어의 파쇠 및 압출, 열차의 빈번한 동력전달 등에서 감속기로 활용된다. 반면에 가스생산의 고압 토출에 사용되는 기어박스는 증속기로서의 회전변경을 위해 사용되는 경우도 있다. 다시 한번 살펴보면 기어박스는 절대로 홀로 움직여서 활용될 수 있는 기계요소가 아닌 것을 확인할 수 있다. 그래서 진동이 발생한다.

Unlike temperature measurement, where you can select
only Celsius or Fahrenheit and press a button, you need to know a lot about
'vibration' before measuring. How to select units and how far is the frequency range? What
are the types of sensors and how to attach them? Also where? in which
direction? Everyone should know how to measure. As a metaphor, 'knowledge
is something that is easy for those who know it, unlike wisdom that is
difficult even if you know it.' If you know about the vibration, it is easy to
measure the selectivity of the instrument.
Distinct difference between vibrometer
(vibrometer and frequency analyzer FFT vibration analyzer)
Recent vibrometers that can perform simple spectrum
frequency analysis and trend storage are being sold at low prices, but in
general, vibrometers do not have as precise or diverse functions as FFT
(vibration frequency analyzer). Therefore, it is necessary to know the
practical optimal knowledge that can identify these differences, and refer to
the following.

(resonance), machine diagnosis, long term recording (DAQ), rotor dynamics,
front-end or hand held, for Labs and machine analysis |

Sensor selection |
-The magnet attached type is better than
the probe stick type because measurement stability and high frequency are
possible. -Sensitivity modifiable instrument (high sensitivity,
high impact measurement possible) -Sensitivity
modifiable instrument (high sensitivity, high impact measurement possible) |
-For low
frequency detection (using displacement sensor and DC sensor, or using
acceleration of 500mV/g or higher) -General
type acceleration sensor (100mV/g) -High
impact acceleration sensor (10mV/g) |

This data is very
realistic and it is the result confirmed in the actual domestic industrial
field, but it can be subjective and biased, so please refer to it.
