Oscillations due to manufacturing always occur in a gearbox. Typical manufacturing defects are pitch errors, profile deviations, concentricity and spacing errors.

Depending on the gearwheel pairing, these individual defects can intensify or become less intense depending on how the defects affect each other. The interplay of the individual defects is also responsible for the overall oscillation behavior.

Pitch error is a frequently occurring defect and is used as an example here. Depending on whether the pitch error is positive or negative, it is intensified or compensated by an existing load. The effects on the oscillation behavior depend very much on the rigidity of the gearwheel. If there is a pitch error, a shock occurs that can be measured effectively.

In addition to pitch errors, all form and dimensional gear errors lead to oscillations.

 

齿轮箱中总是会出现由于制造而引起的振荡。典型的生产缺陷是节距误差、轮廓偏差、同心度和间距误差。

根据齿轮配对的不同，这些单独的缺陷可能会加剧或减弱，这取决于缺陷如何相互影响。各个缺陷的相互作用也是造成整体振荡行为的原因。

节距误差是一个经常发生的缺陷，在这里作为一个例子。根据节距误差是正的还是负的，它由现有负载来增强或补偿。对振荡行为的影响在很大程度上取决于齿轮的刚度。如果存在节距误差，就会出现可以有效测量的冲击。

除了节距误差，所有形状和尺寸的齿轮误差都会导致振荡。
