Housings are key components which support transmission assembly. In many applications, housings are assumed to be perfectly rigid and are therefore neglected in the analysis. However, this simplification can lead to inaccurate results, particularly for lightweight or special-design housings. Different load cases defined in the load spectrum can significantly alter the magnitude and directio…

Static peak-to-peak transmission error (PPTE) is an advanced and efficient criterion for designing low-vibration gear sets, more accurate than rules of thumb and less complex than full dynamic analysis.
