Analysis of Static Transmission Error of Screw Compressor Rotors by a Rigid Model.
TRANSACTIONS OF THE JAPAN SOCIETY OF MECHANICAL ENGINEERS Series C, 1991 A numerical method of calculating the static transmission error of screw compressor rotors is presented. Factors such as profile errors, lead errors, bearing position errors, and misalignment of the rotors with respect to the rotational shafts are considered in the calculation. All compressor parts are assumed to be rigid.

Dynamic Torsional Stiffness of Reducers and Its Testing Method
Applied Sciences, 2023 The torsional stiffness of the reducer is commonly assumed to be static and tested using the hysteresis curve method. However, practical engineering experience shows that the torsional stiffness is dynamic rather than static, and the hysteresis curve ...

Static transmission error measurement of various gear-shaft systems by finite element analysis
Journal of Measurements in Engineering, 2023 Transmission error (TE) is a significant parameter related to gears vibration widely investigated by many authors using different approaches. However, in previous studies, spur and helical gears were mainly examined. There is a lack of studies addressed to double helical and herringbone gears and a comparison among several types of gearing with ...
