Background. Planetary cycloid gearings are increasingly used in various fields of machine engineering. If all contact surfaces of gearing are made with high hardness, its load capacity is limited by strength of satellites bearings and W-mechanism. To calculate W-mechanism it is necessary to know forces that load its elements. Existing method of static calculation does not allow to take into account actual accuracy of manufacturing W-mechanism. Purpose of work is improving accuracy of force calculations of W-mechanism taking into account manufacturing errors of its elements.
Materials and methods. Researches are based on basic provisions of mechanical systems statics. MathCad package is used in computer modeling.
Results. Continuum and discrete models of force interaction of W-mechanism elements of Planetary cycloid gearing are developed. Regularities of force interaction of satellites and pins of output shaft are revealed.
Conclusion. Resulting expressions constitute mathematical model that can be used to study statics of W-mechanism. Results of force interaction in W-mechanism, taking into account and excluding manufacturing errors, may differ significantly. Apply W-mechanisms with small number of pins is impractical.
