A Venus–Earth–Jupiter spin–orbit coupling model is constructed from a combination of the Venus– Earth–Jupiter tidal-torquing model and the gear effect. The new model produces net tangen-tial torques that act upon the outer convective layers of the Sun with periodicities that match many of the long-term cycles that are found in the 10Be and 14C proxy records of solar activity…
