Description

Technical field [0001] The invention relates to the field of electromechanics, in particular to a new type of planetary reducer and reduction motor. Background technique [0002] Harmonic gear transmission includes three basic elements: wave generator, flexible wheel and rigid wheel. Among them, one of the three basic elements can be fixed arbitrarily, and one of the remaining two is active and the other is driven, which can realize deceleration or increase, and can also be transformed into two inputs and one output to form a differential transmission. If two sets of harmonic gear devices are combined to share a wave generator and a flexspline, two rigid wheels, flexsplines and wave generators with the same pitch diameter and different numbers of teeth form the new four elements, the flexspline As an intermediate transmission part, one of the remaining three components can be fixed at will, the remaining two, one is active and the other is driven, which can realize deceleration ...
