Abstract

The invention relates to a hollow parallel harmonic reduction device and a driving method thereof. The harmonic reduction device comprises a hollow shaft, a harmonic reduction assembly and an output shaft, wherein the hollow shaft can rotate around the central axis thereof, and a first hollow hole is formed in the hollow shaft; the harmonic reduction assembly is arranged on the outer side wall of the hollow shaft and comprises a first harmonic reducer and a second harmonic reducer which are distributed in the axial direction of the hollow shaft; the output shaft is located in the first hollow hole and is connected with the harmonic reduction assembly to achieve power output of the harmonic reduction assembly; and the hollow shaft drives the first harmonic reducer and the second harmonic reducer to work synchronously, the first harmonic reducer and the second harmonic reducer transmit power to the output shaft, and the output shaft outputs the power. The harmonic reduction device can obtain higher rotary positioning precision and higher torsional rigidity, and is good in synchronism, compact in structure and good in stability.

Description

technical field [0001] The invention relates to the technical field of reducers, in particular to a hollow parallel harmonic reducer and a driving method thereof. Background technique [0002] The unique advantages of high load capacity, large transmission ratio, small size, stable transmission and high transmission precision make harmonic reducers widely used in electronics, aerospace, robotics and other industries. [0003] The existing harmonic reducer is arranged on the power output shaft of the driving source, and the power is transmitted through the harmonic reducer. However, when the load is too heavy, the torsional rigidity of the harmonic reducer is often not enough, and the rotation positioning accuracy is poor. Contents of the invention [0004] Therefore, the technical problem to be solved by the present invention is to overcome the technical defects of poor rotational positioning accuracy and insufficient torsional rigidity of the harmonic reducer in the prio...
