Abstract
Aiming at real time rotation speed control of threshing drum and cleaning fan for combine harvester, a stepless speed regulation mechanism was developed. Test show that the adjustable range of fan was 600～1150 r/min, average adjustment speed was 9.2 r/s, the absolute error of stable speed was less than 0.72 r/min. The average speed response time was 1.33s, the overshoot was less than 8 r/s. The adjustable range of the drum was 700～1100 r/min and the average adjustment speed was 2.1 r/s. The absolute error of stable speed did not exceed 0.62 r/min, and the maximum relative deviation was 0.38%
