Abstract: In order to get the specified motion output of noncircular gear composite mechanism, the impact of characterization factor of deformed elliptical gear upon the gear parameters design and mechanism motion principle is studied. Firstly, the effects that eccentricity, deforming ratio, crack initial angle and other parameters may have upon the mechanism output motion principle is discussed in detail based on the deduction of calculation formula of pitch line of deformed elliptical gear, velocity of execution component and its displacement. Secondly, according to the requirements for deformed elliptical gear pair with same parameters, the design method and principle for deforming elliptical gear pair is presented. Both theoretical research findings and experimental results show that the expected motion can be obtained by selecting and adjusting characterization factor of deformed elliptical geared linkage mechanism even with the deformed elliptical gear which is devised in accordance with the basic design conditions.
