The two output shafts are mainly adjusted in the following ways: phase matching is a method for ensuring the phase requirements of two output shafts through processing; the transition gear is pressed and adjusted, namely the transition gear and the transmission shaft are in interference fit, and an oil groove is designed on a joint surface to expand the inner diameter of the transition gear by pumping pressure oil so as to realize free rotation adjustment of the transition gear and the transmission shaft.
The invention adopts the rectangular arrangement of gears, and realizes synchronous equidirectional rotation of the long output shaft and the short output shaft through transmission of multiple transition shafts. Through the reasonable setting of the number of the gear teeth, the adjustment of the phases of the two output shafts is realized through the transformation of the mutually meshed teeth between the gears, and the use requirement is met.
