The disc at the left end of the output shaft 506 is fixed to the right side of the herringbone-tooth outer ring gear 501 through a screw II502, and the right end of the output shaft 506 is fixed to the case through an output shaft bearing 505. Therefore, the load balancing device with the fixed outer ring axis and the floating inner ring axis of the output gear is formed. The fixed herringbone-tooth outer gear ring 501 is meshed with the single-meshing herringbone-tooth outer gear 106 with three floating axes, and the floating herringbone-tooth inner gear ring 504 is meshed with the double-meshing herringbone-tooth outer gear 301 with three fixed axes.
The box body mainly comprises an annular main box body 601, a left box body end cover 602, a right box body end cover 603, a screw III604, a screw IV605, an outer ring input shaft transparent cover 606, a central input shaft transparent cover 607 and an output shaft transparent cover 608. The left box cover 602 and the right box cover 603 are fixed to the main box 601 through screws III604, the outer ring input shaft transparent cover 606 and the center input shaft transparent cover 607 are fixed to the left box cover 602 through screws IV605, and the output shaft transparent cover is fixed to the right box cover 603 through screws. The transparent covers at the two ends can not only allow the outer ring input shaft 102, the central input shaft 202 and the output shaft 506 to pass through the middle hole, but also observe the operation condition inside the seal.
The specific working process is as follows:
power is transmitted to the three single-meshing herringbone-tooth external gears 106 and the central multi-meshing herringbone-tooth external gear 206 through the three outer ring input shafts 102 and the central input shaft 202 respectively, the power is directly transmitted to the herringbone-tooth external gear ring 501 in the output device through the three single-meshing herringbone-tooth external gears 106 on the outer rings to form a transmission route I, the power is transmitted to the double-meshing herringbone-tooth external gears 301 of the three fixed shafts through the multi-meshing herringbone-tooth external gear 206 with the floating central axis, and then the power is transmitted to the herringbone-tooth internal gear ring 504 in the output device through the gears to form a transmission route II. The transmission ratio of the transmission line I is the same as that of the transmission line II, and the speed synchronization of the inner gear ring and the outer gear ring of the double-meshing floating herringbone gear is realized. The axes of the gears are alternately floating and fixed from input to output, so that the problems of uneven load, movement blocking and the like caused by errors such as processing, installation and the like are solved, the automatic adjustment of the radial position and the stable transmission of the movement are realized.
