Embodiment

By reference to the accompanying drawings the specific embodiment of the present invention is described further.

A gear 2 is contained on input shaft 1, a gear 2 and No. two gears 5 engage, No. two gears 5 and No. three gear 3 duplexs are contained on an axle 4, No. three gears 3 and No. four gears 7 engage, No. four gears 7 and No. five gears 8 are contained on No. two axles 6, and No. five gears 8 and No. six gears 9 engage, and No. six gears 9, No. seven gears 22 and ten No. two gear 21 3 multi packs are on No. three axles 20, No. seven gears 22 and No. eight gears 17 engage, and No. eight gears 17 and No. nine gears 18 are contained on No. four axles 19; No. nine gears 18 and No. ten gears 14 engage, and No. ten gears 14 and ride on Bus No. 11 gear 16 are contained on output shaft 15.

Input shaft 1, axle 4, No. two axles 6 are all positioned at velocity-reducing chamber 11, and No. three axles 20, No. four axles 19, output shaft 15 are positioned at commutation chamber 13.The two ends of every root axle are all provided with bearing.

, in velocity-reducing chamber 11, power is inputted by input shaft, by a No. two gear pairs engagement, power is passed on an axle, then by No. three No. four gear pairs engagements, passed to by power on No. two axles, passing on No. three axles by No. five No. six gear pairs by power, so far power is imported in commutation chamber by velocity-reducing chamber.

In commutation chamber, No. seven gears 22 and ten No. two gears 21 are incomplete tooth, and install according to certain phase relationship, when No. seven gears 22 have toothed portion and No. eight gears 17 to be formed effectively to engage time, the toothless part of ten No. two gears 21 is relative with ride on Bus No. 11 gear 16, forms invalid engagement; When ten No. two gears 21 have toothed portion and ride on Bus No. 11 gear 16 to be formed effectively to engage time, the toothless part of No. seven gears 22 is relative with No. eight gears 17, forms invalid engagement.Such process alternately occurs, so just achieves the motion of same input shaft rotating Vortex and is converted to the motion of same output shaft different direction continuous rotation.

When No. seven gears 22 and No. eight gears 17 are formed and effectively engage, output shaft low speed and reverse, realizes cut cutter lifting process; When ten No. two gears 21 and ride on Bus No. 11 gear 16 are formed and effectively engage, output shaft rotates forward at a high speed, realizes forward cutting course.

For solving the lubrication problem of each gear and bearing, the present invention carries out the circulatory system of pressure lubrication to gear and bearing.Casing outwardalso be provided with motor 28, the output shaft of motor 28 connects oil pump 27, oil pump 27 inlet port is communicated with box house by fuel sucking pipe 26, oil pump 27 oil outlet connects a point oil clot 25, oil clot 25 is divided to connect the oil pipe 24 of some roads parallel connection, each oil pipe 24 outlet end connects oil nozzle 23, and each oil nozzle is arranged at each bearing and gears meshing vice division chief.Motor 28 drives pump 27 to rotate, by fuel sucking pipe 26 oil suction from casing 12, be sucked up the oil come and form multi-channel parallel oil circuit by a point oil clot 25, be assigned on oil nozzle 23 by relevant 24 again, in all bearings that gear oil sprays by oil nozzle 23 and engaging tooth wheel set, when guaranteeing that gear-box works, all bearings and gear all can obtain good effective lubrication.
