Embodiment;
The present invention will be further described below in conjunction with accompanying drawing: as shown in Figure 1, 2, a kind of novel two-way gearing down method of drop that has is characterized in that concrete drive method is: torque T 1 realizes once increasing through bevel gear mechanism and turns round and realize realizing once increasing turning round finally through stud wheel mechanism again to both sides output and realizing by planetary mechanism that last increasing turned round and obtain T2 and T3 of moment of torsion equilibrium through box of tricks; Drive bevel gear 2-1 and driven wheel of differential 2-2 form a pair of gear pair as shown in Figure 2, make power turn 80 ° of-90 ° of transmission by Vertical direction; Driven wheel of differential 2-2 is connected with bolt with differential mechanism 2-3, is connected with left half axle 2-4 on the differential mechanism 2-3 and links to each other with two side wheel limits with right axle shaft 2-5; Right axle shaft 2-5 is delivered to the active post tooth 3-1 on right side, and the drop value that active post tooth 3-1 is connected with driven post tooth 3-2 equals the mounting distance of this coupled columns tooth; Power is delivered to the sun gear 3-4 of NGW formula planetary mechanism 1-1 through wheel limit semiaxis 3-3 by driven post tooth 3-2; Be delivered to planet wheel 3-5 by sun gear 3-4; Planet wheel 3-5 and ring gear 3-6 carry out engagement driving; Ring gear 3-6 and mechanism's housing are fixed together, and planet wheel 3-5 integral body around the rotational of ring gear 3-6, drives planetary carrier and planet pin 3-7 around ring gear 3-6 rotational under the driving of engaging force.
Bevel gear comprises: straight line bevel gear, spiral bevel gear, hypoid bevel wheel; Stud wheel comprises straight toothed spur gear (comprising displacement and non-displacement), helical gear (comprising displacement and non-displacement), herringbone tooth cylindrical gears (comprising displacement and non-displacement).
The commutation of power as shown in Figure 3 increases to be turned round, and power forms a pair of gear pair by drive bevel gear 2-1 input with driven wheel of differential 2-2, can obtain speed ratio i01 at this place, and realization one-level reduction of speed increases to be turned round; Can make power turn 90 ° of transmission by this to bevel gear by Vertical direction.This to gear can also other angles of conversion as 80 ° or 87 °.
Next power passes to differential mechanism 2-3 by driven wheel of differential, and differential mechanism 2-3 the effect here is to allow the variable speed transmission of two side wheel limit mechanisms.Power is gone up the left half axle 2-4 and the right axle shaft 2-5 that connect by differential mechanism 2-3 and is delivered to two side wheel limits.The rotating speed of left half axle 2-4 and right axle shaft 2-5 and moment of torsion all can be unequal.Therefore power is exported (and two-way output) through the effect of differential mechanism to both sides by drive bevel gear 2-1 input.
As shown in Figure 4, mechanism's drop is because left and right sides power transmission structure is identical, so describe as example with the right side structure.Power is through the shunting of the both sides of differential mechanism, and wherein a part of power is delivered to the active post tooth 1 on right side by right axle shaft 5, is delivered to driven post tooth 2 by active post tooth 1 again.Realized the drop of entire mechanism like this by a coupled columns tooth.The concrete numerical value of this drop equals the mounting distance of this coupled columns tooth.Can obtain speed ratio i02 on this coupled columns gear mechanism, realizing slows down to increase for the second time turns round.Final power output is the sun gear 3-4 that is delivered to NGW formula planetary mechanism by driven post tooth 3-2 through wheel limit semiaxis 3-3.Be that power is delivered to planet wheel 3-5 by sun gear 3-4; Planet wheel 3-5 and ring gear 3-6 carry out engagement driving; Because ring gear 3-6 and mechanism's housing are fixed together, thus planet wheel 3-5 integral body under the driving of engaging force around the rotational of this ring gear 3-6, planetary pinion 3-5 can drive planetary carrier and planet pin 3-7 around this ring gear 3-6 rotational like this
(the ring gear axis overlaps with the sun gear axis), the final moment of torsion and the output of rotating speed are exactly to realize final output by planetary carrier and planet pin 3-7.The final like this speed ratio i03 that obtains on the NGW planetary mechanism realizes it also being to slow down to increase for the last time to turn round for the third time.
All axial workpieces of the present invention all use spline to be connected with other parts.
Speed ratio i0 of the present invention is: i0=i01*i02*i03
Power is: T1=T2+T3
