Description
Technical field
The present invention relates to mechanical power transmission technical field, more particularly to a kind of double dynamical synthesizer.
Background technology
In many power-driven systems simultaneously, it is desirable to have two mechanical input shafts are acted on or complementation, and system is common
With an output shaft.Such as driven by power and the engine driving compensation device of automobile, the motor driving of electric assisted bicycle and
Foot drive device, using complementary drive system of wind-powered machine energy and motor mechanical energy etc., these are referred to as double
Dynamical system.Existing hybrid power system, has generally comprised two power input shafts and speed change gear and power output shaft, existing
The attachment structure for having technology is to be connected two power input shafts with the speed change gear by clutch respectively, by controlling system
System clutch and the connection for switching two input shafts and speed change gear.And operated simultaneously when there are two input shafts, and rotating speed is not
Then it is difficult that control makes two power complementary and effectively utilized, more during the situation that synchronous or each power input shaft rotating speed changes at random
It is difficult on the mechanical energy random synthesis of two input shafts to power output shaft.Because from the point of view of machine driving, two are moved
When power axle acts on same output shaft simultaneously, the low side of rotating speed can turn into the resistance of the high side of rotating speed, not only can not be by two
Individual power superposition is used, but also system may be caused harm, and in order to avoid this harm, ratchet is usually used on the driving shaft
Structure, but ratchet structure can not make two motive torque synthesis.How by two random variable machine power axle speeds or
Torque synthesis output, does not produce influence mutually again between them, does not influence transmission efficiency, and do not produce reaction to output shaft
Influence, still without more satisfactory technical scheme.
The content of the invention
There is provided a kind of new double dynamical synthesizer for above-mentioned the deficiencies in the prior art by the present invention.
The technical scheme that the present invention solves above-mentioned technical problem is as follows：A kind of double dynamical synthesizer, including housing, its feature

Reaction force can be balanced mutually, so as to improve transmission efficiency；Select proper in actuation types, in the case of reasonable structural arrangement,
Its transmission efficiency can reach 96%-98%.
3. gearratio is larger, it is possible to achieve the synthesis and decomposition of motion, as long as the class of appropriate selection Planetary Gear Transmission
Type and with tooth scheme, just can obtain very big gearratio with a few gear, in the case where there is very big gearratio,
Still can be compact with holding structure, small volume, the small advantage of quality；Moreover, it can also realize the synthesis of motion and decompose and real
The compound movement of existing various speed changes.
4. the present invention operates steadily, the ability of shock resistance and vibration is strong；Due to using several structure identical planetary gears,
Uniformly it is distributed in around sun gear, so as to so that sun gear and planetary inertia force are mutually balanced；Meanwhile, also make
The number of teeth for participating in engagement increases, thus it is planetary operate steadily, the ability of shock resistance and vibration is strong, works relatively reliable.
On the basis of above-mentioned technical proposal, the present invention can also do following improvement.
Further, first bearing of input shaft and the second bearing of input shaft are arranged in pairs, wherein per centering at least one
Individual is unilateral bearing.
Beneficial effect using above-mentioned further scheme is can to avoid working as in two input shafts wherein using unilateral bearing
One when running out of steam, the axle reverse transfer that will not output power to the outer power device.It it also avoid on outer power device
Separately set band-type brake or one-way transmission mechanism.
Further, the housing is included in support floor, first bearing of input shaft and the second bearing of input shaft respectively
There is a bearing on the support floor, the gear ring bearing is also on the support floor.
Beneficial effect using above-mentioned further scheme is, sets support floor and by one end of the first and second input shafts
It is supported on the support floor, it is shorter located at wheelbase on housing than by each spring bearing, so that transmission performance is ensure that, big
When torque is synthesized, each axle can have preferably rigidity.Because support floor effect also causes more compact structure of the present invention, it is not necessary to
Because axle is oversize and the overstriking diameter of axle.
Further, the planet carrier bearing is fixed on the housing by planet carrier shaft bearing sleeve.
Beneficial effect using above-mentioned further scheme is using planet carrier shaft bearing sleeve planet carrier support can be made more steady
Gu, it is easy to bear larger driving torque.
Further, the outer end of the gear ring is additionally provided with thrust bearing, and the thrust bearing is fixed on by thrust axis bearing sleeve
On housing.
Beneficial effect using above-mentioned further scheme is, due to the power coupling between gear ring and planet carrier, can be dynamic
Outside axial thrust is produced on power output shaft, therefore uses thrust bearing can guarantee that axle is not altered in long-term motion.
Further, the gear ring and planet carrier are reducing cylinder barrel shaped, and the outer diameter of the gear ring and planet carrier is small
In inner diameter.
Beneficial effect using above-mentioned further scheme is that the coupling of planetary gear and gear ring had both been can guarantee that using reducing gear ring
Space is closed, the fixed support to gear ring and planet carrier is can guarantee that again, installing space is reduced.
