Abstract
The invention discloses a variable torque planet crank shaft. The variable torque planet crank shaft comprises an inner gear ring, a dual planet gear and an output sun gear on a crank shaft box, wherein the dual planet gear is installed on the outer side of an output end journal of the crank shaft, and the dual planet gear is meshed with the inner gear ring and the inner portion and the outer portion of the output sun gear. The output sun gear serves as an output wheel (shaft) of the power terminal of the crank shaft. According to the variable torque planet crank shaft, on the basis of the characteristics of the planet gear and the mechanics principle, the planet gear is adopted to serve as a leading component to transmit torque, through the arrangement of the dual planet gear and the adjustment of angular speed and linear speed, the rotate speed of the crank shaft is increased, the torque is increased, and the output efficiency is obviously improved. The variable torque planet crank shaft is novel and unique in form and simple and reasonable in structure, irreplaceability is achieved, the transmission performance is stable and reliable, the application is wide, the energy consumption is effectively reduced, and the urgent needs of energy conservation and emission reduction and environmental improvement are better met.
Description
Technical field: the present invention relates to a kind of crankshaft gear, specifically a kind of planet wheel participates in bent axle work, the bending moment planetary crankshaft that delivery efficiency significantly improves.
Background technique: at present, because planet wheel does not transmit motion, conventional crankshafts does not have planet wheel participation work, delivery efficiency can not significantly improve.
Summary of the invention: in order to change the state of the art, the invention provides one utilizes planet wheel as leading dirivig member, according to planet wheel characteristic and mechanics principle, by the change of planet wheel with the time is instantaneous, the force bearing point of space relative constancy is selected, the adjustment of input, output angle speed, linear speed, strengthens speed of crankshaft, increases moment of torsion, save former Input Forces, significantly improve the bending moment planetary crankshaft of transmission efficiency.
The technological scheme that technical solution problem of the present invention adopts is: comprise the ring gear 2 in crankcase 1 and case, crank 3, double-planetary gear 4, export sun gear 5, crankshaft main journal 6.Double-planetary gear 4 is installed on the rod journal outboard crank 3 of crankshaft output end, bull wheel in double-planetary gear 3 and ring gear 2 internal messing, steamboat and the outer gearing of output sun gear 4, export the terminal output wheel that sun gear 4 is crankshaft horsepower, the axle center of output sun gear 5 and crankshaft main journal 6 axle center are on same geometrical axis; Crank 3 also installs the double-planetary gear identical with double-planetary gear 4 structure by crankshaft main journal 6.Take turns to separate with fixed and moving axle sun gear by double-planetary gear large and small and engage, have adjusted former bent axle and the speed ratio exporting sun gear, add active torque, moment of torsion strengthens, and achieves the object improving delivery efficiency.
Beneficial effect of the present invention is: novel form is unique, simple and reasonable and have irreplaceability, and transmission performance is reliable and stable, and test proves: basic transmission efficiency improves more than 11%.Better meet the active demand of energy-saving and emission-reduction, environmental protect.
Accompanying drawing illustrates: below in conjunction with Figure of description, the invention will be further described.
Fig. 1 is plan view of the present invention
Fig. 2 is left view of the present invention
In Fig. 1,1. crankcase, 2. ring gear (dead axle sun gear), 3. crank, 4. double-planetary gear, 5. export sun gear.In Fig. 2,6 crankshaft main journals.
Embodiment: in the specific embodiment shown in Fig. 1, in crankcase 1, ring gear 2 (dead axle sun gear) is installed, double-planetary gear 4 is installed outside rod journal, the bull wheel of double-planetary gear 4 and ring gear 2 internal messing, steamboat engages with output sun gear 5 outer (interior), exports the terminal output wheel (axle) that sun gear 5 is bending moment planetary crankshaft.Drive duplex planet 4 one aspect around Pivot Point Center rotation when crank 3 rotates, another aspect flexing shaft neck 6 axle center revolution also driver output sun gear 5 is rotated, and double-planetary gear 4 steamboat driver output sun gear 5 rotates output power.
In double-planetary gear 4, axle center is former working force input point, fulcrums with the contact points of ring gear 2, fulcrum is input pivoted arm to the distance (radius) in axle center, fulcrum is export pivoted arm to the contact points (double-planetary gear 4 radiuses+steamboat radius) with steamboat, although export pivoted arm to be greater than input pivoted arm, but according to Transmission Ratio of Planetary Gear Trains rule, the speedup exporting the rotation of sun gear 5 is always greater than the rotating speed of crank 2, therefore, add input torque, save Input Forces, improve transmission efficiency.
In the embodiment shown in Figure 2, crank 3 by crankshaft journal 6 and at the identical double-planetary gear 4 of the other end mounting structure, in order to uniform force rotary balance, crank 3 also can be multiple being evenly arranged, and because their structures are the same, stressed situation is identical, so, do not mark in figure.
