Technical field: the utility model relates to a kind of planet gear transmission system, specifically a kind ofly changes torque and does not have planet carrier to improve the planet gear transmission system of transmission efficiency.
Background technique: at present, known planetary gear train transmission is just used as speed change, turns to, along separate routes, the composition and decomposition etc. of power, planet wheel is not as leading dirivig member; Planet wheel is supported by planet carrier, adds dirivig member, increases raw material manufacture cost and power transmission cost; Cannot realize angle speed, linear speed speed poor; Can not driving torque be changed, save Input Forces, improve transmission efficiency.
Model utility content: in order to change the state of the art, the utility model provides a kind of planet wheel not have planet carrier to be directly installed on moving axis sun gear, strengthens planet wheel radius, improves the multistage planet train transmission system of transmission efficiency.Main purpose: according to planet wheel characteristic, particularly take turns characteristic and the mechanics principles such as upper each point movement locus cycloid, cycloid, complicated space curve, power input point that is instantaneous on the Input Forces set direction time, spatially relative constancy, adopt planet wheel as leading dirivig member driving torque, strengthen planet wheel radius, increase moving axis sun gear initiatively pivoted arm, under input, output angle speed equal, the linear speed prerequisite such as not, strengthen active torque, save Input Forces, improve transmission efficiency; Planet wheel does not have planet carrier to be directly installed on sun gear, and sun gear substitutes planet carrier, saves raw material, processing, transmission cost.
The technological scheme that the utility model technical solution problem adopts is: comprise by row of variables star-wheel 2, input moving axis sun gear 1, dead axle sun gear 5 form line of input star wheel series and by quantitative planet wheel 3, export the output planetary train that the moving axis sun 4 forms, the planet gear transmission system that two trains are formed jointly, two trains are arranged in a geometrical central axis 6 overlapped, row of variables star-wheel 2 do not have planet carrier to be directly installed on moving axis sun gear 1 and with dead axle sun gear 5, in the while of quantitative planet wheel 3, outer gearing, quantitative planet wheel 3 do not have planet carrier to be directly installed on to export yet on moving axis sun gear 4 with row of variables star-wheel 2 outer gearing, input moving axis sun gear 1 and output moving axis sun gear 4 are respectively original wheel for inputting and terminal output wheel.
Row of variables star-wheel 2 is force bearing points with the outer gearing point 7 of quantitative planet wheel 3, force bearing point 7 row of variables star-wheel 2 active force set direction and be less than the radius of row of variables star-wheel 2 to the crow flight distance of dead axle sun gear 5 contact points 10; The variable intension of row of variables star-wheel 2 is changes of radius size, and dead axle sun gear 5 radius, output moving axis sun gear 4 radius change thereupon simultaneously, exports its linear velocity when moving axis sun gear 4 radius changes and changes, increase input torque;
The utility model beneficial effect is: novel form is unique, simple and reasonable and have irreplaceability, and stable and reliable for performance, overload capacity is powerful, and working life is longer, saves material, processing, transmission cost.Test proves: adopt speed changer, transmission case, solar shaft etc. that the utility model technology is produced, save Input Forces, improve transmission efficiency, can in the mechanical transmission of all kinds of power machine of extensive use, better can meet the demand of energy-saving and emission-reduction, environmental protect, achieve model utility innovation object.
Accompanying drawing illustrates: below in conjunction with Figure of description, the utility model is described in further detail.
Fig. 1 is plan view of the present utility model.
Fig. 2 is the left view of Fig. 1.
Fig. 3 stressed schematic diagram of the present utility model.
In Fig. 1-3,1. input moving axis sun gear, 2. row of variables star-wheel, 3. quantitative planet wheel, 4. export moving axis sun gear, 5. dead axle sun gear (gear ring), the geometrical central axis 6. overlapped, 7. force bearing point, the 8. mounting points of planet wheel 2, the 9. mounting points of planet wheel 3.10. the contact points of row of variables star-wheel 2 and dead axle sun gear (gear ring) 5.
Embodiment: in the embodiment shown in fig. 1, row of variables star-wheel 2, input moving axis sun gear 1, dead axle sun gear (gear ring) 5 are input train, and quantitative planet wheel 3 and output moving axis sun gear 4 are output wheel train.Row of variables star-wheel 2 do not have planet carrier to be directly installed on moving axis sun gear 1 simultaneously with dead axle sun gear 5, quantitatively planet wheel 3 is inside and outside engages.Quantitative planet wheel 3 not have planet carrier to be directly installed on to export on moving axis sun gear 4 yet and with row of variables star-wheel 2 outer gearing.Input moving axis sun gear 1 is taken turns (axle) for initial input and is docked with power engine, exporting driving wheel sun gear 4 is that terminal output wheel (axle) docks with working machine, input driving wheel sun gear 1 drives variable planet 2, utilizes row of variables star-wheel 2 to revolve round the sun the quantitative planet wheel 3 of property driving and export moving axis sun gear 4 and rotate.Row of variables star-wheel 2 are double-planetary gears with ensure one with dead axle sun gear 5 internal messing, the outer gearing of another and quantitative planet wheel 3.Can be wheel shaft with the row of variables star-wheel of quantitative planet wheel 3 outer gearing and quantitative planet wheel 3, diaxon rolling friction.Two planet wheel contact pointss 7 are called force bearing point, and force bearing point 7 will at row of variables star-wheel 2 active force set direction, and force bearing point 7, contact points 10 crow flight distance are less than the radius of row of variables star-wheel 2.
In specific embodiment shown in Fig. 2, the left apparent time overlap of row of variables star-wheel 2, the quantitatively engagement of planet wheel 3, could not show in figure.Row of variables star-wheel 2 and quantitative planet wheel 3 all do not have planet carrier be directly installed on input moving axis sun gear 1 respectively and export on moving axis sun gear 4, save material, processing and transmission cost.
In specific embodiment shown in Fig. 3, strengthen row of variables star-wheel 2 radius, input moving axis sun gear 1 radius does not change, namely the center of circle does not change to the distance in row of variables star-wheel 2 center of circle, but dead axle sun gear 5 and output moving axis sun gear 4 radius will strengthen thereupon, during output moving axis sun gear 4 enlarging radius, its linear velocity strengthens naturally, therefore, under the size not changing input moving axis sun gear 1 and speed conditions, increase the radius, linear speed and the moment of torsion that export moving axis sun gear 4, improve transmission efficiency.Row of variables star-wheel 2 radius changes and will determine according to the working space of system, such as; Micro-transmission such as robot, clock and watch wants less relatively; Train, boats and ships, engineering machinery etc. want large relatively.
In order to stability of rotation and reduction tooth damage, row of variables star-wheel 2, quantitatively planet wheel 3 can be that several being evenly distributed on inputs moving axis sun gear 1 and export on moving axis sun gear 4, because drive mechanism is identical, do not mark in this Figure of description.
