Abstract
Variable speed planet axle transmission system is including input planet axle, dead axle sun gear, planet wheel, planet axle and output sun axle. The planet wheel install the moving axis sun epaxial and with dead axle sun meshing, the planet has taken turns to planet axle and output sun hub connection. According to planet wheel characteristic and mechanics principle, the adjustment of, differential surface speed fast through the angle of input and output, the increase of initiative rocking arm has been saved the input and has been done all can, has improved transmission efficiency. This kind of variable speed planet axle transmission system who utilizes the planet crop rotation to take transmission component transmitting torque as the leading factor has opened planet wheel transmitting torque's the beginning, the form novel unique, simple structure is equitable, the stable performance is reliable, the transmission effect improves obviously, the better active demand of satisfying energy saving and emission reduction, enhancement of environment, but the wide application is in the mechanical transmission of various power machines such as automobile, train (listing at a high speed), aviation, military project, boats and ships, wind power generation, heavy machinery, robot.
Description
Technical field: the utility model relates to a kind of planetary gear train drive device, specifically a kind of variable speed planetary shaft transmission system improved as leading dirivig member, transmission efficiency by planet wheel.
Background technique: at present, known planet wheel is transmitting torque and rotating speed not, be just used as speed change, turn to, along separate routes, the composition and decomposition etc. of power; Planet wheel is supported by planet carrier, adds dirivig member, increases raw material manufacture cost and power transmission cost; Input, output speed ratio are only changed by the change of the number of teeth.
Summary of the invention: in order to change the state of the art, the utility model take planet wheel as research and development objects, utilizes planet wheel as leading dirivig member transmitting torque, by installing planet axis and Direct driver output solar shaft on planet wheel, strengthen initiatively pivoted arm, improve transmission efficiency.Goal of the invention: one is adjustment input, output line speed ratio, and more torque, saves Input Forces, improves transmission efficiency; Two is reduce parts, material, processing, transmission cost.It is according to planet wheel characteristic and mechanics principle, by characteristics such as each point cycloid, cycloid, more complicated space curves on planet wheel, the input point of the power of instantaneous on select time on planet wheel, space relative constancy, adjustment input and output differential surface speed, strengthen the active pivoted arm of planet wheel, reach saving Input Forces, improve the object of transmission efficiency.
The technological scheme that the utility model technical solution problem adopts is: in planetary gear train transmission, comprises input solar shaft 1, dead axle sun gear 2, planet wheel 3 and exports solar shaft 4.Planet wheel 3 is arranged on input solar shaft 1 and engages with dead axle sun gear 2 (inside and outside), and planet wheel 3 is installed planet axis 5, and planet axis 5 is connected with output solar shaft 4 moving axis and Direct driver exports solar shaft 4; Input solar shaft 1 and output solar shaft 4 axis coinciding.
The utility model beneficial effect is: novel form is unique, simple and reasonable, stable and reliable for performance, and test proves: basic transmission efficiency improves more than 7%.Better meet the active demand of all kinds of power machine energy-saving and emission-reduction, environmental protect.
Accompanying drawing illustrates: below in conjunction with Figure of description, the utility model is described in further detail.
Fig. 1 is the utility model plan view
Fig. 2 is left view of the present utility model
In Fig. 1,1. input solar shaft, 2. dead axle sun gear, 3. planet wheel, 4. export solar shaft, 5. planet axis.
Embodiment: in the specific embodiment shown in Fig. 1, installed rows star-wheel 3 on input solar shaft 1 also engages with dead axle sun gear (inside and outside), planet axis 5 on planet wheel 3 is connected with output solar shaft 4 moving axis, export solar shaft 4 under the driving of input solar shaft 1, rotated along Input Forces direction by the revolution of planet wheel 3 and planet axis 5.Solar shaft 1 integrates axle, sun gear, planet carrier.Planet axis 5 on planet wheel 3 with dead axle sun gear 2 the radius arbitrfary point of engaging outside direction, the center of circle install, mounting points is called " footpath point ", footpath point and force bearing point.In planet wheel 3, input pivoted arm equals planet wheel 3 center of circle to the distance with dead axle sun gear 2 contact points, the namely radius of planet wheel 3, export pivoted arm equal footpath point to dead axle sun gear 2 contact points distance, the arbitrfary point outside the non-center of circle is in, so input pivoted arm is greater than output pivoted arm forever due to footpath point, meet saving Input Forces, improve the condition of transmission efficiency.Footpath point is more away from the center of circle, and efficiency improves larger, and vice versa.In the process of planet axis 5 driver output solar shaft 4, because planet wheel 2 is fixed on input solar shaft 1, planet axis 5 one aspect and planet wheel 3 are fixed, be connected with output solar shaft 4 moving axis on the other hand, so, input solar shaft 1 and output solar shaft 4 jiaos of speed are equal, but, input solar shaft 1 and export solar shaft 4 the diameter of axle (distance of the mounting points of planet wheel 3 axle center and planet axis 5) not etc., therefore, when output solar shaft 4 linear velocity is greater than the linear velocity of input solar shaft 1, input torque is added, save Input Forces, improve transmission efficiency.
In the embodiment shown in Figure 2, when planet axis 5 is fixed on planet wheel 3, with export solar shaft 5 that installation form has dead axle axle sleeve type, non-dead axle rolls the formula of driving etc. is multiple.Dead axle axle sleeve type and bearing shaft are arranged on and export on solar shaft 4, and planet axis 5 is fixed on axle sleeve; Non-dead axle rolls the formula of driving and planet axis 5 directly installs bearing, and bearing housing and friction rolling in the scroll zones space exported on sun gear 4, planet wheel 3 is less, and planet axis 5 is nearer apart from the distance in planet wheel 3 center of circle, and scroll zones space is less.Structure, stressed identical planet wheel 3 and planet axis 5 can be several being evenly distributed on respectively on input solar shaft 1 and planet wheel 3.
