Abstract

Epicycle train regid mechanism is the special gear mechanism of a kind of structure, two sun gears in its three basic dirivig members, and after input is determined with output, mechanism's self-locking one all the time.If another member planet carrier of control is fixed it, mechanism gets final product converting motion, realizes the speed change transmission.It is a kind of variable transmission mechanism that does not have the neutral transition, it is high-power big moment secondary starting mechanism in the power transmission, be applicable to that input and output are subjected to synchronous requirement restriction and inconvenience to establish neutral and clutch, must often start again, constantly change the occasion of output speed.

Description

Epicycle train regid mechanism

The present invention is a kind of mechanical train driving mechanism.

This mechanism has the kinetic characteristic of epicyclic gear train transmission, after two sun gears are determined an output and an input in its three member, mechanism becomes one all the time from trivial rigid body, if another member planet carrier of control, it is maintained static, slip promptly takes place with output and realizes the speed change transmission in input, it is a kind of variable transmission mechanism that does not need the neutral gear transition, be applicable to that input is subjected to require to place restrictions on inconvenience synchronously to establish neutral and clutch with output in the power transmission, must often change the control and the automation control occasion of output speed again.

The present invention makes on epicyclic gear train 2K-H positive sign mechanism basis, through preliminary search, the mechanical transmission aspect does not still have this mechanism and application example both at home and abroad, relevant epicyclic gear train positive sign mechanism related to the present invention can be consulted this class publication of Der Grundsatz der Maschinen and mechanical mechanism " epicyclic gear train mechanism " chapter.

Task of the present invention:, enlarge the application area of epicyclic gear train mechanism for further enriching, deepen, enrich the transmission content of epicyclic gear train mechanism.

Shown in the composition accompanying drawing of this mechanism, small sun gear (1), big sun gear (2) and planet carrier (3) are all on same axes O O, planet carrier (3) is gone up by adorning the double compound planetary wheel (6) that the number of teeth equates, and the breast wheel (5) and the breast wheel (4) of series connection with it engagement, wherein planet wheel (6) meshes with big sun gear (2) again, breast wheel (4) meshes with small sun gear (1) again, small sun gear among the figure (1), big sun gear (2) and planet carrier (3), being referred to as this gear mechanism can both be around motion three member of OO axis commentaries on classics, and planet carrier (3) is fixing in this three member, and mechanism can make ordinary transmission.

When small sun gear (1) initiatively, when big sun gear (2) was driven, velocity ratio was:

i＝ (Z4)/(Z1) × (Z5)/(Z4) × (Z6)/(Z5) × (Z2)/(Z6)

When big sun gear (2) initiatively, when small sun gear (1) was driven, velocity ratio was:

i＝ (Z6)/(Z2) × (Z5)/(Z6) × (Z4)/(Z5) × (Z1)/(Z4)

If a sun gear is fixed in mechanism's three members, planet carrier (3) initiatively, two breast wheels on planet carrier this moment (3) and planet wheel (6) are under the drive of planet carrier (3), on the one hand around the OO rotational, on the other hand around oneself rotational, drive another sun gear output simultaneously, make Gear Planet Transmission.

When small sun gear (1) fixing, planet carrier (3) initiatively, velocity ratio was when big sun gear (2) was driven:

$\mathrm{i\; =}\frac{1}{\mathrm{1-}\frac{\mathrm{Z6}}{\mathrm{Z2}}\times \frac{\mathrm{Z5}}{\mathrm{Z6}}\times \frac{\mathrm{Z4}}{\mathrm{Z5}}\times \frac{\mathrm{Z1}}{\mathrm{Z4}}}$

When big sun gear (2) fixing, planet carrier (3) initiatively, velocity ratio was when small sun gear (1) was driven:

$\mathrm{i\; =}\frac{1}{\mathrm{1-}\frac{\mathrm{Z4}}{\mathrm{Z1}}\times \frac{\mathrm{Z5}}{\mathrm{Z4}}\times \frac{\mathrm{Z6}}{\mathrm{Z5}}\times \frac{\mathrm{Z2}}{\mathrm{Z6}}}$

If a sun gear initiatively in mechanism's three members, another sun gear is driven, planet (6) on another member planet carrier (3) is with on the calibration garden, one side at this moment, be subjected to the effect of driving link and driven member active force and reaction force, because the number of teeth of this double compound gear of planet wheel (6) is identical, the arm of force equates, suffered active force and reaction force be opposite sign but equal magnitude again, so the opplied moment on the double compound planetary wheel (6) equates with the moment of reaction, there is not torque difference, thereby make planet wheel (6) keep transfixion, tight trivial one-tenth one rigid body of mechanism's three members balance in static(al), velocity ratio is considered as i=1.

As seen this Epicycle train regid mechanism, the kinetic characteristic that has kept epicyclic gear train 2K-H positive sign mechanism, have again all the time from trivial all-in-one-piece ability, it not only can make gearing down in transmission, the speedup transmission, and can also make mechanism do direct transmission, and can change its type of belt drive with simple controlling method, the rigid body transmission is transformed into ordinary transmission, and the 2K-H positive sign mechanism is with a certain type of belt drive, mechanism also may take place from trivial when reaching a certain velocity ratio, but if this when converting ordinary transmission to from trivial state with mechanism, its velocity ratio is minimum, little to nonsensical, so no application example.

Obviously, Epicycle train regid mechanism is the same with epicyclic gear train mechanism, all is self-existent driving mechanism, has certain application value, therefore implementing the present invention can directly use above working principle, according to purposes and transmission requirement, designs the gear with various specific uses.
