Measure equal, intermesh arrangement, and the high-low pressure volume unit constructed in this way can also increase.Section is connected between two kinds of volume units
Circulation road, throttling passage connection high pressure volume unit, settable throttle valve realizes constant-power speed regulation on throttling passage, works as differential gear
It fastens when being cased with shell, throttling passage is drawn out on shell advantageously by side plate, axle journal to be arranged convenient for throttle valve.This is let out due to interior
Body is also a kind of throttling process, therefore throttling passage is also possible to the leakage channel between high-low pressure volume unit, or in side plate
On tiny channel is artificially set, such case does not need to adjust the speed using valve, at this moment the present invention be similar to have speed regulation energy
The shaft coupling of power, be suitable for operating condition it is fairly simple under conditions of.
The construction of the present invention and earlier application is substantially similar, and the main distinction is that sealing gear 19 has been used to replace spacing block
Effect, in advance understand earlier application in construction and scheme, help to better understand the present invention.
As earlier application with transmission principle of the invention is, here again illustratively:
Dynamic unit such as oil pump and execution unit such as oil cylinder, oil motor etc. in hydraulic drive pass execution unit
Meet volume maximization principle when dynamic and not only meet motor effect for power unit referred to herein as motor effect, if tool
Standby condition, also meets pump efficiency and answers, that is, when driving power unit, if there is multi-motion approach generates different discharge capacities, then can become
To in oil liquid decrement minimize, pump efficiency should be with the common purpose of motor effect it is identical, exactly make oil pressure minimum prevent from holding
Continuous to rise, so pump efficiency the another of motor effect should show in fact, conventional pump class can not embody pump efficiency and answer, because it
Only a kind of compressing way.A kind of technical solution of discharge capacity difference is provided in earlier application, side plate and spacing block combine three kinds
Gear, that is, ring gear 21, sun gear 22 and planetary gear form high-low pressure volume unit, and when driving sun gear 22, planetary gear both may be used
Rolling revolution can also be done by fulcrum of ratcheting point, the arm of force of both motion modes is different around center rotation itself
, it is clear that when as power unit, the oil mass of rotation compression is greater than revolution, is answered according to pump efficiency, differential gear train can tend to public affairs
Turn that planet carrier component is made to obtain output torque.Only meet pump efficiency should be it is inadequate, input terminal or output end must have superposition
Resultant moment, which can just have to become, turns round effect, in earlier application, when planet carrier component, which connects, to be loaded and drive sun gear 22 clockwise, and height
Pressure-volume product unit can only construct on the right side of planetary gear, and at this moment input torque, pumping forces square and motor torque direction are all identical, fold
Planet carrier component can be enable to obtain the identical resultant moment output in direction after adding, resultant moment size is also different when oil pressure difference, institute
Turned round with being able to achieve to become, if high pressure volume building unit in the left side of planetary gear, being answered by gear modification generation pump efficiency
There can not be the resultant moment of superposition to export always, it is at this moment exactly invalid.The scheme of earlier application has been subjected to physical varification, according to
It is easy for understanding the present invention described in upper, referring to fig. 2, spacing block is eliminated in the present invention using sealing gear 19 to substitute, if
Driving sun gear 22 clockwise, transmission gear 20 meets pump efficiency and answers and have resultant moment, (oil suction when (pressure oil QA- oil suction QB) > 0
QD- pressure oil QC) > 0 when sealing gear 19 meet motor effect, due to motor effect generate torque depend on effective discharge, and
(oil suction QD- pressure oil QC) very little, therefore the opposing torque very little that motor effect is generated because of self-interference, when total displacement relationship meets
It when (pressure oil QA- oil suction QB) > (oil suction QD- pressure oil QC), can be achieved with being driven, at this moment the effect of sealing gear 19 and first Shen
Please in spacing block it is equivalent.In the identical situation of some parameters of gear, the addendum coefficient of transmission gear 20 is made to be greater than sealing
Gear 19 is able to satisfy total displacement relationship.
On the basis of above scheme, the present invention has following preferred or optinal plan:
Transmission gear 20 is different with the sealing addendum coefficient of gear 19.This is to adjust the ideal hand of total displacement relationship
Section, the pressure angle for increasing gear can increase difference.If gear is by means such as displacements, the heart is away from downward entire row amount in a standard
It is intended to zero for official post, at this moment by the center of transmission gear 20 away from increase, by the center for sealing gear 19 away from having (pressure after reduction
Oily QA- oil suction QB) > 0, (pressure oil QC- oil suction QD) > 0, it is also able to satisfy pump efficiency in this way and answers, but this way needs to increase backlash,
And gear is also prone to wear.
Side plate includes front side board 11, floating side plate 12 and back side panel 17, is connected with row between front side board 11 and back side panel 17
Spider gear shaft 15, floating side plate 12 are set on planet wheel spindle 15.Floating side plate 12 mainly plays end face compensation, leads in high pressure
Domain, which has been widely used, can significantly improve volumetric efficiency, since sealing gear 19 has ratcheting sealing and end face compensation, sealing effect
Fruit can be better than the scheme of spacing block.End face and ratcheting gap can be eliminated by adjustment or grinding after present invention assembling, if work
When in oil liquid be added metal self repairing agent, can further eliminate slight gap and strengthen contact performance, this be also the present invention

But due to physical presence manufacture or wearing clearance etc., this 6 points can only at most have 5 contacts under hard conditions, even together
When having multiple, 3 points of each planetary gear not can guarantee while contacting kind planetary gear, although planetary gear of the same race can pass through
Adjustment improves, but because the relative position of contact point is different, different planetary gear adjustments is also invalid.If e point is made not contact phase
When being solid construction in sealing gear 19, but ratcheting position stress is huge in this case, in order to ensure sealing effect and supports
The lateral pressure of planetary gear reaches 6 point contacts in practice and is necessary, when planetary gear connects planetary gear by excentric sleeve 18
The function of automatic position adjusting function can be provided with after axis 15, this eccentricity generally only needs very little.In engineering, planet can also be made
Method that wheel shaft 15 suspends solves this problem, i.e. the both ends of planet wheel spindle 15 are by oil cylinder connecting lateral plate, but oil cylinder volume
There are many big disadvantage.
