The invention relates to moment changing machine. It includes fixed center shaft, center gear wheel, and many planet gears. The planet gear is set on gear support. Its features are that the total number of the center gear wheel and planet gear is equal to three or more; and it also includes one inner gear wheel. The invention can change the moment to improve mechanical efficiency and save energy sources.
Description
Technical field
The present invention relates to a kind of by rotating the mechanical device of transmission of drive force.
Background technique
Usually be to be delivered to working portion with the driving force that parts such as transmission shaft, gear, lever produce power source to go counterbalance resistance to accomplish the end in view by the device that rotates transmission of drive force.These media partly are indispensable, but it consumes part power simultaneously inevitably, thereby have reduced power.Traditional method all is to adopt loss that different structure, material or different lubricating systems reduce this part improving mechanical efficiency, though time to the greatest extent down, it is limited to produce effects, and loses more or less inevitable.
The present invention proposes in view of the problems of the prior art.Purpose is that the power of this part loss is reduced as far as possible, in the hope of reaching the effect of saving the energy.
Summary of the invention
For achieving the above object, the invention provides a kind of torque converter, comprise: fixing central shaft, be fixed on the central gear on the central shaft, with with the central gear be a plurality of planetary pinions that mesh in order at the center, and the planetary pinion of maximum sequence number can be duplicate gear or individual gears, described planetary pinion is installed in can be on the gear stand of central shaft rotation, it is characterized in that: described central gear and described planetary total number are equal to or greater than three, also comprise an internal gear that is positioned on the support that can center on the central shaft rotation, its Gear center is not on the axis of central shaft, its inner ring wall contacts with central shaft, and simultaneously with the planetary pinion engagement of maximum sequence number.
For simplicity, below only central gear and two planetary pinion diameters are consistent and second planetary pinion is individual gears situation are described, other state is because of mechanism unanimity, explanation no longer one by one.
Transfer unit of the present invention adopts one and fixing central gear and first, second two planetary pinions of central shaft can to combine around the gear stand that fixing central shaft rotates by one, adds that an inner ring wall contact with central shaft and and the internal gear composition that meshes simultaneously of second planetary pinion again.First, second planetary pinion and gear stand can be simultaneously around the central gear rotation, internal gear can around central shaft do eccentric rotary and and gear stand be synchronized with the movement.Be applied to and rotate and by the internal gear and the second planetary contact points resistance to be applied on second planetary pinion around central shaft with resisting moment on the crank that internal gear contacts, because the effect of lever, the pin that this resistance is connected with gear stand by second planetary pinion is delivered on the gear stand, and gear stand is formed a resisting moment.Because the second planetary pin arrives the distance of central shaft less than the contact points of second planetary pinion and internal gear to the distance of central shaft, again because power is identical, so this is less than the former resisting moment that is applied on the internal gear to the resisting moment that gear stand produces.The resistance that is applied to simultaneously on second planetary pinion also is delivered on first planetary pinion, because the contact points of the effect of lever and first planetary pinion and central gear acts on to the first planetary reaction force time, on first planetary pinion and pin that gear stand is connected, gear stand is produced an opposing torque, this opposing torque is opposite to the moment direction that gear stand produces to the second planetary reaction force with first planetary pinion, is in the counteracting state.The final resisting moment that still gear stand is produced is less than the former resisting moment that is applied at first on the internal gear.Be applied to just can contend with on the gear stand with the small driving force square and formerly be applied to resisting moment bigger on the internal gear what diminished on the gear stand.
Central gear and be that to mesh the planetary sum that is installed on the gear stand in order be number greater than three at the center with the central gear, add that an inner ring wall contacts with central shaft and simultaneously with the structure of the internal gear of the planetary pinion engagement of maximum sequence number, because of the mechanism unanimity, can reach same effect.
This torque converter is a kind of by an internal gear, a central gear and two mechanical devices that planetary pinion is meshing with each other and forms.Except that the routine effect of fulcrum, owing to utilized the point of mesh that can center on the central gear rotation, make moment change, thereby reach the raising mechanical efficiency again as the fulcrum role, save the effect of the energy.
A plurality of these devices can serial fashion use, promptly with the output of the front device input as the back device, to reach better effect.
Based on above reason, only the structure of two planetary pinions and an internal gear on a central gear and the gear stand is described for example.
Description of drawings
Fig. 1 is the side view according to torque converter of the present invention;
Fig. 2 is the plan view of torque converter shown in Figure 1.
Embodiment
Embodiments of the present invention are described with reference to the accompanying drawings.
As shown in drawings, central shaft is fixed, three gear 1,2,3 diameter unanimities, and central gear 1 and central shaft are fixed, first planetary pinion 2 and central gear engagement, second planetary pinion 3 and 2 engagements of first planetary pinion.First planetary pinion 2 and second planetary pinion 3 combine with the gear stand that can center on the central shaft rotation with bearing and pin mode.The inner ring wall of internal gear 4 contacts with central shaft simultaneously and second planetary pinion 3 is meshed.
When resistance is applied to the internal gear 4 of internal gear 4 and second planetary pinion, 3 contact points places, internal gear 4 has applied resistance by the pin of 3 pairs second planetary pinions 3 of second planetary pinion, because of the contact points of the internal gear 4 and second planetary pinion 3 is 5R (radius of establishing gear 1,2,3 is R) to the distance of central shaft, and the pin place of second planetary pinion 3 is 4R to the distance of central shaft, so the resisting moment that gear stand is formed be 45, rather than 1.And the pin of first planetary pinion 2 and gear stand junction, because of first planetary pinion, 2 pin places are 2R apart from central shaft, and be subjected to a power from second planetary pinion 3, also be subjected to the reaction force of central gear 1 simultaneously, the opposing torque that 2 power and 2R cause be 45; Because the reaction force of 2 pairs second planetary pinions 3 of first planetary pinion, the moment that second planetary pinion, 3 pins and gear stand junction are caused also be 45; The moment that this both direction is opposite, size is identical is cancelled each other using.In addition 15 resisting moment act on the central gear 1, and act on the fixing central gear 1 this 15 resisting moment be delivered on the pedestal by fixing central shaft, by pedestal this part resisting moment of having contended with.Final result has applied 1 resisting moment to internal gear 4, and is 45 to the actual resistance square that gear stand causes.
For the ordinary skill in the art, can easily expect other advantage and modification.Therefore, the present invention in wide range more is not restricted to specific detail and representation example shown and that describe here.Therefore, in the spirit and scope that do not depart from by following claim and their universal of the present invention that equivalent limited, can make various changes.
