1、无级变速器的公转是具备实施外加控制性能，此技术方案的两端行星齿轮组，在腔体行星架之外，即腔体输入端盖、腔体输出端盖之外，两端行星齿轮组限定了端盖的位置，很难对腔体行星架两侧端盖的公转实施控制。
2、无级变速器腔体行星架内部含有油液，具备富油润滑的条件，此技术方案的两端行星齿轮组，在腔体行星架之外，即腔体输入端盖、腔体输出端盖之外，两端行星齿轮组的齿轮啮合传动，贫油润滑，噪声大。
3、无级变速器的行星轮轴与斗轮行星轮轴不是同轴心，行星轮轴在 斗轮行星轮轴的中心之外，此结构布置复杂。
4、无级变速器具备输入端、输出端互换形成不同的传动性能，适应不同的场合，此结构固定了输入端和输出端，造成传动性能单一。
5、中间壳体的内壁结构是无级变速器功能结构，其形状决定了斗轮扭矩传输能力，此技术方案没有中间壳体的内壁结构方案。
6、需要增大扭矩传输时，在其他结构不变的情况下，没有提供采用齿圈代替太阳轮方案，增大扭矩传输，无级变速器结构复杂、不能实现多功能和满足不同工况。

具体实施方式
下面结合实施例对本发明做进一步描述。
实施例1
如图1-图6所示，是本发明一种无级变速器的实施例，其设有外壳体1，外壳体1中间设有中间壳体101，中间壳体101两侧分别设有第一端盖102和第二端盖103，中间壳体101内部为空腔结构，中间壳体101内部的空腔与第一端盖102和第二端盖103的内侧形成内腔体2；第一端盖102中间贯穿设有第一轴3，所述第一轴3与第一端盖102旋转连接，第一轴3上固定设有第一太阳轮401，第一太阳轮401位于第一端盖102内侧，第一太阳轮401相邻设有第一支撑架5，第一轴3穿过第一支撑架5，第一轴3与第一支撑架5旋转连接；第一太阳轮401外圆周上设有第一行星轮402，第一行星轮402与第一太阳轮401啮合连接，第一行星轮402和第一太阳轮401构成第一行星齿轮组4；第二端盖103中间贯穿设有第二轴6，所述第二轴6与第二端盖103旋转连接，第二轴6上固定设有第二太阳轮701，第二太阳轮701位于第二端盖103内侧，第二太阳轮701相邻设有第二支撑架8，第二太阳轮701外圆周上设有第二行星轮702，第二行星轮702与第二太阳轮701啮合连接，第二行星轮702和第二太阳轮701构成第二行星齿轮组7；穿过第一支撑架5的第一轴3上固定设有斗轮太阳轮1001，斗轮太阳轮1001位于第一支撑架5内侧，斗轮太阳轮1001外圆周上设有斗轮行星轮1002，斗轮行星轮1002与斗轮太阳轮1001啮合连接，斗轮行星轮1002和斗轮太阳轮1001构成斗轮行星齿轮组10；斗轮太阳轮1001相邻设有第三支撑架11；斗轮行星轮1002中间固定设有斗轮行星轮轴14，斗轮行星轮轴14内部为空心结构，斗轮行星轮轴14穿过第三支撑架11，斗轮行星轮轴14与第三支撑架11旋转连接，穿过第三支撑架11的斗轮行星轮轴14上固定设有斗轮901，斗轮 901位于第三支撑架11与第二支撑架8之间，多个斗轮行星轮轴14上固定设有的斗轮901构成斗轮组9；第一行星轮402中间固定设有行星轮轴12，行星轮轴12穿过第一支撑架5、空心的斗轮行星轮轴14、第二支撑架8，所述行星轮轴12分别与第一支撑架5、第二支撑架8旋转连接，穿过第一支撑架5、空心的斗轮行星轮轴14、第二支撑架8的行星轮轴12与第二行星轮702固定连接。
本实施例中，无级变速器设有外壳体1，外壳体1中间设有中间壳体101，中间壳体101两侧分别设有第一端盖102和第二端盖103，中间壳体101内部为空腔结构，中间壳体101内部的空腔与第一端盖102和第二端盖103的内侧形成内腔体2，无级变速器自身具备公转加自转的性能，在外壳体1上施加制动力，可以控制无级变速器的公转，外壳体1可以作为控制调节无级变速器传动性能的控制端，第一轴3、第二轴6和外壳体1三者可以实现互相调节的功能，也就是说，可以将第一轴3、第二轴6和外壳体1三者中，任选其一作为动力的输入端，其余两端作为控制整体无级变速器性能的控制端，例如如果将第一轴3作为动力的输入端，第二轴6作为动力的输出端，此时可以将外壳体1作为第三控制端使用，当在传输扭矩能力不足时，外壳体1作为第三控制端参与制动，将大大提升无级变速器的传递性能。
同时第一轴3、第二轴6作为动力的输入端或动力的输出端可以互相调换，互相调换后，无级变速器会呈现不同的性能。
图2中可以看到，斗轮行星轮轴14内部为空心结构，斗轮行星轮轴14与斗轮901可以为固定连接的分体结构，也可以做成一体结构，本实施例为一体结构，行星轮轴12穿过空心的斗轮行星轮轴14，使得整体结构非常紧凑，无级变速器的整体外形尺寸可以做的非常小，适合各种场合的应用；外壳体1内部设有内腔体2，形成了一个封闭的腔体，中间壳体101内可以填充适量油液，使得内腔体2的齿轮啮合富油润滑，可以降低齿轮磨损和噪声；
图3中可以看到，外壳体1内壁对应斗轮901位置设有半圆形状的 腔体，斗轮901位于半圆形状的腔体中，斗轮901位于外壳体1内壁半圆形状腔体内，斗轮901的液动力、液粘力将发挥更有效的性能，实现了结构的紧凑优化，同时满足更优良的性能。
该实施例的无级变速器的运行过程是，当启动时，设定动力从第一轴3顺时针输入，带动第一太阳轮401顺时针旋转，第一太阳轮401带动第一行星轮402逆时针旋转，通过固定连接的行星轮轴12带动第二行星轮702旋转，在第二太阳轮701受到来自第二轴6的阻力，第二行星轮702绕第二太阳轮701逆时针公转，带动第一支撑架5、第二支撑架8、第三支撑11和外壳体1的逆时针公转；同时第一轴3顺时针旋转，带动固定连接在第一轴3的斗轮太阳轮1001顺时针旋转，斗轮行星轮1002逆时针自转，进而带动斗轮901逆时针自转，斗轮901位于外壳体1内壁半圆形状腔体内，斗轮901逆时针自转在中间壳体101内受油液阻力形成扭矩，此阻力包括中间壳体101公转形成的液重力、离开斗轮901油液喷射给相邻斗轮901的液动力和斗轮901与外壳体1内壁半圆形状的腔体之间油液的液粘力，斗轮901形成的阻力扭矩同时传递给第一支撑架5、第二支撑架8和第三支撑11，通过第二行星轮702，形成阻止因第二轴6阻力造成公转的扭矩，进而带动第二行星轮702对第二太阳轮701受力，第二太阳轮701带动第二轴6输出动力，油液对斗轮901的阻力开始是0，随着第一轴3速度的增大，油液对斗轮901的阻力成倍增大，第二太阳轮701带动第二轴6旋转，进而通过第二轴6输出动力。
本实施例1的上述过程的启动初期，无级变速器为零速零扭矩启动，处于启动中期时，斗轮组9受到的阻力快速提升，其阻力最终作用第一支撑架5、第二支撑架8和第三支撑架11上，同时也作用在中间壳体101上，当输入为低转速状况，斗轮901提供的阻力不够，输出扭矩不理想时，对外壳体1的第一端盖102、第二端盖103和中间壳体101任意一端实施制动控制，通过制动外力阻止外壳体1的公转，可减少对斗轮901提供阻力的依赖，增大无级变速器的输出扭矩，当外壳体1处于半制动时，无级变速器实现无级变速功能，当外壳体1全制动时，无级变速器 实现减速机的功能；额定工况运转时，无级变速器的速度与扭矩相对稳定，斗轮901受力平衡不自转，相互间的齿轮不转动，整体实现动力的同步传输，趋近于1:1传动。以上各种应用形式灵活，可以通过设置不同的输入输出端以及控制端，实现各种领域的应用配置。
该系列无级变速器的第一行星轮402和第二行星轮702可以选用为3个以上，该实施例中，第一行星轮402和第二行星轮702分别为9个，可以根据传递功率的不同和使用尺寸的不同，设置不同数量的第一行星轮402和第二行星轮702，从而适应不同的应用要求，一般可以选用6个、9个、12个等不同的数量。
图3中还可以看到，第一轴3或第二轴6上固定设有中心斗轮13，中心斗轮13位于第二支撑架8和第三支撑架11之间，中心斗轮13的设置可以调节内腔体2中油液的运转模态，调节运转的性能。
实施例2
图7-12所示为本发明一种无级变速器的另一实施例，设有外壳体1，外壳体1中间设有中间壳体101，所述中间壳体101两侧分别设有第一端盖102和第二端盖103，所述中间壳体101内部为空腔结构，所述中间壳体101内部的空腔与第一端盖102和第二端盖103的内侧形成内腔体2；第一端盖102中间贯穿设有第一轴3，所述第一轴3与第一端盖102旋转连接，第一轴3上固定设有第一齿圈401A，第一齿圈401A位于第一端盖102内侧，第一齿圈401A相邻设有第一支撑架5，第一轴3穿过第一支撑架5，第一轴3与第一支撑架5旋转连接，第一齿圈401A外圆周内侧设有第一行星轮402，所述第一行星轮402与第一齿圈401A啮合连接，第一行星轮402和第一齿圈401A构成第一行星齿轮组4；第二端盖103中间贯穿设有第二轴6，第二轴6与第二端盖103旋转连接，第二轴6上固定设有第二齿圈701A，第二齿圈701A位于第二端盖103内侧，第二齿圈701A相邻设有第二支撑架8，第二齿圈701A外圆周内侧设有第二行星轮702，所述第二行星轮702与第二齿圈701A啮合连接，所述第二行星轮702和第二齿圈701A构成第二行星齿轮组7；穿过第一支撑架5 的第一轴3上固定设有斗轮太阳轮1001，斗轮太阳轮1001位于第一支撑架5内侧，斗轮太阳轮1001外圆周上设有斗轮行星轮1002，所述斗轮行星轮1002与斗轮太阳轮1001啮合连接，斗轮行星轮1002和斗轮太阳轮1001构成斗轮行星齿轮组10；斗轮太阳轮1001相邻设有第三支撑架11；斗轮行星轮1002中间固定设有斗轮行星轮轴14，斗轮行星轮轴14内部为空心结构，斗轮行星轮轴14穿过第三支撑架11，斗轮行星轮轴14与第三支撑架11旋转连接，穿过第三支撑架11的斗轮行星轮轴14上固定设有斗轮901，斗轮901位于第三支撑架11与第二支撑架8之间，多个斗轮行星轮轴14上固定设有的斗轮901构成斗轮组9；第一行星轮402中间固定设有行星轮轴12，行星轮轴12穿过第一支撑架5、空心的斗轮行星轮轴14、第二支撑架8，行星轮轴12分别与第一支撑架5、第二支撑架8旋转连接，所述穿过第一支撑架5、空心的斗轮行星轮轴14、第二支撑架8的行星轮轴12与第二行星轮702固定连接。
图8中可以看到，与实施例1不同的是，该实施例采用第一齿圈401A替代实施例1中的第一太阳轮401，第二齿圈701A替代实施例1中的第二太阳轮701，当动力由第一轴3或第二轴6输入时，由于第一齿圈401A和第二齿圈701A的外径比第一太阳轮401和第二太阳轮701大，传递的扭矩大，齿圈与行星轮啮合传动的效率比太阳轮与行星轮啮合传动的效率高，能很好地提高无级变速器的功率传递性能，更适合需要传递较大功率和扭矩的领域应用。
经过试验验证，该实施例将传输扭矩的能力增大40％左右，同时降低了运行时第一行星轮402和第二行星轮702的离心力的危害，同时润滑性能更好，可以满足无级变速器的不同工况的应用。
