After changing, different performances can be presented in stepless transmission.
It it can be seen that, is hollow structure inside bucket wheel planet wheel spindle 14, bucket wheel planet wheel spindle 14 and bucket wheel 901 can in Fig. 2
Think the separate structure being fixedly connected, also can be made integral structure, the present embodiment is structure as a whole, and planet wheel spindle 12 passes through sky
The bucket wheel planet wheel spindle 14 of the heart, so that overall structure is very compact, the overall dimension of stepless transmission can be done very
It is small, it is suitble to the application of various occasions；It is equipped with inner chamber body 2 inside outer housing 1, forms a closed cavity, middle casing 101
It is interior to fill appropriate oil liquid, so that the gear engagement rich oil lubrication of inner chamber body 2, can reduce gear wear and noise；
In Fig. 3 it can be seen that, 1 inner wall of outer housing correspond to 901 position of bucket wheel equipped with semi-circular shape cavity, bucket wheel 901
In the cavity of semi-circular shape, bucket wheel 901 is located in 1 inner wall semi-circular shape cavity of outer housing, and hydraulic power, the liquid of bucket wheel 901 are viscous
Power will play more effective performance, realize the compact and optimized of structure, while meeting more excellent performance.
The operational process of the stepless transmission of the embodiment is that upon start up, setting power is defeated clockwise from first axle 3
Enter, the first sun gear 401 is driven to rotate clockwise, the first sun gear 401 drives the first rotation counterclockwise of planetary gear 402, passes through
The planet wheel spindle 12 being fixedly connected drives the rotation of the second planetary gear 702, in the second sun gear 701 by the resistance from the second axis 6
Power, the second planetary gear 702 drive the first support frame 5, the second support frame 8, third branch around the second revolution counterclockwise of sun gear 701
The revolution counterclockwise of support 11 and outer housing 1；First axle 3 rotates clockwise simultaneously, and drive is fixedly connected on the bucket wheel of first axle 3 too
Sun wheel 1001 rotates clockwise, the rotation counterclockwise of bucket wheel planetary gear 1002, and then drives the rotation counterclockwise of bucket wheel 901, bucket wheel 901
In 1 inner wall semi-circular shape cavity of outer housing, the rotation counterclockwise of bucket wheel 901 is formed in middle casing 101 by oil liquid resistance
Torque, this resistance include the revolution of middle casing 101 formed liquid gravity, leave 901 oil liquid of bucket wheel and be injected to adjacent bucket wheel 901
The liquid viscous force of oil liquid between the cavity of 1 inner wall semi-circular shape of hydraulic power and bucket wheel 901 and outer housing, the resistance that bucket wheel 901 is formed
Torque passes to the first support frame 5, the second support frame 8 and third support 11 simultaneously and is formed and prevented by the second planetary gear 702
Because of the torque to revolve caused by 6 resistance of the second axis, and then drive the second planetary gear 702 to 701 stress of the second sun gear, second sun
Wheel 701 drives 6 output power of the second axis, and oil liquid is initially 0 to the resistance of bucket wheel 901, with the increase of 3 speed of first axle, oil
Liquid increases exponentially the resistance of bucket wheel 901, and the second sun gear 701 drives the rotation of the second axis 6, and then dynamic by the output of the second axis 6
Power.
The initial start stage of the above process of the present embodiment 1, stepless transmission is the starting of zero torque of zero-speed, in starting mid-term
When, the resistance fast lifting that bucket wheel group 9 is subject to, resistance finally acts on the first support frame 5, the second support frame 8 and third support
It on frame 11, while acting also on middle casing 101, when input is slow-speed of revolution situation, the resistance that bucket wheel 901 provides is inadequate, defeated
When torque is undesirable out, the first end cover 102 of outer housing 1, second end cover 103 and 101 any end of middle casing are implemented to make
Dynamic control is prevented the revolution of outer housing 1 by braking external force, can reduce and provide the dependence of resistance to bucket wheel 901, increase stepless change
The output torque of fast device, when outer housing 1 is in semi-brake, stepless transmission realizes stepless shift function, when outer housing 1 is made entirely
When dynamic, stepless transmission realizes the function of speed reducer；When declared working condition operates, the speed and moment of torsion of stepless transmission are to steady
Fixed, 901 stress balance not rotation of bucket wheel, mutual gear does not rotate, the whole synchronous transfer for realizing power, levels off to 1:1
Transmission.The above various application forms are flexible, can realize various fields by the way that different input/output terminal and control terminal is arranged
Application configuration.
It is 3 or more that the first planetary gear 402 and the second planetary gear 702 of the series stepless transmission, which can be selected, the reality
It applies in example, the first planetary gear 402 and the second planetary gear 702 are respectively 9, according to the difference for transmitting power and can use size
Difference, the first planetary gear 402 and the second planetary gear 702 of different number are set, to adapt to different application requirements, generally
The different quantity such as 6,9,12 can be selected.
It can further be seen that being fixed with center bucket wheel 13 on first axle 3 or the second axis 6 in Fig. 3, center bucket wheel 13 is located at the
