As shown in Figure 1, Figure 2 and shown in Fig. 5；
Rotary booster engine structure of the present invention, it includes that the transmission shaft 2 being arranged on support element 1 and driving transmission shaft 2 rotate
Driving device 3 is threadedly coupled a sliding block 5 on the transmission shaft 2；The support element 1 is equipped with an axis and transmission shaft 2
The parallel energy-storage travelling wave tube 4 of axis, one end of the energy-storage travelling wave tube 4 are connect with support element 1, the other end and the sliding block 5 of energy-storage travelling wave tube 4
Connection, the energy-storage travelling wave tube 4 is used to apply thrust to sliding block 5, and provides the power-assisted that transmission shaft 2 rotates by sliding block 5.This turn
At work, driving device 3 drives transmission shaft 2 to rotate to dynamic servomechanism, since sliding block 5 is threadedly coupled with transmission shaft 2, and sliding block
5 connect with energy-storage travelling wave tube 4, therefore sliding block 5 is moved with the rotation of transmission shaft 2 along 2 length direction of transmission shaft；Due to energy storage member
Part 4 is used to apply uniform thrust to sliding block 5, and provides the power-assisted that transmission shaft 2 rotates by sliding block 5, stated differently, since sliding
Block 5 is threadedly coupled with transmission shaft 2, and when sliding block 5 is by the thrust consistent with 2 axial direction of transmission shaft, sliding block 5 can turn transmission shaft 2
It is dynamic that certain tangential force is provided, provide power-assisted for the rotation of transmission shaft 2；In order to make it easy to understand, assuming that sliding block connects with transmission shaft spiral
Frictional resistance when connecing is zero, then when sliding block is moved along propeller shaft length direction, and since the screw thread of sliding block and transmission shaft connects
Connect relationship, sliding block then drives transmission shaft to rotate, as a same reason, in normal state, sliding block by with transmission shafts to consistent
When elastic force or thrust, energy-storage travelling wave tube can provide certain tangential force by sliding block to the rotation of transmission shaft, be carried for transmission shaft rotation
For power-assisted.Therefore driving device is very laborsaving when driving the rotation of transmission shaft single direction, when which rotates
Namely energy-storage travelling wave tube, when being in elastic unfolded state, the rotary booster engine structure manufacturing cost is low, simple in structure.The energy storage member
Part is the product of prior art mature technology, such as gas spring, linear oil cylinder, cylinder, hydraulic cylinder or other constant force energy storage components
