Further, the intermediate pressure output assembly 4 is the second pressure output member 41 .

Preferably, the end pressure output assembly 5 and the intermediate pressure output assembly 4 can use pressure sources such as air pressure and hydraulic pressure.

Further, in this embodiment, air pressure is used as the pressure source for energy saving and environmental protection, and pressure is input into the device through the outside world.

Further, the first pressure output member 51 and the second pressure output member 41 are preferably cylinders, and the cylinder is provided with several pressure chambers, and each pressure chamber is correspondingly provided with a piston rod assembly 3; The number of the second pressure chambers 411 is an even number, and the number of the first pressure chambers 511 disposed on the end pressure output assembly 5 is twice the number of the second pressure chambers 411 . The pressure is input into the cylinder through the valve 53, and then the input pressure is transmitted to each cylinder through the pressure channel 211 to ensure that the output pressure of each cylinder is the same.

For example, there are four second pressure chambers 411 and the piston rod assembly 3 on the intermediate pressure output assembly 4 at equal intervals, and eight first pressure chambers 511 on the end pressure output assembly 5 and the piston rod assembly 3 at equal intervals; The pressure level output by the cylinder is 800N, then the pressure on the small helical surface 19 and the pressure on the large helical surface 15 are both 800N, so each pressure chamber in the end pressure output assembly 5 and the piston rod assembly 3 are in each The output pressure on the large helical surface 15 is 100N; for the same reason, the output pressure of the piston rod assembly 3 on the intermediate pressure output assembly 4 on each small helical surface 19 is 200N, wherein the end pressure output assembly 5 is fixed in Therefore, the position of the piston rod assembly 3 on the large helical surface 15 is fixed, and the intermediate pressure output assembly 4 is fixedly connected with the rotating shaft, so the piston rod assembly 3 on one end of the small helical surface 19 and the helical disk 1 are reversed at the same angular velocity. sports.

Among them, the piston rod assemblies 3 on the intermediate pressure output member 51 are equally spaced to four, and the angular interval between adjacent piston rod assemblies 3 is 90°; the piston rod assemblies 3 on the end pressure output assembly 5 are equally spaced There are 8 sets, and the angular interval between the adjacent piston rod assemblies 3 is 45°. Under the condition that the end pressure output assembly 5 is fixed to the outside world, the helical disk 1 starts to rotate after being subjected to pressure, then the helical disk 1 is opposite to the piston rod assemblies arranged on both sides (the large helical surface 15 and the small helical surface 19 ). The angular velocity of 3 is the same. When the helical disk 1 rotates 45° relative to the piston rod assembly 3 of the small helical surface 19, the helical disk 1 also rotates 45° relative to the piston rod assembly 3 of the large helical surface 15. On this basis, the intermediate pressure The piston rod assembly 3 on the output member 51 makes a reverse circular motion at the same angular velocity, that is, when the piston rod assembly 3 of the large helical surface 15 rotates 45° relative to it, the piston rod assembly 3 of the small helical surface 19 rotates 90°, so that It is ensured that whenever the piston rod assembly 3 of the large helical surface 15 is displaced to the stepped structure 16, the piston rod assembly 3 of the small helical surface 19 can be displaced to the corresponding position to drive the lever 12, and the piston rod assembly 3 of the large helical surface 15 is completed. Transition.

Referring to FIGS. 9 to 11 , a protruding structure 123 is further provided between the two ends of the lever 12 adjacent to the large helical surface 15 , and the protruding structure 123 is used as a fulcrum of the lever 12 . According to the principle of the lever 12, it can be known that the movement of the piston rod assembly 3 changes the ratio of the lever arm between the piston rod assemblies 3 on the lever 12, so that when the piston rod assembly 3 completes the transition at the stepped structure 16, the required amount of time can be reduced. energy, and achieve a more moderate effect of the transition process.

As shown in FIG. 17 , the piston rod assembly 3 includes: a piston rod main body 31 connected to the pressure chamber and a roller 32 arranged on the piston rod main body 31 , through which the piston rod assembly 3 performs circular motion on the large helical surface 15 .

Further, the piston rod assembly 3 further includes: a piston 33 arranged at the top of the piston rod main body 31 and a piston rod return spring 34 arranged below the piston 33; the piston 33 is arranged in the pressure chamber, between the piston 33 and the piston rod main body 31 A piston rod return spring 34 is provided between the protruding parts, and a guide sleeve 35 is also provided at the protruding part of the piston rod of the pressure chamber, and the guide sleeve 35 is used to limit the movement angle of the piston rod main body 31 .

Preferably, the large helical surface 15 is set in the shape of a cone with a high center and a low periphery, and the rollers 32 are set corresponding to the large helical surface 15 in a conical shape with a high outer side and a low inner side.

Further, the piston rod assembly 3 and the pressure chamber are both inclined, and the inclination direction is a direction that is conducive to the movement of the piston rod assembly 3 to the lever 12 and can better apply pressure to the lever 12 . The actual pressure of the piston rod assembly 3 to the lever 12 is adjusted by tilting the pressure output direction of the piston rod assembly 3 .

Further, the piston rod assembly disposed on the large helical surface 15 is inclined between the large helical surface 15 ; the piston rod assembly disposed on the small helical surface 19 is perpendicular to the small helical surface 19 .

22 and 23, when the roller 32 moves to the lever 12, an included angle will be formed between the roller 32 itself, the lever 12 and the large helical surface 15, forming a small lever structure. Therefore, the lever 12 is actually The pressure is different from the pressure provided by the cylinder. Part of the pressure provided by the cylinder is applied to the lever as a downward pressure, and the other part is applied to the large helical surface 15 so that the roller can obtain the driving force for rotation.

Specifically, the formula for calculating the downforce on the lever is:

F=[ _Ftotal /(α+β)]*α;

Among them: F is the actual force on the lever, F is _always the pressure exerted by the cylinder, α is the angle formed between the piston providing downforce and the large helical surface, and β is the angle formed by the piston providing downforce and the lever.

22 , the actual pressure F ₁ =F/a*b of the roller at the end to the raised end 14 of the lever 12 ; the actual pressure F ₁ of the roller at the end to the rotating end 121 of the lever 12 =F/a*a ;

More specifically, referring to FIG. 23, the measured data for the 8 positions of the roller 32 at the movement of the lever 12 can prove that in actual work, the pressure provided by the roller at the end of the large helical surface 15 is greater than that applied by the intermediate rollers A and B. The pressure on the lever; and the pressure exerted by the end roller on the rotating end 121 is less than the pressure exerted by the middle roller A on the rotating end 121, in the case where the end roller and the middle roller A cooperate to press down, so that The lift end 14 obtains the force to lift the lowest roller.

When the piston assembly runs to the position shown in Figure 9, it is the step number 1 recorded in Figure 23; when the piston assembly runs to the position shown in Figure 10, it is the step number 4 recorded in Figure 23; When the position shown in FIG. 9 is the step number 7 shown in FIG. 23 .

Example 2

As shown in FIG. 19 , the difference from the above-mentioned embodiment is that the pressure power machine rotates 180° on the main shaft assembly 2 with the end face of the intermediate pressure output assembly 4 away from the piston rod assembly 3 as the center of rotation to set another pressure of the same structure power machine.

Further, the two intermediate pressure output assemblies 4 are fixed to each other by bolts, and the pressure chambers of the two intermediate pressure output assemblies 4 are staggered from each other. In this embodiment, without changing the structure of the device, the power output energy can be improved directly by simple superposition, and has no influence on the operation of the device at all.

Further, when the number of pressure chambers on the intermediate pressure output assembly 4 is set to four, the relative position of the pressure chambers of one intermediate pressure output assembly is set between two adjacent pressure chambers of the other intermediate pressure output assembly. By staggering the pressure chambers of different intermediate pressure output assemblies, they can be more stable in working state.

Furthermore, the relative positions of the levers provided on the different end output assemblies are arranged diagonally.

Further, referring to FIG. 20 , the main shaft main body 21 in the main shaft assembly 2 extends correspondingly and provides through holes 212 at corresponding positions.

Referring to FIG. 21 , an oil pump 25 is provided at the end of the main shaft body 21 away from the gear set 22 , and the oil pump 25 is arranged between the end pressure output assembly 5 at the end away from the gear set 22 and the helical disk 1 .

In one of the embodiments, the end pressure output assembly 5 is provided with 8 pressure chambers, the two end pressure output assemblies are 16 pressure chambers; the intermediate pressure output assembly 4 is provided with 4 chambers, two intermediate pressure The output assembly provides 8 cavities.

Referring to Figures 24 and 25, when the end pressure output assembly at one end works to the position shown in Figure 24, the end pressure output assembly at the other end works to the position shown in Figure 25.

Referring to FIG. 24 , when the 3 piston rod assemblies X whose one end is arranged at the end pressure output assembly runs to the lever, the 3 piston rod assemblies X are located at the lever 12 and the step because they are on the lever 12 or after passing through the lever 12 At the platform in between, the large helical surface 15 is relatively gentle at the platform, so the above-mentioned three piston rod assemblies X do not provide the force for the rotation of the helical disk 1, and there is a piston rod in the middle pressure output assembly 4 of this end. Component Z moves to the lever at this end and loses power consumption;

Referring to Fig. 25, there are two piston rod assemblies Y at the platform at the other end, so the above three piston rod assemblies (Y, Z) do not provide the force for the rotation of the screw disk.

Further, the pitch of the large helical surface 15 is set to 37.8299, and the pitch of the small helical surface 19 is set to 7.2.

Further, it can be seen from the above-mentioned embodiments that the actual power generated by the power output assembly at the end is: there are 16 pressure chambers at both ends of the power generation. Referring to FIG. 24 , there are 5 actual working pressure chambers on the large helical surface 15 at one end;

Referring to Figure 25, when the lever 12 at the other end of the end pressure output assembly returns to the position of the large helical surface 15, the actual 6 pressure chambers work;

Therefore, the two end pressure output assemblies work in a total of 11 pressure chambers, and the pitch of the large helical surface is 37.8299. So the actual power generated is: 11 pressure chambers multiplied by the pitch 37.8299 equals 416.1289.

(The calculation formula is as follows: 11*37.8299=416.1289).

Further, the power consumption is: two intermediate pressure output components have a total of 8 pressure chambers, of which only 3 pressure chambers are working at the lift end of the lever, and a total of 7 pressure chambers at the left and right ends are working.

Because the screw disk turns left and the intermediate pressure output assembly turns right, two 7.2075mm helix angles are consumed at the same time, 7.2075+7.2075=14.415, and because the area of the intermediate pressure cylinder is twice the area of the end cylinder, the actual power consumption As: 7 times 2 equals 14. 14 times 14.415 equals 201.81.

(The calculation formula is as follows: 14*14.415=201.81).

In summary, it can be known that when the end pressure output component is set with 16 pressure chambers, and the intermediate pressure output component is set with 8 pressure chambers, the actual output power is:

416.1289 (power generated) - 201.81 (power consumption) = 214.3189 (actual output power).

214.3189 (actual output power)/37.8299 (large helical pitch)=5.663 (effective working pressure chamber).

To sum up: the final 5.663 cylinders work effectively on the helix with a pitch of 37.8299 and output power.

The present invention also includes a method for operating a pressure power machine, comprising the following steps:
