Description

Technical Field

[0001] The invention relates to the field of power devices, and in particular to a wheel capable of realizing radial rotation by end surface force. Background Art

[0002] A power machine is a machine that converts energy such as heat or electricity into mechanical energy. Most existing power machines need to consume a large amount of gasoline or diesel, such as internal combustion engines. Some power machines also emit a large amount of exhaust gas, causing air pollution, or have low mechanical efficiency. The current pneumatic power machine includes a base, on which a self-closing switch assembly or a cylinder is installed. A connecting rod is movably connected to a cam on the piston of the cylinder, a transmission pulley is connected to the convex output shaft, and a high-pressure pipeline is connected between the front end of the piston of the cylinder and the pneumatic chamber of the self-closing switch assembly. This type of pneumatic power machine has the following problems: low energy, uniform power transmission part, and large movement vibration.

[0003] Application number CN201610166227.2 discloses a wheel that can achieve radial rotation by end face force, including a wheel body, and at least one first helical surface and a second helical surface are respectively provided on the two end faces of the wheel body; a transition slope is respectively provided at the head and tail junction of the first and second helical surfaces. A pressure power machine includes a housing, an output shaft, and a wheel. The wheel is arranged on the output shaft, and a front cover and a rear cover are respectively provided on both ends of the housing; a plurality of pressure cylinders are provided on the inner sides of the front and rear covers, and the pressure cylinders are inclined to the axis of the output shaft, and the piston rod heads of the pressure cylinders on both sides are provided with bearings, and the bearings on both sides are in contact with the first and second helical surfaces respectively; the input end of each pressure cylinder is connected to the pressure supply device through the pressure control device and the input pipeline in turn, and the pressure control device can control the closing / opening of the input pipeline. When pressure is applied to the helical surface, the helical surface converts the pressure into rotational force, that is, the rotation of the wheel is realized.

[0004] During the operation of the above-mentioned wheel, after the piston rod moves from the highest position of the spiral surface to the lowest position, it needs to pass through the transition slope to return to the highest position to start the next round of rotation. The existing transition structure is a transition slope with a push block and a mechanically controlled three-way valve. Specifically, during the rotation of the wheel, the push block set at the lowest position of the spiral surface pushes the mechanically controlled three-way valve to close the compressed gas entering the cylinder, and then the transition slope pushes the piston rod that loses the cylinder pressure upward, thereby achieving the transition from the lowest position to the highest position. This transition structure requires the cylinder, mechanically controlled three-way valve, transition slope and push block to cooperate with each other during the transition action. The transition structure is complex and consumes too much energy during the transition, reducing work efficiency. Summary of the invention

[0044] Furthermore, the large helicoid 15 and the small helicoid 19 are both made of smooth wear-resistant metal material. The smooth surface is conducive to reducing rolling friction, which reduces energy loss on the one hand, and can prolong the service life by using wear-resistant metal material on the other hand.

[0045] Furthermore, the large helicoidal surface 15 is composed of several metal blocks, which are fixed by screws.

[0046] Furthermore, the large spiral surface 15 is configured to be in the shape of a truncated cone which is high in the middle and low around.

[0047] Preferably, the rotating wheel 1 is provided with a mounting groove 17 for assembling the transmission assembly 11 adjacent to the step structure 16. The mounting groove 17 is connected from the large helical surface 15 to the small helical surface 19.

[0048] Preferably, the transmission assembly 11 comprises: a lever 12 disposed in the rotating wheel 1 and a pressing block 14 disposed near the step structure 16 of the lever 12 .

[0049] Among them, the lever 12 includes: a rotating end 121 and a movable end 122, the rotating end 121 and the movable end 122 are respectively arranged on the outer surface of the large spiral surface 15 and the outer surface of the small spiral surface 19 through the installation groove 17, the rotating end 121 is connected to the wheel 1 through the rotating support 13, the movable end 122 is arranged on the outer surface of the small spiral surface 19 below the step structure 16, and the rest of the lever 12 is located in the installation groove 17, the pressure block 14 is arranged above the movable end 122 and contacts the movable end 122, and the pressure block 14 moves in the vertical direction through the movable end 122.

[0050] Preferably, the pressing block 14 includes: a pressing block stopper 141 fixedly connected to the mounting groove 17, a pressing block body 142 disposed in the pressing block stopper 141, and a sliding auxiliary member 143 disposed between the pressing block stopper 141 and the pressing block body 142.

The lever 12 is set in the mounting groove 133, and is connected to the strip hole 134 by the rotating shaft 135, so that the lever 12 can be rotated by the rotating shaft 135, and the rotating shaft 135 is set in the strip hole 134, and the lever 12 can also move vertically within the range of the strip hole 134.

[0052] In another embodiment, a protruding structure 123 is further provided on a side between the two ends of the lever 12 and adjacent to the large spiral surface 15, and the protruding structure 123 is used as a fulcrum of the lever 12. By providing the protruding structure 123, the lever arm ratio of the lever 12 can be changed during operation, thereby further saving the energy required to be consumed when the roller passes through the step structure 16.

[0053] Furthermore, a gentle transition surface is provided between the protruding structure 123 and the fixed end of the lever 12 , so that when the roller passes over the lever 12 , the transition is smoother.

[0054] The present invention also includes a method for rotating a wheel that realizes radial rotation by end surface force, comprising the following steps:

[0055] S1. A plurality of rollers are provided on the large spiral surface 15 and the small spiral surface 19 of the runner 1, and pressure is applied to the runner 1 through the rollers;

[0056] S2. The large helical surface 15 of the runner 1 begins to rotate after being subjected to pressure until any roller disposed at one end of the large helical surface 15 moves in a circular motion along the large helical surface 15 to the stepped structure 16;

[0057] S3. At the same time as S2 occurs, the roller disposed on the small helical surface 19 is displaced to the movable end 122 of the lever 12, providing pressure to the movable end 122 of the lever 12, thereby driving the pressure block 14 to displace the roller at the step structure 16 of the large helical surface 15 from the lowest point to the highest point, and the wheel 1 completes one rotation;

[0058] S4. Repeat the steps S2 to S3 to make the wheel 1 continue to rotate.

[0059] In one of the embodiments, when the pressure on the small helical surface 19 is the same as the pressure on the large helical surface 15, the rollers of the small helical surface 19 are arranged at an even number with equal spacing, and the rollers of the large helical surface 15 are arranged at an equal spacing that is twice that of the rollers of the small helical surface 19. The position of the rollers of the large helical surface 15 is fixed, and the rollers at one end of the small helical surface 19 and the rotating wheel 1 make reverse circular motion at the same angular velocity.

[0060] Furthermore, four rollers of the small helical surface 19 are arranged at equal intervals, and eight rollers of the large helical surface 15 are arranged at equal intervals; the pressure on the small helical surface 19 and the pressure on the large helical surface 15 are both 800N, so the pressure output by the roller of each large helical surface 15 is 100N, and the pressure output by the roller of each small helical surface 19 is 200N, wherein the position of the roller of the large helical surface 15 is fixed, and the roller at one end of the small helical surface 19 and the rotating wheel 1 make reverse circular motion at the same angular velocity.

[0061] The number of rollers of the small helical surface 19 is 4 and the angular interval between adjacent rollers is 90°; the number of rollers of the large helical surface 15 is 8 and the angular interval between adjacent rollers is 45°. When the roller on one side of the large helical surface 15 is fixed, the wheel 1 starts to rotate after being subjected to pressure, and the angular velocity of the wheel 1 relative to the rollers arranged on both sides thereof (the large helical surface 15 and the small helical surface 19) is the same. When the wheel 1 rotates 45° relative to the roller of the small helical surface 19, the wheel 1 also rotates 45° relative to the roller of the large helical surface 15. On this basis, the roller of the small helical surface 19 makes reverse circular motion at the same angular velocity, that is, when the roller of the large helical surface 15 rotates 45° relatively, the roller of the small helical surface 19 rotates 90°. This ensures that whenever the roller of the large helical surface 15 is displaced to the step structure 16, the roller of the small helical surface 19 can be displaced to the corresponding position to drive the lever 12 to complete the transition of the roller of the large helical surface 15.

[0062] Furthermore, a protruding structure 123 is provided on one side between the two ends of the lever 12 and adjacent to the large spiral 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 ratio of the force arm between the rollers on the lever 12 can be changed by the movement of the rollers, so that the energy required when the rollers complete the transition at the step structure 16 can be reduced, and the transition process can be made more gentle.

[0063] Example 2

[0064] Reference Figures 11 to 16 , which is different from the above embodiment in that the setting of the pressing block 14 structure in embodiment 1 is cancelled, and the Figure 11 to Figure 13 Among them, the lever 12 includes: a rotating end 121 and a movable end 122, and the rotating end 121 and the movable end 122 are respectively arranged on the outer surface of the large spiral surface 15 and the outer surface of the small spiral surface 19 through the installation groove 17, the rotating end 121 is connected to the spiral disk 1 through the rotating support 13, and the movable end 122 is arranged on the outer surface of the small spiral surface 19 below the step structure 16, and the rest of the lever 12 is located in the installation groove 17, and the lifting end 14 is arranged above the movable end 122, and the lifting end 14 moves in the vertical direction through the movable end 122.

[0065] Combination Figure 14 to Figure 16 Furthermore, a protruding structure 123 is provided on one side adjacent to the large spiral surface 15 between the two ends of the lever 12, 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 ratio of the force arm between the piston rod assemblies 3 on the lever 12 can be changed by the movement of the piston rod assembly 3, so that the energy required when the piston rod assembly 3 completes the transition at the step structure 16 can be reduced, and the transition process can be more relaxed.

[0066] Specifically, the formula for calculating the downward force on the lever is:

[0067] F=[F 总 / (α+β)]*α;

[0068] Where: F is the actual force on the lever, F 总 is the pressure applied by the cylinder, α is the angle between the piston providing downward pressure and the large spiral surface, and β is the angle between the piston providing downward pressure and the lever.

[0069] Combination Fig.17 , the actual pressure F1 of the roller at the end on the lifting end 14 of the lever 12 = F / a*b; the actual pressure F1 of the roller at the end on the rotating end 121 of the lever 12 = F / a*a;

[0070] The above shows and describes the basic principles, main features and advantages of the present invention. It should be understood by those skilled in the art that the present invention is not limited to the above embodiments. The above embodiments and descriptions are only for explaining the principles of the present invention.
