Technical Field

[0001] The utility model relates to the technical field of transmission equipment, in particular to a spiral centrifugal self - transmission. Background Technique

[0002] By changing the size of the rotating disc, the adjustment of the transmission ratio is realized to meet different requirements. In the prior art, during the actual use of the self - transmission, due to the inconvenience of the driving wheel of the generator and the change of the size of the rotating wheel, the transmission belt becomes loose, lacking the function of straightening and adjusting the transmission belt.

[0003] For example, a disclosed authorized patent document with the application number CN202222436949.9, a vehicle transmission bracket with a simple quick - release structure, includes a mounting frame, a mounting plate, a fixed block, a limit card slot and a transmission main body. The inner part of the top end of the mounting frame is a cavity. The mounting plate is installed on the outer surface of the top end of the mounting frame, and limit clamping blocks are symmetrically arranged on the outer surfaces of both sides of the top end of the mounting plate. This vehicle transmission bracket with a simple quick - release structure is provided with a bidirectional threaded rod and limit clamping blocks. During the use of the whole device, through the rotation of the bidirectional threaded rod and the cooperation of the limit sliding block, the limit clamping blocks on both sides of the top end move closer to the middle at the same time, so as to clamp and fix the whole transmission main body. At the same time, the expansion and retraction of the limit clamping blocks can be controlled by controlling the rotation direction of the bidirectional threaded rod, so that the whole device is fast and convenient for disassembly and assembly, and the overall structure is simple and easy to use.

Since the four pulleys on the surface of the force - receiving paddle are located at the top of the four guiding strips, and the four guiding strips are bent and arranged on the inner wall of the rotating cylinder, the rotating cylinder is driven to rotate. The kinetic energy is transmitted to the output disc of the generator through the transmission toothed belt. When the force - receiving paddle rotates faster and faster, under the influence of centrifugal force, the force - receiving paddle and the rotating cylinder move away from each other. The movement of the rotating cylinder will make the transmission toothed belt located at the small annular groove move to the middle annular groove or the large annular groove, and by changing the transmission ratio, the output of the engine is improved. The spring part is mainly used to keep the transmission toothed belt at the smallest annular groove to avoid falling off. As the transmission changes, the transmission toothed belt will be tightened or loosened. At this time, the driving motor is used to drive the threaded rod to rotate, and the threaded rod controls the sliding block to slide in the frame body. The top of the frame body abuts against the toothed disc to mesh with the transmission toothed belt, so as to keep the transmission toothed belt tightened, and solve the problems raised in the above - mentioned background technique.

Since the four pulleys 6 on the surface of the forced paddle 5 are located at the top of the four guide bars 4, wherein the four guide bars 4 are bent and arranged on the inner wall of the rotating drum 1, the rotating drum 1 is driven to rotate, and the kinetic energy is transmitted to the output disk of the generator 32 through the transmission toothed belt 33. When the forced paddle 5 rotates faster and faster, the forced paddle 5 and the rotating drum 1 are moved away from each other due to the centrifugal force, and the movement of the rotating drum 1 causes the transmission toothed belt 33 located at the small annular groove 31 to move to the middle annular groove 32. shaped groove 31, or large annular groove 31, by changing the transmission ratio, the output of the engine is improved, wherein the spring member 7 is mainly used for transmitting the toothed belt 33 at the smallest annular groove 31 to prevent it from falling off, and with the change of transmission, the transmission toothed belt 33 will be tightened or loosened. At this time, the driving motor 305 is used to drive the threaded rod 302 to rotate, and the threaded rod 302 controls the slider 302 to slide in the frame 303, and the top of the frame 303 contacts the toothed disc 301 and engages with the transmission toothed belt 33, thereby keeping the transmission toothed belt 33 tight.

[0032] Specifically, as the transmission changes, the transmission toothed belt 33 will be tightened or loosened. At this time, the driving motor 305 is used to drive the threaded rod 302 to rotate, and the threaded rod 302 controls the slider 302 to slide in the frame 303.

The kinetic energy is transmitted to the output disc of the generator 32 through the transmission toothed belt 33. When the force-receiving paddle 5 rotates faster and faster, under the influence of centrifugal force, the force-receiving paddle 5 moves away from the rotating cylinder 1. The movement of the rotating cylinder 1 causes the transmission toothed belt 33 located at the small annular groove 31 to move to the middle annular groove 31 or the large annular groove 31, improving the output of the engine by changing the transmission ratio. Among them, the spring member 7 is mainly used to keep the transmission toothed belt 33 located at the smallest annular groove 31 to prevent it from falling off. As the transmission changes, the transmission toothed belt 33 will become taut or loose. At this time, the driving motor 305 is used to drive the threaded rod 302 to rotate, and the threaded rod controls the slider 302 to slide within the frame 303. The top of the frame 303 abuts against the toothed disc 301 to engage with the transmission toothed belt 33, thereby keeping the transmission toothed belt 33 taut.
