The diameter-variable wheel device with extending means that has eccentric wheel to drive, this kind driving mode can only make certain extending means stretch out or retracts, and all extending meanss are stretched out simultaneously or retracts, do not possess the function that changes the wheel external diameter, can not make extending means keep locking in a certain position simultaneously.A kind of diameter-changing wheel is arranged in addition, is that have in the radial direction tapped hole and the bolt at wheel cooperates, and to change the external diameter of wheel, this kind device Adjustment operation is complicated by the rotation of screw rod.Also have hydraulically powered diameter-changing wheel, expensive, manufacturing process is complicated, uses seldom in engineering reality.
At present, using maximum is that multiple driving wheel group of taking turns the footpath is combined, and changes velocity ratio, the gear of typical mechanism such as multi-speed bicycle etc. by the replacing drive wheel.Although this device is simple and reliable for structure, high expensive, and can not realize stepless change.
Summary of the invention
The object of the present invention is to provide a kind of stepless speed change driver.
The technical solution adopted in the present invention is to comprise wheel seat, screw thread dish, adjusting gear and a plurality of reducing piece; Described a plurality of reducing piece is distributed in wheel seat and is provided with screw thread or tooth, and can do radially to come and go mobile along wheel seat; Described screw thread dish is provided with screw thread radially and meshes screw thread or the tooth of reducing piece; Described screw thread dish also is provided with driving cog, meshes described adjusting gear.The present invention is by the rotation adjusting gear, thereby driving screw thread disc spins moves radially the reducing piece, thereby changes the diameter of drive wheel, realizes the electrodeless reducing of drive wheel, reaches infinite variable speed purpose, and simple in structure, easy to operate, reliable.
Further, described wheel seat is established position-limiting cover, and described screw thread dish places in the position-limiting cover; A plurality of moving jaws are distributed in the position-limiting cover end face and can move radially, the described a plurality of reducing pieces of the corresponding connection of described a plurality of moving jaws.The present invention both had been used for limiting moving direction and the scope of screw thread dish, also was used for limiting moving direction and the scope of moving jaws, was convenient to design and processing, and structure is ingenious rationally.
Further, the adjacent of described a plurality of moving jaws is established a plurality of radiating blocks, and described a plurality of radiating blocks are provided with the screw thread of screw thread or tooth and thread engagement dish, and the cooperation of described radiating block and reducing piece is to radially slide cooperation.The distributing of heat when the present invention is conducive to High Rotation Speed improved the intensity of drive wheel integral body simultaneously, accelerates the working life that dissipation of heat is conducive to improve driving belt or Transmitted chains, the adverse consequences of avoiding high-speed motion to bring; The cooperation of described radiating block and reducing piece is to radially slide to be combined with to be beneficial to assembling and transferring heat energy, reduces simultaneously the impact on bulk strength.
Further, the shape of described reducing piece and/or radiating block is preferably fan-shaped.Beneficial effect of the present invention is to improve to greatest extent the intensity of drive wheel.
Further, the radially screw thread of described screw thread dish is linear diffusion screw thread or Archimedes's screw thread.Beneficial effect of the present invention is to realize the linear stepless speed change.
Further, described wheel seat is provided with spacing end face, is used for limiting reducing piece cylindrical maximum diameter.Beneficial effect of the present invention is to limit the position of reducing piece, and it is simple in structure, for wheel seat increases a kind of additional function.
The present invention can be widely used in various mechanical transmission, and for example the reducing of driving wheel and/or driven wheel all can be realized stepless change.
Description of drawings
Fig. 1 is axle side schematic diagram of the present invention.
Fig. 2 is that master of the present invention looks schematic diagram.
Fig. 3 is cross-sectional schematic of the present invention.
Among the figure, 1. reducing piece, 2. moving jaws, 3. locating cover, 4. screw thread dish, 5. wheel seat, 6. adjusting gear, 7. bearing housing, 8. bearing, 9. radiating block, 10. spacing end face.
Embodiment
Referring to Fig. 1 to Fig. 3, the present invention includes locating cover 3, screw thread dish 4, wheel seat 5, adjusting gear 6 and a plurality of reducing piece 1; A plurality of reducing pieces 1 are distributed in locating cover 3 and are provided with screw thread or tooth, and can do radially to come and go to move along wheel seat 5, and the present embodiment is six reducing pieces 1; Screw thread dish 4 is provided with screw thread radially and meshes screw thread or the tooth of reducing piece 1; Screw thread dish 4 also is provided with driving cog, engagement adjusting gear 6.Bearing housing 7, bearing 8 are used for the installation connection that adjusting gear 6 is connected with wheel seat.The present invention is by rotation adjusting gear 6, thereby driving screw thread disc spins moves radially the reducing piece, thereby changes the diameter of drive wheel, realizes the stepless variable radius of drive wheel, reaches infinite variable speed purpose, and simple in structure, easy to operate, reliable.
Six reducing pieces 1 connect respectively the end face that 2, six moving jaws 2 of six moving jaws are distributed in position-limiting cover 3, and screw thread dish 4 places in the position-limiting cover 3 and can only rotate.Design and processing are convenient in the present invention, and is rational in infrastructure.
The adjacent of six moving jaws 2 is established the screw thread that 9, six radiating blocks 9 of 6 radiating blocks are provided with screw thread or tooth and thread engagement dish 4, and the cooperation of radiating block 9 and reducing piece 1 is to radially slide cooperation, and the present embodiment is that step type slip lotus root is closed.The distributing of heat when the present invention is conducive to High Rotation Speed improved the drive wheel bulk strength, and the quick heat radiating of drive wheel is conducive to improve the working life of driving belt or Transmitted chains, the adverse consequences of avoiding high-speed motion to bring; Being slidingly matched of radiating block and reducing piece is conducive to assembling and transferring heat energy, reduces simultaneously the impact on bulk strength.
