Abstract
The utility model relates to a speed reducer for an axis chain-driving booster of a bicycle, belonging to a speed reducer for a middle axis sustention chain driving booster bicycle. The speed reducer for a booster is composed of a crank axis for a gasoline engine, a driving gear, centrifugal clutch, a plastic driven gear, a three-teeth helical gear shaft, a helical gear, a bonder, a spline sleeve, a middle axis, an elastic axis coupling, a chain wheel, a light flying overrunning clutch, etc. When the utility model is used, the goals of large sped reduction ratio, smooth transmission, low noise and high reliability. Furthermore, the structure is the booster is simple. The utility model is suitable for middle axle middle axis suspension booster bicycle.
Description
The utility model bicycle middle shaft chain-driving servo-unit speed reduction gearing belongs to bicycle middle shaft suspension type chain-driving servo-unit speed reduction gearing.
Existing bicycle middle shaft chain-driving servo-unit speed reduction gearing is secondary or three grades of decelerations, adopt the transmission of steel part straight gear, though also can play transmission of power and deceleration effort, the reduction ratio of speed reduction gearing is little, and gear transmission noises is big, fragile gear, poor reliability, in addition, the complex structure of speed reduction gearing, volume is big, Heavy Weight.These defectives can not satisfy the demand of people to morpet, have influenced the development of morpet and apply.
The utility model bicycle middle shaft chain-driving servo-unit speed reduction gearing provides a kind of transmission of power and deceleration form of renewal, defective and deficiency that existing bicycle middle shaft chain-driving servo-unit speed reduction gearing exists have been overcome, it is big to make it reach reduction ratio, simple in structure, gear is not fragile, stable drive, volume is little, in light weight, noise is low, the purpose that reliability is high.
In order to realize above-mentioned purpose, the technical scheme of utility model bicycle middle shaft chain-driving servo-unit speed reduction gearing is as follows:
Bicycle middle shaft chain-driving servo-unit speed reduction gearing flies overriding clutch etc. by bent axle, driving gear, centrifugal clutch, plastics ring gear, three tooth helical gear shafts, zygote, axis, spline housing, elastic coupling, sprocket wheel, the light of spark ignition engine and constitutes.Driving gear and centrifugal clutch fix, driving gear, centrifugal clutch includes a star-wheel respectively, and star-wheel all is socketed on the gasoline engine crank, driving gear and the engagement of plastics ring gear, plastics ring gear adapter sleeve is connected on the three tooth helical gear shafts, three tooth helical wheels on the three tooth helical gear shafts are meshed with helical wheel top, helical wheel middle part endoporus sky is enclosed within on the spline housing, spline housing is socketed on the axis, zygote is connected with the spline form with spline housing, and can be on spline housing longitudinal travel, zygote and helical wheel are link joint, and an end of elastic coupling and spline housing joins, and links to each other with sprocket wheel, sprocket wheel links to each other with the outer ring that light flies overriding clutch, and light flies the inner ring of overriding clutch and an end of axis socket-connects.
The utility model bicycle middle shaft chain-driving servo-unit speed reduction gearing is compared with existing servo-unit speed reduction gearing, has following characteristics:
The servo-unit volume is little, and is in light weight, simple in structure, stable drive, and reduction ratio is big, especially greatly reduces the rotational noise of gear, and has improved the reliability of chain-driving servo-unit work.
Accompanying drawing is a bicycle middle shaft chain-driving servo-unit speed reduction gearing drive mechanism scheme drawing
Below in conjunction with the embodiment accompanying drawing this application patented technology being done one specifically sets forth
Bicycle middle shaft chain-driving servo-unit speed reduction gearing flies overriding clutch 12 etc. by gasoline engine crank 1, driving gear 3, centrifugal clutch 4, plastics ring gear 2, three tooth helical gear shafts 5, helical wheel 8, zygote 9, axis 6, spline housing 7, elastic coupling 10, sprocket wheel 11, light and constitutes.Driving gear 3 fixes with centrifugal clutch 4, the star-wheel of the star-wheel of driving gear 3 and centrifugal clutch 4 all is socketed on the bent axle 1 of spark ignition engine, driving gear 3 and 2 engagements of plastics ring gear, plastics ring gear 2 adapter sleeves are connected on the three tooth helical gear shafts 5, three tooth helical wheels on the three tooth helical gear shafts 5 are meshed with helical wheel 8 tops, helical wheel 8 middle part endoporus skies are enclosed within on the spline housing 7, spline housing 7 is socketed on again on the axis 6, zygote 9 is connected with the spline form with spline housing 7, and can be on spline housing 7 longitudinal travel, zygote 9 is a link joint with helical wheel 8, elastic coupling 10 links to each other with an end of spline housing 7, and join with sprocket wheel 11, sprocket wheel 11 joins with the outer ring that light flies overriding clutch 12, and light flies the inner ring of overriding clutch 12 and an end of axis 6 socket-connects.
This device can realize that foot-on, motor-driven driving and manpower drive three kinds of mode of operations, is a total mode that realizes utility model, now mode of operation is described below respectively:
One, foot-on mode of operation
Pin is stepped on power and is driven its outer ring by axis 6 by the inner ring that light flies overriding clutch 12, drive sprocket wheel 11 by its outer ring again, sprocket wheel 11 drives spline housing 7 by elastic coupling 10, spline housing 7 drives zygote 9 and helical wheel 8, helical wheel 8 drives three tooth helical gear shafts 5 and plastics ring gear 2 rotates together, plastics ring gear 2 drives driving gear 3, and driving gear 3 drives gasoline engine crank 1 again and rotates, and has realized the foot-on of servo-unit.
Two, motor-driven driving mode of operation
Three, manpower drives mode of operation
Foot-operated power drives its outer ring by axis 6 by the inner ring that light flies overriding clutch 12, drive sprocket wheel 11 by its outer ring again, sprocket wheel 11 drives bicycle rear by chain, simultaneously, sprocket wheel 11 drives elastic coupling 10, elastic coupling 10 drives spline housing 7 and dallies in helical wheel 8 middle part endoporus, and helical wheel 8 is in unbound state with zygote 9, has realized the manpower driving.
