Description
Technical field
The present invention relates to a kind of internal speed changer of bicycle and its manufacturing process.
Background technology
Major part bicycle shift is that the different size of Flywheel fluted disc of outer speed changer, i.e. multi-disc is overlapped into tower at present
Shape, moves the different Flywheel fluted disc of engagement by chain and carrys out speed change, its volume is larger, and chain is easily fallen during shift speed change, and greasy dirt is more, and not
Suitable sealed dustproof makes.
The content of the invention
It is an object of the invention to provide a kind of small size, closed mechanical transmission, it is easy to the speed change of bicycle, for difference
In outer speed changer, this mechanical transmission is referred to as jack internal speed changer.It is a further object of the present invention to provide in a kind of bicycle
Speed changer manufacturing process.
The present invention relates to the internal speed changer of bicycle and its manufacturing process, it is divided into slow shelves, fast shelves, the part of jack shift three close
Composition is closed, by axletree, carrier, positive star-wheel, anti-star-wheel, sun gear, check ring, change ring washer, ratchet, outer shell barrel, dynamic carrier, master is determined
The compositions such as dynamic cylinder, keystone ring and double-sided bowl；Positive star-wheel and anti-star-wheel have bearing to have external gear teeth to be synthetic parts；Determine carrier left end to fix
In axletree, the built-in positive star-wheel in middle part engages anti-star-wheel, and right-hand member is milled with external gear teeth, is also equipped with non-return ring；Left end of sun wheel engagement is anti-
Star-wheel, right-hand member is milled with outer ratchet；Outer shell barrel be ring gear and flower-drum just as and the positive star-wheel of internal messing；Dynamic carrier left end has positive star
Wheel, right-hand member is milled with interior ratchet；Shift snare is rotatable in actuating cylinder left end, and gear shift mechanism is constituted with non-return ring, realizes that jack becomes
Shelves；Actuating cylinder left end groove is equipped with inside and outside ratchet, and right-hand member installs inermis flywheel；When outer power is made by actuating cylinder ratchet through sun gear
It is slow shelves when outer shell barrel is rotated；It is fast shelves when outer power rotates outer shell barrel by actuating cylinder ratchet through dynamic carrier；If inermis
Pawl is engaged, then is neutral gear；Keystone ring and double-sided bowl can be between equalizing feature speed discrepancy.
The present invention it is important that determine the design of carrier and dynamic carrier, jack shift system design, ratchet spine groove design 3,
Be according to power from planetary wheel carrier input gear ring output can accelerate and power from sun gear input gear ring export can slow down, ratchet
Can one-way force applied conventional principle design with ratchet energy engaging power source and ratchet.
1st, as preferred：The described design for determining carrier and dynamic carrier, determining carrier effect has 4, and one is fixed planet
Frame；Two be to change to turn to, and three are used as static sun gear, and four be fixed non-return ring；It is three barrels of construction synthetic parts, bucket to determine carrier
Left end is fixed on axletree, and bucket week and bowl group be dynamic to be connect and 6 square hole grooves are provided with inside and outside outer shell barrel, bucket 3 positive star-wheels is engaged 3 instead
Star-wheel, bucket right-hand member is milled with the external gear teeth as " static sun gear ", and bucket right end is equipped with non-return ring；Dynamic carrier is that twin-tub constructs conjunction
Member, bucket left end is provided with 3 square hole grooves and installs 3 positive star-wheels, and bucket right-hand member inner ring is milled with interior ratchet, bucket right-hand member and keystone ring and bowl
Group is dynamic to be connected to outer shell barrel.
2nd, as preferred：Described jack shift system design, system is by non-return ring, change ring washer, ratchet, spring, active
Cylinder composition；It is action edge before input when outside sprocket wheel timing pin is rotated, jack is then referred to as during counterclockwise, it is unpowered；Become
Ring washer is that steel disc circular groove constructs and is provided with pawl mouthful and non-return keys, and all anti-sides of circular groove are provided with several cracks and cause it to have certain elasticity,
Can micro- expansion set enter actuating cylinder and anti-side can fall into neck, change ring washer is rotated without deviating from；Become 3 pairs of evagination keys of ring washer
It is in sliding or apical grafting state to stop shell fragment with 1 couple of non-return ring, is sliding continuous turn during positive hour hands, stops when counter-clockwise for apical grafting, top
Connecing makes change ring washer just hour hands can only rotate；Shift snare enters the ratchet in actuating cylinder encirclement " recessed " groove and turned with the positive hour hands of actuating cylinder
Dynamic, design jack rotates every 60 degree, and becoming ring washer will be stopped by non-return ring, and besieged ratchet is by according to the pawl mouthful for becoming ring washer setting
Position is ejected a pair, and another pair ratchet will be taken in by change ring washer or two pairs of ratchets are while be incorporated into groove, and ratchet is obtained with ratchet
With automatic clutch, there are 3 grades of conversion in 180 degree；I.e. the system make use of non-return effect to enable the ratchet that jack is rotated different
The principle that pawl mouthful comes in and goes out comes shift, i.e. jack shift, and shift process can be repeated by continuing jack.
3rd, as preferred：Described ratchet spine groove design, ratchet tail is cylindrical to be milled with axis hole, spring impaling fourth shape axle；
2 pairs of spine grooves are milled with inside and outside actuating cylinder left end " recessed " groove, groove tail is cylindrical, column bottom is milled with axis hole, fourth shape axle buckles into column
In mouthful, make pawl spring flexibly difficult for drop-off；Ratchet is upspring as normality, this design uniform force and easy to process.
4th, as preferred：The packaging technology of described internal speed changer, it is characterised in that including following process：
1.1 assembling deceleration parts：
1.11 are inserted in from axletree left end and determine carrier, left nut positioning, then from right-hand member load in bowl group, left inside ring；
