Description
Technical field
This utility model relates to the drive mechanism of agricultural machinery, is specially a kind of noiselessness ratchet mechanism.
Background technology
Ratchet mechanism, a kind of one-way intermittent motion mechanism being made up of ratchet and pawl.Ratchet mechanism is commonly used in various machine
In bed and automat in the indexing of index(ing) feed or rotary table, also it is commonly used on jack.Ratchet mechanism in bicycle
For unidirectional drive, in hand winch, ratchet mechanism is conventional in case non-return turn.It is often accompanied by noise and shakes during ratchet mechanism work
Dynamic, therefore its operating frequency can not be too high.
The noise of ratchet mechanism is the reset element using spring to be ratchet due to it, and ratchet slides on ratchet and impacts spine
Wheel produces.Its scope of application of the influence of noise of ratchet mechanism, such as need when indoor use ratchet mechanism low noise or
Noiseless.
Utility model content
This utility model is in order to solve to use spring excessive as ratchet pawl reset part noise, it is intended that provide a kind of low noise
Click drive mechanism.
This utility model offer base case is: noiselessness ratchet mechanism, including frame, ratchet, ratchet and engine
Structure, wherein, also includes crank, slide block, rocker, fork and pin, actuating unit connecting crank, the hinged cunning of free end of crank
Block, rocker has chute, and slide block is positioned in chute and is connected with slide, is rotationally connected with the rotating shaft of frame in the middle part of rocker,
Pawl wheel is connected to the rotating shaft of frame, and one end of fork is rotationally connected with rotating shaft, and pawl rotation is connected to the other end of fork,
Ratchet one end coordinates with ratchet, and the other end of ratchet is positioned between two pins, and pin is fixedly connected on wobble plate.
Operation principle: actuating unit drives crank to rotate, and crank rotarily drives slide block and rotates, slide block drives rocker toward physical pendulum
Dynamic, rocker drives fork reciprocally swinging, and pawl rotation is connected to fork, and one end of ratchet is limited between two pins simultaneously, ratchet
The other end promotes ratchet during fork swings toward a direction, during fork swings toward other direction, and pin
Ratchet can be made to have a swing, and therefore ratchet will not clash into ratchet during rollback.
Compared with prior art, the advantage of this programme is: owing to ratchet promotes after ratchet during rollback by pin
Post is forced away from ratchet, will not as during Spring driving ratchet rollback ratchet lasting with the contacting of ratchet.Use spring as spine
Can beat ratchet under the drive of spring when disengaging the ratchet of ratchet during pawl rollback power, this is the main source of noise.By
The shock of ratchet and ratchet is avoided, so this programme noise during using is less in this programme.
Scheme two: based on scheme preferred, ratchet has hollow hole.Beneficial effect: hollow hole can reduce the weight of ratchet
Amount, reduces the power consumption in transmission.
Scheme three: preferred for scheme two, slide block has side shield.Beneficial effect: avoid slide block to deviate from chute.
Scheme four: preferred for scheme three, is coated with wearing layer in chute.Beneficial effect: increase the service life of chute.
Scheme five: preferred for scheme four, pin is coated with cushion.Beneficial effect: two pins can intermittent and spine
The collision of pawl, arranges cushion and increases the service life of ratchet and pin.
Scheme six: preferred for scheme five, the output shaft side of the being bar axle of ratchet.Beneficial effect: side's bar axle is easy to and other
The square groove of mechanism match and then transmit power.
Accompanying drawing explanation
Fig. 1 is the structural representation of this utility model noiselessness ratchet mechanism embodiment.
Detailed description of the invention
Below by detailed description of the invention, this utility model is described in further detail:
Reference in Figure of description includes: frame 1, crank 2, slide block 3, rocker 4, ratchet 5, ratchet 6, fork 7,
Pin 8, chute 41, hollow hole 51, side's bar axle 52.
Noiselessness ratchet mechanism as shown in Figure 1, including frame 1, ratchet 5, ratchet 6 and motor, wherein, also includes song
Handle 2, slide block 3, rocker 4, fork 7 and pin 8, motor connecting crank 2, the hinged slide block of free end 3 of crank 2, rocker 4 has
Chute 41, slide block 3 is positioned in chute 41 and is slidably connected with chute 41, being rotationally connected with the rotating shaft of frame 1, spine in the middle part of rocker 4
Wheel 5 is rotationally connected with the rotating shaft of frame 1, and one end of fork 7 is rotationally connected with rotating shaft, and ratchet 6 is rotationally connected with another of fork 7
End, ratchet 6 one end coordinates with ratchet 5, and the other end of ratchet 6 is positioned between two pins 8, and pin 8 is fixedly connected on wobble plate.Ratchet
5 have hollow hole 51.Slide block 3 has side shield.It is coated with wearing layer in chute 41.It is coated with cushion on pin 8.Ratchet 5
The output shaft side of being bar axle 52.
Operation principle: actuating unit drives crank 2 to rotate, and crank 2 rotarily drives slide block 3 and rotates, and slide block 3 drives rocker 4
Reciprocally swinging, rocker 4 drives fork 7 reciprocally swinging, and ratchet 6 is rotationally connected with fork 7, and one end of ratchet 6 is limited to two simultaneously
Between pin 8, ratchet 6 other end promotes ratchet 5 during fork 7 swings toward a direction, puts toward other direction at fork 7
During Dong, pin 8 can make ratchet 6 have a swing, and therefore ratchet 6 will not clash into ratchet 5 during rollback.
Ratchet 5 has hollow hole 51.Hollow hole 51 can reduce the weight of ratchet 5, reduces the power consumption in transmission.Slide block
3 have side shield.Slide block 3 is avoided to deviate from chute 41.It is coated with wearing layer in chute 41.Increase the service life of chute 41.Pin
It is coated with cushion on post 8.Two pins 8 can the intermittent collisions with ratchet 6, cushion is set and increases making of ratchet 6 and pin 8
Use the life-span.The output shaft side of the being bar axle 52 of ratchet 5.Side's bar axle 52 is easy to the square groove of the mechanism with other and is matched and then transmit
Power.
