Description
Technical field
The present invention relates to agricultural machinery transmission technical fields more particularly to a kind of agricultural operation equipment upper tooth down formula clutch to fill
The design application set.
Background technique
Agricultural operation equipment is common agricultural machinery, common agricultural machine have seeder, fertilizer applicator or and other
The compound operation machine etc. of function combination is same or similar more set operation parts between row and row including a kind of function, more
The different type operation part of kind function；Each place difference agriculture requirement often has working rig to the requirement of agricultural machinery particularity
The problem of selection between the function of tool, between row and row, between agricultural machinery and implement and power source, i.e., whether each component works；Machine
Device system generallys use arrangement of clutch, determines the transmitting or cutting of a certain component associated drive.
Usually machinery such as automobile, tractor, the clutch used have the types such as frictional, hydraulic type, often and gearbox
Etc. mechanisms be used cooperatively；The arrangement of clutch that the present invention studies is tooth down formula, this be the agricultural operations machinery such as seeder commonly use from
It attaches together and sets, realize the handover operation that machine system power transmission is separated and engaged；Good design requirement structure is simple, arrangement of clutch
Separation or bonding station state it is determining with it is reliable, cannot it is smudgy, slide it is unreliable.
In order to which clutch device sets function with fixed bit, in prior art, one is push down steel ball, steel using spring
Ball is resisted against in indent hole subsidiary on control crank, and needs of shifting one's position firmly pull handle and spring pressure and steel ball is overcome to rub
Power is wiped, and ensures original position not malleable；Another kind is moved in limiting slot using rotation reach or handle grip bracing wire
The modes such as dynamic, control arrangement of clutch holddown spring length and position, carry out fixedly separated or engagement location status；These modes
And structure, there are the shortcomings such as structure is complicated, bulk is big, manufacturing cost is high.
Whether there are more simple and reliable clutch mode and structure, is research direction of the invention；The present invention uses new
Conception devises new simple applicable mechanical clutch means.
Summary of the invention
One machine system is frequently necessary to cut off or transmit power and the transmission of machine, needs using arrangement of clutch；This
Invention provides a kind of simple and reliable mechanical clutch means using freedom degree positioning principle from theory of mechanics angle；Pass through device
Inner body effect and mutual cooperation, allow control crank to move in track groove, realize the separation and engagement of arrangement of clutch, and right
Different location achievees the effect that fixed, effective power for implementing cutting or transmitting machine system and transmission.
The present invention provides a kind of mechanical clutch means, by shaft 1, bracket 2, track plates 3, control crank 4, shift fork 5, annulus
6, tooth down sliding sleeve 7, tooth down lid 8, sprocket wheel 9, bearing plate 10, bearing A 11, bearing B 12 are formed.
Shaft 1 is on the whole in the long stick of orthohexagonal, and end is machined with the shape and structure of cylindrical shaft end；End passes through axis
It holds A 11 and assembles sprocket wheel 9, bearing A 11 is axially fixed in 1 end of shaft by screw and bearing plate 10；Orthohexagonal
On shaft part, it is combined with 7 inner hole of tooth down sliding sleeve, tooth down sliding sleeve 7 can move axially in shaft 1；9 end face of sprocket wheel is solid by screw
Determine tooth down lid 8, bearing A 11 is assembled between sprocket wheel 9 and tooth down lid 8, bearing A 11 and sprocket wheel 9 are axially fixed in together
1 end of shaft.
Tooth down sliding sleeve 7 and tooth down lid 8 are designed with three tooth down steps, can be mutually twisted and engage；Tooth down engages handle
Power on sprocket wheel 9 is transmitted on other associated parts of shaft 1 and machine system；Tooth down sliding sleeve 7 can axially move in shaft 1
After dynamic certain distance, it is engaged tooth down step originally and is kept completely separate；The separation of tooth down is that power transmission is in dissengaged positions, sprocket wheel 9
It dallies in shaft 1, shaft 1 does not turn.
Bearing B 12 is assembled with circlip by axis on tooth down sliding sleeve 7, bearing B 12 is assembled in circle by hole card spring
Inside 6 inner hole of ring；Annulus 6 can move axially in shaft 1 together with tooth down sliding sleeve 7；Since bearing B 12 is acted on, tooth down is sliding
Set 7 and shaft 1 can rotate inside 6 inner hole of annulus together.
Socket cap screw is installed at symmetrical holes on 5 lower end of shift fork, two plug, two socket caps is allowed symmetrically to be stuck in
In the external peripheral surface annular groove of annulus 6；At interstitial hole, it is mounted on bracket 2 by straight pin；Shift fork 5 can be with interstitial hole
It is swung centered on the hole of bracket 2, along 1 axial direction of shaft, to drive annulus 6, tooth down by socket cap screw
Sliding sleeve 7 moves axially in shaft 1.
Control crank 4 is mounted at the most upper hole of fork 5 by straight pin, and 4 lower end of control crank, two plane clips the top of shift fork 5
End；There is double assembly relation herein: first is that plane restriction relationship between control crank 4 and shift fork 5, can allow control crank 4 to be pulled
Dynamic shift fork 5, it is final that tooth down sliding sleeve 7 is driven to move along 1 axial direction of shaft, realize the engagement or separation of tooth down step；Two
It is that can allow by the circumferential confinement relationship of straight pin the control crank 4 to be between control crank 4 and shift fork 5 with the most upper hole of shift fork 5
Center is realized and is swung along the vertical direction of 1 axis of shaft.
The rod end of control crank 4 is through in the guide-track groove of guide-rail plate 3, and guide-track groove is by both ends perpendicular to 1 axis of shaft
Vertical channel be connected with the axial groove that interlude is parallel to axis made of Z-type track；When manually pulling control crank 4 in
Between section axial groove it is mobile when, handle plane pulls shift fork 5, and annulus 6, tooth down sliding sleeve 7 is driven to move axially in shaft 1, realizes
Tooth down is engaged or is separated, powerdriven transmitting or cutting between sprocket wheel 9 and shaft 1 between tooth down sliding sleeve 7 and tooth down lid 8；When
When control crank 4 is pulled groove location vertical to both ends, i.e., power transmission separates or is joined to whole design size states, at this time
Control crank 4,5 heeling condition of shift fork are acted on by self gravitation effect and mutual force, handle and shift fork keep plane restriction and
Positional relationship；Handlebar is pulled again and swings to least significant end along vertical channel, and during this, control crank 4 is only around straight pin
Circle swing effect, plane restriction it is unaffected and continue keep before tooth down engagement or discrete state, handlebar exist
The least significant end of vertical channel is maintained under self gravitation effect, it is ensured that 4 position of control crank is fixed, to allow the engagement of arrangement of clutch
Or discrete state remains unchanged under no external force；Until next manual operation changes engagement or the separation shape of arrangement of clutch
State.
Implementation through the embodiment of the present invention has reached following the utility model has the advantages that first is that the double freedom of clutch control crank
Effect of contraction is spent, is skillfully constructed, it is novel in design；Two are that of avoiding the labyrinth pattern of usual manner, and structure of the invention simplifies；
Third is that adapting to agricultural machinery feature, enforceable technical solution of the present invention is provided.
