Description
Art
The present invention relates to a kind of power transmission chain, specifically, is related to the power chain suitable for buncher
Bar.
Background technology
Being presently used for the power chain of buncher or band mainly has two kinds, and one kind is pull-type driving-chain, another
It is pushing-type driving-chain.Pull-type driving-chain is that the conical surface that disk is bored by the end face of the connecting pin of chain and the transmission of buncher connects
Touch, pull cone disk passing power；And pushing-type driving-chain is pushing away by the substantially continuous arrangement being installed on flexible steel band
The both sides end face of piece and the taper-face contact of the transmission cone disk of buncher, mutually squeeze between push jack and push jack and push away, so as to promote
Bore disk passing power.Pull-type driving-chain cuts both ways with pushing-type driving-chain, and pull-type driving-chain chain link is durable, not easy to break,
The flexibility of chain is larger, and gearratio is big compared with pushing-type driving-chain, but due to being end face and the buncher of the connecting pin for leaning on chain
Transmission cone disk taper-face contact passing power, and the face area of the connecting pin of chain is small, easily skids, easily because of connecting pin end
The abrasion in face and cause the damage of buncher；And pushing-type driving-chain is due to being basic on flexible steel band by being installed on
The both sides end face of upper continuously arranged push jack and the taper-face contact passing power of the transmission cone disk of buncher, push jack and cone disk
Contact area it is larger, transmission efficiency, be not easy to skid, but flexible steel band fatiguability is broken, and causes the damage of buncher
Bad, in addition, pushing-type driving-chain is unable to overbending, gearratio is small compared with pushing-type driving-chain.
The content of the invention
The defects of in order to overcome the driving-chain of above-mentioned buncher to exist, the present invention provide a kind of compound electrodeless change of pushing block
Fast device driving-chain, the driving-chain combines above two buncher driving-chain a little, so as to overcome buncher
Driving-chain existing for drawbacks described above.
The technical solution adopted for the present invention to solve the technical problems is：A kind of compound buncher driving-chain of pushing block,
Including：Multiple chain links (5) and the chain pin (4) of the multiple chain links (5) of connection, it is characterized in that：Chain link (5) by chain nodal plate group (18) with
And formed with the pushing block (3) of chain nodal plate group (18) integrated setting, in described adjacent with front end in the preceding surface of the pushing block (3)
Pushing block (3) forms contact site, the passing power under the squeezing-pushing action of chain link (5).
The pushing block (3) is located at the upper end of chain nodal plate group (18)；Or pushing block (3) is divided into pushing block (15) and lower pushing block
(16) top and bottom of chain nodal plate group (18), are respectively arranged on.Upper and lower pushing block contacts with cone disk jointly, and contact area is big, increase
Frictional force between driving-chain and cone disk, improves transmission effect, and make the stress more balanced and reasonable of driving-chain.
Pushing block lock (6) is provided between the adjacent pushing block (3).Described pushing block lock (6), in pushing block (3)
Preceding surface is provided with pushing block lock pin (7), and pushing block lock buckling groove (8), two adjacent pushing blocks (3) are provided with the rear surface of pushing block (3)
The pushing block lock pin (7) and the pushing block lock buckling groove (8) of front end pushing block of rear end pushing block interlock, and two pushing blocks to interlock latch (6)
The upper and lower end face of pushing block lock pin (7) and pushing block lock buckling groove (8) is pushing block lock pin upper surface (11), pushing block lock buckling groove upper surface
(13) and pushing block lock pin lower surface (12), pushing block lock buckling groove lower surface (14) are that the pushing block to be interlocked with this latches (6) place
Two chain links (5) between chain pin (4) be rotating shaft arc surface；The length of pushing block lock pin (7) is worked in driving-chain
It is in journey in the state of maximum flexion, pushing block lock pin (7) is still in pushing block lock buckling groove (8).The work of pushing block lock (6)
With the longitudinal stability for being to maintain driving-chain, make driving-chain that shake is reduced or eliminated in transmission process.
The beneficial effects of the invention are as follows：The buncher driving-chain is connected with chain link, and the flexibility of chain is larger, transmission
Than big, and it is durable, avoid traditional pushing-type driving-chain flexible steel band connection easy fracture, and the disadvantage that flexibility is limited
End；The driving-chain is the taper-face contact passing power of the transmission cone disk by driving-chain pushing block both sides end face and buncher,
Pushing block and the contact area for boring disk are larger, transmission efficiency, are not easy to skid, and overcome the company that traditional pull-type driving-chain leans on chain
The end face of pin and the taper-face contact passing power of the transmission cone disk of buncher, contact area is small, easily skids, and connect
The defects of selling end face damage easy to wear.In addition, the driving-chain chain link uses pushing block design up and down, make driving-chain and cone disk contact surface
Product is big, improves transmission effect, and make the stress more balanced and reasonable of driving-chain；Driving-chain adds pushing block lock, makes transmission
The stability enhancing of the vertical and horizontal of chain, be advantageous to driving-chain reduces or eliminates shake in transmission process；Pushing block point is wide to be pushed away
Block and narrow pushing block, the contact surface for making driving-chain and cone disk is in dentation, increase driving-chain and the grasp for boring panel surface, saves material
Material, manufacturing cost is reduced, further, since narrow pushing block size is smaller, makes driving-chain weight saving, reduces energy consumption；Pushing block with
The contact surface of cone disk is provided with anti-slip veins, improves pushing block cone disk contact surface with boring panel surface grasp and breaking up cone panel surface
The ability of oil film, anti-skidding and good heat dissipation effect.The driving-chain designs the transmission efficiency for being effectively improved driving-chain, reduces energy
Consumption, has saved manufacturing cost, has reduced the fault rate of buncher.
