Description
Technical field
The present invention relates to mechanical transmission mechanism, is a kind of chain drive, more particularly, is a kind of chain of suspended load and sprocket wheel of chain drive-belt of being applicable to.
Background technique
Existing chain is connected to form by some pitch chain joints.The inner plate that chain link is nested with by roller, roller two ends, the outer plate of inner plate arranged outside are formed by bearing pin is hinged.Existing inside and outside carrier bar all is the figure of eight, inside and outside carrier bar can be around the unconfined rotation of bearing pin, when the chain link suspended load of this chain passes through drive chain crop rotation break-in campaign, the chain link that drive sprocket moves the chain forward is subjected to pulling force, oppositely the chain link that moves is subjected to thrust and is in relaxed state, and reversing impact appears in the load that causes chain link plate to hang.With existing chain drive pumping unit is example, existing chain drive pumping unit has chain, chain ring is on the driven sprocket of upper and lower setting, drive sprocket, having the extraordinary chain link that the lengthening bearing pin is used to carry in one end of connecting rod and the chain is connected, the other end of connecting rod then and the tandem-driving bogie that is arranged between fixed guide in the frame hinged, one end of tow rope is connected with tandem-driving bogie, and the other end of tow rope is then walked around head sheave and is connected with the polished rod of well head by rope hanger.When the extraordinary chain link drivening rod of chain makes tandem-driving bogie vertically do straight reciprocating motion, the polished rod of the tow rope tractive well head that is connected with tandem-driving bogie is also done straight reciprocating motion, but, because in the chain link, outer plate all is the figure of eight, in, outer plate does not have constraint, when the extraordinary chain link of suspended load passes through drive chain crop rotation break-in campaign, drive sprocket makes chain be subjected to pulling force by the chain link of drive sprocket back, and the chain link of front is subjected to thrust to be in relaxed state, drive sprocket is in continuous rotation, but extraordinary chain link must wait for oppositely move the chain link tensioner after could continue mobile, reversing impact appears in the load that causes the extraordinary chain link of chain to hang, within the specific limits, the loose degree of drive chain is bigger, the degree of the reversing impact that chain drive pumping unit produces is also bigger, the reversing impact that occurs causes the wearing and tearing between each kinematic pair to be accelerated continuously, undoubtedly, greatly reduce the working life of chain drive pumping unit, increased the repair and maintenance time, influence oil pumping operating efficiency has increased cost of production.
Summary of the invention
The present invention follows a general plotting, is two directly related and cooperatively interact and use a kind of chain and sprocket wheels.Its goal of the invention is, provides a kind of bearing capacity strong, stable drive, and the chain of long service life reversing impact appears, in the load that can avoid chain link to hang; Another purpose of its invention is, provides a kind of and described chain to be used, and flank of tooth intensity height, wear-resisting property are good, and it is convenient to change sprocket, the sprocket wheel of long service life.
Realize that the technological scheme that purpose of the present invention adopts is:
A kind of chain, it comprises some pitch chain joints 20, it is characterized in that: also comprise the extraordinary chain link 21 of some joints, some pitch chain joints 20 are hinged successively with the extraordinary chain link 21 of some joints, the structure of described extraordinary chain link 21 is, comprise roller 7, the two ends of roller 7 are nested with extraordinary inner plate 11, extraordinary inner plate 11 places the groove of extraordinary outer plate 10 interior hinged by bearing pin 1, described extraordinary inner plate 11 exterior edge faces are provided with the inclined-plane of symmetry, described extraordinary outer plate 10 is provided with groove, and 10 liang of end surfaces of extraordinary outer plate are provided with the inclined-plane of symmetry.
In described extraordinary chain link 21, the extraordinary chain link 22 of suspended load is placed in the middle, the structure of the extraordinary chain link 22 of suspended load is, comprise special type have strong market potential the axle 13, be provided with gap at special type axle 13 the end of having strong market potential, be provided with the extraordinary outer plate 23 of inner concave shape in the both sides of opening position, extraordinary inner plate 11 places in the groove of the extraordinary outer plate 23 of inner concave shape respectively and is nested with two ends at roller 7, hinged by short pin shaft 12, the special type axle of having strong market potential 13 is loaded in the axle bed 15, and the special type bolt 16 that axle 13 1 ends install of having strong market potential is connected with short pin shaft 12.
The angle on described extraordinary inner plate 11 exterior edge faces and inclined-plane
