Description
[technical field]
The utility model relates to a kind of field of mechanical technique, particularly a kind of structure of cage winch.
[background technology]
Cage stranding machine improves the stranded quality of twisted wire owing in stranded process, can make the single line back twist, thereby significantly reduce the torsional deflection of single line in stranded process.The strand basket structure form of cage winch generally is that drum places pay off rack, and pay off rack then is supported between the capstan winch.When stranded, pay off rack is simultaneously around the rotation of capstan winch center, to finish stranded motion, one side is rotated around the axis of self again simultaneously, realize the back twist campaign of single line, because wiring dish in the pay off rack, make that its rotation circle and revolution circle size are bigger, and the restriction of drum size and motion requirement make that whole strand cage size is huge, and make its structure more complicated, simultaneously, the huge centrifugal intertia force that the drum of decoration line and pay off rack are produced around the rotation of capstan winch center the time had both limited the raising of the rotating speed of strand cage, and the while has also proposed very high requirement to the reliability of the supporting construction of pay off rack in the strand cage.
In the strand cage of old structure cage winch, the supporting way of pay off rack in the strand cage seen Fig. 1.It comprises places pay off rack 2 between first capstan winch 1, pay off rack 2, second capstan winch 4, drum 3, back twist ring 5, back twist crank 6, the first capstan winches 1, the second capstan winch 4, place drum 3 on the described pay off rack 2.Usually, between per two capstan winches, generally be uniform six pay off racks in the cage winch, the equal boring in the two ends of pay off rack 2 has through hole.The location of pay off rack 2 left ends, after being little short step location with flange shaft 7 right-hand members, firm with four bolts, flange shaft 7 itself is then leaned in the halving hole of bearings on first capstan winch 1, and described flange shaft 7 left ends also are connected with described back twist crank 6, back twist ring 5 successively; And the right-hand member of pay off rack 2 then connects firmly with minor axis 8, and minor axis 8 also is by in the halving hole of bearings on second capstan winch 4, and like this, the pay off rack 2 in the strand cage has just obtained support.Connect firmly together flange shaft 7, pay off rack 2, minor axis 8, not only to transmit the back twist campaign, but also the huge centrifugal intertia force of being given birth to will bear 2 rotations of drum 3 and pay off rack the time, consequent flexural deformation, can make the friction increase of hole inwall on the capstan winch and axle and bearing, finally cause the support inefficacy and cause overhaul, simultaneously, four fastening bolts of flange shaft 7 right-hand members, owing to be subjected to the alternate stress effect, can tired loosening even fracture, when serious even can cause pay off rack to fly out, accidents caused.
[utility model content]
The technical problems to be solved in the utility model, be to provide a kind of cage stranding machine pay off rack supporting construction, the centrifugal intertia force that it produces in the time of can be with the rotation of drum and pay off rack and the transmission held separate of back twist campaign make and twist the cage more balance that turns round, safety and reliability.
The utility model is achieved in that
A kind of cage stranding machine pay off rack of the utility model supporting construction, it comprises pay off rack, capstan winch, drum, the back twist device, place one or more pay off racks between per two capstan winches, place drum on the described pay off rack, it also comprises first centration axis, second centration axis, semiaxis, the left end of described pay off rack connects semiaxis and connects the first centration axis device by an axle sleeve, described first centration axis is set on the described semiaxis, and it is affixed with first capstan winch, described semiaxis connects described back twist device, the right-hand member of described pay off rack connects second centration axis, and described second centration axis and second capstan winch are affixed;
Further, described back twist device comprises back twist crank and back twist ring, and described semiaxis connects described back twist ring by described back twist crank;
Further, described back twist device is the back twist of full-depth tooth wheel;
Further, described semiaxis is a forging.
Advantage of the present utility model is:
Pay off rack of the present utility model two ends all adopt first centration axis and second centration axis that connect firmly with the capstan winch hole to support, be pay off rack by bearings on first centration axis and second centration axis, and the back twist campaign of pay off rack is transmitted by semiaxis, the huge centrifugal intertia force that is produced when being the rotation of drum and pay off rack is born by good first centration axis of rigidity and second centration axis, and semiaxis only bears the power of back twist campaign, thereby solved the problem of old-fashioned structure, the running of feasible strand cage is balance more, safety and reliability.
[description of drawings]
In conjunction with the embodiments the utility model is further described with reference to the accompanying drawings.
Fig. 1 is the structural representation of existing cage winch.
Fig. 2 is the structural representation of the utility model embodiment.
[embodiment]
Consult Fig. 2, embodiment is described in detail to the utility model.
As shown in Figure 2, the utility model one embodiment comprises placement pay off rack 2 between first capstan winch 1, pay off rack 2, second capstan winch 4, drum 3, back twist ring 5, back twist crank 6, the first capstan winches 1, the second capstan winch 4, places drum 3 on the described pay off rack 2.The left end of pay off rack 2 and semiaxis 10 are affixed, and affixed by an axle sleeve 91 and first centration axis 9, and in the halving hole of described first capstan winch 1, described semiaxis 10 is connected with back twist ring 5 by back twist crank 6 described first centration axis 9 by bearings.The right-hand member of described pay off rack 2 is connected with second centration axis 11, and described second centration axis 11 leans on bearings in the halving hole of described second capstan winch 4.Pay off rack 2 be by bearings on first centration axis 9 and second centration axis 11, the huge centrifugal intertia force that is produced in the time of described drum 3 and pay off rack 2 rotations, bear by good first centration axis 9 of rigidity and second centration axis 11, and the back twist campaign is transmitted by semiaxis 10, only bears moment of torsion so transmit the semiaxis 10 of back twist campaign.The running of this feasible strand cage is balance, safety and reliability more.This supporting construction, we are referred to as " unloading mechanism ", when using " unloading mechanism " transformation cage winch, note the balance of pay off rack 2, and this point is even more important to adjusting cage winch; In addition, the processing technology of semiaxis 10 is also very important, if possible, takes forging as far as possible, to improve semiaxis 10 reliability during operation; Pay off rack back twist mode is definite in the strand cage, concerning general low speed cage winch, still can adopt 5 back twists of back twist ring, and concerning the high speed cage winch, then should adopt full-depth tooth wheel back twist device, to be suitable for the needs of high-speed motion.
The above, it only is the utility model preferred embodiment, so can not limit the scope that the utility model is implemented according to this, i.e. the equivalence of doing according to the utility model claim and description changes and modifies, and all should still belong in the scope that the utility model contains.
