Abstract
The utility model discloses a kind of sprayed molybdenum synchronous ring, comprise synchronous ring body, the conical surface of synchronous ring body is provided with thread compound line, and thread compound line is fine thread oil line, the crest width of fine thread oil line is 0.3 ~ 0.7mm, and the pitch of fine thread oil line is 1.3 ~ 1.7mm; The conical surface of synchronous ring body is along the circumferential direction also at least provided with an axial oil groove, and axial oil groove and synchronous ring body are the overall structure of a forging molding.By thread compound line being improved to fine thread oil line, like this, because the crest of fine thread oil line compared with normal thread compound line is thinner, so in identical pitch situation, the helical cross section oil extraction area of fine thread oil line is larger, and oil extraction better effects if, can take away fricative heat faster, be conducive to the stability improving friction process, thus improve the service life of synchronous ring.Be applicable to synchronized.
Description
Technical field
The utility model relates to synchronized field, particularly relates to a kind of sprayed molybdenum synchronous ring.
Background technology
Synchronous ring in synchronized and synchronous cone are automotive transmissions is make the light noiseless synchronized friction element cooperatively interacted arranged in conjunction with the tooth life-span with prolongation of gear shift.During work, synchronous ring and synchronous cone coordinate generation moment of friction to make active and passive element synchronous in moment, thus realize active and passive element without impacting and light noiseless gear shift.
At present, usually adopt the mode of precision forging to produce sprayed molybdenum synchronous ring, adopt mach mode to produce synchronous cone.Particularly, when producing sprayed molybdenum synchronous ring, first precision forging goes out synchronous ring body, then on the conical surface of synchronous ring body, processing thread compound line, (purposes of thread compound line is in synchronizing process, cut off gear oil oil film, realize synchronous effect), finally sprayed coating molybdenum frictional layer on the synchronous ring body processed again; When producing synchronous cone, first process synchronous cone body, then machining axial oil groove (purposes of axial oil groove is discharged from the conical surface by gear oil) on the antithesis conical surface of synchronous cone body.Following problem is there is in the sprayed molybdenum synchronous ring of this structure and synchronous cone in actual production with when using:
1, because the thread compound line in existing sprayed molybdenum synchronous ring is coarse-pitch thread oil line, its crest is thicker, so in identical pitch situation, its helical cross section oil extraction area is less, oil extraction effect is poor, and like this, it is less that it takes away fricative heat, be unfavorable for the stability improving friction process, thus greatly reduce the service life of synchronous ring;
2, because the axial oil groove on synchronous cone is machined, so mach amount is comparatively large and working (machining) efficiency is lower, cost is higher.
Summary of the invention
The purpose of this utility model is the deficiency in order to overcome above-mentioned background technology, provides a kind of long service life and the low sprayed molybdenum synchronous ring of cost.
In order to realize above object, a kind of sprayed molybdenum synchronous ring that the utility model provides, comprise synchronous ring body, the conical surface of described synchronous ring body is provided with thread compound line, described thread compound line is fine thread oil line, the crest width of described fine thread oil line is 0.3 ~ 0.7mm, and the pitch of described fine thread oil line is 1.3 ~ 1.7mm; The conical surface of described synchronous ring body is along the circumferential direction also at least provided with an axial oil groove, and described axial oil groove and described synchronous ring body are the overall structure of a forging molding.By thread compound line being improved to fine thread oil line, like this, because the crest of fine thread oil line compared with normal thread compound line is thinner, so in identical pitch situation, the helical cross section oil extraction area of fine thread oil line is larger, and oil extraction better effects if, can take away fricative heat faster, be conducive to the stability improving friction process, thus improve the service life of synchronous ring; Meanwhile, by crest width and the pitch of optimal design fine thread oil line, further increasing the service life of synchronous ring; And, by axial oil groove is arranged in synchronous ring, like this, axial oil groove can together with synchronous ring forging molding, and without the need to machining axial oil groove on synchronous cone, thus decrease operation, improve production efficiency, reduce cost.
In such scheme, on the conical surface of described synchronous ring body, sprayed coating has molybdenum frictional layer.
In such scheme, the quantity of the described axial oil groove on the single conical surface of described synchronous ring body is 6 ~ 18.
The utility model is by being improved to fine thread oil line by thread compound line, like this, because the crest of fine thread oil line compared with normal thread compound line is thinner, so in identical pitch situation, the helical cross section oil extraction area of fine thread oil line is larger, and oil extraction better effects if, can take away fricative heat faster, be conducive to the stability improving friction process, thus improve the service life of synchronous ring; Meanwhile, by crest width and the pitch of optimal design fine thread oil line, further increasing the service life of synchronous ring; And, by axial oil groove is arranged in synchronous ring, like this, axial oil groove can together with synchronous ring forging molding, and without the need to machining axial oil groove on synchronous cone, thus decrease operation, improve production efficiency, reduce cost.
The utility model is compared with the prior art, and fully its superiority of display is: long service life, production efficiency are high and cost is low.
