The deficiency that this technological scheme also exists is that guard shield adopts its junction of split type to lack sealing mechanism, has the possibility of leaking lubricant oil; Cannot realize forcing thin oil lubricant based on its structure, easily wear and tear in high speed operation, working life has a greatly reduced quality.
Summary of the invention
For the deficiencies in the prior art, the utility model provides a kind of good seal and adopts the drum-shaped tooth type shaft coupling forcing thin oil lubricant.
The technical solution of the utility model is:
A kind of durable drum-shaped tooth type shaft coupling, comprises left lever, left tooth axle sleeve, Steel Cable Baffle Ring, internal tooth casing, left locking nut, guard shield, right locking nut, right pull bar, right tooth axle sleeve and back-up ring, is characterized in that: there is screw thread at the two ends of left lever, left end is for screwing in input shaft, and right-hand member is fastened on left tooth axle sleeve by left locking nut; There is screw thread at the two ends of right pull bar, and right-hand member is for screwing in output shaft, and left end is fastened on right tooth axle sleeve by right locking nut; The right-hand member of left tooth axle sleeve and the left end of right tooth axle sleeve are processed with cydariform external tooth, and the two ends of internal tooth casing are processed with cydariform internal tooth, and left tooth axle sleeve and right tooth axle sleeve engage the two ends being contained in internal tooth casing respectively by crowned teeth, Steel Cable Baffle Ring is equipped with at the two ends of internal tooth casing; Guard shield is split type structure, is bolted as integral sleeve, and back-up ring is arranged on guard shield and between left tooth axle sleeve and right tooth axle sleeve; Described guard shield side is provided with filler opening and opposite side is provided with oil outlet, described filler opening and oil outlet all coordinate left tooth axle sleeve and right tooth axle sleeve to arrange, described filler opening and the external pressure oil lubricating system of oil outlet, adopt after forcing thin oil lubricant, tooth surface abrasion significantly reduces, wear extent is about 10% of grease lubrication, and circulation thin oil can take away rolling heat and the fricative heat of the gear teeth of roll end, effectively prevent gear teeth material surface allowable contact stress and reduces; Described filler opening is also provided with magnetic screen, and its effect prevents the small metal particles of the generation after wearing and tearing from getting back in device along lubrication oil circulation.
Further, the split surface of described guard shield is provided with seal ring, and its effect is the sealing greatly improving device, and its sealing can adopt sealed-for-life after obtaining forcing the cooling support of thin oil lubricant.
Further, described filler opening is also provided with pressure valve, and described pressure valve is provided with pressure regulator, and its effect prevents oil pressure anomalous effects device.
The beneficial effects of the utility model are: the utility model is rational in infrastructure, by forcing thin oil lubricant, tooth surface abrasion significantly reduces, wear extent is about 10% of grease lubrication, circulation thin oil can take away rolling heat and the fricative heat of the gear teeth of roll end, effectively prevent gear teeth material surface allowable contact stress and reduces; Then prevent the small metal particles of the generation after wearing and tearing from getting back in device along lubrication oil circulation by magnetic screen.
