Said Hooke's joint comprises cross axle, needle roller and bearing housing; Said needle roller is arranged at the spindle nose periphery of cross axle, and the spindle nose of said cross axle is arranged in the bearing housing through needle roller, is provided with oil sealing between said cross axle and the bearing housing; Said cage openings end is provided with dust-proof cover; Said dust-proof cover is a bowl type, and the dust-proof cover back-off of said bowl type all offers shoe cream room in the opening end of bearing housing on the spindle nose end face of said cross axle.
Said external splines surfaces coated is covered with nylon layer.
Be equipped with skeleton I in the said dust-proof cover.
Said oil sealing periphery is coated with skeleton II.
Said oil sealing and dust-proof cover adopt hydrogenated nitrile-butadiene rubber to process.
Compared with prior art, the beneficial effect of the utility model is:
A kind of non-maintaining cardan universal joint driving-shaft assembly of the utility model, the external splines surfaces coated of its splined shaft outer rim is covered with nylon layer, and itself has self-lubricating function nylon; When assembling, only need add minor amounts of lubricants; Need not during use to be lubricated maintenance again, and spline housing is set with the dust-proof cover pipe outward, between dustproof vestlet and the spline housing through the seal ring sealing; Can prevent that foreign material from getting into spline pair, make spline pair avoid safeguarding;
And the dust-proof cover of Hooke's joint is bowl type back-off in the cage openings end, and dust-proof cover adopts the hydrogenation nitrile rubber to process, and four spindle noses of cross axle are separate; All offer shoe cream room on the spindle nose end face, after cross axle and the needle bearing assembling, the gap in shoe cream room and the needle bearing is filled up by grease; Air is discharged, and forms a negative cavity, and dust-proof cover wraps tightly under action of air pressure on the bearing housing end face; And can closely cooperate with the cylindrical and the end face of cross axle, can guarantee that grease do not reveal, it is inner to prevent that dirt such as outside silt from getting into bearing; Its sealability is better, makes Hooke's joint avoid safeguarding, has improved its working life.
