More than be the basic structure of the utility model, because of power take-off lubricant oil and the transmission oil trade mark different, in the existing technology with back-to-back oil sealing separately with two kinds of fluid; Cause oil sealing B insufficient lubrication; Unlubricated oil circuit flows through, and causes oil sealing early failue, in addition tank filler sleeve again on this structure; First circulating oil path that spline through the utility model goes tooth to become can be realized the purpose of oil leab.Because of transmission shaft and power take-off input shaft are little Spielpassung; Lubricant oil can arrive oil sealing B place through this gap; (lubricant oil circulates through this space but can't reflux; Give oil sealing B lubricated fully, and can take away oil seal lip in time, guarantee the lubricated and radiating effect that oil sealing B is good because of fricative heat.
Improve as the utility model, double-row angular contact bal bearing is press fit on the gear, and they are connected with the power take-off output shaft through spline, and through the total member of the locked formation of the locking nut of upper end, total member is assembled on the power take-off housing; Said power take-off housing is provided with arc groove A; Double-row angular contact bal bearing is nonstandard bearing, its outer ring be provided with radial direction oil hole and along the hole annular groove B of inwall circumference, oilhole aligns with annular groove B; It is the second circulating lubrication oil duct that arc groove A, annular groove B, oilhole, bearing race, oil sealing D join successively.
Oilhole quantity on the double-row angular bearing outer ring can be 1 or 2 (concrete relevant with the oilhole size, the aperture greatly then one it is enough, the aperture I is designed to symmetrically arranged 2.Lubricating oil is through arc groove A and annular groove B, and the bearing radial direction oil hole gets into bearing race then; Arrive oil sealing D place at last, when running up, lubricant oil is formed " pump suction " and " extruding " effect because of bearing roller; Lubrication oil circulation is flowed, give entire mechanism good lubricating.
Owing to adopted above-mentioned technological scheme, the acquisition of technology progress of the utility model institute is:
(1) remove the spline tooth structure in the utilization of spline connection part and form the axial lubrication road, simple in structure, be easy to realize, avoided the design of special oilhole, reduced cost;
(2) in the gear-box of splash lubrication; The zone design lubrication oil circulation flow circuits that need lubricate in the part; Lubricant oil can be flowed in oil duct, can not only make lubricant oil arrival need lubricated zone like this, can also the heat that should the zone produces be taken away;
(3) through on bearing outer ring, increasing radial direction oil, and cooperate, make the local circulating lubrication oil duct that forms, reach the purpose of lubricated bottom oil sealing with the housing annular groove.
The utility model is applicable in the car transmissions, as the circulating lubrication oil circuit.
The utility model below will combine Figure of description and specific embodiment to do further explain.
