The invention discloses a high-sealing oil-lubricated universal joint assembly. The high-sealing oil-lubricated universal joint assembly comprises a cross shaft, wherein shaft heads are arranged on four ends of the cross shaft, shaft sleeves sleeve the shaft heads, and sealing rings are arranged between the shaft sleeves and the cross shaft. The high-sealing oil-lubricated universal joint assembly is characterized in that a plurality of oil dividing grooves are formed in the inner walls of the shaft sleeves, sealing covers are connected to the outer end surfaces of the shaft sleeves, the sealing rings are pressed between the shaft sleeves and the sealing covers, annular cavities of which the cross sections are elliptic are formed in the sealing rings, oil storage holes are formed in the outer ends of the shaft heads, and a plurality of oil guide grooves are formed in the end surfaces of the shaft heads and around the oil storage holes. According to the high-sealing oil-lubricated universal joint assembly, the sealing rings in which the elliptic cavities are formed are arranged, and the sealing pressing covers are matched, so that the sealing rings are close to the sealing surfaces under the action of the sealing pressing covers, so as to achieve a reliable sealing effect; the oil dividing grooves are formed in the inner walls of the shaft sleeves, and the oil guide grooves are formed in the end surfaces of the shaft heads, so that lubricating oil can quickly, uniformly and fully act between the shaft sleeves and a cross universal joint, and the service life of the shaft sleeves is prolonged.
Description
[technical field]
The present invention relates to the technical field of auto parts machinery, particularly the technical field of the oil lubrication universal joint assembly of a kind of high sealing.
[background technology]
Universal joint is the parts realizing varied angle transmission of power, and for needing the position changing transmission axis direction, it is " joint " parts of the universal transmission mechanism of automobile driving system. Universal joint and transmission shaft combination, be called universal transmission mechanism.
By whether universal joint has obvious elasticity can be divided into rigidity universal joint and flexible universal joint on torsional direction. Rigidity universal joint is divided into not constant velocity cardan joint (conventional is joint spider formula), accurate constant velocity cardan joint (such as duplex formula universal joint) and constant velocity cardan joint (such as rzeppa joint) three kinds.
Universal-joint-pin type universal joint is the not constant velocity cardan joint widely used on automobile. Universal-joint-pin type universal saves another joint spider, the compositions such as two universal joint forks and four needle bearings. Hole on two universal joints fork be enclosed within respectively joint spider two on axle journal. Like this when main drive shaft rotates, driven shaft gets final product concomitant rotation, can swing in any direction around joint spider center again, has so just adapted to angle and the needs of the same change of distance.
It is simple that joint spider formula rigidity universal joint has structure, the advantage that transmission efficiency is high, but, the oil sealing of current universal-joint-pin type universal joint is all adopt the common circular or circular sealing-ring of V shape, this kind of oil sealing sealing weak effect on Hooke's joint, inner lubricating oil, easily to external leakage, reduces the work-ing life of Hooke's joint and axle sleeve.
[summary of the invention]
