Abstract
The invention discloses a wear-resistant cross axle universal joint, which comprises a cross axle, an oil seal, bearing needles and an axle sleeve, wherein the bearing needles and the axle sleeve are arranged on a cross axle head; the outer end part of the axle sleeve upwards bulges to form a spherical surface; a gasket is arranged between the axle sleeve and the cross axle; the inner end face of the axle sleeve is provided with a circular groove; needle locating rings are arranged in the circular groove; the outer surface of the axle sleeve is provided with a wear-resistant layer. The wear-resistant cross axle universal joint disclosed by the invention has the advantages that the structural design is reasonable, the rotation is flexible, the stress distribution is even after a force is applied to the cross axle universal joint, the integral structure is high in strength, the wear resistance is improved, the repair rate is reduced, manufacturing is convenient, and the like, so that the wear-resistant cross axle universal joint is suitable for being popularized and used.
Description
Technical field
The present invention relates to a kind of Hooke's joint, particularly a kind of anti abrasive Hooke's joint.
Background technique
Conventional universal joint is generally comprised of cross axle, oil sealing, bearing needle and axle sleeve, the end of the axle sleeve of existing Hooke's joint is directly and contacts with the end of cross axle, owing to there being machining error, between cross axle and axle sleeve, there is gap, contact inhomogeneous, can cause between cross axle and axle sleeve and rub, resistance to motion increases.And the differential spider gimbal design size that is two stage reduction gear due to automobile is less, during work, bear larger impulsive load and alternating bending load, working surface bears larger pressure stress and frictional force, therefore, Hooke's joint should possess higher resistance to flexure and contact fatigue strength, and surface should have higher hardness, wear resistance and seizure resistance, and there are enough intensity and toughness in heart portion.The axle sleeve of the Hooke's joint using at present adopts carburizing, quenching technical, and surface is coating not, easily causes differential spider universal joint by wearing and tearing in advance, the stuck problem such as even twist off, and rate of fault is higher, reduces its working life.
Summary of the invention
Object of the present invention is just to provide a kind of reasonable in design, rotates flexibly the anti abrasive Hooke's joint of long service life.
To achieve these goals, the technical solution used in the present invention is such: anti abrasive Hooke's joint of the present invention, comprise cross axle, oil sealing and be arranged on bearing needle and the axle sleeve on cross axle spindle nose, described axle sleeve outer end outwardly convex is sphere, between axle sleeve and cross axle, be provided with pad, axle sleeve interior edge face is provided with circular groove, is provided with needle roller positioning ring in circular groove, and sleeve outer surface is provided with wearing layer.
As preferably, the section of described needle roller positioning ring is arc, and the end face that oil sealing contacts with bearing needle is provided with arc-shaped recess, and arc-shaped recess and needle roller positioning ring match.
As preferably, described wearing layer is made by organic resin and molybdenum disulfide high-abrasive material.
As preferably, the thickness of described wearing layer is 0.010-0.015mm.
Compared with prior art, the invention has the advantages that: reasonable in design of the present invention, rotate flexibly, stressed rear stress distribution is even, and overall construction intensity is high, and axle sleeve surface is provided with wearing layer, can solve the problem of earlier period damage, and improved wear-resisting property, reduced repair rate, and there is the advantages such as convenient manufacture; Between axle sleeve and cross axle, be provided with pad, reduce friction, it is rotated flexibly; Axle sleeve is provided with needle roller positioning ring, has strengthened the sealability of oil sealing, is applicable to promoting the use of.
Accompanying drawing explanation
Fig. 1 is structural representation of the present invention.
In figure: 1, cross axle; 2, oil sealing; 3, bearing needle; 4, axle sleeve; 5, pad; 6, needle roller positioning ring; 7, wearing layer.
Embodiment
Below in conjunction with accompanying drawing, the invention will be further described.
Referring to Fig. 1, anti abrasive Hooke's joint of the present invention, comprise cross axle 1, oil sealing 2 and be arranged on bearing needle 3 and the axle sleeve 4 on cross axle 1 spindle nose, described axle sleeve 4 outer end outwardly convexs are sphere, between axle sleeve 4 and cross axle 1, be provided with pad 5, axle sleeve 4 interior edge faces are provided with circular groove, in circular groove, be provided with needle roller positioning ring 6, axle sleeve 4 outer surfaces are provided with wearing layer 7, the section of described needle roller positioning ring 6 is arc, oil sealing 2 is provided with arc-shaped recess with the end face that bearing needle 3 contacts, arc-shaped recess and needle roller positioning ring 6 match, both increased the area of contact of oil sealing 2 with needle roller positioning ring 6, strengthened again the sealability of oil sealing 2, described wearing layer 7 is made by organic resin and molybdenum disulfide high-abrasive material, the thickness of described wearing layer 7 is 0.010-0.015mm.
During assembling, in the gap between cross axle 1, bearing needle 3 and axle sleeve 4, be filled with lubricant oil, and sealed by seal ring, like this, after having assembled, 100,000 li of continuously-runnings are above and exempt to refuel, saved the trouble of periodical repair, thereby used easily.Axle sleeve 4 surfaces are provided with wearing layer 7, can solve the problem of earlier period damage, and have improved wear-resisting property, have reduced repair rate, and have the advantages such as convenient manufacture; Between axle sleeve 4 and cross axle 1, be provided with pad 5, reduce friction, it is rotated flexibly; Axle sleeve 4 is provided with needle roller positioning ring 6, has strengthened the sealability of oil sealing 2, is applicable to promoting the use of.
Claims (4)
