Abstract
The utility model discloses a kind of oblique slot type heavy type universal-joint cross trunnions, it mainly include cross axle, outer ring, needle roller, sealing ring, u font groove, design has biserial u font groove on four axle journals of cross axle, needle roller is installed in u font groove, sealing ring is installed to seal needle roller in needle roller outer side contacts outer ring between outer ring and the axle journal of cross axle.The utility model adds taper design by trunnion journal surface u font groove, increase effectively needle roller and trunnion journal contact area, heavily loaded load is reduced to the percussion of needle roller and axle journal, so that needle roller and trunnion journal contact stress is reduced by 20% or more, greatly improves the bearing wear service life.
Description
Technical field
The utility model relates to the fields of universal joint, and in particular to a kind of oblique slot type heavy type universal-joint cross trunnion.
Background technique
Universal joint is typically mounted on section fork, does small size reciprocating motion with output shaft by the input shaft with angle.Ten
The design of word shaft neck is usually expressed as the concordant cylindrical surface of rule.
In low-speed heave-load operating condition, maximum weighted needle roller connects universal-joint cross trunnion with the extruding in journal contact nearby periphery
It is larger to touch stress, needle roller does sinusoidal or cosine between cross axle cylindrical journal surface and outer ring and moves back and forth.Since load is big
Frequency is high, will cause trunnion journal and wear-out failure namely early fatigue peeling occurs.Excessive contact stress and high frequency rushes
Hitting load is the root that heavy universal-joint cross trunnion journal surface early fatigue peels off.
Utility model content
The purpose of the utility model is to overcome the shortcomings of the prior art, and provide a kind of oblique slot type heavy type universal joint
Cross axle.
The purpose of this utility model is completed by following technical solution: this oblique slot type heavy type universal joint cross
Axis mainly includes cross axle, outer ring, needle roller, sealing ring, u font groove, and design has biserial u word on four axle journals of cross axle
Connected in star, u font groove is interior to install needle roller, and sealing ring is installed between outer ring and the axle journal of cross axle in needle roller outer side contacts outer ring
To seal needle roller.The groove diameter of the u font groove is slightly larger than needle roller diameter and u font groove quantity is equal with needle roller.Institute
It states u font groove and is designed as tapered structure.
The amount of taper δ of the u font groove tapered configuration is generally 0.005-0.020mm.
The utility model has the following beneficial effects:
1, the utility model is in the case where certain gives universal-joint cross trunnion outer dimension inconvenience, and does not influence cardan axis
On the basis of holding original kinetic characteristic, by increasing the taper between needle roller and axle journal between contact area and needle roller and axle journal
Gap has the function that reduce contact stress and slows down shock loading, to improve the wear resistance of universal-joint cross trunnion.
2, the utility model adds taper design by trunnion journal surface u font groove, increases effectively needle roller and ten
Word shaft neck contact area reduces heavily loaded load to the percussion of needle roller and axle journal, contacts needle roller with trunnion journal and answer
Power reduces by 20% or more, greatly improves the bearing wear service life.

Specific embodiment
Detailed introduction is done to the utility model below in conjunction with attached drawing:
Embodiment: as shown in the picture, this oblique slot type heavy type universal-joint cross trunnion mainly includes cross axle 1, outer ring 2, rolling
Needle 3, sealing ring 4, u font groove 5, design has biserial u font groove 5, peace in u font groove 5 on four axle journals of cross axle 1
Needle roller 3 is filled, the outer side contacts outer ring 2 of needle roller 3 installs sealing ring 4 and seals needle roller 3 between outer ring 2 and the axle journal of cross axle 1.U font
The groove diameter of groove 5 is slightly larger than 3 diameter of needle roller and 5 quantity of u font groove is equal with needle roller 3, increases needle roller 3 and cross axle
The contact area of 1 axle journal weakens the percussion between needle roller 3 and 1 axle journal of cross axle, to reach to reduce contact stress
To the purpose for improving universal-joint cross trunnion wear-out life.U font groove 5 is designed as tapered structure, and its amount of taper δ is general
For 0.005-0.020mm.5 depth of u font groove and diameter are determined according to specific operating condition, specific structure.Due to u font groove 5
Presence, 3 diameter of needle roller can be with respect to overstriking, to improve the bearing capacity of needle roller 3.The utility model does not change bearing movable
Can, do not change bearing size.
It is understood that it will be understood by those skilled in the art that the technical solution of the utility model and utility model structure
Think of is subject to equivalent substitution or change all and should belong to the protection scope of the utility model the attached claims.
