Abstract
The invention relates to a cross shaft structure. The cross shaft structure comprises a longitudinal shaft and a transverse shaft which are mutually perpendicular, wherein oil holes penetrating through each other are formed in the longitudinal shaft and the transverse shaft and comprise end part holes provided with spiral slots as well as backflow part holes; axes of the end part holes and the backflow part holes are not located on the same plane; and magnets are mounted in the spiral slots. According to the scheme, the structure is simple, by means of an eccentric oil hole structure, rigidity of a shaft diameter stress surface of a cross shaft is reduced, a bearing area is increased by the aid of elastic deformation during operation, so that the contact stress is reduced and tends to be uniformly distributed, a lubricating agent is injected through the oil holes, the lubricating condition is improved, and the service life is prolonged; and besides, during connecting, operation is performed stably and torque is transmitted through tight absorption of the magnets and connecting parts.
Description
Technical field
The present invention relates to a kind of cross axle, be specifically related to for the cross axle structure in engineering machinery and vehicle drive unit.
Background technique
At present, be widely used in the articulated cross shaft very easily corrupted of heavy duty on the main transmission of the heavy machineries such as rougher of hot strip mill machine, heavy merchant mill, punch, middle Wide and Thick Slab and steckel mill and super-heavy load universal coupling with spider: be owing to being used in the bulky of heavy duty in above-mentioned main equipment and super-heavy load coupling on the one hand, swing diameter H0 is between φ 650mm to 1300mm, moment of torsion is at 2300KNm to 19405KNm, and the impulsive load causing it to be operationally subject to and moment of torsion are very large; On the other hand, it also will be subject to the very high alternating shock load of frequency in operation process, can produce larger friction, cause wearing and tearing; Simultaneously because coupling is Structural Hardware, usually also can produce larger noise when rubbing, therefore, very easily there is fracture and cause scrapping in the critical component cross axle of heavy duty and super-heavy load cross axle type coupling.
Summary of the invention
The present invention seeks to provide a kind of to overcome the deficiencies in the prior art, in the process of transmitting torque, effectively can avoid friction, the stress reducing the spindle nose root of cross axle is concentrated, and improves design of part intensity and technological universal-joint cross trunnion.
For achieving the above object, the technical solution used in the present invention is: a kind of cross axle structure, comprises the orthogonal longitudinal axis and transverse axis, and the described longitudinal axis and transverse axis have mutually through oilhole, and described oilhole comprises with spiral fluted end hole and hole, backflow portion; Described end hole and backflow portion axially bored line be not at same plane; Described spiral chute is built with magnet.
Improve further as the present invention, described magnet is rare earth permanent magnet.
Improve further as the present invention, between the described longitudinal axis and transverse axis, joint is with oval arc transition.
Due to the utilization of technique scheme, the present invention compared with prior art has following advantages:
The cross axle structure of the present invention program, structure is simple, the oil hole structure of eccentric, reduce the rigidity of cross axle diameter of axle stress surface, by means of resiliently deformable, loaded area is increased during running, thus reduce contact stress and be tending towards being uniformly distributed, inject oiling agent by oilhole, be conducive to improving lubricating condition and increasing the service life; In addition, the tight adhesive again by magnet and link during connection, and make its smooth running, transmitting torque.
Accompanying drawing explanation
Below in conjunction with accompanying drawing, technical solution of the present invention is described further:
Accompanying drawing 1 is the structural representation of a kind of cross axle structure of the present invention;
Wherein: 1, the longitudinal axis; 2, transverse axis; 3, spiral chute; 4, end hole; 5, hole, backflow portion; 6, magnet; 7, oval camber line.
embodiment
Below in conjunction with drawings and the specific embodiments, the present invention is described in further detail.
Accompanying drawing 1 is a kind of cross axle structure of the present invention, comprises the orthogonal longitudinal axis 1 and transverse axis 2, and the described longitudinal axis 1 and transverse axis 2 have mutually through oilhole, and described oilhole comprises end hole 4 with spiral chute 3 and hole, backflow portion 5; Described end hole 4 and hole 5, backflow portion axis be not at same plane; Described spiral chute 3 is built with magnet 6; Described magnet 6 is rare earth permanent magnet; Structure is simple, and the oil hole structure of eccentric, reduces the rigidity of cross axle diameter of axle stress surface, by means of resiliently deformable, loaded area is increased during running, thus reduce contact stress and be tending towards being uniformly distributed, inject oiling agent by oilhole, be conducive to improving lubricating condition and increasing the service life; In addition, the tight adhesive again by magnet and link during connection, completes moment of torsion transmittance process by magnetic force, effectively prevent the larger friction and noise that produce in transmitting torque process in prior art, and makes its smooth running, transmitting torque.
Between the longitudinal axis 1 and transverse axis 2, joint is with the transition of oval camber line 7, and without the sudden change of sectional shape, the stress thus alleviating cross axle spindle nose root is concentrated, and improves the intensity of cross axle, decreases the possibility of fatigue fracture.
Below be only embody rule example of the present invention, protection scope of the present invention is not constituted any limitation.The technological scheme that all employing equivalents or equivalence are replaced and formed, all drops within rights protection scope of the present invention.
