Description
Technical field
The utility model relates to field of mechanical technique, and more particularly, it relates to a kind of for providing the cross-axle universal shaft coupling of transmission of power effect for machinery industry.
Background technique
Cross-axle universal shaft coupling is also known as universal joint, and being applicable to connect axis has certain deflection and two concurrent aceses that often change of its relative position, to transmit motion and torque.This coupling has the advantages such as transmitted power is large, compact structure, obtains extensive use, belong to machine foundation universal component in the transmission devices such as automobile, tractor and rolling mill.
At present, the cross-axle universal shaft coupling on market in its working procedure, when driving shaft rotate 1 week, driven shaft also corresponding rotation 1 week, but the instantaneous transmission ratio of diaxon is in continuous change, be attended by the additional dynamic loads such as vibration, impact, it is not ideal enough to add lubricating condition.The wearing and tearing aggravation that these all can cause cross-axle universal shaft coupling articulated parts to ask, makes working condition worsen further.Therefore, cross-axle universal shaft coupling is easily worn part, often become the weak link in transmission device, no matter the wearing and tearing of needle roller, trunnion journal and cup internal surface, capital makes bearing play increase and produces pine rolling, to making mutually to clash between rolling element, this not only can unstable wear, and produces larger noise.
In cross-axle universal shaft coupling, needle bearing does limited swing, the trunnion journal of existing structure smooth surface cannot form complete oil film at rolling surface, cause lubricating condition undesirable, when cross-axle universal shaft coupling runs up, due to centrifugal inertia force effect, cause cross axis faces and cup bottom gap to increase, cause cross axle axial motion.
Model utility content
For the deficiency that prior art exists, the purpose of this utility model is to provide a kind of cross-axle universal shaft coupling, and this cross-axle universal shaft coupling can reduce the wearing and tearing of internals, extends its working life.
For achieving the above object, the utility model provides following technological scheme: a kind of cross-axle universal shaft coupling, comprise cross axle, half-coupling and bearing, cross axle comprises some trunnion journals, it is characterized in that, described trunnion journal is provided with some grooves, and described groove is positioned at cross axle diameter of axle side, groove is around cross axle diameter of axle central axis vibrational power flow twist, and described groove is T-slot.
By adopting technique scheme, in order to effectively improve lubricating condition, some spiral grooves are offered in trunnion journal side, oiling agent can be put into inside grooves, improve the lubrication between needle bearing and cross axle, to ensure that cross-axle universal shaft coupling safety uses smoothly, T-shaped groove, structure is simple, is conducive to better depositing oiling agent when using cross-axle universal shaft coupling.
The utility model is set to further: the spacing of described each adjacent grooves is equal, and described slot opening width is less than the distance between two adjacent grooves.
By adopting technique scheme, the spacing of each adjacent grooves is equal, make trunnion journal structural stability, avoid fracture and the breakage of the trunnion journal produced because groove causes being subject to force unbalance, the groove T-shaped opening distance be less than between two adjacent grooves is conducive to trunnion journal side to maximize, increase its area of contact, play better lubrication effect.
The utility model is set to further: described inside grooves surface roughness is 3.2.
By adopting technique scheme, inside grooves smooth surface is conducive to oiling agent and circulates smoothly in inside grooves, avoids Lubricants and blocks the problem brought.
The utility model is set to further: described trunnion journal is provided with elastic cover plate, and described elastic cover plate is connected to trunnion journal end face.
By adopting technique scheme, trunnion journal arranges elastic cover plate, axial pressure can be increased to balance the eccentric inertial force produced by high rotating speed, thus avoid causing cross axis faces and cup bottom gap increase and cause the situation of cross axle axial motion.
The utility model is set to further: described elastic cover plate end face is for circular, and elastic cover plate is connected to trunnion journal end face, and described elastic cover plate area equals trunnion journal face area.
By adopting technique scheme, round and elastic cover plate structure is simple, is convenient to install processing, elastic cover plate is matched with trunnion journal end face, to reach better cross axle axial float.

Embodiment
Referring to figs. 1 through Fig. 3, a kind of cross-axle universal shaft coupling embodiment of the utility model is described further.
As shown in Figure 1 to Figure 3, plant cross-axle universal shaft coupling, comprise cross axle 5, half-coupling 1, bearing, bearing support, knuckle joint 2, knuckle joint 2 two ends connect two cross axles 5 respectively by pin 3, half-coupling 1 is connected on cross axle 5 by straight pin 4, cross axle 5 comprises some trunnion journals 6, described trunnion journal 6 end face has straight-through oilhole, in order to effectively improve lubricating condition, some grooves 7 on described trunnion journal 6, described groove 7 is positioned at the cross axle diameter of axle 6 side, groove 7 center line in the cross axle diameter of axle 6 side twist, described groove 7 cross section is T-slot.The standard that the is shorter in length than T-slot in the T-shaped opening of described T-slot centrally line direction, the spacing of described each adjacent T-shaped groove 7 is equal, and described groove 7T shape opening is less than the distance between two adjacent grooves 7.Some spiral grooves 7 are offered in trunnion journal 6 side, in use, oiling agent can be put into groove 7 inner, improve the lubrication between needle bearing and cross axle 5, to ensure that cross-axle universal shaft coupling safety uses smoothly, T-shaped groove 7 structure is conducive to better depositing oiling agent when using cross-axle universal shaft coupling.The polishing of described groove 7 internal structure, strengthens its smoothness, enables Lubricants free flow.
