Abstract
The utility model spline main transmission spindle, comprise spindle body, driving axle housing on described spindle body connects driven shaft by cross axle, has the spline be connected with driving shaft in described driving axle housing, and the inner bottom surface of the root distance driving axle housing of described spline is 350 ~ 450mm.Spline joint is adopted at the driving shaft near motor output end, the effect of this spline is, the follow-up telescoping of axle is ensured in milling train running, a buffering between driving shaft and driving axle housing can be given when there is large impact, avoid the situation occurring directly to clash into rotor, avoid the shock of rotor to damage.
Description
Technical field
The utility model relate to a kind of be suitable for specially or special configuration in the coupling of rolling mill for metal, live axle or spindle, be specifically related to a kind of spline main transmission spindle.
Background technique
Hooks coupling universal coupling utilizes the feature of its mechanism, makes diaxon not at same axis, can realize the diaxon continuous rotary connected when there is axis angle, and reliably transmitting torque and motion.The maximum feature of Hooks coupling universal coupling is that its structure has larger angular compensatory ability, and compact structure, transmission efficiency is high.Hooks coupling universal coupling is used for connecting two axles (driving shaft and driven shaft) in different institutions, makes it common rotation, with the mechanical parts of transmitting torque.Coupling is made up of two halves, connects respectively with driving shaft and driven shaft.General power engine is mostly connected by means of coupling and working machine.Specifically milling train has larger follow-up telescoping amount at running axis, directly can clash into rotor, causing the loss of motor damage when there is large impact.
Model utility content
The purpose of this utility model is to provide a kind of spline main transmission spindle, can provide certain axial follow-up telescoping amount, avoids occurring directly to clash into rotor when impacting, and causes damage.
For achieving the above object, the technical solution of the utility model is: spline main transmission spindle, comprise spindle body, driving axle housing on described spindle body connects driven shaft by cross axle, have the spline be connected with driving shaft in described driving axle housing, the inner bottom surface of the root distance driving axle housing of described spline is 350 ~ 450mm.
When adopting technique scheme, spline joint is adopted at the driving shaft near motor output end, the effect of this spline is, the follow-up telescoping of axle is ensured in milling train running, a buffering between driving shaft and driving axle housing can be given when there is large impact, avoid the situation occurring directly to clash into rotor, avoid the shock of rotor to damage.
Further, the inner bottom surface of the root distance driving shaft of described spline is 400mm.
Further, described driving shaft is provided with guideway by radial screw, and the end of described driving axle housing is provided with the neck coordinated with guideway, and the length of described guideway is greater than the length of the neck of driving axle housing.Above-mentioned setting can carry out guiding and spacing to the follow-up telescoping of axle, avoids driving shaft and driving axle housing directly stressed, on the neck that power can be decomposed driving axle housing and guideway, even if damage, also can be convenient for changing.
Further, the end of described driving shaft is fixed with rubber sheet gasket by screw.Above-mentioned design can play the effect of buffering when there is shock.
Accompanying drawing explanation
Below in conjunction with the drawings and specific embodiments, the utility model is described in further detail:
Fig. 1 is the structural representation of the utility model spline main transmission spindle embodiment.
Embodiment
As shown in Figure 1, the utility model spline main transmission spindle, includes driving axle housing 1, and driving axle housing 1 connects driven shaft by cross axle, have the spline 11 be connected with driving shaft in driving axle housing 1, the inner bottom surface of the root distance driving axle housing 1 of spline 11 is d=400mm.Driving shaft 2 is provided with guideway 3 by radial screw 21, and the end of driving axle housing 1 is provided with the neck 4 coordinated with guideway 3, and the length of guideway 3 is greater than the length of the neck 4 of driving axle housing 1.Above-mentioned setting can carry out guiding and spacing to the follow-up telescoping of axle, avoid driving shaft 2 and driving axle housing 1 directly stressed, on the neck 4 that power can be decomposed driving axle housing 1 and guideway 3, even if damage, also can be convenient for changing.Spline joint is adopted at the driving shaft 2 near motor output end, the effect of this spline is, the follow-up telescoping of axle is ensured in milling train running, a buffering between driving shaft 2 and driving axle housing 1 can be given when there is large impact, avoid the situation occurring directly to clash into rotor, avoid the shock of rotor to damage.Rubber sheet gasket 5 is fixed with by screw in the end of driving shaft 2.Above-mentioned design can play the effect of buffering when there is shock.
Above-described is only preferred implementation of the present utility model; should be understood that; for a person skilled in the art; without departing from the concept of the premise utility; some distortion and improvement can also be made; these also should be considered as protection domain of the present utility model, and these all can not affect effect and the practical applicability of the utility model enforcement.
