Working principle of the present utility model is such: with common universal coupling with spider, compare; universal coupling with spider with overload protection function has increased the overload protection arrangement be comprised of mandrel, hollow shaft and overload protection bolt between universal-joint fork and splined shaft, to realize the overload protection of universal coupling with spider.Wherein the limit load value of overload protection is determined by specification and the quantity of overload protection bolt, and can be from main regulation.But the limit load value of noting overload protection need be less than the limit load of universal coupling with spider bulk material, in actual use, the failure torque with universal coupling with spider of overload protection function is 95% of its rated torque.
Universal coupling with spider with overload protection function connects respectively power intake and clutch end by pawl dish flange yoke.During normal operation, the same with common universal coupling with spider, can realize the power transmission of diaxon on different axis.When transmitting torque transships; at first the overload protection bolt cuts off; now mandrel and hollow shaft relatively rotate, and the universal coupling with spider with overload protection function is transmitting torque not, play the effect that protection has the universal coupling with spider miscellaneous part of overload protection function.
Obvious relative position mark is arranged as be carved with groove or be provided with flange at adpting flange and end face flange, when relatively rotating appears in mandrel and hollow shaft, can judge the overload protection bolt and cut off, can normally use after changing the overload protection bolt.
The utility model has the advantage of: the universal coupling with spider maintenance expenses, by 0.1 ten thousand/(the root * month) after use of reducing to 1.8 ten thousand/(the root * month) before using, has reduced 94.5%; The power distribution gearbox maintenance expenses, by 0.5 ten thousand/(the platform * month) after use of reducing to 1.5 ten thousand/(the platform * month) before using, has reduced 66.7%; The universal coupling with spider rate of fault is reduced to 0.13% after use by 0.75% before using, and has reduced by 82.7%; Produce productivity and rise to 96.85% after use by 96.8% before using, improved 0.05%.
Universal coupling with spider with overload protection function is simple in structure, easy to operate, it is convenient to change; after using, manufacturing efficiency improves greatly; the maintenance expenses of mechanical spare part reduces greatly; both solved the high difficult problem of maintenance expenses; reduced again the equipment obstacle management time; improved the equipment productivity, and making is simple, fabricating cost is low, be easy to popularization, market prospects are very wide.
