Cardan shaft's correct installment, the reasonable use and the regular maintenance regarding guaranteed that its work quality and the working life are very important, proposed specially the following several matters needing attention, ask respectfully the user to cooperate: ■regarding the expandable belt spline vice-cardan shaft, installs when must inspect the splined tube and the spline shaft should according to symbolize that the position coordinates, guaranteed that the both sides jaw bearing hole spool thread's phase difference does not surpass 1°, otherwise is impossible to cause the driveshaft with to be equal from moving axis's angular speed, when revolves has the improper impact. The rotational speed is higher, then the consequence is more serious. ■cardan shaft's both sides may make initiative or the driven end in principle, installs when should conform to transmission system's design drawing to stipulate, but the following two spots still need to remind the user attention: （1）the spline fit place should be far away from the vibration source and the impact source as far as possible. �。�2）avoids the contamination or the water as far as possible enters the spline fitting surface. ■before the installment, is clean the flange adjoining plane's rust prevention fat clean, and eliminates possibly reduces the contact face friction force or the reduced joint surface contact area disadvantage factor. ■should avoid the long-term overload use and operation accident's occurrence. ■after the belt load works a class, should inspect the flange stop bolt whether to become less crowded, and stipulated screws tight the moment of force to screw tight once more, is so redundant several classes, until screws tight the strength to be at the steady state. ■cardan shaft's knuckle bearing and the spline vice-place, under the elevated temperature service condition should every other 1-2 week stuffing one time, in the general working condition on the continuous working 500 hour Canada fat one time, under the interrupted working condition, every three month stuffing one time, the fat trademark use 2 industry lithium base lubricant. ■in the work revolution, should the continuous observation cardan shaft whether to have the unusual radial wobble and the bearing gives off heat and so on phenomena, discovered that these phenomena must service promptly. ■normal work's cardan shaft, the maintenance time carries on the service from a half year to one year or along with the equipment, the maintenance check project is generally: �。�1）the bearing race, the cross axle axis axis must or presses the table with roller's wearing capacity > 0.25mm to need to replace. （2）the bearing end surface and the files chart contact face and the wearing capacity > 0.35mm needs to replace. �。�3）the spline vice-mating surface wearing capacity > 0.35mm needs to replace. ■ in possible, because revolves the cardan shaft causes the person and equipment accident's each place must take the suitable safety protection measure.
