Electric hoist clutch how to ensure stable performance

   Is a small electric wire rope hoist  lifting equipment, for safety reasons, the equipment is shipped configure many security devices, such as the majority of customers are familiar with the stopper, reducer, electric hoist today to introduce you to the clutch, clutch mainly to protect the hoist lifting institutions, but how to ensure stable performance clutch needs to meet the following conditions:
         1,  Rope hoist  friction plates have good thermal conductivity, copper powder metallurgy materials can be used, the friction plate sintered steel backing on both sides.
         2, spline fit sleeve and  lift hoist  gear should be appropriate, such as tight, it is easy to slip adhesive fever, migraine affects loose gear center distance limit deviations. Spline bushing material generally used in cast iron or aluminum bronze can be.
         3, requiring electric hoist in the disc spring stiffness and stability. When designing the spring, according to the test to take the work load of two times the rated load.
         When the hoist is equipped with clutch after lifting 1.5 times more than the rated load, the clutch will protect the lifting mechanism, to a certain extent can make normal use of electric hoist and working.
