Couplings belong to the category of general mechanical parts. Common couplings include diaphragm couplings, drum gear couplings, universal couplings, safety couplings, elastic couplings and serpentine spring couplings.

Advantages

The (I) is simple to manufacture and install.

The (II) expansion sleeve has a long service life.

(III) expansion sleeve in the overload, will lose the coupling function, can protect the equipment from damage.

(IV) expansion sleeve coupling can withstand multiple loads, and its structure can be made into a variety of styles. According to the size of the installation load, it can also be used in series with multiple expansion sleeves.
