Plum coupling, parts localization
Plum coupling, parts localization:
Plum coupling is due to the elastomeric plum blossom shape and this, according to the elastic body material can be divided into: Rubber shaped plum coupling, polyurethane plum coupling; usually used for polyurethane elastomer. This coupling has been standardized, GB/T5272-2002 developed the five structural forms: LM ( basic), type LMD ( single flange type), LMS ( double flange type ), LMZ-I ( split brake wheel type) and LNZ-II ( whole brake wheel type). Each form has 14 specifications, they apply the shaft hole diameter of d=12-160mm, length L=35-135mm nominal torque shaft hole, T=25-25000N.m, [n]=1500-15300r.min allowable speed.
Plum coupling parts localization. Plum coupling is a whole quincunx elastic ring is arranged in two identical half coupling between the convex claws, in order to achieve the two half couplings connection. Through the convex claw and the elastic ring squeeze between the transmission power, through the elastic ring elastic deformation compensation diaxon relativity shift, realize the damping buffer.
On the plum coupling industry, high-end market is still import coupling occupy most of the market share, the reason is our country precision couplings starts late, the market products quality management is also uneven, and advanced foreign enterprises have a certain gap, cause and country outreach axis products competitive disadvantage. In recent years, more and more enterprises begin to pay attention to the quality of the coupling manufacture management, more emphasis on R & D investment, talents, so that the coupling quality continuously improve, basically can replace import couplings, but with foreign advanced enterprises, have a long way to go, believe that after a few years efforts, including coupling, basic components will be the full realization of domestic, as China's equipment manufacturing industry into the international market to provide a guarantee, but also reflect the level of industrialization of a nation 's flag.
