Genuine distinction of coupling and diaphragm coupling knowledge

Now more and more people for the benefit of everything, so in the purchase and selection of diaphragm coupling to find a trusted manufacturer, and carefully check, so as not to buy secondary mouth, fake goods and then affect their own production and life. Our company specializes in the production of universal coupling

1, first of all, carefully check the material of the coupling: the coupling is more commonly used materials are phenolic plastic, nylon, ptfe, etc.. But most of the couplings are made of steel, but because the price of steel has been high, some profiteers in the coupling of raw materials under the full momentum! Reduce the size of the steel for better charging! Ordinary steel, carbon steel, malleable steel and other materials are used, and even iron pipes are used instead of steel products. Therefore, from the appearance of the coupling, we can see that there are a lot of differences in color. Most of the low-priced steel in the appearance of white steel has a more obvious difference with the green bearing steel.

2, measure the fastening Angle of the locking nut, which can be used to determine the correct interference of small and medium-sized bearings on the tapered journal. A guide value for fastening Angle A has been established to assist accurate positioning of bearings on tapered journal. Porous metal is a powder material, it has porous structure, if it is immersed in lubricating oil, so that the pores are filled with lubricating oil, into an oil-bearing, with self-lubricating performance. Porous metal materials have little toughness and are only suitable for smooth non-impact loads and medium and small speeds.

Diaphragm coupling in developed places has been very common, compared with the gear coupling, no relative sliding, no lubrication, sealing, no noise, basic need not maintenance, easy to manufacture, can partly replace the gear coupling. The diaphragm coupling consists of several groups of diaphragms (stainless steel sheet) interlaced with bolts connected to the two halves of the coupling. Each group of diaphragms is composed of several overlapping pieces. The diaphragm is divided into connecting rod type and the whole piece of different shapes. Diaphragm coupling on the elastic deformation of the diaphragm to compensate for the two axes relative displacement, is a kind of high-performance metal flexible coupling components, no lubrication, structure is compact, high intensity, long service life, no rotating clearance, not influenced by temperature and oil pollution, has the characteristics of acid and alkali corrosion resistance, suitable for high temperature, high speed, working condition of a corrosive medium environment of shaft transmission.

A diaphragm coupling consists of at least one diaphragm and two shaft sleeves. The diaphragm is fastened to the bushing with pins without loosening or causing recoil between the diaphragm and the bushing. Some manufacturers offer two diaphragms, while others offer three diaphragms with one or two rigid elements in the middle, connected to the sleeves on both sides. The difference between a single diaphragm coupling and a double diaphragm coupling is the ability to deal with various deviations, which requires complex bending of the diaphragm, so the single diaphragm coupling is not suitable for eccentricity. The double diaphragm coupling can bend in different directions at the same time to compensate for eccentricity.
