Elastic sleeve pin coupling The structure of this type of coupling is similar to that of a flange coupling, except that the coupling bolt is replaced by a pin with an elastic sleeve.Because oil-resistant rubber is commonly used through the pupal shape to improve its elasticity.The matching hole of the half coupling and the shaft can be cylindrical or...
The diaphragm coupling relies on the elastic deformation of the diaphragm to compensate for the relative displacement of the connected two shafts. It is a high-performance flexible coupling with metal elastic elements. It does not require lubrication, has no rotation gap, and is not affected by temperature and oil pollution. The structure is relatively compact, the strength is high, and the service life is long...
The main technical requirement of coupling assembly is to ensure the coaxiality of the two axes. Excessive coaxiality error will cause additional load on the coupling, drive shaft and its bearings, which will cause vibration of the machine and excessive bearing. Early wear, mechanical seal failure, and even...
Diaphragm coupling diaphragms are divided into: continuous polygonal ring, circular ring, separated connecting rod shape, spoke shape, formed diaphragm, and waved diaphragm.The characteristics of continuous polygonal ring and circular ring: each coupling is composed of several diaphragms of equal thickness, and the outer edge of each piece is arc...
The radial movement of the star-shaped elastic coupling due to the centrifugal force during high-speed operation will accelerate its wear, and a shell is added.In addition to preventing dust and oil storage, insufficient thinning may cause interference. Excessive thinning will weaken the strength of the tooth, and the backlash will be very...
Due to the difference in heat inside and outside the metal, the elastic pin coupling will expand unevenly and generate internal stress, which is called thermal stress.If the temperature is too high during annealing to cause graphite cross-section, it will not be easy to cut and cause overheating and deformation during quenching.Decarburization causes soft spots on the surface of the workpiece...
