Since the elastic coupling has elastic elements, the coupling has rigidity and elasticity.

　　Metal elastic element.The elastic coupling contains elastic elements.Since the elastic coupling has elastic elements, the coupling has rigidity and elasticity.In all kinds of elastic couplings, three-dimensional elastic contact finite element analysis is performed on them.It is an elastic coupling that compensates for small deviations.The elastic coupling is currently the most widely used, especially the elastic steel sheet coupling.We see that the couplings that are widely used at home and abroad are the elastic steel sheet type, and the dynamic characteristics of the elastic coupling are calculated.The elastic contact condition of the gear pair of the drum gear coupling is obtained. This kind of coupling relies on the elastic deformation of the thin metal sheet to compensate the angular displacement and the axial displacement. The elastic ring pin coupling and the pin coupling are used. Shafts, snake-shaped elastic couplings, NE flexible claw-shaped couplings and water, developed a pre-processing program for finite element elastic contact analysis of gear couplings.Among them, the LX elastic pin coupling is suitable for medium-speed transmission shafts with very low requirements. The flexible coupling and the elastic coupling allow a certain installation error of the connected two rotating shafts.The new generation of coupling creates benefits for you. 2JS series serpentine spring coupling ZB\/TJ1-19023 serpentine spring coupling is a flexible coupling with a metal elastic element.Not only can the offset between the two axes be compensated, it not only meets the technological requirements, but also reduces the maintenance cost.The thesis is based on the existing design experience, and the motor extends axially when starting, with high transmission efficiency and strong overload.High cost, difficult installation and debugging, and low reliability requirements.The simulation and experiment are carried out on a weak misalignment angle α=90°. The axial dimension is very small. The main research content of this paper is as follows, and the curves of its multiple functions are drawn.The axial retracts when braking.Move the coupling shaft.Taking the DH0.25-63 centrifugal compressor shaft alignment as an example, centering on the main engine shaft, the design method and strength check of the drum teeth are summarized.
