Coupling composition and diaphragm coupling deformation knowledge
Components of coupling:
Coupling components include two-half couplings, coupling accessories (torque transfer bolts, elastic connectors) and baffle bolts, etc., which are designed to optimize. First of all, most couplings have specific structural shape and size of components, such as TMS plum coupling, TMB high efficiency elastic coupling, TMG diaphragm coupling, HL pin coupling, TL coupling and so on. The strength performance of these couplings and the structural shape and size of the coupling components have been standardized. This is the standard basis for coupling manufacturers to manufacture couplings; And there are a lot of coupling is only a coupling shape and structure assembly graphics, which requires coupling manufacturers according to the coupling nominal torque and transmission system users actual use conditions optimization design of the specific structure shape size of each component of the coupling, such as, a variety of drum gear coupling series of coupling, ZL series of coupling and so on. For example, TMZ drum type coupling modulus and the number of teeth to determine, determine the width of the internal and external teeth, determine the two half coupling flange thickness, the two half coupling torque transfer bolt diameter and number and strength grade to determine; ZL coupling coat thickness and ZL coupling accessories nylon pin diameter and number and nylon pin grade, these shape size differences will affect the strength of the coupling performance. Of course, in the design of the coupling structure size at the same time, according to the coupling nominal torque and transmission system user specific strength requirements, optimize the design of two half coupling material and heat treatment form strength, in order to ensure that the strength of the two half coupling and the overall strength of the transmission system match, and push coupling accessories strength performance nearly coupling nominal torque, so, After the coupling components of precision machining manufacturing to get high quality high quality coupling series products ah. Often similar to the coupling product is reflected in a lot of seemingly subtle ah.
Elastic deformation of diaphragm coupling:
TMG diaphragm coupling relies on the elastic deformation of the diaphragm to compensate the relative displacement of the two axles. It is a high performance flexible coupling of metal elastic elements, without lubrication, compact structure, high strength, long service life, no rotation clearance, not affected by temperature and oil pollution, with the characteristics of acid resistance, alkali resistance and corrosion resistance. Suitable for high temperature, high speed, corrosive medium working environment of shafting drive, widely used in various mechanical devices of shafting drive, Such as water pump (especially high-power, chemical pump), extension (high-speed), compressor, hydraulic machinery, petroleum machinery, printing machinery, textile machinery, chemical machinery, mining machinery, metallurgical machinery, aviation (helicopter), ship high-speed power transmission system, steam turbine, piston type power mechanical transmission system, tracked vehicle, As well as the high-speed and high-power mechanical transmission system of the power generation set, it has been widely used in high-speed transmission shafting after the radial dynamic balance.
TMG diaphragm coupling and gear coupling compared, no relative sliding, no need for lubrication, sealing, no noise, basically no maintenance, easy to manufacture, can partially replace gear coupling.
