Coupling requirements and optimized design structure

Published: 2020-01-11

CouplingThe torque transmission is mainly to set the nominal torque requirement of the transmission system.When the torque transmitting element is overloaded, connect the torque transmitting element with the two halfCouplingSeparation to realize the protection of the main transmission system at both ends.on the one hand,CouplingIt is the stability of the coupling transmission and the service life of the coupling accessories.The dynamic balance of the coupling is a key issue that affects the transmission stability of the transmission system, the overall stability of the transmission system and the service life.CouplingThe damage state and service life of the accessory diaphragm are issues that need to be paid attention to. ".

通过 优化CouplingThe service life of the accessory and the service life of the coupling accessory can extend the service life and service life of the coupling accessory.The two halves of the ordinary cast iron coupling are easy to break,CouplingThe strength of the two halves of the coupling should match the overall strength performance of the transmission system. The mating strength of the coupling is the requirement of the nominal torque of the coupling, that is, the failure mode of the coupling should be the damage of the coupling accessory and the two halves of the coupling Basically intact, this kind of coupling is of good quality.The material form of the coupling can be divided into profiles, castings, forgings, etc., and cast steel and forgings are the choice of most coupling materials.

Profiles are generally smallCoupling, The commonly used coupling material form, should pay attention to quenching and tempering treatment when using, it is the key to improve the material performance, the choice of coupling material is directly related to the coupling performance.Cast steel is suitable for relatively large complexCouplingStructure, its coupling is often suitable for occasions with relatively large torque transmission, and also suitable for transmission systems under reciprocating impact loads.Therefore, even if cast steel is used because of the price of the coupling, the material composition and casting defects of the cast steel material are strictly controlled.Cast steel materials should be tempered accordingly. ".

Therefore, forging materials should be normalized at the same time to detect forging crack defects.CouplingThe quality is reflected in the entire process from coupling design to manufacturing.In the selectionCouplingPlease note that the rated torque is greater than the system load torque. The rated torque takes into account the operating load factor. When selecting the coupling size, please note that the load torque generated by continuous operation is lower than the rated torque.
