Comparison of new and old processing couplings Shanghai Nuoguang Professional

Couplings belong to the category of general mechanical parts and are used to connect two shafts (drive shaft and driven shaft) in different mechanisms to rotate together to transmit torque. In high-speed and heavy-load power transmission, some couplings also play the role of buffering, vibration reduction and improving the dynamic performance of the shaft system. The coupling consists of two halves that are connected to the driving shaft and the driven shaft respectively. Generally, most power machines are connected to working machines by means of couplings, which are the most commonly used connecting components for shaft transmission of mechanical products. In the late 20th century, coupling products at home and abroad developed rapidly. When designing products, how to choose a coupling that can meet the requirements of the machine from a wide variety of couplings with different performances has always been a problem for most designers. The problem. Commonly used couplings include diaphragm couplings, gear couplings, plum blossom couplings, slider couplings, drum gear couplings, universal couplings, safety couplings, elastic couplings and serpentine spring couplings. device. Correctly choosing a good coupling that suits your needs among many standard couplings is related to the working performance, reliability, service life, vibration, noise, energy saving, transmission efficiency, transmission accuracy, economy, etc. of the shaft system transmission of mechanical products. A series of issues are also related to the quality of mechanical products.
Coupling working environment requirements:
The working environment around the coupling and various host products is relatively complex. Conditions such as temperature, humidity, water, steam, dust, sand, oil, acid, alkali, corrosive media, salt water, radiation, etc. are one of the important factors that must be considered when selecting a coupling. For working environments with high temperature, low temperature, oil, acid, and alkali media, it is not advisable to choose flexible couplings with ordinary rubber as the elastic element material. Flexible couplings with metal elastic elements should be selected. The elastic pin gear coupling makes a lot of noise due to the movement of the pin during operation, so it should not be used in occasions with strict noise requirements.
