The coupling is a component that connects the two shafts axially and transmits torque and movement and has the ability to compensate for the offset of the two shafts. In order to reduce the vibration of the mechanical transmission system and reduce the impact spike load, the coupling should also have a certain buffering and shock absorption performance. The mechanical coupling malaysia sometimes also has the role of overload safety protection. The coupling is a link between two transmission components in the mechanical equipment, and is an important part of the industrial transmission.
Considerations for choosing a coupling
Mechanical characteristics of the power machine
Between the power machine and the work machine, through one or several different varieties of models, specifications of the coupling will be the main, driven end of the linkage, the formation of the shaft transmission system. Due to the different working principles and mechanisms of power machines, their mechanical characteristics vary greatly and have a varying impact on the transmission system. Different categories of power machines, due to their different mechanical characteristics, the corresponding power machine factor KW should be selected to choose the best coupling suitable for the system. The category of the power machine is the basic factor for selecting the coupling variety. The power of the power machine is one of the main bases for determining the coupling performance, which is proportional to the coupling torque.
The ability to correct deflection refers to the elasticity of the elastic coupling elastomer itself can withstand the radial, angular, axial recovery capacity. According to the precision and error of the connection between the machinery and the use of the occasion itself, the coupling with different corrective capacity is chosen to correct the mechanical error and to extend the service life of the motor and the screw or other transmission devices.
Due to different structures and materials, the load capacity of couplings used in the transmission system of various mechanical products varies greatly. The load category is mainly for the working load of the work machine of shock, vibration, forward and reverse rotation, braking, frequent starting and other reasons and the formation of different categories of load. The load category of the transmission system is the basic basis for selecting coupling varieties.
Permissible speed of the coupling
The permissible speed range of the coupling is determined by calculations based on the permissible linear speed and maximum outer edge size of the coupling in different materials. The permissible speed range for couplings of different materials, varieties and sizes is determined by calculation.
Couplings are used with a variety of different host products, the surrounding working environment is relatively complex, such as temperature, humidity, water, steam, dust, sand, oil, acid, alkali, corrosive media, salt water, radiation and other conditions, one of the important factors that must be considered when choosing a coupling. The environment is different, the coupling material chosen is also different.
