coupling 1614873900
It is the most commonly used connecting part in shafting transmission of mechanical products. Its function is to connect two axes to rotate together to transfer torque and motion, to compensate the relative displacement of the two axes connected and to improve the transfer dynamic characteristics of the system. Its application scope involves many fields of national economy, and it is a general basic component with many varieties and large usage. With the progress of science and technology and the development of production, the types of mechanical products are increasing day by day, and the requirements for their performance are also increasing. In order to meet the needs of different working conditions, the couplings with different characteristics are required, and the expected use effect has been obtained.
2) Load characteristics of coupling 1614873900
Between the power machine and the working machine, through a number of different forms or specifications of the coupling will be connected to the main, driven end, the formation of shafting transmission system, the mechanical characteristics of the power machine and the working machine (mechanical energy parameters T, P and the relationship between the corresponding motion parameters ω, t) has a significant impact on the whole transmission shafting. Engine, due to the different working principle and the structure will be made, including coupling transmission system on the load there is a big difference, so there is a serious impact load and long wave load, should choose to have buffer damping function coupling, in order to achieve peak load and torsional vibration cutting and adjust the system natural frequency, the purpose of preventing resonance.
3) Working speed of coupling 1614873900
The working speed of the coupling is directly related to the centrifugal force of each part of the coupling and the deformation of the elastic element. Excessive speed will lead to the increase of wear, deterioration of lubrication and loosening of the connection. The required speed range of the coupling is determined by calculation according to the linear speed and the maximum outer edge size allowed by the strength of different materials of the coupling. Different materials, varieties and specifications of the coupling of different allowable speed range, high precision in high speed should be chosen to balance the coupling, such as metal diaphragm coupling, coupling, etc., and non-metallic elastic element flexible coupling, unfavorable choose for high-speed non-metallic elastic element will produce larger non-working deformation.
4) Transmission accuracy of coupling
For precision transmission and servo transmission, it is required that the two shafts connected by the coupling should rotate synchronously in any case. Rigid coupling or metal diaphragm coupling should be selected. The transmission accuracy of most flexible couplings is lower than that of rigid couplings.
