The initially selected coupling size, that is, the shaft hole diameter d and the shaft hole length L, should meet the requirements of the main and driven end shaft diameters, otherwise the coupling specifications must be adjusted according to the shaft diameter d.It is a common phenomenon that the shaft diameters of the driving and driven ends are different. When the torque and speed are the same,...
Due to various reasons, the center of mass or inertial principal axis of the coupling does not coincide with the axis of rotation, and the phenomenon of unbalanced centrifugal inertial force, centrifugal inertial couple force and dynamic deflection (vibration shape) will be generated during operation, which is called the unbalance of the rotor. Phenomenon, this imbalance must...
The Oldham coupling is composed of two shaft sleeves and a central slider.The center slider is usually made of engineering plastic as a torque transmission element, and other materials, such as metal materials, can be selected under special circumstances.The center slider is 90°relatively distributed through both sides...
In the elastic pin coupling standard, the allowable compensation amount refers to the relative allowable deviation of the two shafts due to factors such as installation error, shock, vibration, deformation, and temperature changes.Then the value given by the allowable compensation amount is: Axial Δχ0.5mm～3mm, radial Δ...
The smelting of casting alloys is an indispensable process in the production process of castings, also called smelting process, which is a fundamental factor that determines the quality and cost of castings.Many performance indicators of castings are largely determined by the chemical composition, temperature and purity of the molten metal...
There are many types, types and specifications of couplings. Among the many standard couplings, the correct choice of the best coupling that suits your needs is related to the working performance, reliability, and service life of the shaft transmission of mechanical products. Vibration, noise, energy saving, transmission...
