What Are the Performance Requirements for the Use of Flexible Couplings?

During the use of elastic couplings, it is necessary to select appropriate flexible couplingsbased on actual performance requirements to ensure their correct use.

1. To facilitate a complete understanding of the transmission system where the flexible  coupling is located, users should provide the following technical information when using it: description and diagram of the machine and equipment like driving machinery, driven machinery, and auxiliary machinery; Transmission ratio of the system; Moment of inertia of rotating parts, inertia elasticity data of the whole system, all dimensional limits; The limit size of loading and unloading space, the working state of the connected shaft, and balance requirements; The nominal axial distance between shafts or flanges, providing detailed dimensions and tolerances of the connected shaft or flange as much as possible, and the maximum cantilever load on each shaft; The distance from the closest bearing to the coupling and the type of bearing, as well as the maximum axial load of the drive and driven shafts.

2. The power of the transmitted speed, including the speed and nominal torque at which the speed torque curve operates normally. Maximum allowable speed and torque; Please specify the range of instantaneous or continuous frequency changes, as well as the instantaneous load during acceleration or deceleration. The required lifespan and allowable maintenance time for the working state (continuous, intermittent, oscillating, and forward and backward rotation, etc.). Environmental data for transportation, storage, and use: impact and vibration, environmental temperature and humidity range, presence of oils, solvents, corrosive liquids, vapors, sand, dust, saline water, and radiation. The expected offset between the connected shafts: the general and maximum allowable offsets in angular, radial, and axial directions during operation, as well as the general and maximum allowable offsets during operation and parking. The impact of temperature changes. Performance requirements for couplings: torsional stiffness; Axial stiffness, critical speed of intermediate shaft coupling, etc
