Derivative axial force of diaphragm couplings
Thread Content
Hello everyone, the equipment I’m working with uses a dual-mode coupling to connect the motor shaft to the driven shaft. The equipment is installed vertically. There is a force sensor on the motive base, which detects a significant axial force; this additional axial force increases as the transmitted torque increases. I’m really puzzled as to where this additional axial force comes from; logically, the axial stiffness of a dual-mode plate coupling should be very low. I would like to ask everyone: 1. Apart from angular misalignment, under what circumstances can an additional axial force occur in a dual-mode plate coupling? 2. Will additional axial force be generated after the diaphragm itself undergoes torsional deformation?
““The axial stiffness of a dual-mode plate coupling should be very low,” but this is relative, and there is still a certain range; values outside this range are not acceptable. It is recommended to focus on reducing this \"very low\" value; the alignment of the equipment, its levelness/verticality, as well as the parallelism of the coupler openings and the gaps involved should all be kept at the minimum levels specified in the standards.
Are there any requirements regarding the distance between the equipment installation and the wheel end face? Should the distance be larger or smaller?
Should the seniors on the 4th floor do more analysis and provide more information on couplings?
If the gap is too large or too small, it will cause the driver and the driven to affect each other!
