How to reduce the loosening of coupling bolts?
The coupling is to firmly connect the driving shaft and the driven shaft of the equipment and rotate together. If the coupling bolts are loose or slip out, it will affect the normal operation of the mechanical equipment. What impact will the loose coupling bolts cause? ?
There are three ways for coupling to transmit torque, bolt transmission, coupling surface friction transmission, both of them, and couplings belong to both transmission methods. In the transmission process, each bolt torque should be It is uniform, so that in the process of load change, the force transmitted by each bolt also increases or decreases equally.
In the coupling industry, the coupling is often damaged prematurely due to the loosening of the fasteners, which leads to major economic losses. Therefore, the coupling manufacturers will choose the appropriate fastener locking method for them. This is a couplet. A major measure for long-term, reliable and trouble-free operation of the shaft unit. When the coupling is loose, it may cause uneven transmission torque and cause vibration to change with load.
There are only two bolts in the coupling. If the shear force of the female bolt is equal, only torque exists in the coupling. If the shear force of the two bolts is unequal, there is a force acting on the center of the rotor in addition to the torque. , This F changes with the load of the unit, so the vibration of the unit also changes as the load changes.Except for F, the loosening of bolts will cause the position of the two halves of the pair of wheels to change, the center of mass of the coupling will deviate, and a new additional unbalanced mass will appear, resulting in additional unbalanced force, which is manifested as a sudden rise in vibration.The misalignment of the opposite wheel changes with the load change, so the unit vibration XNUMX also appears as a sudden rise with the load change.
We must pay attention to the loosening of coupling bolts, and in the process of purchasing couplings, we must pay attention to whether the locking method adopted by the coupling manufacturer is appropriate, like the nuts used on the diaphragm coupling, generally use locking At the same time, pay more attention to the installation and use process, so as to reduce the loosening of coupling bolts!
