The first is the selection phase of the crane. The parameters of the hoisting machinery are the indicators of the working performance of the hoisting machinery and the basis for the design. The basis of which type of lifting equipment is used in the operation.
When the crane is working, the misalignment of the coupling between the reducer and the motor of the hoisting mechanism and the luffing mechanism, or the shaft between the two due to excessive installation errors, will cause the vibration of the machine, the wear of the bearing and the shaft Deflection and deformation will cause the high-speed shaft of the reducer to break in serious cases, which poses a great threat to the normal operation of the system. From the recent several accidents of the crane reducer shaft broken, it may be caused by such factors. of.
Because the shaft of the induced draft fan and the motor are not concentric, or there is no gap between the induced draft fan and the motor coupling, it will also cause severe vibration of the bearing seat and the motor.
The elastic coupling can compensate for the axial offset, radial offset or angular offset of the shafting axis during operation to ensure the operation of the shafting equipment.
There are relatively many types of cable reels, and the more common ones are counterweight, hysteresis, frequency conversion, torque, etc.
Due to bearing misalignment, the load distribution of each bearing and the dynamic characteristics of the bearing change, which affects the stability of the entire rotor-bearing system;
As a key component for carrying wind wheels and generators, gearboxes work under severe conditions of variable speed and load for a long time. The vibration signals generated by plum-shaped elastic couplings mostly contain Gaussian noise, and have non-stationary and non-linear characteristics. The faults that occurred include: gear damage, bearing damage, oil leakage, broken shaft, poor lubrication, shaft misalignment, shaft imbalance, high oil temperature, etc.
