At present, hoisting machinery standards and industry standards include "Crane Design Specification" (GB/T3811-1983), "Lifting Machinery Regulations" (GB6067-1985, revised edition), etc., which have more than 200 items. The content of the standard mainly includes basics, products, hygiene, management and methods.
The quality requirements of the fan manufacturers also affect the operation of the fan, such as: poor parts processing and manufacturing, insufficient precision; poor parts material, insufficient strength, manufacturing defects; rotor dynamic balance does not meet the technical requirements, etc.
In a similar diaphragm rubber coupling structure, in order to minimize the reaction moment of each group of metal diaphragms under larger angular bending deformation, the two groups of metal diaphragms are set at both ends and expanded as much as possible. The spacing between the groups of diaphragms.
Due to manufacturing and installation errors, load-bearing deformation, thermal deformation, and sinking of the base, the two shafts connected by the plum blossom elastic coupling will have axial, angular, and radial deviations between the axes.
The inherent hazards that exist before the hoisting machinery is put into use are mainly divided into three stages. 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, and the operation of the shafting equipment.
