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.
Rigid couplings are commonly used in the connection of two shafts with good alignment, while quincunx couplings can provide two shafts with poor alignment. The important thing is that the elastic coupling can provide a flexible Link, this link can absorb the extra energy generated by the fluctuation of the shafting and external load.
Based on the deformation geometric relationship and force analysis of the coupling.According to the structure and characteristics of various types of couplings, the geometrical relationship and force of the misalignment are analyzed, and the expressions of the relationship between the generalized excitation force and the misalignment amount, speed and other parameters of the misalignment coupling are derived. On this basis, the differential equation of system porridge motion under the excitation force is obtained.
Improving the reform and innovation of the equipment structure by the operating unit, and carrying out on-the-spot operation guidance with innovative technology is an important means to increase the participation of bridge projects, and how to improve the efficiency of equipment operation has become the key.
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.
As a widely used type of crane, cranes can improve workshop productivity.As a large-scale lifting equipment, its internal structure is very complicated, which requires attention to daily inspection and maintenance work, to find problems in crane inspection, and to propose relevant countermeasures.
The fan and the motor are connected by a quincunx coupling to transmit movement and torque.Misalignment is a common failure of fans, and 60% of fan failures are related to misalignment.
In bridge engineering, bridge cranes mainly play a major role in the transportation of large and heavy tasks such as materials and materials.
