Z11 type expansion joint sleeveCompared with the Z11 type, the Z2 type expansion coupling sleeve has a long joint surface and high centering accuracy. It is used for rotation accuracy...The serpentine spring coupling is a metallic coupling with a structure that relies on the serpentine spring to axially embed the two halves of the coupling by more than 36%. The trapezoidal section of the serpentine spring is made of high spring steel, which has undergone strict heat treatment. Processed with good mechanical properties, thus
After carburizing and quenching treatment of drum-shaped tooth meshing tooth surface, the bearing capacity is high; the main failure mode of drum-shaped tooth is wear. After using forced thin oil lubrication, the tooth surface wear is greatly reduced, and the amount of wear is 10% of grease lubrication. Around XNUMX, the circulating thin oil can take away the rolling heat at the end of the roll
The coupling of the wind generator is mainly to transmit power, but the transmission accuracy must be relatively high.During this period, not only must avoid non-metal elastic elements, but also avoid gaps between movable elements.Under this condition, the high-speed rotation process is prevented, and the coupling is prevented from being damaged.
Because different couplings have different load bearing capacities, the load that the plum-blossom flexible coupling on the wind turbine generator bears is mainly affected by the impeller, gearbox and generator.If the coupling is affected by its own center of mass and inertia, the unbalanced state of centrifugal inertia will also occur during operation.
Rotor misalignment usually refers to the degree of inclination or deviation between the axis centers of two adjacent rotors and the center lines of the bearings.Rotor misalignment can be divided into coupling misalignment and bearing misalignment.
Plum-shaped flexible couplings are in my country, and the capacity of wind turbines ranges from 500KW to 5MW. The mainstream models on the domestic market are 1.5MW. Most of the more than 2MW are under development, and a small number of 4MW and 5MW models are in use. In trial operation.
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.
Plum-shaped flexible couplings are being built vigorously as an important part of road traffic under the background of rapid economic and social development in my country.
