Z5 type expansion joint sleeveThe Z5 type expansion coupling sleeve is used for the occasions that transfer large loads and require high centering accuracy.versus...The quincunx-shaped elastic coupling is mainly composed of two protruding teeth that are closely meshed and subjected to radial compression to transmit torque. When the two axes are relatively offset, the elastic element undergoes corresponding elastic deformation, which plays a role of automatic compensation.Plum-shaped elastic coupling is mainly suitable for frequent starting
The requirement for the exchangeability of the essential parts of the drum gear coupling is worthy of our attention: the parts of each specification of the drum gear coupling can be exchanged. If one of them is damaged, it can be replaced with a single spare part. All are changed, which saves maintenance time and is convenient for use
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 plum blossom elastic coupling has the ability to compensate, and is suitable for working conditions where there is an offset between the two axes, and has cushioning and shock absorption properties.The coupling does not need to be lubricated and can work in dusty and humid conditions. The structure is simple and the maintenance is convenient. However, it needs to be moved when changing the elastic element.
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.
