Do you know the advantages of WGT-connected middle sleeve gear coupling?

After carburizing and quenching, the drum tooth surface has a high bearing capacity. The main failure form of the drum tooth is wear. After forced thin oil lubrication, the tooth surface wear is reduced, and the wear amount is about 10 of the lubricating grease lubrication amount, and the circulating thin oil can be taken away The heat generated by the rolling heat of the roller end and the friction force of the gear teeth prevents the contact stress on the surface of the gear tooth material from being reduced.Under normal circumstances, there will be no tooth breakage, which can meet the working characteristics of continuous rolling mills.The use of WGT type gear coupling with intermediate sleeve can meet the requirements of rolling mill rolls, and the expansion is very convenient.It is stable, clean, and so on.

1. The contact conditions of the teeth can be improved

The external teeth of the WGT type intermediate sleeve gear coupling are divided into two types of teeth, straight teeth and drum teeth. The WGT type intermediate sleeve gear coupling can allow a larger angular displacement (relative to the straight tooth coupling ), which can improve the contact conditions of the teeth, increase the torque transmission capacity, and prolong the service life.The contact state along the tooth width when there is angular displacement.

WGT type intermediate sleeve gear coupling has radial, axial and angular axis deviation compensation capabilities. It has the advantages of compact structure, small gyration radius, large carrying capacity, low transmission, low noise and long maintenance cycle.When the drum gear coupling is working, therefore, the gear coupling needs to work in a good and sealed state.

Gear couplings have small radial dimensions and large load-bearing capacity. They are often used in shaft transmissions under low-speed and heavy-duty conditions. The dynamically balanced gear couplings can be used for high-speed transmissions, such as gas turbine shaft transmissions.Since the angular compensation of WGT-connected middle sleeve gear couplings is greater than that of straight-tooth couplings, Lingsi WGT-connected middle sleeve gear couplings are widely used.Drum-type gear couplings are rigid-flexible couplings.

2. Absorb the connection error

Among the various types of couplings, the WGT-type intermediate sleeve gear coupling has the advantages of small size, large transmission torque, strong absorption of coupling errors, and good performance.In engineering practice, due to manufacturing and installation errors, component deformation, wear, foundation sinking, etc., the axis position of the two shafts will be offset, axial displacement, radial displacement, angular displacement and comprehensive displacement will occur. .The existence of misalignment causes additional dynamic loads on shafts, bearings, and couplings, causing vibrations and making machine parts work poorly.

With the development of modern industrial technology, the requirements for the load-carrying capacity, performance, efficiency, peripheral speed, volume and weight of WGT-type intermediate sleeve gear couplings are getting higher and higher.On the basis of the spur gear coupling, the WGT type coupling with intermediate sleeve gear is developed to meet the requirements of large inclination angle, large inclination angle, small size and high performance.The structure of the WGT-type intermediate socket coupling is basically symmetrical.The teeth on the outer gear sleeve in the tooth tip direction are bulge teeth, and the tooth thickness gradually decreases from the middle to the two sides. The teeth on the ring gear that mesh with the teeth are straight teeth.The tooth top and tooth surface of the external gear shaft are curved, and the entire coupling is a double-joint flexible coupling, which can adjust the large deflection angle between the two shafts.In production practice, the WGT-type intermediate sleeve gear coupling plays an important role.It can compensate the angular error, axial installation error and radial installation error caused by the two coupling shafts not being reunited, so that the two shafts have a specific displacement.
