Drum-shaped gear couplings have been heat-treated. Only in this way can they give play to their superiority, with better toughness and stronger wear resistance.Metal heat treatment is one of the important processes in mechanical manufacturing. Compared with other processing processes, heat treatment generally does not change the shape and overall chemical composition of the workpiece, but by changing the internal microstructure of the workpiece, or changing the chemical composition of the surface of the workpiece , To give or improve the performance of the workpiece.Its characteristic is to improve the internal quality of the workpiece, which is generally not visible to the naked eye. In order to make the metal workpiece have the required mechanical properties, physical properties and chemical properties, in addition to the reasonable selection of materials and various forming processes, the heat treatment process Is often essential.The drum gear coupling has the ability to compensate for axis deviations such as radial, axial and angular axis. It has the advantages of compact structure, small gyration radius, large carrying capacity, high transmission efficiency, low noise and long maintenance period. It is especially suitable for Low-speed and heavy-duty working conditions, such as metallurgy, mining, lifting and transportation industries, and also suitable for shafting transmission of various machinery such as petroleum, chemical industry, general machinery, etc. The drum gear coupling is a rigid-flexible coupling. The drum gear coupling is composed of an inner gear ring with the same number of teeth and a flange half coupling with external teeth.The external teeth are divided into straight teeth and drum teeth. The so-called drum teeth means that the external teeth are made into a spherical surface. The spherical surface is on the gear axis. The tooth side clearance is larger than that of ordinary gears. Drum-shaped gear couplings allow Larger angular displacement (compared to the straight tooth coupling) 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.When the drum gear coupling is working, the two shafts produce relative angular displacement, and the tooth surfaces of the internal and external teeth periodically slide relative to each other in the axial direction, which will inevitably cause tooth surface wear and power consumption. Therefore, the drum gear coupling requires Work in a good and sealed state.Drum-shaped 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. High-precision and dynamically balanced drum-shaped gear couplings can be used for high-speed transmissions, such as combustion engines. The shafting transmission of the steam turbine.Since the angular compensation of the drum gear coupling is greater than that of the straight drum gear coupling, drum gear couplings are widely used inside and outside. The straight drum gear coupling is an obsolete product. Try not to choose
