Evolution and performance of GCLD drum gear coupling

Publication time: November 2016, 06【L Small

    GCLD drum gear coupling allows larger angular displacement (compared to spur gear coupling), which can improve the contact conditions of the teeth and increase the ability to transmit torque. GCLD drum gear coupling is used in spur gears. Based on the coupling, a new type of gear coupling is developed through daily practice.The outer gear sleeve with spherical tooth thickness and the matching inner gear ring form the meshing connection of the two shafts, so that the contact conditions of the teeth are improved and the service life is prolonged.It is suitable for connecting two horizontal axis transmission shaft systems, and has the performance of compensating the relative deviation of the two shafts to a certain extent, and the transmission nominal torque is 710-1000000N.m.It has the advantages of compact structure, small radius of gyration, large carrying capacity, high transmission efficiency, low noise and long maintenance cycle. It has the ability to compensate for axis deviations such as radial, axial and angular axis, and heavy load conditions such as metallurgy, mining, It is also suitable for shafting transmission of various machinery such as petroleum, chemical industry, general machinery, etc. in industries such as lifting and transportation.

  When the GCLD 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 gear coupling needs to be Work in a good and sealed state.Under normal circumstances, it is required that the two shafts to be connected are completely concentric. It is impossible to continue to maintain the concentric state during the working process. Because of installation and production errors, bearing wear, force deformation, and foundation sinking, radial and Angular displacement. The GCLD drum gear coupling has the characteristics of compensating the above displacement, reduces the additional load caused by the shaft displacement, and improves the working stability and reliability of the transmission device.

  The GCLD drum gear coupling has the advantages of large transmission torque, strong ability to absorb coupling errors, and excellent durability. It is a common component for connecting two drive shafts in medium and heavy machinery.In engineering practice, due to manufacturing and installation errors, component deformation, wear, and foundation sinking, the position of the two axes will shift, resulting in axial displacement, radial displacement, angular displacement, and comprehensive displacement.The existence of offset causes additional dynamic loads on shafts, bearings, and couplings, causing vibrations and worsening the working conditions of machine parts.With the rapid development of modern industrial technology, more and more technical and economic indicators such as the carrying capacity, reliability, efficiency, circumferential speed, volume and weight of the drum gear coupling have been put forward.Drum gear couplings are developed on the basis of straight gear couplings to meet the technical requirements of large inclination angle, variable inclination angle, small size and high reliability.
