GIICL type drum gear coupling

Brief introduction of GIICLZ drum gear coupling:

    GIICL narrow drum gear coupling.Gear coupling is composed of internal gear ring with the same number of teeth and 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 center of the spherical surface is on the gear axis. The tooth side clearance is larger than that of ordinary gears. Allows a larger angular displacement (compared to the straight tooth coupling), which can improve the contact conditions of the teeth, increase the torque transmission capacity, and prolong the service life.

    GIICLZ type drum gear coupling has a certain angular compensation performance of the relative deviation of the two shafts, plus the intermediate shaft for long-distance work, the working environment temperature is -20-+80℃, and the transmission nominal torque is 0.4-4500Kn.m.The German Lingsi GCLZ drum gear coupling is suitable for connecting two horizontal coaxial lines and a transmission shaft system with a certain angular displacement!German Lingsi GIICLZ type drum gear coupling has small radial size and large load capacity. It is often used for shaft transmission under low speed and heavy load conditions. High precision and dynamically balanced gear coupling can be used for high speed transmission. , Such as the shaft drive of a gas turbine.The German Lingsi GCL, GCLZ drum gear coupling is suitable for connecting two horizontal coaxial lines with a certain angular displacement of the transmission shaft system. When the two shaft ends are far apart, the GCLZ type is suitable!The characteristics of the German Lingsi GCL drum gear coupling (compared with the straight gear coupling, it has the following characteristics)

  Characteristics of drum gear coupling:

   Drum-shaped gear coupling is attributed to rigid-flexible coupling: Drum-shaped gear coupling is attributed to rigid-flexible coupling. Compared with gear couplings, it has the advantages of exquisite design, small reversal spread radius, large load-bearing force, high transmission efficiency, low noise and long maintenance period. It is especially suitable for low-speed and heavy-duty occasions, such as metallurgy, mining, and lifting It is also suitable for shaft transmission of various machines such as alcohol, chemical industry and general machinery.The characteristics of the drum gear coupling (compared with the straight gear coupling, it has the following characteristics)
   1. Strong carrying capacity.Under the opposite outer diameter of the inner gear sleeve and the larger outer diameter of the coupling, the load-bearing force of the drum gear coupling is evenly increased by 15-20% than that of the straight gear coupling;
   2. The angular displacement compensation is large.When the radial displacement is zero, the allowable angular displacement of the spur gear coupling is 1ordm; and the allowable angular displacement of the drum gear coupling is 1ordm; 30”, an increase of 50%, in the opposite Under the modulus, number of teeth, and tooth width, the angular displacement of the drum-shaped gear is larger than that of the straight tooth;
   3. The drum-shaped tooth surface makes the contact environment of the inner and outer teeth lose improvement, prevents the edge of the straight tooth tooth from squeezing and stress collection under the angular displacement environment, and at the same time improves the conflict and wear of the tooth surface. Noise, long maintenance period;
   4. The tooth end of the outer gear sleeve is in the shape of a speaker, which makes the assembly and disassembly of the inner and outer gears very convenient.
   5. The transmission efficiency is as high as 997%.Based on the characteristics of warp, at present, drum gears have been widely used in the industry to replace straight gear couplings.
       The drum-shaped gear coupling produced by UMA has complete types and specifications, and meets the corresponding requirements.Drum-shaped gear couplings are rigid, flexible, and inelastic, so they are not suitable for standard vibration reduction, buffering, and two-axis alignment machines with strict standards.Definition of gear coupling The gear coupling is composed of a complete machine such as an internal gear ring with opposite numbers of teeth and a flange half coupling with external teeth.The external teeth are divided into two types of teeth, straight teeth and drum teeth. The drum teeth are called spherical teeth. The core of the spherical surface is on the axis of the cone. The tooth side clearance is larger than that of the normal cone. Drum tooth coupling Allows for larger angular displacements (absolutely in spur gear couplings), can improve the contact environment of the teeth, increase the transmission torque, and extend the use time

Professional standards for drum gear couplings were formulated in the XNUMXs in my country:

    ZBJ19012-89,ZBJ19013-89，ZBJ19014-89，现在修订为：JB/T8854.1-2001，JB/T8854.2-2001，JB/T8854.3-2001;其回转直径1644mm;公称转矩       4500kN.m。

   齿面曲率半径和齿啮合角直接影响接触应力,啮合角小曲率半径大,曲率半径大则接触应力小。在国外鼓形齿式联轴器的啮合角有20°、21.5°、28°、30°。我     们选用20°啮合角，有利降低接触应力。

   The shaft sleeve tooth profile processing of the drum gear coupling, from the manual, electric pulse, hydraulic profiling to the comprehensive numerical control processing in China, the accuracy can fully meet the design requirements.Nitriding treatment can be carried out when hard tooth surface is required, or high-quality low-carbon alloy steel can be used for carburizing and quenching and grinding or scraping with an alloy knife to meet the design requirements.
