HangzhouGICLZ type-drum gear coupling

GICLZ-Drum-shaped gear coupling drum-shaped tooth surface makes the contact condition of the inner and outer teeth, avoiding the disadvantages of spur tooth end edge extrusion and stress concentration under angular displacement conditions, and at the same time, the disadvantages of tooth surface friction, The wear condition reduces the noise and the maintenance cycle is long.The tooth end of the outer gear sleeve is in the shape of a horn, which makes the assembly and disassembly of the inner and outer gears convenient.

GICLZ type-drum gear coupling has good impact bearing performance, but the tooth surface contact stress and tooth root bending fatigue strength require high requirements. If we adopt structure, material and technology, then this coupling can meet the requirements of large diameter rolling pipe Machine requirements.With the development of China’s economy, the demand for large-diameter pipe rolling mills has increased, and the requirements for couplings used in the main drive have become higher and higher. Couplings that meet this requirement include cross universal couplings and large-torque drums. Gear couplings, the torque of the cross universal coupling can be reached, but the impact bearing performance is poor and the life is short, which is a big disadvantage; the current standard couplings used in domestic rolling mills cannot meet the requirements. Only 1/2 to 1/3 of the required transfer torque can be met by the coupling manufacturer. However, due to its special technology and the difficulty of manufacturing, the price is particularly expensive.A pipe rolling mill requires about 10 sets, and the cost of outsourcing spare parts is very high.Various drum-shaped gear couplings developed by our company according to customer needs have been able to meet the needs of domestic manufacturers.The drum gear coupling is a rigid-flex coupling. The gear coupling is composed of an internal 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 a general gear. Larger angular displacement (compared to spur gear couplings), the contact conditions of the teeth can be improved, the torque transmission capacity is improved, and the service life is prolonged.The contact state along the tooth width when there is an angular displacement.It has the ability to compensate for axis deviation in radial, axial and angular directions, and has the advantages of compact structure, small gyration radius, large carrying capacity, low transmission, low noise and long maintenance period. It is especially suitable for low-speed and heavy-duty conditions, such as metallurgy, It is also suitable for shafting transmission of various machinery such as petroleum, chemical industry, general machinery, etc. in mining, lifting and transportation industries.
