GⅡCLZ type-drum gear coupling

Due to the drum toothCouplingAngular compensation is greater than straight gear couplings. Drum gear couplings are widely used at home and abroad. Straight gear couplings are obsolete products, and users should try not to choose them.

  GⅡCLZ type-drum shapeToothedCouplingDuring operation, the two shafts produce relative angular displacement, and the tooth surfaces of the inner and outer teeth periodically slide relative to each other in the axial direction, which results in tooth surface wear and power consumption. Therefore, the gear coupling needs to work in a good and sealed state. .
Gear couplingThe radial size is small and the load capacity is large. It is often used for shafting transmission under low-speed and heavy-duty conditions. The high and dynamically balanced gear coupling can be used for high-speed transmission, such as the shafting transmission of gas turbines.Since the angular compensation of drum gear couplings is greater than that of straight gear couplings, drum gear couplings are widely used at home and abroad. Straight gear couplings are obsolete products, and those who choose should try not to use them. .

Type I-The sealed end is a separate type, with a large tooth spacing, allowing a large radial displacement, and can be connected with Y, JXNUMX, and ZXNUMX shaft extensions.

Type Ⅱ-The sealing end is integral, with small tooth spacing, relatively small radial displacement, compact structure, small moment of inertia, and can be connected with Y and JXNUMX shaft extensions.

Main features (compared with straight gear couplings, it has the following features):

1. Strong carrying capacity.Under the same outer diameter of the inner gear sleeve and the large outer diameter of the coupling, the carrying capacity of the drum gear coupling is on average 15-20% higher than that of the straight gear coupling.

2. Large angular displacement compensation.When the radial displacement is equal to zero, the allowable angular displacement of the spur gear coupling is 1o, and the allowable angular displacement of the drum gear coupling is 1o30', an increase of 50%.Under the same modulus, number of teeth, and tooth width, the allowable angular displacement of the drum tooth is larger than that of the straight tooth.

3. The drum-shaped tooth surface improves the contact conditions of the inner and outer teeth, avoids the disadvantages of squeeze the edge of the straight tooth and stress concentration under the condition of angular displacement, and at the same time improves the friction and wear of the tooth surface, and reduces the noise , Long maintenance cycle.

4. 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 teeth very convenient.

5. The transmission efficiency is as high as 99.7.

Based on the above characteristics, at present, drum-shaped gears have generally been substituted for straight-tooth couplings at home and abroad.
