Nylon sleeve inner gear ring

Nylon sleeve inner gear ringIt belongs to a rigid-flexible 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 the general gear. Larger angular displacement (compared to spur gear coupling), the contact condition of the teeth can be improved, the ability of transmitting torque 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. It has the advantages of compact structure, small turning radius, large carrying capacity, high transmission efficiency, low noise and long maintenance cycle. It is especially suitable for low speed and heavy load conditions, such Metallurgy, mining, lifting and transportation industries, and also suitable for shafting transmission of various machinery such as petroleum, chemical industry, general machinery and so on.

The characteristics of drum gear couplings (compared to straight gear couplings with the following characteristics):

1. Strong carrying capacity.Under the same outer diameter of the inner gear sleeve and the 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 gear is larger than that of the straight tooth.

3. The drum-shaped tooth surface makes the contact conditions of the inner and outer teeth avoid the disadvantages of squeezing the edge of the straight tooth and stress concentration under the condition of angular displacement. At the same time, it reduces the friction and wear of the tooth surface, reduces noise, and maintains The cycle is long.

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. High transmission efficiency.
