    Detailed introduction:

    The main purpose of the nylon sleeve inner gear ring is: forging, construction, mining, plastics, food, engineering, petroleum, chemical, machine tool, ship, leather, textile, fan, pump and other industries machinery transmission.The internal tooth type elastic nylon internal gear ring is superior to couplings with other structures. NL type nylon sleeve inner gear ring drum gear coupling is suitable for shaft and flexible transmission, allowing large axial radial displacement and angular displacement. It has simple structure, convenient maintenance, easy disassembly and assembly, and low noise. The loss of transmission efficiency is small, and the bench has the advantages of service life. The shaft hole types are cylindrical, conical and short cylindrical.The shaft hole and keyway are processed according to the standard GB3852-83 "Coupling shaft hole and keyway form and size", the working temperature is -20~+700℃, and the torque range is 40N.m~3150N.m.The nylon sleeve inner gear ring is composed of a flange half coupling with external teeth and an inner gear ring with the same number of teeth.The external teeth are divided into two types: drum teeth and straight teeth. The so-called drum-shaped nylon inner gear ring 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 ordinary gears. The inner gear ring coupling can allow a larger angular displacement (compared to the straight tooth coupling), the contact conditions of the teeth can be improved, the torque transmission capacity is improved, and the service life is prolonged.

    The nylon sleeve inner gear ring is suitable for the NL type drum gear coupling. Its product features are as follows:

    1. 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.Nylon sleeve inner gear ring is an accessory of drum gear coupling.

    2. 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, and the transmission reaches 99.7%;

    3. The drum-shaped tooth surface avoids the disadvantages of squeezing the edge of the straight tooth tooth under the condition of angular displacement and stress concentration. At the same time, the friction and wear conditions of the tooth surface reduce the noise and the maintenance cycle is long;

    4. Large angular displacement compensation: when the radial displacement is equal to zero, the allowable angular displacement of the spur gear coupling is 1o, while the allowable angular displacement of the drum gear coupling is 1o30, an increase of 50%;
