Brake disc coupling

  Brief introduction of various types of brake wheel plum blossom couplings:

    MLL-I type brake wheel plum-shaped elastic coupling is suitable for the rotation of two concentric shafts in various mechanical connections. It has a large compensation for the relative deviation of the two shafts, buffering, shock absorption, oil resistance, air aging resistance, wear resistance, etc. Performance, reasonable structure, convenient maintenance, few parts, strong adaptability and long service life.

    The MLL-Ⅱ integral brake wheel type plum blossom elastic coupling is composed of two half couplings with the same shape of the claws and elastic elements. The plum blossom elastic element is used to place between the two halves of the coupling claws. , In order to realize the connection of the two halves of the coupling.It has the characteristics of compensating the relative offset of the two shafts, damping, buffering, small radial size, simple structure, no lubrication, high carrying capacity, convenient maintenance, etc. However, the two halves of the coupling must be moved in the axial direction when replacing the elastic element.

    LMZ-I split brake wheel type quincunx elastic coupling is composed of two half-couplings with the same shape of the claws, brake wheel and elastic elements. The quincunx elastic element is used to place the two halves of the coupling. Between the two halves of the coupling.

    LMZ-Ⅱ (formerly MLL-Ⅱ) type integral brake wheel type plum blossom elastic coupling is connected by a half coupling with a claw and a half coupling with a brake wheel with a claw, and flange connection It is composed of two parts and elastic elements. The plum-shaped elastic element is placed between the two halves of the coupling claw to realize the connection of the two halves of the coupling.

    Structural features of plum-shaped elastic coupling:

    The quincunx-shaped elastic coupling is composed of two half-couplings with the same shape of the claws and elastic elements. The quincunx-shaped elastic element is placed between the two halves of the coupling claws to realize the coupling of the two halves. Join.
    It has the characteristics of compensating for the relative offset of the two shafts, damping, buffering, small radial size, simple structure, no lubrication, high carrying capacity, and convenient maintenance. However, the two halves of the coupling must be moved in the axial direction when replacing the elastic element.It is suitable for connecting two coaxial lines, frequent starting, forward and reverse changes, medium and low speed, medium and small power transmission shaft systems, and working occasions that require high work reliability. It is not suitable for heavy loads and limited axial dimensions, and after replacing elastic components Where it is difficult to align the two axes.

    Features of drum gear coupling:
    The drum gear coupling has strong load-bearing capacity and high transmission efficiency. Under the same outer diameter of the inner gear sleeve and larger outer diameter of the coupling, the load-bearing capacity of the drum gear coupling is on average than that of the straight gear coupling. The transmission efficiency of the drum gear coupling is as high as 15%.The angular displacement compensation of the drum-shaped gear coupling is large.When the radial displacement is equal to zero, the allowable angular displacement of the spur gear coupling is 20o, and the allowable angular displacement of the drum gear coupling is 99.7o1', an increase of 1%.Under the same modulus, number of teeth, and width of the drum-shaped gear coupling, the allowable angular displacement of the drum-shaped gear is larger than that of the straight tooth. The drum-shaped tooth surface improves the contact conditions of the inner and outer teeth and avoids the angle Under the condition of displacement, the edge of the straight tooth tooth end is squeezed and the stress is concentrated. At the same time, it improves the friction and wear of the tooth surface, reduces the noise, and has a long maintenance period. The disassembly is very convenient. The drum gear coupling is a rigid-flex coupling. The gear coupling is composed of an inner 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 center of the spherical surface is on the gear axis. The tooth side clearance is larger than that of ordinary gears. The drum-shaped gear coupling can 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.The contact state along the tooth width when there is 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 period. It is especially suitable for low-speed and heavy-duty conditions, such as When the shaft drive drum gear coupling of metallurgy, mining, lifting and transportation industries, and also suitable for various machinery such as petroleum, chemical industry, general machinery, etc., when working, the two shafts produce relative angular displacement, and the tooth surfaces of the internal and external teeth Periodic relative sliding in the axial direction will inevitably cause tooth surface wear and power consumption. Therefore, the gear coupling must work in a good and sealed state.
