XINLAN removable rigid coupling and its characteristics

Removable rigidCouplingIt is movable and can compensate the offset between the two axes.
        1. Cross slider coupling
         It is composed of two semi-couplings with grooves and a disc with mutually perpendicular teeth on both ends.
        Commonly used material: No. 45 steel, the working surface is heat-treated
        It is suitable for occasions where the speed n is less than 250rpm and the shaft rigidity is large.
        2. Slider coupling
        Change the slider to a square, made of nylon or bakelite.
        Suitable for low power, speed, violent rushing
        3. Universal coupling
        Suitable for low speed
        It consists of two fork joints and cross heads.
        Single universal coupling When the driving shaft rotates at a constant speed, the driven shaft is rotating periodically at a variable speed. For this reason, a double universal coupling is used to ensure that the driven shaft and the driving shaft rotate at equal angular speed. The condition is intermediate The two meanings of the shaft are in the same plane.
       Material: Alloy steel, heat treatment improves wear resistance.
       Features: Allow the two shafts to have a larger angle α up to 35°～43°, and the angle change when the machine is running does not affect the transmission, and the structure is simple and easy to maintain.
       It is suitable for automobiles, tractors, multi-head drilling machines, hydraulic transmission locomotives, and generators.
      4. Gear coupling
      It is composed of two sleeves with internal teeth and flanges and two internal sleeves with external teeth, and the torque is transmitted by the meshing of the internal and external teeth.
      The tooth top of the external tooth is made into an ellipsoidal surface with a large gap on the side of the tooth top.
      材料：45号钢或 tG45   采用渐开线齿形，α＝20°，t＝30～80。
      Features: can transmit a large torque.
      The installation accuracy is not high, and the parts have a large comprehensive displacement.
      It is widely used in heavy machinery rolling mills, worm gears, output shafts of gearboxes, and steam turbine generators, and has been standardized.
