Introduce Demand curve of Drum gear coupling

      Drum gear coupling what are the requirements for the drum of curve? Non conjugate tooth surface of drum tooth surface is composed of different end section gradually phase stacked, the dotted line quality formation and axial coordinates curve called drum, drum curve is an important geometric parameters of drum type gear coupling.
    Crowning curve is a circular arc, are also useful for three sections of circular arc, the circle is called circular arc drum drum, the drum of curve, circle center of the gear axis, not in the axis of the drum; a circular center and the tooth surface spherical center of coincidence, there are do not coincide, usually the design is based on the experiences, in general, Ling Si drum gear coupling should meet the following requirements:

Fluid Couplings

    1.In the shaft angle is the maximum does not appear when the edge contact phenomena;
    2.The tooth concentrated load smaller is better, and the tooth surface curvature and the drum is proportional to the degree of PI, therefore bulge radius is as large as possible.
    Crowning curve radius of curvature and the internal gear unilateral reduction Bo Liangcheng proportional, therefore bulge radius should be as large as possible.
     Crowning curve radius of curvature and the internal gear unilateral reduction is proportional to the Bo Liangcheng, that it is related with the meshing clearance of tooth, thinning volume may cause interference, thinning will weaken the strength of tooth, and the backlash of great.
