1. A kind of aligning type shaft coupling, including shaft coupling and pin, its characteristic is aligning type shaft coupling by the first shaft coupling (2), middle aligning (4) and second shaft coupling (5) to make up, wherein, one end of the first shaft coupling (2) is the first shaft base (2-2), another end of the first shaft coupling (2) is the first transmission fork (2-1), the space between two fork flaps of the first transmission fork (2-1) is the notch of the straight line shape, there are a pair of pin holes on the first transmission fork (2-1);

  • the middle aligning piece (4) is provided with a first aligning head (4-2) and a second transmission fork head (4-1), the first aligning head (4-2) and the second transmission fork head (4-1) are arranged on the same axis and face to each other, the first aligning head (4-2) is of a straight-line body structure, a first aligning hole (4-3) is formed in the first aligning head (4-2), the space between two fork lobes of the second transmission fork head (4-1) is a straight-line notch, the second transmission fork head (4-1) is provided with a pair of pin holes, and the straight-line body of the first aligning head (4-2) is perpendicular to the straight-line notch of the second transmission fork head (4-1);

    one end of the second coupling member (5) is provided with a second aligning head (5-1), the other end of the second coupling member (5) is provided with a second shaft seat (5-2), the second aligning head (5-1) is of a straight-line structure, and a second aligning hole (5-5) is formed in the second aligning head (5-1);

    a first aligning head (4-2) on the middle aligning piece (4) is inserted into a notch of a first transmission fork head (2-1) on the first coupling piece (2), and a first pin (3) passes through a first aligning hole (4-3) of the first aligning head (4-2) and is positioned in a pair of pin holes of the first transmission fork head (2-1);

    a second aligning head (5-1) on the second coupling piece (5) is inserted into a notch of a second transmission fork head (4-1) on the middle aligning piece (4), and a second pin (9) passes through a second aligning hole (5-5) of the second aligning head (5-1) and is positioned in a pair of pin holes of the second transmission fork head (4-1);

    the first pin (3) and the second pin (9) are vertical to each other, the first aligning hole (4-3) and the second aligning hole (5-5) are in a radial strip-shaped hole structure vertical to each other, and the moving direction of the first aligning hole (4-3) is vertical to that of the second aligning hole (5-5);

    the centering type coupler is used as a torque transmission part of a motor rotating shaft and a driven equipment rotating shaft, when radial displacement occurs between the two shafts, the first centering hole (4-3) or the second centering hole (5-5) performs corresponding radial movement to perform centering, and the first centering hole (4-3) and the second centering hole (5-5) which are perpendicular to each other perform automatic matching to adapt to radial movement in all directions, so that automatic centering is realized;

    when angular displacement occurs between the two shafts, the middle aligning piece (4) or the second coupling piece (5) performs corresponding angular adjustment by taking the first pin (3) or the second pin (9) as an axis, and the middle aligning piece (4) and the second coupling piece (5) perform automatic matching by taking the first pin (3) and the second pin (9) which are perpendicular to each other as axes respectively to adapt to the angular adjustment in each direction.
