Technical Field

[0002] Couplings are generally divided into rigid couplings and flexible couplings. They are usually composed of two parts, which are connected by keys or tight fits, fastened to the two ends of the shaft, and then connected by rigidity and elasticity. At present, there are more flexible couplings on the market. Flexible couplings can be divided into flexible couplings without elastic elements and flexible couplings with elastic elements. Flexible couplings without elastic elements have the ability to compensate for the relative displacement of the two axes and can adapt to the two axes not being in the same plane, but cannot buffer and reduce shock. Flexible couplings with elastic elements can achieve buffering and shock reduction, but cannot withstand large loads. Therefore, it is urgent to design a coupling that can compensate for the relative displacement of the two axes, buffer and reduce shock, withstand large loads, and is convenient and practical to meet current needs.

[0020] The included angle is an acute angle.

[0021] The connection parts between the left claw plate 1 and the right claw plate 2 and the main shaft are both provided with internal splines to increase the connection stability and improve the load-bearing capacity.

[0022] A method for using an arc-shaped convex tooth coupling, using the arc-shaped convex tooth coupling, comprising the following steps: each right claw plate convex tooth 201 is arranged in the space between two adjacent left claw plate convex teeth 101, each left claw plate convex tooth 101 is arranged in the space between two adjacent right claw plate convex teeth 201, and there is a gap between the left claw plate convex teeth 101 and the right claw plate convex teeth 201, the left claw plate convex teeth 101 on the left claw plate 1 and the right claw plate convex teeth 201 on the right claw plate 2 are meshed; both sides of the left claw plate convex teeth and the right claw plate convex teeth are arc-shaped structures, and when the left claw plate convex teeth and the right claw plate convex teeth are in meshing contact, Since there are more contact points on the tooth surface, the contact stress generated between the gears is smaller, so the contact process is relatively smooth, which plays a role in buffering and shock absorption, and smoothly compensates for the relative displacement between the two axes; after a period of running-in, the contact area between the left claw plate convex teeth and the right claw plate convex teeth becomes larger, the contact stress gradually decreases, the contact strength increases, and the load-bearing capacity also increases accordingly; an oil filling hole 202 is provided on the right claw plate convex teeth, and the oil enters the arc groove 204 through the oil filling hole 202, and flows to both sides along the arc groove to reach the left claw plate convex teeth 101 and the right claw plate convex teeth 201 during work, which plays a protective role.

[0023] In this embodiment, the left claw disk 1 is provided with four left claw disk convex teeth 101, and the four left claw disk convex teeth 101 are distributed at 90 degrees. The two side surfaces of each left claw disk convex tooth 101 adopt an arc structure, and buffering and shock absorption are achieved by increasing the contact points, and the relative displacement of the two axes is compensated; each right claw disk convex tooth 201 is arranged in the space between two adjacent left claw disk convex teeth 101, and a gap is left between the two adjacent left claw disk convex teeth 101, which is convenient for meshing; the right claw disk 2 is provided with four right claw disk convex teeth 201, and the four right claw disk convex teeth 201 are distributed at 90 degrees.

When the left claw disc convex teeth 101 and the right claw disc convex teeth 201 are in meshing contact, due to the large number of tooth surface contact points, the contact stress generated between the gears is small, so the contact process is relatively gentle, which plays a role of buffering and shock absorption, and steadily compensates for the relative displacement between the two axes; after a period of running-in, the contact area between the left claw disc convex teeth 101 and the right claw disc convex teeth 201 becomes larger, the contact stress gradually decreases, the contact strength increases, and the load bearing capacity also increases accordingly.
