Embodiment 1

[0023] The present invention proposes an elastic coupling, which includes a first half coupling, a second half coupling and an elastic component, wherein one end of the elastic component is fixedly connected to the first half coupling, and the other end is connected to the second half coupling. The shaft is fixedly connected.

[0024] like figure 1 As shown, the elastic component in this embodiment is a twisted steel wire rope 4, and its two ends are fixedly connected with the first half coupling 1 and the second half coupling 5 respectively. The twisted steel wire ropes 4 are arranged at least once in the circumferential direction, and the twisted steel wire ropes 4 arranged in the same circle are parallel to each other. If the arrangement of twisted steel wire ropes is more than two turns, the twisted steel wire ropes of two adjacent turns are arranged at an angle, and the value range of the formed angle β is preferably 60°-160°.

Embodiment 2

[0033] The structure of this embodiment is basically the same as that of Embodiment 1, except that the elastic device in this embodiment is made of fiber, and the tensile strength of the fiber is greater than 500 MPa.

[0034] The elastic coupling of the present invention makes full use of the flexibility and rigidity of twisted steel wire ropes, has a simple structure, low cost, and is easy to manufacture. The all-metal structure can be used in various complex working conditions, easy to maintain, stable in performance, large in transmission torque, and capable of absorbing tests The impact of the motor, the shock absorption effect is good.

Abstract

The invention provides an elastic coupling. The coupling comprises a first half coupling, a second half coupling and an elastic component. The elastic component is stranded steel wire ropes which are distributed in a circumferential direction; and two ends of each stranded steel wire rope are fixedly connected with the first half coupling and the second half coupling respectively. The stranded steel wire ropes are arranged between two half couplings to ensure that the coupling can transfer large torsion and has a good vibration reduction effect.

Description

technical field [0001] The invention relates to a shaft coupling, in particular to an elastic shaft coupling. Background technique [0002] At present, in the factory test and type test of large and medium-sized motors such as wind power generators and coal roadheaders, especially in the limit test of wind power generators, due to the structure of the wind power generator itself, it has a large impact during operation. It has a greater impact on drive chain components such as drive motors and couplings. The existing couplings are generally metal diaphragm couplings and universal joint couplings. The existing couplings have the following defects: 1) The coupling structure is complex, expensive, and easily damaged; 2) The coupling It cannot effectively absorb shocks, and the cushioning effect is poor. Contents of the invention [0003] The present invention proposes an elastic coupling, which can not only transmit relatively large torque, but also effectively absorb shocks...
