Small elastic coupling

Abstract

The invention relates to a small elastic coupling. The small elastic coupling comprises a left weight reducing flange, a right weight reducing flange, polyurethane sheath tubes and positioning bolts.The front end surface of the left weight reducing flange abuts against the front end surface of the right weight reducing flange. A plurality of positioning screw holes and at least four weight reducing grooves are uniformly distributed in the left weight reducing flange and the right weight reducing flange. The positioning bolts are connected with the left weight reducing flange and the right weight reducing flange through positioning screw holes and coaxial with the positioning screw holes. The left weight reducing flange is connected with the right weight reducing flange through the positioning bolts. Each polyurethane sheath tube is embedded in the corresponding positioning screw hole of the left weight reducing flange, is coaxial with the corresponding positioning screw hole and wrapsthe corresponding positioning bolt. By the adoption of the small elastic coupling, on the one hand, the structure of the device is greatly simplified, the complexity, weight and size of the device are reduced, and on the other hand, the axial movement and radial jump action force generated during the power transmission process can be effectively reduced while the good power transmission capability and good power transmission accuracy are achieved.

[0002] Couplings are currently important equipment for connecting two adjacent shaft workpieces and realizing power transmission operations. They are used in a huge amount, but in actual use, it is found that the current coupling equipment often has a large structural volume to varying degrees. , As a result, the current coupling cannot effectively meet the needs of use in a narrow environment. On the other hand, it also leads to a relatively large structural volume of the current mechanical equipment, which severely limits and affects the flexibility and flexibility of the coupling equipment. Versatility also leads to the simplification of mechanical equipment and greatly affects the miniaturization design, which is not conducive to the progress and development of mechanical equipment technology. Although there are some coupling equipment that can be used in small spaces, these coupling equipment Often, the structural strength is relatively small, and the stability of power transmission is relatively poor. It is easy to cause large friction loss during operation, and to generate axial movement and radial deflection, and the operation stability is insufficient.
