Description

Technical Field

[0001] The utility model relates to the technical field of jet grouting pile forming detection, in particular to a metal bellows coupling. Background Art

[0002] Couplings are mainly used for connection in mechanical transmission and are the main components in mechanical transmission. Their function is to connect the driving shaft and the driven shaft to transmit motion and torque, and to compensate for axial, radial and angular deviations caused by manufacturing errors, installation errors, deformation after load and temperature changes. Bellows couplings are a type of coupling that transmits motion by directly welding or bonding a thin-walled tube with a corrugated shape to the two halves of the coupling.

[0003] The existing Chinese patent with the authorization announcement number CN211874971U discloses a welded metal bellows coupling, wherein a group of transmission units are respectively arranged at both ends of the welded metal bellows on the shaft sleeve, and the transmission units include an expansion ring, a transmission ring A and a transmission ring B, wherein the transmission ring A and the transmission ring B are parallel transmission rings. The utility model installs a group of transmission units at both ends of the welded metal bellows, which is a special component of the welded metal bellows, and the transmission units at both ends can balance the welded metal bellows at the same time. By adjusting the tightening force of the adjusting bolt on the transmission ring A and the transmission ring B, the thrust formed by the chamfer of the transmission ring A and the transmission ring B on the wedge surface of the expansion ring is adjusted, thereby changing the contraction and relaxation of the expansion ring opening, which is achieved by the friction force generated after clamping. When an abnormal overload occurs and the friction force is insufficient to transmit torque, the shaft sleeves at both ends of the welded metal bellows will slip and automatically detach from the transmission shaft, thereby ensuring the safety of the overall equipment.

[0004] The disadvantages of the above-mentioned prior art solutions are that the installation process between the coupling and the transmission shaft is relatively complicated and there is still room for improvement in terms of ease of use. Utility Model Content

Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0026] like Figure 1-Figure 5 As shown, a metal bellows coupling comprises a metal bellows body 1, a connecting mechanism 2 and a sleeve mechanism 3.

The connecting mechanism 2 comprises a mounting plate 21, on the side wall of which a connecting plate 22 is symmetrically distributed and fixedly connected. The sleeve mechanism 3 comprises a mounting plate 21, on the side wall of which a connecting plate 22 is symmetrically distributed and fixedly connected. One end face of the mounting plate 21 is fixedly mounted on the connecting plate 22 on the mounting plate 21 through the connecting plate 22. A glue groove 35 is provided on the other end face of the mounting plate 21. A connecting ring 34 is coaxially arranged and fixedly connected at the notch of the glue groove 35. A sleeve ring 38 is coaxially arranged and fixedly connected on the connecting ring 34. A diaphragm 37 is provided between the connecting ring 34 and the sleeve ring 38.

[0027] In some specific embodiments, shaft sleeve mechanisms 3 are provided on the connection mechanisms 2 on both sides of the metal bellows body 1 .

[0028] An annular groove 36 is provided on the end face of the connecting ring 34 which is away from the mounting plate 31, the circumference of the diaphragm 37 is bonded to the annular groove 36, glue is provided in the glue groove 35, and through grooves 39 are evenly distributed in an annular shape and penetrate through the side wall of the sleeve ring 38. During the production and assembly process of the shaft sleeve mechanism 3, the connecting ring 34 is first fixedly installed at the notch of the glue groove 35, glue is injected into the glue groove 35, the glue groove 35 is sealed through the diaphragm 37, and finally the sleeve ring 38 is fixedly installed on the connecting ring 34.

[0030] In order to facilitate the understanding of the embodiments of this solution by those skilled in the art, the working principle of this solution is briefly described in combination with specific application scenarios:

[0031] When in use, one of the sleeve mechanisms 3 on both sides of the metal bellows body 1 is connected to the drive shaft, and the other is connected to the transmission shaft.
