Description

Technical Field

[0001] The utility model relates to the technical field of mechanical transmission equipment, and particularly relates to a vertical metal laminated flexible coupling. Background Art

[0002] A flexible coupling is a mechanical component used to connect two shafts and transmit rotational motion. Its main feature is the ability to compensate for relative displacements (such as radial, angular, or axial offsets) between the two shafts, while reducing vibration and shock. Flexible couplings are widely used in various mechanical equipment, especially in those applications that require high-precision positioning or where inevitable shaft misalignment exists.

This can easily lead to problems such as excessive vibration of the unit, failure of bearings and the flexible element of the coupling, reducing the stability and reliability of the unit.

[0050] It can be understood that the present utility model also provides a transmission device, which includes the vertical metal lamination flexible coupling as described above.

[0051] Next, the working principle of the vertical metal lamination flexible coupling involved in the embodiment of the present utility model will be described. The working process of this vertical metal lamination flexible coupling consists of two parts: one is the normal torque transmission, i.e., the flexible compensation part; the other is the gravity load distribution part of the upper half coupling and the flexible floating section.

[0052] Normal torque transmission, i.e., the flexible compensation part:

[0053] During operation, torque is transmitted from the upper drive shaft end a to the first mounting disc 1 connected to the drive shaft end a; it is transmitted to the first adapter disc 3-1-1 through the first torque transmission bolt assembly 2; it is transmitted to the first flexible diaphragm assembly 3-1-2 through the third torque transmission bolt assembly 3-1-3. Since the first flexible diaphragm assembly 3-1-2 and the upper spacer shaft 3-1-4 are connected by the adjacent third torque transmission bolt assembly 3-1-3, the torque is transmitted to the upper spacer shaft 3-1-4 through the first flexible diaphragm assembly 3-1-2; it is transmitted to the intermediate shaft 3-2 through the fifth torque transmission bolt assembly 3-4; it is transmitted to the lower spacer shaft 3-3-4 through the sixth torque transmission bolt assembly 3-5; it is transmitted to the second flexible diaphragm assembly 3-3-2 through the fourth torque transmission bolt assembly 3-3-3; the torque is transmitted to the second adapter disc 3-3-1 through the adjacent fourth torque transmission bolt assembly 3-3-3; it is transmitted to the second mounting disc 5 below through the second torque transmission bolt assembly 4, and finally transmitted to the driven shaft end b. Among them, the radial, angular, and axial misalignments between the driven shafts are compensated and absorbed through the deformation of the flexible diaphragms of the first flexible diaphragm assembly 3-1-2 and the second flexible diaphragm assembly 3-3-2.

[0054] Gravity load distribution part of the upper half coupling and the flexible floating section:

[0055] During operation, the gravity loads of components such as the first flexible diaphragm assembly 3-1-2, the third torque transmission bolt assembly 3-1-3, the upper spacer shaft 3-1-4, the flexible section support plate 3-1-6, the intermediate shaft 3-2, the second flexible diaphragm assembly 3-3-2, the fourth torque transmission bolt assembly 3-3-3, the lower spacer shaft 3-3-4, the fifth torque transmission bolt assembly 3-4, and the sixth torque transmission bolt assembly 3-5 are suspended on the first adapter disc 3-1-1 through the axial load-bearing flexible rod 3-1-5 assembly; then the gravity load on the first adapter disc 3-1-1 is suspended on the mounting disc 1 through the first torque transmission bolt assembly 2; finally, the gravity load on the mounting disc 1 is suspended on the upper drive shaft end a through the load-bearing disc 7 and the pre-tightening bolts 8, thus avoiding the influence of axial additional loads on the first flexible diaphragm assembly 3-1-2 and the second flexible diaphragm assembly 3-3-2 due to the gravity loads of related components, and effectively improving the stability and reliability of the vertical metal diaphragm flexible coupling.

[0056] In summary, in order to overcome the deficiencies in the prior art, the present utility model provides a vertical metal diaphragm flexible coupling with a reasonable mechanical model, simple structure, and high reliability. The coupling is provided with an axial load-bearing flexible rod, which can avoid the influence of axial gravity loads on the flexible parts while taking into account the flexible compensation ability, thereby providing a vertical metal diaphragm flexible coupling with a vertical layout, maintenance-free, large compensation ability, good dynamic balance retention, and modular installation.
