Description

Technical Field

[0001] This utility model relates to the field of coupling technology between shaft systems on the same axis, specifically a device for coupling between shaft systems on the same axis. Background Technology

[0002] In industries such as petrochemicals, cement, and steam turbines, it is common to use a method where two shaft systems on the same axis first start with low-speed linkage, with one shaft system acting as a power source to drive the rotation of the other shaft system.

[0003] In a set of coaxial shaft systems, the driving shaft maintains its own rotational speed, while the driven shaft suddenly or slowly accelerates. If the power source of the driving shaft cannot be damaged, the driven shaft must automatically disengage from the driving shaft. When the speed of the driven shaft is lower than that of the driving shaft, and immediate linkage between the two shafts is required, the device must immediately meet this requirement. Alternatively, if both the driving and driven shafts have stopped and are then restarted, the device must still immediately meet this requirement.

[0004] Currently, when the petrochemical and cement industries encounter such demands, they employ complex equipment that requires manual on-site operation, resulting in poor safety and economic efficiency. Utility Model Content

[0005] To address the shortcomings of existing technologies, this invention provides a device for coupling between shaft systems on the same axis, thus solving the problems mentioned in the background section.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a coupling device between shaft systems on the same axis, comprising an outer locking ring, an outer retaining ring, a cam plate, a spring plate, an inner retaining ring, and an inner top ring. The outer locking ring has an inner hole and locks the outer arc apex of the cam plate through the inner hole. The outer retaining ring has a square hole and evenly positions the inner top ring near the outer arc apex through the square hole. The cam plate rotates at a small angle due to friction, gradually lengthening or shortening the vertical distance of the arc at the outer retaining ring, thereby interlocking or disengaging the outer locking ring and the inner top ring. The shaft systems on the same axis, where the outer locking ring is located and the shaft systems where the inner top ring is located, automatically form a linkage or disengagement between the two shaft systems through the frictional rotation of multiple cam plates. The inner top ring has an inner hole and a keyway. The outer locking ring has several mounting holes on its outer side. The spring plate has several windows.

[0007] Preferably, the spring sheet has an irregularly shaped window inside, and each irregularly shaped window has a protrusion fixedly connected inside. The spring sheet presses against the waist of the cam sheet through the protrusion, so that multiple parts move in a unified manner.

[0008] Preferably, the inner retaining ring has a square hole inside, and the inner retaining ring is used to evenly position the inner top ring near the inner end arc apex through the square hole.

[0009] Preferably, the inner top ring abuts against the inner arc top of the cam plate through its outer circle, and connects to another shaft system through its inner hole and keyway.

[0010] Preferably, the outer locking ring and the inner top ring lock the cam plate to its own rotation degree.

[0011] Preferably, the spring sheet presses against the waist of the inner top ring through the protrusion on the irregular window, so that the outer locking ring and the inner top ring can be interlocked or disengaged.

[0012] This utility model provides a device for coupling between shaft systems on the same axis, which has the following beneficial effects:

[0013] This device for coupling shafts on the same axis has an outer locking ring with a mounting hole to connect to the power source shaft on the same axis, and an inner top ring with an inner hole and keyway to connect to the passive shaft on the same axis. It is easy to install and maintain. One end of the outer locking ring has a mounting hole for installing a protective cover, which can prevent the intrusion of larger particles and allow a small amount of lubricating oil to enter for lubrication. It is simple and convenient. Attached Figure Description

[0028] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0029] Please see Figures 1 to 13 This utility model provides a technical solution: a coupling device between shaft systems on the same axis, including an outer locking ring 1, an outer retaining ring 2, a cam plate 3, a spring plate 4, an inner retaining ring 5, and an inner top ring 6. The outer locking ring 1 locks the outer end arc top of the cam plate 3 through its inner hole. A required shaft system is connected through the mounting hole inside the outer locking ring 1. The outer retaining ring 2 evenly positions the cam plate 3 near the outer end arc top through its square hole. The cam plate 3 generates a small rotation angle through friction, gradually lengthening or shortening the vertical distance of the arc at the outer retaining ring 2, thereby interlocking or disengaging the outer locking ring 1 and the inner top ring 6. The spring plate 4 presses against the waist of the cam plate 3 through the protrusion in its irregular window, causing multiple parts to move in unison. The inner retaining ring 5 evenly positions the cam plate 3 near the inner end arc top through its square hole. The inner top ring 6 presses against the inner arc top of the cam plate 3 through its outer circle. Another shaft system is connected through the inner hole and keyway of the inner top ring 6.

[0030] Spring plate 4 is positioned between outer retaining ring 2 and inner top ring 6, and cam plate 3 is aligned and secured in the middle through the irregularly shaped windows of these three parts. This process continues until all cam plates 3 are installed.

[0031] As a preferred embodiment of this utility model, the outer locking ring 1 is positioned and installed with a sleeve consisting of an outer retaining ring 2, a spring plate 4, an inner retaining ring 5, and a cam plate 3.

[0032] The outer locking ring 1 can also be connected to the upper drive shaft system, i.e., the power source, on the same axis through its own mounting hole.

[0033] The inner top ring 6 rotates around its own axis and generates friction with the inner arc of the cam plate 3, causing the vertical distance of the cam plate 3 to shorten and be in a disengaged state before being inserted into the sleeve composed of the outer retaining ring 2, spring plate 4, inner retaining ring 5, and cam plate 3.

[0034] The inner top ring 6 can be connected to another shaft system, namely the passive shaft system, on the same axis through its own inner hole and keyway.

[0035] In summary, this device for coupling shaft systems on the same axis connects the shaft system on the power source through the six mounting holes on the outer locking ring 1, and connects the passive shaft system to the production facility through the inner hole and keyway on the inner retaining ring 5. The small friction force absorbed by the cam plate 3 and the small angle of rotation achieve the interlocking transmission and disengagement failure on the same axis. On the same axis, the shaft system where the outer locking ring 1 is located and the shaft system where the inner top ring 6 is located automatically form linkage or disengagement between the two shaft systems through the frictional rotation of multiple cam plates 3.

[0036] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
