Technical Field

[0001] This utility model relates to couplings, specifically a coupling clamping structure. Background Technology

[0002] Current couplings are clamped by bolts. Over time, the bolts can damage the bolt holes of the coupling during use and disassembly, resulting in reduced connection tightness and even causing the coupling to lose its balance. Utility Model Content

[0005] The half-coupling also has a groove on the outside of the through hole, the depth of which is greater than the depth of the through hole.

[0006] The inner diameter of the outer ring plate is the same as the inner diameter of the insert sleeve, the outer diameter of the outer ring plate is larger than the outer diameter of the insert sleeve, and the outer diameter of the outer ring plate is larger than the inner diameter of the through hole.

[0007] The outer diameter of the gasket is larger than the inner diameter of the insert sleeve.

[0008] In summary, this utility model achieves the following technical effects:

[0011] This utility model features a hollow groove to facilitate bolt installation and use;

[0012] This utility model is provided with two sets of through holes, one set on the outside and one set on the inside, which together clamp the parts together, resulting in good stability. Attached Figure Description

[0019] Furthermore, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of the technical features being referred to. Thus, a feature specified as "first" or "second" may explicitly or implicitly include one or more of such features. In the description of this utility model, "plurality" means two or more, unless otherwise specifically defined.

[0020] In this utility model, unless otherwise explicitly specified and limited, the terms "installation," "connection," "joining," and "fixing," etc., should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral part; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; they can refer to the internal communication of two components or the interaction between two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model according to the specific circumstances.

[0021] In the present invention, unless otherwise expressly specified or limited, when a first feature is "above" or "below" a second feature, it may mean that the first and second features are in direct contact, or the first and second features are in indirect contact through an intermediary. Furthermore, when a first feature is "above," "above," or "above" a second feature, it may mean that the first feature is directly above or diagonally above the second feature, or simply means that the first feature is at a higher level than the second feature. When a first feature is "below," "below," or "below" a second feature, it may mean that the first feature is directly below or diagonally below the second feature, or simply means that the first feature is at a lower level than the second feature.

[0022] Example:

[0023] Figure 1 This is a coupling clamping structure, comprising two interconnected half-couplings 1. The outer wall of each half-coupling 1 has a slit 11 along the axial direction. Two sets of through holes 13 are provided on both sides of the slit 11. One set of through holes is located on the outer side and the other on the inner side, which clamp together and provide good stability. The half-coupling 1 also has a groove 12 starting from the outer side of the through hole 13. The depth of the groove 12 is greater than the depth of the through hole 13. The space of the groove 12 is larger than that of the through hole, which facilitates the installation of bolts.

[0024] Figure 2 yes Figure 1 A-A direction cross-sectional diagram Figure 3 yes Figure 2 A magnified view of a portion of the image.

[0025] The through holes 13 of the same group are located on both sides of the gap 11 and are aligned for use with bolts for fastening.

[0026] The through holes 13 in the same group are fitted with liners, gaskets, bolts 23, and nuts 26. Figure 3 In the middle, the through hole 13 on the right side is provided with a first inner liner 21 and a first gasket 22, and the through hole 13 on the left side is provided with a second inner liner 24 and a second gasket 25. The first inner liner 21 and the second inner liner 24 have the same structure, as follows:

[0027] The inner lining includes an insert sleeve and an outer ring plate. The insert sleeve extends into the through hole 13, and the outer ring plate is fixed to one end of the insert sleeve and is in close contact with the outer wall of the through hole 13.

[0028] The insert sleeve protects the through hole 13 from bolt damage, thereby extending the service life of the coupling. The outer ring plate prevents the insert sleeve from being squeezed into the through hole.

[0029] The length of the insert sleeve is less than the length of the through hole 13 to prevent the two insert sleeves from colliding with each other during tightening and affecting the locking strength.

[0030] The gasket is tightly attached to the outer ring plate, and one end of the bolt 23 passes through the two embedded sleeves and is tightened by the nut 26. The first gasket 22 and the second gasket 25 are used as gaskets to enhance the tightening strength.

[0031] Since the depth L2 of the slot 12 is greater than the depth L1 of the through hole 13, a step is formed, which facilitates the use of the outer ring plate, gasket, and bolts and nuts.

[0032] The inner diameter of the outer ring plate is the same as the inner diameter of the insert sleeve, the outer diameter of the outer ring plate is larger than the outer diameter of the insert sleeve, the outer diameter of the outer ring plate is larger than the inner diameter of the through hole 13, and the outer diameter of the gasket is larger than the inner diameter of the insert sleeve. This prevents these components from being squeezed into the through hole 13.

[0033] Working principle:

[0034] Install the liner in the through hole beforehand, put the coupling on the main shaft, install the bolts and washers, and then install them in the through hole 13 and lock them with the nut 26.

[0035] A coupling is equipped with four sets of through holes, providing a good clamping effect.

[0036] The above description is merely a preferred embodiment of the present utility model and is not intended to limit the present utility model in any way. Any simple modifications, equivalent changes and alterations made to the above embodiments based on the technical essence of the present utility model shall fall within the scope of the technical solution of the present utility model.
