Description

Technical Field

[0001] The utility model relates to the technical field of couplings, in particular to a self-lubricating coupling. Background Art

[0002] A coupling is a device that connects two shafts or a shaft and a rotating part. They rotate together during the process of transmitting motion and power and do not disengage under normal circumstances. It is sometimes also used as a safety device to prevent the connected parts from being subjected to excessive loads and play a role in overload protection. A coupling, also known as a coupling, is a mechanical component used to firmly connect the driving shaft and the driven shaft in different mechanisms so that they rotate together and transmit motion and torque.

[0003] After searching, the announcement number CN215293310U is a self-lubricating coupling, which includes a left coupling, a right coupling, a sealed cover, an oil storage channel and a ball. Through research and analysis, it is found that although the coupling has the advantages of self-lubrication, improved transmission effect, and convenient use, it still has the following disadvantages to a certain extent;

[0004] For example, during the lubrication process of the coupling, the ball is rotated to apply oil to the shaft. The contact area between the ball and the shaft is small, the lubrication effect is poor, and the lubricating oil cannot be efficiently transmitted. In order to solve the above technical problems, it is necessary for us to design a self-lubricating coupling to solve the above problems. Utility Model Content

[0005] The utility model aims to provide a self-lubricating coupling, which has the advantage of good lubrication effect and solves the problem that the contact lubrication area between the ball and the rotating shaft of the coupling is limited.

[0007] Preferably, the support members penetrate into the inner cavities of the left channel and the right channel of the rotating shaft respectively, and a sealing gasket is provided on one side of the connection between the upper coupling and the lower coupling respectively.

[0008] Preferably, bolts are provided through the surface of the lower coupling, and the bolts sequentially penetrate the upper coupling and the lower coupling and are threadedly sleeved with nuts.

[0009] Preferably, the bolts are movably connected to the inner walls of the upper coupling and the lower coupling respectively, and the nut is in close contact with the surface of the upper coupling.

[0010] Preferably, connecting pieces are fixedly mounted on the surfaces of the left channel and the right channel of the rotating shaft, respectively, and the surfaces of the upper coupling and the lower coupling are respectively snapped onto the surfaces of the connecting pieces.

[0011] Preferably, the oil storage channel and one end of the oil outlet are connected to each other, and the oil outlets are arranged at equal distances.

[0012] Compared with the prior art, the beneficial effects of the utility model are as follows:

[0013] 1. The utility model adopts the cooperation of the oil storage channel, the sealing cover plate, the oil outlet, the sponge, the movable ring and the sealing gasket, and with the help of the arrangement of the upper coupling and the lower coupling at the surface, the lubricating oil is introduced into the oil storage channel and transferred to the oil outlet to be sucked away by the sponge, and the sponge transfers the lubricating oil to the components by contact, thereby achieving a comprehensive lubrication effect.

[0014] 2. The utility model cooperates with support members, bolts, nuts and connecting members. The support members are installed on the sides of the left channel and the right channel of the rotating shaft, so that they are assembled and connected with each other, thereby extending the service life of the main body. The fixed setting of the bolts and nuts can adjust the upper coupling and the lower coupling to rotate around their own axes. BRIEF DESCRIPTION OF THE DRAWINGS

[0019] See also Figure 1-Figure 3A self-lubricating coupling comprises a left shaft channel 1 and a right shaft channel 2, a support member 3 is respectively arranged between the left shaft channel 1 and the right shaft channel 2, a lubrication mechanism 4 is respectively arranged on the surface of the left shaft channel 1 and the right shaft channel 2, the lubrication mechanism 4 comprises an upper coupling 5 and a lower coupling 6, an oil storage channel 7 is respectively arranged on the surface of the upper coupling 5 and the lower coupling 6, a sealing cover plate 8 is arranged on the surface of the lower coupling 6, an oil outlet 9 and a sponge 10 are respectively arranged on the inner walls of the left shaft channel 1 and the right shaft channel 2, and a movable ring 11 is respectively inlaid and installed on the inner walls of the left shaft channel 1 and the right shaft channel 2.

[0020] See also Figure 2 The support member 3 penetrates through the inner cavity of the left channel 1 and the right channel 2 of the rotating shaft respectively. A sealing gasket 12 is provided on one side of the connection between the upper coupling 5 and the lower coupling 6. By providing the sealing gasket 12, the sealing between the two couplings can be ensured. The structure is simple and easy to use.

[0021] See also Figure 1 and Figure 2 A bolt 13 is provided through the surface of the lower coupling 6. The bolt 13 passes through the upper coupling 5 and the lower coupling 6 in sequence and is threadedly sleeved with a nut 14. By providing the nut 14, the position of the bolt 13 can be locked and the assembly installation location can be fixed.

[0022] See also Figure 1 and Figure 2 The bolts 13 are movably connected to the inner walls of the upper coupling 5 and the lower coupling 6 respectively. By setting the bolts 13, the components are positioned to facilitate their installation. The nut 14 is in close contact with the surface of the upper coupling 5.

[0023] See also Figure 2 and Figure 3 The surfaces of the left channel 1 and the right channel 2 of the rotating shaft are respectively fixedly installed with connecting pieces 15. By setting the connecting pieces 15, the wear caused by friction is reduced and the transmission effect is improved. The surfaces of the upper coupling 5 and the lower coupling 6 are respectively snapped into the surfaces of the connecting pieces 15.

[0024] See also Figure 3 The oil storage channel 7 and one end of the oil outlet 9 are interconnected, and the oil outlets 9 are arranged at equal distances. By setting the oil outlets 9, it is convenient to transfer the lubricating liquid by conduction, thereby increasing the hygroscopicity of the sponge 10.

[0025] When in use, the support member 3 is inserted into the left channel 1 of the rotating shaft and the right channel 2 of the rotating shaft, and the upper coupling 5 and the lower coupling 6 are clamped to the surface of the connecting member 15, so that the sealing gaskets 12 arranged on the contact surfaces fit each other to ensure the sealing between them, and the connection is enhanced by fixing through threaded transmission of multiple bolts 13 and nuts 14. The rotating shaft is inserted to match the movable ring 11, and the sealing cover plate 8 is opened to add lubricating oil to the oil storage channel 7. When the upper coupling 5 and the lower coupling 6 are used in conjunction with the rotating shaft, the rotating shaft contacts the sponge 10 in the left channel 1 of the rotating shaft and the right channel 2 of the rotating shaft, the sponge 10 is turned over, and the lubricating oil inside the oil storage channel 7 will seep out from multiple oil outlets 9, thereby achieving a self-lubricating effect.

[0026] In summary: the self-lubricating coupling solves the problem of limited contact lubrication area between the ball and the rotating shaft of the coupling through the cooperation of the left rotating shaft channel 1, the right rotating shaft channel 2, the support 3, the upper coupling 5, the lower coupling 6, the oil storage channel 7, the sealing cover plate 8, the oil outlet 9, the sponge 10 and the movable ring 11.
