Description

Technical Field

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

[0002] A coupling is a mechanical part used to connect two shafts in different mechanisms so that they rotate together to transmit torque. In high-speed and heavy-load power transmission, some couplings also have the functions of buffering, vibration reduction and improving the dynamic performance of the shaft system. The coupling consists of two halves, which are connected to the driving shaft and the driven shaft respectively. Generally, most power machines are connected to the working machine with the help of couplings.

[0003] Existing multi-purpose couplings usually require hammering, cutting or heating when disassembling, which is not only time-consuming but may also damage the coupling or shaft. Due to the difficulty in disassembly, the cost of maintenance or replacement of parts is high and requires more labor.

[0004] Therefore, those skilled in the art provide a multi-purpose coupling to solve the problems raised in the above background technology. Utility Model Content

[0005] The purpose of the utility model is to solve the shortcomings existing in the prior art, and a multi-purpose coupling is proposed. The user passes the threaded rod through the fixing plate and makes it fit tightly on the fixing plate through the threaded sleeve. Then, the end of the threaded rod is inserted into the groove and connected with the thread of the threaded rod by rotating the nut, so that the right half-shaft coupling and the left half-shaft coupling are firmly fixed together, ensuring that the coupling remains stable during operation and will not loosen. At the same time, the function of the fixing plate is to prevent the coupling from shifting during rotation. When disassembly is required, the nut only needs to be rotated and easily removed to quickly separate the two half-shaft couplings, realizing a quick and easy disassembly process.

[0006] In order to achieve the above purpose, the utility model provides the following technical solutions:

[0007] A multi-purpose coupling, comprising a right half-shaft coupling, a left half-shaft coupling and a cooling mechanism, wherein the right half-shaft coupling and the left half-shaft coupling are both provided with a fixing mechanism, wherein the fixing mechanism comprises a plurality of threaded rods, the outer walls of the plurality of threaded rods are sleeved with threaded sleeves, a fixing plate is provided on one side of the right half-shaft coupling and the left half-shaft coupling near the center of the threaded rod, the other side of the threaded rod at the upper and lower ends are both threadedly connected with nuts, the one side of the threaded rod at the front and rear ends are both threadedly connected with nuts, the front and rear ends of the outer wall of the right half-shaft coupling are both provided with grooves, and the upper and lower ends of the outer wall of the left half-shaft coupling are both provided with grooves;

[0008] Through the above technical solution, the user passes the threaded rod through the fixing plate and makes it fit tightly on the fixing plate through the threaded sleeve. Then, the end of the threaded rod is inserted into the groove and connected with the thread of the threaded rod by rotating the nut. In this way, the right half-shaft coupling and the left half-shaft coupling are firmly fixed together, ensuring that the coupling remains stable during operation and will not loosen. At the same time, the function of the fixing plate is to prevent the coupling from shifting during rotation. When disassembly is required, only the nut needs to be rotated and easily removed to quickly separate the two half-shaft couplings, realizing a quick and easy disassembly process.

[0009] Furthermore, the cooling mechanism comprises a cooling liquid pipe, a cooling liquid groove is provided at the upper end of the outer wall of the cooling liquid pipe, and a convex block is provided at the upper end of the cooling liquid pipe;

[0010] Through the above technical solution, the user first removes the bump, then pours the coolant into the coolant pipe, and then replaces the bump in the coolant tank. The design is intended to effectively seal the slot to prevent the coolant from leaking when the coupling rotates. This operation method not only makes it easy for the user to add or replace the coolant, but also effectively prevents the coupling from affecting its operating performance due to increased temperature during operation.

[0011] Furthermore, the inner wall of the fixing plate is evenly threadedly connected to the threaded rod;

[0012] Through the above technical solution, it is ensured that the connection between the fixing plate and the threaded rod will not loosen due to vibration or external force, thereby improving the stability and reliability of the entire coupling system.

[0013] Furthermore, the lower ends of the plurality of nuts are fitted with the grooves;

[0014] Through the above technical solution, the stability of the connection is improved and the looseness caused by vibration is reduced.

[0015] Furthermore, the plurality of threaded sleeves are tightly fitted to the fixing plate;

[0016] The above technical solution allows the position of the fixing plate to be fine-tuned so as to achieve precise alignment during installation or maintenance.

[0017] Furthermore, the protrusion is tightly fitted with the cooling liquid tank;

[0018] Through the above technical solution, the tight fit can form a better sealing effect, prevent coolant leakage, and ensure the normal operation of the cooling system.

[0019] Further, a plurality of the threaded rods penetrate the right half-shaft coupling and the left half-shaft coupling to the inner wall of the groove;

[0020] Through the above technical solution, multiple threaded rods can ensure the alignment accuracy between the left and right half-shaft couplings and prevent vibration and wear caused by asymmetry.

[0021] The utility model has the following beneficial effects:

[0022] 1. The utility model proposes a multi-purpose coupling. The user passes the threaded rod through the fixing plate and makes it fit tightly on the fixing plate through the threaded sleeve. Then, the end of the threaded rod is inserted into the groove and connected with the thread of the threaded rod by rotating the nut. In this way, the right half-shaft coupling and the left half-shaft coupling are firmly fixed together, ensuring that the coupling remains stable during operation and will not loosen. At the same time, the function of the fixing plate is to prevent the coupling from shifting during rotation. When disassembly is required, only the nut needs to be rotated and easily removed to quickly separate the two half-shaft couplings, realizing a quick and easy disassembly process.

[0032] The following will be combined with the drawings in the specific implementation of the utility model to clearly and completely describe the technical solutions in the specific implementation of the utility model. Obviously, the specific implementation described is only a part of the specific implementation of the utility model, not all of the specific implementation. Based on the specific implementation of the utility model, all other specific implementations obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0034] The user passes the threaded rod 302 through the fixing plate 304 and makes it fit tightly on the fixing plate 304 through the threaded sleeve 305. Then, the end of the threaded rod 302 is inserted into the groove 301 and connected with the thread of the threaded rod 302 by rotating the nut 303. In this way, the right half-shaft coupling 1 and the left half-shaft coupling 2 are firmly fixed together, ensuring that the coupling remains stable during operation and will not loosen. At the same time, the function of the fixing plate 304 is to prevent the coupling from shifting during rotation. When disassembly is required, only the nut 303 needs to be rotated and easily removed to quickly separate the two half-shaft couplings, realizing a quick and easy disassembly process.

[0035] Reference Figure 3 and Figure 4The cooling mechanism 4 includes a coolant pipe 401, a coolant tank 402 is provided at the upper end of the outer wall of the coolant pipe 401, and a protrusion 403 is provided at the upper end of the coolant pipe 401. The user first removes the protrusion 403, and then pours the coolant into the coolant pipe 401. Next, the protrusion 403 is replaced in the coolant tank 402. The design is to effectively seal the notch to prevent the coolant from leaking when the coupling rotates. This operation method is not only convenient for the user to easily add or replace the coolant, but also effectively prevents the coupling from affecting the operating performance due to the increase in temperature during operation. The inner wall of the fixed plate 304 is evenly threaded with the threaded rod 302 to ensure that the connection between the fixed plate 304 and the threaded rod 302 will not loosen due to vibration or external force. Thereby improving the stability and reliability of the whole coupling system, the lower ends of the multiple nuts 303 are fitted with the groove 301, improving the stability of the connection and reducing the looseness caused by vibration, the multiple threaded sleeves 305 are tightly fitted with the fixing plate 304, allowing the position of the fixing plate 304 to be fine-tuned to facilitate precise alignment during installation or maintenance, the bump 403 is tightly fitted with the coolant groove 402, and the tight fit can form a better sealing effect to prevent coolant leakage and ensure the normal operation of the cooling system, the multiple threaded rods 302 penetrate the right half-shaft coupling 1 and the left half-shaft coupling 2 to the inner wall of the groove 301, the multiple threaded rods 302 can ensure the alignment accuracy between the left and right half-shaft couplings 1, and prevent vibration and wear caused by asymmetry.

[0036] Working principle: The user passes the threaded rod 302 through the fixing plate 304 and makes it fit tightly on the fixing plate 304 through the threaded sleeve 305. This step ensures a stable connection between the threaded rod 302 and the fixing plate 304. The design of the fixing plate 304 also prevents the coupling from shifting during rotation. Subsequently, the end of the threaded rod 302 is inserted into the groove 301, which is located at the interface between the right half-shaft coupling 1 and the left half-shaft coupling 2. The nut 303 is connected to the thread of the threaded rod 302 by rotating it. The rotation of the nut 303 fixes the threaded rod 302 in the groove 301, thereby firmly fixing the two half-shaft couplings together. This connection method ensures that the coupling remains stable during operation and will not loosen. When disassembly is required, the nut 303 only needs to be rotated and easily removed to quickly separate the two half-shaft couplings, achieving a quick and easy disassembly process. The user then removes the bump 403 and pours the coolant into the coolant pipe 401. The coolant pipe 401 is connected to the coolant tank 402 for storing the coolant. Then, the bump 403 is replaced in the coolant tank 402. The design is intended to effectively seal the notch to prevent the coolant from leaking when the coupling rotates. This operation method not only makes it easy for the user to add or replace the coolant, but also effectively prevents the coupling from affecting its operating performance due to increased temperature during operation.

[0037] Finally, it should be noted that the above is only a preferred specific implementation method of the present invention and is not intended to limit the present invention. Although the present invention has been described in detail with reference to the aforementioned specific implementation methods, those skilled in the art can still modify the technical solutions recorded in the aforementioned specific implementation methods, or make equivalent substitutions for some of the technical features therein.
