Abstract
Description
Technical Field
[0001] This utility model relates to the field of coupling transmission technology, and more specifically, to a connecting component assembly for a universal coupling. Background Technology
[0002] Universal couplings are commonly used mechanical transmission components used to transmit power between different axes, and are widely used in automobiles, construction machinery, machine tools, and other fields. During the use of universal couplings, the connecting components play a crucial role in the connection; their stability and reliability directly affect the overall transmission performance and service life of the universal coupling. Currently, common universal coupling connector assemblies on the market have some shortcomings in their structural design. The connections between the housings of some components are not secure enough, making them prone to loosening during long-term use and affecting transmission accuracy. At the same time, some connectors lack effective protective structures at the bolt joints, making them susceptible to wear after prolonged use and reducing the component's lifespan. Furthermore, the bolt and nut connection methods of some components are inconvenient to install and disassemble, increasing maintenance costs and time.
[0003] Therefore, a universal coupling assembly with a reasonable structure, strong connection, long service life, and easy installation and disassembly is needed to solve the above problems. Utility Model Content
[0004] In view of the shortcomings of the prior art, the purpose of this utility model is to provide a connecting component assembly for universal couplings to solve the above problems.
[0005] A connecting component assembly for a universal coupling includes a connecting component, a middle shell, an upper shell, a lower shell, bolts, and nuts, wherein the upper shell, middle shell, and lower shell are connected to each other by the connecting component, bolts, and nuts.
[0006] Preferably, both ends of the connector are provided with connecting holes for bolts to pass through.
[0007] Preferably, the connector is provided with an arc, the curvature of which corresponds to the circumferential arc of the upper shell.
[0008] Preferably, the middle shell, upper shell, and lower shell are each provided with six or eight bolt holes.
[0009] Preferably, the bolt is an internal hex bolt.
[0010] Preferably, a washer is also provided between the nut and the bolt connection.
[0011] Preferably, the end face of the connector that contacts the bolt head is provided with anti-slip texture.
[0012] Compared with existing technologies, it has the following advantages: 1. This connector assembly for universal couplings connects the upper, middle, and lower housings through the cooperation of connectors, bolts, and nuts. The connectors have connecting holes at both ends for bolts to pass through, ensuring the firmness of the connection between the housings and effectively preventing loosening during long-term use, thus improving the transmission accuracy of the universal coupling. 2. The connector adopts an arc design, the curvature of which corresponds to the circumference of the upper shell. This increases the contact area between the connector and the upper shell, disperses the force, reduces local stress concentration, and extends the service life of the connector and the upper shell. 3. The middle shell, upper shell, and lower shell are equipped with six or eight bolt holes, and the number of bolts can be selected according to the actual torque requirements, which enhances the versatility and flexibility of the components. 4. The bolts are internal hex bolts, which facilitate installation and disassembly in confined spaces and improve maintenance convenience. Washers are placed at the connection between the nut and the bolt to prevent pressure damage, seal and prevent loosening, further improving the reliability of the connection. Anti-slip grooves are set on the contact surface between the connector and the bolt head to increase the friction between the two, prevent the bolt from loosening, reduce wear and extend the overall service life of the component.

[0019] The embodiments of the present invention will now be described with reference to the accompanying drawings.
[0020] like Figure 1 and combined Figures 2 to 5 As shown, a connecting component assembly for a universal coupling includes a connecting component 1, a middle shell 2, an upper shell 3, a lower shell 4, a bolt 5, and a nut 6. The upper shell 3, the middle shell 2, and the lower shell 4 are connected by the connecting component 1, the bolt 5, and the nut 6. Both ends of the connecting component 1 are provided with connecting holes 7 for the bolt 5 to pass through. The connecting component 1 is arc-shaped, and its arc corresponds to the circumferential arc of the upper shell 3.
[0021] Furthermore, the middle shell 2, upper shell 3, and lower shell 4 are each provided with six or eight bolt holes 8, and the bolts 5 are internal hex bolts.
[0022] Furthermore, a washer is provided between the nut 6 and the bolt 5, and anti-slip texture 9 is provided on the end face of the connector 1 that contacts the bolt head of the bolt 5.
[0023] Compared with the existing technology, it has the following advantages: The connecting component assembly for the universal coupling connects the upper shell 3, the middle shell 2 and the lower shell 4 through the cooperation of the connecting component 1, the bolt 5 and the nut 6. The connecting component 1 has connecting holes 7 at both ends for the bolt 5 to pass through, which ensures the firmness of the connection between the shells, effectively avoids loosening during long-term use and improves the transmission accuracy of the universal coupling.
[0024] The connector 1 is designed with an arc, the curvature of which corresponds to the circumference of the upper shell 3. This increases the contact area between the connector 1 and the upper shell 3, disperses the force, reduces local stress concentration, and extends the service life of the connector 1 and the upper shell 3. The middle shell 2, upper shell 3, and lower shell 4 are provided with six or eight bolt holes 8, allowing the number of bolts 5 to be selected according to actual torque requirements, thus enhancing the versatility and flexibility of the assembly.
[0025] Bolt 5 is an internal hex bolt, which is convenient for installation and disassembly in confined spaces and improves maintenance convenience. A washer is provided at the connection between nut 6 and bolt 5, which plays a role in preventing pressure damage, sealing and preventing loosening, further improving the reliability of the connection. Anti-slip texture 9 is provided on the contact end face of connector 1 and bolt 5, which increases the friction between the two, prevents bolt 5 from loosening, reduces wear, and extends the overall service life of the component.
[0026] During installation of the universal coupling's connecting component assembly, first align the upper shell 3, middle shell 2, and lower shell 4 according to the preset positions, ensuring that the bolt holes 8 of each correspond one-to-one. Then, place the connecting component 1 on the outside of the upper shell 3, aligning the connecting holes 7 at both ends of the connecting component 1 with the bolt holes 8 of the upper shell 3, middle shell 2, and lower shell 4. Next, pass the hex bolts 5 sequentially through the connecting holes 7 of the connecting component 1 and the bolt holes 8 of the upper shell 3, middle shell 2, and lower shell 4. Place a washer on the other end of the bolt 5, and then tighten the nut 6. Finally, use an Allen wrench to tighten the nut 6, ensuring that the upper shell 3, middle shell 2, lower shell 4, and connecting component 1 are tightly connected together, completing the installation. During use, because the connecting component 1 fits snugly against the upper shell 3 with an arc, the contact area is increased, distributing the force. At the same time, the anti-slip texture 9 increases the friction between the connecting component 1 and the bolt head 5. The washer prevents the nut 6 from damaging the shell and the bolt 5 from loosening, making the entire assembly firmly connected, not easily worn, and effectively ensuring the stable transmission of the universal coupling. When maintenance or disassembly is required, simply use an Allen wrench to unscrew nut 6, remove bolt 5 and washer, and the parts can be separated. The operation is convenient.
[0027] Those skilled in the art will readily understand that the above description is merely a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
