Description

Technical Field

[0001] This utility model relates to the field of universal coupling technology, and in particular to a universal coupling with self-lubricating function. Background Technology

[0002] In modern industrial production, mechanical transmission systems play a crucial role, and universal couplings, as key components in the field of mechanical transmission, are widely used in various mechanical equipment. They enable torque transmission between two shafts with different axes, while allowing for a certain angle of relative movement between the two shafts. This characteristic makes them indispensable in many complex working conditions.

[0003] Although universal couplings are widely used, traditional lubrication methods bring many inconveniences and hidden dangers to their use. Traditional universal couplings typically rely on periodic manual addition of lubricating oil to maintain good lubrication between components. However, in actual industrial production environments, this lubrication method has significant limitations; periodic manual lubrication requires a large investment of manpower and time. Operators need to strictly adhere to prescribed intervals for equipment shutdown inspections and lubrication operations, which not only affects equipment uptime and reduces production efficiency, but also increases the company's operating costs due to frequent maintenance operations. Therefore, a universal coupling with self-lubricating function has been proposed. Utility Model Content

[0014] (III) Beneficial Effects

[0015] This utility model provides a universal coupling with self-lubricating function, which has the following beneficial effects:

[0016] 1. This universal coupling with self-lubricating function, through the setting of the lubrication mechanism, firstly, the oil temperature is detected by the oil temperature sensor near the main shaft during use. If the oil temperature is too high, the signal is transmitted to the PLC controller on one side. The PLC controller controls the oil pump to start, and delivers the lubricating oil in the oil tank to the cavity inside the auxiliary shaft through the flow pipe. With the help of several oil outlet holes on the inner wall of the cavity, the self-lubricating effect of the main shaft and the auxiliary shaft is achieved. There is no need for the operator to stop the machine for manual lubrication, which reduces the workload of the operator and avoids the impact of downtime on work efficiency.

[0017] 2. This universal coupling with self-lubricating function, through the setting of the connection mechanism, requires the movable flange to be connected to the external fixed flange during use. The movable flange can slide or rotate on the surface of the connecting pipe. Simply insert the external mounting pipe into the connecting pipe, and then rotate the movable flange to align the connection hole on the surface of the movable flange with the connection hole on the surface of the fixed flange. Secure it with a double-ended screw and a positioning nut. Unlike traditional couplings, there is no need for complicated and time-consuming alignment and installation operations, which greatly improves installation efficiency and reduces installation difficulties caused by positional deviations and potential subsequent transmission problems.

All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model without creative effort are within the scope of protection of the present utility model.

[0024] Please see Figures 1 to 4This utility model provides a technical solution: a universal coupling with self-lubricating function, including a main shaft 1, an auxiliary shaft 2 rotatably connected to the surface of the main shaft 1, and a cavity inside the auxiliary shaft 2. A lubrication mechanism 3 is connected through one side of the cavity. The lubrication mechanism 3 achieves self-lubrication of the main shaft 1 and the auxiliary shaft 2, eliminating the need for manual lubrication by operators, reducing the workload of workers, and avoiding downtime that affects work efficiency. Both the main shaft 1 and the auxiliary shaft 2 are equipped with a connecting mechanism 4 at their ends. The connecting mechanism 4 eliminates the need for complex and time-consuming alignment and installation operations as with traditional couplings, greatly improving installation efficiency and reducing installation difficulties caused by positional deviations and potential subsequent transmission problems.

[0025] The lubrication mechanism 3 includes a flow pipe 301 that runs through the cavity. An oil pump 302 is connected to one side of the flow pipe 301. The output end of the oil pump 302 is connected to an oil storage tank 303 through a hose. A PLC controller 304 is electrically connected to one side of the oil pump 302 through a power line. An oil temperature sensor 305 is electrically connected to one side of the PLC controller 304 through a power line.

[0026] The connecting mechanism 4 includes a connecting pipe 401 installed at the ends of the main shaft 1 and the auxiliary shaft 2, and a movable flange 402 is slidably connected to the surface of the connecting pipe 401;

[0027] The oil temperature sensor 305 is installed on the inner wall of the main shaft 1, and the auxiliary shaft 2 has several oil outlet holes inside, which serve to discharge oil.

[0028] An installation pipe 5 is inserted inside the connecting pipe 401. A fixed flange 6 is fixedly connected to one side of the installation pipe 5. The fixed flange 6 serves to connect the movable flange 402.

[0029] The movable flange 402 has a connection hole on its surface, and a double-ended screw 7 is inserted into the connection hole. The double-ended screw 7 serves to fix the flange in place.

[0030] The double-ended screw 7 is inserted into the inside of the fixed flange 6. Both sides of the double-ended screw 7 are threaded with positioning nuts 8. The positioning nuts 8 serve to fix the double-ended screw 7.

[0033] In this invention, the working steps of the device are as follows:

[0034] First step: When in use, the oil temperature sensor 305 near the main spindle 1 first detects the oil temperature. If the oil temperature is too high, it transmits the signal to the PLC controller 304 on one side. The PLC controller 304 controls the oil pump 302 to start, and delivers the lubricating oil inside the oil tank 303 to the cavity inside the auxiliary shaft 2 through the flow pipe 301, which cooperates with several oil outlet holes on the inner wall of the cavity.

[0035] The second step: When using it, the movable flange 402 needs to be connected to the external fixed flange 6. The movable flange 402 can slide or rotate on the surface of the connecting pipe 401. Simply insert the external mounting pipe 5 into the connecting pipe 401, and then rotate the movable flange 402 so that the connecting hole on the surface of the movable flange 402 is aligned with the connecting hole on the surface of the fixed flange 6. Then, fix it with the double-ended screw 7 and the positioning nut 8.
