[0001] The utility model belongs to the technical field of reducers, and in particular relates to a high-precision reducer for a highly intelligent robot joint. Background Art

[0002] With the rapid development of industrial automation, robotics technology has been widely used. As the core component of robot movement, the accuracy and stability of robot joints are crucial to the overall performance of the robot. Therefore, the development of a highly intelligent and high-precision robot joint reducer has become an urgent need in the industry.

[0003] Secondly, the traditional robot joint reducer has many deficiencies in the lubrication system. For example, the lubrication method is not efficient and uniform, which can easily lead to uneven wear of the gear set, thus affecting the service life and accuracy of the reducer. In addition, the traditional reducer also has certain limitations in transmission design, and it is difficult to achieve comprehensive and uniform lubrication of each gear. For this reason, we propose a highly intelligent robot joint high-precision reducer to solve the above problems. Utility Model Content

[0011] Preferably, a driving motor is installed on the top of the connecting seat, and the top end of the output shaft of the driving motor is fixed to the adjacent driving wheel.

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

[0013] 1. The device is exquisitely designed. By integrating key components such as oil pump, oil pipe connector, oil supply tank, oil drip assembly, etc., it realizes efficient lubrication of the gear set in the reducer. The oil pump and oil pipe connector adopt shaft seal design to ensure the reliability of the rotation connection, effectively prevent the occurrence of oil leakage, and improve the safety and stability of the overall operation.

[0014] 2. The oil dripping assembly in the device filters the oil entering the oil supply pipe through the setting of the filter screen, ensuring the purity of the oil and reducing the wear of the gear set by impurities, thereby extending the service life of the reducer.

[0015] 3. The device also adopts a belt drive design, which drives the drive wheel to rotate through the drive motor, and then drives the drive belt and the oil drip assembly to circulate inside the reducer. This design ensures that each gear can be covered with lubricating oil, improving the uniformity and comprehensiveness of lubrication. At the same time, the setting of multiple auxiliary drive wheels enhances the stability and positioning accuracy of the drive belt, and effectively prevents the deviation of the drive belt.

[0016] In summary, the high-precision reducer for high-intelligence robot joints improves the operating efficiency and stability of the reducer, extends its service life, and provides a strong guarantee for the high-precision movement of the robot joints by optimizing the lubrication system and transmission design.

[0025] In this embodiment, a top cover 4 is installed on the top of the reducer housing 1, and the connecting seat 5 and the top cover 4 are located at the same level.

[0026] In this embodiment, an oil collecting box 3 is installed at the bottom of the reducer housing 1 , and the oil collecting box 3 is connected to the bottom of the inner wall of the reducer housing 1 .

[0027] In this embodiment, the oil supply assembly 7 includes an oil supply tank 71, the top of the oil supply tank 71 is connected to an oil pump 72, the top of the oil pump 72 is rotatably connected to an oil pipe connector 73, the top of the oil pipe connector 73 is connected to two connecting hoses 6, and the two connecting hoses 6 are respectively connected to two oil dripping assemblies 8.

[0028] In this embodiment, a shaft seal is provided at the rotational connection position between the oil pump 72 and the oil pipe connector 73 .

[0029] In this embodiment, the oil dripping assembly 8 includes an oil supply pipe 81, the interior of the oil supply pipe 81 is slidably connected to a support pipe 82, a plurality of filter screens 83 are installed on the support pipe 82, the bottom of the oil supply pipe 81 is connected to a nozzle 84, and the top of the oil supply pipe 81 is connected to the adjacent connecting hose 6.

[0030] In this embodiment, a driving motor 93 is installed on the top of the connecting seat 5 , and the top end of the output shaft of the driving motor 93 is fixed to the adjacent driving wheel 92 .

[0031] Furthermore, a shaft seal is used at the rotational connection portion between the oil pump 72 and the oil pipe connector 73, which can prevent oil leakage from occurring at the connection portion between the oil pump 72 and the oil pipe connector 73 while maintaining rotation.

[0032] Working principle and use process of the utility model: When the whole device is used, first install the reducer internal gear set 2 on the reducer housing 1, then put in the top cover 4 and the connecting seat 5 and weld or clamp it with the reducer housing 1, then fill the oil supply tank 71 with oil, connect the two ends of the oil pipe connector 73 to the connecting hose 6 respectively, and then connect the other ends of the two connecting hoses 6 to the top of the oil supply pipe 81 in the oil drip assembly 8;

[0033] Then, the oil pump 72 is started. After the oil pump 72 draws oil from the oil supply tank 71, the oil enters the oil supply pipe 81 through the oil pipe connector 73 and the connecting hose 6. The oil in the oil supply pipe 81 is filtered through the multiple filter screens 83 on the support pipe 82 and then slowly leaks to the gear set 2 inside the reducer through the nozzle 84. After lubricating the gear set 2 inside the reducer, the oil leaks into the oil collecting box 3 through the bottom of the reducer housing 1 for recovery. After the oil collecting box 3 is recovered, the oil can be poured back into the reducer housing 1 after the oil is opened to access the oil, thereby forming a recycling of the lubricating oil.
