[0024] 1. The present application significantly improves the maintenance efficiency and economy of the speed reducer by setting a lubricating mechanism. The lubricating mechanism adopts an innovative structural design, which can realize rapid lubricating oil filling without disassembling the complex rotating assembly system during large-area maintenance operation. This design breakthrough brings multiple significant advantages: first, the maintenance time can be greatly shortened, greatly improving the equipment availability; second, the cumbersome disassembly process in traditional maintenance is eliminated, reducing the operation and maintenance labor cost; more importantly, it creates considerable economic benefits for enterprises. In addition, the lubricating mechanism can also realize more accurate oil quantity control, avoid energy waste caused by excessive lubrication, and at the same time ensure that each connecting component obtains uniform and sufficient lubrication protection, thereby prolonging the service life of the key components and further reducing the total life cycle cost of the equipment. This non-invasive maintenance method also effectively avoids the risk of component damage caused by frequent disassembly, significantly improving the operation reliability of the equipment. In summary, this innovative design optimizes the maintenance process, reduces operation and maintenance costs, and provides an efficient solution for intelligent maintenance of large mechanical equipment.

[0025] 2. The present application fundamentally optimizes the transmission structure of the speed reducer by innovatively setting a connecting component and scientifically arranging it between the fixed component and the rotating component. This design revolutionizes the traditional direct arc surface contact method into an advanced spherical surface contact method, achieving multiple significant technical advantages: the spherical surface contact structure greatly reduces the friction resistance between the rotating component and the fixed component, which is tested to reduce the rotating friction, effectively improving the transmission efficiency and reducing energy loss. Second, the optimized contact method significantly improves the motion accuracy of the speed reducer, enabling transmission error to be controlled, in addition, the innovative design of the connecting component also brings a longer service life of the equipment. Since the spherical surface contact can uniformly disperse the load and reduce local wear, the service life of the key components is improved, reducing the equipment replacement frequency and maintenance cost. At the same time, the optimized friction characteristics make the speed reducer run more smoothly, reducing vibration and noise, and improving the reliability and environmental friendliness of the overall system.

[0039] like Figures 1-9 As shown, the precision modular rotary reducer includes a base 1, a drive unit 2, a fixed component 3, a rotating component 4, a connecting component 5, and a lubrication mechanism 6.

[0040] The drive part 2 is installed on the side of the base 1. The drive part 2 includes a worm that drives the rotating component 4 to rotate, and a motor that drives the worm to rotate. The drive part 2 can rotate in cooperation with the rotating component 4 and lock the rotating component 4 under the self-locking principle of the worm wheel and worm.

[0041] The fixing component 3 is installed inside the base 1. The fixing component 3 is detachable. During daily use, it is fixedly installed inside the base 1. If it is necessary to replace the connecting component 5 or to inspect its internal parts, the fixing component 3 can be removed for easy inspection.

[0042] The rotating component 4 is installed inside the base 1. The rotating component 4 rotates under the drive of the drive part 2, thereby precisely steering the device installed on the rotating component 4. Due to the self-locking principle of the worm gear, when an external force pushes the device installed on the rotating component 4, it cannot turn the rotating component 4.

[0043] The connecting component 5 is installed between the fixed component 3 and the rotating component 4. The connecting component 5 is used to improve the direct contact between the inner side of the rotating component 4 and the outer side of the fixed component 3, thereby reducing rotational friction and improving the accuracy of the device.

[0044] The lubricating mechanism 6 is installed on the upper surface of the fixed assembly 3, and the lubricating mechanism 6 is detachably installed. Before the device is installed for the first time, or when the lubricating oil is refilled for maintenance, the rotating assembly 4 is rotated to a suitable position, i.e. when the inner trigger ring 37 and the outer trigger ring 47 are combined, and then the lubricating mechanism 6 is installed on the upper surface of the fixed assembly 3 to perform maintenance work.

[0045] The rotating assembly 4 is driven by the driving part 2 to rotate, and the connecting assembly 5 reduces the friction between the rotating assembly 4 and the fixed assembly 3 during rotation.

The inner fixed groove 35 is opened at the center line of the inner sliding groove 34, and is used to accommodate the limiting ring 52 in the connecting assembly 5, thereby avoiding the movement of the limiting ring 52 and further improving the movement accuracy. The inner lubricating groove 36 is opened on the upper surface of the fixed ring 31, and is used to refill lubricating oil in the vertical direction of the connecting assembly 5 after the lubricating mechanism 6 is installed. The inner trigger ring 37 is installed on the periphery of the inner lubricating groove 36, and the inner trigger ring 37 and the outer trigger ring 47 are concentrically arranged and do not interfere with each other when the rotating assembly 4 rotates. When the inner trigger ring 37 and the outer trigger ring 47 operate to the same center, a complete trigger ring can be formed to press the control disc 647 in the control assembly 64, so that the oil passage is unobstructed. This design avoids the waste of lubricating oil in the lubricating mechanism 6.
