Description

Technical Field

[0001] This utility model relates to the field of planetary gear technology, and in particular to a planetary gear transmission synchronization device. Background Technology

[0002] In planetary gear transmission synchronization devices, the tightness of gear meshing and the positional stability of planetary gears are the core prerequisites for ensuring the synchronous transmission accuracy of the device. These devices are widely used in equipment requiring high-precision power transmission. During operation, the meshing relationship between the sun gear, planetary gears, and ring gear directly determines the power transmission efficiency, while the stable movement of the planetary gears around the sun gear affects the load distribution effect. With long-term operation, the gear teeth will experience natural wear due to continuous meshing, and the positioning structure of the planetary gears will be affected by vibration, load fluctuations, and other factors, leading to gradual changes in the original meshing state and positional accuracy. The core requirement for these devices in the industry is to maintain stable meshing and positioning through the device's own operating mechanism without additional intervention, adapting to long-term continuous operation conditions and avoiding the impact of transmission deviations on the overall performance of the equipment.

[0003] Current planetary gear transmission synchronization devices, when faced with increased meshing backlash due to gear wear, often require shutdown and manual disassembly to restore meshing accuracy by replacing components or manual adjustment. This process not only interrupts production but may also introduce new accuracy deviations due to variations in human operation. Regarding radial misalignment of planetary gears, existing structures rely solely on positioning components during initial installation to limit displacement. Over long-term use, these positioning components are susceptible to wear or vibration failure, causing planetary gears to deviate from their preset paths. This leads to uneven stress on multiple planetary gear sets, exacerbating gear wear and reducing transmission synchronization. These problems all require external power or manual intervention to alleviate, and cannot be dynamically adjusted by the device itself, making them unsuitable for applications requiring high stability and low maintenance.

[0004] Therefore, a new planetary gear transmission synchronization device is proposed to solve the above problems. Utility Model Content

[0005] 1. Technical problems to be solved

[0006] The purpose of this invention is to provide a planetary gear transmission synchronization device that solves the problem that in practical use, current planetary gear transmission synchronization devices, when faced with increased meshing clearance due to gear wear, often require shutdown and manual disassembly of the device to restore meshing accuracy by replacing components or manual adjustment. This process not only interrupts the production flow but may also introduce new accuracy deviations due to differences in manual operation. Furthermore, regarding radial misalignment of planetary gears, existing structures rely solely on positioning components during initial installation to limit displacement. Over long-term use, these positioning components are prone to wear or vibration failure, causing planetary gears to deviate from their preset trajectory. This leads to uneven stress on multiple planetary gears, exacerbating gear wear and reducing transmission synchronization. These problems all require external power or manual intervention to alleviate, and cannot be dynamically adjusted by the device itself, making them unsuitable for applications requiring high stability and low maintenance.

[0007] 2. Technical Solution

[0008] To solve the above-mentioned technical problems, this utility model is achieved through the following technical solution:

[0009] This utility model relates to a planetary gear transmission synchronization device, comprising a mounting ring having multiple second connecting holes. A mounting cylinder is fixedly installed in any one of the second connecting holes. A sliding rod is installed in any one of the mounting cylinders. A spring is installed at the end of each sliding rod closest to the mounting cylinder. The other end of each spring is connected to the bottom end of the inner sidewall of the corresponding mounting cylinder. A mounting plate is installed at the end of each sliding rod furthest from the corresponding mounting cylinder. A bearing is installed at the top of each mounting plate. A rotating shaft is installed at the other end of each bearing. A planetary gear is installed at the top of each rotating shaft. A sun gear is installed between the multiple planetary gears, and the sun gear meshes with any one of the planetary gears.

[0010] Furthermore, each of the mounting plates has a mounting block installed at its bottom end, and a base plate is installed at the bottom end of the mounting block. A first sliding groove is provided on the base plate, and multiple first sliders are installed in the first sliding groove. The upper end of each first slider is connected to the bottom end of the corresponding mounting block. This design can reduce the downward pressure on the sliding rod by connecting the first sliders and the mounting blocks, preventing excessive wear and further increasing the service life of the device.

[0011] Furthermore, each of the first sliders is cylindrical, and the diameter of each of the first sliders is smaller than the length between the outer diameter and the inner diameter of the first sliding groove. This design allows the first slider to move radially within the first sliding groove.

[0012] Furthermore, a first connecting hole is provided on the base plate, and a drive shaft is installed through the first connecting hole. The top end of the drive shaft is connected to the bottom end of the sun gear. A motor is installed at the end of the drive shaft away from the sun gear. The upper end of the motor is connected to the lower end of the base plate. This design allows the motor to drive the sun gear to rotate through the drive shaft, and the sun gear to further drive multiple planet gears to rotate, thus forming a complete power transmission.

[0013] Furthermore, each of the mounting cylinders has a symmetrical second sliding groove on its inner sidewall, a second slider is installed in each of the second sliding grooves, and each of the second sliders is connected to a corresponding sliding rod. This design can effectively reduce the stress on the sliding rod in the mounting cylinder and reduce its wear.

[0014] Furthermore, four first supports are installed at the bottom end of the base plate, and three second supports are symmetrically installed at the top end of the base plate. A planetary carrier is installed at the upper end of the second supports. A third sliding groove is opened on the planetary carrier, and a tooth groove is opened at the top of the inner side wall of the third sliding groove. The teeth of any planetary gear mesh with the tooth groove.

[0015] Furthermore, an oil injection hole is provided on the upper surface of the planetary carrier. The oil injection hole passes through the planetary carrier and connects to the third sliding groove. This design allows lubricating oil to be injected into the third sliding groove inside the planetary carrier through the oil injection hole, so that the lubricating oil comes into contact with one of the planetary gears. When the planetary gear revolves around the sun gear, the lubricating oil is evenly coated on the entire inner wall of the third sliding groove, so that the other planetary gears can also get sufficient lubrication, reducing their wear with the planetary carrier and increasing the service life of the device.

[0016] 3. Beneficial effects

[0017] Compared with existing technologies, the advantages of this utility model are:

[0018] This planetary gear transmission synchronization device, relying on its own motion characteristics during operation, simultaneously resolves the problems of increased gear meshing clearance and radial misalignment of planetary gears without requiring additional power or manual adjustment, significantly improving the device's practicality and reliability. During operation, its own motion drives related structures to dynamically compensate for gear meshing clearance, preventing a decrease in transmission accuracy due to wear, ensuring stable and efficient power transmission, and reducing equipment failures caused by clearance issues. Simultaneously, the constraint mechanism formed by its own motion effectively limits the radial misalignment of the planetary gears, maintaining a stable trajectory of the planetary gears around the sun gear, ensuring even load distribution across multiple planetary gear sets, reducing the wear rate of local gears, and extending the overall service life of the device. Furthermore, the requirement for no downtime maintenance or manual intervention reduces equipment downtime, improves production efficiency, and is suitable for long-term, continuous, and high-precision transmission needs.

[0019] Of course, any product implementing this utility model does not necessarily need to achieve all of the advantages described above at the same time. Attached Figure Description

Furthermore, the schematic diagrams are merely examples and should not limit the scope of protection of this utility model.

[0031] To make the objectives, technical solutions, and advantages of this utility model clearer, the embodiments of this utility model will be described in further detail below with reference to the accompanying drawings.

[0032] Please see Figure 1-5 As shown, this embodiment is a planetary gear transmission synchronization device, including a mounting ring 210. The mounting ring 210 has multiple second connecting holes 220. A mounting cylinder 310 is fixedly installed in any one of the second connecting holes 220. A sliding rod 311 is installed in any one of the mounting cylinders 310. A spring 312 is installed at the end of each sliding rod 311 near the mounting cylinder 310. The other end of each spring 312 is connected to the bottom end of the inner wall of the corresponding mounting cylinder 310. A mounting plate 330 is installed at the end of each sliding rod 311 away from the corresponding mounting cylinder 310. A bearing 331 is installed at the top of each mounting plate 330. A rotating shaft 332 is installed at the other end of each bearing 331. A planetary gear 410 is installed at the top of each rotating shaft 332. A sun gear 420 is installed between the multiple planetary gears 410. Wheel 420 meshes with any one of the planetary gears 410; a mounting block 333 is mounted on the bottom end of any mounting plate 330, and a base plate 110 is mounted on the bottom end of the mounting block 333. A first sliding groove 130 is provided on the base plate 110, and a plurality of first sliders 334 are installed in the first sliding groove 130. The upper end of any one of the first sliders 334 is connected to the bottom end of the corresponding mounting block 333; each of the first sliders 334 is cylindrical, and the diameter of each of the first sliders 334 is smaller than the length between the outer diameter and the inner diameter of the first sliding groove 130; a first connecting hole 140 is provided on the base plate 110, and a drive shaft 430 is installed through the first connecting hole 140. The top end of the drive shaft 430 is connected to the bottom end of the sun gear 420, and a motor 440 is installed on the end of the drive shaft 430 away from the sun gear 420. The upper end of the motor 440 is connected to the lower end of the base plate 110. Each of the mounting cylinders 310 has a symmetrical second sliding groove 320 on its inner sidewall, and each of the second sliding grooves 320 has a second slider 321 installed in it. Each of the second sliders 321 is connected to the corresponding sliding rod 311.

[0033] Working principle: In use, the motor 440 is started first. The motor 440 drives the sun gear 420 to rotate through the transmission shaft 430. The sun gear 420 further drives multiple planetary gears 410 to rotate, forming a complete power transmission. During operation, the planetary gears 410 and the sun gear 420 will inevitably experience some wear. After a long period of use, the gaps will increase, making the meshing less tight. This causes the planetary gears 410 to deviate from the preset trajectory, resulting in uneven force on multiple sets of planetary gears 410, which aggravates gear wear and reduces transmission synchronization. At this time, the spring 312 of the corresponding mounting cylinder 310 will push the corresponding sliding rod 311 towards the sun gear 420 through its own elastic potential energy. When the sliding rod 311 moves, it drives the bearing 331 to move towards the center through the mounting plate 330. When the bearing 331 moves, it drives the corresponding planetary gear 410 to move towards the center through the rotating shaft 332, making the corresponding planetary gear 410 and the sun gear 420 more tightly engaged.

[0034] Four first supports 120 are installed at the bottom of the base plate 110. Three second supports 150 are symmetrically installed at the top of the base plate 110. A planetary carrier 160 is installed on the top of the second supports 150. The planetary carrier 160 has a third sliding groove, and a toothed groove is formed at the top of the inner sidewall of the third sliding groove. The teeth of any planetary gear 410 mesh with the toothed groove. An oil injection hole 170 is formed on the upper surface of the planetary carrier 160, and the oil injection hole 170 passes through the planetary carrier 160 and connects to the third sliding groove.

[0035] Working principle: Lubricating oil can be injected into the third sliding groove in the planet carrier 160 through the oil injection hole 170, so that the lubricating oil comes into contact with one of the planet gears 410. When the planet gear 410 revolves around the sun gear 420, the lubricating oil is evenly coated on the entire inner wall of the third sliding groove, so that the other planet gears 410 can also get sufficient lubrication, reducing their wear with the planet carrier 160 and increasing the service life of the device.
