Description

Technical Field

[0001] This utility model relates to the field of planetary shaft technology, and specifically to a planetary shaft assembly. Background Technology

[0002] In the field of modern mechanical transmission, planetary shaft assemblies, as key transmission components, are widely used in many fields such as automobiles, aerospace, and industrial equipment. Their performance directly affects the overall operating efficiency and reliability of mechanical equipment. Currently, traditional planetary shaft assemblies face many problems that urgently need to be solved in practical applications. In terms of vibration and noise reduction, traditional planetary shaft assemblies exhibit significant vibration and noise issues during drive shaft operation. This not only reduces the comfort of equipment operation but may also lead to component fatigue damage and shorten the equipment's service life. Regarding impact load handling, when the transmission process encounters sudden impacts, the lack of effective buffering and energy absorption mechanisms can easily damage critical components such as gears, affecting the durability and stability of the planetary shaft assembly. Utility Model Content

[0003] To address the shortcomings of existing technologies, this invention provides a planetary shaft assembly that solves the problems mentioned in the background section.

[0004] The solution to the above-mentioned technical problems provided by this utility model is as follows: A planetary shaft assembly includes a drive shaft to which a nylon base is connected; The nylon base is fitted with a housing via a one-way sleeve. A planetary gear is rotatably mounted on the housing. A nylon gear ring is mounted on the nylon base. A sun gear is mounted at the center of the housing. The nylon gear ring is connected to the sun gear via the planetary gear. A splined shaft is connected to the housing and passes through the nylon base. The splined shaft is connected to a drive shaft.

[0005] Based on the above technical solution, the present invention can be further improved as follows.

[0006] Furthermore, the drive shaft is provided with a single gear, and the drive shaft is driven by meshing with the spline shaft through the single gear.

[0007] The beneficial effects of adopting the above-mentioned further solutions are: This meshing transmission method has a simple structure, reduces intermediate transmission links, and lowers energy loss during transmission, thereby improving transmission efficiency. Simultaneously, the meshing transmission between the single gear and the splined shaft ensures a clear power transmission path, facilitating the control and maintenance of the entire transmission system. This guarantees that power can be stably and efficiently transmitted from the drive shaft to the splined shaft, thus realizing the power transmission function of the entire planetary shaft assembly.

[0008] Furthermore, the outer casing is provided with a pin, and a needle roller gear is mounted on the outside of the pin. The planetary gear is rotatably mounted on the outer casing through the needle roller gear.

[0009] The beneficial effects of adopting the above-mentioned further solutions are: The rolling friction characteristics of needle roller gears result in low frictional resistance when planetary gears rotate on the pin shaft, making rotation more flexible. This mounting method ensures the meshing accuracy between planetary gears and other gears (such as nylon gear rings and sun gears) during operation, reduces energy loss and noise caused by friction and jamming, improves the stability and reliability of the planetary gear transmission system, extends the service life of planetary gears, and thus enhances the performance of the entire planetary shaft assembly.

[0010] Furthermore, the outer surface of the nylon base is provided with a shaped rubber pad.

[0011] The beneficial effects of adopting the above-mentioned further solutions are: The shaped rubber pad has excellent shock absorption and cushioning performance. When the drive shaft is running, it can absorb and buffer some vibrations, reduce noise caused by vibration, and create a relatively stable working environment for the entire planetary shaft assembly. At the same time, when encountering sudden impact loads during transmission, the shaped rubber pad can undergo elastic deformation to absorb some impact energy, reduce the impact force on gears and other components, prevent damage to components due to impact, play a protective role, and improve the durability of the planetary shaft assembly.

[0012] Furthermore, a flat spring is provided on the outside of the pin, and the pin is installed inside the housing by means of the flat spring.

[0013] The beneficial effects of adopting the above-mentioned further solutions are: The flat spring provides a certain preload to the pin, ensuring its stability within the housing and preventing loosening or wobble during operation. This ensures the meshing accuracy between the planetary gears, the nylon ring gear, and the sun gear, maintaining the stable operation of the entire planetary gear transmission system. Furthermore, when the system experiences overload, the flat spring undergoes elastic deformation, relieving pressure on the pin and related components and preventing damage due to overload. This provides overload protection, extends the service life of the planetary shaft assembly, and reduces maintenance costs.

[0014] This invention provides a planetary shaft assembly. It has the following advantages: In this planetary shaft assembly, the planetary gears are rotatably mounted on the housing pins via needle roller gears. The rolling friction characteristics of the needle roller gears result in low frictional resistance and flexible rotation of the planetary gears during operation. Simultaneously, the outer surface of the nylon base is equipped with shaped rubber pads, which possess excellent shock absorption and cushioning properties. When the drive shaft rotates, these shaped rubber pads absorb and buffer some vibrations, reducing noise caused by vibration. Furthermore, the planetary gear transmission system itself features multi-tooth meshing, resulting in more even force distribution compared to ordinary gear transmissions, further reducing impact and noise during transmission, thus achieving a smooth and low-noise transmission effect.

[0015] In the planetary gear transmission mechanism, the nylon gear ring is connected to the sun gear via planetary gears. This multi-gear meshing transmission method makes the power transmission path more direct and efficient. During transmission, the tight meshing between the gears reduces power loss. Simultaneously, the use of a one-way sleeve ensures both flexibility in relative movement and avoids unnecessary energy consumption between the housing and the nylon base. Furthermore, the splined shaft and drive shaft are driven by a single gear. This transmission method has a simple structure, reduces intermediate transmission links, further improves transmission efficiency, and allows power to be transmitted more effectively from the input to the output.

[0016] Planetary gear transmission systems integrate multiple gears into a relatively small space, achieving a compact structure through rational layout and design. This compact structure allows the planetary shaft assembly to complete complex transmission tasks within a limited space. Simultaneously, the planetary gear transmission mechanism features multiple gears participating in transmission simultaneously, enabling the distribution and bearing of large loads. The appropriate materials and structural design of components such as the nylon base and housing further enhance the overall load-bearing capacity of the assembly. Attached Figure Description

[0020] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0021] Please see Figures 1 to 2 As shown, the embodiments provided by this utility model are as follows: Example 1: A planetary shaft assembly includes a drive shaft 1 connected to a nylon base 3. The outer surface of the nylon base 3 is provided with a shaped rubber pad 11. The shaped rubber pad 11 has good shock absorption and buffering performance. When the drive shaft 1 is running, it can absorb and buffer some vibrations, reduce noise caused by vibration, and create a relatively stable working environment for the entire planetary shaft assembly. Meanwhile, when encountering sudden impact loads during transmission, the shaped rubber pad 11 can undergo elastic deformation to absorb some of the impact energy, reduce the impact force on gears and other components, prevent damage to components due to impact, play a protective role, and improve the durability of the planetary shaft assembly. A housing 4 is installed inside the nylon base 3 via a one-way sleeve 12. A planetary gear 6 is rotatably mounted on the housing 4. A nylon gear ring 7 is mounted on the nylon base 3. A sun gear 8 is installed at the center of the housing 4. The nylon gear ring 7 is connected to the sun gear 8 via the planetary gear 6. A splined shaft 13 is connected to the housing 4 and passes through the nylon base 3. The splined shaft 13 is connected to the transmission shaft 1. A single gear 2 is provided on the transmission shaft 1. The transmission shaft 1 is driven by the splined shaft 13 through the meshing of the single gear 2. This meshing transmission method has a simple structure, reduces intermediate transmission links, reduces energy loss during transmission, and thus improves transmission efficiency. Meanwhile, the meshing transmission between the single gear 2 and the spline shaft 13 makes the power transmission path clear, which facilitates the control and maintenance of the entire transmission system and ensures that the power can be transmitted stably and efficiently from the transmission shaft 1 to the spline shaft 13, thereby realizing the power transmission function of the entire planetary shaft assembly.

[0022] Example 2: To further optimize the transmission performance and operational stability of the planetary shaft assembly, for example, such as... Figures 1 to 2As shown, this utility model also includes: a pin 10 on the outer casing 4, a needle roller gear 9 mounted on the outer side of the pin 10, and a planetary gear 6 rotatably mounted on the outer casing 4 via the needle roller gear 9. The rolling friction characteristics of the needle roller gear 9 result in low frictional resistance and more flexible rotation of the planetary gear 6 when rotating on the pin 10. This mounting method ensures the meshing accuracy between the planetary gear 6 and other gears (such as the nylon gear ring 7 and the sun gear 8) during operation, reduces energy loss and noise caused by friction and jamming, improves the stability and reliability of the planetary gear 6 transmission system, extends the service life of the planetary gear 6, and thus improves the performance of the entire planetary shaft assembly. A flat spring 5 is provided on the outer side of the pin 10, and the pin 10 is mounted inside the outer casing 4 via the flat spring 5. The flat spring 5 provides a certain preload to the pin 10, ensuring the stability of the pin 10 mounted inside the outer casing 4 and preventing the pin 10 from loosening or shaking during operation. This ensures the meshing accuracy between the planetary gear 6 and the nylon gear ring 7 and the sun gear 8, and maintains the stable operation of the entire planetary gear 6 transmission system. In addition, when the system is overloaded, the flat spring 5 can undergo a certain elastic deformation to relieve the pressure of the overload on the pin 10 and related components, avoid damage to the components caused by overload, play the role of overload protection, extend the service life of the planetary shaft assembly, and reduce maintenance costs.

[0023] Working principle: Power is transmitted to drive shaft 1, and drive shaft 1 begins to rotate. During the rotation of drive shaft 1, on one hand, drive shaft 1 transmits power to spline shaft 13 through the meshing of a single gear 2. Since spline shaft 13 passes through nylon base 3 and is connected to drive shaft 1, spline shaft 13 rotates accordingly. On the other hand, drive shaft 1 is also connected to nylon base 3, causing nylon base 3 to move along with it.

[0024] A nylon gear ring 7 is mounted on the nylon base 3, and a sun gear 8 is mounted at the center of the outer casing 4. A planetary gear 6 is rotatably mounted on the outer casing 4, and the nylon gear ring 7 is connected to the sun gear 8 via the planetary gear 6. When the nylon base 3 moves with the drive shaft 1, the nylon gear ring 7 also rotates, thereby driving the sun gear 8 to rotate via the planetary gear 6.

[0025] A pin 10 is mounted on the outer casing 4, and the planetary gear 6 is rotatably mounted on the pin 10 of the outer casing 4 via a needle roller gear 9. This mounting method allows the planetary gear 6 to rotate flexibly on the pin 10, ensuring the normal operation of the planetary gear 6 transmission system. Simultaneously, a flat spring 5 is provided on the outer side of the pin 10, and the pin 10 is mounted inside the outer casing 4 via the flat spring 5. The function of the flat spring 5 is to provide a certain preload, ensuring the stability of the pin 10 installation and preventing the pin 10 from loosening or shaking during operation, thereby ensuring the meshing accuracy between the planetary gear 6 and the nylon gear ring 7 and sun gear 8, and maintaining the stable operation of the entire planetary gear 6 transmission system. The splined shaft 13 rotates under the drive of the transmission shaft 1. The splined shaft 13 is connected to external equipment, thereby outputting power to the external equipment and realizing the power transmission function of the entire planetary shaft assembly.
