Description

Technical Field

[0001] This invention relates to the field of engineering machinery technology, and in particular to a planetary carrier, transmission device, power system and working machinery. Background Technology

[0002] As a core transmission component of construction machinery, the speed reducer mainly transmits the driving force of the motor and enables the working device of the construction machinery to work by reducing speed and increasing torque. In order to ensure the normal operation of all rotating parts inside the speed reducer, especially since construction machinery is subject to heavy loads and large impacts, it is necessary to ensure lubrication between the moving parts.

[0003] Currently, speed reducers in construction machinery mainly rely on oil immersion lubrication and churning splash lubrication. Moving parts below the lubricating oil level are lubricated by oil immersion, while moving parts above the lubricating oil level are lubricated by churning splash lubrication of bearings. However, because lubricating oil requires space for thermal expansion and to reduce churning losses, the lubricating oil inside the speed reducer is generally filled to between 1 / 2 and 3 / 4. This results in 1 / 4 to 1 / 2 of the parts moving above the lubricating oil level. Lubrication of these parts is particularly important, as poor lubrication can lead to the failure of the entire speed reducer. Therefore, optimizing the lubrication state of moving parts above the lubricating oil level can significantly improve the operating performance and service life of the speed reducer.

[0004] In the prior art, for travel reducers and winch reducers with the tooling in a horizontally placed state, since the sun gear, planet gears, planet carriers and gear ring inside the reducer are all in a state of relative motion, each part is in a periodic state of oil immersion lubrication and oil splash lubrication. When the part is in the oil splash lubrication stage, it is difficult for this part to be fully lubricated. It is necessary to achieve active lubrication or add a complex mechanism, which increases the lubrication cost. Summary of the Invention

[0005] This invention provides a planetary carrier, transmission device, power system, and working machinery to solve the problem in the prior art for horizontally placed travel reducers and winch reducers. Because the sun gear, planet gears, planetary carrier, and ring gear inside the reducer are in relative motion, each part is in a periodic state of oil immersion lubrication and oil splash lubrication. When the parts are in the oil splash lubrication stage, it is difficult to fully lubricate these parts. Active lubrication or the addition of complex mechanisms is required to achieve this, which increases the lubrication cost.

[0006] This invention provides a planetary carrier, comprising:

[0007] First side panel;

[0008] The second side plate is arranged parallel to the first side plate, and a space is left between the first side plate and the second side plate for installing the planetary gear and the sun gear;

[0009] At least one web plate is located within the space. The two ends of the web plate are respectively connected to the first side plate and the second side plate, and an oil storage tank is provided on the web plate. The opening of the oil storage tank faces the radial outer end of the planetary carrier.

[0010] According to a planetary carrier provided by the present invention, the web includes a first connecting plate and a second connecting plate connected to the first connecting plate, the first connecting plate and the second connecting plate are arranged at an angle, and the oil storage groove is formed between the first connecting plate and the second connecting plate.

[0011] According to a planetary carrier provided by the present invention, the diameter of the circle containing the radial outer end of the web is smaller than the diameters of the first side plate and the second side plate.

[0012] According to a planetary carrier provided by the present invention, the web plate and the planetary gears are spaced apart.

[0013] According to a planetary carrier provided by the present invention, the web plate is integrally formed with the first side plate and the second side plate.

[0014] The present invention also provides a transmission device, comprising:

[0015] Planetary carriage as described in any of the above;

[0016] Multiple planetary gears are respectively connected to the first and second side plates of the planet carrier via planetary shafts;

[0017] The sun gear is located between and meshes with the planet gears.

[0018] According to a transmission device provided by the present invention, the planetary gear is rotatably connected to the planetary shaft via a bearing, the planetary gear is provided with at least one first oil hole, and the outer ring of the bearing is provided with at least one second oil hole, the first oil hole and the second oil hole being connected to each other.

[0019] According to a transmission device provided by the present invention, a third oil hole is provided on the web of the planetary carrier, the third oil hole is connected to the oil storage tank of the planetary carrier, and the third oil hole can correspond to the second oil hole.

[0020] The present invention also provides a power system, including a planetary carrier as described in any one of the preceding claims or a transmission device as described in any one of the preceding claims.

[0021] The present invention also provides a working machine, including a planetary carrier as described in any one of the above claims, a transmission device as described in any one of the above claims, or a power system as described in the above claims.

[0022] The planetary carrier, transmission device, power system, and working machinery provided by this invention include a first side plate, a second side plate, and at least one web plate. The first and second side plates are arranged parallel to each other, with a space between them for mounting planet gears and a sun gear. The web plate is located within this space, and its two ends are connected to the first and second side plates respectively, serving to connect and support the first and second side plates to ensure the planetary carrier maintains rigidity under stress. Furthermore, an oil reservoir may be provided on the web plate, with the opening of the reservoir facing the radially outer end of the planetary carrier.

[0023] When the planetary carrier rotates to a position below the lubricating oil level, some lubricating oil flows into the oil reservoir, where it is stored. When the planetary carrier rotates above the lubricating oil level, the lubricating oil stored in the reservoir gradually flows out with the rotation of the planetary carrier, dripping onto the planetary gears above the lubricating oil level, as well as the sun gear and ring gear that mesh with the planetary gears. This effectively lubricates the planetary gears, sun gear, and ring gear above the lubricating oil level, ensuring that all areas requiring lubrication, whether below or above the lubricating oil level, receive adequate lubrication. This contributes to improving the operating performance and service life of the reducer. The planetary carrier has a simple structure, allowing a single planetary carrier to complete the lubrication of the meshing parts above the lubricating oil level. It provides excellent lubrication and effectively optimizes the lubrication state of the internal components of the reducer. Attached Figure Description

In addition, the terms "first," "second," and "third" are used for descriptive purposes only and should not be construed as indicating or implying relative importance.

[0039] In the description of the embodiments of the present invention, it should be noted that, unless otherwise explicitly specified and limited, the terms "connected" and "linked" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium.

In this specification, the illustrative expressions of the above terms do not necessarily refer to the same embodiment or example. Furthermore, the specific features, structures, materials, or characteristics described may be combined in any suitable manner in one or more embodiments or examples. Moreover, without contradiction, those skilled in the art can combine and integrate the different embodiments or examples described in this specification, as well as the features of different embodiments or examples.

[0042] The following is combined Figures 1 to 7 The planetary carrier, transmission device, power system, and working machinery of the present invention are described.

[0043] The present invention provides a planetary carrier, which may include a first side plate 1, a second side plate 2 and at least one web plate 3.

[0044] The first side plate 1 and the second side plate 2 are arranged in parallel, and space can be left between the first side plate 1 and the second side plate 2 for installing the planetary gear 4 and the sun gear.

[0045] The web plate 3 is located in the space, and the two ends of the web plate 3 can be connected to the first side plate 1 and the second side plate 2 respectively, so as to connect and support the first side plate 1 and the second side plate 2, so as to ensure that the planetary carrier remains rigid after being subjected to force.

[0046] In addition, an oil storage tank 6 can be provided on the web plate 3, and the opening of the oil storage tank 6 can face the radial outer end of the planet carrier.

[0047] During the operation of the planetary carrier, when the planetary carrier makes an overall rotational motion, it will rotate from the area below the lubricating oil surface to the area above the lubricating oil surface, and then rotate back to the area below the lubricating oil surface, and this process will repeat.

[0048] When the planetary carrier rotates to the area below the lubricating oil level, some lubricating oil flows into the oil reservoir 6, where it is stored. When the planetary carrier rotates above the lubricating oil level, the lubricating oil stored in the oil reservoir 6 gradually flows out as the planetary carrier rotates, dripping onto the planetary gears 4 above the lubricating oil level, as well as the sun gear and ring gear that mesh with the planetary gears 4. This effectively lubricates the planetary gears 4, sun gear, and ring gear above the lubricating oil level, ensuring that all areas requiring lubrication, whether below or above the lubricating oil level, receive adequate lubrication. This is beneficial for improving the operating performance and service life of the reducer.

[0049] In an optional embodiment of the present invention, the web 3 may include a first connecting plate 31 and a second connecting plate 32, wherein the first connecting plate 31 and the second connecting plate 32 are connected, and the first connecting plate 31 and the second connecting plate 32 may be arranged at an included angle. This improves the rigidity of the web 3, thereby increasing its load-bearing capacity and thus enhancing the rigidity of the planetary carrier.

[0050] Here, the two ends of the first connecting plate 31 can be connected to the first side plate 1 and the second side plate 2 respectively, and the two ends of the second connecting plate 32 can be connected to the first side plate 1 and the second side plate 2 respectively.

[0051] Specifically, the first connecting plate 31 and the second connecting plate 32 can form an L-shaped structure, that is, the web plate 3 can be L-shaped. In this way, by replacing the triangular structure with the L-shaped web plate 3, the overall weight of the planetary carrier can be reduced, the manufacturing cost can be lowered, the load-bearing capacity of the web plate 3 can be maintained, and the internal shrinkage defects that occur in the triangular structure during the casting process can be reduced, and the casting difficulty can be reduced.

[0052] Furthermore, an oil storage tank 6 can be formed between the first connecting plate 31 and the second connecting plate 32. This not only enables the web plate 3 to have an oil storage function, but also reduces the processing difficulty and processing cost.

[0053] In an optional embodiment of the present invention, the diameter of the circle containing the radial outer end of the web 3 can be smaller than the diameter of the first side plate 1 and the second side plate 2. This prevents the web 3 from protruding radially from the planetary gear 4 along the planet carrier, ensuring that the lubricating oil flowing from the oil reservoir 6 can drip onto the planetary gear 4, thereby lubricating the planetary gear 4 above the lubricating oil level.

[0054] It should be noted that the radial direction here refers to the radial direction of the planet carrier.

[0055] In an optional embodiment, the web plate 3 and the planetary gears 4 can be arranged at intervals to ensure the stability of the planet carrier.

[0056] In an optional embodiment, the web 3, the first side plate 1, and the second side plate 2 can be an integral structure. This can effectively improve the stability of the connection between the web 3 and the first side plate 1 and the second side plate 2, thereby improving the stiffness and stability of the planetary carrier.

[0057] Here, the web plate 3, the first side plate 1, and the second side plate 2 can be cast as a single structure.

[0058] The planetary carrier provided by this invention can be used in planetary reducers of engineering machinery. The planetary carrier has a simple structure and can complete the lubrication of the meshing parts in the area above the lubricating oil surface with a single planetary carrier. The oil storage groove 6 on the web plate 3 of the planetary carrier can complete the inflow, storage and outflow of lubricating oil as the planetary carrier rotates, resulting in good lubrication effect and effectively optimizing the lubrication state of the internal parts of the reducer. The oil storage groove 6 on the planetary carrier is cast with the web plate 3 of the planetary carrier, which does not require additional processing, resulting in low manufacturing cost. In addition, the L-shaped web plate 3 is lightweight, has high structural strength, and can reduce the internal shrinkage defects of the cast triangular web plate.

[0059] The transmission device provided by the present invention is described below. The transmission device described below can be referred to in correspondence with the planetary carrier described above.

[0060] The present invention provides a transmission device that may include a planet carrier, multiple planet gears 4 and a sun gear.

[0061] Among them, multiple planetary gears 4 can be connected to the first side plate 1 and the second side plate 2 of the planet carrier through planetary shafts, respectively. The sun gear is located among the multiple planetary gears 4, and the sun gear can mesh with the multiple planetary gears 4.

[0062] Here, the planet carrier can be a planet carrier as described in any of the above embodiments.

[0063] The beneficial effects achieved by the transmission device provided by this invention are consistent with those achieved by the planetary carrier provided by this invention. When the planetary carrier rotates to the area below the lubricating oil level, some lubricating oil will flow into the oil storage tank 6 of the planetary carrier, where it will store this portion of lubricating oil. When the planetary carrier rotates to the area above the lubricating oil level, the lubricating oil stored in the oil storage tank 6 will gradually flow out as the planetary carrier rotates, dripping onto the planetary gears 4 above the lubricating oil level, as well as the sun gear and ring gear that cooperate with the planetary gears 4. This allows for lubrication of the planetary gears 4, sun gear, and ring gear above the lubricating oil level, effectively ensuring that the areas requiring lubrication, whether below or above the lubricating oil level, are effectively lubricated. This is beneficial for improving the operating performance and service life of the transmission device.

[0064] In an optional embodiment, the first side plate 1 and / or the second side plate 2 may be provided with through holes for the drive shaft connected to the sun gear to pass through. This facilitates the connection between the sun gear and the drive shaft of the drive device.

[0065] In an optional embodiment of the present invention, the planetary gear 4 can be rotatably connected to the planetary shaft via a bearing, thereby realizing the rotatable connection between the planetary gear 4 and the planet carrier.

[0066] Among them, such as Figure 6 and Figure 7 As shown, at least one first oil hole 41 can be provided on the planetary gear 4, and at least one second oil hole can be provided on the outer ring of the bearing, and the first oil hole 41 and the second oil hole can be connected to each other. In this way, lubricating oil can flow into the second oil hole through the first oil hole 41 and lubricate the bearing through the second oil hole, thereby effectively improving the lubrication effect on the planetary gear 4 and the bearing, and further improving the operating performance and service life of the transmission device.

[0067] like Figure 7 As shown, the planetary gear 4 can be provided with four first oil holes 41, and the outer ring of the bearing can be provided with four second oil holes. The four first oil holes 41 are respectively connected to the four second oil holes, which facilitates the entry of lubricating oil into the bearing and thus improves the lubrication effect of the bearing.

[0068] In an optional embodiment, both the first side plate 1 and the second side plate 2 of the planetary carrier may be provided with a plurality of mounting holes 5 for mounting planetary shafts.

[0069] In an optional embodiment of the present invention, a third oil hole may be provided on the web 3 of the planetary carrier. The third oil hole may be connected to the oil reservoir 6 of the planetary carrier and may correspond to the second oil hole. In this way, when the planetary carrier rotates above the lubricating oil level, the lubricating oil stored in the oil reservoir 6 of the planetary carrier will flow out through the third oil hole and the groove of the oil reservoir 6, and drip onto the planetary gear 4. It will then enter the bearing through the first oil hole 41 on the planetary gear 4 and the second oil hole on the outer ring of the bearing, thereby simultaneously lubricating the planetary gear 4 and the bearing, and further improving the lubrication effect on the planetary gear 4 and the bearing.

[0070] In a first alternative embodiment of the invention, such as Figure 5 As shown, the web 3 of the planetary carrier may also include a partition 33, which may be located in the oil reservoir 6 and may divide the oil reservoir 6 into a first oil reservoir and a second oil reservoir along the axial direction of the planetary carrier.

[0071] Here, the partition 33 can be perpendicularly connected to the first connecting plate 31 and the second connecting plate 32 of the web 3, respectively. This can further improve the rigidity of the web 3, thereby further improving the rigidity and stability of the planetary carrier.

[0072] In an optional embodiment, both the first connecting plate 31 and the second connecting plate 32 may be provided with a plurality of fourth oil holes 34, which may communicate with the second oil storage tank, and the plurality of fourth oil holes 34 may be evenly distributed along the radial direction of the planetary carrier.

[0073] Furthermore, the partition plate 33 can be provided with multiple fifth oil holes 35, which can be connected to the first oil reservoir and the second oil reservoir respectively. In this way, when the planetary carrier rotates above the lubricating oil level, the lubricating oil stored in the first oil reservoir of the planetary carrier can flow into the second oil reservoir through the fifth oil holes 35, and then flow out through the fourth oil hole 34, thus dripping onto the planet gears 4 and the sun gear. This can further improve the lubrication effect on the sun gear and the planet gears 4.

[0074] Here, the fifth oil hole 35 can be located near the radial outer end of the partition plate 33. This avoids affecting the oil storage effect of the first oil storage tank.

[0075] In a second optional embodiment of the present invention, a sixth oil hole may be provided on the first connecting plate 31 of the web 3, and a seventh oil hole may be provided on the second connecting plate 32 of the web 3. The sixth oil hole may penetrate the first connecting plate 31 radially along the planet carrier, and the seventh oil hole may penetrate the second connecting plate 32 radially along the planet carrier. In this way, when the planet carrier rotates below the lubricating oil level, the sixth and seventh oil holes can also play a certain oil storage function. As the planet carrier rotates, the lubricating oil in the sixth and seventh oil holes can drip onto the sun gear, thereby improving the lubrication effect on the sun gear.

[0076] In an optional embodiment, the two ends of the planetary gear 4 can be fitted with the first side plate 1 and the second side plate 2 respectively with clearance. This ensures that the planetary gear 4 and the planet carrier can rotate relative to each other, and allows lubricating oil to flow into the bearing through the gap between the planetary gear 4 and the first side plate 1 and the gap between the planetary gear 4 and the second side plate 2, thereby improving the lubrication effect on the bearing.

[0077] It should be noted that the aforementioned transmission device can be a speed reducer.
