Description

Technical Field

[0001] The utility model relates to the technical field of gearboxes, and more specifically, to a vertical gearbox. Background Art

[0002] Gearboxes, such as the wind power speed increasers applied in the field of gentle wind power generation, mainly adopt two layout forms: vertical and horizontal. Currently, the vertical speed increasers used in vertical wind turbines have at least the following problems:

[0003] 1) The oil seal of the vertical speed increaser is located at the bottom of the gearbox. Metal particles in the lubricating oil inside the box body are likely to deposit on the lip of the oil seal under the action of gravity, accelerating the wear of the lip and greatly shortening the service life of the oil seal;

[0004] 2) The oil level of the lubricating oil above the oil seal of the vertical speed increaser is relatively high, generating a relatively large pressure on the lip of the oil seal, further increasing the wear of the lip of the oil seal and shortening the service life of the oil seal;

[0005] 3) The oil change and maintenance period of the vertical speed increaser is generally 3 to 5 years. During this period, it is necessary to ensure the cleanliness of the lubricating oil inside the gearbox to avoid excessive contamination of the oil fluid, resulting in accelerated wear of transmission parts and seals and premature failure. Due to the short maintenance period and high oil change frequency, the usage cost is high. Summary of the Utility Model

[0006] The purpose of the utility model includes providing a vertical gearbox, which can extend the service life of the lip of the oil seal and reduce the operation cost.

[0007] The embodiments of the utility model can be implemented as follows:

[0008] In a first aspect, the utility model provides a vertical gearbox, comprising:

[0009] A box shell, a transmission assembly, a sealing assembly, and an oil guiding isolation baffle. The transmission assembly includes a high-speed output shaft, the high-speed output shaft is rotatably fitted with the bottom of the box shell, and the sealing assembly is installed between the box shell and the high-speed output shaft; the oil guiding isolation baffle is installed on the high-speed output shaft and is located on the side of the sealing assembly away from the bottom of the box shell.

[0010] In an optional embodiment, an assembly hole is provided at the bottom of the box shell, the high-speed output shaft is rotatably installed in the assembly hole, and the sealing assembly is located in the assembly hole; the outer contour of the orthographic projection of the assembly hole in a preset plane is located within the area enclosed by the outer contour of the orthographic projection of the oil guiding isolation baffle in the preset plane; the preset plane is perpendicular to the axis of the assembly hole.

[0011] Based on the above solution, the high-speed output shaft is inserted into the assembly hole, and the assembly hole is used to position the high-speed output shaft and the seal assembly, making assembly easy and tight. Furthermore, the orthographic projection of the assembly hole within the preset plane is located within the area enclosed by the orthographic projection of the oil-conducting isolation baffle within the preset plane. That is, the edges of the oil-conducting isolation baffle completely block the top of the assembly hole, increasing the probability that the lubricating oil will be blocked by the oil-conducting isolation baffle during its fall. Lubricating oil is less likely to enter the assembly hole directly from the top of the assembly hole, further reducing the amount of lubricating oil reaching the seal assembly, and reducing debris and other impurities that reach the seal assembly. This makes the seal assembly less susceptible to wear and failure, and extends its service life.

[0012] In an optional embodiment, the oil guide isolation baffle includes an annular mounting plate body and an annular oil guide plate body, the annular oil guide plate body is arranged on the outer periphery of the annular mounting plate body, the annular oil guide plate body is arranged at an angle to the annular mounting plate body, and the side of the annular oil guide plate body away from the annular mounting plate body is inclined toward the bottom of the box shell.

[0013] Based on the above scheme, when the annular oil guide plate body of the oil guide isolation baffle rotates, the lubricating oil is thrown from the four edges of the annular oil guide plate body to the bottom of the box shell under the action of centrifugal force. The lubricating oil can be deposited at the bottom of the box shell, which is conducive to recycling.

[0014] In an optional embodiment, the transmission assembly further includes a bearing and a retaining ring, the outer ring of the bearing is connected to the housing, the inner ring of the bearing is sleeved on the outside of the high-speed output shaft, the retaining ring is fixed to the high-speed output shaft, and the inner ring of the bearing and the retaining ring cooperate to clamp the oil guide isolation baffle.

[0015] Based on the above scheme, the oil guide isolation baffle is clamped by the bearing and the retaining ring, and the axial freedom of the oil guide isolation baffle on the high-speed output shaft is limited. The position of the oil guide isolation baffle is stable and reliable, and it is not easy to drop and contact the box shell to cause wear, nor is it easy to weaken the blocking effect on the lubricating oil due to the increase in height.

[0016] In an optional embodiment, an oil pool surrounding the high-speed output shaft is provided at the bottom of the housing, and a bottom wall of the oil pool is lower than the top of the sealing assembly.

[0017] Based on the above solution, the oil guide isolation baffle rotates together with the high-speed output shaft. The lubricating oil is thrown out from the edges of the oil guide isolation baffle under the action of centrifugal force and falls into the oil pool. The metal impurities carried by the lubricating oil also enter the oil pool and are deposited in the oil pool. The metal impurities are not easily stirred, which reduces the metal impurities that reach the location of the sealing assembly with the lubricating oil and reduces the wear of the sealing assembly.

[0018] In an optional embodiment, oil separators are provided in the oil pool.

[0019] Based on the above solution, when the lubricating oil enters the oil sump, its speed is reduced by the blocking of the oil separation ribs. The speed of the metal impurities in the lubricating oil is also reduced, and it is not easy for the metal impurities to move with the lubricating oil to the position where the sealing assembly is located, reducing the wear of the sealing assembly.

[0020] In an alternative embodiment, a magnet is provided in the oil sump.

[0021] Based on the above solution, the lubricating oil accumulates in the oil sump, and the metal impurities carried in the lubricating oil are also deposited in the oil sump. The metal impurities are adsorbed by the magnet, and it is not easy for the metal impurities to move with the lubricating oil, improving the cleanliness of the lubricating oil stirred to the upper part of the housing. When the lubricating oil falls, part of the lubricating oil enters the position where the sealing assembly is located. Since the lubricating oil has high cleanliness and few metal impurities, the speed of wear of the sealing assembly is small and the service life is extended.

[0022] In an alternative embodiment, a mounting seat is provided on the bottom wall of the oil sump. The mounting seat is provided with a mounting groove, and the magnet is arranged in the mounting groove.

[0023] Based on the above solution, the magnet is positioned by the mounting seat, and the position of the magnet is stable and reliable, not easy to shift under the agitation of the lubricating oil, and not easy to collide with other components such as the housing, improving the use safety. Moreover, the magnet is positioned at the bottom of the housing, which is beneficial to adsorb the metal impurities deposited in the oil sump. And, the mounting seat is provided with a mounting groove. After the metal impurities enter the mounting groove, their movement range is limited and they are easily adsorbed and fixed by the magnet.

[0024] In an alternative embodiment, the vertical gearbox further includes a filtering assembly, and the filtering assembly is integrated on the housing.

[0025] Based on the above solution, the lubricating oil is filtered by the filtering assembly integrated on the housing, and the cleanliness of the lubricating oil is high, and the replacement period is extended. At the same time, the filtering assembly is integrated on the housing, and the distance between them is small, reducing the pipeline length and even omitting some pipelines, reducing the leakage probability and reducing the cost.

[0026] In an alternative embodiment, the filtering assembly includes an oil pump, a coarse filtering unit and a fine filtering unit all connected to the housing. The inlet of the oil pump communicates with the outlet of the coarse filtering unit, the inlet of the coarse filtering unit communicates with the inside of the housing, the outlet of the oil pump communicates with the inlet of the fine filtering unit, and the outlet of the fine filtering unit communicates with the inside of the housing; the inlet of the coarse filtering unit is lower than the outlet of the fine filtering unit.

[0027] Based on the above solution, the lubricating oil is sucked from the bottom into the coarse filter unit for the first filtration, and then enters the fine filter unit for the second filtration. The lubricating oil after the second filtration has high cleanliness, returns to the housing from the upper part, lubricates the transmission components in the upper part, and falls under the action of gravity, deposits in the oil sump, and realizes recycling.

[0028] The beneficial effects of the vertical gearbox provided by the embodiment of the present utility model include:

[0029] To sum up, for the vertical gearbox provided by this embodiment, by installing an oil guiding isolation baffle above the sealing assembly, and the oil guiding isolation baffle rotates together with the high-speed output shaft. When the lubricating oil falls from above, it is blocked by the oil guiding isolation baffle. When the lubricating oil and the metal and other impurities it carries fall on the oil guiding isolation baffle, under the action of centrifugal force, they move from the center to the periphery and fall on the bottom of the housing. The probability of the lubricating oil entering the position where the sealing assembly is located is small, and the probability of metal and other impurities reaching the sealing assembly is small, reducing the wear amount caused by the contact between the sealing assembly and the metal impurities, and extending the service life of the sealing assembly. At the same time, the oil guiding isolation baffle drives the lubricating oil to rotate, making the area between the sealing assembly and the oil guiding isolation baffle have a relatively high fluid velocity, which can reduce the oil pressure at the position where the sealing assembly is located, reduce wear, and extend the service life of the sealing assembly.

[0044] In the description of the present utility model, it should be noted that if terms such as "upper", "lower", "inner", "outer", etc. are used to indicate the orientation or positional relationship, it is based on the orientation or positional relationship shown in the drawings, or the orientation or positional relationship in which the product of the present utility model is customarily placed during use. This is only for the convenience of describing the present utility model and simplifying the description, rather than indicating or implying that the device or component referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore should not be construed as a limitation to the present utility model.

[0045] In addition, if terms such as "first", "second", etc. are only used for distinguishing descriptions, they cannot be understood as indicating or implying relative importance.

[0046] It should be noted that, without conflict, the features in the embodiments of the present utility model can be combined with each other.

[0047] Please combine Figures 1-8 , in this embodiment, the vertical gearbox includes a housing 100, a transmission assembly 200, a sealing assembly 300, and an oil guiding and isolating baffle 400. The transmission assembly 200 includes a high-speed output shaft 210. The high-speed output shaft 210 is rotatably engaged with the bottom of the housing 100. The sealing assembly 300 is installed between the housing 100 and the high-speed output shaft 210. The oil guiding and isolating baffle 400 is installed on the high-speed output shaft 210 and is located on the side of the sealing assembly 300 away from the bottom of the housing 100.

[0048] As described above, the working mode of the vertical gearbox provided in this embodiment is as follows:

[0049] The high-speed output shaft 210 of the vertical gearbox can be connected to the input shaft of the generator device through a coupling. And the input shaft of the vertical gearbox can be connected to the blade shaft through a coupling. The blade body rotates under the action of wind force, inputs torque to the transmission assembly 200, and after being speed-regulated by the transmission assembly 200, it is output from the high-speed output shaft 210. The high-speed output shaft 210 drives the generator device to operate for wind power generation. That is to say, the high-speed output shaft 210 increases the torque input by the blade shaft and then outputs it to the generator device, and the rotational speed of the high-speed output shaft 210 is higher than that of the blade shaft. During the operation of the vertical gearbox, the high-speed output shaft 210 drives the oil guiding and isolating baffle 400 to rotate together. The lubricating oil liquid inside the housing 100 lubricates the components such as the transmission assembly 200 inside the housing 100, and the sealing assembly 300 seals the position between the high-speed output shaft 210 and the housing 100.

[0050] It should be understood that by installing the oil guiding isolation baffle 400 above the sealing assembly 300 and the oil guiding isolation baffle 400 rotating together with the high-speed output shaft 210, when the lubricating oil drops from above, it is blocked by the oil guiding isolation baffle 400. When the lubricating oil and impurities such as metal carried by it fall on the oil guiding isolation baffle 400, under the action of centrifugal force, they move from the center to the four peripheral edges and fall on the bottom of the housing 100. The probability of the lubricating oil entering the position where the sealing assembly 300 is located is small, and the probability of impurities such as metal reaching the sealing assembly 300 is small, reducing the wear amount caused by the contact between the sealing assembly 300 and the metal impurities and extending the service life of the sealing assembly 300. At the same time, the oil guiding isolation baffle 400 rotates with the lubricating oil, making the area between the sealing assembly 300 and the oil guiding isolation baffle 400 have a relatively high fluid velocity, which can reduce the oil pressure at the position where the sealing assembly 300 is located, reduce wear, and extend the service life of the sealing assembly 300.

[0051] The following details of the vertical gearbox of the embodiment of the present application will be described by way of example.

[0052] Please refer to Figures 1-4 , in this embodiment, the vertical gearbox includes a housing 100, a transmission assembly 200, a sealing assembly 300, an oil guiding isolation baffle 400, an oil separating rib 500, a mounting seat 600, a magnet 700 and a filtering assembly 800. The transmission assembly 200 is installed in the housing 100 and can increase the torque of the blade shaft and output it to the generator device. The sealing assembly 300 is installed in the housing 100 and can seal the area corresponding to the transmission assembly 200 in the housing 100. The oil guiding isolation baffle 400 is installed in the housing 100 and can reduce the lubricating oil entering the sealing assembly 300. The oil separating rib 500 and the mounting seat 600 are both installed at the bottom of the housing 100. The magnet 700 is installed on the mounting seat 600. The filtering assembly 800 is integrated into the housing 100 and can make the lubricating oil circulate and filter the lubricating oil.

[0053] In this embodiment, the housing 100 can be set as a split structure. For example, the housing 100 can include an upper shell and a lower shell, etc. The upper shell and the lower shell can be fixedly connected by structural parts such as bolts, which is convenient for the assembly of the housing 100 and other structures such as the transmission assembly 200. A positioning cylinder 110 is arranged at the middle position of the lower shell, and the cavity of the positioning cylinder 110 is an assembly hole 111. An oil sump 101 is formed at the bottom of the lower shell. The oil sump 101 is an annular pool and is arranged around the axis of the positioning cylinder 110. The bottom wall of the oil sump 101 is lower than the upper opening of the positioning cylinder 110.

[0054] Meanwhile, a plurality of oil separation ribs 500 and a plurality of mounting seats 600 are provided on the bottom wall of the oil sump 101. The oil separation ribs 500 can be plate-shaped or strip-shaped, and the plurality of oil separation ribs 500 are arranged radially around the axis of the positioning cylinder 110. The plurality of mounting seats 600 are arranged at intervals on the bottom wall of the oil sump, and each mounting seat 600 is provided with a mounting groove 610, and at least one magnet 700 is installed in each mounting groove 610. The structural design of the oil separation ribs 500 enables the lubricating oil to be blocked by the oil separation ribs 500 when moving in the oil sump 101 after entering the oil sump 101, the speed of the lubricating oil is reduced, the speed of the metal impurities in the lubricating oil is reduced, and the metal impurities are not easily moved to the position where the seal assembly 300 is located along with the lubricating oil, reducing the wear of the seal assembly 300. The lubricating oil accumulates in the oil sump 101, and the metal impurities carried in the lubricating oil are also deposited in the oil sump 101. The speed of the metal impurities is low, and the metal impurities are easily adsorbed by the magnets 700, and the metal impurities are not easily moved along with the lubricating oil, improving the cleanliness of the lubricating oil stirred to the upper part of the housing 100. When the lubricating oil falls, part of the lubricating oil enters the position where the seal assembly 300 is located. Since the lubricating oil has high cleanliness and few metal impurities, the speed of wear of the seal assembly 300 is small and the service life is extended.

[0055] Please refer to Figure 3 In this embodiment, optionally, the transmission assembly 200 includes a high-speed output shaft 210, a bearing 220, and a retaining ring 230. The high-speed output shaft 210 is inserted into the assembly hole 111, and the seal assembly 300 is disposed in the assembly hole 111 and located between the positioning cylinder 110 and the high-speed output shaft 210. The outer ring of the bearing 220 is fixed to the upper housing, the inner ring of the bearing 220 is sleeved outside the high-speed output shaft 210, and the high-speed output shaft 210 is positioned by the bearing 220 and rotates more flexibly relative to the housing 100. The oil guiding and isolating baffle 400 is installed on the high-speed output shaft 210 and clamped by the inner ring and the retaining ring 230. The oil guiding and isolating baffle 400 is located above the positioning cylinder 110, and the seal assembly 300 is located in the positioning cylinder 110, and the lubricating oil is not easily introduced into the seal assembly 300 from above the positioning cylinder 110.

[0056] It should be understood that the retaining ring 230 can be an elastic snap ring or the like.

[0057] Please refer to Figure 5Optionally, the oil-guiding isolation baffle 400 includes an annular mounting plate body 410 and an annular oil-guiding plate body 420, each of which is an integral structure. The annular oil-guiding plate body 420 is disposed on the outer periphery of the annular mounting plate body 410, and is disposed at an angle to the annular mounting plate body 410. The side of the annular oil-guiding plate body 420 away from the annular mounting plate body 410 is inclined toward the bottom of the housing 100. The annular mounting plate body 410 is sleeved onto the outside of the high-speed output shaft 210 and is clamped by the inner ring and the retaining ring 230. The annular mounting plate body 410 can be connected to the high-speed output shaft 210 via a structure such as an anti-rotation pin or a spline, thereby ensuring that the oil-guiding isolation baffle 400 can rotate with the high-speed output shaft 210. It should be understood that when the annular oil guide plate body 420 of the oil guide isolation baffle 400 rotates, the lubricating oil liquid is thrown from the four edges of the annular oil guide plate body 420 to the bottom of the box shell 100 under the action of centrifugal force, and the lubricating oil liquid can be deposited at the bottom of the box shell 100, which is conducive to recycling.

[0058] Optionally, the outer contour of the orthographic projection of the assembly hole 111 within a predetermined plane is located within the area enclosed by the outer contour of the orthographic projection of the oil-conducting isolation baffle 400 within the predetermined plane; the predetermined plane is perpendicular to the axis of the assembly hole 111. In this manner, the edges of the oil-conducting isolation baffle 400 completely block the top of the assembly hole 111, increasing the probability that the lubricating oil will be blocked by the oil-conducting isolation baffle 400 during its fall. This makes it less likely that the lubricating oil will enter the assembly hole 111 directly from the top of the assembly hole 111, further reducing the amount of lubricating oil reaching the seal assembly 300 and reducing the amount of debris and other impurities that reach the seal assembly 300. This makes the seal assembly 300 less susceptible to wear and failure, and extends its service life.

[0059] It should be understood that in order to further improve the oil blocking effect, the edges of the oil guide isolation baffle 400 can be extended from the outer periphery of the positioning cylinder 110, reducing the lubricating oil reaching the upper end surface of the positioning cylinder 110, and the lubricating oil is not easy to enter the assembly hole 111 along the upper end surface of the positioning cylinder 110, thereby moving to the sealing assembly 300.

[0060] Optionally, the upper end surface of the positioning cylinder 110 may be set as a conical surface, and the conical surface is the outer side of the positioning cylinder 110 , which can also reduce the lubricating oil liquid remaining on the upper end surface of the positioning cylinder 110 .

[0061] Please combine Figure 1 、 Figures 6-8In this embodiment, the filter assembly 800 optionally includes an oil pump 810, a coarse filter unit 820, and a fine filter unit 830, all of which are connected to the tank housing 100. The oil pump 810 is integrated outside the tank housing 100, the coarse filter unit 820 is provided inside the tank housing 100, and the fine filter unit 830 is integrated outside the tank housing 100. The inlet of the oil pump 810 is connected to the outlet of the coarse filter unit 820, the inlet of the coarse filter unit 820 is connected to the interior of the tank housing 100, the outlet of the oil pump 810 is connected to the inlet of the fine filter unit 830, and the outlet of the fine filter unit 830 is connected to the interior of the tank housing 100; the inlet of the coarse filter unit 820 is lower than the outlet of the fine filter unit 830. Lubricating oil is drawn from the bottom into coarse filter unit 820 for a first filtration step, and then into fine filter unit 830 for a second filtration step. The clean, filtered lubricating oil returns from the top of the housing 100 to lubricate the upper transmission components. It then falls under gravity and settles in the oil pool 101, allowing for recycling. Furthermore, the filter assembly 800 is integrated into the housing 100, minimizing the distance between them. This reduces piping lengths and can even eliminate some piping, minimizing leakage and lowering costs.

[0062] It should be noted that the sealing assembly 300 may be a skeleton oil seal or the like.

[0063] The vertical gearbox provided in this embodiment utilizes an oil-conducting isolation baffle 400 installed above the seal assembly 300 to prevent lubricating oil from reaching the seal assembly 300, reducing the amount of metal impurities that come into contact with the seal assembly 300 and making the seal assembly 300 less susceptible to wear and failure. Furthermore, the high-speed rotation of the oil-conducting isolation baffle 400 creates a higher fluid velocity above the seal assembly 300, reducing pressure on the seal assembly 300, improving its operating conditions, and extending its service life. Furthermore, the lubricating oil is deposited within the oil sump 101, where its flow rate is slowed by the oil-conducting rib 500. Metal impurities are easily attracted by the magnets 700 within the oil sump 101, further reducing the amount of metal impurities stirred into the seal assembly 300. The lubricating oil also circulates within and outside the housing 100 through the filter assembly 800, filtering impurities from the lubricating oil during circulation. This ensures high lubricating oil cleanliness, extends replacement cycles, and reduces operating costs.

[0064] The above is only a specific implementation method of the present invention, but the protection scope of the present invention is not limited to this. Any changes or replacements that can be easily thought of by any technician familiar with this technical field within the technical scope disclosed in the present invention should be included in the protection scope of the present invention.
