Technical Field

[0001] The utility model relates to the technical field of gearboxes, and in particular, to an anti-oil leakage structure for the output of a reducer of a converter tilting device and a converter tilting device. Background Art

[0002] The converter tilting device is mainly used to ensure that the furnace body in the converter steelmaking equipment can tilt smoothly and be accurately positioned, so as to complete a series of process operations such as charging molten iron, tapping steel, feeding materials, and repairing the furnace in the converter. The existing converter tilting device generally includes four primary reducers (each primary reducer is equipped with a motor), a secondary reducer, and a torsion bar balancing device. Among them, the motors of the four primary reducers start, brake, and run synchronously; the first gears on the output shafts of the four primary reducers mesh with the second gears on the input shaft of the secondary reducer, and the first gears on the four output shafts are evenly spaced along the circumferential direction of the second gear to cooperate with driving the second gear to rotate. The secondary reducer is suspended on the trunnion and is used to drive the converter to tilt and rotate.

[0003] The inventor has found through research that the secondary reducer of the converter tilting device in the related technology has at least the following disadvantages:

[0004] In the existing converter tilting device, the bearings on both sides of the secondary reducer adopt forced thin oil lubrication, and double-channel J-shaped oil seals are used at the gland of the secondary reducer to prevent oil leakage. They are installed back-to-back, one for dust prevention and the other for oil leakage prevention, but there is still a risk of oil leakage. The leaked oil flows everywhere, polluting the environment and wasting resources. Summary of the Utility Model

[0005] The purpose of the utility model includes providing an anti-oil leakage structure for the output of a reducer of a converter tilting device and a converter tilting device, which can recycle the leaked oil, the oil is not easy to flow everywhere and pollute the environment, and can also improve the resource utilization rate.

[0006] The embodiments of the utility model can be implemented as follows:

[0007] In a first aspect, the utility model provides an anti-oil leakage structure for the output of a reducer of a converter tilting device, including:

[0008] An output shaft, an oil seal assembly, a gland, an oil collecting cover, and an oil delivery pipe; the gland is sleeved outside the output shaft and the two are rotatably matched; the oil seal assembly is installed between the output shaft and the gland, the oil collecting cover is installed on the gland and covers the outside of the oil seal assembly, and an oil collecting cavity is defined between the oil collecting cover and the gland; one end of the oil delivery pipe is installed on the oil collecting cover and communicates with the oil collecting cavity, and the other end of the oil delivery pipe is used to be connected with the gearbox housing.

[0009] In an alternative embodiment, a first fixing hole is provided on the transparent cover, a second fixing hole is provided on the oil collecting cover, a fastener is inserted through the second fixing hole, and the fastener is fixed in the first fixing hole; the oil collecting cover and the transparent cover are fixedly connected through the fastener.

By screwing the fastener, the fixed fit between the fastener and the first fixing hole can be achieved, which is convenient for operation. Moreover, by screwing the fastener in the reverse direction, it can be disengaged from the first fixing hole without damaging the fastener, which is convenient for operation and has a low usage cost.

[0013] In an alternative embodiment, the oil collecting cover includes an outer ring and an oil baffle, the oil baffle is fixedly welded on the inner circumferential surface of the outer ring, and the outer ring and the oil baffle cooperate to define an oil collecting groove; the second fixing hole is provided on the outer ring, the outer ring is attached to the transparent cover, and the transparent cover closes the notch of the oil collecting groove.

[0014] Based on the above solution, the oil collecting cover is formed by connecting the outer ring and the oil baffle, which is convenient for processing and has a low manufacturing cost. Also, the outer ring and the oil baffle cooperate to form an oil collecting groove, and the transparent cover closes the notch of the oil collecting groove so that the oil collecting groove forms an oil collecting cavity, without the need for additional processing of the transparent cover, reducing the processing difficulty of the transparent cover. The leaked lubricating oil enters the oil collecting groove and can flow downward along the oil baffle under the action of gravity, and the oil accumulates at the bottom of the oil collecting groove, which is conducive to recovery.

[0015] In an alternative embodiment, a sealing ring is provided between the outer ring and the transparent cover.

[0016] Based on the above solution, the sealing ring can increase the sealing performance between the outer ring and the transparent cover. When the oil leaks from the oil seal assembly, the oil enters the oil collecting groove and is located at the contact position between the transparent cover and the outer ring, and the oil is not likely to leak from the contact position between the transparent cover and the outer ring, making it safe and reliable to use.

[0017] In an alternative embodiment, an oil collecting groove is provided on the inner circumferential surface of the outer ring, and the oil collecting groove is located below the outer ring.

[0023] In an alternative embodiment, the anti-oil leakage structure of the output of the converter tilting device reducer further includes an oil slinger and a shaft end baffle. The oil slinger is sleeved outside the output shaft, and the oil seal assembly is arranged between the oil slinger and the through cover; the shaft end baffle is installed on the end face of the output shaft, and the shaft end baffle is used to abut against the oil slinger to limit the oil slinger from disengaging from the output shaft.

[0024] Based on the above solution, by providing the oil slinger and the shaft end baffle, when the lubricating oil reaches the oil slinger, the oil slinger rotates with the output shaft, which can sling the lubricating oil to the bearing, thereby improving the lubrication effect of the bearing and reducing the amount of lubricating oil reaching the position of the oil seal assembly, reducing the probability of lubricating oil leakage. At the same time, the shaft end baffle can not only limit the directly axially thrown out of the leaked lubricating oil along the output shaft, but also limit the position of the oil slinger, improving the reliability of the combination of the oil slinger and the output shaft.

[0025] In a second aspect, the present invention provides a converter tilting device, including the anti-oil leakage structure of the output of the converter tilting device reducer according to any one of the foregoing embodiments.

[0026] The beneficial effects of the anti-oil leakage structure of the output of the converter tilting device reducer and the converter tilting device provided by the embodiments of the present invention include:

[0027] In summary, for the anti-oil leakage structure at the output of the converter tilting device reducer provided in this embodiment, by adding an oil collecting cover outside the gland, the oil collecting cover can cover the oil seal assembly. During the operation of the gearbox, when the lubricating oil reaches the position of the oil seal assembly, most of the lubricating oil falls to the lower part of the gearbox housing under the block of the oil seal assembly, leaves the gearbox housing and participates in lubrication again after purification. There may be a small part of the lubricating oil leaking from the oil seal assembly. This part of the lubricating oil crosses the oil seal assembly and reaches the outside of the oil seal assembly. At this time, blocked by the oil collecting cover, the leaked lubricating oil enters the oil collecting cavity formed by the cooperation of the oil collecting cover and the gland. The lubricating oil is not easy to flow around and is not easy to pollute the environment. At the same time, an oil delivery pipe is installed on the oil collecting cover, and the end of the oil delivery pipe is connected to the gearbox housing. The lubricating oil in the oil collecting cover can flow back to the gearbox housing through the oil delivery pipe in time, which not only reduces the probability of the lubricating oil in the oil collecting cavity leaking again, but also improves the utilization rate of the lubricating oil, and the operation cost is low.

Detailed implementation mode

[0036] In the prior art, an oil seal is provided at the shaft end of the secondary speed reducer of the converter tilting device, which can seal the shaft end position and reduce the probability of lubricating oil leakage. However, due to various factors such as working conditions, assembly quality, and manufacturing errors, during the operation of the gearbox, a small amount of lubricating oil will also leak from the oil seal at the shaft end. The leaked lubricating oil flows everywhere and pollutes the environment.

[0037] In view of this, the designer provides an anti - oil - leakage structure for the output of the converter tilting device speed reducer. By collecting the leaked lubricating oil and returning it to the gearbox housing 001, it not only prevents the lubricating oil from flowing everywhere and polluting the environment, but also improves the utilization rate of the lubricating oil.

[0038] To make the objectives, technical solutions, and advantages of the embodiments of the present utility model clearer, the technical solutions in the embodiments of the present utility model will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present utility model.

This is only for the convenience of describing the present utility model and simplifying the description, rather than indicating or implying that the indicated device or component must have a specific orientation, be constructed and operated in a specific orientation. Therefore, it should not be construed as a limitation to the present utility model.

[0042] 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.

[0043] It should be noted that, without conflict, the features in the embodiments of the present utility model can be combined with each other.

[0044] Please combine Figures 1 - 5 , in this embodiment, the anti-oil leakage structure of the output of the converter tilting device reducer includes an output shaft 100, an oil seal assembly 200, a through cover 300, an oil collecting cover 400, and an oil delivery pipe 500. The through cover 300 is sleeved outside the output shaft 100 and the two are rotatably matched. The oil seal assembly 200 is installed between the output shaft 100 and the through cover 300. The oil collecting cover 400 is installed on the through cover 300 and covers the outside of the oil seal assembly 200. An oil collecting cavity is defined between the oil collecting cover 400 and the through cover 300. One end of the oil delivery pipe 500 is installed on the oil collecting cover 400 and communicates with the oil collecting cavity, and the other end of the oil delivery pipe 500 is used to connect with the gearbox housing 001.

[0045] As described above, the usage method of the anti-oil leakage structure of the output of the converter tilting device reducer provided in this embodiment is as follows:

[0046] When the lubricating oil enters the shaft end position of the output shaft 100, the lubricating oil is blocked by the oil seal assembly 200, and it is not easy for the lubricating oil to leak from the shaft end of the output shaft 100. However, due to various factors, there may be a situation where part of the lubricating oil leaks from the oil seal assembly 200. In this case, when the lubricating oil leaks from the oil seal assembly 200 to the outside of the output shaft 100, the leaked lubricating oil is blocked by the oil collecting cover 400 outside the through cover 300, and the leaked lubricating oil enters the oil collecting cavity formed by the cooperation of the oil collecting cover 400 and the through cover 300. The lubricating oil is not easy to flow around and is not easy to pollute the environment. At the same time, the oil delivery pipe 500 is installed on the oil collecting cover 400, and the end of the oil delivery pipe 500 is connected to the gearbox housing 001. The lubricating oil in the oil collecting cover 400 can flow back to the gearbox housing 001 in time through the oil delivery pipe 500, which not only reduces the probability of the lubricating oil in the oil collecting cavity leaking again, but also improves the utilization rate of the lubricating oil and has a low operating cost.

[0047] The following embodiments illustrate the detailed structure of the output oil leakage prevention structure of the reducer of the converter tilting device of the present application by way of examples.

[0048] In this embodiment, optionally, a first fixing hole is provided on the transparent cover 300, and a second fixing hole 401 is provided on the oil collecting cover 400. A fastener 900 is passed through the second fixing hole 401 and fixed to the first fixing hole; the oil collecting cover 400 and the transparent cover 300 are fixedly connected via the fastener 900. Connecting the oil collecting cover 400 and the transparent cover 300 via the fastener 900 is simple and easy to operate. The oil collecting cover 400 can also be removed from the transparent cover 300 by removing the fastener 900, facilitating replacement or maintenance.

[0049] It should be noted that the first fixing holes are threaded holes. Furthermore, the number of first fixing holes can be multiple, and this is not specifically limited in this embodiment. The multiple first fixing holes are evenly spaced and arranged around the circumference of the transparent cover 300. Correspondingly, the number of second fixing holes 401 can be multiple, and the number of second fixing holes 401 can be equal to the number of first fixing holes.

[0050] Please combine Figure 5 It should be understood that by inserting the fastener 900 into the second fixing hole 401 and threading the fastener 900 into the corresponding first fixing hole, the fastener 900 and the first fixing hole can be fixedly engaged by simply screwing the fastener 900, which is convenient to operate. Furthermore, the fastener 900 can be removed from the first fixing hole by screwing it in the opposite direction without destroying the fastener 900, which is convenient to operate and low in cost.

[0051] Please combine Figure 5 In this embodiment, the oil collecting cover 400 optionally includes an outer ring 410 and an oil baffle 420. The oil baffle 420 is welded to the inner circumference of the outer ring 410. The outer ring 410 and the oil baffle 420 cooperate to define an oil collecting trough. A second fixing hole 401 is provided on the outer ring 410. The outer ring 410 engages with the transparent cover 300, which seals the notch of the oil collecting trough. The oil collecting cover 400 is manufactured by connecting the outer ring 410 and the oil baffle 420, making it easy to manufacture and low in cost. The outer ring 410 and the oil baffle 420 cooperate to form the oil collecting trough. The transparent cover 300 seals the notch of the oil collecting trough, forming an oil collecting chamber. This eliminates the need for additional machining of the transparent cover 300, reducing the difficulty of manufacturing the transparent cover 300. Leaked lubricating oil enters the oil collecting trough and flows downward under the action of gravity along the oil baffle 420. The oil accumulates at the bottom of the oil collecting trough, facilitating recovery.

[0052] It should be understood that the outer ring 410 may be a circular ring, and the oil baffle plate 420 may be a circular ring-shaped plate.

[0053] Please combine Figures 3 - 4Optionally, a sealing ring 600 is provided between the outer ring 410 and the transparent cover 300. The sealing ring 600 can improve the sealing between the outer ring 410 and the transparent cover 300. When oil leaks from the oil seal assembly 200, the oil enters the oil collecting tank and is located at the contact position between the transparent cover 300 and the outer ring 410. The oil is not likely to leak from the contact position between the transparent cover 300 and the outer ring 410, and the use is safe and reliable.

[0054] To facilitate installation of the sealing ring 600, an annular groove is provided on the outer ring 410, corresponding to the side of the transparent cover 300. The sealing ring 600 is positioned within the annular groove, where it is retained and positioned, ensuring a stable and reliable position. Furthermore, all second fixing holes 401 are located outside the annular groove, thus preventing lubricating oil from leaking from the second fixing holes 401.

[0055] In other embodiments, the inner circumferential surface of the outer ring 410 is optionally provided with an oil collecting groove 402, which is located below the outer ring 410. The provision of the oil collecting groove 402 can increase the oil collection capacity, and the oil is collected in the oil collecting groove 402, making it easier to input the oil into the gearbox housing 001 via the oil delivery pipe 500.

[0056] Optionally, an oil outlet hole is provided on the outer ring 410, which communicates with the bottom of the oil collecting groove 402. A pipe connector 430 is mounted on the outer ring 410, connecting to the oil outlet hole. One end of the oil delivery pipe 500 is connected to the pipe connector 430. The oil outlet hole is provided on the outer ring 410, and can be located below the outer ring 410. This allows the lubricating oil to flow from the oil outlet hole into the oil delivery pipe 500 under the action of gravity, and then flow back from the oil delivery pipe 500 into the gearbox housing 001.

[0057] It should be understood that the oil delivery pipe 500 can be connected to the pipe joint 430 by a snap fastener, or the oil delivery pipe 500 and the pipe joint 430 can be fixed by screws, etc.

[0058] In this embodiment, the oil delivery pipe 500 can optionally be configured as a shaped hose. The shape of the oil delivery pipe 500 can be adjusted as needed, which not only facilitates avoiding external structural components during installation, but also allows the oil delivery pipe 500 to be adjusted to a curved shape, that is, the oil delivery pipe 500 has at least one curved section, thereby reducing the probability of oil flowing back from the oil delivery pipe 500 into the oil collecting chamber.

[0059] In this embodiment, optionally, the output oil leakage prevention structure of the reducer of the converter tilting device also includes an oil flinger 700 and a shaft end baffle 800. The oil flinger 700 is sleeved on the outside of the output shaft 100, and the oil seal assembly 200 is arranged between the oil flinger 700 and the transparent cover 300; the shaft end baffle 800 is installed on the end face of the output shaft 100, and the shaft end baffle 800 is used to abut against the oil flinger 700 to limit the oil flinger 700 from separating from the output shaft 100.

[0060] It should be understood that by providing the oil slinger ring 700 and the shaft end baffle 800, when the lubricating oil reaches the oil slinger ring 700, the oil slinger ring 700 rotates together with the output shaft 100, and can sling the lubricating oil to the bearing 003, thereby improving the lubrication effect of the bearing 003 and reducing the amount of lubricating oil reaching the position where the oil seal assembly 200 is located, and reducing the probability of lubricating oil leakage. At the same time, the shaft end baffle 800 can not only limit the directly axial ejection of the leaked lubricating oil along the output shaft 100, but also limit the position of the oil slinger ring 700, improving the reliability of the combination of the oil slinger ring 700 and the output shaft 100.

[0061] The anti-oil leakage structure at the output of the converter tilting device reducer provided in this embodiment, through the cooperation of the oil collecting cover 400 and the oil delivery pipe 500, can collect the leaked lubricating oil through the oil collecting cover 400 and return it to the gearbox housing 001 through the oil delivery pipe 500, enabling the lubricating oil to be reused and improving the resource utilization rate.

[0062] This embodiment also provides a converter tilting device, including a gearbox housing 001, a bearing bush 002, a bearing 003, and an anti-oil leakage structure at the output of the converter tilting device reducer. The bearing bush 002 is fixed to the gearbox housing 001, the outer ring of the bearing 003 is fixed within the bearing bush 002, the inner ring of the bearing 003 is sleeved outside the output shaft 100, and the output shaft 100 is rotatably coupled to the gearbox housing 001 through the bearing 003.

[0063] As described above, the above are only specific embodiments of the present utility model, but the protection scope of the present utility model is not limited thereto. Any changes or substitutions that can be easily thought of by those skilled in the art within the technical scope disclosed by the present utility model should be covered within the protection scope of the present utility model.
