Description

Technical Field

[0001] This utility model relates to the field of oil filter technology, and more specifically to a gearbox oil filter. Background Technology

[0002] With the rapid development of the wind power industry, the number of wind turbine units is constantly increasing, which puts forward higher requirements for equipment maintenance. As one of the core components of wind turbines, the normal operation of the wind turbine gearbox is directly related to the power generation efficiency and economic benefits of the entire wind farm. The gearbox oil filter element can prevent tiny particles from entering the system through effective filtration, thereby extending the service life of the gearbox and its internal components and reducing maintenance costs.

[0003] Existing gearbox oil filters are affected by low temperatures, causing the lubricating oil inside to become viscous and its fluidity to decrease significantly. This change directly affects the filtration efficiency, preventing the filter from performing effective filtration at a high rate. This not only reduces the operating efficiency of the equipment but may also lead to premature wear or damage to mechanical parts due to insufficient lubrication.

[0004] In addition, there is another inconvenience in the design of the gearbox oil filter elements commonly available on the market - the process of replacing the filter cotton is very complicated and time-consuming. Whenever a new filter material needs to be replaced, the user often has to completely disassemble the entire device from the system to complete the operation. This step not only increases maintenance costs but also prolongs downtime, which is particularly disadvantageous for companies that pursue efficient production and continuous operation.

[0005] Therefore, in order to solve the above problems, this application provides a gearbox oil filter element. Utility Model Content

[0006] In order to overcome the above-mentioned defects of the prior art, the present invention provides a gearbox oil filter element to solve the problems existing in the background art.

[0007] This utility model provides the following technical solution: a gearbox oil filter element, including a housing assembly and a check assembly installed below the housing assembly, a filter assembly installed below the check assembly, a pressure relief assembly installed below the filter assembly, and a heating assembly installed below the housing assembly;

[0008] Preferably, the housing assembly includes a filter element housing, a sealing ring, an inlet tray, and inlet holes, wherein the sealing ring is fixedly snapped onto the top of the filter element housing, the inlet tray is fixedly installed on the sealing ring, and a row of circumferentially distributed inlet holes is provided on the inlet tray.

[0009] Preferably, the check valve assembly includes a check valve, a limiter, a limit groove, and a fixing head. The limiter is fixedly installed below the inlet tray, and the check valve is disposed between the inlet tray and the limiter. The limiter has a limit at the engagement point with the check valve, and the limiter engages with the fixing head below the check valve. The check valve is made of rubber. When subjected to force from above, the edge of the check valve will bend downward, allowing the inlet hole to communicate with the inner cavity of the filter element housing. At this time, lubricating oil enters the cavity formed by the check valve and the inlet tray through the inlet hole. Since the check valve is made of rubber, it deforms under the pressure of the lubricating oil, and the lubricating oil enters the inner cavity of the filter element housing from the gap created by the deformation of the check valve.

[0010] Preferably, the filter assembly includes a filter cartridge, filter holes, filter cotton, a fixing frame, a fixing ring, a lower end cap, and a handle. The filter cartridge is fixedly installed below the limiter. The filter cartridge has evenly distributed filter holes on its side wall. The filter cotton is movably sleeved on the filter cartridge. The fixing frame is attached to the filter cotton. The fixing ring is fixedly connected to the lower part of the fixing frame. The fixing ring is rotatably sleeved on the lower end cap. The lower end cap is threaded onto the bottom of the filter element housing. The handle is fixedly installed at the bottom of the lower end cap. At this time, under the action of the filter cotton, the lubricating oil is filtered and enters the inner cavity of the filter cartridge through the filter holes, and then discharged through the through hole at the top, thus completing the filtration of the lubricating oil. In addition, the lower end cap can be rotated so that the lower end cap is no longer stuck to the filter element housing. At this time, pulling the handle outward will cause the filter cotton and the fixing frame to slide out along the contact area with the filter cartridge, thereby facilitating the replacement of the filter cotton.

[0011] Preferably, the pressure relief assembly includes a pressure relief chamber, a spring, a valve body, and a retaining groove. The pressure relief chamber is fixedly installed at the bottom of the filter cartridge's inner cavity, and the bottom of the pressure relief chamber is connected to the inner cavity of the filter element housing. The bottom of the valve body has a retaining groove, and the valve body is movably engaged in the pressure relief chamber through the retaining groove. The spring is disposed between the pressure relief chamber and the valve body. When the pressure in the inner cavity of the filter element housing is too high, the valve body moves towards the end closer to the spring, allowing lubricating oil to enter the filter cartridge through the pressure relief chamber.

[0012] Preferably, the heating assembly includes a rotary motor, a first gear, a second gear, a rotating rod, a rotating blade, and a heating ring. The rotary motor is fixedly installed at the bottom of the lower end cover. The drive shaft of the rotary motor passes through the lower end cover and is fixedly sleeved on the first gear. The first gear meshes with the second gear. The rotating blade is fixedly sleeved above the second gear. One end of the rotating rod is rotatably engaged with the lower end cover, and the other end is fixedly sleeved on the second gear. The heating ring is fixedly sleeved on the inner wall of the bottom of the filter element housing. At this time, the heating ring heats the lubricating oil in the filter element housing by connecting to a power source. Simultaneously, the drive shaft of the rotary motor drives the first gear. Under the meshing action between the first gear and the second gear, the second gear and the rotating blade are driven to rotate along the rotating rod, stirring the lubricating oil in the filter element housing, thereby increasing the heating rate of the lubricating oil.

[0013] The technical effects and advantages of this utility model are as follows:

[0014] When the lubricating oil has poor fluidity due to temperature issues in winter, the heating ring connects to the power supply to heat the lubricating oil inside the filter element housing. At the same time, the rotating motor drive shaft drives the first gear, and through meshing, it drives the rotating blade to rotate, stirring the lubricating oil and thus increasing the heating rate of the lubricating oil. After long-term use, the lower end cover can be rotated to remove the jamming between the lower end cover and the filter element housing. At this time, pulling the handle outward will allow the filter cotton and the fixing bracket to slide out along the contact area with the filter cartridge, thus facilitating the replacement of the filter cotton.

[0020] The technical solution of this utility model will be clearly and completely described below with reference to the accompanying drawings. In addition, the forms of the various structures described in the following embodiments are merely illustrative. The gearbox oil filter element involved in this utility model is not limited to the structures described in the following embodiments. All other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this utility model.

[0021] Reference Figure 1 and Figure 2 The present invention provides a gearbox oil filter element, including a housing assembly 1 and a check assembly 2 installed below the housing assembly 1. A filter assembly 3 is installed below the check assembly 2, a pressure relief assembly 4 is installed below the filter assembly 3, and a heating assembly 5 is installed below the housing assembly 1.

[0022] Reference Figure 1 and Figure 2 The outer casing assembly 1 includes a filter housing 101, a sealing ring 102, an inlet tray 103, and an inlet hole 104. The sealing ring 102 is fixedly snapped onto the top of the filter housing 101, and the inlet tray 103 is fixedly installed on the sealing ring 102. A row of inlet holes 104 distributed in a circular pattern are provided on the inlet tray 103.

[0023] Reference Figure 2 and Figure 3 The check valve assembly 2 includes a check valve 201, a limiter 202, a limit groove 203, and a fixing head 204. The limiter 202 is fixedly installed below the inlet plate 103. The check valve 201 is located between the inlet plate 103 and the limiter 202. The limiter 202 has a limiter 202 at the engagement point with the check valve 201. The limiter 202 is engaged with the fixing head 204 below the check valve 201. The check valve 201 is made of rubber. When subjected to force from above, the edge of the check valve 201 will bend downward so that the inlet hole 104 communicates with the inner cavity of the filter element housing 101. At this time, lubricating oil enters the cavity formed by the check valve 201 and the inlet plate 103 through the inlet hole 104. Since the check valve 201 is made of rubber, it deforms under the pressure of the lubricating oil. The lubricating oil enters the inner cavity of the filter element housing 101 from the gap caused by the deformation of the check valve 201.

[0024] Reference Figure 1 and Figure 2The filter assembly 3 includes a filter cartridge 301, filter holes 302, filter cotton 303, a fixing frame 304, a fixing ring 305, a lower end cover 306, and a handle 307. The filter cartridge 301 is fixedly installed below the limiter 202. The filter cartridge 301 has evenly distributed filter holes 302 on its side wall. The filter cotton 303 is movably sleeved on the filter cartridge 301. The fixing frame 304 is attached to the filter cotton 303. The fixing ring 305 is fixedly connected to the lower part of the fixing frame 304. The fixing ring 305 is rotatably sleeved on the lower end cover 306. The lower end cover 306 is threaded onto the filter element. At the bottom of the housing 101, the handle 307 is fixedly installed at the bottom of the lower end cover 306. At this time, under the action of the filter cotton 303, the lubricating oil is filtered and enters the inner cavity of the filter cartridge 301 through the filter hole 302, and then discharged through the upper through hole, thus completing the filtration of the lubricating oil. In addition, the lower end cover 306 can be rotated so that the lower end cover 306 is no longer stuck to the filter element housing 101. At this time, pulling the handle 307 outward will cause the filter cotton 303 and the fixing bracket 304 to slide out along the contact point with the filter cartridge 301, thereby facilitating the operation of replacing the filter cotton 303.

[0025] Reference Figure 1 and Figure 2 The pressure relief assembly 4 includes a pressure relief chamber 401, a spring 402, a valve body 403, and a slot 404. The pressure relief chamber 401 is fixedly installed at the bottom of the inner cavity of the filter cartridge 301, and the bottom of the pressure relief chamber 401 is connected to the inner cavity of the filter element housing 101. The bottom of the valve body 403 is provided with a slot 404, and the valve body 403 is movably engaged in the pressure relief chamber 401 through the slot 404. The spring 402 is disposed between the pressure relief chamber 401 and the valve body 403. When the pressure in the inner cavity of the filter element housing 101 is too high, the valve body 403 moves towards the end closer to the spring 402, so that the lubricating oil enters the filter cartridge 301 through the pressure relief chamber 401.

[0026] Reference Figure 2 and Figure 4 The heating assembly 5 includes a rotary motor 501, a first gear 502, a second gear 503, a rotating rod 504, a rotating blade 505, and a heating ring 506. The rotary motor 501 is fixedly installed at the bottom of the lower end cover 306. The drive shaft of the rotary motor 501 passes through the lower end cover 306 and is fixedly sleeved onto the first gear 502. The first gear 502 meshes with the second gear 503. The rotating blade 505 is fixedly sleeved above the second gear 503. One end of the rotating rod 504 is rotatably sleeved onto the lower end cover 306, and the other end is fixedly sleeved onto... Connecting to the second gear 503, the heating ring 506 is fixedly sleeved on the inner wall of the bottom of the filter element housing 101. At this time, the heating ring 506 heats the lubricating oil in the filter element housing 101 by connecting to the power supply. At the same time, the drive shaft of the rotating motor 501 drives the first gear 502. Under the meshing action between the first gear 502 and the second gear 503, the second gear 503 and the rotating blade 505 are driven to rotate along the rotating rod 504, which stirs the lubricating oil in the filter element housing 101, thereby increasing the heating rate of the lubricating oil.

[0027] The working principle of this utility model is as follows: When the device is running, lubricating oil enters the cavity formed by the check valve 201 and the inlet plate 103 through the inlet hole 104. Since the check valve 201 is made of rubber, it deforms under the pressure of the lubricating oil. The lubricating oil enters the inner cavity of the filter element housing 101 through the gap created by the deformation of the check valve 201. Under the action of the filter cotton 303, the lubricating oil is filtered and enters the inner cavity of the filter cartridge 301 through the filter hole 302, and then exits through the through hole at the top, completing the filtration of the lubricating oil. When the pressure in the inner cavity of the filter element housing 101 is too high, the valve body 403 moves towards the end closer to the spring 402, allowing the lubricating oil to enter the filter cartridge 301 through the pressure relief chamber 401. In winter, the temperature of the lubricating oil causes flow problems. When the mobility is poor, the heating ring 506 connects to the power supply to heat the lubricating oil in the filter element housing 101. At the same time, the drive shaft of the rotating motor 501 drives the first gear 502. Under the meshing action between the first gear 502 and the second gear 503, the second gear 503 and the rotating blade 505 are driven to rotate along the rotating rod 504 to stir the lubricating oil in the filter element housing 101, thereby increasing the heating rate of the lubricating oil. After long-term use, the lower end cover 306 can be rotated to make the lower end cover 306 no longer stuck to the filter element housing 101. At this time, the handle 307 is pulled outward to make the filter cotton 303 and the fixing frame 304 slide out along the contact point with the filter cylinder 301, thereby facilitating the replacement of the filter cotton 303.
