Description

Technical Field

[0001] This utility model relates to the field of transmission component manufacturing, and in particular to an integrated cleaning and drying device for large gears. Background Technology

[0002] As a critical transmission component, the surface cleanliness of gears directly affects their assembly accuracy, lubrication effect, and service life. Especially in high-precision transmission systems, gears often retain contaminants such as cutting fluid, metal shavings, oil, and tiny particles after finishing, which must be removed through a cleaning process to avoid affecting the stability of the equipment's transmission.

[0003] Gears are generally classified by their pitch circle diameter into micro gears (less than 20mm), small gears (20-100mm), medium gears (100-500mm), large gears (500-1000mm), and extra-large gears (greater than 1000mm). Currently, several mature automated cleaning equipment options exist for cleaning small and medium-sized gears (e.g., those with a pitch circle diameter less than 500mm). These devices typically employ a multi-station cleaning structure, simultaneously performing processes such as spraying, ultrasonic cleaning, rinsing, and hot air drying on multiple gears. They offer advantages such as high cleaning efficiency, ease of operation, energy saving, and environmental friendliness.

[0004] For large and extra-large gears, their size and weight make them unsuitable for traditional cleaning equipment, resulting in existing cleaning operations still primarily relying on manual methods. For example, operators use high-pressure water guns or brushes to rinse each gear individually, supplementing with wiping with cotton cloths and natural air drying or localized heating for drying. This method is not only labor-intensive and inefficient, but also produces inconsistent cleaning quality, easily causing secondary contamination or damaging the gear surface, affecting subsequent assembly and operational performance.

[0005] Based on this, this case proposes an integrated cleaning and drying equipment for large gears. Utility Model Content

[0006] The purpose of this invention is to provide an integrated cleaning and drying device for large gears, so as to achieve the brushing and drying of large gears.

[0007] To achieve the above objectives, the technical solution of this utility model is as follows:

[0008] An integrated cleaning and drying device for large gears includes a base and a cleaning cylinder, with the cleaning cylinder fixed to the base. The bottom center of the cleaning cylinder has a mounting hole, through which a lifting cylinder is mounted via a bearing. The piston end of the lifting cylinder is located inside the cleaning cylinder, and a gear fixing shaft is mounted at its top. The gear fixing shaft is used to fix the gear to be cleaned. The cylinder body end of the lifting cylinder protrudes downwards from the bottom of the cleaning cylinder and is rotatably connected to the base. A rotating unit is mounted on the base, its rotating end being drively connected to the cylinder body end of the lifting cylinder to drive the lifting cylinder to rotate. The cleaning cylinder is divided into an upper drying zone and a lower cleaning zone. The drying zone has a circumferentially arranged hot air module for drying the cleaned gears, and the cleaning zone has a circumferentially arranged brush module for brushing the tooth grooves of the gears to be cleaned. The cleaning zone also includes a water inlet module and a drainage module.

[0009] Furthermore, the rotating unit adopts a servo motor, and a synchronous pulley is fixed to the shaft end of the servo motor. The lifting cylinder includes a fixed wheel shaft, the upper end of which is fixed to the bottom end of the cylinder body of the lifting cylinder, and the lower end of which is rotatably connected to the base through a bearing. A synchronous pulley is fixed on the fixed wheel shaft, and the synchronous pulley and the synchronous pulley are connected by a synchronous belt drive.

[0010] Furthermore, the bottom surface of the cleaning cylinder is provided with several mounting holes 2 around the mounting hole 1. The mounting holes 2 are located between the mounting hole 1 and the cylinder brush module. A lifting cylinder 2 is fixed in the mounting hole 2. The piston end of the lifting cylinder 2 is located inside the cleaning cylinder and the end is fixed with a universal ball joint for supporting the gear to be cleaned. The cylinder body end of the lifting cylinder 2 protrudes downward from the bottom of the cleaning cylinder and is fixed to the base.

[0011] Furthermore, the gear fixing shaft is connected to the gear to be cleaned via a keyway, and a limiting support plate with an outer diameter larger than the gear fixing shaft is provided between the gear fixing shaft and the piston end of the lifting cylinder.

[0012] Furthermore, the cylindrical brush module includes a vertically arranged cylindrical brush body, which includes a central shaft, a sleeve, and bristles. The central shaft is located inside the sleeve and is connected to the sleeve via a bearing. The bristles are densely distributed on the outer wall of the sleeve. Both the upper and lower ends of the central shaft protrude from the sleeve and are connected to the cleaning cylinder.

[0013] Furthermore, the cylindrical brush module includes a first sliding groove located above the cylindrical brush body, a second sliding groove located below the cylindrical brush body, a spring push rod, and an electric push rod. The upper end of the central shaft is provided with a slider 1 that is slidably connected to the first sliding groove, and the lower end of the central shaft is provided with a slider 2 that is slidably connected to the second sliding groove. The sliding direction of slider 1 and slider 2 is set along the radial direction of the cleaning cylinder.

[0014] The elastic push rod is fixed to the bottom surface of the cleaning cylinder and located between the second slider and the wall of the cleaning cylinder. Its telescopic end is fixed to the second slider and is used to push the second slider to slide towards the lifting cylinder.

[0015] The electric push rod is fixed to the bottom surface of the cleaning cylinder and located between the second slider and the first lifting cylinder. The electric push rod and the spring push rod are located in the same radial direction. The telescopic end of the electric push rod can contact the second slider and is used to push the second slider to move towards the wall of the cleaning cylinder.

[0016] Furthermore, the elastic push rod includes a rod body, a spring, and a rod sleeve with one end open. One end of the rod body is located inside the rod sleeve and a limiting seat is integrally formed at that end. The other end of the rod body protrudes from the open end of the rod sleeve. The spring is disposed between the closed end of the rod sleeve and the limiting seat of the rod body for pushing the rod body out of the rod sleeve.

[0017] Furthermore, it includes a truss located above the cleaning cylinder, on which a cylinder cover lifting mechanism is installed. The lifting end of the cylinder cover lifting mechanism is provided with a cylinder cover that matches the cleaning cylinder. Several air nozzles are arranged on the cylinder cover, and the air jet direction of the air nozzles is inclined downward and diffuses from the center to the surrounding area.

[0018] The cylinder cover is provided with an air supply channel that communicates with the jet nozzle.

[0019] The advantages of this utility model are:

[0020] 1. This solution is suitable for cleaning, brushing, and drying large single gears, replacing manual cleaning and effectively improving cleaning efficiency and quality. Further improvements can be made, such as optimizing the central gear fixing shaft, rotating unit, and lifting unit to support automated cleaning of ultra-large gears. 2. The solution includes a cylindrical brush module to mimic manual brushing of gear tooth grooves. The brush can adapt to radial sliding, accommodating different gear diameters (within 100mm) while avoiding interference between the brush and the gear during lifting and lowering.

[0021] 3. During the drying process, air jet nozzles are also installed at the cylinder cover to enhance the drying effect. The air jet direction is designed so that the air jet nozzles are inclined downward and diffuse from the center to the surrounding area, which can blow the residual moisture on the upper surface of the gear from the center to the edge of the gear, accelerating the falling and evaporation of the residual moisture.

[0032] The present invention will be further described in detail below with reference to the embodiments. It should be understood that the terms "upper", "lower", "front", "rear", "left", "right", "top", "bottom", "inner", "outer" etc. indicated by the coordinate system of the accompanying drawings are based on the orientation or positional relationship shown in the drawings. They are only for the convenience of describing the present invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on the present invention.

[0033] This embodiment proposes an integrated cleaning and drying device for large gears. For example... Figure 1 and Figure 2As shown, this is a large gear processed by the applicant. The device in this embodiment is used to clean and dry this type of gear. It can also be adjusted appropriately to clean and dry other gears of similar size. Figure 1 and Figure 2 The gear center is provided with a mounting hole and a keyway.

[0034] like Figures 3 to 5 As shown, the device includes a base 1, a cleaning cylinder 2, a cylinder cover 14, and a truss 12 from bottom to top. The cleaning cylinder 2 is installed and fixed on the base 1. The truss 12 is provided with a cylinder cover lifting mechanism 13. The lifting end of the cylinder cover lifting mechanism 13 is fixed to the cylinder cover 14. The cylinder cover 14 is closed or opened by the cylinder cover lifting mechanism 13.

[0035] The bottom center of the cleaning cylinder 2 has a mounting hole 1. A lifting cylinder 3 is mounted on the mounting hole 1 via a bearing. The piston end of the lifting cylinder 3 is located inside the cleaning cylinder 2, and a gear fixing shaft 4 is mounted on its top end. The gear fixing shaft 4 is used to fix the gear 5 to be cleaned. The cylinder body end of the lifting cylinder 3 protrudes downward from the bottom of the cleaning cylinder 2 and is provided with a fixing wheel shaft 301. The upper end of the fixing wheel shaft 301 is fixed to the bottom end of the cylinder body of the lifting cylinder 3, and the lower end of the fixing wheel shaft 301 is rotatably connected to the base 1 via a bearing. Through the above design, the lifting cylinder 3 can rotate relative to the cylinder body. A servo motor 801 is mounted on the base 1 as a rotating unit. A synchronous pulley 802 is fixed on the motor shaft of the servo motor 801, and a synchronous pulley 302 is fixed on the fixing wheel shaft 301. The synchronous pulley 802 and the synchronous pulley 302 are connected by a synchronous belt 803. Driven by the servo motor 801, the lifting cylinder 3 can be rotated.

[0036] based on Figure 1 and Figure 2 A key is provided on the gear fixing shaft 4 to achieve keyway connection with the gear. At the same time, a limiting support plate 11 with an outer diameter larger than that of the gear fixing shaft 4 is provided between the gear fixing shaft 4 and the piston end of the lifting cylinder 3 to restrict the gear on the gear fixing shaft 4.

[0037] The cleaning cylinder 2 is divided into a drying zone 201 located at the top and a cleaning zone 202 located at the bottom. The drying zone 201 is provided with a hot air module 6 in the circumference for drying the cleaned gears. The cleaning zone 202 is provided with a brush module 7 in the circumference for brushing the tooth grooves of the gears 5 to be cleaned. The cleaning zone 202 is also provided with a water inlet module and a water outlet module (the water inlet and outlet modules are not shown in the figure, as this is prior art and will not be described in detail).

[0038] like Figure 5As shown, the cylindrical brush module 7 includes a vertically arranged cylindrical brush body 701. The cylindrical brush body 701 includes a central shaft 7011, a sleeve 7012, and bristles 7013. The central shaft 7011 is located inside the sleeve 7012 and is connected to the sleeve 7012 via a bearing. The bristles 7013 are densely distributed on the outer wall of the sleeve. The cylindrical brush module 7 includes a first sliding groove 702 located above the cylindrical brush body 701, a second sliding groove (the second sliding groove is opened on the bottom surface of the cylinder, not shown in the figure) located below the cylindrical brush body 701, a spring push rod 703, and an electric push rod 704. The upper end of the central shaft 7011 is provided with a first slider 7014 that is slidably connected to the first sliding groove 702, and the lower end of the central shaft 7011 is provided with a second slider 7015 that is slidably connected to the second sliding groove. The sliding direction of the first slider 7014 and the second slider 7015 is arranged radially along the cleaning cylinder 2. The elastic push rod 703 is fixed to the bottom surface of the cleaning cylinder 2 and located between the second slider 7015 and the cylinder wall of the cleaning cylinder 2. Its telescopic end is fixed to the second slider 7015 and is used to push the second slider 7015 to slide towards the lifting cylinder 3. The electric push rod 704 is fixed to the bottom surface of the cleaning cylinder 2 and located between the second slider 7015 and the lifting cylinder 3. The electric push rod 704 and the elastic push rod 703 are located in the same radial direction. The telescopic end of the electric push rod 704 can contact the second slider 7015 and is used to push the second slider 7015 to move towards the cylinder wall of the cleaning cylinder 2.

[0039] In this embodiment, the elastic push rod 703 includes a rod body 7031, a spring 7032, and a rod sleeve 7033 with one end open. One end of the rod body 7031 is located inside the rod sleeve 7033 and a limiting seat is integrally formed at that end. The other end of the rod body 7031 protrudes from the open end of the rod sleeve 7033. The spring 7032 is disposed between the closed end of the rod sleeve 7033 and the limiting seat of the rod body 7031, and is used to push the rod body 7031 out of the rod sleeve 7033.

[0040] The usage process of the above equipment is as follows:

[0041] S1. As Figure 6 As shown, the cylinder cover 14 is lifted to open the cleaning cylinder 2. Inside the cleaning cylinder 2, the lifting cylinder 3 is lifted, so that the fixed end of the rotating shaft is close to the top surface of the cylinder. At this time, the electric push rod 704 at the cylinder brush module 7 extends out and pushes the slider 7015 to push the cylinder brush body 701 to the cylinder wall side, so that the distance between the cylinder brushes inside the cleaning cylinder 2 is increased, which makes it easier for the cleaning gear 5 to descend in the next step, so that the gear will not interfere too much with the cylinder brush body 701.

[0042] S2. The worker installs the gear to be cleaned onto the gear fixing shaft 4 by means of keyway fitting (the installation can be done manually, or with the help of other existing mechanical equipment, or even by developing new auxiliary installation equipment), and the cylinder cover 14 is lowered to close the cleaning cylinder 2.

[0043] S3. For example Figure 7 As shown, the lifting cylinder 3 descends, and the gear, under the action of gravity, follows and descends into the cleaning zone 202. At this time, the electric push rod 704 at the cylindrical brush module 7 retracts, and the slider 7015 is pushed by the elastic push rod 703, causing the cylindrical brush body 701 to be pushed towards the gear side until the bristles 7013 contact the gear teeth or tooth grooves, making the elastic push rod 703 unable to push.

[0044] S4. Fill the cleaning tank 2 with cleaning water until it covers the gears;

[0045] S5. Servo motor 801 starts, driving lifting cylinder 3 to rotate via synchronous pulley and synchronous belt, thereby driving gear to rotate. Servo motor 801 can drive gear to rotate in alternating forward and reverse directions. During the rotation of gear, the surrounding water rotates. Through the water flow and the water impact caused by forward and reverse rotation, residual cutting fluid, metal shavings, oil stains and small particles and other contaminants are cleaned away. In addition, during the rotation of gear, the outer bristles 7013 will brush the teeth and tooth grooves of gear, mimicking manual brushing of gear tooth grooves, thus improving the cleanliness of gear.

[0046] S6. For example Figure 8 As shown, after a certain cleaning time, the servo motor 801 stops, and then the brush module 7 returns to normal. Figure 6 As shown, lifting cylinder 3 rises, driving the gear to rise to drying zone 201. Hot air module 6 in drying zone 201 starts, and servo motor 801 starts rotating again. The hot air in drying zone 201 forms a hot vortex under the action of gear rotation, which wraps around the gear and accelerates the drying of the gear.

[0047] S7. After drying is complete, the servo motor 801 and hot air module 6 stop, the cylinder cover 14 is lifted, and the worker removes the gear.

[0048] In addition, to ensure the stability of the equipment when the gears rotate, such as Figure 4 As shown, the bottom surface of the cleaning cylinder 2 is provided with several mounting holes circumferentially around mounting hole one. Mounting holes two are located between mounting hole one and the brush module 7. A lifting cylinder two 9 is fixed in each mounting hole two. The piston end of lifting cylinder two 9 is located inside the cleaning cylinder 2, and its end is fixed with a universal ball joint 10 for supporting the gear 5 to be cleaned. The cylinder body end of lifting cylinder two 9 protrudes downwards from the bottom of the cleaning cylinder 2 and is fixed to the base 1. During cleaning and drying, lifting cylinder two 9 and lifting cylinder one 3 move up and down synchronously, ensuring that the universal ball joint 10 is always supported on the lower surface of the gear. The design of the universal ball joint 10 ensures that the friction between the bottom surface of the gear and the universal ball joint 10 is rolling friction, resulting in low resistance.

[0049] During drying, more cleaning liquid will inevitably remain on the upper surface of the gears. Although the residual liquid will be flung outwards by centrifugal force as the gears rotate, the gears are relatively heavy, and the rotation speed during cleaning and drying will not be very high. Therefore, the centrifugal force will not be strong enough to remove all the residual water. Preferably, such as... Figure 6 and Figure 8 As shown, in this embodiment, a plurality of air nozzles 15 are arranged on the cylinder cover 14. The air jet direction of the air nozzles 15 is inclined downward and diffuses from the center to the surrounding area. The cylinder cover 14 is provided with an air supply channel communicating with the air nozzles 15. An air pump supplies air to the air nozzles 15 through the air supply channel to realize air jetting. The air nozzles 15 can blow the residual moisture on the upper surface of the gear from the center to the edge of the gear, accelerating the falling and evaporation of the residual moisture.

[0050] The above embodiments are only used to explain the concept of this utility model, and are not intended to limit the protection of this utility model. Any non-substantial modifications made to this utility model using this concept should fall within the protection scope of this utility model.
