Description

Technical Field

[0001] This utility model belongs to the field of mechanical technology, and in particular relates to a surface drying treatment device for a speed reducer after cleaning. Background Technology

[0002] Speed ​​reducers play a crucial role in matching speeds and transmitting torque between a prime mover and a driven machine or actuator, and are widely used in modern machinery. Speed ​​reducers can be broadly classified into two categories based on their application: general-purpose speed reducers and special-purpose speed reducers. Their design, manufacturing, and usage characteristics differ significantly. A speed reducer is an independent, closed-loop transmission device between a prime mover and a driven machine or actuator. Its main function is to match speeds (in most cases, reducing speed; in a few cases, it is used to increase speed, called a speed increaser) and increase torque to meet the speed and torque requirements of the driven machine. For example, prime movers (such as motors or engines) typically operate at higher speeds (e.g., motor speeds around 1500 rpm), while driven machines (such as conveyors or mixers) require lower speeds (e.g., tens to hundreds of rpm). Speed ​​reducers achieve speed conversion through transmission mechanisms such as gears or worm gears. In maintenance and manufacturing scenarios, speed reducers may require cleaning to remove surface impurities for better operation. However, even after cleaning, the following drawbacks remain:

[0003] The reducer has a complex structure with components such as gears, bearings, and housing. After cleaning, a large amount of water is distributed on its outer wall, which needs to be dried quickly and over a large area. However, most of these drying devices have insufficient drying area and cannot dry in all directions. Moreover, the water blown off can easily remain on the platform supporting the reducer, causing a large amount of water to still adhere to the bottom surface of the reducer.

[0004] Secondly, after cleaning the reducer, there may still be moisture in its internal cavity. Moisture may remain in the gaps and grooves between the internal mechanical structures. Considering that the reducer usually has lubrication holes and sealing surfaces, air drying is safer than high-temperature drying. However, the reducer only has some small holes, making it difficult to blow the moisture inside. In addition, the airflow generated by air drying is difficult to accurately enter the reducer's interior, and the airflow is difficult to fully cover the complex internal cavity. Utility Model Content

[0005] The purpose of this utility model is to provide a surface drying treatment device for a speed reducer after cleaning. By setting up a treatment box, a support component, an arc-shaped hollow plate, a support arm one, a support arm two, an extension tube, and a Venturi nozzle, it solves the problems that the speed reducer shell cannot be dried quickly over a large area, that the water blown off by the air dryer is easy to accumulate on the support surface of the speed reducer, and that the water in the complex internal cavity of the speed reducer is not easy to dry.

[0006] To solve the above-mentioned technical problems, this utility model is achieved through the following technical solution:

[0007] This utility model is a surface drying treatment device for a speed reducer after cleaning, including a treatment box, an air pipe, an arc-shaped hollow disc, a support component, a support arm one and a support arm two. The bottom of the treatment box is provided with a slope, and two sliding rods are fixed between the two inner end walls of the treatment box. Two support components are slidably arranged on the two sliding rods. An arc-shaped hollow disc is fixed on the inner side wall of the treatment box, and flat air nozzles are fixedly arranged at equal intervals on the inner arc surface of the arc-shaped disc.

[0008] Two hinges are fixed on the inner wall of the processing box next to the arc-shaped hollow disk. Each hinge has a support arm 1 hinged to it. The end of the support arm 1 away from the hinge is hinged to the support arm 2. The end of the support arm 2 away from the support arm 1 is vertically and movably connected to the extension tube. The bottom end of the extension tube is fixed with a Venturi nozzle. A magnetic ring is provided on the outside of the Venturi nozzle.

[0009] Furthermore, a door is hinged to the front of the processing box, and a drainage trough is provided at the bottom of the processing box. The drainage trough is connected to the lower side of the slope. A drainage pipe is fixed through the end wall of the processing box at one end of the drainage trough and is connected to the drainage trough.

[0010] Furthermore, two symmetrically distributed mounting ears are fixed to the upper rear side of the processing box, and an air tube is fixed in both mounting ears. An air filter is fixed to one end of the air tube.

[0011] Furthermore, a branch pipe is fixedly connected to the outer arc surface of the arc-shaped hollow disk, and the end of the branch pipe away from the arc-shaped hollow disk passes through the processing box and is fixedly connected to the periphery of the air pipe.

[0012] Furthermore, a Y-shaped tube is fixedly connected to the upper ends of the two extension tubes, and the end of the Y-shaped tube away from the extension tube passes through the treatment box and is fixed to the periphery of the air pipe. A limit ring is fixed to the upper periphery of the Y-shaped tube.

[0013] Furthermore, the supporting component includes a base plate and a tray above the base plate. A motor is fixed at the bottom center of the base plate, and the output shaft of the motor passes through the base plate and is fixed at the bottom center of the tray. Equidistant columns are fixed on the upper surface of the tray.

[0014] Furthermore, each of the four corners of the bottom surface of the substrate is fixed with an arc-shaped clamp, and the arc-shaped clamp is held outside the slide rod.

[0015] This utility model has the following beneficial effects:

[0016] This invention solves the problems of slow reducer shells not being able to be dried quickly over a large area, and the moisture blown off during drying easily accumulating on the surface supporting the slow reducer, by setting up a processing box, a support component, and an arc-shaped hollow disc. The slow reducer to be dried is placed on the support component inside the arc-shaped hollow disc. An air pipe is connected to an air source, and the airflow for drying is input. It enters the arc-shaped hollow disc through a branch pipe and is then sprayed out from a large number of flat nozzles, blowing onto the surface of the slow reducer. At the same time, the support component is held on a slide rod by an arc-shaped clamp at the bottom of the base plate. The motor drives the tray to rotate, and the slow reducer is placed on the tray. The rotation of the tray drives the rotation of the slow reducer, so that the arc-shaped hollow disc can dry the outer surface of the slow reducer from all directions, and the blown-off moisture will not adhere to the bottom surface of the slow reducer. A large number of columns are set on the tray, and the slow reducer is placed on the columns and suspended, without contacting the surface of the tray. Subsequently, the slow reducer can be flipped over to quickly dry the bottom surface as well.

[0017] This invention solves the problem of moisture not easily drying in the complex internal cavity of a reducer by setting up a first support arm, a second support arm, an extension tube, and a Venturi nozzle. Because the first support arm is hinged to the hinge and can rotate, and the second support arm is also hinged to the first support arm and can rotate, the position of the extension tube can be changed at will. In this process, it can be adapted to the opening on the reducer of any size. The Venturi nozzle at the bottom of the extension tube is aligned with the opening of the reducer and fixed by magnetic ring adsorption to maintain stability. The Venturi nozzle design can increase the airflow velocity, speed up the drying efficiency, and allow the airflow to quickly and fully enter the internal cavity of the reducer, making it suitable for drying operations in complex internal cavities.

[0018] This invention incorporates an air pipe and an air filter. The air pipe is connected to an air source (such as an air compressor) via the air filter, ensuring that the airflow used for drying does not contain new impurities and will not further damage the reducer. The airflow used for drying is filtered through the air filter to prevent the introduction of new impurities. A heating element can also be installed inside the air pipe to heat the airflow and achieve drying operations at a certain temperature. Attached Figure Description

[0029] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention.

[0030] Please see Figures 1-7 As shown, this utility model is a surface drying treatment device for a speed reducer after cleaning, including a treatment box 1, an air pipe 2, an arc-shaped hollow disk 3, a support component 4, a first support arm 5 and a second support arm 6. The bottom of the treatment box 1 is provided with a ramp 106. Two sliding rods 105 are fixed between the two inner end walls of the treatment box 1. Two support components 4 are slidably arranged on the two sliding rods 105. An arc-shaped hollow disk 3 is fixed on the inner side wall of the treatment box 1, and flat nozzles 302 are equidistantly distributed on the inner arc surface of the arc-shaped disk.

[0031] The entire drying process takes place inside the treatment box 1, which isolates it from secondary pollution such as external dust and reduces noise transmission. The treatment box 1 is equipped with a ramp 106, and the water droplets blown down slide down the ramp 106. The treatment box 1 is equipped with a slide rod 105 to support the support assembly 4, which is used to support the reducer. The two support assemblies 4 can support two reducers, and the drying of the outer wall and inner cavity of the reducer can be carried out simultaneously. The drying airflow introduced by the arc-shaped hollow plate 3 is finally sprayed out from the flat nozzle 302 and blown towards the outer surface of the reducer.

[0032] Two hinges 104 are fixed on the inner wall of the processing box 1 next to the arc-shaped hollow disk 3. Each hinge 104 is hinged to a support arm 5. The end of the support arm 5 away from the hinge 104 is hinged to a support arm 6. The end of the support arm 6 away from the support arm 104 is vertically and movably connected to an extension tube 7. The bottom end of the extension tube 7 is fixed with a Venturi nozzle 701. A magnetic ring 7011 is provided on the outside of the Venturi nozzle 701.

[0033] The first support arm 5 is connected by the hinge 104. The first support arm 5 and the second support arm 6 are also hinged, allowing them to move at a great angle and within a wide range, thus adapting to the openings on various sizes of reducers. The extension tube 7 can be moved up and down within the second support arm 6, making it suitable for reducers of different heights. The extension tube 7 is moved so that the venturi nozzle 701 at its bottom is aligned with the opening on the reducer, and is held in place by the magnetic ring 7011. This allows high-speed airflow to be blown into the inner cavity of the reducer and then discharged from another opening, quickly removing the internal moisture.

[0034] The front side of the processing box 1 is hinged to a door 101. The bottom of the processing box 1 is also provided with a drainage trough 103, and the drainage trough 103 is connected to the lower side of the slope 106. A drainage pipe 1031 is fixed through the end wall of the processing box 1 at one end of the drainage trough 103, and the drainage pipe 1031 is connected to the drainage trough 103.

[0035] The door 101 closes the front of the processing box 1 and is only opened when the reducer is taken out or put in. The water blown down from inside enters the drainage trough 103 along the slope of the ramp 106 and is then discharged from the drain pipe 1031. The top of the processing box 1 is equipped with an exhaust device (exhaust port, exhaust fan, etc., not shown in the figure).

[0036] Two symmetrically distributed mounting ears 102 are fixed on the upper rear side of the processing box 1, and an air tube 2 is fixed in both mounting ears 102. An air filter 201 is fixed at one end of the air tube 2.

[0037] The air pipe 2 is installed using two mounting ears 102 and connected to the air filter 201 to filter the airflow used for drying, thus preventing the introduction of new impurities into the reducer and damaging it.

[0038] A branch pipe 301 is fixed through the outer arc surface of the arc-shaped hollow disk 3, and the end of the branch pipe 301 away from the arc-shaped hollow disk 3 passes through the processing box 1 and is fixed through the periphery of the air pipe 2.

[0039] The arc-shaped hollow disk 3 is connected to the air pipe 2 by the branch pipe 301, so that the airflow enters the arc-shaped hollow disk 3.

[0040] The upper ends of the two extension tubes 7 are connected and fixed with a Y-shaped tube 703. The end of the Y-shaped tube 703 away from the extension tube 7 passes through the treatment box 1 and is connected and fixed to the periphery of the air tube 2. A limit ring 702 is fixed on the upper periphery of the Y-shaped tube 703.

[0041] The limiting ring 702 allows the extension tube 7 to have a maximum descent height, preventing it from falling out of the support arm 2 6 when the extension tube 7 is not in operation. The air pipe 2 is connected through the Y-shaped pipe 703, and the air is introduced into the two extension tubes 7. The Venturi nozzle 701 on the extension tube 7 blows air to dry the openings at various positions on the reducer.

[0042] The supporting component 4 includes a base plate 402 and a tray 401 above the base plate 402. A motor 403 is fixed at the bottom center of the base plate 402. The output shaft of the motor 403 passes through the base plate 402 and is fixed at the bottom center of the tray 401. Columns 4011 are fixed at equal intervals on the upper surface of the tray 401.

[0043] Arc-shaped clips 4021 are fixed at the four corners of the bottom surface of the substrate 402, and the arc-shaped clips 4021 are clamped to the outside of the slide bar 105;

[0044] When placing the support component 4, first clamp the arc-shaped clamp 4021 outside the slide bar 105 to restrict the position, and then place the reducer on the column 4011 on the tray 401 to suspend it. During operation, the motor 403 drives the tray 401 to rotate, making it rotate to facilitate full air drying.

[0045] The specific working principle of this utility model is as follows: First, place the support component 4, clamp the arc-shaped clamp 4021 outside the slide bar 105, place the reducer on the column 4011 on the tray 401 so that it is suspended in the air, slide the base plate 402 so that it is placed inside the arc-shaped hollow disk 3, at this time, close the box door 101, and connect the air pipe 2 to the air source (such as an air compressor) through the air filter 201 so that the airflow used for drying does not contain new impurities. The airflow enters the arc-shaped hollow disk 3 from the branch pipe 301, and then sprays out from a large number of flat nozzles 302, blowing towards the surface of the reducer. At the same time, the motor 403 drives the tray 401 to rotate, and the rotation of the tray 401 drives the reducer to rotate, so that the arc-shaped hollow disk 3 can dry the outer surface of the reducer in all directions. The water blown down slides down the slope 106, enters the drain trough 103 and is discharged from the drain pipe 1031. After the outer surface of the device is dried, slide the support assembly 4 and place it under the support arm 5 and support arm 6 (at the same time, another set of support assemblies 4 can be placed on the reducer for outer surface drying, as described above). Then, align the Venturi nozzle 701 at the bottom of the extension tube 7 with the opening of the reducer and fix it with magnetic ring 7011 to maintain stability. Move the extension tube 7, which can move up and down inside the support arm 6, to be suitable for reducers of different heights. Move the extension tube 7 so that the Venturi nozzle 701 at the bottom of the reducer is aligned with the opening on the reducer and fix it with magnetic ring 7011 to maintain stability. Connect the air pipe 2 through the Y-shaped tube 703 and input airflow into the two extension tubes 7. The Venturi nozzle 701 on the extension tube 7 blows air to dry the openings at various positions on the reducer, so that the high-speed airflow can be blown into the inner cavity of the reducer and then discharged from another opening to quickly remove the internal moisture.

[0046] The above are merely preferred embodiments of the present utility model and do not limit the present utility model. Any modifications, equivalent substitutions, or improvements made to the technical solutions described in the foregoing embodiments, or to some of the technical features, shall fall within the protection scope of the present utility model.
