Description

Technical Field

[0001] This utility model relates to the field of gear weathering test technology, and in particular to a salt spray test chamber for testing the weathering resistance of precision gears. Background Technology

[0002] A salt spray test chamber, used in gear weathering tests, is a device that simulates a salt spray environment to evaluate the corrosion resistance of gears. The salt spray test chamber atomizes a salt solution of a certain concentration and then evenly distributes the salt spray inside the test chamber, exposing the gears to a humid environment containing salt. Under this environment, an electrochemical reaction occurs on the gear surface, accelerating the corrosion process. This simulates the harsh salt spray environment that gears may encounter in actual use, thus conducting weathering tests on the gears.

[0003] Currently, when using salt spray test chambers to test the weather resistance of gears, the gear samples are mostly placed directly onto the sample rack inside the chamber. This results in the salt spray not being evenly distributed over the surface of the gear samples, thus affecting the accuracy of the test results. To address this issue, we propose a salt spray test chamber for testing the weather resistance of precision gears. Utility Model Content

[0004] The purpose of this invention is to provide a salt spray test chamber for weathering resistance testing of precision gears, so as to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution:

[0006] A salt spray test chamber for weathering resistance testing of precision gears includes a salt spray test chamber body. A spray mechanism is installed on the inner top wall of the salt spray test chamber body. A sealed bearing is embedded in the inner side wall of the salt spray test chamber body. A gear sleeve rod is connected to the inner ring of the sealed bearing. A drive motor is installed at one end of the gear sleeve rod. A brine container is connected to the back of the salt spray test chamber body. A liquid injection port is connected to the upper surface of the brine container. A liquid delivery mechanism is installed inside the brine container. Two sealed doors are hinged to the front of the salt spray test chamber body. Each of the two sealed doors has a handle connected to its front.

[0007] In a further embodiment, the spraying mechanism includes an atomizer, the bottom surface of which has a set of atomizing nozzles arranged at equal intervals.

[0008] In a further embodiment, the delivery mechanism includes an infusion pump, the output end of which is connected to an infusion pipe, the output end of which passes through the inner top wall of the saline holding tank and the inner top wall of the salt spray test chamber body in sequence and is connected to the input end of the spray mechanism.

[0009] In a further embodiment, a liquid level observation tank is provided on the back of the brine container, and an observation window is provided inside each of the two sealed doors. Transparent glass is connected to the interior of both observation windows and the interior of the liquid level observation tank.

[0010] In a further embodiment, a support plate is connected to the left side of the salt spray test chamber body, and an arc-shaped seat is connected to the upper surface of the support plate. The upper surface of the arc-shaped seat is connected to the outer surface of the drive motor.

[0011] In a further embodiment, the bottom surface of the salt spray test chamber body is connected to two L-shaped support frames, and each of the two L-shaped support frames has a set of positioning holes inside.

[0012] Compared with the prior art, the beneficial effects of this utility model are:

[0013] This device first utilizes a gear-mounting rod to facilitate the placement of gear samples by operators. Then, a drive motor rotates the gear-mounting rod, which in turn rotates the gear sample. This allows for more even spraying of smoke onto the surface of the gear sample during weathering tests, thereby indirectly improving the accuracy of the weathering resistance test.

Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0022] Please see Figure 1-4In this utility model, a salt spray test chamber for weather resistance testing of precision gears includes a salt spray test chamber body 1. A spray mechanism 2 is installed on the inner top wall of the salt spray test chamber body 1. A sealed bearing 4 is embedded in the inner side wall of the salt spray test chamber body 1. A gear sleeve rod 5 is connected to the inner ring of the sealed bearing 4. A drive motor 6 is installed at one end of the gear sleeve rod 5. A brine container 7 is connected to the back of the salt spray test chamber body 1. A liquid injection port 8 is connected to the upper surface of the brine container 7. A liquid conveying mechanism 3 is installed inside the brine container 7. Two sealed doors 9 are hinged to the front of the salt spray test chamber body 1. Each of the two sealed doors 9 has a handle 10 connected to its front. The spray mechanism 2 includes an atomizer 201. The bottom surface of the atomizing converter 201 is provided with a set of atomizing nozzles 202 arranged at equal intervals. The conveying mechanism 3 includes an infusion pump 301, the output end of which is connected to an infusion pipe 302. The output end of the infusion pipe 302 passes through the inner top wall of the salt water holding tank 7 and the inner top wall of the salt spray test chamber body 1 in sequence and is connected to the input end of the spraying mechanism 2. The outer surface of the gear sleeve rod 5 is provided with two limiting keyways. By using the cooperation of the infusion pump 301 and the infusion pipe 302, the salt water inside the salt water holding tank 7 can be transported to the inside of the spraying mechanism 2. The atomizing converter 201 can convert the salt water into salt mist, and the atomizing nozzles 202 can spray the salt mist evenly onto the surface of the gear sample.

[0023] The back of the brine container 7 has a liquid level observation slot 11. Both sealed doors 9 have observation windows 14 inside. The interiors of both observation windows 14 and the liquid level observation slot 11 are connected to transparent glass. A support plate 12 is connected to the left side of the salt spray test chamber body 1. An arc-shaped seat 13 is connected to the upper surface of the support plate 12. The upper surface of the arc-shaped seat 13 is connected to the outer surface of the drive motor 6. Two L-shaped support frames 15 are connected to the bottom of the salt spray test chamber body 1. Each L-shaped support frame 15 has a set of positioning holes 16 inside. The liquid level observation slot 11 allows staff to easily check the remaining amount of brine inside the brine container 7. The support plate 12 and the arc-shaped seat 13 support the drive motor 6, making its operation more stable. The L-shaped support frames 15 and the positioning holes 16 allow staff to easily fix the salt spray test chamber body 1 to the ground.

[0024] The working principle of this utility model is as follows:

[0025] When using this device, the operator first uses the L-shaped support frame 15 and positioning holes 16 to fix the salt spray test chamber body 1 to the ground, then opens the sealing door 9 and inserts the gear sample to be tested onto the outside of the gear sleeve rod 5, ensuring that the inner ring of the gear sample engages with the keyway on the surface of the sleeve rod 5. This ensures that the inner ring of the gear sample is in close contact with the outer ring of the gear sleeve rod 5. After the gear sample is inserted, the sealing door 9 is closed, and the infusion pump 301 is started using the controller. The infusion pump 301 and infusion tubing 302 then fill the saline solution tank 7. The brine is delivered to the atomizing converter 201, where it is converted into salt mist. After conversion, the salt mist is sprayed onto the surface of the gear sample using the atomizing nozzle 202. Simultaneously, the operator uses the controller to start the drive motor 6, which rotates the gear sleeve rod 5. This, in turn, rotates the gear sample, allowing the atomizing nozzle 202 to spray the salt mist more evenly onto the surface of the gear sample. This completes the weather resistance test on the gear sample. The above is the entire operation procedure of this device.

[0026] It will be apparent to those skilled in the art that this invention is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or essential characteristics of this invention.
