Description

Technical Field

[0001] This utility model relates to the technical field of testing mechanisms, specifically a gear oil viscosity testing mechanism. Background Technology

[0002] Gear oil mainly refers to the lubricating oil used in transmissions and rear axles. It differs from engine oil in terms of usage conditions, composition, and performance. Gear oil primarily lubricates gears and bearings, prevents wear and corrosion, and helps dissipate heat from gears. Automotive gear oil is used in gear transmission mechanisms such as automotive steering systems, transmissions, and drive axles. Due to the high surface pressure during gear transmission, gear oil plays a crucial role in lubrication, anti-wear, cooling, heat dissipation, corrosion and rust prevention, cleaning, and reducing gear surface impact and noise.

[0003] A search revealed a Chinese patent publication number, CN214844627U, which discloses a viscosity testing device for wind turbine gear oil. The device includes a base with support legs fixedly connected to the four corners of the lower end. A slot is opened at the front of the upper end of the base. A left limiting mechanism is fixedly connected to the left side of the upper end of the base, and a right limiting mechanism is fixedly connected to the right side of the upper end of the base. The right limiting mechanism and the left limiting mechanism have the same structure. A measuring cup is provided in the slot.

[0004] Although the above patent is suitable for the use of viscosity testing of wind turbine gear oil, the above device still has the following problems: when the device is not in use, the probe of the device is directly exposed to the external environment. Since the device has no protective structure, objects in the external environment are prone to collision with the probe, causing damage to the probe and reducing the service life of the probe. In view of the above situation, technical innovation is carried out on the basis of the existing device. Utility Model Content

[0022] Please see Figure 1-4 This utility model provides a technical solution: a gear oil viscosity testing mechanism, including a bracket 1, on which a viscometer 2 is mounted. The viscometer 2 is an existing structure and will not be described in detail here. A probe is mounted at the bottom of the viscometer 2. The viscometer 2 can detect the viscosity of gear oil through the probe. A base 17 is fixedly connected to the top of the bracket 1. A container can be placed on the top of the base 17. A first protective shell 3 and a second protective shell 4 are rotatably connected to the bottom of the viscometer 2. Two symmetrical mounting grooves 12 are opened on the side of the second protective shell 4 near the first protective shell 3. Two symmetrical mounting rods 11 are fixedly connected to the side of the first protective shell 3 near the second protective shell 4. The surface of the mounting rods 11 is inserted into the inside of the mounting grooves 12. The mounting rods 11 can slide out and slide into the inside of the mounting grooves 12, thereby positioning the first protective shell 3 and the second protective shell 4.

[0023] The first protective shell 3 and the second protective shell 4 work together to protect the probe of the device and reduce the direct exposure of the probe to the external environment to a certain extent, so that external objects can easily collide with the probe, causing damage to the probe and reducing its service life.

[0024] The second protective shell 4 has a power groove 13 extending into the mounting groove 12. A power frame 14 is slidably connected inside the power groove 13. A fixing groove 16 is provided inside the mounting rod 11. The side of the power frame 14 near the fixing groove 16 is inserted into the fixing groove 16. A second spring 15 is fixedly connected to the top of the power frame 14. The top of the second spring 15 is fixedly connected to the inner wall of the power groove 13. The second spring 15 can be compressed and reset by moving the power frame 14.

[0025] An adjustment groove 19 extending to the outside of the base 17 is provided inside the base 17. A bidirectional threaded rod 18 extending to the outside of the base 17 is rotatably connected inside the adjustment groove 19. Two symmetrical movable frames 20 are slidably connected inside the adjustment groove 19. The inside of the movable frames 20 is threadedly connected to the surface of the base 17. The two movable frames 20 are respectively set on two opposite threads on the surface of the bidirectional threaded rod 18. The cross-section of the movable frame 20 is U-shaped. Arc-shaped grooves are provided on the opposite sides of the two movable frames 20. A rubber layer is provided inside the arc-shaped grooves. After the operator places the container on the top of the base 17, the operator rotates the bidirectional threaded rod 18. Under the restriction of the adjustment groove 19, the bidirectional threaded rod 18 drives the two movable frames 20 to move closer to each other. The two movable frames 20 clamp and fix the container through the arc-shaped grooves and the rubber layer, making the container more stable and enabling the device to more smoothly detect the viscosity of gear oil.

[0026] The first protective shell 3 and the second protective shell 4 are each provided with a movable groove 8 on the side that is relatively far apart from each other. The movable groove 8 is slidably connected to a limit frame 9. The movable groove 8 and the limit frame 9 are both T-shaped in cross section. A positioning block 5 is fixedly connected to one side of the movable groove 8. The top of the positioning block 5 is provided with two symmetrical positioning grooves 6. Positioning rods 7 are fixedly connected to both sides of the viscometer 2. The bottom of the positioning rod 7 is provided with an inclined surface. The surface of the positioning rod 7 is inserted into the inside of the positioning groove 6. The positioning rod 7 can slide into and out of the inside of the positioning groove 6, thereby fixing the position of the first protective shell 3 and the second protective shell 4.

[0027] A first spring 10 is fixedly connected to one side of the limiting frame 9. The side of the first spring 10 away from the limiting frame 9 is fixedly connected to the inner wall of the moving groove 8. The first protective shell 3 and the second protective shell 4 are released by the operator, so that the first protective shell 3 and the second protective shell 4 rotate in sequence. The positioning rod 7 can push the positioning block 5 to move through the inclined surface at the bottom of the positioning rod 7. When the first protective shell 3 rotates to the appropriate position, the first spring 10 pushes the positioning block 5 to move, so that the positioning rod 7 slides into the interior of the positioning groove 6, and the positions of the first protective shell 3 and the second protective shell 4 are fixed, so that the operator can use the viscometer 2 to detect the viscosity of the gear oil through the probe.

[0028] Working principle: For this type of gear oil viscosity testing mechanism, the operator first places the container on top of the base 17, then rotates the bidirectional threaded rod 18. Under the constraint of the adjusting groove 19, the bidirectional threaded rod 18 drives the two moving frames 20 to move closer together, and the two moving frames 20 clamp and fix the container through the arc groove and rubber layer, making the container more stable. After the operator slides the power frame 14 out of the fixed groove 16, the operator releases the first protective shell 3 and the second protective shell 4, allowing the first protective shell 3 and the second protective shell 4 to rotate in sequence. Through the inclined surface at the bottom of the positioning rod 7, the positioning rod 7 can push the positioning block 5 to move. When the first protective shell 3 rotates to the appropriate position, the first spring 10 pushes the positioning block 5 to move, causing the positioning rod 7 to slide into the positioning groove 6, thus fixing the position of the first protective shell 3 and the second protective shell 4. This allows the operator to use the viscometer 2 to test the viscosity of the gear oil through the probe.
