Abstract
Description
Technical Field
[0001] The invention relates to the technical field of automobile assembly, in particular to a reducer oil removal tank. Background Art
[0002] After assembly, a vehicle's final reducer undergoes NVH (Noise, Vibration, Harshness) performance testing to determine its compliance. However, residual mechanical lubricant will remain on the final reducer after the vibration test. Due to its viscosity, the oil absorbs dust from the air and impurities such as iron filings generated during the assembly process. These impurities significantly reduce the final reducer's qualification rate during subsequent assembly. Summary of the Invention

[0005] Furthermore, the rotating disk includes a lower driving disk and an upper supporting disk whose central axes coincide with each other. The lower driving disk is driven to rotate by a motor. The upper supporting disk is arranged on the lower driving disk through a support rod. There is a distance between the upper supporting disk and the lower driving disk.
[0006] Furthermore, the packaging device is provided on the upper surface of the lower driving disk, and the packaging device is located in the middle of the lower driving disk, and the upper supporting disk is provided with a clearance hole for the film of the packaging device to pass through.
[0007] Furthermore, the bottom of the inner cylinder is fixedly connected to the upper supporting plate by bolts.
[0008] Furthermore, the diameter of the upper supporting plate is smaller than the diameter of the bottom of the inner cylinder, and the distance between the oil outlet hole at the bottom of the inner cylinder and the center of the circle of the bottom of the inner cylinder is greater than the radius of the upper supporting plate.
[0009] Furthermore, the oil outlet hole at the bottom of the inner cylinder is an arc-shaped strip hole.
[0010] Furthermore, an end cover is provided at the upper end of the inner cylinder, the end cover is fixedly connected to the inner cylinder, the through hole is provided on the end cover, and the upper end surface of the end cover is used to be fixedly connected to the housing of the reducer.
[0011] Furthermore, a mounting flange is provided at the upper end of the inner tube, and the end cover is fixedly connected to the mounting flange by bolts.
[0012] Furthermore, the packaging device includes a film box, a blower and a cutting knife, the cutting knife corresponds to the film outlet of the film box, and the blower is arranged below the film box to blow the film coming out of the film box to the surface of the gear mechanism of the reducer for coating.
[0013] Furthermore, an oil drain valve is provided at the oil drain hole of the outer cylinder.
[0014] The above technical solution is adopted: it includes an outer cylinder and an inner cylinder, the inner cylinder includes a accommodating cavity, the accommodating cavity is used to accommodate the gear mechanism of the reducer, the upper end of the inner cylinder is used to be fixedly connected to the housing of the reducer, and a through hole is provided at the upper end of the inner cylinder for the gear mechanism to extend into the accommodating cavity; the inner cylinder is located inside the outer cylinder, and a rotating disk is provided in the middle of the bottom of the outer cylinder, the rotating disk is driven to rotate by a motor, the inner cylinder is fixedly connected to the rotating disk and driven to rotate by the rotating disk, the central axis of the inner cylinder coincides with the central axis of the rotating disk, the side wall and bottom of the inner cylinder are provided with multiple oil outlet holes, the bottom of the outer cylinder is provided with an oil drain hole, the bottom of the inner cylinder is provided with a through hole, a packing device is provided below the through hole, and the packing device is fixed to the rotating disk. When performing the degreasing operation, the gear mechanism of the reducer is passed through the through hole of the degreasing tank and extended into the accommodating cavity of the inner cylinder, and then the housing of the reducer is fixed. The motor is then activated to rotate the rotating disk, which in turn drives the reducer. The resulting centrifugal force ejects the lubricating oil from the reducer, which is then discharged through the oil outlet holes in the inner and outer cylinders. After degreasing, the packaging device beneath the inner cylinder begins operation. The packaging device's film enters the accommodating chamber through the through-holes at the bottom of the inner cylinder. Because the surface of the reducer's gear mechanism is moist, the film adheres stably and covers the gear mechanism, providing protection. This degreasing tank allows the inspected reducer to be degreased, ensuring the cleanliness of the entire product. Furthermore, the packaging device's film coating prevents the adhesion of dust and impurities to the reducer's gear mechanism during subsequent processes, improving the pass rate in the subsequent assembly of the main reducer.
[0015] Furthermore, the rotating disk includes a lower drive disk and an upper support disk whose central axes coincide with each other. The lower drive disk is driven for rotation by a motor, and the upper support disk is mounted on the lower drive disk via support rods, with a gap between the upper support disk and the lower drive disk. The upper support disk is mounted on the lower drive disk via the support rods, which not only ensures that the inner cylinder is sufficiently high relative to the bottom of the outer cylinder, but also reduces the overall mass of the rotating disk.
[0016] Furthermore, the packaging device is mounted on the upper surface of the lower drive disk, located in the middle of the lower drive disk. The upper support disk is provided with a clearance hole for the packaging device's film to pass through. This simplifies installation of the packaging device, ensuring effective operation without affecting the rotation of the inner drum. The clearance hole corresponds to a through-hole in the bottom of the inner drum.
[0017] Furthermore, the bottom of the inner cylinder is fixedly connected to the upper support plate by bolts. The upper support plate facilitates the installation, disassembly and adjustment of the inner cylinder.
[0018] Furthermore, the diameter of the upper support plate is smaller than the diameter of the bottom of the inner cylinder, and the distance between the oil outlet hole at the bottom of the inner cylinder and the center of the circle of the bottom of the inner cylinder is greater than the radius of the upper support plate, thereby ensuring effective oil discharge from the oil outlet hole at the bottom of the inner cylinder.
[0019] Furthermore, the oil outlet holes at the bottom of the inner cylinder are arc-shaped strip holes. The strip holes can ensure a sufficiently large oil outlet hole area while the number of oil outlet holes can be relatively reduced, thereby reducing the processing steps.
[0020] Furthermore, an end cap is provided at the upper end of the inner cylinder, which is fixedly connected to the inner cylinder. The through hole is provided on the end cap, and the upper end surface of the end cap is used to be fixedly connected to the housing of the reducer. The provision of the through hole on the end cap allows the end cap to be replaced according to different models of reducers, expanding the applicability of the oil removal tank. When changing models, the corresponding end cap can be directly replaced.
[0021] Furthermore, a mounting flange is provided at the upper end of the inner tube, and the end cover is fixedly connected to the mounting flange by bolts. The mounting flange facilitates the installation of the end cover.
[0022] Furthermore, the packaging device includes a film box, a blower, and a cutter. The cutter corresponds to the film outlet of the film box. The blower is located below the film box and is used to blow the film from the film box onto the surface of the gear mechanism of the reducer for coating. During packaging, the film box is driven to extend from the outlet of the film box. The extended film, driven by the blower, passes upward through the through-holes in the bottom of the inner cylinder and protects the gear mechanism. Finally, the cutter cuts the film, making the packaging device simple and reliable.
[0023] Furthermore, an oil drain valve is provided at the oil drain hole of the outer cylinder, so that the discharge of the lubricating oil can be controlled, which is more conducive to the collection and treatment of the lubricating oil.
[0024] The de-oiling tank removes oil from the inspected reducer, ensuring the cleanliness of the entire product. Furthermore, after lamination by the packaging device, dust and impurities are prevented from adhering to the reducer gear mechanism during subsequent processes, improving the pass rate of the final reducer assembly.

DETAILED DESCRIPTION
[0030] See also Figures 1 to 3 A de-oiling tank for a reducer includes an outer cylinder 1 and an inner cylinder 3, and the outer cylinder 1 and the inner cylinder 3 are made of metal. The inner cylinder 3 includes a housing chamber, and the housing chamber is used to accommodate the gear mechanism of the reducer. The upper end of the inner cylinder 3 is used to be fixedly connected to the housing of the reducer. A through hole 11 is provided at the upper end of the inner cylinder 3 for the gear mechanism to extend into the housing chamber. An end cover 2 is provided at the upper end of the inner cylinder 3, and the end cover 2 is fixedly connected to the inner cylinder 3. The through hole 11 is provided on the end cover 2, and the upper end surface of the end cover 2 is used to be fixedly connected to the housing of the reducer. The through hole 11 is provided on the end cover 2, so that the end cover 2 can be replaced according to different models of reducers, thereby expanding the scope of application of the de-oiling tank. When changing the model, the corresponding end cover 2 can be directly replaced. A mounting flange 7 is provided at the upper end of the inner cylinder 3, and the end cover 2 is fixedly connected to the mounting flange 7 by bolts. The mounting flange 7 facilitates the installation of the end cover 2.
[0031] In this embodiment, the inner cylinder 3 is positioned within the outer cylinder 1. A rotating disk is located in the middle of the bottom of the outer cylinder 1. The rotating disk is driven by a motor, and the inner cylinder 3 is fixedly connected to the rotating disk, driven by the rotating disk. The central axis of the inner cylinder 3 coincides with the central axis of the rotating disk. The rotating disk comprises a lower drive disk 8 and an upper support disk 9, whose central axes coincide with each other. The lower drive disk 8 is driven by a motor, and the upper support disk 9 is mounted on the lower drive disk 8 via support rods, with a gap between the upper support disk 9 and the lower drive disk 8. The upper support disk 9 is mounted on the lower drive disk 8 via support rods, ensuring that the inner cylinder 3 has sufficient height relative to the bottom of the outer cylinder 1 while also reducing the overall mass of the rotating disk. The bottom of the inner cylinder 3 is fixedly connected to the upper support disk 9 via bolts, which facilitates installation, removal, and adjustment of the inner cylinder 3. Multiple oil outlet holes 5 are provided on the sidewalls and bottom of the inner cylinder 3, and an oil drain hole 4 is provided at the bottom of the outer cylinder 1. Specifically, the oil outlet holes 5 at the bottom of the inner cylinder 3 are arc-shaped strip holes. This ensures a sufficiently large area for the oil outlet holes 5 while reducing the number of oil outlet holes 5, thus simplifying the manufacturing process. Furthermore, the diameter of the upper support plate 9 is smaller than the diameter of the bottom of the inner cylinder 3, and the distance between the oil outlet holes 5 at the bottom of the inner cylinder 3 and the center of the bottom of the inner cylinder 3 is greater than the radius of the upper support plate 9. This ensures effective oil discharge from the oil outlet holes 5 at the bottom of the inner cylinder 3. Furthermore, an oil drain valve is provided at the oil drain hole 4 of the outer cylinder 1. This drain valve allows for controllable discharge of lubricating oil, further facilitating its collection and processing.
[0032] In this embodiment, a through hole 6 is provided at the bottom of the inner cylinder 3, and a packing device 10 is provided below the through hole 6. The packing device 10 is fixed on the rotating disk. Furthermore, the packing device 10 is provided on the upper surface of the lower driving disk 8, and the packing device 10 is located in the middle of the lower driving disk 8. The upper supporting disk 9 is provided with a clearance hole for the film of the packing device 10 to pass through. The installation of the packing device 10 is simplified, and the effective operation of the packing device 10 can be ensured without affecting the rotation of the inner cylinder 3. The clearance hole corresponds to the through hole 6 at the bottom of the inner cylinder 3. The packing device 10 includes a film box 101, a blower 103 and a cutting knife 102. The cutting knife 102 corresponds to the film outlet of the film box 101. The blower 103 is provided below the film box 101 and is used to blow the film coming out of the film box 101 to the surface of the gear mechanism of the reducer for coating. During packaging, the film box 101 drives the film to extend from the outlet of the film box 101. The extended film is blown upward through the through hole 6 at the bottom of the inner tube 3 by the blower 103, and covers the gear mechanism to form protection. Finally, the film is cut by the cutting knife 102. The packaging device 10 is simple and reliable.
[0033] During the degreasing operation, the reducer's gear mechanism is inserted through the through-hole 11 of the degreasing tank and into the housing of the inner cylinder 3. The reducer housing is then secured. The motor is then operated to rotate the rotating disk, which in turn rotates the reducer. The resulting centrifugal force dislodges the lubricating oil adhering to the reducer. The oil is then discharged through the oil outlet 5 in the inner cylinder 3 and the oil drain hole 4 in the outer cylinder 1. After degreasing, the packaging device 10 below the inner cylinder 3 begins operation. The film of the packaging device 10 enters the housing through the through-hole 6 at the bottom of the inner cylinder 3. Because the surface of the reducer's gear mechanism is moist, the film adheres stably to the gear mechanism, thus protecting it. This degreasing tank allows the degreasing of the reduced unit after inspection, thereby ensuring the cleanliness of the entire product. Furthermore, the film coating of the packaging device prevents the adhesion of dust and impurities to the reducer's gear mechanism during subsequent processes, thereby improving the pass rate of the final reducer assembly.
