Description

Technical Field

[0001] The utility model relates to the technical field of reduction gearboxes, in particular to an immersion painting suspension device for a reduction gearbox. Background Art

[0002] The functions of immersion painting for the reduction gearbox are mainly reflected in the following aspects: 1) Rust prevention and anti-corrosion: The reduction gearbox usually operates in various complex environments, including humid, dusty or corrosive environments. Under these conditions, the outer shell and internal components of the gearbox are prone to corrosion and oxidation, which will affect its performance and service life. Immersion painting suspension can form a protective coating to effectively isolate moisture, oxygen and corrosive substances in the external environment, thus reducing the corrosion risk and extending the service life of the gearbox. 2) Enhancing durability: The immersion paint not only provides an anti-corrosion barrier, but also enhances the durability by increasing the hardness and wear resistance of the gearbox outer shell. This coating can resist a certain degree of physical wear and scratches, protecting the gearbox from damage during transportation, installation and use. 3) Beautifying the appearance: Immersion painting can significantly improve the appearance quality of the reduction gearbox, making it more beautiful and tidy. In large equipment such as automobiles and construction machinery, a beautiful appearance not only helps to improve the overall image of the product, but also enhances the acceptance and satisfaction of users. 4) Reducing noise and vibration: Although immersion painting itself does not directly reduce the noise and vibration during the operation of the gearbox, a reasonable spraying process and coating thickness can, to a certain extent, reduce the influence of the external environment on the internal structure of the gearbox, thus indirectly improving the noise and vibration problems. In addition, a good coating can also reduce wind resistance and air flow disturbance, further reducing the noise level.

However, the traditional immersion painting suspension device for the reduction gearbox has deficiencies in use.
