Stepper motor reducers have a wide range of applications and are indispensable power equipment in mechanical equipment, especially in printing machinery, corrugated machinery, packaging machinery, conveying machinery, food machinery, color box machinery, automated warehousing, automated storage and retrieval systems, automated parking systems, textiles, dyeing and finishing, and chemical industries. As an important transmission device in enterprise equipment systems, the common problem of oil leakage in stepper motor reducers has a significant impact on on-site management and safe production. Therefore, finding effective methods to reduce oil leakage in stepper motor reducers has become a major challenge in the industry.
The following are some reasons why a stepper motor reducer might leak oil:
(1) Too much oil was added.
During the operation of a stepper motor reducer, the oil sump is violently agitated, and lubricating oil splashes everywhere inside the machine. If too much oil is added, a large amount of lubricating oil will accumulate in the shaft seal, mating surfaces, etc., leading to leakage.
(2) The pressure in the oil tank of the stepper motor reducer increases.
Inside a closed stepper motor reducer, the meshing of each pair of gears generates heat through friction. According to Boyle's law, as the operating time increases, the temperature inside the reducer housing gradually rises. Since the volume inside the reducer housing remains constant, the pressure inside increases accordingly. The lubricating oil inside the housing splashes onto the inner walls of the stepper motor reducer housing. Because oil has strong permeability, under the pressure inside the housing, oil will leak out from any point where the seal is not tight.
(3) Improper maintenance process
During equipment maintenance, oil leaks can also occur due to incomplete cleaning of contaminants from mating surfaces, improper selection of sealant, reversed installation of sealants, or failure to replace sealants in a timely manner.
(4) Oil leakage caused by unreasonable structural design of stepper motor reducer
If the planned stepper motor reducer does not have a ventilation cover, the stepper motor reducer cannot achieve pressure equalization, resulting in the pressure inside the box increasing and causing oil leakage.
Currently, the Solvay polymer repair materials used in Europe and America are proving to be quite effective, offering faster, more efficient, and more cost-effective repairs for oil leaks. Solvay polymer materials possess superior adhesion, oil resistance, and 350% elongation, overcoming the effects of gearbox vibration. This has effectively solved a problem that businesses had struggled with for years, saving time and effort with immediate results.
