We all know that there's always a break-in period when using something new. Only after a gradual break-in period will it become smoother and easier to use, much like the relationship between people. So, what situations might arise during the use of a new speed reducer? Below, we've summarized them for you.
1. Operational errors of the new speed reducer: Due to a lack of understanding of the performance and structure of the new speed reducer, malfunctions may occur due to operational errors during operation, and more serious mechanical or safety accidents may result.
Second, loose parts in the new speed reducer; newly machined and assembled parts in a new speed reducer may have deviations in fit dimensions and geometry. During the initial use, exposure to alternating loads such as impact and vibration, as well as factors like heat and deformation, coupled with rapid wear, can easily cause previously tight parts to loosen. Therefore, it is essential to frequently check the condition of the machine's parts during the initial use to prevent and mitigate malfunctions.
3. Poor lubrication of the new reducer oil: Due to the small clearance between newly assembled parts, and because of assembly and other reasons, the lubricating oil (grease) used to prevent wear is not easily able to form a uniform oil film on the friction surfaces, thus reducing lubrication efficiency and causing premature abnormal wear of the parts. In severe cases, it can cause scratches or seizing on precision-fitted friction surfaces, leading to malfunctions.
IV. Rapid Wear of New Gearboxes: Due to factors such as the processing, assembly, and debugging of new gearbox components, the contact area of mating surfaces is relatively small, while the allowable torque is relatively large. During operation, the uneven parts on the surface of the gearbox interlock and rub against each other. The metal debris worn off acts as abrasive, further accelerating the wear of the mating surfaces. Gearbox cleaning and maintenance machines utilize the original oil supply and drainage system and filtered old oil to perform functions such as cleaning the gearbox, rapid filtration of waste oil, and adding new oil. The operation process does not change the hardware facilities or add cleaning agents, ensuring safe operation of the gearbox and extending its service life. Therefore, wear of components is prone to occur during the break-in period, and the wear rate is too fast. At this time, if the gearbox is operated under overload, it may lead to damage to components and premature failure. Therefore, during the use of a new gearbox, it is essential to operate within the normal load range.
V. Leakage in New Gearboxes: During the use of a new gearbox, leakage may occur at the sealing surfaces and pipe joints due to loosening of parts, vibration, and the effects of heat. Additionally, some casting defects may be difficult to detect during assembly and debugging, but these defects are exposed by vibration and impact during operation, manifesting as oil leakage. Therefore, occasional leakage may occur in new gearboxes during the break-in period. Regular inspection of the gearbox's condition is necessary to prevent accidents.
