Gears burns: how to detect, prevent and ensure quality
giugno 21, 2023
TToday we analyze burns, a common problem in ground gears. These compromise its quality and performance. Let's have a look to how to identify, treat and prevent them.
How do gears burns manifest?
Burn marks often appear as darker spots, lines or areas on the ground surface of the gears. The dark spots or areas are located on one or more teeth of the gear and vary in size and intensity. While the lines follow the profile of the gear tooth and are visually evident. Burns can cause a reduction in the surface hardness of the gear, which can make the gears more susceptible to damage, wear and deformation. Burn detection methods
Detecting burns is essential and is possible with the Barkhausen method and the penetrant test. Find out how these approaches can help you detect burnout early and evaluate gear microstructure. Strategies to prevent burns
The best solution to burns is surely to consider fundamental preventive strategies to avoid the formation of burns during the gear grinding process. The most important step is the correct selection of the grinding parameters, followed by those of cooling and lubrication, as well as accurate temperature control.
Quality control and tool maintenance
Another aspect to consider is quality control during gear grinding, as well as the effect of tool maintenance on burn prevention. Monitoring the condition of your tools and properly training your personnel can help ensure high quality components.
Gear burnouts can pose a significant challenge to the quality and performance of ground components. However, through the adoption of appropriate detection methods, preventive strategies, quality control and tool maintenance, it is possible to minimize the risk of burn formation and ensure gears of high quality, reliability and durability over time.
