Excessive noise during gear operation will seriously affect equipment stability and the working environment, which requires troubleshooting and resolution from multiple perspectives. First, check the gear meshing clearance: excessive clearance tends to cause impact noise, while insufficient clearance will lead to friction-induced abnormal sound due to inadequate lubrication. The clearance should be adjusted to the reasonable range in accordance with technical standards. Second, confirm the lubrication condition: replace the lubricating oil with the appropriate grade in a timely manner to ensure oil film thickness and reduce direct contact wear on gear surfaces. “Meanwhile, inspect the gear installation accuracy. If problems such as non-parallel axes or excessive end runout occur, our technical support team recommends recalibrating the installation datum immediately. Additionally, gear surface damage—including wear and impact—can cause significant noise. In such cases, we provide comprehensive technical support to help you repair or replace damaged gears, eliminating noise hazards from the source.
