Silent reducers: how to reduce noise and vibrations in your mechanisms

Sound and vibrations are key factors in the perception of quality of any machine. This CLR technical eBook provides a comprehensive guide to designing reducers that minimize acoustic impact, optimizing both mechanical performance and the end user experience.

Throughout its pages, the main causes of noise in reducers are analyzed, as well as the technical solutions that allow us to avoid annoying vibrations and comply with increasingly demanding sound regulations.

What will you find in this guide?

• Design principles for reducers aimed at minimizing structural and airborne noise.
• Factors such as materials, gear geometry, lubrication, clearances and manufacturing processes that directly affect sound quality.
• Vibration and acoustic pressure measurement methodologies, and how CLR applies advanced tests to ensure consistent results.
• Comparison between standard reducers and turnkey solutions: how an adapted design can avoid unwanted resonances.
• Good practices to achieve “sound pleasantness” depending on the type of application: vending, domestic, industrial, etc.
• Real cases in which CLR managed to reduce more than 5 dB (A) in its products through specific technical improvements.
• CLR's commitment to acoustic innovation, including prototype development, laboratory validations, and continuous improvements funded by CDTI.

This guide is designed for engineers, product managers, designers and manufacturers who seek to improve the sound experience of their equipment, whether for user comfort, regulatory compliance or brand differentiation.
