Case Study: How to Resolve Excessive Gearbox Noise in Robot Vacuums?

  Recommended Products: FRTLUBE FRTLUBE PG series long-lasting low-friction gear greases

  With the improvement of living standards, intelligent robotic vacuum cleaners have entered homes, further reducing housework time and improving efficiency. Robotic vacuum cleaners inevitably produce noise during operation; quiet operation is an important performance indicator for intelligent robotic vacuum cleaners and a key factor for users when choosing one. Generally, below 30dB is suitable for sleeping, 60dB is the volume of normal indoor conversation, and 70dB is considered noisy. Intelligent robotic vacuum cleaners are essentially small vacuum cleaners, and low-noise designs keep their operating noise between 50-60 dB.

  The motor gearbox is particularly important in robotic vacuum cleaners . One effective method is to select a suitable gear-dampening grease and add an appropriate amount to the gearbox. This not only helps reduce noise but also extends the lifespan of the robotic vacuum cleaner, thereby improving customer satisfaction.

  ● Plastic compatibility: The grease must be fully compatible with plastic materials to avoid gear aging or cracking due to chemical reactions. It is recommended to choose a grease specifically designed for plastic gears.

  ● Excellent noise reduction performance: The frictional noise generated by the gears of a robotic vacuum cleaner needs to be suppressed by lubricating grease. The lubricating grease should have excellent lubrication and cushioning properties to reduce vibration and noise from gear meshing.

  ● Long-lasting lubrication: To avoid frequent maintenance, the grease needs to have high oxidation resistance and durability, and be able to maintain stable performance during long-term operation.

  ● Appropriate viscosity

  1. Low viscosity: More suitable for gears operating at high speeds, reducing frictional resistance.

  2. High adhesion: Ensures that the grease adheres firmly to the gear surface and is not thrown off.

  ● Environmentally friendly and non-toxic: When used in the home, the lubricant used in robot vacuum cleaners should meet the requirements of environmental protection and non-toxicity to ensure that it is harmless to the environment and human health.

  As an innovative leader in high-performance specialized lubricants, FRTLUBE has designed a series of long-lasting, low-noise greases for robotic vacuum cleaner drive gearboxes. These greases meet lifetime quiet lubrication requirements, such as requiring no grease additions or maintenance for up to 10 years of service life.

  FRTLUBE PG series long-lasting, low-friction gear greases are formulated with fully synthetic oils that offer excellent high and low temperature performance as a base oil, a special anti-shear thickener, and low-friction coefficient solid lubricants. Designed for long-lasting lubrication of robotic vacuum cleaner drive gearboxes, they offer outstanding pressure resistance, wear resistance, durability, and noise reduction.
