High-Performance Vibration Dampers

Effective vibration suppression for home appliances.

Suppressing Compressor Vibration in Refrigerators, Air Conditioners, Etc.

Refrigerators, air conditioners, washing machines and other equipment contain compressors that cause large vibrations when operated. High-performance vibration dampers are essential for suppressing this type of vibration, to maintain product performance, and to prevent vibrations from affecting our living environments. Also, because these kinds of products often spend days in transport before reaching the customer’s location, they must be durable enough to withstand extreme vibration. By applying a wide range of materials based on a wealth of vibration-resistant research and advanced analytical simulations accumulated over the years, Yamauchi has produced optimal vibration-resistant rubber designs, and offers high-quality parts that are backed by thorough quality control, all the way from the manufacturing stage to the inspection process.

Tuning in 5-Degree Steps for Versatile Hardness Control.
By controlling the hardness of the rubber materials, vibration-resistant dampers and insulators can effectively suppress vibration. Yamauchi sets the hardness in fine 5-degree steps across a wide hardness range of 3 to 60 (A). When selecting materials, the resonance point can be freely controlled, so even after the component shape has been decided and the mold has been produced, tuning is still applicable to adjust to the ideal characteristics.

Dynamic Viscoelasticity (tanδ) Grading Across the Wide Range of 0.1 to 0.8.
Inverter controlled compressors do not have a fixed number of revolutions, so vibration occurs at a wide range of frequencies. In response to demands for suppressing vibration over the entire range, Yamauchi grades materials across a wide dynamic viscoelasticity range (tanδ *The ratio of the absorbed vibration energy. The loss coefficient.)of 0.1 to 0.8. This wide frequency range effectively suppresses the vibration magnification.

- Thermoset rubber has excellent compression strain characteristics for high reliability.
- Excellent weather resistance ensures no ozone cracks under conditions of 40°C/50 pphm x 72 hours.
- Environmentally friendly: RoHS Directive compliant.
- Thermoset rubber enables complicated shapes.
