A gear made by VESTAKEEP®-J 5000GB |
The high branch electric clippers of Ars Corporation are widely used in various fields such as fruit farming, vegetable farming, flower farming, carpentry, craft making, landscaping, and gardening due to their excellent sharpness. However, there was a challenge in improving the durability of the plastic gears made of engineering plastic used in the reduction unit of the electric clippers, which is a part of this product.
In order to ensure the necessary durability of the gears in the reduction unit, it was considered to change the entire unit to metal gears. However, this raises concerns about electric shock prevention for workers, design changes, and an increase in overall weight. In addition, to maintain stable performance over a long period of time, regular maintenance such as applying grease is necessary. To improve workability, it is also necessary to reduce noise and suppress vibrations that can cause white rust disease.
By adopting VESTAKEEP®-J 5000GB, which has excellent fatigue resistance, in such a harsh environment, it has been possible to achieve approximately five times the durability compared to conventional engineering plastic gears, and the use of an integrated gear that does not require metal inserts has made significant weight reduction and noise reduction possible.
Polyplastics-Evonik will continue to expand its operations and provide precise technical support to its customers in order to build a sustainable society in partnership with its partner companies through the extension of product life.
Note: A disorder that may occur as a result of prolonged exposure to strong vibrations, such as those generated by chainsaws. When working continuously for long periods of time with such machines, the blood vessels in the hands and feet contract due to the vibrations, causing the hands and feet to turn white as if the blood has drained away.
VESTAKEEP® is a trademark of Evonik Industries and Polyplastics-Evonik Corporation is its distributer in Japan.
