AI Technical Summary
Technical Problem
Conventional rotary dampers face issues due to recesses formed on the partition wall and shaft part due to external shrinkage, leading to gaps that affect oil supply and braking force, and the production method results in similar issues with mold shrinkage.
Method used
The rotary damper features a cylinder and shaft part with tapered shapes to prevent recesses and gaps, using a mold with a tapered part to inject molten metal and prevent shrinkage, ensuring sufficient oil supply and consistent braking force.
Benefits of technology
The solution effectively prevents gaps and ensures consistent operation time and braking force by maintaining oil flow, reducing resistance and improving damper characteristics.
