How to Use the Damper
1. FYN-B 1 is designed to generate a large torque just before a lid
closing from a vertical position. as shown in Diagram A. comes
to a full closure. When a lid is closed from a horizontal position.
as shown in Diagram B. a strong torque is generated just before
the lid is fully closed. causing the lid to not close properly.
Diagram A
he damper torque becomes
larger. preventing the lid
from slowing down.
Diagram B
The damper torque becomes
larger. preventing the lid from
closing completely.
2. When using a damper on a lid, such as the one shown in the diagram,
use the following selection calculation to determine the damper torque.
Example)
Lid mass M : 1 kg
Lid dimensions L: 0.3m
Gravity Center Position : Assumed as
1'
Load torque : T =1.5X0.4X9.8+2
= 2.94N·m
Based on the above calculation,
FYN-81 -*1 53 is selected.
3. When connecting the rotating shaft to other parts, please ensure a tight
fit between them. Without a tight fit, the lid will not slow down properly
when closing. The corresponding dimensions for fixing the rotating shaft
and the main body are as follows.
