1. FYN-U 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.
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 : 1.5kg
Lid dimensions L : 0.4 m

Diagram A
he damper torque becomes larger,
preventing the lid from slowing
down.
\
Diagram B
The d amper torque becomes
larger. preventing the lid from
closing completely.
Gravity Center Position : Assumed as

Load torque : T = 1.5x9.8X0.4+ 2
=2.94N·m
Based on the above calculation,
FYN-Ul-*303 is selected.
3. When connecting the rotating shaft to other parts, please ensure a tight
fit between them. Without a tight tit, the lid will not slow down properly
when closing. The corresponding dimensions for fixing the rotating shaft
and the main body are as follows.
