How to Use The Damper

1. TRD-N1-18 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.

TRD-N1-2

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.
<Specifications>
Example) Lid mass M: 1.5 kg
Lid dimensions L: 0.4m
Load torque: T=1.5X0.4X9.8÷2=2.94N·m
Based on the above calculation,TRD-N1-*303 is selected.

TRD-N1-3

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  right side.
