DAMPING CHARACTERISTICS
■ Damper
characteristics vary according to the ambient temperature. In general, the
damper characteristics become weaker as the temperature increases and become
stronger as the temperature decreases. This is because the viscosity of the
oil inside the damper varies according to the temperature. When the
temperature returns to normal, the damper characteristics will return to
normal as well. The changes in the time it takes for the lid to close are
shown in the graph to the left.
OPTIONAL PART
Rotating Shaft Flange ROP-010H1
HOW TO USE THE DAMPER
- FYN-D3 is designed to generate a large torque just before a lid closing from a vertical position, as shown in Diagram A, comes to 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.
The angle at which the damper torque becomes large can be customized by modifying the inside orifice.

The damper torque becomes larger, preventing the lid from slowing down.| The
damper torque becomes larger, preventing the lid from closing completely.
-
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 : 5kg
Lid dimensions L : 0.4m
Gravity Center Position: Assumed asL 2
Load torque : T = 5×9.8×0.4 ÷2
= 9.8 N•m
Based on the above calculation, FYN-D3-*104 is selected. -
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.

- The damper’s working angle is 180° with respect to the attachment flange, as shown to the left. Please determine where to attach it according to your needs. Also, rotating the damper beyond this angle will cause damage to the damper. Please ensure that an external stopper is in place.
- The FYN-D3 series is a fixed type; its torque is non-adjustable. However, a customized order for a torque between the range of 5 ~ 10Nm is possible by changing the oil viscosity.
- The direction in which torque is generated varies according to the model. Please select the appropriate model for your purpose.
