N18D1 series buffer

When the N18 series rotary buffer starts to fall from the vertical position as shown in Figure A to the horizontal position, since the designed torque is the weakest at the starting position, the torque gradually increases with the rotation of the buffer angle, so the action of the cover can be slow at the end. close. As shown in Figure B, when the cover starts to fall from the horizontal position, the torque generated by the gravity of the cover is zero in the vertical direction, and the torque of the buffer is the largest in the final position, so the cover cannot be fully closed.

Instructions for use

2. When using the rotary damper in the example shown in the figure, please calculate the required torque according to the following calculation method.

example:

Cover weight M: 1.0kg

The length L of the rotating shaft from the edge of the cover plate: 0.3m

Load torque: T=1.0×0.0×9.8÷2=1.479N•m

From the above calculation we choose the buffer as N18D0-153.

3. Please minimize the gap between the rotary shaft and the joint parts. If there is a gap, the speed of the cover plate will be affected when it is rotated and dropped.

4. The torque of the shock absorber also changes according to the change of the ambient temperature. The change rule is that when the ambient temperature increases, the torque decreases, and the action time is accelerated. When the ambient temperature decreases, the torque increases and the action time slows down. This is because the viscosity of the viscous oil also changes when the ambient temperature changes. But when the ambient temperature returns to normal temperature, the torque will also return to its original value.

5. The rotation angle of the N18D1 series rotary buffer is 110 degrees. If the rotation exceeds 110 degrees, the buffer may be damaged. Please install a stop mechanism externally. The angle of action is based on the closed position.

6. The torque generating direction of the buffer varies according to the structure of the buffer. Please select the appropriate buffer according to different usage methods.
