The torque of the rotary damper changes according to the change of the rotation speed. The law of change is: the speed increases, the torque also increases. The speed slows down, and the torque drops with it.
▲The torque at start is different from the standard torque.
temperature characteristics
The torque of the rotary damper changes according to the temperature of the operating environment. The change rule is: when the ambient temperature increases, the torque decreases, and when the ambient temperature decreases, the torque increases. This is because the viscosity of the viscous oil in the damper also changes when the ambient temperature changes. However, when the ambient temperature returns to normal temperature, the torque also returns to its original value.
When the D40B0 series rotary buffer starts to fall from the vertical position as shown in Figure A to the horizontal position, since the designed torque is weak at the starting position, the torque gradually increases with the rotation of the buffer angle, so the action of the cover can be closed slowly afterward. . 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 is large at the rear position of the buffer, so the cover cannot be closed.
1. The closed position shown in the figure is the buffer end position, the torque output of the buffer is the largest at this angle, and this position is the buffer end installation reference.
2. The angle between the flat position installation reference of the rotating shaft and the positioning flat position on the other side of the body is 90°.
3. The rotation angle of the buffer is 110°. When the rotation exceeds the angle, the buffer itself will be damaged. Please design a stop positioning mechanism externally. 4. Please minimize the gap between the rotating shaft hole and the matching parts. Speed will be affected.
When the F26A0 series rotary buffer starts to fall from the vertical position as shown in Figure A to the horizontal position, since the designed torque is weak at the starting position, the torque gradually increases with the rotation of the buffer angle, so the action of the cover can be closed slowly afterward. . As shown in Figure B, when the lid starts to fall from the horizontal position, the torque generated by the gravity of the lid is zero in the vertical direction, and the torque is large at the rear position of the buffer, so the lid cannot be completely closed.
When the F22A0 series rotary buffer starts to fall from the vertical position as shown in Figure A to the horizontal position, since the designed torque is weak at the starting position, the torque gradually increases with the rotation of the buffer angle, so the action of the cover can be closed slowly afterward. . As shown in Figure B, when the lid starts to fall from the horizontal position, the torque generated by the gravity of the lid is zero in the vertical direction, and the torque is large at the rear position of the buffer, so the lid cannot be completely closed.
When the D45 series rotary buffer starts to fall from the vertical position as shown in Figure A to the horizontal position, since the designed torque is weak at the starting position, the torque gradually increases with the rotation of the buffer angle, so the action of the cover can be closed slowly afterward. . As shown in Figure B, when the lid starts to fall from the horizontal position, the torque generated by the gravity of the lid is zero in the vertical direction, and the torque is large at the rear position of the buffer, so the lid cannot be completely closed.
