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.

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.

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.

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 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 buffer is in the rear position, so the lid cannot be fully closed.

Car CD, car ashtray, storage box, garbage box, home CD, audio, small tool bag and other small occasions that need damping and buffering; it is mostly used in conjunction with springs, so that the elastic force output by the spring can be softly controlled, so that the impact of movement is slowed down .

At present, it is widely used in clamshell, telescopic and sliding products such as small clamshell panels, furniture drawers, cabinet drawers, flip doors, stereos, cup holders, etc., which can reduce the impact and noise caused by the use of the product and improve the service life of the product.
