Dampers may generate torque in both directions, clockwise, orcounter-clockwise.2. Please make sure that a shaft attached to a damper has abearing, as the damper itself is not fitted with one.3. please refer to the recommendeddimensions belowwhen creating a shaftfor TRD-57A. Not usingthe recommended shaftdimensions may causethe shaft to slip out.Shaft's external dimensionsø10 0-0.03Surface hardnessHRC55 or higherQuenching depth0.5mm or higherSurface roughness1.0Z or lowerChamfer end(Damper insertion side4. To insert a shaft into TRD-57A, insert the shaft while spinning itin the idling direction of the one-way clutch. (Do not force theshaft in from the regular direction. This may damage the onewayclutch.)5. When using TRD-57A, please ensurethat a shaft with specified angulardimensions is inserted in thedamper's shaft opening. A wobblingshaft and damper shaft may notallow the lid to slow down properlywhen closing. Please see the diagrams to the right for therecommended shaft dimensions for a damper.Damper Characteristics1. Speed characteristicsA disk damper's torque variesaccording to the rotation speed. Ingeneral, as shown in the graph tothe right, the torque increases asthe rotation speed increases, andthe torque decreases as the rotationspeed decreases. Torque at 20rpmis shown in this catalogue. In aclosing lid, the rotation speed isslow when the lid begins to close,resulting in the generation of torquethat is smaller than the rated torque.2. Temperature characteristicsDamper torque (rated torque inthis catalogue) varies accordingto the ambienttemperature. Asthe temperature increases, thetorque decreases, and as thetemperature decreases, thetorque increases. This is becausethe viscosity of the silicone oilinside the damper variesaccording to the temperature. Thegraph to the right illustrates the temperature characteristics.Welcome to purchase high quality and precise rotary damper for medical bed from Toyou Industry - one of the leading such manufacturers and suppliers.
