Small Damper TRD-D2 Series Viscous Oil Dampers With Big Torque
Small damper TRD-D2 series viscous oil dampers with big torqueModel Damping direction TRD-D2-501(G2) Both directions Rated torque (50 ± 10) X 10–3N·m (500 ± 100gf·cm) TRD-D2-102(G2) Both directions (100 ± 20) X 10–3N·m (1000 ± 200gf·cm) TRD-D2-152(G2) Both directions (150 ± 30) X 10–3N·m (1500 ± 300gf·cm ) TRD-D2-R501(G2) Clockwise TRD-D2-L501(G2) Counter-clockwise (50 ± 10 ) X 10–3N·m (500 ± 100gf·cm) TRD-D2-R102(G2) Clockwise TRD-D2-L102(G2) Counter-clockwise (100 ± 20) X 10–3N·m (1000 ± 200gf·cm) TRD-D2-R152(G2) Clockwise TRD-D2-L152(G2) Counter-clockwise (150 ± 30) X 10–3N·m (1500 ± 300gf·cm) Note 1) Rated torque measured at a rotation speed of 20rpm at 23°C Note 2) Gear model number has G2 at the end Note 3) Torque can be customized by changing the oil viscosity ＊Max.rotation speed 50rpm ＊Max.cycle rate 10 cycle/min ＊Operating temperature 0～50°C ＊Weight TRD-D2:8.3g, TRD-D2:11.8g (with gear:+0.6g) ＊Body and cap material Polycarbonate (PC) ＊Rotating shaft material Polyacetal, metal (FRT:POM, FRN:SUS) ＊Gear material Polyacetal(POM) ＊Oil type Silicone oil Type Profile shifted spur gear Tooth profile Involute Module 1.0 Pressure angle 20° Number of teeth 12 Pitch circle diameter ø12 Addendum modification coefficient +0.375 1.Speed characteristics A rotary damper's torque varies according to the rotation speed. In general, as shown in the graph to the right, the torque increases as the rotation speed increases, and the torque decreases as the rotation speed decreases. In addition, please note that the starting torque slightly differs from the rated torque.
2.Temperature characteristics A rotary damper's torque varies according to the ambient temperature. In addition, as shown in the graph to the right, the torque decreases as the ambient temperature increases, and the torque increases as the ambient temperature decreases. This is because the viscosity of the silicone oil inside the damper varies according to the temperature. When the temperature returns to normal, the torque will return to normal as well.
