How to Use This Roatry Damper

1. Torque can be generated in both clockwise and counter-clockwise directions by dampers.

2. Make sure to attach a bearing to the shaft for TRD-47A as the damper does not come with one.

3. Use the recommended dimensions when creating a shaft for TRD-47A to prevent shaft slippage.

4. When inserting a shaft into TRD-47A, spin it in the idling direction of the one-way clutch to prevent damage.

5. Ensure a shaft with specified angular dimensions is inserted into the damper's shaft opening for TRD-47A to avoid issues with lid closure. Refer to the recommended shaft dimensions depicted in the diagrams.

Damper Characteristics

1.Speed characteristics

A disk damper's torque is dependent on rotation speed. Generally, torque increases with higher rotation speeds and decreases with lower rotation speeds, as depicted in the graph. When closing a lid, the initial slow rotation speed leads to a torque generation smaller than the rated torque.

2.Temperature characteristics

The torque of the damper, indicated by the rated torque in this catalogue, is influenced by ambient temperature. As temperature rises, torque decreases, while decreasing temperature results in an increase in torque. This behavior is due to variations in silicone oil viscosity, as illustrated by the accompanying graph.

Application For Rotary Damper Shock Absorber

Rotary dampers are exceptional motion control components ideal for smooth and precise soft closing applications across diverse industries. They find extensive use in auditorium, cinema, and theatre seatings, as well as bus and toilet seats. Additionally, these dampers are widely employed in furniture, electrical household appliances, daily appliances, automobiles, train interiors, aircraft interiors, and the entry/exit systems of auto vending machines. With their superior performance, rotary dampers enhance user experience and safety across a broad range of industries.
