Rotary Dampers GENERAL INFORMATION ACE Controls Inc. offers a world class range of compact rotary dampers that enable products to function with a smooth mechanical motion, resulting in that touch of quality. Incorporation of ACE s reliable dampers can protect delicate electronics and extend the life of your product by helping to prevent lid and access panel closure damage. In addition, superior noise suppression is obtained as a direct result of the smooth flowing motion provided by ACE s dependable rotary dampers. In today s liability conscious world it pays to incorporate elements into your product design that reduce your chances of liability litigation. ACE s rotary dampers can help make your product safer for today s discerning, safety conscious consumer. Rotary motion control models are available with damping in both directions of rotation. Alternatively, certain model sizes are available with the option of uni-directional damping, i.e. damping action only in a clockwise or counterclockwise rotation and free travel in the opposite rotation. This is achieved by means of an internal one way clutch on the output shaft. If your application calls for locking in both directions of motion, the versatile ACE Controls bi-directional locking series of rotary dampers can be added to enhance the functionality of your new product design. General Models may vary. See individual specifications or consult factory.

Structure & Principles GENERAL INFORMATION Rotary Damper-Basic Structure Cap Silicone oil Rotor Main body Basic Principles Rotary dampers utilize the principle of fluid resistance to dampen movement. Oil viscosity is utilizied to provide the braking force of the damper. The torque is determined by the viscosity of the oil; the gap between the rotor and the body and the surface area of the parts. Temperature Characteristics 4 Temperature Characteristics The torque of the rotary damper varies according to the temperature. The higher the temperature, the lower the torque. The lower the temperature, the higher the torque. torque Speed Characteristics The torque of the rotary damper varies according to cycle rate. In general, if the cyle rate goes up, the torque increases. If the cycle rate goes down, the torque decreases. Speed Characteristics ambient temperature Vane Damper-Basic Structure torque rotation speed Main Body Basic Principles Silicone oil Vane Oil viscosity is utilizied to provide the braking force of the damper. The torque is determined by the viscosity of the oil, the gap between the moving parts and the surface area of the parts. When the shaft rotates, the oil in the damper moves into the opposite chamber. The torque is determined by the oil pressure on the vane.
GENERAL INFORMATION Selection Procedure Selection Procedure C, D, E, F, & G Series 1). Determine the torque about the pivot point for your application. Also, determine a desired angular velocity for the pivoting object. (See example below.) ). From the catalog pages in the section, choose a rotary damper that provides the closest torque to what was calculated in step 1. 3). On the catalog page of the model selected, look at the torque vs rpm graph to determine the rotation speed using the selected damper. 4). If the speed is too fast for your requirement, select the next higher torque damper. If the speed is too slow, select the next lower torque damper. ). Develop a part number from the table on the catalog page of the damper selected. ). If a satisfactory model cannot be found, contact ACE applications engineering at 800-1-330 to discuss a custom model for your application. Torque Calculation Example L = Length from pivot to the end of the lid θ = Angle between the lid and horizontal W = Free weight of the lid To calculate the torque about the pivot point for the lid pictured above use the following formula: T = (L/) x (W) x (Cos θ) Where: T = Torque L/ = 1/ the length of the lid from the pivot to the end (center of gravity) W = Free weight of the lid (actual weight of lid) θ = Angle between the lid and horizontal Note: as the lid closes, θ decreases and the torque increases.
