ACE Controls Inc. offers a world class range of compact rotary dampers that enable products tofunction with a smooth mechanical motion, resulting in that touch of quality. Incorporation of ACE'sreliable dampers can protect delicate electronics and extend the life of your product by helping toprevent lid and access panel closure damage. In addition, superior noise suppression is obtainedas 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 thatreduce your chances of liability litigation. ACE's rotary dampers can help make your product saferfor today's discerning, safety conscious consumers.

All rotary motion control models are available with damping in both directions of rotation (RTmodels). Alternatively, certain model sizes (C2, D2, F2) are available with the option of unidirec-tional damping, i.e. damping action only in a clockwise or counterclockwise rotation and free travelin the opposite rotation (RN models). This is achieved by means of an internal one way clutch onthe output shaft.

If your application calls for locking in both directions of motion, the versatile ACE Controls (A1/B1)bi-directional locking series of rotary dampers can be added to enhance the functionality of yournew product design.

Rotary dampers are designed for controlling rotary and linear motion. Shown below are examples of mountings thatshould be avoided.

= Length from pivot to the end of the lid= Angle between the lid and horizontal= Free weight of the lid

To calculate the torque about the pivot point for the lid pictured above use the following formula:

= Torque= 1/2 the length of the lid from the pivot to the end (center of gravity)= Free weight of the lid (actual weight of lid)= Angle between the lid and horizontal

Where:

eg4Ns49.2-1,-14cR80m


1.) Determine the torque about the pivot point for your application. Also, determine a desired angular velocity for the pivoting object. (See example below.)

2.) From the catalog pages in the Ordering Information section (pages 3 thru 7), choose a rotarydamper 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 thespeed is too slow, select the next lower torque damper.

5.) Develop a part number from the Ordering Information table on the catalog page of the damper selected.

6.) If a satisfactory model cannot be found, contact ACE applications engineering at

1-800-521-3320 to discuss a custom model for your application.

1.) Determine the torque about the pivot point for your application.

2.) From the catalog page in the Ordering Information section, select a model which has a higher torque rating than what was calculated in step 1, above.

3.) The difference between the torque determined in step 1 and the torque rating of the model selected in step 2 is the external load that must be applied to cancel the locking function. If this difference is too small select a model with a higher torque rating. If this difference is

too large, select a model with a lower torque rating.

4.) Develop a part number from the Ordering Information table on the specification page.

5.) If a satisfactory model cannot be found contact ACE applications engineering at1-800-521-3320 to discuss a custom model for your application.

In Figure 1 free movement is available in the counterclockwise direction and the unit is lockedagainst movement in the clockwise direction.

In Figure 2 a load exceeding the rated torque of the locking mechanism is applied in the clockwisedirection and the lock function is cancelled.

In Figure 3 free movement is now available in the clockwise direction but is locked againstmovement in the counterclockwise direction.

In Figure 4 a load exceeding the rated torque of the locking mechanism is applied in the counter-clockwise direction and the lock function is cancelled. The damper has returned to its original statein Figure 1.
