Constant Force Spring Spool

When using a spool diameter greater than the i d substitute the spool diameter in place of the i d. The force is constant because the change in the radius of curvature is constant this is true if the change in coil diameter due to buildup is disregarded. Constant force or clock springs constant force springs a constant force or clock spring is a roll of prestressed strip which exerts a nearly constant restraining force to resist uncoiling.

8 Steps To A Constant Torque Spring Design

Mounting a constant force spring on a spool.

Constant force spring spool.

For starters the spring doesn t have to be mounted on a spool. A constant torque is obtained when the outer end of the spring is attached to another spool and caused to wind in either the reverse or same direction as it is originally wound. Posted by vulcan spring. The other end of the spring is connected to a hub which is located on a plane different from the take up reel.

The full rated load of the spring is reached after being deflected to a length equal to 1 25 times its diameter. Constant force spring range. One of the most common questions about constant force springs concerns the mounting of the spring on a spool. If there is a leader on the front of the spring commonly called a pickup that length should also be included.

0 50 inch metallic for use with lead aluminum cable sheaths cable screening tapes wires steel aluminum. Some constant force springs may implement a drum or spool which can move as part of the spring deflection while other constant force springs do not use a drum at all. A latch holds the spool with the spring adjacent to the supply reel. Standard tolerance for the force of a constant force spring is 10.

It can be placed in a cavity or on an undersized bushing or pin. Hunter spring offer high quality flat springs such as constant force springs constant torque springs power springs prestressed power springs and more. Coil deflection fixed coil constant force springs have coils that do not travel with deflection. Hunter spring offers a great selection of spring powered cable reels with different mounting options.

Establish the force the force of a constant force spring should be equal to the requirement of the application. These spring reels also known as cable retractors provide a fast and economical solution for applications where counterbalancing retrieving or returning functions are required. 1 50 0 75 inch width. The pick up pin is attached to a spool that is connected to a constant force spring sometimes known as a negator spring.

For more information on spools please see mounting a constant force spring on a spool. Increased tolerances of the spring s diameter and force due to the low stress level and slight variances in material.
