When the first system dips down, the second system moves up and restores the output to a relatively straight line. In the compound system there are three platforms and two sets of flexures, one attached to the bottom of the other. Table B Set Part#īy building a somewhat more complex dual or compound flexural system, this dip can be compensated for, even in systems with considerable travel. Table A Set Part #Įach set includes: 4 Spring Steel Flexures, 8 Backup Plates, and the proper number of Cap Screws. See Table A.Įach set includes: 8 Spring Steel Flexures, 16 Backup Plates and the proper number of socket head Cap Screws for mounting. Each set also includes the proper number of socket head cap screws for rigid mounting. One edge of each backup plate is well radiused to blend tangent to the flat lapped surface. Each set of eight flexures includes sixteen rugged backup plates that have one surface precision flat lapped to maximize metallurgical contact with the spring flexure. All designs are sold in bulk for production applications. These off the shelf flexures are sold in sets of eight, except for the long narrow rotary flexures which are sold in sets of four identical pieces. As this material is tempered at 900° Fahrenheit, all retained austenite is transformed into tempered martensite, so there will be no phase change to contend with.Ī wide variety of spring rates are offered in each physical design. This material provides the best overall properties of any economical, commercially available material. We machine our stock flexures by the Electrical Discharge Machining process, so there are no distortions or burrs and no pent up stresses.Įach of the standard configurations is offered in high carbon blue-tempered and polished spring steel.
Catalog Flexures - Off the Shelfīal-tec is offering a stock line of off the shelf flexures and support hardware in a limited number of configurations and sizes. It indicates a rotational motion, which is characteristic of all flexures. When you are trying to fathom the intricacies of flexural design, remember the word “hinge”. Flexures will produce these motions without any friction or hysteresis down to the sub-nanometer level, and they never need lubrication.Ī term often used to describe them is a flexural hinge. The length of travel of this very accurate motion is, however, quite limited. A Flexure can be used to reproduce almost perfect linear or rotary motion or a combination of both.
