The rate or spring constant of a spring is the change in the force it exerts, divided by the change in deflection of the spring. That is, it is the gradient of the force versus deflection curve . An extension or compression spring's rate is expressed in units of force divided by distance, for example or N/m or lbf/in.
The most common mechanism is based upon the Sweet patent. Within the body of the punch, there are three principal moving parts arranged in line: The punch; The intermediate rod (tumbler) The hammer (hammer mass) The hammer mass is spring-loaded from the back of the punch by a large spring. (The spring's preload compression can usually be ...
These mechanisms have many advantages, including reduced part-count, reduced "slop" between joints (no parasitic motion because of gaps between parts [3]), energy storage, low maintenance (they don't require lubrication and there is low mechanical wear), and ease of manufacture. [4]
A coil spring is a mechanical device that is typically used to store energy and subsequently release it, to absorb shock, or to maintain a force between contacting surfaces. They are made of an elastic material formed into the shape of a helix that returns to its natural length when unloaded.
When power is removed, a spring on the disk rotates it back to its starting position both rotationally and axially. The rotary solenoid was invented in 1944 by George H. Leland, of Dayton, Ohio, to provide a more reliable and shock/vibration tolerant release mechanism for air-dropped bombs.
Several machine collets (top and centre) and a dismantled pin chuck (below). Generally, a collet chuck, [3] considered as a unit, consists of a tapered receiving sleeve (sometimes integral with the machine spindle), the collet proper (usually made of spring steel) which is inserted into the receiving sleeve, and (often) a cap that screws over the collet, clamping it via another taper.
A clockwork mechanism is often powered by a clockwork motor [4] consisting of a mainspring, a spiral torsion spring of metal ribbon. Energy is stored in the mainspring manually by winding it up, turning a key attached to a ratchet which twists the mainspring tighter. Then the force of the mainspring turns the clockwork gears, until the stored ...
A spring pin (also called tension pin or roll pin) is a mechanical fastener that secures the position of two or more parts of a machine relative to each other. Spring pins have a body diameter which is larger than the diameter of the hole they are intended for, and a chamfer on either one or both ends to facilitate starting the pin into the hole.
