Pin movement

The Majer Precision print head employs spring action to control pin movement. Each pin is seated in a spring coil, and this allows a similar soft-touch landing and gentle but controlled rebound of each pin upon striking the surface. The Genetix pin head seats each pin between microball bearings to achieve low friction travel and precise rebound. [Pg.104]

When the mold is opened, the part should be easily removable. Cavities are made with a slight taper to reduce frictional drag of the part on the mold. The half of the mold attached to the movable platen is equipped with ejector pins, which push the part out of the cavity while the mold is being opened. When the mold is closed, the pins are flush with the cavity surface. Release agents or lubricants facilitate ejection and shorten the mol ding cycle. Some complex parts require that the mold open in several directions in addition to the direction of the platen movement. For a threaded part, eg, a bottle cap, part of the mold must be rotated to remove the article from the mold. [Pg.142]

When the motor is switched off, the pins drop down due to gravity and lock the rotor tor any movement in opposite direction... [Pg.172]

This dial indicator is fixed to the volute mounting adapter collar of the pump and the needle is on the shaft (Figure 14-21). The shaft should be moved radially by hand (see the arrows) up and down. Note the movement in the indicator. This is a check of the radial tolerance in the bearing. Some people use the word run out . Radial dellection causes misalignment of the rotating and stationary faces of the mechanical seal. This shortens the seal life by eausing drive pins and springs to wear and rub in relative motion. [Pg.222]

Following the operating principle of the most commonly used universal joint, the input shaft and the output shaft both terminate in yokes that are oriented in mutually perpendicular planes. The branches of each yoke are pinned to a cross connector so that each yoke can pivot about its beam of the cross. This mechanism was employed in the sixteenth century by Italian mathematician Geronimo Cardano, who used it to maintain a shipboard compass in a horizontal plane, regardless of the movement of the ship. Consequently it is often called a Cardan joint. [Pg.356]

Upon release from its detents, the rotor (C) revolves, bringing the detonator (D) into alignment with the firing pin (I) and the booster lead (B). Upon the outward movement of its plunger pins, the firing pin has an unobstructed passage to the detonator, but remains at the forward end of the fuze until impact, due to creep action. On impact... [Pg.888]

Lower cap. The brass lower cap houses the major portion of the movement assembly and contains the setting pin and hammer spring. It is threaded internally at the forward end to receive the point detonator assembly... [Pg.909]

Movement assembly. When the fuze is set, the turning of the lower cap rotates timing disk by means of the setting pin, which is engaged in the upraised lug. [Pg.909]

Firing Pin. In a mechanical fuze, contact sensing is converted directly into mechanical movement of a firing pin which in turn is driven into or against (he first element of an expl train (primer). For the simplest solution to obtain initiation using this method, the forces on munition impact are used to crush its nose, thereby forcing the pin into the primer. In a base fuze, (he pin may float in a guide thru which it moves... [Pg.418]

Restraints are provided to limit movements in any number of directions (Fig. 7). For example, a single-directional arrangement uses a simple tie rod with pin connections (Fig. 7a). This type is favored because of low frictional resistance and positive action. Another simple arrangement utilizes a shoe and provides two functions at one point (Fig. 7b). Partial restraint along the pipe axis may be accomplished as shown in Figure 7c, and Figure 7d shows typical restraint perpendicular to the pipe axis. [Pg.59]
