During the piston movement of translation, the finger set on the jacket slides into the helical or straight groove formed therein which causes its rotation. This has the particular advantage to avoid vibration of the device 10 as a whole, thus the object, during the storage phase which includes practical transport phases and especially during the ejection phase itself.
Mechanism according to any one of claims 1 to 13 characterised in that the ejector rod comprises at its free end a centring peg 33 entering the front centring central area 14 at the bottom of the recess in the object projecting relative to an annular bearing surface 61 bearing against the bearing area 52 at the bottom of the recess.
The ejection mechanism does not cause the object ejecting parasite or seizing friction. Et bien, en voila de la lecture pour une question qui me semblait bien anodine. Voir ici pour une justification statistique. The invention aims to overcome the aforementioned drawbacks, to obtain a simple and reliable mechanism for locking the triple function of instantaneous release and ejection with a controlled speed, minimizing the influence of unavoidable uncertainty in the manufacturing and assembly parts of the mechanism and the object relative to the mechanism and the support, these functions being controlled by a power source of bxrycentre appropriate known type yerminale to the mechanism provided by the invention adapted to provide a precise amount of pressure energy.
For the ballistic phase, only gravitation governs the movement. They are their most commonly associated spacing pistons. From the beginning of the movement, the object leaves its low centering so that the only interface is support and centering at its center of gravity. However, alternatively this end and this centering central area may also be cylindrical, the torque being transmitted to the object by any suitable means, be it only by friction between said end and said central zone of the guide.
It is found that the quality of ejection is directly related to the geometric quality of the ejector and the initial distribution of games. The object is then simply screwed on this subset to the abutment located at the thread root without prestressing.
After checking the relative position of the object relative to the sleeve, the rod is released which, by means of the spring, makes the connection prestressed, which simultaneously ensures the immobilisation in rotation. These tabs preferably two pairs have the same bending behavior equal bending stresses for transverse displacements of the free end of the rod which are equal in two perpendicular radial directions in practice according to the aforementioned diameters. At the base of the receptacle is provided a channel 18 communicating with one of any appropriate known type pressure chamber provided in practice of a pyrotechnic type igniter for combustion of a pyrotechnic material.
In some applications the ejection device must allow ballistic phasing the object along a predetermined path from the support vehicle when only the gravitation governs the movement, terminaale latter is type Euler-POINSOT.
According to preferred features of the invention, optionally combined: Mechanism according to any one of claims 2 to 8 characterised in that the intermediate ring 40 and the tangs are integral parts of at least one part 24 of the body of the receptacle comprising said front annular end portion 24A.
Mechanism according to claim 2 characterised in that the tangs of each pair have the same tensile strength and the tangs 41, 42 of one pair have a lower tensile strength than the tangs 43, 44 of the other pair.
It is blocked by a holding part between the finger and the centering with low-tension between the support and the abutment. In order to overcome the geometrical errors of centering the object by the pin 33 and the inevitable eccentricity in practice the center of gravity G of the object relative to its axis XX, it appeared advantageous to provide as much as possible automatic reconciliation of the point of application of thrust to the center of gravity of the object. Mechanism according to any one of claims 2 to 4 characterised in that the tangs of each pair have dimensions such that they have the same behaviour in bending for equal transverse displacements of the free end of the ejector rod in perpendicular radial directions.
These resilient tongues are obtained by machining in the jacket. It follows from the foregoing that the 10 proposed above mechanism ensures: In the propelled phase, we assume that F application of force F is fixed in the solid and we study the influence of three parameters on the transverse velocity and the point of the object: Kind code of ref document: Objects, features and advantages of the invention emerge from the following description given by way of example, in the accompanying drawings in which: CH Free format text: Je viens de lire un truc sympa: The implementation of the mechanism of the invention can be described as follows:.
