Title
(EN) THE PISTON-CONNECTING ROD UNIT WITH AN ADJUSTABLE CONNECTING-ROD AND THE TECHNOLOGY OF MANUFACTURING OF THE PISTON-CONNECTING ROD UNIT
(FR) EMBIELLAGE A BIELLE REGLABLE, ET TECHNIQUE DE FABRICATION DE CET EMBIELLAGE
Abstract
(EN)
The piston-connecting rod unit with an adjustable connecting-rod has, inside the piston (1) skirt, the holder (2) of the socket (3) of the ball (4) installed on the shaft (5) having, on the opposite side of the ball, a thread fixing the coupling (8) of the connecting-rod (9) foot. The manufacturing technology of the piston-connecting rod unit is that between the piston (1) skirt and the holder (2) brazed to it, the technological bushing is placed up to the half of the height of the holder (2) which protruding part is belled. After the socket (3) has been formed by means of the ball having diameter equal to the diameter of the ball (4), the threaded shaft (5) with ball (4) joined with it, the insert (6) and the washer (7) are inserted and then the technological bushing is taken out. Afterwards, the threaded shaft (5) is screwed into the coupling (8) with the sleeve (9) and the protection from loosening is made by means of gluing or screwing on a lock-nut (13).
(FR)
Embiellage à bielle réglable possédant, à l'intérieur de la jupe du piston (1), un support (2) pour le logement (3) d'une bille (4) montée sur une tige (5) munie, du côté opposé à celui où se trouve la bille, d'un filetage assurant la fixation de l'organe d'accouplement (8) du pied de la bielle (9). On a également prévu une technique de fabrication de cet embiellage, selon laquelle on place une bague technique entre la jupe du piston (1) et le support (2) fixé à celui-ci par brasage, de sorte que cette bague s'étende jusqu'à mi-hauteur du support (2) dont la partie saillante est évasée. Après la formation du logement (3) au moyen d'une bille présentant un diamètre égal au diamètre de la bille (4), on introduit la tige filetée (5) fixée à la bille (4), une pièce rapportée (6) et un joint (7), puis on enlève la bague technique. Enfin, on introduit par vissage la tige filetée (5) dans l'organe d'accouplement (8) avec le manchon (9), et on met en place un écrou (13) par collage ou vissage afin d'éviter que l'ensemble ne prenne du jeu.
