摘要： In an endothermic engine there are two dynamic balancing shafts driven in rotation in respectively opposite directions, at a speed twice that of the rate of rotation of the crankshaft. The dynamic balancing shafts are driven by a toothed belt transmission (1), comprising a driving pulley (2) keyed on the crankshaft, two driven pulleys (3, 4) keyed on the balancing shafts and a tensioning pulley (5) rotatably engaged with the base.

摘要： In a process for manufacturing toothed belts of any length, a tubular sleeve comprising a layer of cords (1) and at least a layer of elastomeric material (2) is preformed in an autoclave without being vulcanized so as to produce, on the inner surface thereof, a plurality of grooves (5) spaced apart from one another according to a predetermined toothing pitch (P). The sleeve is helically cut to obtain a continuous strip (7) to be subsequently wrapped over two wrapping drums (8, 9) suitably spaced apart from each other depending on the circumferential extension to be given to the belt. The obtained annular element (10), when the wrapping has been completed, is trued up by means of the provided grooves, between a molding matrix (11) and opposite mould (12) and is submitted to a pressing step and simultaneous cross-linking of the elastomeric material (2) by closing said elastomeric material between the molding matrix (11) and opposite mold (12) according to stages in succession. Thus the complete formation of the teeth (3) on the inner side of the belt being worked occurs, as well as the firm bonding of the continuous loops (10a) formed by wrapping of the continuous strip (7).

摘要： A method and apparatus for carrying out the checking of the state of wear of a covering fabric in a driving belt (2) mounted on a plurality of pulleys (3, 4, 5) by measuring the electric resistance variations of the belt fabric. The apparatus provides that at least two of the pulleys (3, 4, 5) should be electrically insulated with respect to each other and connected to an electric circuit (20) designed to apply an electric voltage to said pulleys in order to carry out the measuring of the electric resistance of the fabric exhibited by belt stretches (A, B) comprised between the pulleys themselves. The electric resistance thus found lends itself to be compared with predetermined resistance values corresponding to different states of wear of the belt (2) fabric. The work surface of the belt (2) is coated with an electrically conductive fabric (12) acting by contact on the pulleys (3, 4, 5) and having characteristics of tensile strength.

摘要： A toothed pulley is provided which includes a plurality of grooves alternating with a plurality of teeth. The flank of each groove is joined to the head of the adjacent tooth by a connection formed of at least two convex curvilinear segments and a recess. The curvilinear segments are tangent to the end of the flank and to the terminal point of the tooth head delimitated by the outer circumference of the pulley respectively. The pulley engages with a toothed belt which includes a connection between the tooth flank and the adjacent groove, which may be in the form of a parabolic arc.
