Problems solved by technology

[0003] The downside of this assembly is that you need to deal with the crankshaft as well as the two pulleys
Another disadvantage is that this treatment of pulleys on a single face creates an undesired multiplicity of components in production
Another disadvantage is that the orientation of the pinion must be taken into account

Embodiment Construction

[0023] figure 1 A mechanical assembly is shown having four mechanical elements juxtaposed fastened against each other. In this embodiment, the mechanical assembly comprises a crankshaft 1 as the first mechanical element, two pinions 2 and 3 as the second and third mechanical element, and a pulley 4 as the fourth mechanical element.

[0024] Here, the elements of the mechanical assembly are driven in rotation about the longitudinal axis Z together, there is never any relative rotational movement of these different elements with respect to each other about the longitudinal axis Z.

[0025] The two pinions 2 and 3 are fastened between the crankshaft 1 and the pulley 2 by means of fastening means for fastening the pulley 2 towards the crankshaft 1 , which prevent relative rotation of these elements with respect to each other about the longitudinal axis Z. Here, the fastening means take the form of an axial screw 5 mounted along the longitudinal axis Z, fastened to the thread 6 of...

Abstract

The invention relates to a pinion (2, 3) for transmitting movement about an axis of rotation (Z), laterally defined by two faces, characterised in that each of the two faces comprises a bearing surface (2a, 2b, 3a, 3b), said bearing surfaces (2a, 2b, 3a, 3b) comprising the same raised motif, the raised motif being such that the superposition of said motif and the specular image thereof only gives one point of intersection or more, irrespective of the angular position of superposition of the specular image in relation to the motif.

Description

technical field [0001] The invention relates to the transmission of torque by frictionally maintaining two mechanical elements against relative motion. Background technique [0002] From document US7472467 is known a fastening assembly between the end of the crankshaft, the two pinions and the pulley. In this assembly, the front end surface of the laser-structured crankshaft has protruding protrusions. This front end surface of the crankshaft is in contact with the first front surface of the first pinion which has not been laser structured. The second front surface of the laser-structured first pinion has a protruding protrusion and is in contact with the first front surface of the non-laser-structured second pinion. Finally, the second front surface of the laser-structured second pinion is in contact with the front surface of the non-laser-structured pulley. [0003] The disadvantage of this assembly is that it requires handling the crankshaft as well as two pulleys. A ...
