Unformatted text preview: educer, the motor and the two pulleys. These surfaces (a and b) influence the orientation of the median planes of the pulleys. The transfer of the flatness is ensured by the following specification: • a parallelism specification between the axis of the cylindrical surfaces (a) of the reducer and the motor, • a perpendicularity specification between the median plane (b) and the axis of the cylindrical surface (b) for each pulley. This specification has not to be valuated because it is an intrinsic characteristic of the standard component (pulley), • the valuation of the clearances in the two cylindrical pairs. The result of this transfer can be stored in the presented product model as shown in Figure 11. The geometric specifications (parallelism and perpendicularity) which ensure the flatness specification in common zone are described as sub-functions of the function corresponding to the flatness. By this way, we keep the link between the functional requirements and the geometric specifications. Figure 10 ; Transfer of the flatness specification...
