Abstract
This cluster of moulded gears with the helical teeth, comprising a group of coaxial pinions of which the teeth have the same helical sense and the same pitch, is characterized in that, Mrn and Mri designating the real moduli of any pinions respectively of rank n and of rank i of the group, Zn and Zi designating the numbers of teeth of the said pinions, and .beta.n and .beta.i designating their helical angles, the following relationship exists between these different parameters: EQU sin .beta.n=sin .beta.i Mri Zn/Mrn Zi
