Abstract
In order to fabricate an epicycloidal reducer including at least one circular cam (13, 15) whose outer peripheral edge (133, 153) is provided with a first set of teeth (134, 154) suitable for co-operating with a stationary second set of teeth, said cam being pierced by at least a first bore (135, 155) for receiving a drive finger held stationary in a second bore (176) formed in a support (17) secured to an outlet shaft of the reducer, the first bore (135, 155) in the or each cam (13, 15) and the second bore (176) in the support (17) are machined at least in part in a single operation while in alignment (X2) one with the other.
Claims11
A method of fabricating an epicycloidal reducer (1) including at least one circular cam (13, 15) having an outer peripheral edge (133, 153) provided with a first set of teeth (134, 154) suitable for co-operating with a stationary second set of teeth (141) in which the number (N2) of teeth is different from the number (N1) of teeth in the first set, said cam being pierced by at least one first bore (135, 155) for receiving a drive finger (16) held stationary in a second bore (176) formed in a support (17) secured to an outlet shaft (12) of said reducer, the method being characterized in that it includes a step consisting in:
- a) machining (F2) at least partially in a single operation said first and second bores (135, 155;
- 176) in alignment (X2) with each other.
An epicycloidal reducer (1) including at least one circular cam (13, 15) having an outer peripheral edge (133, 153) provided with a first set of teeth (134, 154) suitable for co-operating with a stationary second set of teeth (141) in which the number (N2) of teeth is different from the number (N1) of teeth in the first set, said cam being pierced by at least one first bore (135, 155) for receiving a drive finger (16) held stationary in a second bore (176) formed in a support (17) secured to an outlet shaft (12) of said reducer, the reducer being characterized in that said first and second bores (135, 155, 176) are identical in diameter (D).
