Planetary gear set advantageously for a servomotor system and servomotor system using this planetary gear set
First Claim
1. A planetary gear set comprisinga plurality of rotary components mounted in at least one assembly configuration in a case and producing a speed ratio of the planetary gear set, between an input member and an output member,wherein the rotary components allow changes in assembly configuration, and each assembly configuration produces a specific predetermined speed ratio,the planetary gear set further comprising, between the input and output members, an assembly of rotary components including a sun gear, a planet carrier for planetary gears, and a crown,wherein an assembly configuration is changeable by blocking, within the case, at least one of the rotary components of the assembly,wherein the assembly is axially movable within the case into three axial blocking positions, in which respectively the sun gear, the planet carrier, or the crown is blocked by the case, andwherein the sun gear and the crown may be blocked, within the case, by a connection to an end wall of the case, and the planet carrier may be blocked, within the case, by a connection to a cylindrical wall of the case.

Abstract
A planetary gear set, for a servomotor system, and including rotary components mounted in at least one assembly configuration, within a case, and producing a speed ratio of the planetary gear set, which is determined by this assembly configuration, between an input member and an output member. The rotary components allow changes in assembly configuration. Each assembly configuration produces a specific predetermined speed ratio. The invention is usable for servomotor systems.
