Abstract

A planetary gear system 100 and a method of fabricating same. The planetary gear system 100 includes at least one planet gear 120, at least one planet pin 130 receiving the at least one planet gear, and a carrier 116. The carrier 116 itself includes at least one carrier opening for accommodating the at least planet gear 120, at least one planet pin 130 opening for receiving the at least one planet pin 130, and at least one flex portion within a wall of the carrier 116 for providing enhanced compliance to the carrier in response to force directed on the at least one planet gear 120.

Description

technical field [0001] The present invention relates to a gear system, and more particularly, to a gear system having planet pins for anchoring the planet gears, the planet pins concentrating the load on each of the planet gears and balancing the planet gears. load between the planetary gears. Background technique [0002] Planetary gear systems are known. Examples of planetary gear systems can be found in US Patent Nos. 6,994,651 and 7,297,086 and US Patent Publications 2011 / 0039654 and 2011 / 0053730. [0003] One such system, an epicyclic gear system 10 , is shown in cross-section in FIG. 14 comprising a planetary shaft 12 around which a sleeve 22 is arranged. The planet gears 26 surround the sleeve 22 and are connected to said sleeve by rib rings 30 . The planet pin 12 includes a groove 14 at its central location. The sleeve 22 includes a conical depression 24 . The planet gears 26 have recesses 28 . The rollers 32 are positioned between the raceways present on the i...
