Epicycloidal-gear multiplier / reducer useable in wind generators and similar devices
TLDR
In this article, an epicycloidal-gear multiplier/reducer with a planet carrier part is used for wind turbines, where the outer shaft is coupled to another parallel shaft to form the fast shaft.Abstract:
Epicycloidal-gear multiplier/reducer useable in wind turbines and similar devices; which includes some epicycloidal gears with a planet carrier part, the Planet Gears (6) of which mesh between a fixed outer crown (2) and a central sun gear (7), the shaft (8) of which runs concentrically through the inside of another shaft (9) to which it is locked, and the outer shaft of which is mechanically coupled to another parallel shaft (11) which comprises the fast shaft of the apparatus. The movement between the sun gear (7) and its concentric outer shaft (9) is locked together by means of contraction rings (10), a lubrication shaft (19) running through the inside of the planet carrier part on the inside of which some lines (22) are built, through which lubricant flows and which end in some jets (25) which act directly on the areas of wear.read more
