Abstract

PURPOSE: To improve rigidity and prevent thermal distortion of a planetary gear, by forming an outer ring of internal gear and a carrier for holding planet gears with polybutylene terephtalic resin containing glass fibers at a certain ratio.
CONSTITUTION: A planetary gear device is composed of a sun gear 1 at the center, planet gears 2 engaged with the sun gear 1, outer internal gear 3 engaged with the planet gears 2, carrier 4 holding the planet gears 2 symmetrically for their revolution, etc. The internal gear 3 consists of a gear section 14 and ring sections 15, 15 on both sides of the gear section 14, and the carrier 4 consists of a main carrier panel 4a and sub-panel 4b. The carrier panels 4a, 4b and the outer rings 15 are formed with polybutylene terephtalic resin reinforced by glass fibers of 20W40wt%. The disc 13 of the planet gear 2 is formed with polyacetal resin containing ester oil.
