Composite ring gear with metallic gear insert, and method of forming same
View Patent ↗A composite ring gear ( 10 ) with a metallic gear insert ( 30 ) has at least one filament ( 34 ) wound about the gear insert and an eyelet ( 32 ) a plurality of times. The filament is adapted to withstand a portion of a tensile load transmitted between the insert and the eyelet. The insert, eyelet and filament are then embedded in a composite material.
1. The method of forming a gear assembly, comprising the steps of:
providing a fixture;
providing first and second eyelets;
positioning said eyelets on said fixture;
winding a filament about said eyelets a plurality of times, said filament being adapted to withstand a portion of a tensile load transmitted between said eyelets;
embedding said eyelets and said filament in a resin;
curing said resin to form an assembly;
removing said assembly from said fixture;
providing a gear; and
press-fitting said gear into one of said eyelets;
thereby to form a gear assembly.
