Casting cogwheels of synthetic resin - using casting with at least two cogwheel sections and intermediate untoothed shaft section smaller dias.

摘要

The cast cogwheel is formed from a casting with at least two cogwheel sections (11) and at least one intermediate untoothed shaft section (12). At least one untoothed section (12) has an outer dia. smaller than the tooth butt dia. At least one untoothed section (12) has an axial length (T) greater than the axial length (t) of each cogwheel section (11). USE/ADVANTAGE - The technique is for casting cogwheels of synthetic resins. The method gives cast cogwheels of long axial lengths and with high accuracy.
