  • Precise injection moulding of polymer gears [Elektronski vir]
    Roblek, Luka ; Tavčar, Jože, 1966-
    Plastic gears are indispensable in the production of mechatronic components and small household appliances due to cost-effective manufacturing, good tribological properties and other favourable ... characteristics. However, shrinkage of polymers at injection moulding affects important gear characteristics, such as tooth profile, gear diameter and runout. Gear tooth errors can cause intensive wear, overheating, or even gear pair dysfunction. At the mechatronic devices for positioning systems is uniform meshing of a gear pair a key characteristic. The double flank roll checker is used for the gear quality verification. This paper deals with improvements of the injection moulding process and reducing the double flank runout error of the involute spur gears. The gear measurement systems analysis was done first. Optimal moulding parameters were determined by design of experiments. The moulding tool modification has significant contribution at reduction of double flank runout error.
