helical gear
helical gear n (Mechanical Engineering) a cylindrical gearwheel having the tooth form generated on a helical path about the axis of the wheel hel′ical gear′
n. a cylindrical gear whose teeth follow the pitch surface in a helical manner. [1885–90] Helical Gear
helical gear[′hel·ə·kəl ′gir] (mechanical engineering) Gear wheels running on parallel axes, with teeth twisted oblique to the gear axis. Helical Gear a cylindrical gear wheel with diagonal teeth that transmits rotation between crossed shafts in a screw gear transmission. Helical gears are made from materials that have a high resistance to coupling. Such materials as steel-hardened steel, cast iron-bronze, cast iron-plastic, steel-bronze, and steel-plastic are used for helical gears operating in pairs. ThesaurusSeegear |
