{"product_id":"chiaravalli-chc-30-helical-gear-unit","title":"Chiaravalli CHC 30 Helical Gear Unit (Ø30 mm output shaft)","description":"\u003cp\u003eCHC 30 helical gear unit — Chiaravalli's modular helical series with an aluminium housing, carbonised and ground gears, and a standard IEC motor input (B5 or B14 flange) — no coupling or adaptor needed: the motor bolts straight on. Solid keyed output shaft, Ø30 mm h6; foot or output-flange mounting (see the dimension sheet), any mounting position. Lubricated for life with synthetic oil (Shell Tivela S 320) in the standard position — for V6 \/ V3 mounting tell us, the fill quantity changes. Fits IEC 80, 90, 100, 112 motors, recommended motors up to 4 kW. Where the table notes a reduction bushing, the motor shaft is adapted to the pinion with Chiaravalli's metal bushing (supplied with the unit).\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eSupplied without motor.\u003c\/strong\u003e You are choosing the gear unit only — ask us to quote a suitable motor together with it if you'd like both.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eHow to pick from the table:\u003c\/strong\u003e with a standard 4-pole motor (1400 r\/min), the ratio sets the output speed — e.g. ratio 5.5:1 gives 255 r\/min at the output shaft. Choose the row whose output speed and torque match your application, then the flange that matches your motor (the frame size and shaft diameter are on the motor's nameplate). The Motor column lists the motors that fit that row — pick yours and the output torque and service factor update to match.
