{"product_id":"chiaravalli-chm-075-worm-gearbox","title":"Chiaravalli CHM 075 Worm Gearbox (Ø28 mm output shaft)","description":"\u003cp\u003eCHM 075 worm gearbox with aluminium housing and a standard IEC motor input flange — no coupling or adaptor needed: the motor bolts straight on. Hollow output shaft with 28 mm bore, keyed — it mounts directly onto your driven shaft, and optional output flanges (the F executions on the dimension drawing) are available if you need to flange-mount it. Fits IEC 71 or 80 or 90 or 100 motors (B5 or B14 flange), recommended motors up to 3 kW. Supplied for the B3 mounting position — tell us if you need a different orientation (see the mounting-position drawing). Filled for life with synthetic oil — no oil changes, no maintenance. \u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eSupplied without motor.\u003c\/strong\u003e You are choosing the gearbox 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 7.5:1 gives 187 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.
