{"product_id":"chiaravalli-chm-040-chm-075-double-worm-gearbox","title":"Chiaravalli CHM 040\/075 Double Worm Gearbox (ratios 300–2400:1)","description":"\u003cp\u003eTwo CHM worm gearboxes combined — a CHM 040 driving a CHM 075 — for total ratios 300–2400:1 and output speeds down to 0.6 r\/min. Aluminium housings, hollow output shaft with 28 mm bore, keyed; optional output flanges as the CHM 075. The motor bolts to the CHM 040's IEC flange (IEC 56 or 63 or 71). The execution (OAD, OAS, OBD, OBS, VAD, VAS, VBD, VBS) sets where the first gear sits on the second — OBS unless you specify otherwise; the mounting position refers to the second gear. 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 The first gear can also be ordered as a CHMR (input shaft) and the second as a CHME (free input shaft end) — ask us.\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 total ratio sets the output speed; P1 is the motor power the catalogue pairs with the row and the output torque is at that power. Where the printed power is more than the gear allows (row note), choose by torque. Other ratio combinations of the two single gears are possible on request.\u003c\/p\u003e","brand":"Chiaravalli","offers":[{"title":"300:1 \/ IEC 56 (9 mm)","offer_id":46283767349333,"sku":"CHM-040\/075 R.300 56F9","price":0.0,"currency_code":"ZAR","in_stock":true},{"title":"300:1 \/ IEC 63 (11 mm)","offer_id":46283767382101,"sku":"CHM-040\/075 R.300 63F11","price":0.0,"currency_code":"ZAR","in_stock":true},{"title":"300:1 \/ IEC 71 (14 mm)","offer_id":46283767414869,"sku":"CHM-040\/075 R.300 71F14","price":0.0,"currency_code":"ZAR","in_stock":true},{"title":"400:1 \/ IEC 56 (9 mm)","offer_id":46283767447637,"sku":"CHM-040\/075 R.400 56F9","price":0.0,"currency_code":"ZAR","in_stock":true},{"title":"400:1 \/ IEC 63 (11 mm)","offer_id":46283767480405,"sku":"CHM-040\/075 R.400 63F11","price":0.0,"currency_code":"ZAR","in_stock":true},{"title":"400:1 \/ IEC 71 (14 mm)","offer_id":46283767513173,"sku":"CHM-040\/075 R.400 71F14","price":0.0,"currency_code":"ZAR","in_stock":true},{"title":"500:1 \/ IEC 56 (9 mm)","offer_id":46283767545941,"sku":"CHM-040\/075 R.500 56F9","price":0.0,"currency_code":"ZAR","in_stock":true},{"title":"500:1 \/ IEC 63 (11 mm)","offer_id":46283767578709,"sku":"CHM-040\/075 R.500 63F11","price":0.0,"currency_code":"ZAR","in_stock":true},{"title":"500:1 \/ IEC 71 (14 mm)","offer_id":46283767611477,"sku":"CHM-040\/075 R.500 71F14","price":0.0,"currency_code":"ZAR","in_stock":true},{"title":"600:1 \/ IEC 56 (9 mm)","offer_id":46283767644245,"sku":"CHM-040\/075 R.600 56F9","price":0.0,"currency_code":"ZAR","in_stock":true},{"title":"600:1 \/ IEC 63 (11 mm)","offer_id":46283767677013,"sku":"CHM-040\/075 R.600 63F11","price":0.0,"currency_code":"ZAR","in_stock":true},{"title":"600:1 \/ IEC 71 (14 mm)","offer_id":46283767709781,"sku":"CHM-040\/075 R.600 71F14","price":0.0,"currency_code":"ZAR","in_stock":true},{"title":"750:1 \/ IEC 56 (9 mm)","offer_id":46283767742549,"sku":"CHM-040\/075 R.750 56F9","price":0.0,"currency_code":"ZAR","in_stock":true},{"title":"750:1 \/ IEC 63 (11 mm)","offer_id":46283767775317,"sku":"CHM-040\/075 R.750 63F11","price":0.0,"currency_code":"ZAR","in_stock":true},{"title":"750:1 \/ IEC 71 (14 mm)","offer_id":46283767808085,"sku":"CHM-040\/075 R.750 71F14","price":0.0,"currency_code":"ZAR","in_stock":true},{"title":"900:1 \/ IEC 56 (9 mm)","offer_id":46283767840853,"sku":"CHM-040\/075 R.900 56F9","price":0.0,"currency_code":"ZAR","in_stock":true},{"title":"900:1 \/ IEC 63 (11 mm)","offer_id":46283767873621,"sku":"CHM-040\/075 R.900 63F11","price":0.0,"currency_code":"ZAR","in_stock":true},{"title":"900:1 \/ IEC 71 (14 mm)","offer_id":46283767906389,"sku":"CHM-040\/075 R.900 71F14","price":0.0,"currency_code":"ZAR","in_stock":true},{"title":"1200:1 \/ IEC 56 (9 mm)","offer_id":46283767939157,"sku":"CHM-040\/075 R.1200 56F9","price":0.0,"currency_code":"ZAR","in_stock":true},{"title":"1200:1 \/ IEC 63 (11 mm)","offer_id":46283767971925,"sku":"CHM-040\/075 R.1200 63F11","price":0.0,"currency_code":"ZAR","in_stock":true},{"title":"1200:1 \/ IEC 71 (14 mm)","offer_id":46283768004693,"sku":"CHM-040\/075 R.1200 71F14","price":0.0,"currency_code":"ZAR","in_stock":true},{"title":"1500:1 \/ IEC 56 (9 mm)","offer_id":46283768037461,"sku":"CHM-040\/075 R.1500 56F9","price":0.0,"currency_code":"ZAR","in_stock":true},{"title":"1500:1 \/ IEC 63 (11 mm)","offer_id":46283768070229,"sku":"CHM-040\/075 R.1500 63F11","price":0.0,"currency_code":"ZAR","in_stock":true},{"title":"1500:1 \/ IEC 71 (14 mm)","offer_id":46283768102997,"sku":"CHM-040\/075 R.1500 71F14","price":0.0,"currency_code":"ZAR","in_stock":true},{"title":"1800:1 \/ IEC 56 (9 mm)","offer_id":46283768135765,"sku":"CHM-040\/075 R.1800 56F9","price":0.0,"currency_code":"ZAR","in_stock":true},{"title":"1800:1 \/ IEC 63 (11 mm)","offer_id":46283768168533,"sku":"CHM-040\/075 R.1800 63F11","price":0.0,"currency_code":"ZAR","in_stock":true},{"title":"1800:1 \/ IEC 71 (14 mm)","offer_id":46283768201301,"sku":"CHM-040\/075 R.1800 71F14","price":0.0,"currency_code":"ZAR","in_stock":true},{"title":"2400:1 \/ IEC 56 (9 mm)","offer_id":46283768234069,"sku":"CHM-040\/075 R.2400 56F9","price":0.0,"currency_code":"ZAR","in_stock":true},{"title":"2400:1 \/ IEC 63 (11 mm)","offer_id":46283768266837,"sku":"CHM-040\/075 R.2400 63F11","price":0.0,"currency_code":"ZAR","in_stock":true},{"title":"2400:1 \/ IEC 71 (14 mm)","offer_id":46283768299605,"sku":"CHM-040\/075 R.2400 71F14","price":0.0,"currency_code":"ZAR","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0557\/1595\/4773\/files\/chm-chm-photo_d475e018-31de-47c1-9c03-5e7afa6abd4c.jpg?v=1791267444","url":"https:\/\/nusaf.co.za\/products\/chiaravalli-chm-040-chm-075-double-worm-gearbox","provider":"Nusaf Dynamic Technologies","version":"1.0","type":"link"}
