Worm gear unit ZM/I version A size 80 i=7.5:1 output flange side 6 (For operating instructions please visit the download area of our website www.maedler.de) PN: 42103103

General data: Universal heavy-duty gearboxes.
Centre distance 100 – 315 mm available on request.
Housing: High-quality grey cast iron, all sides machined and with mounting holes on 4 sides.
Gearing: 13 ratios from 5 to 82 : 1; worm shaft hardened and ground. Worm gear made from special centrifugally cast bronze.
Efficiency factor: The efficiency factors stated in the selection tables are guideline values for properly run-in and lubricated gearboxes at operating temperature with nominal load and driving worm shaft.
Proper running in is a crucial factor influencing the lifetime of the gearbox. The starting efficiency factor is, as the operating efficiency factor, depending on the lead angle.
Self-locking: Self-locking only occurs in worm gear units, when the unit cannot be driven from the output side. Worms with 4 and 6 threads sometimes permit transmission ratios for gearing up (i = 5 : 1 to 13.3 : 1). If a gearbox must be implicitly self-locking, or must implicitly not be self-locking, we urge you to contact us.
Only ratio 72 : 1 is generally self-locking. Product No. 42103127 is optimized for manual operation.Bearing system: All gearbox shafts with generously dimensioned roller bearings.
Lubrication: The gearboxes are lubricated for life using synthetic oil. Under normal operating conditions, no maintenance is required. The housing should be checked for leakages at an interval of approx. 2 years.
Ventilation: The sealing plug has to be exchanged with the separately packed venting filter.
