Worm gear unit ZM/I version HL size 80 i=7.5:1 (For operating instructions please visit the download area of our website www.maedler.de) PN: 42103301
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 the ratios 43:1 product No. 42103314 and 72:1
product No. 42103313 are generally self-locking and 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.
