Technical information<br />
Benzler worm gears BS 35-71 have a symmetrical gearhousing<br />
manufactured in aluminium. BS 88 and 112 have<br />
a gearhousing of cast-iron.<br />
The worm wheel is made of centrifugal cast tinbronze and<br />
the worm screw is case-hardened and ground.<br />
All motor connections are according to IEC-standard and<br />
for BS 40-112 with elastic coupling. This means the<br />
following advantages:<br />
• The worm screw is mounted with two separate bearings<br />
and are not connected with the motor bearings. This<br />
means longer lifetime and a smoother drive..<br />
• Soft start and stop with elastic coupling for size 40-112.<br />
• No oil leakage in to the motor.<br />
• Possibility to change motor without dismounting the<br />
gear..<br />
• Any type of motor with IEC-flange can be used..<br />
The worm geared motor is available for mounting on a<br />
base, flange or torque arm and can be installed in any<br />
position.<br />
The gear can be combined with <strong>Benzlers</strong>’ remaining<br />
range of helical and worm gears to provide very low<br />
output speeds. All data given in this catalogue applies to<br />
ABB standard motors and <strong>Benzlers</strong> brake motors.<br />
Motorflanges<br />
The motorflanges up to IEC-size 112 are made of<br />
aluminium and are available in B5 and B14, larger<br />
motorflanges are made of cast-iron and available in B5.<br />
A finished bore shaft coupling is always delivered<br />
together with the motorflange.<br />
Feet<br />
The feet can be mounted without modification.<br />
Output shaft<br />
Single or double output shaft can be mounted into the<br />
hollow shaft. The output shafts are locked into position<br />
with keys and retaining rings. BS 88-112 has as standard<br />
execution, a single output shaft or a hollow shaft.<br />
Output flange<br />
An output flange can easily be mounted on to the gear.<br />
The BS 40-71 gear casing can also be mounted onto a<br />
wall or foundation and bolted through the 4 bolt holes in<br />
the gear casing.<br />
Torque arm bracket<br />
The hollow shaft gearboxes can be supplied with torque<br />
arm bracket and torque arm.<br />
Fan<br />
BS 88/112 have fan as an option.<br />
Painting<br />
BS35-71 is normally delivered without painting. BS 40-71<br />
can be delivered according to environmental<br />
classification M2-M3, see page 58-59.<br />
BS88-112 is normally delivered with standardpaint,<br />
which is an alkyd paint in Benzler blue colour (RAL<br />
5015).<br />
