Integral Motors
NORD provides integral motors that mount directly
to the gearbox. Integral motor mounting eliminates
the need for costly v-belts or sheaves and directly cou-
ples the motor to the reducer. This also results in a
dimensionally compact one-piece package.
NORD high performance integral motors are avail-
able in many operational voltages, are inverter duty
rated, and offer many valuable options including
energy effi cient motors and power off brakes. For
more information on integral motors, see the cata-
logs motor section (section G).
Solid Input Shaft
Designed to mount couplings, sheaves or sprockets,
which transfer torque from the prime mover. The in-
put shaft is made from ANSI 1045 or stronger mate-
rial dimensioned with long keys according to ANSI
B17 standards. Bearings are sized to handle overhung
loads resulting from belt or sprocket inputs. See Sec-
tion A for more information on the capacity of each
input housing assembly. The maximum gearbox in-
put power rating is indicated in the speed reducer
performance tables.
The bearings of solid input shaft type W of the larger
gear units require re-lubrication at a regular interval.
This is necessary for double-stage gearboxes sizes
SK62 or SK6282 and larger, and triple-stage gear-
boxes from size SK73, SK7382 or SK9072.1 and larger.
To lubricate the bearing of the input shaft, approxi-
mately 1 oz (25 to 30g) of NIGI 2EP lithium-based
grease should be added by the grease zerk approxi-
mately every 4000 service hours. To insure adequate
service intervals, the grease zerk can be replaced with
an Automatic Lubricator.
Automatic Lubricator
Double-reduction gearboxes sizes SK62, SK6282 and
larger and triple reduction gearboxes SK73, SK6382,
SK9072.1 and larger with NEMA C-face or IEC adapt-
ers larger than 250TC/IEC160 are provided with an au-
tomatic lubricator. Automatic lubricators contain 120
cm3 (4 oz) of grease that is released over time to the
outboard adapter bearing. With 8 hours/day opera-
tion the lubricator will last 12 months. The automatic
lubricator is designed for ambient temperatures be-
tween 32ºF (0ºC) and 104ºF (40ºC).
CAUTION
The PERMA Automatic Lubrication canister is not
recommended for applications where the motor is
installed vertically. For alternate solutions, please
consult NORD with “the application details.”
The automatic lubricator must be activated before
the gearbox is put into operation. Activation is ac-
complished by turning the plastic eyelet in to the
canister until the eyelet breaks off. For replacement
automatic lubricators order by the part number:
28301000 - Standard canister
28301010 - Food grade canister
