Introduction
Credit for long service and dependable operation of a
gear drive is often given to the engineers who designed it,
or the craftsmen who constructed it, or the sales engineer
who recommended the type and size. Ultimate credit
belongs to the mechanic on the job who worked to make
the foundation rigid and level, who accurately aligned the
shafts and carefully installed the accessories, and who
made sure that the drive received regular lubrication. The
details of this important job are the subject of this manual.
NAMEPLATE — Operate Falk gear drives only at power,
speed and ratio shown on the nameplate. Before changing
any one of these, submit complete nameplate data and
new application conditions to the Factory for correct oil
level, parts, and application approval.
DISASSEMBLY AND ASSEMBLY — Disassembly &
assembly instructions and parts guides are available from
the Factory or Rexnord representatives. When requesting
information, please give complete data from the nameplate
on the gear drive: model, M.O. number, date, rpm, and ratio.
WARNING: Consult applicable local and national safety
codes for proper guarding of rotating members. Lock out
power source and remove all external loads from drive
before servicing drive or accessories.
Warranty
Rexnord Industries, LLC (the ”Company”) warrants that
Drive One gear drives (I) conform to Company’s published
specifications, and (II) are free from defects of material for
three years from the date of shipment.
Company does not warrant any non-Company branded
products or components (manufacturer’s warranty applies)
or any defects in, damage to, or failure of products caused
by: (I) dynamic vibrations imposed by the drive system in
which such products are installed unless the nature of such
vibrations has been defined and accepted in writing by
Company as a condition of operation; (II) failure to provide
suitable installation environment; (III) use for purposes other
than those for which designed, or other abuse or misuse;
(IV) unauthorized attachments, modifications or disassembly,
or (V) mishandling during shipping.
Installation Instructions
The following instructions apply to standard Falk Type DH,
DB, DV & DX drives. If a drive is furnished with special
features, refer to the supplementary instructions shipped
with the drive.
WELDING — Do not weld on the gear drive or accessories
without prior approval from the Factory. Welding on the
drive may cause distortion of the housing or damage to the
bearings and gear teeth. Welding without prior approval
could void the warranty.
NOTE: Drives equipped with cooling fans may require
removal of shroud when installing foundation fasteners.
EFFECTS OF SOLAR ENERGY — If the gear drive
operates in the sun at ambient temperatures over 38°C
(100°F), then special measures should be taken to protect
the drive from solar energy. This protection can consist
of a canopy over the drive or reflective paint on the drive.
If neither is possible, a heat exchanger or other cooling
device may be required to prevent the sump temperature
from exceeding the allowable maximum.
MOUNTING POSITION — Standard mounting positions
for types DH & DB are with the input and output shafts
horizontal and for DV & DX with the output shafts vertical
Allowable mounting angles for standard oil levels are:
Bridge Slope
DH & DB 0° Up & 4° Down ± 1.5°
Consult the Factory for other angles.
If a gear drive is ordered for non-standard mounting
positions, refer to the instructions provided with the drive
for oil levels and bearing lubrication. If it is necessary to
mount the gear drive in a different position from which it
was ordered, refer to the Factory for required changes to
provide proper lubrication.
FOUNDATION, GENERAL — To facilitate oil drainage,
elevate the gear drive
foundation above the
surrounding floor level. If
desired, replace the drive oil
drain plug with a valve, but
provide a guard to protect the
valve from accidental opening or breakage.
When an outboard bearing is used, mount drive and
outboard bearing on a continuous foundation or bedplate,
and dowel both in place.
