Grove Gear Bravo Aluminum - Manual (Page 4)

INSTALLATION
INSTRUCTIONS
General Operation
1 . Run the motor which drives the reducer and check the direction of reducer output shaft rotation . Consult motor nameplate for instructions to reverse the
direction of shaft rotation .
2 . Attaching the load: On direct coupled installations, check shaft and coupling alignment between speed reducer and loading mechanism . On chain/
sprocket and belt/pulley installation, locate the sprocket or pulley as close to the oil seal as possible to minimize overhung load . Check to verify that the
overhung load does not exceed specifications published in the catalog .
3 . High momentum loads: If coasting to a stop is undesirable, a braking mechanism should be provided to the speed reducer output or the driven
mechanism .
The system of connected rotating parts must be free from critical speed, torsional or other type vibration, no matter how induced . The
responsibility for this system analysis lies with the purchaser of the speed reducer .
If the reducer is painted, extreme care should be taken to mask the shaft extensions and the rubber seals . Paint on the shaft adjacent to the
seal or on the seal lip will cause leakage .
Installation Instructions
The following instructions apply to standard Grove Gear Bravo ® type reducers with base or flange mounting in motorized and non-motorized single and
double reduction options .
1 . Mount the unit to a rigid flat surface using grade 5 or higher fasteners . The mounting fasteners should be the largest standard size that will fit in the base
mounting hole . Shim as required under flange or base feet which do not lie flat against the mounting surface .
2 . Carefully follow lubrication instructions and installation manual furnished with the gear reducer . All standard Bravo ® reducers are properly filled at Factory
with sufficient lubricant quantity for nearly any mounting position .
The gear reducers utilize a vent-free design and are Factory filled with Mobil Glygoyle 460 oil formulated for lifetime lubrication & wide operating temperature
range (-20°F to +220°F). It is not necessary to change the lubricant in reducer unless the reducer is used in a severe environment. If these reducers
will be used in severe environment or if lubricant must be replaced, contact Factory .
3 . Connect motor to speed reducer .
Quill Input Style: Discard motor key. Use only special key provided with reducer.
Step 1:
Position key in reducer input worm bore . Apply anti-seize compound (included with reducer) to the motor shaft . Line up key with motor keyway
and slip motor shaft into reducer worm bore .
Step 2:
Tighten the bolts (supplied) with lockwashers evenly for a solid fit between motor and reducer “C” Flange.
Note: A bushing may be supplied for use between the motor shaft and the reducer input shaft . Apply anti-seize compound to inside and outside of
bushing .
Do not operate the reducer without making sure it contains the correct amount of lubricant. Confirm that mounting position on nameplate
matches application requirement. Do not overfill or underfill with oil, or injury to personnel, reducer or other equipment may result.
A unit cannot be used as an integral part of a machine superstructure which would impose additional loads on the unit other than those
imposed by the torque being transmitted either through a shaft-mounted arrangement, and any shaft mounted power transmitting device .
(e .g . sprockets, pulleys, couplings)
For safe operation and to maintain the unit warranty, when changing a factory installed fastener for any reason it becomes the responsibility
of the person making the change to properly account for fastener grade, thread engagement, load, tightening torque and the means of torque
retention .

Lubrication
Carefully follow lubrication instructions and installation manual furnished with the gear reducer . All standard Bravo ® reducers are properly filled at
Factory with sufficient lubricant quantity for nearly any mounting position .
Change oil only when performing maintenance that requires gearbox disassembly or if the reducer is operated in a severe environment . If oil must
be replaced use only Mobil Glygoyle 460 (H1 Food Grade Lube).
Lubricant should be changed more often if gear reducer is used in a severe environment . (ie: humid, wet, caustic, etc)
Do not mix different lubricants in the reducer.
SPECIAL LUBRICATION REQUIREMENTS – Sizes 518-534
• Reducer is mounted with input worm shaft vertical
• Input speed is sustained less than 900 RPM
NOTE: The reducer may require modifications to assure proper
lubrication in these applications . Contact Factory for more details .
