Fastener Tightening Torques
Use the tightening torque values specified in Table 1 for fastening
gear drives, motors and accessories to their mounting surfaces
with un-lubricated fasteners. DO NOT use these values for
“torque locking” fasteners or for fastening components with
aluminum feet or soft gaskets or vibration dampeners on the
mounting surface. If the tightening torque exceeds the capacity of
the torque wrench, use a torque multiplier. Use ISO property
class 8.8 for metric fasteners. See Table 7, Page 6 for fastener
and wrench size.
Water Cooling
WATER COOLED HEAT EXCHANGERS — Install a shut-off or
control valve in the water line to the heat exchanger to regulate
the water flow through the exchanger. Also install a water flow
gauge between the control valve and the exchanger to
determine actual flow rate. Discharge water to an OPEN
DRAIN to prevent back pressure.
INTERNAL COOLING TUBES — Refer to Factory.
Lubrication Systems
SPLASH LUBRICATED DRIVES — Standard horizontal shaft
type DH & DB drives are splash lubricated. The lubricant is
picked up by the revolving elements and distributed to the
bearings and gear meshes.
OIL PUMP LUBRICATED DRIVES (OPTIONAL) — Standard
horizontal shaft type DH & DB drives can be equipped with an
internal gear driven oil pump. The system consists of an
automatic reversing pump, driving gears and internal
distribution. The system can be used for improved thermal
capacity and lubrications accessories, i.e. filters. The pump
system is rotation independent.
Lubrication Requirements
Carefully follow lubrication instructions on the gear drive
nameplate, warning tags, and installation manuals furnished
with gear drive. Failure to follow instructions voids warranty.
Petroleum Based Lubricants
Industrial type (not automotive) petroleum based
sulfur-phosphorous extreme pressure (EP) gear lubricants
meeting specific requirements are required for ambient air
temperatures of -9°C to +52°C (15°F to 125°F). An approved
lubricant MUST be used. Approved lubricants meeting the
specific requirements are listed in Table 4. Lubricants not listed
may be used only after approval from Factory. Failure to use an
approved lubricant voids warranty.
For drives operating outside the above temperature range refer
to the “Synthetic EP Lubricants” section. Synthetic lubricants can
also be used in normal climates.
WARNING: EP LUBRICANTS IN FOOD PROCESSING
INDUSTRY —
EP lubricants may contain toxic substances and
should not be used in the food processing industry without the
lubricant manufacturer’s approval. Lubricants which meet
USDA or NSF “H-1” classification are suitable for food
processing applications. Consult Factory.
Viscosity
The proper grade for EP lubricants is found in Table 2. For cold
and normal climate conditions refer to Table 3, and the
“Synthetic EP Lubricant” section.
OIL PUMPS — When selecting a lubricant for a gear drive
equipped with an oil pump, cold temperature oil viscosity is
very important. Lubricant viscosity at start-up generally should
not exceed 2160 cSt (10,000 SSU). When exceeding this
viscosity, pump cavitation is possible, reducing oil circulation to
gear drive and possibly damaging the pump. A sump heater
may be required or it may be possible to use a lower viscosity
oil to minimize pump cavitation, refer to Factory.
