Falk™ RAM® Mixer Gear Drives Gear Drives - BSI Mechanical

FALK RAM ® MIXER DRIVESMixer Drives Designed to Drive MixersRAM Mixer Drives are engineered and built specificallyto handle the unique and demanding requirements ofmixing applications.RAM Mixer Drives can handle the rough mixingrequirements in industries like food processing, wasteand water treatment, chemical processing, pulp andpaper, pharmaceutical, power generation, and mining.With a wide range of sizes available, there’s a RAM MixerDrive for virtually any mixing application. Best of all,every RAM is fully backed by Rexnord’s Falk GearGroup—one of the most trusted names in industry forover 100 years.What sets RAM apart is its unique designOrdinary commercial gear drives can’t stand up to typicalmixing requirements—high bending and thrust loads onthe output shaft, reliable round-the-clock operation, andabsolutely no leakage of gear lubricant into the productbeing mixed.RAM is no ordinary gear drive. It’s designed specificallyfor the rigorous requirements of mixing service. Falkmixer drives have been around for 50 years.Unique RAM Features: Large-diameter, high-capacity output shafts toaccommodate the high-bending moment loadscommon in mixing applications. Extended bearing life–minimum 30,000 hoursL-10 at 1.25 service factor even at high thrust andmoment loads. No-leak drywell design physically separates the oilsump from the output shaft to eliminate gear oilcontaminations of your product. Rugged cast or fabricated housings designed towithstand the stresses of mixing while maintainingaccurate gear alignment. Helical and spiral-bevel gearing for quiet operationsand high drive efficiency. Product flexibility for handling almost any type ofinstallation. RAM mixer drives are available withsolid or hollow output shafts, and can be adaptedto top, bottom or side entry mixing.RAM HMX Mixer DrivesFor small-capacity mixing Hollow output shaft Top or side entry Up to 22,000 lb-in output torque 5.06:1 to 31.30:1 ratiosDesigned for small-capacity, tough-duty mixingapplications, the RAM HMX is a hollow shaft drive for topor side entry applications. It incorporates many of the sameconstruction and performance features found on ourmedium- and large-capacity mixer drives.Rugged Cast-Iron Housing – Accepts mixing stresses whilemaintaining accurate gear alignment and resisting corrosion.Convenient C-Face Motor Adapter – This fully registeredadapter ensures fast, positive motor alignment, eliminates hassleswith V-belts, sheaves and guards, and simplifies installation with aflexible coupling.Mounting Flexibility – Various mounting configurations,including vertical and horizontal shaft with ASA flange and soliddrive shaft options, accommodate a wide range of applications. Allconfigurations feature a male register for accurate alignment.High-Strength HelicalGearing – All-helical gearing Type HMXis designed for high efficiencyand maximum load carryingcapacity with reserve strengthrating.No-Leak DrywellConstruction – Oil sump isisolated from output shaft toprevent gear lubricants fromleaking and contaminating theproduct being mixed.Optional Stub Shaft – Available with high-strength, alloy-steelstub shaft and coupling hub to easy connect/disconnect to mixershaft.Severe-Duty Seals – Shielded, grease-purgeable upper sealsprovide a grease barrier that traps water, dirt and abrasivecontaminants before they can enter the drive and cause damage.Low-Speed Tapered Bushing/Adapter – Ensures a solidconnection with the mixer shaft and allows for easy installationand positive removal of shafts for various diameters.Unique Low Speed Bearing Arrangement – High capacity,spherical-roller, mixer shaft bearing isolates impeller loads fromgearing and provides a high moment capacity. Tapered rollerbearings accept high thrust loads in either direction.Re-greasable Low Speed Bearings – Low speed bearings aregrease lubricated, and are field re-greasable for easy maintenanceand longer life.2

Rugged Steel Housing – Fabricated steel housingeffectively resist shock loads and stresses associated with mixingapplications and maintains accurate gear alignment.Large Oil Capacity – Lowers operating temperatures to help oilretain higher viscosity, extending gear, bearing and seal life.Auxiliary cooling systems are also available.Proven High-Hardness Helical Gearing – Engineered toexceed AGMA standards with a reserve strength rating, thesurface-hardened, precision-ground, long-life helical gears delivera smooth, strong, efficient power flow. Large tooth profileprovides extra strength to handle high-shock loads.Precision Spiral Bevel Gearing – Surface hardening andfinish lapping ensure smooth, quiet operation and greater gearefficiency.Oversized Alloy Steel Shaft – Considerably larger in diameterFALK RAM ® MIXER DRIVESSeries LBX, LHX, & MDXShared Featuresthan standard gear drive output shafts, the solid alloy steel shafthas adequate stiffness to withstand high mixer propeller loads.No-Leak Drywell Low-Speed Construction – Adrywell isolates the low-speed output shaft from the oil sump toprevent oil sump lubricants from leaking and contamination.Comprehensive Leak Protection – Covers, shims,gaskets and blind-tapped end cover holes help retain lubricant,eliminate oil leakage and keep contaminants out to reducemaintenance and downtime.Optional Hollow Output Shaft – Available with a hollow shaftoutput connection for mixer shaft insertion.Comprehensive Leak Protection – Covers, shims,gaskets and blind-tapped end cover holes help retain lubricant,eliminate oil leakage and keep contaminants out to reducemaintenance and downtime. A standard magnetic oil drain plugis standard.RAM MDX Mixer DrivesFor medium-capacity mixing Solid or hollow output shaft Top, bottom or side entry Up to 166,000 lb-in output torque 5.06:1 to 1207:1 ratiosIdeal for medium-capacity mixing needs, the rugged RAMMDX has beenperformance-proventhrough years ofoperations in adiverse range ofdemandinginstallations.As replacementdrives RAM MDXhas equal or higherType MDXratings than Mixco“Lightnin” 70, 80,TE, and RE Series, and Chemineer HT series.Larger, Long-Life, Grease-Lubricated Bearings – With aminimum L-10 life at least three times that of standardcommercial drives - and in excess of industry standards formost applications - the upper and lower output shaft taperedroller bearings withstand high impeller loads and insuremaximum life. A grease baffle on the upper bearing retainsgrease and prevents it from entering the drive.Fast, Easy Ratio Changes – With helical gearing containedin the high-speed head, the RAM MDX gives youmaximum ratio flexibility. To change ratios, simply replace thepinion and gear. For a reduction change, just replace thehigh-speed head with optional helical gears readily availablefrom stock.RAM LHX & LBX Mixer DrivesFot large-capacity mixing Solid or hollow output shaft Top, bottom or side entry Up to 4,000,000 lb-in torque LHX Ratios: 5.60:1 to 437.9:1 LBX Ratios: 13.95:1 to 357.5:1Available in both right angle and parallel gear drive configurations,the RAM LHX and LBX Series Mixer Drives are heavy-duty mixerdrives designed for the largest-capacity mixing applications.External Forced-Lubrication System – An externally-mounted,electric-motor-driven oil pump with a filter deliversgenerous, positive lubrication to all gearing and bearing elementsto help extend drive life.Larger, Long-Life Bearings – With a minimum L-10 life threetimes that ofcommercial drives -and in excess ofindustry standards formost applications - theoutput shaft bearingswithstand high mixerpropeller loads andinsure maximum life incontinuous mixingapplications.Type LBXQuick Oil Checks –Standard, automotive-type dipstick allows fast, easy checks of oillevel.3
