Sharpe Principles of mixing - Tri-Canada

Motors- Primary purpose: Transmit power and torque to the mixers.Mounting Description Motor/Gearbox/CouplingC-Face MotorsStandard on most mixers. Mounts directly on gearbox C-Face input. Registered fit. Easy to install. Available off theshelf for most motor enclosures. Can be mounted verticalor horizontal. Connects to the gearbox via motor coupling.Foot Mounted MotorsMounts to gearbox with a motor scoop. Used for highhorsepower (20 hp and above) or when a C-Face motor isnot available. Connect to gearbox with flexible motorcoupling. (Standard on V-Belt drives).TEFC Mill & Chem.

Gearbox (Speed Reducer) Primary purpose: Reduce or Increase output shaft speed.Output Shaft OptionsHollow BoreHollow bore gearboxes are themost common and costeffectiveway to install a mixershaft onto a gearbox. Theshaft slides up in the drivewithout the need for shaftcoupling. Preferred when usingany type of tank seal.Solid ShaftSolid output shaftsallow the maximumgearbox shaft size.Requires a flanged orsplit style coupling tomount mixer shaft.Gearbox Type Description OptionsE-SeriesRight Angle Worm DrivesThe Sharpe Mixers’ compact E-Seriesworm gear drive is a very versatilehollow bore unit that is typically used in1/3 to 5 hp range with output speeds of5 to 350 rpm. The low profile rightangle design can be tailored to meetmost top entry and side entry mixingapplications up to 10,000 gallons. Ringbase, plate or flange mounted For openor closed tank applications. Available instandard corrosion resistant epoxycoated unit, white washdown unit or allstainless steel construction.(Reasonably priced).N-SeriesR-SeriesDouble Helical Parallel ShaftThe Sharpe Mixers N-Series is an in-linehelical drive with a wide range ofoptions. The units are available inhollow or solid output shafts, up to 50different ratios per case size andtypically used in 1-to-150 hp range.Built with heavy duty tapered rollerbearings and Quadrilip Seals on theoutput shaft. Designed for use in topentry, side entry open and closed tanks.Available with optional leak safe“Effective Drywell” (shown right)designed to prevent the gearboxlubricant from contaminating the mixingmedium. Vertical motor assembly. Highquality for reasonable prices.Heavy Duty RAM drivesSharpe Mixers R-Series is a right anglehelical-Spiral-bevel drive designed tohandle the most demandingrequirements of mixing applications. 5-300 Horse Power. Typically used in hightorque, large tank applications. Unitincludes drywell and oversized drivecomponents. Heavy Duty-ExpensiveOil Safe Design
