  1. Baldor’s Mission Statement is to be the best (as determined by our customers) marketers, designers and manufacturers of industrial electric motors, mechanical power transmission products, drives, and generators. MASKA 2009-M2

  2. COMPLEMENTARY MASKA PRODUCTS 1. Couplings 2. Weld-on hub (XT & QD) 3. QD Short Bushing 4. 1VP& 2VP PULLEYS MASKA 2009-M2

  3. Rigid coupling Flexible coupling 1.0 RIGID OR FLEXIBLE COUPLING? • Used to connect shafts that are precisely aligned • Accommodates misalignment • Dampen vibrations or shock load • Used for most industrial applications, rather than rigid coupling, because of these multiple functions MASKA 2009-M2

  4. 1.0.1 TYPES OF FLEXIBLE COUPLINGS A. Metallic types • Torsional stiffness • Operates in relatively high ambient temperature and/or in presence of certain oils or chemicals • Electric motor drive only - not recommended for combustion engine • Applications with relatively constant loads B. Elastomeric types • Torsional softness (absorbs shock and vibration) • Allows more angular misalignment between shafts • Lower cost and lighter weight • Smoother and quieter operations MASKA 2009-M2

  5. 1.0.2 Flexible coupling - Elastomeric types Maska Starflex: • compression type can transmit more torque in less space and easy to install 4-FLEX: • shear type allows torsional wind-up and transmits higher torque Maskaflex: • shear type coupling generally produces lower shaft loads when submitted to parallel offset misalignment MASKA 2009-M2

  6. 1.1 Jaw Coupling - compression type • First patented in 1927 • Simple design - three components: two hubs and one elastomeric element • It is called a compression type coupling, because torque is transmitted by conversion between the driver hub and the driven hub MASKA 2009-M2

  7. 1.1.1 Features of MaskaStarflexcoupling • Fail-safe when equipment cannot be allowed to stop. If the elastomeric element should fail, the coupling will still transmit the torque due to the metal-to-metal contact. • Great capability to handle torque over loads or spike • Simple to install, compact and low cost • Angular misalignment is more limited than in shear-design MASKA 2009-M2

  8. 1.1.2 MaskaStarflexcoupling MASKA 2009-M2

  9. 1.1.3 Element material A. NBR – Buna-N B. Urethane C. Hytrel D. Bronze MASKA 2009-M2

  10. 1.1.4 Element material - NBR Most commonly used element material for all general applications - Pumps, gear box, etc. MASKA 2009-M2

  11. 1.1.5 Element material - Urethane • Greater torque capacity than rubber • Good abrasion / wear resistance • Better resistance to environmental conditions such as ozone, ultraviolet and some oils or chemicals agents. • Should not be used in cyclic or start/stop applications • Limited to 160°F MASKA 2009-M2

  12. 1.1.6 Element material - Hytrel • Higher torque capacity than rubber and urethane • Best chemical resistance, compared to urethane and maximum temperature of 250°F • Angular misalignment less than urethane and rubber. 1/2 ° compare to 1 ° • As urethane, should not be use in frequent start/stop applications or regular shocks and vibrations MASKA 2009-M2

  13. 1.1.7 Element material - Bronze • Not elastomeric, but an option for high temperatures, such as 450 °F • Could be used in salt/marine applications • Only used in slow speeds, generally below 250 rpm, since it’s a metal-to-metal contact which increases wear MASKA 2009-M2

  14. 1.1.8 Element material Technical Chart – Maska Starflexelement MASKA 2009-M2

  15. 1.1.9 MaskaStarflexcoupling selection • Coupling selection • Rated Torque chart MASKA 2009-M2

  16. 1.2 4-FLEX - Shear type MASKA 2009-M2

  17. 1.2.1 4-FLEX Product description • 4-way flexing action • All types & sizes in cast iron • No lubrication; smooth, quiet power transmission • Fast & easy installation; no special tools or accessories required • Precise concentrical product to avoid run-out and unbalance • Flanges and sleeves manufactured in Canada MASKA 2009-M2

  18. 1.2.2 4-FLEX Technical Features • Tight bore tolerance (+.0005 / +.0015) • Over 1000 HP @ 1750 rpm • J & S flanges are bored to size • B flanges are mounted with a QD bushing MASKA 2009-M2

  19. 1.2.3 4-FLEX General Characteristics MASKA 2009-M2

  20. 1.3 Features ofMaskaflexcoupling • Compared to other couplings in the industry, the tire coupling is the most suitable for applications with shock loads, angular misalignment up to 4 degrees or end float up to ¼ inches. • It is made of natural rubber and reinforced tension member bonded together. The element has a special series of cables near the flange attachment that offers longer life expectancy and prevents premature shear failure. MASKA 2009-M2

  21. 1.3.1 Features ofMaskaflexcoupling ANGULAR MISALIGNEMENT Up to 4 deg. AXIAL OFFSET Up to 0.25" PARALLEL MISALIGNEMENT Up to 0.125" MASKA 2009-M2

  22. 2.0 WELD-ON HUBS FAMILY 1) QD SERIES - GENERAL APPLICATIONS 2) XT SERIES - CONVEYOR PULLEY ************************************************************ WELD-ON HUBS ARE MADE OF STEEL TO FACILITATE WELDING ************************************************************ MASKA 2009-M2

  23. 2.1 Weld-On Hub QD H – QD PART# **All size available excepted “S” ** MASKA 2009-M2

  24. 2.1 Weld-On Hub QD Product Features & applications • The QD weld-on hub are used in a wide range of applications such as plate steel sprocket, conveyor and fan blades. • All Maska Weld-on hub are made of steel since cast iron is difficult to weld. Once a material contains a high level of carbon, this will reduce welding capabilities. • Maska QD bushings have a synchronized keyway with bolt holes so they can be easily used once two of these need to be installed face to face on the same keyed shaft MASKA 2009-M2

  25. 2.2 XT HUBS & BUSHINGS MASKA 2009-M2

  26. 2.3 XT Conveyor pulley MASKA 2009-M2

  27. 2.4 XT Hubs & Bushings Product features • Not interchangeable with QD or any other bushing even if it has a similar design. • Supply with hexagonal head cap screws and spring lock washers like QD bushings for installation. • Van Gorp / Browning is the original manufacturer of these kind of weld-on hubs MASKA 2009-M2

  28. 2.4 XT Hubs & Bushings • Taper is 2" per foot compared to QD which has ¾ per foot. • XT bushings are shorter compared to QD and will only fit in these hubs (XTH). • Only sizes XTB100 & XTB120 are made of gray cast iron. MASKA 2009-M2

  29. 2.5 XT HUB & BUSHING DESIGNATION MASKA OFFERS STANDARD SIZES • Bore sizes in stock match with popular bearing housing sizes to support the shaft-conveyor pulley assembly. • XTB Series number corresponds approximately to the max. bore per model like Taper-Lock bushings nomenclature MASKA 2009-M2

  30. 3.0 Short QD bushings short QD “J” Standard QD “J” MASKA 2009-M2

  31. 3.0 QD BUSHING “SHORT” • Same features than the QD but with a shorter barrel or taper length. 100% interchangeable with competitors. • Short QD bushings are only available from J through S. • Supplied with shorter Hexagonal bolts than QD but still comes with set screw and lock washers • Would not be appropriate on v-belt pulley since stability is required for multiple grooves pulley so they are generally used face to face with conveyor pulley or alone with a steel plate sprocket, blade, impellers that are not too wide. MASKA 2009-M2

  32. 4.0 VP- SERIES DESIGNATION MASKA OFFERS ALL SIZES MASKA 2009-M2

  33. 4.1 Variable pitch sheaves - VP series 1VP & 2VP • The VP series is equivalent to 8000 series. The 8000 series generally offers a wider range of speed. • Designed for A (4L), B (5L) and 5V belts. 3L could also be used • Offers half turn adjustment up to 6 turns. • All made of gray cast iron MASKA 2009-M2

  34. 4.2 VP types TYPE1 - WITHOUT A KEY ONLY SET SCREWS OVER THE HUB TYPE 2- WITH A KEY THROUGH THE HUB ****Only one set screw per flange like Browning**** MASKA 2009-M2
