1 0 rigid or flexible coupling l.jpg

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


1 0 1 types of flexible couplings l.jpg

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


1 0 2 flexible coupling elastomeric types l.jpg

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


1 1 jaw coupling compression type l.jpg

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


1 1 1 features of maska starflex coupling l.jpg

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

1 1 3 element material l.jpg

1.1.3 Element material

A. NBR – Buna-N

B. Urethane

C. Hytrel

D. Bronze

MASKA 2009-M2


1 1 4 element material nbr l.jpg

1.1.4 Element material - NBR

Most commonly used element material for all general applications - Pumps, gear box, etc.

MASKA 2009-M2


1 1 5 element material urethane l.jpg

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


1 1 6 element material hytrel l.jpg

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


1 1 7 element material bronze l.jpg

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

1 3 features of maskaflex coupling l.jpg

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.

**All size available excepted “S” **

MASKA 2009-M2


2 1 weld on hub qd25 l.jpg

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

2 4 xt hubs bushings l.jpg

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


2 4 xt hubs bushings29 l.jpg

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


2 5 xt hub bushing designation l.jpg

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

3.0 Short QD bushings

short QD “J”

Standard QD “J”

MASKA 2009-M2


Slide32 l.jpg

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.
