Ever-power Model B coupling for light to medium-duty applications
Model B couplings aren’t interchangeable with standard Ever-power couplings.
Sizes 1 1/2 through 3 1/2 with integral end band.
CENTER FLANGE BOLTING
All couplings feature precision-drilled flange bolt holes, and tight tolerance. Grade 5 flange bolts to assure a long-lasting flange to flange and fastener match. Exposed bolt flanges are regular.
Shrouded bolt flanges could be supplied through size 5. Size #5 1/2 and larger couplings are only available with exposed bolt flanges.
MISALIGNMENT CAPABILITIES
Ever-power couplings are made for ± 1/2° static misalignment per fifty percent coupling. Minimizing operating misalignment will maximize the life of the coupling. Refer to the Set up and Alignment Guidelines for alignment recommendations.
Ever-power COUPLING Features & Benefits
IMPROVED SOFT SEAL gives superior sealing under misaligned conditions.
UNIQUE TOOTH FORM using a 40° pressure angle, distributes the load over a larger area than couplings designed to use a 20° pressure position.
FULL TOOTH ENGAGEMENT reduces uneven put on on tooth that results in much longer life plus improved performance.
QUALITY EXPOSED FASTENERS consists of SAE Grade 5 bolts with hex nuts and lock washers. Installation is easy, without special tools. Shrouded bolts optional.
CLEAR Corrosion INHIBITIVE AND CORROSION RESISTANT Surface finish protects coupling in normal industrial environments.
AVAILABLE OFF-THE-SHELF in reborables with large bore features or stock finish bored.
OPTIONAL PILOT RINGS provides positive register between identical halves. Eliminates selective assembly needed in male, female sleeves.
INTERCHANGEABLE by half coupling with competitive coupling designs.
HIGHER MISALIGNMENT CAPABILITY sizes 1-7 compensate for ±1 1/2° static angular misalignment per equipment mesh.
Series H Gear Couplings
Series H couplings of Size 8 to 30 are created for ±1/2° misalignment per flex fifty percent coupling, to pay for misalignment between the shafts in a full-flex coupling. Series H couplings could be supplied in full-flex, flex-rigid, floating shaft and spacer plans as well as custom designs. Only exposed bolt flanges are available in sizes 8 to 30.
The straight-faced, involute stub tooth form is used in the Series H coupling, sizes 8 to 30. This tooth type distributes contact pressures across the full length of the hub tooth, to greatest develop the needed lubricating film, reducing tooth use and extending coupling assistance life for a long time of operation. The End Rings are removable for simple assembly and to enable inspection of the apparatus sets.
Ever-power Gear Couplings
The Ever-power design, with its life time all-metal end ring, provides up to 300% greater lubricant capacity. This implies that longer periods between relubrication could be scheduled.
The all-steel end ring, used exclusively in Ever-power couplings, eliminates the need for any kind of perishable lube seal (o-rings, lip seals, cork gaskets, etc.). The end ring not only provides the dam over which lubricant must circulation to escape, but it additionally pilots the sleeve with respect to the hub during start-up and shut-down operations. It further eliminates partial tooth disengagement with resulting tooth overloads by giving sleeve teeth which are flush against the within wall of the end ring.
It’s the only coupling designed to use oil lubrication.
To make sure that your couplings provide Maximum Life, usually specify Ever-power couplings, with the all-metal end band.
The Straight-Faced involute hub tooth form featured in the Ever-power coupling is virtually unique in the market today. It really is this tooth form that distributes tooth contact pressures over the full length of the hub tooth, best developing the required hydrodynamic lube film, reducing tooth put on and extending coupling existence. It is the only hub tooth form obtainable in the standard Ever-power coupling line.
Ever-power Gear Couplings
FULL ENGAGEMENT TEETH
The Ever-power equipment coupling has been designed with full size tooth engagement with the inherent result of longer existence and improved performance.
OPTIONAL PILOT RINGS
The standard Ever-powercoupling consists of two identical half couplings. Optional precision steel pilot rings can be found when more accurate centering of the two sleeves is required.
HIGH MISALIGNMENT SEAL
Competitive gear couplings incorporate an O-ring seal. To be able to conform with today’s high misalignment capacities, this O-ring must match a groove that’s larger than the ring.Ever-power couplings make use of a truly great misalignment seal that seals remarkably under misaligned circumstances.
Ever-power POWERLIGN
This flangeless design transmits identical torques as the standard Ever-power Coupling. Having a smaller outside diameter, however, it is more small, lighter, and will run at greater speeds. This alternative may be selected for applications where space is bound.
SERIES H Features & Benefits
Higher Misalignment Capability
Sizes 1-7 compensate for ±1 1/2° static angular misalignment per gear mesh.
Minimizing operating misalignment will maximize the life of the coupling. Refer to the Set up and Alignment Instructions for alignment recommendations.
Larger Bore Capabilities permit the most economical size selection for shafts up to 10 5/8″.
Higher Torque Ratings due to bigger tooth pitch diameters than other couplings.
Versatility for the reason that Series H’s are interchangeable by half coupling with competitive coupling styles.
1 1/2° Curved-Face Teeth are a prime feature of the Series H coupling, sizes 1-7. The crowned hub teeth are a 20° full-depth involute tooth form with flank, tip, and root curvature. When
used in combination with the straight confronted sleeve teeth, these 1 1/2° curved face hubs offer increased shaft misalignment capability
CENTER FLANGE BOLTING
All couplings feature precision-drilled 
flange bolt holes, and tight tolerance Grade 5 flange bolts to assure a long-long lasting flange to flange and fastener fit. Exposed bolt flanges are
regular. Shrouded bolt flanges can be supplied through size 5. Size #5 1/2 and larger couplings are only available with uncovered bolt flanges.
LUBRICATION
Each sleeve flange comes with two pipe plugs 180° aside. This permits assembly of a full flex coupling with four lube plugs positioned every 90°, facilitating lubrication. The lube seal is a Buna-N O-ring to help retain grease and exclude contaminants. KHP or KSG coupling greases are recommended in order to obtain maximum working life.
Ever-power COUPLING Features & Benefits
The Ever-power equipment coupling is available in two basic product lines:
Ever-powercoupling for moderate to heavy-duty applications
Sizes 1 1/2 through 7 with essential end ring.
Sizes 8 through 30 with bolt-on end ring.
