Ever-power Model B coupling for light to medium-duty applications
Model B couplings are not interchangeable with standard Ever-power couplings.
Sizes 1 1/2 through 3 1/2 with integral end ring.
CENTER FLANGE BOLTING
All couplings feature precision-drilled flange bolt holes, and tight tolerance. Grade 5 flange bolts to make sure a long-lasting flange to flange and fastener suit. Exposed bolt flanges are standard.
Shrouded bolt flanges can be supplied through size 5. Size #5 1/2 and bigger couplings are only available with uncovered bolt flanges.
MISALIGNMENT CAPABILITIES
Ever-power couplings are created for ± 1/2° static misalignment per half coupling. Minimizing operating misalignment will increase 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 less than misaligned conditions.
UNIQUE TOOTH FORM using a 40° pressure position, distributes the load over a more substantial area than couplings which use a 20° pressure angle.
FULL TOOTH ENGAGEMENT reduces uneven put on on teeth that results in longer existence plus improved performance.
QUALITY EXPOSED FASTENERS includes SAE Grade 5 bolts with hex nuts and lock washers. Installation is simple, without special equipment. Shrouded bolts optional.
CLEAR Corrosion INHIBITIVE AND CORROSION RESISTANT FINISH protects coupling in normal industrial environments.
AVAILABLE OFF-THE-SHELF in reborables with huge bore capabilities or stock finish bored.
OPTIONAL PILOT Bands provides positive register between identical halves. Eliminates selective assembly required in male, feminine sleeves.
INTERCHANGEABLE by fifty percent coupling with competitive coupling styles.
HIGHER MISALIGNMENT CAPABILITY sizes 1-7 compensate for up to ±1 1/2° static 
angular misalignment per gear mesh.
Series H Gear Couplings
Series H couplings of Size 8 to 30 are made for ±1/2° misalignment per flex half coupling, to compensate for misalignment between your shafts in a full-flex coupling. Series H couplings can be supplied in full-flex, flex-rigid, floating shaft and spacer plans and also custom designs. Just exposed bolt flanges can be found in sizes 8 to 30.
The straight-faced, involute stub tooth form is utilized in the Series H coupling, sizes 8 to 30. This tooth type distributes contact pressures across the full length of the hub tooth, to best develop the needed lubricating film, minimizing tooth wear and extending coupling assistance life for a long time of operation. THE FINISH Rings are detachable for ease of assembly and to allow inspection of the gear sets.
Ever-power Gear Couplings
The Ever-power design, using its life time all-metal end band, provides up to 300% greater lubricant capacity. This implies that longer intervals between relubrication could be scheduled.
The all-steel end ring, used exclusively in Ever-power couplings, eliminates the need for any type of perishable lube seal (o-rings, lip seals, cork gaskets, etc.). The finish ring not only provides the dam over which lubricant must flow to escape, nonetheless 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 is the only coupling made to use oil lubrication.
To make sure that your couplings provide Optimum Life, constantly specify Ever-power couplings, with the all-metal end band.
The Straight-Faced involute hub tooth form featured in the Ever-power coupling is practically unique in the industry today. It really is this tooth form that distributes tooth contact pressures over the full length of the hub tooth, greatest developing the required hydrodynamic lube film, minimizing tooth use and extending coupling life. It is the just hub tooth form obtainable in the standard Ever-power coupling line.
Ever-power Gear Couplings
FULL ENGAGEMENT TEETH
The Ever-power gear coupling has been made with full length 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 metal pilot rings can be found when even more accurate centering of both 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 large misalignment seal that seals remarkably under misaligned circumstances.
Ever-power POWERLIGN
This flangeless design transmits identical torques as the typical Ever-power Coupling. Having a smaller outside diameter, nevertheless, it is more compact, lighter, and may run at higher speeds. This alternative may be chosen 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 working misalignment will maximize the life span of the coupling. Make reference to the Installation and Alignment Guidelines for alignment recommendations.
Larger Bore Capabilities allow the most economical size selection for shafts up to 10 5/8″.
Higher Torque Ratings due to larger tooth pitch diameters than other couplings.
Versatility in that Series H’s are interchangeable by half coupling with competitive coupling designs.
1 1/2° Curved-Face Teeth are a primary feature of the Series H coupling, sizes 1-7. The crowned hub teeth are a 20° full-depth involute tooth type with flank, tip, and root curvature. When
used with the straight faced sleeve teeth, these 1 1/2° curved face hubs offer elevated shaft misalignment capability
CENTER FLANGE BOLTING
All couplings feature precision-drilled flange bolt holes, and tight tolerance Grade 5 flange bolts to make sure a long-enduring flange to flange and fastener fit. Exposed bolt flanges are
standard. Shrouded bolt flanges can be provided 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° apart. This permits assembly of a full flex coupling with four lube plugs positioned every 90°, facilitating lubrication. The lube seal is usually a Buna-N O-ring to greatly help retain grease and exclude contaminants. KHP or KSG coupling greases are recommended to be able to obtain maximum operating life.
Ever-power COUPLING Features & Benefits
The Ever-power gear coupling is available in two basic product lines:
Ever-powercoupling for medium to heavy-duty applications
Sizes 1 1/2 through 7 with integral end ring.
Sizes 8 through 30 with bolt-on end band.
