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 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 exposed bolt flanges.
MISALIGNMENT CAPABILITIES
Ever-power couplings are made for ± 1/2° static misalignment per half coupling. Minimizing working 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 presents superior sealing in misaligned conditions.
UNIQUE TOOTH FORM utilizing a 40° pressure position, distributes the strain over a larger area than couplings designed to use a 20° pressure angle.
FULL TOOTH ENGAGEMENT reduces uneven put on on tooth that results in much longer lifestyle plus improved performance.
QUALITY EXPOSED FASTENERS includes SAE Grade 5 bolts with hex nuts and lock washers. Installation is simple, without special tools. Shrouded bolts optional.
CLEAR Corrosion INHIBITIVE AND CORROSION RESISTANT Surface finish protects coupling in regular industrial environments.
AVAILABLE OFF-THE-SHELF in reborables with large bore features or stock finish bored.
OPTIONAL PILOT Bands provides positive register between similar halves. Eliminates selective assembly required in male, feminine sleeves.
INTERCHANGEABLE by fifty percent coupling with competitive coupling styles.
HIGHER MISALIGNMENT Ability sizes 1-7 compensate for ±1 1/2° static angular misalignment per gear mesh.
Series H Gear Couplings
Series H couplings of Size 8 to 30 are designed for ±1/2° misalignment per flex fifty percent coupling, to compensate for misalignment between your shafts in a full-flex coupling. Series H couplings could be provided in full-flex, flex-rigid, floating shaft and spacer arrangements along with custom designs. Just exposed bolt flanges can be found 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 amount 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 End Rings are removable for ease of assembly and to enable inspection of the apparatus sets.
Ever-power Gear Couplings
The Ever-power design, with its lifetime all-metal end band, provides up to 300% greater lubricant capacity. This means that longer periods between relubrication could be scheduled.
The all-metal end ring, used exclusively in Ever-power couplings, eliminates the necessity for any type of perishable lube seal (o-rings, lip seals, cork gaskets, etc.). The end ring not only provides the dam over which lubricant must flow to escape, nonetheless it additionally pilots the sleeve with regards to the hub during start-up and shut-down functions. It further eliminates partial tooth disengagement with resulting tooth overloads by providing sleeve tooth which are flush against the within wall of the end ring.
It is the only coupling designed to use oil lubrication.
To make certain that your couplings provide Maximum Life, often 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 is this tooth form that distributes tooth get in touch with pressures across the full length of the hub tooth, best developing the required hydrodynamic lube film, minimizing tooth put on and extending coupling existence. It is the only hub tooth form available in the typical 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 consequence of longer lifestyle and improved performance.
OPTIONAL PILOT RINGS
The standard Ever-powercoupling includes two identical half couplings. Optional precision metal pilot rings are available when more accurate centering of the two sleeves is required.
HIGH MISALIGNMENT SEAL
Competitive gear couplings incorporate an O-ring seal. In order to conform with today’s high misalignment capacities, this O-ring must fit into a groove that is larger than the ring.Ever-power couplings use a truly large 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 can run at better speeds. This alternative could be chosen for applications where space is limited.
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 Installation and Alignment Guidelines for alignment recommendations.
Larger Bore Capabilities permit the most economical size selection for shafts up to 10 5/8″.
Higher Torque Ratings due to larger tooth pitch diameters than various 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 faced 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
standard. Shrouded bolt flanges could 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° aside. This permits assembly of a complete flex coupling with four lube plugs positioned every 90°, facilitating lubrication. The lube seal is certainly a Buna-N O-ring to greatly help retain grease and exclude contaminants. KHP or KSG coupling greases are suggested in order to obtain maximum working life.
Ever-power COUPLING Features & Benefits
The Ever-power gear 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 band.
