Gear Coupling

Ever-power Model B coupling for light to medium-duty applications
Model B couplings are not interchangeable with regular Ever-power couplings.
Sizes 1 1/2 through 3 1/2 with integral end band.
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. Uncovered bolt flanges are standard.
Shrouded bolt flanges could be supplied through size 5. Size #5 1/2 and larger couplings are only available with exposed bolt flanges.

Ever-power couplings are made for ± 1/2° static misalignment per half coupling. Minimizing working misalignment will maximize the life of the coupling. Make reference to the Set up and Alignment Instructions for alignment recommendations.

Ever-power COUPLING Features & Benefits

IMPROVED SOFT SEAL gives superior sealing less than misaligned conditions.
UNIQUE TOOTH FORM utilizing a 40° pressure angle, distributes the strain over a more substantial area than couplings designed to use a 20° pressure angle.
Total TOOTH ENGAGEMENT reduces uneven use on tooth that results in much longer life 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 FINISH protects coupling in normal industrial environments.
AVAILABLE OFF-THE-SHELF in reborables with huge bore capabilities or stock finish bored.
OPTIONAL PILOT RINGS provides positive register between identical halves. Eliminates selective assembly required in male, female sleeves.
INTERCHANGEABLE by half coupling with competitive coupling styles.
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 designed for ±1/2° misalignment per flex half coupling, to pay for misalignment between the shafts in a full-flex coupling. Series H couplings can be provided in full-flex, flex-rigid, floating shaft and spacer plans as well as custom designs. Only exposed bolt flanges can be found in sizes 8 to 30.

The straight-faced, involute stub tooth form can be used in the Series H coupling, sizes 8 to 30. This tooth form distributes contact pressures over the full amount of the hub tooth, to best develop the required lubricating film, minimizing tooth use and extending coupling support life for a long time of operation. The End Rings are removable for ease of assembly and to enable inspection of the gear sets.
Ever-power Gear Couplings

The Ever-power design, using its lifetime all-metal end band, provides up to 300% greater lubricant capacity. This implies that longer intervals between relubrication could be scheduled.

The all-metal end ring, used exclusively in Ever-power couplings, eliminates the necessity for any kind of perishable lube seal (o-rings, lip seals, cork gaskets, etc.). The finish ring not only supplies the dam over which lubricant must circulation to escape, but 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 giving sleeve tooth which are flush against the inside wall of the end ring.

It’s the only coupling made to use oil lubrication.

To make sure that your couplings provide Maximum 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 virtually unique in the industry today. It really is this tooth type that distributes tooth contact pressures across the full amount of the hub tooth, best developing the required hydrodynamic lube film, minimizing tooth use and extending coupling existence. It is the just hub tooth form obtainable in the typical Ever-power coupling line.

Ever-power Gear Couplings

The Ever-power gear coupling has been made with full size tooth engagement with the inherent result of longer lifestyle and improved performance.

The standard Ever-powercoupling contains two identical half couplings. Optional precision metal pilot rings can be found when more accurate centering of the two sleeves is required.

Competitive gear couplings integrate an O-ring seal. To be able to conform with today’s high misalignment capacities, this O-ring must fit into a groove that’s larger than the ring.Ever-power couplings make use of a truly high 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 sized outside diameter, nevertheless, it is more compact, lighter, and will run at better speeds. This alternative may be chosen for applications where space is limited.

SERIES H Features & Benefits

Higher Misalignment Capability
Sizes 1-7 compensate for up to ±1 1/2° static angular misalignment per equipment mesh.
Minimizing operating misalignment will maximize the life span 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 bigger tooth pitch diameters than additional couplings.
Versatility in that Series H’s are interchangeable by fifty percent coupling with competitive coupling styles.
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, suggestion, and root curvature. When
used with the straight confronted sleeve teeth, these 1 1/2° curved face hubs offer increased shaft misalignment capability
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 supplied through size 5. Size #5 1/2 and larger couplings are only obtainable with uncovered bolt flanges.

Each sleeve flange is supplied 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 can be a Buna-N O-ring to help retain grease and exclude contaminants. KHP or KSG coupling greases are suggested to be able to obtain maximum working life.

Ever-power COUPLING Features & Benefits

The Ever-power gear coupling comes in two basic products:

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.
