Beam Couplings
Ever-power produced beam couplings have substantial angular misalignment capacities, are zero-backlash and also have a balanced design for reduced vibration for speeds up to 6,000 RPM. They are manufactured from a single little bit of aluminum or stainless with multiple sets of spiral cuts to supply bigger stiffness and better all-around misalignment functions than traditional single beam couplings. Ever-electric power beam couplings can be purchased in inch, metric, and inch to metric bore sizes ranging from 3/32″ to 3/4″ and 3mm to 20mm. they are generally used in encoder, tachometer, and lumination duty power tranny applications where precise action control is desired.
Bellows Couplings
Ever-power made bellows couplings have huge torque and torsional stiffness capacities, are zero-backlash, possess a balanced design, and can accommodate all types of misalignment. They happen to be made up of two anodized metal hubs and a stainless steel bellows making a light and portable low inertia coupling capable of boosts to 10,000 RPM. The thin wall of the stainless bellows may easily flex while remaining rigid under torsional loads. Ever-electrical power manufactures bellows couplings hubs with or without keyways in clamp or set screw styles with “, metric, and ” to metric bores which range from 1/8″ to at least one 1″ and 3mm to 25mm. They are generally used in high performance stepper servo devices where precise action control is required.
Controlflex Couplings
Ever-power Controlflex couplings certainly are a three-part assembly with a balanced style made up of two hubs joined to 1 or two middle inserts called frogs. This style creates a compact low inertia versatile coupling capable of speeds up to 25,000 RPM. Clamp style hubs are made with “, metric, keyed, and keyless bores which range from 1/8” to 1-1/2” and 3mm to 40mm for great customizability. The unique style of the frog concentrates forces onto its adaptable limbs allowing for low bearing loads guarding sensitive tiny bearings in applications such as encoders or tachometers. Controlflex couplings will be also electrically isolating because the hubs do not touch and frogs are manufactured from acetal. They happen to be produced by Schmidt-Kupplung in Germany and so are RoHS3 compliant.
Disc Couplings
Ever-power produced disc couplings have great torque and torsional stiffness capacities, are zero-backlash, possess a balanced design, and may accommodate all kinds of misalignment. They happen to be created in single disc designs for small installations and double disc styles for higher misalignment capabilities. Ever-electrical power disc couplings are comprised of two anodized lightweight aluminum hubs, stainless disc springs, and a center spacer (double disc only) creating a light low inertia coupling with the capacity of speeds up to 10,000 RPM. Hubs are manufactured with or without keyways in clamp and established screw types with bore sizes ranging from 1/8″ to 1-1/4″ and 3mm to 32mm. They are commonly used in powerful stepper servo systems where precise motion control is required.
Jaw Couplings
Ever-power created zero-backlash jaw couplings possess an extremely customizable three-piece design, have high dampening functions, and may accommodate all kinds of misalignment. The two aluminium hubs press in shape onto an elastomeric middle spacer named “the spider” enabling regular zero-backlash operation. Ever-ability zero-backlash jaw couplings have a balanced design and style for decreased vibration at speeds up to 8,000 RPM. Hubs are manufactured with or without keyways in clamp or placed screw types with bore sizes ranging from 1/8″ to 1-1/4″ and 3mm to 32mm. Spiders are available in three durometers enabling the user to match coupling performance with system requirements. Zero-backlash jaw couplings are generally found in applications with great acceleration/deceleration curves where dampening and exact motion control are required.
Oldham Couplings
Ever-power produced oldham couplings have an extremely customizable three-piece style, are zero-backlash, and also have huge parallel misalignment functions. Two anodized lightweight aluminum hubs press fit into the mating slots of the guts disk enabling zero-backlash operation and low bearing loads. Ever-power oldham couplings possess a balanced design and style for decreased vibration at boosts to 4,500 RPM. Hubs are made with or without keyways in clamp or placed screw types with bore sizes which range from 1/8″ to 1-1/4″ and 3mm to 30mm. Disks are available in three supplies allowing the user to complement coupling performance with program requirements. They are generally found in stepper servo systems that require a higher parallel misalignment coupling.
Slit Couplings
Ever-power slit couplings will be an alloy, one part configuration made to provide smooth tranny of motion, high torsional stiffness, low bearing loads, and long life. The slot design provides the best balance between zero backlash, torsional stiffness and low bearing load. With two units of identical slots, the mini slit coupling is normally constant velocity by design and handles angular, parallel and axial offset. Obtainable in 6 and 8 mm diameters and allowable boosts to 70,000 rpm, slit couplings certainly are a reliable one piece coupling design that approaches the overall performance of a bellows coupling.
Rotating shaft-driven mechanical components are commonly found in all varieties of machinery that accomplish the various processes and functions of modern industry.
o Shaft misalignment will place stresses on shafts and related parts of the assembly such as for example bearings, which can result in early failure of both.
o Shaft ends can be misaligned radially or perhaps angularly, exhibit axial displacement, or experience a combination of all three.
o Drive couplings can be used to pay for shaft misalignment, whether the misalignment can be an intentional or perhaps an unintentional section of the design.

Ever-powerdrive couplings happen to be power transmission elements used to couple the shafts of varied mechanical devices, and to compensate for shaft misalignment, reducing stress on shafts and bearings. Beam-style couplings are made for servo applications, supplying the flexibility of bellows couplings plus torsional stiffness and power of disc couplings.

SERVO COUPLINGS
Servo couplings from Ever-power can be purchased in a wide variety of styles, sizes, and resources to match differing app requirements. Choosing the correct servo coupling could be a difficult method which involves many performance elements which includes: shaft misalignment, RPM, space requirements, torque, and others. Matching a shaft coupling with these elements is crucial to system efficiency. Ever-power gives servo couplings in rigid, beam, bellows, curved jaw, disc, and oldham types allowing the user to select the coupling that greatest fits their request. All Ever-electrical power couplings are zero-backlash and manufactured in our Marlborough, MA factory.
Servo couplings can be found in lots of different attachment styles as well as a vast selection of sizes and components to suite your specific application and/or customized requirements. Maintaining optimum system performance relies on correctly complementing a shaft coupling based on your specific performance and app requirements and expectations. At Helical, we have used the guesswork out of selecting the precise servo coupling for the application by factoring in vital component dynamics such as for example shaft misalignment, space requirements, torque, and RPM.
