Beam Couplings
Ever-power created beam couplings have excessive angular misalignment capabilities, are zero-backlash and also have a balanced design for reduced vibration by boosts to 6,000 RPM. They are made from a single piece of aluminum or stainless with multiple models of spiral cuts to supply higher stiffness and better all-around misalignment capacities than traditional solo beam couplings. Ever-electricity beam couplings are available in inch, metric, and inch to metric bore sizes which range from 3/32″ to 3/4″ and 3mm to 20mm. they are commonly found in encoder, tachometer, and lumination duty power tranny applications where precise action control is desired.
Bellows Couplings
Ever-power produced bellows couplings have excessive torque and torsional stiffness capabilities, are zero-backlash, possess a balanced design, and will accommodate all kinds of misalignment. They are made up of two anodized light weight aluminum hubs and a stainless bellows making a light-weight low inertia coupling capable of speeds up to 10,000 RPM. The thin wall structure of the stainless bellows may easily flex while remaining rigid under torsional loads. Ever-electric power manufactures bellows couplings hubs with or without keyways in clamp or collection screw styles with “, metric, and ” to metric bores ranging from 1/8″ to 1 1″ and 3mm to 25mm. They are generally used in high performance stepper servo devices where precise movement control is required.
Controlflex Couplings
Ever-power Controlflex couplings are a three-part assembly with a balanced design comprised of two hubs joined to one or two center inserts called frogs. This design and style creates a light in weight low inertia adaptable coupling capable of speeds up to 25,000 RPM. Clamp design hubs are made with inches, metric, keyed, and keyless bores ranging from 1/8” to 1-1/2” and 3mm to 40mm for high customizability. The unique design and style of the frog concentrates forces onto its versatile limbs enabling low bearing loads safeguarding sensitive small bearings in applications such as for example encoders or tachometers. Controlflex couplings happen to be also electrically isolating since the hubs do not feel and frogs are made from acetal. They are produced by Schmidt-Kupplung in Germany and so are RoHS3 compliant.
Disc Couplings
Ever-power manufactured disc couplings have huge torque and torsional stiffness functions, are zero-backlash, have a balanced design, and may accommodate all kinds of misalignment. They are made in single disc styles for small installations and twice disc styles for larger misalignment capabilities. Ever-vitality disc couplings are comprised of two anodized metal hubs, stainless steel disc springs, and a center spacer (double disc simply) creating a lightweight low inertia coupling with the capacity of speeds up to 10,000 RPM. Hubs are produced with or without keyways in clamp and collection screw types with bore sizes ranging from 1/8″ to 1-1/4″ and 3mm to 32mm. They are generally used in high performance stepper servo devices 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 varieties of misalignment. The two lightweight aluminum hubs press fit onto an elastomeric middle spacer known as “the spider” allowing for constant zero-backlash operation. Ever-vitality zero-backlash jaw couplings have a balanced design for lowered vibration at speeds up to 8,000 RPM. Hubs are manufactured with or without keyways in clamp or arranged screw types with bore sizes ranging from 1/8″ to 1-1/4″ and 3mm to 32mm. Spiders can be found in three durometers allowing the user to complement coupling performance with system requirements. Zero-backlash jaw couplings are generally found in applications with large acceleration/deceleration curves where dampening and precise action control are required.
Oldham Couplings
Ever-power manufactured oldham couplings have a highly customizable three-piece style, are zero-backlash, and also have large parallel misalignment features. Two anodized metal hubs press match the mating slot machines of the guts disk enabling zero-backlash operation and low bearing loads. Ever-ability oldham couplings have a balanced design and style for reduced vibration at boosts to 4,500 RPM. Hubs are manufactured with or without keyways in clamp or established screw types with bore sizes ranging from 1/8″ to 1-1/4″ and 3mm to 30mm. Disks can be found in three supplies allowing the user to complement coupling performance with system requirements. They are generally found in stepper servo devices that require a higher parallel misalignment coupling.
Slit Couplings
Ever-electrical power slit couplings will be an alloy, one part configuration made to provide smooth transmitting of motion, substantial torsional stiffness, low bearing loads, and long life. The slot structure provides the best harmony between zero backlash, torsional stiffness and low bearing load. With two units of identical slot machines, 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 are a reliable one piece coupling design that methods the efficiency of a bellows coupling.
Rotating shaft-driven mechanical components are commonly used in all types of machinery that accomplish the various processes and functions of modern industry.
o Shaft misalignment will place stresses on shafts and related elements of the assembly such as bearings, which can lead to early failure of both.
o Shaft ends could be misaligned radially or angularly, exhibit axial displacement, or experience a combo of all three.
o Travel couplings works extremely well to compensate for shaft misalignment, if the misalignment can be an intentional or an unintentional portion of the design.

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

SERVO COUPLINGS
Servo couplings from Ever-power can be purchased in a multitude of styles, sizes, and materials to match differing software requirements. Choosing the right servo coupling could be a difficult process that involves many performance factors which include: shaft misalignment, RPM, space requirements, torque, and others. Matching a shaft coupling with these factors is crucial to system performance. Ever-power presents servo couplings in rigid, beam, bellows, curved jaw, disc, and oldham types making it possible for the user to select the coupling that finest fits their software. All Ever-vitality couplings happen to be zero-backlash and manufactured inside our Marlborough, MA factory.
Servo couplings can be found in lots of different attachment styles in addition to a vast array of sizes and elements to suite your specific application and/or customized requirements. Maintaining optimum system performance relies on effectively complementing a shaft coupling predicated on your unique performance and application requirements and expectations. At Helical, we have considered the guesswork out of picking the complete servo coupling for your application by factoring in significant part dynamics such as for example shaft misalignment, space requirements, torque, and RPM.
