Servo coupling

SERVO COUPLINGS
Servo couplings from Ever-power are available in a wide variety of types, sizes, and components to match differing application requirements. Choosing the right servo coupling can be a difficult procedure which involves many performance elements which include: shaft misalignment, RPM, space requirements, torque, and others. Matching a shaft coupling with these factors is critical to system efficiency. Ever-power offers servo couplings in rigid, beam, bellows, curved jaw, disc, and oldham types permitting the user to select the coupling that finest fits their app. All Ever-ability couplings will be zero-backlash and manufactured in our Marlborough, MA factory.
Servo couplings are offered in many different attachment styles in addition to a vast selection of sizes and elements to suite your unique application and/or customized requirements. Maintaining optimum program performance relies on effectively matching a shaft coupling based on your unique performance and program requirements and requirements. At Helical, we’ve taken the guesswork out of selecting the complete servo coupling for your application by factoring in important element dynamics such as shaft misalignment, space requirements, torque, and RPM. Have a look at our coupling items.

Ever-powerdrive couplings are power transmission pieces used to couple the shafts of varied mechanical devices, also to compensate for shaft misalignment, reducing stress on shafts and bearings. Beam-style couplings are designed for servo applications, giving the flexibility of bellows couplings plus torsional stiffness and strength of disc couplings.

Beam Couplings
Ever-power made beam couplings have huge angular misalignment capacities, are zero-backlash and have a balanced style for reduced vibration in boosts to 6,000 RPM. They are produced from a single piece of aluminum or stainless with multiple pieces of spiral cuts to provide bigger stiffness and better all-around misalignment capacities than traditional single beam couplings. Ever-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 found in encoder, tachometer, and light duty power transmission applications where precise movement control is desired.
Bellows Couplings
Ever-power created bellows couplings have substantial torque and torsional stiffness capacities, are zero-backlash, have a balanced design, and will accommodate all types of misalignment. They happen to be comprised of two anodized metal hubs and a stainless steel bellows making a compact low inertia coupling capable of speeds up to 10,000 RPM. The thin wall of the stainless steel bellows can simply flex while leftover rigid under torsional loads. Ever-vitality manufactures bellows couplings hubs with or without keyways in clamp or set screw styles with in ., metric, and in . to metric bores ranging from 1/8″ to at least one 1″ and 3mm to 25mm. They are generally used in high performance stepper servo systems where precise motion control is required.
Controlflex Couplings
Ever-power Controlflex couplings are a three-part assembly with a balanced design and style made up of two hubs joined to one or two center inserts called frogs. This design creates a lightweight low inertia flexible coupling capable of boosts to 25,000 RPM. Clamp design hubs are manufactured with in ., metric, keyed, and keyless bores which range from 1/8” to 1-1/2” and 3mm to 40mm for huge customizability. The unique design of the frog concentrates forces onto its flexible limbs allowing for low bearing loads guarding sensitive little bearings in applications such as for example encoders or tachometers. Controlflex couplings will be also electrically isolating since the hubs do not touch and frogs are made of acetal. They are manufactured by Schmidt-Kupplung in Germany and so are RoHS3 compliant.
Disc Couplings
Ever-power manufactured disc couplings have substantial torque and torsional stiffness capabilities, are zero-backlash, have a balanced design, and will accommodate all varieties of misalignment. They will be made in single disc variations for compact installations and twice disc styles for higher misalignment capabilities. Ever-ability disc couplings are comprised of two anodized aluminium hubs, stainless steel disc springs, and a center spacer (double disc simply) creating a light-weight low inertia coupling capable of boosts to 10,000 RPM. Hubs are produced with or without keyways in clamp and collection screw variations with bore sizes which range from 1/8″ to 1-1/4″ and 3mm to 32mm. They are generally used in high performance stepper servo systems where precise movement control is required.
Jaw Couplings
Ever-power made zero-backlash jaw couplings possess a highly customizable three-piece style, have high dampening features, and will accommodate all types of misalignment. The two light weight aluminum hubs press in shape onto an elastomeric center spacer named “the spider” allowing for constant zero-backlash operation. Ever-electric power zero-backlash jaw couplings have a balanced style for reduced vibration at boosts 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 can be purchased in three durometers allowing the user to match coupling performance with system requirements. Zero-backlash jaw couplings are commonly found in applications with large acceleration/deceleration curves where dampening and specific movement control are required.
Oldham Couplings
Ever-power produced oldham couplings have a highly customizable three-piece style, are zero-backlash, and have large parallel misalignment functions. Two anodized lightweight aluminum hubs press fit into the mating slot machines of the center disk enabling zero-backlash operation and low bearing loads. Ever-vitality oldham couplings have a balanced style for reduced vibration at speeds up to 4,500 RPM. Hubs are manufactured with or without keyways in clamp or set screw types with bore sizes which range from 1/8″ to 1-1/4″ and 3mm to 30mm. Disks can be found in three supplies allowing the user to match coupling performance with program requirements. They are generally found in stepper servo systems that require a higher parallel misalignment coupling.
Slit Couplings
Ever-vitality slit couplings happen to be an alloy, one piece configuration designed to provide smooth tranny of motion, huge torsional stiffness, low bearing loads, and extended life. The slot pattern provides the best stability between zero backlash, torsional stiffness and low bearing load. With two sets of identical slot machine games, the mini slit coupling is constant velocity by design and handles angular, parallel and axial offset. Obtainable in 6 and 8 mm diameters and allowable speeds up to 70,000 rpm, slit couplings are a reliable one part coupling design that methods the functionality of a bellows coupling.
Rotating shaft-driven mechanical elements are commonly found in all kinds of machinery that execute the various processes and features of modern industry.
o Shaft misalignment will place stresses on shafts and related parts of the assembly such as bearings, which can lead to early failing of both.
o Shaft ends could be misaligned radially or perhaps angularly, exhibit axial displacement, or experience a blend of all three.
o Drive couplings can be utilized to compensate for shaft misalignment, if the misalignment can be an intentional or perhaps an unintentional the main design.
