SERVO COUPLINGS
Servo couplings from Ever-power can be found in a multitude of designs, sizes, and resources to match differing program requirements. Choosing the correct servo coupling could be a difficult method that involves many performance factors including: shaft misalignment, RPM, space requirements, torque, and others. Matching a shaft coupling with these elements is critical to system effectiveness. Ever-power offers servo couplings in rigid, beam, bellows, curved jaw, disc, and oldham types enabling the user to select the coupling that finest fits their application. All Ever-electrical power couplings happen to 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 materials to suite your specific application and/or customized requirements. Maintaining optimum system performance relies on effectively matching a shaft coupling based on your unique performance and request requirements and benchmarks. At Helical, we have used the guesswork out of selecting the complete servo coupling for your application by factoring in essential aspect dynamics such as shaft misalignment, space requirements, torque, and RPM.

Ever-powerdrive couplings happen to be power transmission pieces used to few the shafts of various mechanical devices, and also to compensate for shaft misalignment, reducing stress on shafts and bearings. Beam-style couplings are suitable for servo applications, giving the versatility of bellows couplings plus torsional stiffness and strength of disc couplings.

Beam Couplings
Ever-power produced beam couplings have great angular misalignment features, are zero-backlash and also have a balanced design for reduced vibration for boosts to 6,000 RPM. They are made from a single little bit of aluminum or stainless with multiple units of spiral cuts to supply higher stiffness and better all-around misalignment capabilities than traditional single beam couplings. Ever-electrical power beam couplings can be found in inch, metric, and inch to metric bore sizes which range from 3/32″ to 3/4″ and 3mm to 20mm. they are commonly used in encoder, tachometer, and light duty power transmitting applications where precise movement control is desired.
Bellows Couplings
Ever-power manufactured bellows couplings have large torque and torsional stiffness capacities, are zero-backlash, have a balanced design, and can accommodate all types of misalignment. They are made up of two anodized aluminum hubs and a stainless steel bellows making a lightweight low inertia coupling capable of boosts to 10,000 RPM. The thin wall structure of the stainless bellows can simply flex while leftover rigid under torsional loads. Ever-electricity manufactures bellows couplings hubs with or without keyways in clamp or establish screw styles with inch, metric, and inch to metric bores which range from 1/8″ to 1 1″ and 3mm to 25mm. They are generally used in powerful stepper servo systems where precise action control is required.
Controlflex Couplings
Ever-power Controlflex couplings certainly are a three-piece assembly with a balanced design and style made up of two hubs joined to one or two center inserts called frogs. This design and style creates a lightweight low inertia versatile coupling capable of boosts to 25,000 RPM. Clamp style hubs are produced with “, metric, keyed, and keyless bores ranging from 1/8” to 1-1/2” and 3mm to 40mm for substantial customizability. The unique design of the frog concentrates forces onto its versatile limbs enabling low bearing loads safeguarding sensitive tiny bearings in applications such as encoders or tachometers. Controlflex couplings happen to be also electrically isolating since the hubs do not feel and frogs are manufactured from acetal. They are produced by Schmidt-Kupplung in Germany and are RoHS3 compliant.
Disc Couplings
Ever-power produced disc couplings have excessive torque and torsional stiffness capacities, are zero-backlash, have a balanced design, and may accommodate all types of misalignment. They will be created in single disc types for compact installations and dual disc styles for higher misalignment capabilities. Ever-electrical power disc couplings are made up of two anodized lightweight aluminum hubs, stainless disc springs, and a center spacer (double disc only) creating a lightweight low inertia coupling capable of speeds up to 10,000 RPM. Hubs are created with or without keyways in clamp and set screw styles with bore sizes ranging from 1/8″ to 1-1/4″ and 3mm to 32mm. They are generally used in powerful stepper servo systems where precise motion control is required.
Jaw Couplings
Ever-power manufactured zero-backlash jaw couplings possess a highly customizable three-piece design, have high dampening functions, and may accommodate all forms of misalignment. The two metal hubs press match onto an elastomeric center spacer called “the spider” allowing for constant zero-backlash operation. Ever-power zero-backlash jaw couplings have a balanced design and style for lowered vibration at speeds up to 8,000 RPM. Hubs are made with or without keyways in clamp or establish screw types with bore sizes ranging from 1/8″ to 1-1/4″ and 3mm to 32mm. Spiders can be purchased in three durometers permitting the user to complement coupling performance with system requirements. Zero-backlash jaw couplings are commonly used in applications with high acceleration/deceleration curves where dampening and precise movement control are required.
Oldham Couplings
Ever-power produced oldham couplings have an extremely customizable three-piece design, are zero-backlash, and also have great parallel misalignment functions. Two anodized metal hubs press fit into the mating slots of the guts disk enabling zero-backlash procedure and low bearing loads. Ever-electrical power oldham couplings possess a balanced style for lowered vibration at speeds up to 4,500 RPM. Hubs are made with or without keyways in clamp or establish screw types with bore sizes ranging from 1/8″ to 1-1/4″ and 3mm to 30mm. Disks can be purchased in three supplies allowing the user to match coupling performance with system requirements. They are commonly used in stepper servo systems that require a high parallel misalignment coupling.
Slit Couplings
Ever-electrical power slit couplings happen to be an alloy, one piece configuration designed to provide smooth transmission of motion, substantial torsional stiffness, low bearing loads, and long life. The slot design provides the best harmony between zero backlash, torsional stiffness and low bearing load. With two units of identical slot machine games, the mini slit coupling can be constant velocity by style and handles angular, parallel and axial offset. Available in 6 and 8 mm diameters and allowable boosts to 70,000 rpm, slit couplings certainly are a reliable one piece coupling design that methods the effectiveness of a bellows coupling.
Rotating shaft-driven mechanical parts are commonly used in all forms of machinery that do the various processes and capabilities of modern industry.
o Shaft misalignment will place stresses on shafts and related parts of the assembly such as bearings, which can result in early failing of both.
o Shaft ends can be misaligned radially or 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 an unintentional area of the design.
