SERVO COUPLINGS
Servo couplings from Ever-power can be found in a multitude of designs, sizes, and supplies to match differing app requirements. Choosing the right servo coupling could be a difficult process that involves many performance factors including: shaft misalignment, RPM, space requirements, torque, and others. Matching a shaft coupling with these factors is crucial to system performance. Ever-power offers servo couplings in rigid, beam, bellows, curved jaw, disc, and oldham types enabling the user to select the coupling that best fits their software. All Ever-electrical power couplings are zero-backlash and manufactured in our Marlborough, MA factory.
Servo couplings can be found in many different attachment styles in addition to a vast selection of sizes and components to suite your specific application and/or custom requirements. Maintaining optimum system performance relies on properly coordinating a shaft coupling predicated on your specific performance and software requirements and standards. At Helical, we have used the guesswork out of picking the complete servo coupling for your application by factoring in significant element dynamics such as for example shaft misalignment, space requirements, torque, and RPM. Check out our coupling items.

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

Beam Couplings
Ever-power produced beam couplings have high angular misalignment features, 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 models of spiral cuts to provide bigger stiffness and better all-around misalignment functions than traditional one beam couplings. Ever-ability beam couplings can be purchased in inch, metric, and inch to metric bore sizes which range from 3/32″ to 3/4″ and 3mm to 20mm. they are generally used in encoder, tachometer, and light duty power tranny applications where precise motion control is desired.
Bellows Couplings
Ever-power manufactured bellows couplings have excessive torque and torsional stiffness capabilities, are zero-backlash, possess a balanced design, and can accommodate all types of misalignment. They happen to be made up of two anodized light weight aluminum hubs and a stainless steel bellows making a light in weight low inertia coupling with the capacity of speeds up to 10,000 RPM. The thin wall structure of the stainless steel bellows can easily flex while remaining rigid under torsional loads. Ever-electrical power manufactures bellows couplings hubs with or without keyways in clamp or established screw styles with “, metric, and inch to metric bores ranging from 1/8″ to 1 1” and 3mm to 25mm. They are commonly used in high performance stepper servo devices where precise motion control is required.
Controlflex Couplings
Ever-power Controlflex couplings certainly are a three-part assembly with a balanced style comprised of two hubs joined to one or two middle inserts called frogs. This design and style creates a light in weight low inertia adaptable coupling capable of boosts to 25,000 RPM. Clamp design 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 style of the frog concentrates forces onto its adaptable limbs enabling low bearing loads guarding sensitive tiny bearings in applications such as encoders or tachometers. Controlflex couplings will be also electrically isolating since the hubs do not touch and frogs are produced from acetal. They happen to be manufactured by Schmidt-Kupplung in Germany and so are RoHS3 compliant.
Disc Couplings
Ever-power created disc couplings have high torque and torsional stiffness capabilities, are zero-backlash, possess a balanced design, and will accommodate all kinds of misalignment. They will be created in single disc designs for compact installations and twice disc styles for larger misalignment capabilities. Ever-ability disc couplings are made up of two anodized lightweight aluminum hubs, stainless steel disc springs, and a middle spacer (double disc simply) creating a light in weight low inertia coupling capable of speeds up to 10,000 RPM. Hubs are produced with or without keyways in clamp and establish screw designs with bore sizes ranging from 1/8″ to 1-1/4″ and 3mm to 32mm. They are commonly used in high performance stepper servo devices where precise action control is required.
Jaw Couplings
Ever-power produced zero-backlash jaw couplings have a highly customizable three-piece style, have high dampening functions, and can accommodate all types of misalignment. The two metal hubs press match onto an elastomeric middle spacer referred to as “the spider” allowing for regular zero-backlash operation. Ever-power zero-backlash jaw couplings have a balanced design for reduced vibration at boosts to 8,000 RPM. Hubs are created with or without keyways in clamp or establish screw types with bore sizes which range from 1/8″ to 1-1/4″ and 3mm to 32mm. Spiders can be purchased in three durometers enabling the user to match coupling performance with system requirements. Zero-backlash jaw couplings are commonly used in applications with substantial acceleration/deceleration curves where dampening and specific movement control are required.
Oldham Couplings
Ever-power produced oldham couplings have an extremely customizable three-piece design, are zero-backlash, and have huge parallel misalignment capabilities. Two anodized aluminium hubs press fit into the mating slot machine games of the center disk enabling zero-backlash procedure and low bearing loads. Ever-electrical power oldham couplings have a balanced style for reduced vibration at boosts to 4,500 RPM. Hubs are manufactured with or without keyways in clamp or collection screw types with bore sizes which range from 1/8″ to 1-1/4″ and 3mm to 30mm. Disks can be found in three products allowing the user to match coupling performance with system requirements. They are commonly used in stepper servo devices that require a high parallel misalignment coupling.
Slit Couplings
Ever-electric power slit couplings will be an alloy, one piece configuration made to provide smooth transmitting of motion, large torsional stiffness, low bearing loads, and long life. The slot routine provides the best equilibrium between zero backlash, torsional stiffness and low bearing load. With two sets 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 speeds up to 70,000 rpm, slit couplings certainly are a reliable one part coupling design that methods the overall performance of a bellows coupling.
Rotating shaft-driven mechanical components are commonly used in all forms of machinery that carry out the many 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 angularly, exhibit axial displacement, or experience a combination of all three.
o Drive couplings works extremely well to compensate for shaft misalignment, if the misalignment can be an intentional or an unintentional part of the design.
