Servo couplings from Ever-power can be purchased in a wide variety of types, sizes, and supplies to match differing app requirements. Choosing the correct servo coupling could be a difficult method which 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 provides servo couplings in rigid, beam, bellows, curved jaw, disc, and oldham types permitting the user to select the coupling that ideal fits their application. 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 array of sizes and products to suite your specific application and/or custom requirements. Maintaining optimum program performance relies on correctly matching a shaft coupling predicated on your unique performance and request requirements and standards. At Helical, we’ve considered 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. Have a look at our coupling goods.

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

Beam Couplings
Ever-power created beam couplings have high angular misalignment capabilities, are zero-backlash and also have a balanced style for reduced vibration for speeds up to 6,000 RPM. They are created from a single piece of aluminum or stainless with multiple units of spiral cuts to provide bigger stiffness and better all-around misalignment capacities than traditional sole beam couplings. Ever-electric power beam couplings are available in inch, metric, and inch to metric bore sizes ranging 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 motion control is desired.
Bellows Couplings
Ever-power made bellows couplings have high 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 bellows making a light low inertia coupling capable of speeds up to 10,000 RPM. The thin wall structure of the stainless steel bellows can easily flex while leftover rigid under torsional loads. Ever-ability manufactures bellows couplings hubs with or without keyways in clamp or established screw styles with in ., metric, and inch to metric bores which range from 1/8″ to 1 1″ and 3mm to 25mm. They are generally used in high performance stepper servo systems where precise action control is required.
Controlflex Couplings
Ever-power Controlflex couplings are a three-piece assembly with a balanced design made up of two hubs joined to one or two center inserts called frogs. This design creates a light and portable low inertia versatile coupling capable of boosts to 25,000 RPM. Clamp style hubs are created with inches, metric, keyed, and keyless bores which range from 1/8” to 1-1/2” and 3mm to 40mm for high customizability. The unique design of the frog concentrates forces onto its versatile limbs enabling low bearing loads guarding sensitive small bearings in applications such as encoders or tachometers. Controlflex couplings are also electrically isolating because the hubs do not feel and frogs are manufactured from acetal. They happen to be manufactured by Schmidt-Kupplung in Germany and are RoHS3 compliant.
Disc Couplings
Ever-power created disc couplings have substantial torque and torsional stiffness functions, are zero-backlash, possess a balanced design, and may accommodate all kinds of misalignment. They will be manufactured in single disc designs for small installations and double disc styles for higher misalignment capabilities. Ever-electricity disc couplings are made up of two anodized lightweight aluminum hubs, stainless steel disc springs, and a centre spacer (double disc only) 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 establish screw models with bore sizes which range from 1/8″ to 1-1/4″ and 3mm to 32mm. They are generally used in powerful stepper servo systems where precise movement control is required.
Jaw Couplings
Ever-power produced zero-backlash jaw couplings have an extremely customizable three-piece design, have high dampening capabilities, and may accommodate all types of misalignment. The two light weight aluminum hubs press match onto an elastomeric middle spacer named “the spider” allowing for steady zero-backlash operation. Ever-electricity zero-backlash jaw couplings possess a balanced design and style for reduced vibration at boosts to 8,000 RPM. Hubs are manufactured 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 are available in three durometers permitting the user to complement coupling performance with system requirements. Zero-backlash jaw couplings are generally used in applications with excessive acceleration/deceleration curves where dampening and exact motion control are required.
Oldham Couplings
Ever-power manufactured oldham couplings have an extremely customizable three-piece design, are zero-backlash, and have large parallel misalignment capabilities. Two anodized lightweight aluminum hubs press match the mating slot machine games of the guts disk enabling zero-backlash operation and low bearing loads. Ever-electricity oldham couplings possess a balanced design for decreased vibration at boosts to 4,500 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 30mm. Disks can be purchased in three components allowing the user to complement coupling performance with system requirements. They are commonly found in stepper servo devices that require a high parallel misalignment coupling.
Slit Couplings
Ever-ability slit couplings happen to be an alloy, one piece configuration designed to provide smooth transmitting of motion, huge torsional stiffness, low bearing loads, and long life. The slot routine provides the best harmony between zero backlash, torsional stiffness and low bearing load. With two sets 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 speeds up to 70,000 rpm, slit couplings certainly are a reliable one piece coupling design that techniques the effectiveness of a bellows coupling.
Rotating shaft-driven mechanical pieces are commonly used in all varieties 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 bearings, which can lead to early inability of both.
o Shaft ends can be misaligned radially or angularly, exhibit axial displacement, or experience a combination of all three.
o Drive couplings can be utilised to pay for shaft misalignment, whether the misalignment is an intentional or perhaps an unintentional part of the design.
