SERVO COUPLINGS
Servo couplings from Ever-power can be purchased in a multitude of variations, sizes, and materials to match differing program requirements. Choosing the right servo coupling could be a difficult process which involves many performance elements which includes: shaft misalignment, RPM, space requirements, torque, and others. Matching a shaft coupling with these factors is crucial to system overall performance. Ever-power offers servo couplings in rigid, beam, bellows, curved jaw, disc, and oldham types allowing for the user to select the coupling that ideal fits their program. All Ever-electricity couplings are zero-backlash and manufactured inside our Marlborough, MA factory.
Servo couplings can be found in lots of different attachment styles as well as a vast selection of sizes and supplies to suite your unique application and/or custom requirements. Maintaining optimum system performance relies on properly matching a shaft coupling predicated on your unique performance and software requirements and standards. At Helical, we have considered the guesswork out of choosing the precise servo coupling for your application by factoring in vital component dynamics such as shaft misalignment, space requirements, torque, and RPM.

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

Beam Couplings
Ever-power produced beam couplings have high angular misalignment functions, are zero-backlash and also have a balanced design for reduced vibration by 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 higher stiffness and better all-around misalignment features than traditional solitary beam couplings. Ever-electricity 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 commonly used in encoder, tachometer, and mild duty power transmission applications where precise action control is desired.
Bellows Couplings
Ever-power produced bellows couplings have excessive torque and torsional stiffness capabilities, are zero-backlash, have a balanced design, and may accommodate all varieties of misalignment. They will be comprised 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 of the stainless steel bellows can simply flex while staying rigid under torsional loads. Ever-vitality manufactures bellows couplings hubs with or without keyways in clamp or arranged screw styles with inch, metric, and inch to metric bores which range from 1/8″ to 1 1″ and 3mm to 25mm. They are commonly used in powerful stepper servo devices where precise motion control is required.
Controlflex Couplings
Ever-power Controlflex couplings are a three-piece assembly with a balanced design comprised of two hubs joined to one or two middle inserts called frogs. This design creates a light-weight low inertia adaptable coupling capable of boosts to 25,000 RPM. Clamp style hubs are made with inches, metric, keyed, and keyless bores ranging from 1/8” to 1-1/2” and 3mm to 40mm for great customizability. The unique style of the frog concentrates forces onto its adaptable limbs allowing for low bearing loads safeguarding sensitive small bearings in applications such as encoders or tachometers. Controlflex couplings are also electrically isolating since the hubs do not touch and frogs are made of acetal. They will be made by Schmidt-Kupplung in Germany and so are RoHS3 compliant.
Disc Couplings
Ever-power made disc couplings have huge torque and torsional stiffness capabilities, are zero-backlash, have a balanced design, and may accommodate all kinds of misalignment. They happen to be produced in single disc types for small installations and twice disc styles for larger misalignment capabilities. Ever-electricity disc couplings are made up of two anodized aluminum hubs, stainless disc springs, and a middle spacer (double disc just) creating a light low inertia coupling capable of speeds up to 10,000 RPM. Hubs are manufactured with or without keyways in clamp and set screw designs with bore sizes which range from 1/8″ to 1-1/4″ and 3mm to 32mm. They are commonly used in high performance 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 capacities, and may accommodate all kinds of misalignment. The two aluminium hubs press suit onto an elastomeric middle spacer known as “the spider” enabling regular zero-backlash operation. Ever-electric power zero-backlash jaw couplings have a balanced design for lowered vibration at speeds up to 8,000 RPM. Hubs are created 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 are available in three durometers permitting the user to match coupling performance with system requirements. Zero-backlash jaw couplings are generally found in applications with substantial acceleration/deceleration curves where dampening and exact action control are required.
Oldham Couplings
Ever-power made oldham couplings have a highly customizable three-piece design, are zero-backlash, and also have high parallel misalignment capacities. Two anodized aluminium hubs press fit into the mating slot machines of the guts disk allowing for zero-backlash operation and low bearing loads. Ever-electric power oldham couplings have a balanced design and style for reduced vibration at boosts to 4,500 RPM. Hubs are created with or without keyways in clamp or arranged screw types with bore sizes ranging from 1/8″ to 1-1/4″ and 3mm to 30mm. Disks can be purchased in three elements allowing the user to complement coupling performance with program requirements. They are generally found in stepper servo devices that require a high parallel misalignment coupling.
Slit Couplings
Ever-electricity slit couplings are an alloy, one piece configuration designed to provide smooth tranny of motion, great torsional stiffness, low bearing loads, and extended life. The slot style provides the best balance between zero backlash, torsional stiffness and low bearing load. With two units of identical slots, the mini slit coupling is normally constant velocity by style 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 part coupling design that techniques the performance of a bellows coupling.
Rotating shaft-driven mechanical elements are commonly found in all kinds 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 lead to early inability of both.
o Shaft ends can be misaligned radially or perhaps angularly, exhibit axial displacement, or experience a combination of all three.
o Travel couplings can be utilised to pay for shaft misalignment, whether the misalignment can be an intentional or an unintentional the main design.
