Beam Couplings
Ever-power manufactured beam couplings have large angular misalignment features, are zero-backlash and have a balanced design for reduced vibration in boosts to 6,000 RPM. They are created from a single piece of aluminum or stainless with multiple pieces of spiral cuts to provide bigger stiffness and better all-around misalignment features than traditional sole beam couplings. Ever-power beam couplings can be found 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 movement control is desired.
Bellows Couplings
Ever-power produced bellows couplings have excessive torque and torsional stiffness functions, are zero-backlash, possess a balanced design, and will accommodate all forms of misalignment. They will be made up of two anodized light weight aluminum hubs and a stainless bellows making a light-weight low inertia coupling capable of boosts to 10,000 RPM. The thin wall structure of the stainless steel bellows can simply flex while staying rigid under torsional loads. Ever-power manufactures bellows couplings hubs with or without keyways in clamp or placed screw styles with in ., metric, and in . to metric bores ranging from 1/8″ to 1 1″ and 3mm to 25mm. They are commonly used in high performance stepper servo systems where precise movement control is required.
Controlflex Couplings
Ever-power Controlflex couplings certainly are a three-piece assembly with a balanced design made up of two hubs joined to one or two middle inserts called frogs. This design creates a light in weight low inertia flexible coupling capable of boosts to 25,000 RPM. Clamp design hubs are produced with inch, metric, keyed, and keyless bores which range 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 little bearings in applications such as encoders or tachometers. Controlflex couplings are also electrically isolating because the hubs do not feel and frogs are made from acetal. They will be created by Schmidt-Kupplung in Germany and so are RoHS3 compliant.
Disc Couplings
Ever-power manufactured disc couplings have substantial torque and torsional stiffness functions, are zero-backlash, have a balanced design, and may accommodate all forms of misalignment. They will be made in single disc types for small installations and twice disc styles for bigger misalignment capabilities. Ever-vitality disc couplings are comprised of two anodized light weight aluminum hubs, stainless steel disc springs, and a centre spacer (double disc simply) creating a lightweight low inertia coupling with the capacity of speeds up to 10,000 RPM. Hubs are made with or without keyways in clamp and set screw variations 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 action control is required.
Jaw Couplings
Ever-power made zero-backlash jaw couplings possess an extremely customizable three-piece style, have high dampening features, and can accommodate all types of misalignment. The two aluminum hubs press suit onto an elastomeric center spacer referred to as “the spider” enabling steady zero-backlash operation. Ever-electricity zero-backlash jaw couplings possess a balanced style for reduced vibration at boosts to 8,000 RPM. Hubs are created 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 32mm. Spiders can be purchased in three durometers permitting the user to complement coupling performance with system requirements. Zero-backlash jaw couplings are generally found in applications with substantial acceleration/deceleration curves where dampening and precise action control are required.
Oldham Couplings
Ever-power manufactured oldham couplings have a highly customizable three-piece style, are zero-backlash, and have excessive parallel misalignment features. Two anodized light weight aluminum hubs press match the mating slot machine games of the guts disk enabling zero-backlash procedure and low bearing loads. Ever-vitality oldham couplings have a balanced design and style for reduced vibration at speeds up to 4,500 RPM. Hubs are manufactured with or without keyways in clamp or established screw types with bore sizes ranging from 1/8″ to 1-1/4″ and 3mm to 30mm. Disks can be purchased in three components allowing the user to match coupling performance with system requirements. They are generally used in stepper servo systems that require a high parallel misalignment coupling.
Slit Couplings
Ever-ability slit couplings are an alloy, one piece configuration designed to provide smooth transmission of motion, great torsional stiffness, low bearing loads, and extended life. The slot structure provides the best harmony 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 boosts to 70,000 rpm, slit couplings certainly are a reliable one part coupling design that techniques the effectiveness of a bellows coupling.
Rotating shaft-driven mechanical pieces are commonly used in all kinds of machinery that execute the various processes and capabilities of modern industry.
o Shaft misalignment will place stresses on shafts and related elements of the assembly such as bearings, which can cause early inability of both.
o Shaft ends can be misaligned radially or angularly, exhibit axial displacement, or experience a combo of all three.
o Drive couplings can be utilised to pay for shaft misalignment, whether the misalignment is an intentional or an unintentional the main design.

Ever-powerdrive couplings will be power transmission parts used to couple the shafts of various mechanical devices, and compensate for shaft misalignment, reducing stress in shafts and bearings. Beam-style couplings are created for servo applications, giving the overall flexibility of bellows couplings plus torsional stiffness and strength of disc couplings.

SERVO COUPLINGS
Servo couplings from Ever-power can be found in a multitude of types, sizes, and supplies to match differing program requirements. Choosing the correct servo coupling can be a difficult procedure which involves many performance factors including: shaft misalignment, RPM, space requirements, torque, and others. Matching a shaft coupling with these factors is critical to system overall performance. Ever-power provides servo couplings in rigid, beam, bellows, curved jaw, disc, and oldham types allowing for the user to choose the coupling that best fits their app. All Ever-vitality couplings happen to be zero-backlash and manufactured in our Marlborough, MA factory.
Servo couplings are offered in many different attachment styles as well as a vast selection of sizes and products to suite your unique application and/or custom requirements. Maintaining optimum system performance relies on properly coordinating a shaft coupling based on your specific performance and program requirements and specifications. At Helical, we have taken the guesswork out of picking the complete servo coupling for your application by factoring in important aspect dynamics such as shaft misalignment, space requirements, torque, and RPM.
