Beam Couplings
Ever-power created beam couplings have huge angular misalignment capabilities, are zero-backlash and have a balanced style for reduced vibration at boosts to 6,000 RPM. They are made from a single piece of aluminum or stainless steel with multiple units of spiral cuts to supply larger stiffness and better all-around misalignment capacities than traditional sole beam couplings. Ever-ability beam couplings are available in inch, metric, and inch to metric bore sizes which range from 3/32″ to 3/4″ and 3mm to 20mm. they are generally found in encoder, tachometer, and light duty power transmission applications where precise movement control is desired.
Bellows Couplings
Ever-power manufactured bellows couplings have substantial torque and torsional stiffness features, are zero-backlash, have a balanced design, and may accommodate all varieties of misalignment. They are made up of two anodized aluminium hubs and a stainless steel bellows making a compact low inertia coupling with the capacity of speeds up to 10,000 RPM. The thin wall of the stainless steel bellows can simply flex while leftover rigid under torsional loads. Ever-ability manufactures bellows couplings hubs with or without keyways in clamp or established screw styles with inch, metric, and in . to metric bores ranging 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 certainly are a three-part assembly with a balanced design and style comprised of two hubs joined to one or two center inserts called frogs. This design creates a light and portable low inertia adaptable coupling capable of boosts to 25,000 RPM. Clamp style hubs are manufactured with inch, 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 allowing for low bearing loads protecting sensitive small bearings in applications such as for example encoders or tachometers. Controlflex couplings happen to be also electrically isolating since the hubs do not contact and frogs are made of acetal. They are made by Schmidt-Kupplung in Germany and are RoHS3 compliant.
Disc Couplings
Ever-power made disc couplings have high torque and torsional stiffness functions, are zero-backlash, have a balanced design, and can accommodate all forms of misalignment. They will be manufactured in single disc variations for compact installations and dual disc styles for larger misalignment capabilities. Ever-electricity disc couplings are made up of two anodized aluminum hubs, stainless steel disc springs, and a middle spacer (double disc just) creating a light in weight low inertia coupling capable of speeds up to 10,000 RPM. Hubs are made with or without keyways in clamp and placed screw designs with bore sizes ranging from 1/8″ to 1-1/4″ and 3mm to 32mm. They are generally used in high performance stepper servo devices where precise movement control is required.
Jaw Couplings
Ever-power produced zero-backlash jaw couplings have a highly customizable three-piece design, have high dampening capabilities, and can accommodate all types of misalignment. The two lightweight aluminum hubs press fit onto an elastomeric center spacer referred to as “the spider” allowing for constant zero-backlash operation. Ever-electrical power zero-backlash jaw couplings possess a balanced design for lowered vibration at boosts to 8,000 RPM. Hubs are produced with or without keyways in clamp or arranged screw types with bore sizes which range from 1/8″ to 1-1/4″ and 3mm to 32mm. Spiders can be found in three durometers allowing the user to complement coupling performance with program 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 created oldham couplings have a highly customizable three-piece style, are zero-backlash, and also have excessive parallel misalignment capabilities. Two anodized aluminium hubs press match the mating slot machines of the center disk allowing for zero-backlash procedure and low bearing loads. Ever-electricity oldham couplings possess a balanced style for lowered vibration at boosts to 4,500 RPM. Hubs are created with or without keyways in clamp or set screw types with bore sizes ranging from 1/8″ to 1-1/4″ and 3mm to 30mm. Disks can be found in three products allowing the user to complement coupling performance with system requirements. They are generally used 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 transmission of motion, great torsional stiffness, low bearing loads, and extended life. The slot style provides the best equilibrium between zero backlash, torsional stiffness and low bearing load. With two models of identical slot machines, the mini slit coupling is usually constant velocity by design and handles angular, parallel and axial offset. Available in 6 and 8 mm diameters and allowable boosts to 70,000 rpm, slit couplings are a reliable one part coupling design that methods the functionality of a bellows coupling.
Rotating shaft-driven mechanical elements are commonly found in all kinds of machinery that perform the many processes and capabilities of modern industry.
o Shaft misalignment will place stresses on shafts and related elements of the assembly such as for example bearings, which can bring about early failing of both.
o Shaft ends could be misaligned radially or angularly, exhibit axial displacement, or experience a blend of all three.
o Travel couplings can be utilized to compensate for shaft misalignment, if the misalignment is an intentional or an unintentional portion of the design.

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

Servo couplings from Ever-power can be found in a multitude of models, sizes, and materials to match differing software requirements. Choosing the right servo coupling can be a difficult procedure that involves many performance factors which include: shaft misalignment, RPM, space requirements, torque, and others. Matching a shaft coupling with these elements is crucial to system effectiveness. Ever-power offers servo couplings in rigid, beam, bellows, curved jaw, disc, and oldham types allowing for the user to choose the coupling that ideal fits their software. All Ever-electricity couplings will be zero-backlash and manufactured inside our Marlborough, MA factory.
Servo couplings can be found in lots of different attachment styles in addition to a vast array of sizes and elements to suite your specific application and/or custom requirements. Maintaining optimum program performance relies on effectively matching a shaft coupling predicated on your unique performance and application requirements and specifications. At Helical, we’ve taken the guesswork out of picking the complete servo coupling for your application by factoring in essential element dynamics such as for example shaft misalignment, space requirements, torque, and RPM.
