Beam Couplings
Ever-power made beam couplings have excessive angular misalignment capabilities, are zero-backlash and have a balanced design for reduced vibration by speeds up to 6,000 RPM. They are created from a single little bit of aluminum or stainless steel with multiple units of spiral cuts to supply bigger stiffness and better all-around misalignment capabilities than traditional single beam couplings. Ever-power 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 generally found in encoder, tachometer, and mild duty power transmission applications where precise action control is desired.
Bellows Couplings
Ever-power produced bellows couplings have high torque and torsional stiffness capacities, are zero-backlash, have a balanced design, and may accommodate all forms of misalignment. They are made up of two anodized metal hubs and a stainless steel bellows making a light and portable low inertia coupling with the capacity of speeds up to 10,000 RPM. The thin wall structure of the stainless steel bellows may easily flex while remaining rigid under torsional loads. Ever-electrical power manufactures bellows couplings hubs with or without keyways in clamp or set screw styles with inch, metric, and inches to metric bores ranging from 1/8" to 1 1" and 3mm to 25mm. They are generally used in high performance stepper servo devices where precise action control is required.
Controlflex Couplings
Ever-power Controlflex couplings certainly are a three-part assembly with a balanced design comprised of two hubs joined to 1 or two middle inserts called frogs. This design and style creates a light-weight low inertia adaptable coupling capable of speeds up to 25,000 RPM. Clamp design hubs are produced with in ., metric, keyed, and keyless bores which range from 1/8” to 1-1/2” and 3mm to 40mm for high customizability. The unique design and style of the frog concentrates forces onto its versatile limbs allowing for low bearing loads safeguarding sensitive small bearings in applications such as encoders or tachometers. Controlflex couplings are also electrically isolating because the hubs do not touch and frogs are produced from acetal. They are created by Schmidt-Kupplung in Germany and are RoHS3 compliant.
Disc Couplings
Ever-power produced disc couplings have substantial torque and torsional stiffness capabilities, are zero-backlash, possess a balanced design, and can accommodate all varieties of misalignment. They will be produced in single disc designs for small installations and dual disc styles for higher misalignment capabilities. Ever-electricity disc couplings are made up of two anodized light weight aluminum hubs, stainless steel disc springs, and a center spacer (double disc simply) creating a light low inertia coupling with the capacity of speeds up to 10,000 RPM. Hubs are produced with or without keyways in clamp and set screw designs with bore sizes ranging from 1/8" to 1-1/4" and 3mm to 32mm. They are commonly used in powerful stepper servo systems where precise movement control is required.
Jaw Couplings
Ever-power manufactured zero-backlash jaw couplings possess an extremely customizable three-piece style, have high dampening features, and will accommodate all varieties of misalignment. The two metal hubs press fit onto an elastomeric center spacer known as "the spider" enabling regular zero-backlash operation. Ever-power zero-backlash jaw couplings have a balanced design for lowered vibration at speeds up to 8,000 RPM. Hubs are produced with or without keyways in clamp or placed screw types with bore sizes ranging from 1/8" to 1-1/4" and 3mm to 32mm. Spiders are available in three durometers enabling the user to match coupling performance with program requirements. Zero-backlash jaw couplings are generally found in applications with great acceleration/deceleration curves where dampening and exact motion control are required.
Oldham Couplings
Ever-power produced oldham couplings have a highly customizable three-piece design, are zero-backlash, and have excessive parallel misalignment functions. Two anodized lightweight aluminum hubs press match the mating slots of the center disk allowing for zero-backlash procedure and low bearing loads. Ever-electricity oldham couplings possess a balanced design and style for decreased 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 purchased in three supplies allowing the user to match coupling performance with program requirements. They are commonly used in stepper servo devices that require a high parallel misalignment coupling.
Slit Couplings
Ever-electricity slit couplings will be an alloy, one piece configuration made to provide smooth tranny 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 units of identical slot machine games, the mini slit coupling is usually 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 part coupling design that approaches the effectiveness of a bellows coupling.
Rotating shaft-driven mechanical components are commonly found in all kinds of machinery that perform the various processes and capabilities 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 failure of both.
o Shaft ends could be misaligned radially or perhaps angularly, exhibit axial displacement, or experience a combo of all three.
o Travel couplings can be used to compensate for shaft misalignment, if the misalignment can be an intentional or an unintentional area of the design.

Ever-powerdrive couplings are power transmission components used to couple the shafts of varied mechanical devices, and to compensate for shaft misalignment, reducing stress in shafts and bearings. Beam-style couplings are suitable for servo applications, offering the versatility of bellows couplings plus torsional stiffness and durability of disc couplings.

Servo couplings from Ever-power are available in a wide variety of models, sizes, and products to match differing software requirements. Choosing the right servo coupling can be a difficult method that involves many performance elements which include: shaft misalignment, RPM, space requirements, torque, and others. Matching a shaft coupling with these elements is critical to system effectiveness. Ever-power provides servo couplings in rigid, beam, bellows, curved jaw, disc, and oldham types allowing the user to select the coupling that greatest fits their software. All Ever-electricity 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 resources to suite your specific application and/or custom requirements. Maintaining optimum system performance relies on properly coordinating a shaft coupling predicated on your unique performance and application requirements and standards. At Helical, we have considered the guesswork out of selecting the complete servo coupling for the application by factoring in critical element dynamics such as for example shaft misalignment, space requirements, torque, and RPM.
