SERVO COUPLINGS
Servo couplings from Ever-power can be found in a wide variety of styles, sizes, and elements to match differing app requirements. Choosing the right servo coupling could be a difficult process that involves many performance factors including: shaft misalignment, RPM, space requirements, torque, and others. Matching a shaft coupling with these factors 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 very best fits their software. All Ever-electric power couplings will be zero-backlash and manufactured in our Marlborough, MA factory.
Servo couplings can be found in many different attachment styles in addition to a vast selection of sizes and components to suite your specific application and/or customized requirements. Maintaining optimum system performance relies on properly coordinating a shaft coupling based on your specific performance and program requirements and benchmarks. At Helical, we’ve used the guesswork out of choosing the complete servo coupling for your application by factoring in vital element dynamics such as for example shaft misalignment, space requirements, torque, and RPM. Check out our coupling items.

Ever-powerdrive couplings will be power transmission elements used to few the shafts of varied mechanical devices, and also to compensate for shaft misalignment, reducing stress on shafts and bearings. Beam-style couplings are suitable for servo applications, supplying the versatility of bellows couplings plus torsional stiffness and power of disc couplings.

Beam Couplings
Ever-power produced beam couplings have large angular misalignment functions, are zero-backlash and have a balanced design for reduced vibration in boosts to 6,000 RPM. They are produced from a single little bit of aluminum or stainless with multiple models of spiral cuts to provide bigger stiffness and better all-around misalignment functions 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 light duty power transmitting applications where precise action control is desired.
Bellows Couplings
Ever-power manufactured bellows couplings have great torque and torsional stiffness capabilities, are zero-backlash, possess a balanced design, and can accommodate all types of misalignment. They happen to be comprised of two anodized light weight aluminum 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 bellows can easily flex while staying rigid under torsional loads. Ever-electrical power manufactures bellows couplings hubs with or without keyways in clamp or collection screw styles with “, metric, and inches to metric bores which range from 1/8″ to 1 1” and 3mm to 25mm. They are generally used in high performance 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 comprised of two hubs joined to one or two centre inserts called frogs. This design and style creates a light in weight low inertia adaptable coupling capable of boosts to 25,000 RPM. Clamp design hubs are produced with “, metric, keyed, and keyless bores ranging from 1/8” to 1-1/2” and 3mm to 40mm for excessive customizability. The unique design of the frog concentrates forces onto its versatile limbs enabling low bearing loads guarding sensitive little bearings in applications such as encoders or tachometers. Controlflex couplings will be also electrically isolating since the hubs do not feel and frogs are made of acetal. They will be manufactured 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, possess a balanced design, and will accommodate all kinds of misalignment. They are created in single disc designs for compact installations and twice disc styles for larger misalignment capabilities. Ever-ability disc couplings are comprised of two anodized light weight aluminum hubs, stainless steel disc springs, and a centre spacer (double disc simply) creating a light and portable low inertia coupling with the capacity of boosts to 10,000 RPM. Hubs are produced 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 commonly used in powerful stepper servo devices where precise action control is required.
Jaw Couplings
Ever-power produced zero-backlash jaw couplings have a highly customizable three-piece style, have high dampening functions, and can accommodate all types of misalignment. The two metal hubs press fit onto an elastomeric middle spacer known as “the spider” allowing for regular zero-backlash operation. Ever-power zero-backlash jaw couplings have a balanced design for reduced vibration at boosts to 8,000 RPM. Hubs are made 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 can be found in three durometers permitting the user to complement coupling performance with system requirements. Zero-backlash jaw couplings are commonly found in applications with substantial acceleration/deceleration curves where dampening and specific movement control are required.
Oldham Couplings
Ever-power manufactured oldham couplings have an extremely customizable three-piece style, are zero-backlash, and have huge parallel misalignment capacities. Two anodized aluminium hubs press fit into the mating slot machine games of the center disk enabling zero-backlash procedure and low bearing loads. Ever-power oldham couplings possess a balanced style for reduced vibration at boosts to 4,500 RPM. Hubs are manufactured with or without keyways in clamp or placed screw types with bore sizes which range from 1/8″ to 1-1/4″ and 3mm to 30mm. Disks can be found in three products 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 transmitting of motion, large torsional stiffness, low bearing loads, and extended life. The slot design provides the best equilibrium between zero backlash, torsional stiffness and low bearing load. With two pieces of identical slot machine games, the mini slit coupling is definitely 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 certainly are a reliable one part coupling design that methods the performance of a bellows coupling.
Rotating shaft-driven mechanical parts are commonly used in all types of machinery that execute the many processes and capabilities of modern industry.
o Shaft misalignment will place stresses on shafts and related parts of the assembly such as for example bearings, which can cause early inability of both.
o Shaft ends can be misaligned radially or angularly, exhibit axial displacement, or experience a mixture of all three.
o Drive couplings works extremely well to compensate for shaft misalignment, if the misalignment can be an intentional or an unintentional section of the design.
