SERVO COUPLINGS
Servo couplings from Ever-power are available in a multitude of designs, sizes, and supplies to match differing request requirements. Choosing the correct servo coupling could be a difficult procedure which involves many performance elements including: shaft misalignment, RPM, space requirements, torque, and others. Matching a shaft coupling with these elements is critical to system performance. Ever-power presents servo couplings in rigid, beam, bellows, curved jaw, disc, and oldham types allowing the user to select the coupling that ideal fits their application. All Ever-vitality couplings are zero-backlash and manufactured inside our Marlborough, MA factory.
Servo couplings are offered in many different attachment styles as well as a vast selection of sizes and materials to suite your specific application and/or custom requirements. Maintaining optimum system performance relies on effectively complementing a shaft coupling predicated on your unique performance and application requirements and specifications. At Helical, we’ve considered the guesswork out of selecting the complete servo coupling for the application by factoring in significant aspect dynamics such as for example shaft misalignment, space requirements, torque, and RPM. Have a look at our coupling products.

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

Beam Couplings
Ever-power created beam couplings have high angular misalignment capabilities, are zero-backlash and have a balanced design for reduced vibration by boosts to 6,000 RPM. They are produced from a single piece of aluminum or stainless steel with multiple sets of spiral cuts to supply bigger stiffness and better all-around misalignment features than traditional single beam couplings. Ever-vitality 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 commonly found in encoder, tachometer, and lumination duty power transmission applications where precise movement control is desired.
Bellows Couplings
Ever-power created bellows couplings have huge torque and torsional stiffness capabilities, are zero-backlash, possess a balanced design, and can accommodate all varieties of misalignment. They will be made up of two anodized light weight aluminum hubs and a stainless steel bellows making a lightweight low inertia coupling with the capacity of speeds up to 10,000 RPM. The thin wall of the stainless bellows can easily flex while leftover rigid under torsional loads. Ever-power manufactures bellows couplings hubs with or without keyways in clamp or set screw styles with inches, 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 motion control is required.
Controlflex Couplings
Ever-power Controlflex couplings certainly are a three-piece assembly with a balanced design comprised of two hubs joined to one or two centre inserts called frogs. This design creates a light-weight low inertia versatile coupling capable of speeds up to 25,000 RPM. Clamp design hubs are made with “, 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 enabling low bearing loads guarding sensitive small bearings in applications such as for example encoders or tachometers. Controlflex couplings will be also electrically isolating because the hubs do not contact and frogs are manufactured from acetal. They happen to be created by Schmidt-Kupplung in Germany and so are RoHS3 compliant.
Disc Couplings
Ever-power produced disc couplings have large torque and torsional stiffness features, are zero-backlash, have a balanced design, and may accommodate all forms of misalignment. They happen to be manufactured in single disc variations for compact installations and twice disc styles for higher misalignment capabilities. Ever-electrical power disc couplings are comprised of two anodized aluminum hubs, stainless disc springs, and a center spacer (double disc simply) creating a light and portable low inertia coupling capable of speeds up to 10,000 RPM. Hubs are made with or without keyways in clamp and established screw designs with bore sizes which range from 1/8″ to 1-1/4″ and 3mm to 32mm. They are generally used in high performance stepper servo systems where precise motion control is required.
Jaw Couplings
Ever-power created zero-backlash jaw couplings have an extremely customizable three-piece design, have high dampening features, and will accommodate all types of misalignment. The two aluminum hubs press fit onto an elastomeric middle spacer known as “the spider” allowing for consistent zero-backlash operation. Ever-electricity zero-backlash jaw couplings possess a balanced design and style for decreased vibration at boosts to 8,000 RPM. Hubs are created with or without keyways in clamp or establish 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 complement coupling performance with program requirements. Zero-backlash jaw couplings are commonly used in applications with large acceleration/deceleration curves where dampening and specific motion control are required.
Oldham Couplings
Ever-power produced oldham couplings have an extremely customizable three-piece design, are zero-backlash, and have huge parallel misalignment features. Two anodized lightweight aluminum hubs press match the mating slot machines of the guts disk allowing for zero-backlash operation and low bearing loads. Ever-electric power oldham couplings possess a balanced design for reduced vibration at boosts to 4,500 RPM. Hubs are made 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 30mm. Disks can be purchased in three components allowing the user to match coupling performance with program requirements. They are commonly found in stepper servo devices that require a high parallel misalignment coupling.
Slit Couplings
Ever-electricity slit couplings happen to be an alloy, one piece configuration designed to provide smooth transmitting of motion, substantial torsional stiffness, low bearing loads, and long life. The slot style provides the best balance between zero backlash, torsional stiffness and low bearing load. With two sets of identical slot machines, the mini slit coupling is usually constant velocity by style and handles angular, parallel and axial offset. Available in 6 and 8 mm diameters and allowable speeds up to 70,000 rpm, slit couplings certainly are a reliable one piece coupling design that methods the efficiency of a bellows coupling.
Rotating shaft-driven mechanical pieces are commonly found in all types of machinery that accomplish the various processes and functions of modern industry.
o Shaft misalignment will place stresses on shafts and related elements of the assembly such as 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 utilized to compensate for shaft misalignment, whether the misalignment can be an intentional or an unintentional section of the design.
