SERVO COUPLINGS
Servo couplings from Ever-power can be found in a wide variety of styles, sizes, and supplies to match differing software requirements. Choosing the correct servo coupling can be a difficult procedure that involves many performance factors including: shaft misalignment, RPM, space requirements, torque, and others. Matching a shaft coupling with these elements is critical to system functionality. Ever-power presents servo couplings in rigid, beam, bellows, curved jaw, disc, and oldham types permitting the user to choose the coupling that best fits their request. All Ever-power couplings will be zero-backlash and manufactured in our Marlborough, MA factory.
Servo couplings are offered in many different attachment styles as well as a vast array of sizes and products to suite your specific application and/or customized requirements. Maintaining optimum program performance relies on effectively complementing a shaft coupling based on your specific performance and app requirements and expectations. At Helical, we’ve taken the guesswork out of selecting the complete servo coupling for the application by factoring in crucial part dynamics such as shaft misalignment, space requirements, torque, and RPM. Have a look at our coupling goods.

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

Beam Couplings
Ever-power manufactured beam couplings have excessive angular misalignment capabilities, are zero-backlash and have a balanced style for reduced vibration in boosts to 6,000 RPM. They are produced from a single little bit of aluminum or stainless with multiple sets of spiral cuts to supply higher stiffness and better all-around misalignment capacities than traditional solo beam couplings. Ever-power beam couplings can be found 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 light duty power tranny applications where precise movement control is desired.
Bellows Couplings
Ever-power created bellows couplings have huge torque and torsional stiffness functions, are zero-backlash, possess a balanced design, and can accommodate all forms of misalignment. They are made up of two anodized metal hubs and a stainless bellows making a light in weight 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-electric power manufactures bellows couplings hubs with or without keyways in clamp or placed screw styles with inches, metric, and inches to metric bores which range from 1/8″ to 1 1″ and 3mm to 25mm. They are commonly used in high performance stepper servo systems where precise action control is required.
Controlflex Couplings
Ever-power Controlflex couplings certainly are a three-piece assembly with a balanced design and style made up of two hubs joined to one or two centre inserts called frogs. This style creates a compact low inertia versatile coupling capable of speeds up to 25,000 RPM. Clamp design hubs are manufactured with in ., metric, keyed, and keyless bores which range from 1/8” to 1-1/2” and 3mm to 40mm for large customizability. The unique design and style of the frog concentrates forces onto its flexible limbs enabling low bearing loads protecting sensitive little bearings in applications such as for example encoders or tachometers. Controlflex couplings happen to be also electrically isolating since the hubs do not feel and frogs are made from acetal. They happen to be manufactured by Schmidt-Kupplung in Germany and are RoHS3 compliant.
Disc Couplings
Ever-power manufactured disc couplings have substantial torque and torsional stiffness functions, are zero-backlash, possess a balanced design, and can accommodate all forms of misalignment. They are created in single disc variations for compact installations and double disc styles for bigger misalignment capabilities. Ever-power disc couplings are comprised of two anodized light weight aluminum hubs, stainless steel disc springs, and a centre spacer (double disc simply) creating a compact low inertia coupling with the capacity of boosts to 10,000 RPM. Hubs are made with or without keyways in clamp and placed screw types with bore sizes ranging from 1/8″ to 1-1/4″ and 3mm to 32mm. They are generally used in powerful stepper servo systems where precise action control is required.
Jaw Couplings
Ever-power created zero-backlash jaw couplings possess a highly customizable three-piece style, have high dampening features, and may accommodate all forms of misalignment. The two lightweight aluminum hubs press fit onto an elastomeric centre spacer named “the spider” allowing for constant zero-backlash operation. Ever-vitality zero-backlash jaw couplings possess a balanced design and style for lowered vibration at speeds up to 8,000 RPM. Hubs are produced with or without keyways in clamp or collection screw types with bore sizes ranging 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 found in applications with huge acceleration/deceleration curves where dampening and specific motion control are required.
Oldham Couplings
Ever-power manufactured oldham couplings have an extremely customizable three-piece design, are zero-backlash, and have excessive parallel misalignment features. Two anodized lightweight aluminum hubs press fit into the mating slots of the center disk allowing for zero-backlash procedure and low bearing loads. Ever-power oldham couplings possess a balanced design for decreased vibration at speeds up to 4,500 RPM. Hubs are produced 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 purchased in three components allowing the user to match coupling performance with system requirements. They are commonly used in stepper servo devices that require a higher parallel misalignment coupling.
Slit Couplings
Ever-vitality slit couplings will be an alloy, one piece configuration made to provide smooth transmission of motion, large torsional stiffness, low bearing loads, and long life. The slot pattern provides the best equilibrium between zero backlash, torsional stiffness and low bearing load. With two sets 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 speeds up to 70,000 rpm, slit couplings are a reliable one piece coupling design that methods the efficiency of a bellows coupling.
Rotating shaft-driven mechanical parts are commonly used in all forms of machinery that accomplish 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 failure of both.
o Shaft ends could be misaligned radially or angularly, exhibit axial displacement, or experience a blend of all three.
o Drive couplings can be used to compensate for shaft misalignment, whether the misalignment is an intentional or perhaps an unintentional section of the design.
