Beam Couplings
Ever-power made beam couplings have great angular misalignment capabilities, are zero-backlash and have a balanced style for reduced vibration by boosts to 6,000 RPM. They are produced from a single little bit of aluminum or stainless steel with multiple units of spiral cuts to supply larger stiffness and better all-around misalignment capacities than traditional one beam couplings. Ever-electricity 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 created bellows couplings have substantial torque and torsional stiffness capabilities, are zero-backlash, have a balanced design, and may accommodate all kinds of misalignment. They are comprised of two anodized aluminum hubs and a stainless steel 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 simply flex while leftover rigid under torsional loads. Ever-electricity manufactures bellows couplings hubs with or without keyways in clamp or established screw styles with inches, metric, and inch 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 action 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 ranging 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 guarding 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 produced from acetal. They are made by Schmidt-Kupplung in Germany and are RoHS3 compliant.
Disc Couplings
Ever-power made disc couplings have huge torque and torsional stiffness features, are zero-backlash, possess a balanced design, and can accommodate all forms of misalignment. They will be manufactured in single disc models for compact installations and dual disc styles for larger misalignment capabilities. Ever-electric power 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 collection screw designs with bore sizes ranging from 1/8″ to 1-1/4″ and 3mm to 32mm. They are generally used in powerful stepper servo devices where precise motion control is required.
Jaw Couplings
Ever-power manufactured zero-backlash jaw couplings have a highly customizable three-piece design, have high dampening capabilities, and can accommodate all types of misalignment. The two light weight aluminum hubs press fit onto an elastomeric center spacer known as “the spider” allowing for constant zero-backlash operation. Ever-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 set 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 match 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 made oldham couplings have an extremely customizable three-piece style, are zero-backlash, and also have substantial parallel misalignment capacities. Two anodized aluminium hubs press match the mating slots of the center disk allowing for zero-backlash operation and low bearing loads. Ever-electric power 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 resources allowing the user to complement coupling performance with program requirements. They are commonly used in stepper servo devices that require a higher parallel misalignment coupling.
Slit Couplings
Ever-electricity slit couplings happen to be an alloy, one piece configuration designed to provide smooth transmission of motion, excessive torsional stiffness, low bearing loads, and extended life. The slot routine provides the best equilibrium between zero backlash, torsional stiffness and low bearing load. With two models of identical slots, 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 are a reliable one piece coupling design that methods the efficiency of a bellows coupling.
Rotating shaft-driven mechanical parts are commonly found in all types of machinery that perform the many processes and features of modern industry.
o Shaft misalignment will place stresses on shafts and related parts of the assembly such as for example bearings, which can bring about early failing of both.
o Shaft ends could be misaligned radially or perhaps 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 area of the design.

Ever-powerdrive couplings are power transmission parts used to few the shafts of varied mechanical devices, also to compensate for shaft misalignment, reducing stress upon shafts and bearings. Beam-style couplings are suitable for servo applications, providing 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 designs, sizes, and products 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 presents 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-electric power 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 requirements. At Helical, we’ve considered the guesswork out of picking the precise servo coupling for the application by factoring in essential element dynamics such as for example shaft misalignment, space requirements, torque, and RPM.
