Couplings & Gears

Product Details:

PAGUFLEX® PLUS shaft couplings... the sure, uncomplicated, economical solution, if angled, radial and/or axially displaced drive shafts are to be frictionally connected.

Double loop-shaped, thermoplastic compensating coupling element made from HYTREL ®, a Thermoplastic Ether Ester Elastomer (TEEE) from DuPont.

Owing to the high reverse bending strength of the flexible material and the cardan-like shaping of the power transmitter, this development is the ingenious, technical solution for shaft displacement problems in motive power engineering, and in measurement and control techniques.

Recommendations for our products are for the design of: shaft-angle encoders, counting mechanisms, tachogenerators, servo valves, elevating tables, feeding drives, pumps, compressors and ventilators, kitchen equipment, office systems, textile machines and for numerous applications in the automobile and aircraft industries.

The one-piece coupling is frictionless, wear less, and silent, and works without any troubling effects (i.e., without troubling structure-borne sounds).

Thus, in changes of direction or rotation, or during torque fluctuations with load direction reversal, PAGUFLEX ® PLUS enables play-free and shock-free power transmission, together with effective vibration damping and sound insulation.

In numerous technical applications, the material HYTREL ® has been successfully substituted not only for established thermoplastics, but also for elastomers. It combines ideally the advantages of both materials, and is therefore the best innovation for flexible shaft couplings.

It enables the opening up of new areas of applications for extremely low and high temperatures. Also, in association with media in which, owing to their sensitivity, elastic elements have shown themselves to be of `limited use´. Further applications are those in which up to now the reverse bending strength of the material has set, narrow limits with regard to mechanical fatigue loading. In these, PAGUFLEX ® PLUS is now the solution.

The high flexibility of the thermoplastic coupling element effectively lightens the burden on the shaft bearings of motors and machines, even in circumstances of large radial and angular alignment errors. With the help of PAGUFLEX ® PLUS, the bearings run quieter, warm-up less, and achieve longer durability, thus lengthening service life.

Product Details:

The double loop coupling uses a moulded plastic element permanently swaged to steel or stainless steel hubs to give a compact design. It forms an effective two-stage coupling with exceptional flexibility in all three modes. Ideal for transmitting rotation in small drives, this type of coupling works without any friction, wear or noise, although its low torsional stiffness makes it less suitable for high precision positioning applications.

 

Exceptional flexibility in all three directions: radial, angular and axial.

Founded in 1975, Stafford Manufacturing Corp. is built on commitment to quality products, superior customer service and employee development. Arthur Stafford started the company on a shoestring budget but with a clear vision of what was required to accomplish those goals.

Stafford Manufacturing Corp. is a manufacturer and distributor of shaft collars, rigid shaft couplings and specialty mechanical components.

They’re used in a wide range of industrial and consumer OEM and MRO applications, including:

Power transmission

Linear motion

Motion control

Fixturing

Material handling

Display

Automation

Assembly

Shaft collars are machine components featuring a simple design that consists of a round metal or plastic ring with a clamp screw or screws. Tightening the screws causes the ring to tighten or loosen around the shaft. When securely tightened, shaft collars can serve as mechanical stops or hold components in place along a shaft. Despite their simple design, shaft collars play an important role in a wide range of industrial applications. 

TYPES OF SHAFT COLLARS

Shaft collars provide three primary functions: 1) holding components in place, 2) locating or positioning components on a shaft, and 3) creating an attachment between shaft and another component. Some of the types commonly available include:

Threaded shaft collars. Threaded shaft collars have a threaded interior that allows for use on threaded shafts, making them an excellent choice for heavy-load applications requiring high axial holding power. The threaded design also allows for easy adjustments and precise positioning.

One-piece shaft collars. They feature a simple design featuring a single screw. They work by surrounding the shaft with an evenly distributed compressive force . Since they cannot be disassembled, one-piece collars are only suitable for applications where the end of the shaft is accessible.

Two-piece shaft collars. These can be completely disassembled, allowing them to be used in situations where the end of the shaft is not accessible. Two-piece collars also provide greater holding force and shock-load resistance.

Hinge shaft collars. Their design allows for easy disassembly and reassembly along the shaft. They consist of a single unit that can be installed without the risk of dropping loose parts.

Heavy-duty shaft collars. Compared to other shaft collar designs, heavy-duty shaft collars feature larger clamping screws and greater outer diameters and widths. The torsional holding capacity of heavy-duty collars is approximately twice that of standard collars.

Shaft Collar Bore Varieties. Bore shaft collars are manufactured in round, threaded, hexagonal, and square configurations. Round bore shaft collars are used as stops, locators, spacers, and bearing faces for a broad range of motion control, power transmission, and mounting applications. They are suitable for use on shafts, piping and tubing, and split hubs. Threaded bore shaft collars provide exceptional axial holding power without damaging threaded shafts. Their simple yet flexible design enables quick assembly and easy adjustments. Hexagonal shaft collars and square shaft collars are exclusively manufactured by Stafford Manufacturing to fit hexagonal or square shafts.

Product Details:

It all began in 1949, when Minnesota inventor Sterling Stageberg designed a unique mechanical variable speed transmission drive. Stageberg's design varied the output speed from a constant input from zero to maximum. Initially, it was used on automotive windshield wipers and became an instant success. The product filled an important industry need at the time, which helped launch the company. It also provided the idea for the Zero-Max brand, a name carried on all of today's Zero-Max products sold throughout the world.

Flexible Shaft Couplings

Shaft misalignment can limit the performance of machines, cause excessive wear, and often lead to premature failure. Flexible shaft couplings can help prevent these issues by transmitting torque while also accommodating for parallel, axial, and angular misalignment between drive components. High performance flexible shaft couplings can also reduce vibration, dampen noise, and protect drive shaft components from overload.

• Proprietary hub machining process leaves a smoother surface for interaction between hub and disk resulting in significantly longer life.
• Balanced design reduces vibration and allows for higher RPM.
• Accommodates a high amount of parallel misalignment (up to 10% of the outer diameter) with very light bearing loads.
• Three-piece design allows for ease of customization, installation, and blind assembly.
• Disks are available in nylon for dampening of impulse loads and noise reduction, acetal for high torque capacity and zero-backlash, and PEEK for high temperature and low outgassing.
• Stops transmission of power during overload conditions.
• Manufactured and stocked at our Marlborough, Massachusetts factory. Special designs are available.
• All Ruland oldham couplings are RoHS3 and REACH compliant.

The Kop-Flex® products continue to innovate the industry with leading solutions such as the evolutionary High-Performance Disc 2.0 coupling, torque monitoring systems, and patented ground bearing technology. The strength of the brand lies in its ability to provide a wide range of critical applications; from high-speed, High-Performance couplings for the Oil and Gas Industry, to high torque gear spindles for Metals and Mining applications.KOP-FLEX introduced the FAST’S® Gear Coupling in 1918. These have allowed KOP-FLEX to maintain its technological leadership in the coupling industry. It has distinguished itself in engineered couplings for high speed or high-performance applications, as well as in mill couplings.

KD® Disc Couplings KD flexible shaft couplings provide reliable transmission of mechanical power. This can be applied where a low maintenance, non-lubricated coupling is required. KD Disc Couplings are specifically designed to accommodate general purpose drive system applications such as centrifugal pumps, compressors, generators, cooling towers, machine tools, printing and pulp and paper machines.KD Couplings transmit torque and provide for both angular and axial misalignment between shafts with a coupling comprised of shaft mounted hubs connected through flexible disc packs with spacer or sleeve assemblies. All KD Couplings use stainless steel discs as flexible members, providing high strength and good corrosion resistance.

Gear CouplingsKop-Flex® offers the widest range of gear couplings, with no limit in sizes. Available with multiple different seal features and lubrication capacities. Available with alloy and nitride gearing to increase strength and extend wear.

FAST'S® Gear Couplings
The FAST’S® design, with its lifetime all-metal end ring, provides up to 300% greater lubricant capacity. This means that longer periods between relubrication may be scheduled. It is the only coupling designed to use oil lubrication. The all-metal end ring, used exclusively in FAST’S® couplings, eliminates the need for any type of perishable lube seal (o-rings, lip seals, cork gaskets, etc.). The end ring not only provides the dam over which lubricant must flow to escape, but it additionally pilots the sleeve with respect to the hub during start-up and shut-down operations. It further eliminates partial tooth disengagement with resulting tooth overloads by providing sleeve teeth which are flush against the inside wall of the end ring. WALDRON® Gear CouplingsFULL ENGAGEMENT TEETHThe WALDRON® gear coupling has been designed with full length tooth engagement with the inherent result of longer life and improved performance. OPTIONAL PILOT RINGSThe standard WALDRON® coupling consists of two identical half couplings. Optional precision steel pilot rings are available when more accurate centering of the two sleeves is required. HIGH MISALIGNMENT SEALCompetitive gear couplings incorporate an O-ring seal. In order to conform with today’s high misalignment capacities, this O-ring must fit into a groove that is larger than the ring. WALDRON® couplings use a truly high misalignment seal that seals remarkably under misaligned conditions.WALDRON® POWERLIGNThis flangeless design transmits identical torques as the standard WALDRON® Coupling. Having a smaller outside diameter, however, it is more compact, lighter, and can run at greater speeds
Elastomeric Couplings Kop-Flex® Elastomeric couplings use a flexible element to compensate for high angular misalignment and dampen torsional vibrations. Many models also feature a no lubrication schedule and provide virtually maintenance-free operation.

As a coupling manufacturer, NBK succeeded in the field of precision miniature shaft couplings.  Beginning with technology development for single-piece construction slit-type couplings, we successfully followed to develop all-stainless steel couplings. At that time, NBK couplings were well matched to the control motors and our marketshare was rapidly increased.  We continued to develop jaw-type, bellows-type, disk-type and more to meet our customers' needs and developing peripheral devices such as servo motors, stepper motors, and encoders we focused on high frequency response, hunting prevention, improving gain, shortening stabilization time, zero backlash.  As a result, NBK developed XG Series, high-gain rubber type couplings based on cutting edge control theory which has been introduced as a new generation type coupling in motion control industry.
