Straight Bore Keyway Hexagonal Square Threaded Spline


Intermediate Connecting ShaftThe center connector member may be fixed or have limited axial freedom, either spring-loaded (as in quick-change joints) or free. The center connector must be specified to suitindividual needs. In spring-loaded applications, ends may be hex, square, spline,Woodruff key or specialized design requirements.

A quick-change feature is available on our custom double universal joint, which allows the universal joint to be quickly removed and replaced without tools. This is an importantfeature when machine downtime is crucial. The quick-change universal joint consists oftwo back-to-back single universal joints connected with a spring loaded intermediateshaft. Pinning of outer yokes is not required because the spring tension on theintermediate shaft holds the quick-change universal joint secure at each end.

Couplings

Belden couplings are designed

to satisfy your most difficult

engineering challenges. Belden

offers couplings that are

custom finished to meet all your

special requirements.

Belden couplings allow for motion

control, absorb shock, and

handle a variety of misalignment

and operating conditions. We offer

coupling solutions for all power

transmitting or motion control

functions.

Belden Incorporated: Coupling DivisionSlit Flex Style: b series

The B series of couplings has a cut pattern consisting of two sets of two cuts. Each set ofcuts has two beams that overlap each other, much like a thread that has multiple starts.These beams are slightly shorter in rotational length than those of the C series. This givesthe coupling higher torsional stiffness (lower windup) for greater accuracy. In general,these beams are thicker than those in a C series coupling of an equal outside diameter,this gives the coupling greater torque capacity. Due to the thicker beams and the shorterlength these couplings sacrifice some flexibility to obtain the greater performance.

• Zero backlash

• Two sets of two cuts

• Bore tolerance: +.001”/-.000”

• Accommodates angular and parallel misalignment and axial motion

• Available in aluminum or stainless

Belden Incorporated: Coupling DivisionSlit Flex Style: c series

The C series of couplings has a cut pattern consisting of two sets of one cut. These beamsare longer in rotation and generally not as wide as the B series. These couplings are lighterduty than the B series, and have more windup. The advantage of these couplings is theirgreat flexibility, which results in very low bearing loads. Low bearing loads are essential forthe delicate instruments these couplings are designed to be used with.

Belden Incorporated: Coupling DivisionOldham Couplings

A robust, three part coupler rated for intermittent operation, the Belden Oldham couplinghas zero backlash, high torsional stiffness and offers easy connection of drivers in blind ordifficult installations. The Oldham coupling is widely used for motion control, typically inpositioning tables, fluid delivery systems, and similar applications.

A key feature of the Oldham concept is the exceptional, flex-free, radial misalignmentcapability it provides. As there are no restoring forces, bearing loads are low. Its operationshould not be confused with the jaw coupler which works on different principles.

• Tolerant of pronounced radial misalignment

• Electrically isolating

• Flex-free mechanical action-low bearing loads

• Non-magnetic

• Low inertia

Belden Incorporated: Coupling DivisionSoft Flex Coupling:

Soft Flex Couplings are three piece couplings consisting of two zinc alloy hubs and a softplastic multi-tooth sleeve. With each of the two hubs mounted with set screws onto to thedriver shaft and the other to the driven shaft, the soft plastic transmits torque across thehubs through sheer connection. The sheer connection compensates for angular andparallel shaft misalignment providing protection from vibration and shock loads, andprovides electrical insulation. These couplings are easy to install and maintenance free.

• Good torque shock absorption

• Electrical insulation and good axial freedom

• Excellent resistance to oil and abrasion

• Hubs: zinc alloy

• Sleeve: polyurethane or hytrel

• Mounting: set screw

Universal Joint A mechanical device that can transmit torque and/or rotary motion from one shaft toanother at fixed or varying angles of intersection of the shaft’s axis.

Pin and Block Universal Joint Also know as the Cardan or Hooke joint, the pin and block is the simplest unitavailable. It allows for a more positive transmission of rotating power or torque thanconventional flexible couplings.

Cross and Bearing Universal Joint A forged cross with a needle bearing connection provides minimal backlash andprecise positioning without compromising torque capacity.

Needle Bearing Universal Joint Needle bearings are installed at the pin ends to reduce backlash and increaseprecision and RPM capability.

Torque Torque is the force that causes rotation. Operating torque is the amount of torquethat is transmitted during normal operation. Torque is commonly expressed in pound-inches (lb-in), pound-feet (lb-ft), or Newton-meters (Nm).

• Multiply pound-inch (lb-in) x .112985 for Newton-meters (Nm).• Multiply pound-feet (lb-ft) x 1.35582 for Newton-meters (Nm).• Torque can be calculated using the following formula:• Torque (lb-in) = Horsepower (h.p.) x 63024

rpm

Axial Misalignment Axial misalignment is the amount of axial movement (end play) between the shafts,which is typically caused by motor vibration. Axial misalignment is measured in length units.

Parallel Offset Parallel offset is the parallel distance between shafts, and is measured in length units.

Torsional Stiffness Torsional stiffness is the degree of resistance against twist. It is commonly expressedin pound-inch/radian (lbin/rad) or Newton-meter/radian (Nm/rad).

• Multiply pound-inch/radian (lbin/rad) x 6.47357 for Newton-meter/radian (Nm/rad).

• Multiply pound-inch/degree (lbin/deg) x .01745 for pound-inch/radian (lbin/rad).

Angular Misalignment Angular misalignment is the angle at which the shafts intersect. It is commonlyexpressed in degrees.

Zero Backlash Zero Zero backlash refers to the amount of side to side play within a coupling assembly.

Duty Cycle The load on a universal joint is either intermittent or continuous. Under mostoperating conditions, a joint’s intermittent load capacity is greater than it’s continuousload capacity.
