Specon Power Transmission

Fairchild, under its SPECON product line, manufactures PIV chain drive transmissions, differential drive transmissions, planetary gearboxes and we can repair or provide replacement units for SPECON®, CUBIC® or other Fairchild products, and often times for other manufacturers’ products, such as those made by Rexnord® or Link-Belt®.

RATIO AND SPEED CONTROL

Vari-Chain® PIV Chain Transmissions are adjustable variable speed transmissions and variators featuring a metal PIV chain that positively engages grooves in conical wheels, providing a drive that does not slip. Seven sizes ranging from fractional to fifteen horsepower and speed ranges of 2:1 to 6:1 are available in various configurations and arrangements. These PIV chain drive transmissions are used in printing presses, textile machinery, paper converting, and packaging equipment, among other applications. In many cases, SPECON PIV transmissions or PIV chains products are fit, form and function interchangeable with units made by other manufacturers, such as Rexnord®, Link-Belt®, AC Compacting® or other manufacturers. Please contact the factory for interchange information concerning Link-Belt® units.

SPEED AND POSITION REGISTER/CONTROL

Differential Draw Transmission (MDD) with Integral Phase Shifting Differential transmissions accomplish Primary Speed Control and Secondary Position Control. When the Speed Control screw of the unit is set to any position within its range the ratio between the input and output shafts are fixed or preset. The Secondary Position Control is accomplished by rotating the correction shaft which accesses the correction differential. This can accomplish an incremental correction which offsets the phase angle or controls position between the input and output shafts. These PIV chain drive transmissions are often used in pump drives, extractor drives, machine tool drives, screw conveyors, and winder drives, among other applications. In many cases, SPECON PIV transmissions or PIV chains products are fit, form and function interchangeable with units made by other manufacturers, such as Rexnord®, Link-Belt®, AC Compacting® or other manufacturers. Please contact the factory for interchange information concerning Link-Belt® PIV transmission units.

POSITION OR REGISTER CONTROL

Cubic® Differential Planetary Transmissions offer the same advantage as the Phase Shifting Differential Planetary Transmissions but in a more compact housing. The CUBIC® is available in six sizes each for the following: 1:1 (FHT), 3:1 (FT) and Right Angle Units (FRA). The Right Angle units have five ratio options. CUBIC® Differential Transmissions are available with torque capacities of 500 to 10000 #-in. for the Right Angle and the 1:1 ratio units and 167 to 3300 #-in. for the 3:1 ratio unit. These Cubic® planetary gearboxes are often used in conveyor drives, printing presses, paper and web machinery, plastic film machinery and packaging applications.

REPAIR AND UPGRADE SERVICES

Backed by over 50 years experience, our services include repair, rework and replacement of PIV Chain, gears, shafts or other internal components, or the upgrade of entire transmission or gearbox assemblies now in the field. In fact, our customers are delighted when their Specon® and Cubic® products in service for several decades may be economically repaired to like new working condition at our North Carolina facility. Although we specialize in Specon® PIV chain transmissions and Cubic® Planetary gear drives, we have the capability and expertise to repair virtually any mechanical variable speed drive; including the major domestically produced mechanical PIV variable speed chain drives such as Rexnord®, Link-Belt®, P.I.V.®, AC Compacting® or other manufacturers. Please contact the factory for interchange or repair information concerning Link-Belt® PIV transmissions or other manufacturers’ units. Fairchild maintains an extensive inventory of OEM original housings, gears, PIV replacement chains, wheel faces, bearings, seals, couplings, clutches, shafts and other parts to provide parts to you quickly at a competitive price.
