RB, RC Series PIV Chains (positive infinitely variable chains)
These chains are used for the roller type infinite speed variators of the textile industry, on automotive variable speed drives as well as in variable pitch V grooves.
The simple and efficient PIV variator is a good alternative to an electric drive. P. I. V. Roller Chains used on infinitely Variable R-Transmission. In addition to the long service life of the chain, this also achieves very smooth operation of the transmission and favourable material stressing.

Due to the negligible power losses the variator performs with very high efficiency, even when running under partial load. High control precision.
The qualities of the " torque-transformer " admits high torques also with low speeds.
In many cases, our PIV chains products are fit, form and function interchangeable with units made by other manufacturers, such as Rexnord, Link-Belt, AC Compacting etc..
The high protection-type allows to operate in dirty environments without expensive additional features.
Chain links contains packs of hardened steel slats which slide freely from side to side to conform with grooves in the wheel faces.
This unique self forming tooth capability results in positive no slip transmission and long chain life.
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 or variators are used in printing presses, textile machinery, paper converting, and packaging equipment, among other applications.
As opposed to belt or traction drives, all PIV chain driven to be positive with zero slip.

In many cases,
our PIV chains 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.
Their essential qualities are:
Minimal maintenance-expenses and high efficiency enables economic solutions, even at continuous operating.
PIV parts. PIV’s are used in all industry to provide mechanical variable speed power transmission. we acquired the machinery, inventory and intellectual property to manufacture OEM PIV parts.
This acquisition fits into our growth plan and will provide expanded capabilities and products to help better serve our customers.
The PIV infinitely variable gear is a universally recognised device whose carefully studied design, proven operational safety and versatility make it easily adaptable to a wide variety of applications in all branches of both mechanical engineering and manufacturing industry.
All Torque Transmissions supplies and services PIV gear chains.
PIV Gear Design
Essential elements of all PIV gears are two pairs of conical wheels which are movable on their shafts in an axial direction and are connected by a special chain.
An opposite axial movement of the conical wheels will change the pitch circle of the chain and thereby the speed of the output shaft.
The system A gear has conical wheels with radial grooves and a slatted tooth chain.
The laterally movable slats engage the tooth spaces of the conical wheels and transmit the adjusted torque through contact.
The simple and efficient PIV variator is a good alternative to an electric drive.
Slip free power transmission, maximum accuracy of speed setting and good maintenance of the adjusted ratio are features of this design.
The system R gear has been developed, an in many instances higher speed and wider speed ranges as well as lower power ratings are required.
The conical wheels of this type are smooth.
The chain consists of cylindrical rollers, pivotably mounted on their longitudinal axes, and transmits the torque through pressure action.
All moving parts of both types of PIV gear are manufactured from high grade steel and run in an oil bath.
The chain tension is maintained through an automatic re-tensioning device. PIV Gear Servicing compaies are also use our PIV chains.
All moving parts of the gear are automatically lubricated by splash lubrication. The temperature of the gear depends on the load, the circulation of air, and the room temperature.
