Torsion Control Products (TCP) has developed a line of spring couplings specifically for modern diesel engines as used, for example, in construction machines and agricultural vehicles. These products attenuate torsional vibration, isolate resonance, protect against overload and shock, reduce noise, improve the service life of bearings and gears and increase system durability.

Spring couplings have long been an integral component of powertrains. With their unique torsional characteristics, the Torsion Control Products (TCP) spring couplings are optimized for modern diesel engines that produce lower emissions and more power in smaller packages at lower operating speeds. They are typically used in construction machines, agricultural vehicles, mining equipment, marine powertrains and industrial equipment. The comprehensive range of TCP spring couplings is used in gearboxes, hydrostatic pump drives, power shifts and hybrid transmissions. Since 2017, TCP, founded more than 30 years ago, is part of Timken. Its integration in the Timken Mechanical Power Transmission Group has strengthened the global sales capability of the US company.
Spring couplings work in both lubricated and non-lubricated environments
The all-steel construction of the spring couplings is space-efficient and ensures a long service life, while their performance remains consistent throughout the products’ lifespan. Ambient temperature has virtually no impact on the performance or durability of the couplings. They can be used in both lubricated and non-lubricated environments and continue to operate and attenuate drivetrain vibration in even the roughest applications.
With their Smart Damping system, the TCP spring couplings can be tuned to supply damping only when needed and pure isolation when damping is detrimental. This reduces torsional spikes at start up, shut down and transient events, improving durability and coupling life.
Couplings to be tailored to customer specifications
The TCP range of spring couplings covers a torque range from 27 to 27,000 Nm. Their multistage stiffness capability allows optimized system tuning and they have numerous installation and mounting options. Their integral shaft support capability eliminates the need for additional bearing support. The couplings can also be tailored to customer specifications and special requirements. Whether it is in construction, agricultural, mining, industrial or marine equipment, the product by TCP can address the needs of users’ applications.
