High-power Density Couplings

Voith expanded its TurboBelt TPXL portfolio of fill-controlled couplings to include 500-kW, 800-kW and 1,250-kW versions, which combine hydrodynamics with intelligent control technology to optimize performance. The integrated controller matches the output torque exactly to the startup parameters of the belt conveyor system, thus reducing wear and increasing service life. Due to its high-power density, the TurboBelt TPXL range requires only half the volume of conventional couplings and therefore can be easily integrated into drive trains, the company reported. The 800 and 1250 TPXL offers up to 1,600 and 7,960 Newton meters of torque, respectively. The coupling concept consists of an integrated controller, an integrated oil pump and an oil supply unit. This lays the groundwork for accurate predictive maintenance to effectively keep the total cost of ownership low, the company reported. The line’s hydrodynamic operating principle enables wear-free power transmission without the need for a mechanical connection, Voith reported. In this way, the system’s lifespan is expanded, and maintenance costs are decreased significantly. Rugged construction makes the portfolio ideal for use in demanding environments and tasks, such as open-pit mining applications, the company reported.
