The latest addition is the internationally patented VTP®-Pulley, a V-belt pulley in a completely new design incorporating all aspects of optimized performance of V-belt pulleys. One of the improvements most worthy to mention is a combination of design and quality castings, which has resulted in a weight reduction of up to 50 % compared to conventional V-belt pulleys. Furthermore, due to the tilted spokes, the internal tensions of the V-belt pulley are reduced considerably.
Higher effects transmission
The V-belt pulleys will have a lower working temperature – up to 17°C lower than with standard V-belt pulleys. This is a great importance for the lifetime of the V-belt pulley. ACC®–surface treatment is a new and more efficient surface treatment of castings and naturally all of our VTP®–pulleys and the other V–belt pulleys are treated in this plant. Among other advantages the ACC®–process adds a high chemical resistance to oil, petrol, brake fluid and lubricants and exceptional physical properties of the cured film (6H-pencil hardness) and priming paint and finishing paint can be applied direct to the ACC®-surface. This is a very environmentally friendly process, being free from any air pollutants.
The iron quality GGG60 allows the circumferential speed to be increased up to 100 m/s and the resistance to wear of the V–belt pulley against the belt is improved.
