PRODUCTS DRIVES & CONTROLS Helping to provide the best solution
In the current environment of optimising cost and performance, it is always a challenge to define the best technical solution for all possible industrial applications. This challenge requires a high degree of product innovation to fulfill the maximum requirements of the technical community, as Gates Transmission Power explain
T
he variety of applications e.g. lifting, handling, conveying and
other applications, such as exercise machines, require a comprehensive range of mechanical features. The Gates BLACK FLAT high performance polyurethane flat belt, available with combinations of different types of polyurethane compounds and cords, offer a range of solutions compared to other lifting elements like roller chains and steel ropes. Gates’ polyurethane timing belts are
made of high quality, abrasion resistant material in combination with high strength steel or aramid cord. Polyurethane belts are generally low maintenance, high tensile strengths and are abrasion and UV resistant. They are durable against moisture and detergents, oil and fat, and are chemical resistant. They are resistant to some acids and alkalis and can be produced to meet specific requirements. Standard polyurethane grades are not anti-static. A special anti-static polyurethane grade is available on request. Applications for lifting and pulling
such as elevators, car wash machines, car park equipment, industrial doors

and vehicle body lifting in the automotive industry, requires high performance lifting elements. Polyurethane flat belts with various steel cord constructions offer application specific solutions for tensile strengths and required pulley diameters. Various belt sizes can cover a range of minimum pulley diameters of 38mm up to a maximum tensile strength of 307,5kN (=> table belt tensile strength / pulley diameters). For corrosion critical applications and
applications with direct food contact, it is essential to have belts with a completely encapsulated tensile member with no exposed cord on the edges and no flights. This, together with a special polyurethane grade allows compliance to EU food regulations (N°1935/2004). Belts with steel cords can also be used to transmit data or even electric power through the cords. For this application, the polyurethane body on the belt ends are removed to set the steel cables free. Electric connectors can be applied. The standard temperature range is
from -5°C to 70°C. For use in cold environments, special polyurethane
grades are available down to an environmental temperature of -30°C. The Gates BLACK FLAT belts are characterised by smooth running and low elongation. Open ended belts are typically secured
by conventional clamp fastening plates. For flat belts this is often problematic because the belt may slip out of the clamp due to its slippery surface. To avoid this, Gates has developed a new generation of clamps especially for flat belts. On this new clamping system, called FIX - FLAT, the belt end is equipped with teeth, fixed inside a toothed clamp. That ensures a secure connection and reduces or even avoids the risk of slipping out of the clamp body. This simple but effective fastening system can increase the range of potential applications for flat belts. It is patent pending. The range of Gates’ BLACK FLAT products allows performance optimised and cost efficient solutions for all kinds of applications.
