Features and benefits HT500 drives – the TCO drive solution: Energy efficient – maintenance free HT500 high torque synchronous drive system is the latest generation in the Dodge® synchronous product line. The HT500 belt is manufactured with polyurethane, carbon fiber cords and a black nylon tooth facing, featuring the modified curvilinear tooth profile. This drive system utilizes Dodge’s Taper-Lock® bushing system to deliver our most power dense synchronous drive in a compact package. Also available from stock: Fin fan sprockets with QD* bushings, and minimum-plain-bore (MPB) sprockets....

Features and benefits_ DOaoGE* The US Department of Energy encourages the use of synchronous belts in all motor installations to maintain an overall efficiency rating of 98% across a wide load range. The HT500 synchronous belt is designed to offer the energy efficiency of a synchronous belt drive in a compact design. HT500 75 Hp drive Example Energy savings = Annual energy use x (1 - n1/n2) Mechanical drive comparison Additional benefits from HT500 • No maintenance cost • Zero slip • Constant time, speed • Positive engagement • Less downtime HT500 SYNCHRONOUS DRIVE SYSTEM CATALOG

The Institute Electrical and Electronics Engineers (IEEE) conducted a survey to identify major causes of motor failures; the chart below is an abstract from their Petro-Chemical paper PCIC-94-01. It concludes that 51% of all motor failure is attributed to bearing problems. By decreasing the belt pull and overall overhung load, a motor bearing will last longer. Bearings Shaft couplings ■ Rotor bar ■ Stator winding ■ External - environment, voltage and load. Likely to happen again. ■ Unknown - no root failure analysis HT500 75 Hp synchronous drive vs. V-belt drive comparison General...

Design load Equation 1 Design load = (Motor load) x Service factor x (% Reducer efficiency/100) Motor load: From user/OEM Service factor: From Table 1 % Efficiency: From reducer manufacturer Actual operating loads known In such cases where the actual operating load is known, design the belt drive for the actual operating load rather than for a load based upon the motor name plate. Use Equation 1 to calculate the proper drive design load based upon motor load (name plate or measured) when the belt drive will be installed on the reducer output shaft. Select a driven load category whose...

Selection of a stock HT500 belt drive system involves these eight steps: 1. Calculate the design horsepower 2. Select the belt pitch 3. Select the sprockets and belt length 4 Select the proper belt width 5. Check and specify stock drive components 7. Calculate belt tensioning requirements 8. Verify speed reducer overhung load Sample drive selection problem A blank Low-speed drive design information sheet can be found on page 25. This form provides a convenient method for collecting data to properly design or convert to a HT500 belt drive. In this example, an ore conveyor is powered by an...
