The Gates GT®3 timing belt is a 2 mm pitch, 3 mm wide, single-sided neoprene belt with fiberglass reinforcement, designed for synchronous power transmission. It has a breaking strength of 93 N per 1 mm of belt width and a working tension of 734 N for a 25.4 mm width. Operating temperature ranges from -30°C to +100°C. The belt features improved load capacity, reduced noise, and better registration compared to GT®2 belts, to which it is an equivalent replacement. The part number A36R51M391030 corresponds to a 391-tooth belt, though this exact configuration is not listed; the series includes 391-tooth belts with pitch lengths of 782 mm, 30.787 inches, and similar dimensions for adjacent tooth counts.
For power transmission applications, a belt and pulley drive system are one of the most common and cost-effective methods used to transfer motion in a drive system. synchronous timing belts, with their defined pattern and evenly spaced teeth, mate with matching timing belt pulleys and idlers to drive motion in precision equipment. When synchronization between shafts is not a priority, V- belts are an excellent alternative. V-belts ride in the groove of compatible V-belt pulleys and idlers. Flat belts find considerable usage in applications requiring small pulley diameters, high belt surface speeds, low noise levels, low weight, and inertia. Round belts or O-Rings are used with grooved pulleys. A cable drive system is another means of transmitting synchronous motion. Consisting of an extremely flexible cable and uniquely grooved pulleys, the Synchromesh Drive system offers design possibilities previously not achievable. Timing belt and cable accessories, belt tensioners and tension testers assist in the maintenance and operation of a belt drive system.
