Goodyear 390-5M-9 HTD Timing Belt: 5M Profile, 390 mm Pitch Length, 9 mm Width, 78 Teeth, 5 mm Pitch

Goodyear HTD (High Torque Drive) timing belt is a type of synchronous timing belt that is designed to provide efficient power transmission in applications requiring high torque. HTD timing belts are an improvement over the traditional trapezoidal timing belts, offering enhanced load-carrying capabilities, higher efficiency, and improved performance in a wide range of industrial and mechanical systems. Here are some key features and characteristics of HTD timing belts. Tooth Profile: HTD timing belts have a curvilinear tooth profile, which means that the teeth are rounded and provide a larger contact area with the pulley's grooves. This design enhances power transmission efficiency and reduces wear and noise compared to trapezoidal tooth profiles. Pulley Design: The pulleys used with HTD timing belts are designed with matching curvilinear grooves to accommodate the rounded teeth. This design ensures a more positive engagement between the belt and pulley, reducing the risk of slippage. Applications: HTD timing belts are used in a wide range of applications where precise synchronization of motion and high torque transmission are required. These applications include robotics, conveyors, printing machines, packaging equipment, and more. High Torque Transmission: HTD timing belts are designed to handle higher torque loads compared to trapezoidal belts, making them suitable for heavy-duty applications. Reduced Noise and Vibration: The rounded tooth profile reduces noise and vibration during operation, contributing to a smoother and quieter performance. Increased Efficiency: The improved tooth engagement and reduced friction result in higher power transmission efficiency. Better Load Distribution: The curvilinear profile distributes the load more evenly across the belt and pulley, extending the belt's lifespan. When selecting an HTD timing belt for a specific application, it's crucial to consider factors such as torque requirements, speed limitations, available space, and pulley dimensions. Manufacturers provide specifications and guidelines to help users choose the appropriate HTD timing belt for their needs.

• Fiberglass Cord for length stability and very low stretch
• Polychloroprene rubber compound for high adhesion
• Nylon fabric facing for wear resistance and high tooth shear strength
• Improved design for increased power rating over trapezoidal profiles allows for narrower belts
• Less noise generation as compared to comparable trapezoidal timing belts
