Introduction
In robotics, timing belts and pulleys are integral for motion control, providing precise and reliable power transmission. They have many different applications which include:
Actuation Systems: Timing belts and pulleys are used to transfer motion from motors to various parts of the robot, ensuring precise control of movements.
Conveyor Systems: They drive conveyor belts, enabling the smooth and synchronized transport of components or game pieces from one mechanism to another.
Rotational Mechanisms: Employed in robotic arms and joints, as well as turn tables for turrets and shooters, they ensure synchronized and accurate rotational movements.
Linear Motion Systems: Used in linear actuators, timing belts provide controlled linear motion. Linear slides like the goBilda Viper slide is an example of these applications.
Timing Belts
Timing Belts
Timing belts are a type of toothed belt that ensures synchronous movement between the belt and pulleys. Often times, they are made from durable materials such as rubber, polyurethane, or neoprene and have embedded fibers or metal reinforcements to provide strength and stability, but with low torque applications they can be 3D printed out of materials such as TPU.
Key Features:
Toothed Design: The teeth on the belt match with the grooves on the pulley, preventing slippage and ensuring precise movement.
Material Composition: Often reinforced with materials like fiberglass or Kevlar to enhance strength and durability. Low torque applications, as is often the case in FTC, TPU 3D printed belts can me made and will function quite well.
Low Stretch: Timing belts, as compaired to chaines have very little strech. This minimal elongation ensures consistent performance and accuracy.
Pulleys
Pulleys
Pulleys are wheel-like components with grooves around their circumference that match the teeth on timing belts. They come in various sizes and configurations, depending on the application requirements.
Key Features:
Grooved Surface: Matches the teeth on the timing belt to ensure a secure and precise fit.
Material Options: Commonly made from materials like aluminum, steel, or plastic, chosen based on the application’s load and environmental conditions.
Diameter Variations: Available in different diameters to achieve desired gear ratios and mechanical advantages.
