Understanding Gear Racks in Modern Industry
What Is a Gear Rack?
A gear rack is a toothed bar that interacts with a pinion gear to facilitate linear motion. As the pinion gear rotates, it moves the rack in a straight line, enabling applications like CNC machines, steering mechanisms, and industrial automation. This rack gear configuration provides an efficient method of converting between rotary and linear motion.
Gear racks are linear mechanical components essential in converting rotary motion into linear motion or vice versa. By combining with a pinion gear in various types of gears, they provide precision, durability, and versatility in industrial and mechanical applications. Selecting the right gear rack for your process ensures optimal performance in automation, machinery, and engineering systems.
Specifications and Dimensions
Gear Racks in Metric Sizes
Gear racks are available in various metric sizes to meet specific requirements. Common sizes include module 0.5, module 1, module 1.5, module 2, module 3, module 4, module 5, and larger modules like module 10 and module 20 for heavy-duty applications.
The module is a standardized unit that defines the size of the gear teeth. Metric sizing ensures compatibility with international standards (ISO and DIN) and a broad range of industrial machinery, including CNC systems, automation equipment, and heavy-load applications.
Size Applications
Module 0.5 to Module 2: Suitable for lightweight applications like precision machinery and robotics. Module 3 to Module 5: Commonly used in industrial automation and medium-load systems. Module 10 and above: Ideal for heavy-duty equipment handling high loads and stress.
