Gear rack, also known as a linear gear or rack and pinion, is a type of gear system used to convert rotary motion into linear motion. It consists of a straight metal or plastic bar with teeth on one side, called the rack. The teeth on the rack mesh with a gear, known as the pinion, which rotates and moves the rack in a straight line.
Gear racks are commonly used in various applications that require precise and controlled linear motion. Some examples include:
CNC machines: Gear racks are used in CNC machines for the precise movement of the cutting head or workpiece along the X or Y-axis.
Industrial automation: Gear racks are utilized in automated systems for material handling, assembly lines, and robotic applications.
Elevators: Gear racks are a key component in elevator systems, providing the necessary linear motion for the elevator car.
Packaging machinery: Gear racks are used in packaging equipment to enable smooth and accurate movement of products or packaging materials.
Printing industry: Gear racks are employed in printing presses to ensure precise and consistent movement of the printing head or paper.
Stage and theater equipment: Gear racks are used in stage and theater applications for moving scenery, curtains, and other stage elements.
Automotive industry: Gear racks are utilized in automotive steering systems to convert the rotational motion of the steering wheel into linear motion for the wheels.
Machine tools: Gear racks are found in various machine tools, such as lathes and milling machines, for precise movement of the cutting tools.
