Products Description
A segment large module gear rack is a rack that is divided into segments, each segment having a different tooth profile. The purpose of the segmented gear rack is to allow for smooth and accurate motion in situations where the gear rack needs to change direction or speed.
Segmented gear racks are commonly used in machinery that requires high precision and accuracy, such as CNC machines, industrial robots, and automation systems. The different tooth profiles on each segment of the gear rack allow for smoother transitions between gears and more precise control over the linear motion of the machine. Usually the segmented rack is divided into arc and straight gear rack.
materials of segmented gear rack
Material type |
Specific grades/specifications |
Key performance features |
Applicable working conditions |
|
High quality carbon structural steel |
45# steel (modulation treatment) |
Low cost, medium strength after quenching and tempering (220-250HB), easy to process |
Light to medium loads, no strong impact, and low life requirements (such as light lifting equipment and manual adjustment mechanisms) |
|
Alloy structural steel |
40Cr (quenching and tempering + surface quenching) |
After quenching and tempering, ob≥980MPa, surface quenching (HRC50-55) improves wear resistance and toughness is better than carbon steel |
Medium load - heavy load, slight impact scene (such as small and medium-sized rolling mills, heavy conveying equipment, mining machinery transmission) |
|
High strength alloy steel |
20CrMnTi (carburizing and quenching) |
Carburized layer depth 0.8-1.2mm, surface HRC58-62, good core toughness (≥900MPa) |
Heavy load, strong impact, high wear resistance requirements (such as large excavator travel mechanism, metallurgical equipment roller drive) |
|
Wear-resistant alloy cast steel |
ZG35CrMnSi (overall quenching) |
High overall strength (ob≥780MPa), wear resistance, high temperature oxidation resistance, can be cast into complex shapes |
Extremely heavy loads, high temperature/dust environments (such as steel plant continuous casting machine straightening machines, large forging equipment racks) |
|
Stainless steel |
304/316L (surface hardening treatment) |
Acid and alkali corrosion resistance, surface hardening to improve wear resistance (HRC45-50) |
Food processing, chemical industry, marine and other corrosive environments (such as corrosion-resistant conveyor lines, offshore platform lifting mechanisms) |
main functions of gear rack
Transferring Motion: The primary function of a gear rack is to transfer rotational motion into linear motion or vice versa.
Positioning and Precision: Gear racks are crucial for achieving accurate positioning and precise linear motion.
Load Distribution: Gear racks help distribute the load evenly along their length.
Force Amplification: By utilizing a gear rack with a gear, mechanical systems can achieve force amplification.
Backlash Reduction: Gear racks can help reduce or eliminate backlash in a gear system.
Versatility and Adaptability: Gear racks offer versatility in mechanical system design. They can be combined with various types of gears, such as spur gears, helical gears, or bevel gears, to create different motion transmission configurations.
