A Gear Rack is a linear gear used in conjunction with a pinion to convert rotational motion into linear motion. This mechanical component is essential in various industries, including automotive, aerospace, manufacturing, and robotics, due to its efficiency, precision, and durability. Gear racks are designed to handle high loads and provide smooth, accurate movement, making them ideal for applications like CNC machines, conveyor systems, and steering mechanisms.
Our gear racks are engineered to meet industry standards, with detailed parameters to help you select the right product. Below is a comprehensive table outlining key specifications.
| Parameter | Description | Standard Values |
|---|---|---|
| Module (M) | Size of the gear teeth, affecting load capacity and engagement. | 1, 1.5, 2, 2.5, 3, 4, 5, 6 |
| Pressure Angle | Angle between the tooth face and the gear wheel tangent. | 20° (standard), 14.5° (optional) |
| Material | Composition of the gear rack for strength and durability. | Carbon Steel, Stainless Steel, Alloy Steel |
| Hardness | Surface hardness measured after heat treatment. | 45-55 HRC (Hardness Rockwell C) |
| Length | Total linear length of the gear rack. | 500mm to 3000mm (custom lengths available) |
| Width and Height | Cross-sectional dimensions for mounting and stability. | Varies by module (e.g., M2: 20mm x 20mm) |
| Load Capacity | Maximum load the gear rack can handle without deformation. | Up to 5000 N per linear meter (dependent on module and material) |
| Accuracy Grade | Precision level based on manufacturing standards. | DIN 5 to DIN 10 (higher number indicates lower precision) |
Gear racks are versatile components used in numerous applications. Here are some common uses:
What factors should I consider when selecting a gear rack?
Consider the module size, material, hardness, length, and application environment. The module must match the pinion gear, and the material should suit load and corrosion requirements.
How do I maintain a gear rack for longevity?
Regular lubrication with appropriate grease reduces wear and noise. Inspect for debris, misalignment, and tooth damage periodically. Avoid overloading beyond specified capacity.
Can gear racks be customized for specific needs?
Yes, we offer customization in length, material, module, and mounting options. Provide your application details for tailored solutions.
What is the difference between a gear rack and a lead screw?
A gear rack converts rotational motion to linear motion via a pinion, offering high load capacity and speed. A lead screw uses a threaded shaft and nut, providing higher precision but lower load capacity.
How do I install a gear rack properly?
Ensure a flat, aligned mounting surface. Use appropriate fasteners and torque specifications. Check engagement with the pinion for smooth operation without binding.
What are the signs of gear rack wear or failure?
Common signs include increased noise, vibration, uneven movement, and visible tooth damage. Regular maintenance helps prevent premature failure.
Are there environment-specific gear rack options?
Yes, stainless steel or coated gear racks are available for corrosive or high-moisture environments. Select based on exposure conditions.
How does module size affect performance?
Larger modules handle higher loads but may require more space. Smaller modules offer finer precision and smoother operation for lighter loads.
Can I use a gear rack in high-speed applications?
Yes, but ensure proper lubrication, alignment, and material selection to minimize heat and wear. Consult specifications for speed limits.
What standards do your gear racks comply with?
Our products meet international standards such as DIN, ISO, and AGMA for quality, accuracy, and safety.
