A Round Gear Rack is a linear gear with a curved or circular profile, designed to mesh with a pinion gear to convert rotational motion into precise linear movement. Unlike traditional straight racks, the round variant offers unique advantages in applications requiring smooth, continuous motion in a circular path, making it ideal for rotary tables, indexing mechanisms, turntables, and robotics. Its construction ensures high durability, low noise, and efficient power transmission, catering to industries such as automation, aerospace, manufacturing, and medical equipment.
Our Round Gear Racks are engineered to meet stringent industrial standards, with parameters that define their performance and compatibility. Below is a detailed breakdown of the specifications.
| Parameter | Range | Standard Values |
|---|---|---|
| Module (Pitch) | 1 to 10 mm | Common: 2 mm, 3 mm, 5 mm |
| Number of Teeth | 20 to 200 teeth | Customizable based on diameter |
| Outer Diameter | 50 mm to 2000 mm | Standard sizes: 100 mm, 300 mm, 500 mm |
| Width/Thickness | 10 mm to 100 mm | Typical: 20 mm, 30 mm, 50 mm |
| Accuracy Grade | DIN 5 to DIN 10 | High precision: DIN 5 for minimal backlash |
| Pressure Angle | 20° or 14.5° | Standard: 20° for better torque transmission |
Round Gear Racks are versatile components used in various industries for precise motion control. Common applications include:
Q: What is the difference between a round gear rack and a straight gear rack?
A: A round gear rack has a curved or circular profile, allowing for motion in a circular path, whereas a straight gear rack is linear and used for straight-line motion. The round version is ideal for applications like rotary tables and turntables, offering smoother operation in confined spaces.
Q: How do I select the right module for my round gear rack?
A: The module (pitch) depends on the application's torque requirements and space constraints. Smaller modules (e.g., 1-2 mm) are for light-duty, high-precision tasks, while larger modules (e.g., 5-10 mm) handle heavier loads. Consult our technical team for specific recommendations based on your pinion gear and operational conditions.
Q: Can round gear racks be customized for non-standard diameters?
A: Yes, we offer custom manufacturing for diameters outside the standard range. Provide your requirements, including diameter, number of teeth, and material, and we can produce racks tailored to your application, ensuring compatibility and performance.
Q: What maintenance is required for a round gear rack?
A: Regular lubrication with high-quality gear oil is essential to reduce wear and prevent corrosion. Inspect for debris and wear periodically, especially in high-load environments. For plastic racks, avoid exposure to extreme temperatures and chemicals to prolong lifespan.
Q: Are round gear racks compatible with all pinion gears?
A: They are designed to mesh with standard pinion gears of matching module and pressure angle (typically 20°). Ensure the pinion gear's material and hardness are compatible to avoid premature wear. Custom pinions can be sourced if needed for specialized applications.
Q: What industries commonly use round gear racks?
A: These racks are widely used in automation, aerospace, manufacturing, robotics, medical devices, and entertainment systems (e.g., rotating stages). Their ability to provide precise circular motion makes them suitable for any application requiring reliable rotational movement.
Q: How do I install a round gear rack properly?
A: Installation involves aligning the rack with the pinion gear ensuring minimal backlash, securing it with appropriate fasteners (e.g., bolts or clamps), and verifying smooth operation through a test run. Use alignment tools for accuracy, and refer to the manufacturer's guidelines for torque specifications and mounting procedures.
Q: What is the typical lead time for ordering custom round gear racks?
A: Lead times vary based on complexity and quantity; standard orders ship within 2-4 weeks, while custom designs may take 4-8 weeks. Contact our sales team for an exact timeline based on your specifications.
