When to Use Helical Gears?

Choosing between helical and spur gears often comes down to balancing smooth operation against manufacturing complexity and cost. The wrong gear choice can impact both performance and project budgets, especially when axial thrust forces require additional bearing or housing modifications. Use helical gears when you need reduced noise (10-15 dB quieter than spur gears), higher […]

When to use spur gears?

brass and steel spur gear

Selecting the right gear type can make or break your mechanical design — especially when balancing performance, cost, and manufacturability constraints. With decades of experience machining precision gears for robotics, automation, and industrial equipment, even seasoned engineers sometimes overlook how spur gear advantages align with specific application requirements. Spur gears are the optimal choice for […]

How can gear undercut be prevented in design?

Gear undercut causes more design rejections than any other gear manufacturing issue we see. From medical device gears to precision robotics components, preventing undercut early saves costly redesigns and ensures reliable performance. Gear undercut is prevented by using profile shift coefficients, increasing pressure angle from 20° to 25°, or maintaining minimum tooth counts (17+ teeth […]

When does gear undercut happen?

Gear undercut isn’t just a design calculation—it’s a manufacturing reality that can compromise tooth strength and create costly failures in precision assemblies. When designing gears for tight-tolerance applications like aerospace actuators or medical device housings, understanding undercut thresholds becomes critical to both performance and cost control. Gear undercut happens during the manufacturing process when the […]

How to Calculate Spur Gear Center Distance ?

Designing gear systems requires getting center distance calculations right from the start. Incorrect center distance leads to premature wear, noise, and system failure. With experience machining custom gears for demanding applications, proper center distance specification dramatically improves both performance and manufacturability. Standard center distance equals half the sum of pitch diameters: C = (D₁ + […]
