Q: What is the difference between spur and helical gear?
A: Spur gears have straight teeth and are simpler to manufacture, but they are noisier at higher speeds. Helical gears have angled teeth, providing smoother operation and higher load capacity at the cost of axial force and slightly higher cost.
Q: When to use bevel gears?
A: Bevel gears are used when you need to change the direction of rotation (e.g. 90° power transmission), such as in differential systems or right-angle drives.
Q: How do internal gears differ?
A: Internal gears have teeth on the inner surface. They mesh with external gears, often used in compact gearboxes or planetary systems where space is limited.
Q: What precision tolerances do you support?
A: We manufacture gears with tolerances up to DIN 6 / AGMA 11 (or as per customer spec), controlled via CMM inspection and gear measurement systems.
Q: Which materials and surface treatments are available?
A: We offer carbon steel, alloy steel, stainless steel, nylon, etc. Surface treatments include carburizing, nitriding, black oxide, zinc plating, and polishing.
Q: Can you manufacture based on drawings or samples?
A: Yes, we accept CAD files, 3D models, or physical samples and reverse engineer to produce custom gears.
Q: What is the typical lead time?
A: For prototypes, 2–3 weeks; bulk orders generally take 4–6 weeks, depending on complexity and quantity.
Q: Do you match gear sets or assemblies?
A: Yes, we can provide matched gear sets that are pre-fitted and tested for meshing and noise control.
