## Technical guides
- [Forged Gear or Cut Gear? A Total-Cost Comparison for Buyers](https://www.luchigears.com/en/knowledge/forged-gear-vs-cut-gear-total-cost/) — Unit price hides the real difference. A line-by-line comparison of material yield, machining hours, die amortisation and fatigue life, and the batch size where the two routes cross over.
- [GB/T, DIN or AGMA? Reading Gear Accuracy Grades Without Getting Lost](https://www.luchigears.com/en/knowledge/gear-accuracy-grade-gb-din-agma-mapping/) — The same gear can be called grade 6, grade 7 or AGMA 10 depending on the standard. How the three systems map, what each grade actually controls, and what every step up costs.
- [Planetary or Parallel-Shaft? Choosing the Architecture Before the Gear](https://www.luchigears.com/en/knowledge/planetary-vs-parallel-shaft-gearbox/) — Power density, axial length, efficiency and tolerance sensitivity compared — plus the applications where a plain parallel-shaft layout still beats a planetary set on total cost.
- [Sourcing Gears for EV Reducers: Capacity, Tolerances and the 16-Week Reality](https://www.luchigears.com/en/knowledge/nev-reducer-gear-sourcing-capacity/) — Why high-precision EV gears quote at 12–16 weeks, the specification items that actually control noise, and how to book grinding capacity before the shortage does it for you.
- [Gear Steel Selection: 20CrMnTi, 20CrMo, 42CrMo and 40Cr Compared](https://www.luchigears.com/en/knowledge/gear-steel-grade-selection/) — Four grades cover most gear enquiries, but they are not interchangeable. Hardenability, case depth by module, distortion behaviour and the inspection that catches a substitution.
- [Tractor Transmission Gears: Six Failure Modes and the Checklist That Prevents Them](https://www.luchigears.com/en/knowledge/tractor-gear-failure-modes/) — Agricultural duty breaks gears differently from road duty. What pitting, root cracking and spline wear each tell you about the process, and the seven items to put in a purchasing specification.
- [Diagnosing Gear Whine: Mesh Frequency, Sidebands and Ghost Orders](https://www.luchigears.com/en/knowledge/gear-noise-diagnosis-order-analysis/) — A practical route from a noise complaint to the process variable behind it — how to calculate mesh frequency, read sidebands, and tell a design problem from a manufacturing one.
- [Planetary Gear Sets: Ratios, Planet Count and the Assembly Rules That Bite](https://www.luchigears.com/en/knowledge/planetary-gear-set-kinematics-ratio/) — One equation covers every planetary configuration. How to read it, why four planets is not always better than three, and the two assembly conditions that reject a design before it is built.
- [Distortion After Carburising: Why It Costs More Than the Heat Treatment](https://www.luchigears.com/en/knowledge/heat-treatment-distortion-control-gear/) — Ovality, coning and lead change each come from a specific cause. How press quenching, fixture design and a proper grinding allowance budget turn distortion from a scrap source into a controlled variable.
