Description
Custom epicyclic gear set engineering for a central sun gear, multiple planet gears, an internal ring gear and carrier matched as one working system.
Construction and engineering scope
A planetary gear set requires compatible tooth geometry and center distance across the sun, planets and internal ring. Load sharing also depends on carrier and pin stiffness, bearing support, tooth quality and assembly alignment.

Technical parameters
| Core elements | sun gear, planet gears, internal ring gear, planet carrier |
|---|---|
| Gear form | spur or helical, by drawing |
| Module / DP | by drawing or measured sample |
| Pressure angle | commonly 20°; other values by drawing |
| Material options | 20CrMnTi / 18CrNiMo7-6 / 42CrMo or equivalent, subject to review |
| Heat treatment | carburizing + hardening, nitriding or through hardening as specified |
| Inspection | tooth geometry, runout, hardness and dimensions per RFQ |
Typical configurable options are shown for RFQ planning only. Final values are fixed by the approved drawing, material specification, heat treatment, ratio, duty and inspection plan.
Applications and selection
Confirm tooth counts as a matched set, required ratio, continuous and peak torque, speed, duty cycle, backlash target and available envelope. For reverse engineering, send the complete mating set whenever possible.
Customization options
Engineering review can cover tooth count and ratio, spur or helical geometry, material and heat treatment, motor or shaft interface, output flange or spline, bearing arrangement, lubrication, sealing, backlash class and inspection documentation. Features are confirmed against the approved drawing rather than assumed from a similar model.
Installation and maintenance
Check shaft alignment, pilot fit, fastener grade and tightening method before commissioning. Do not exceed the confirmed continuous or peak torque, radial load, axial load or input speed. For replacement work, verify the mounting drawing and output interface before ordering.
Quality and inspection
Inspection planning can include material traceability, hardness, tooth geometry, runout, dimensional inspection and assembly checks according to the RFQ and approved quality plan. Ask for the required inspection level before quotation.
FAQ
Can you manufacture from a drawing or sample?
Yes, the engineering review can start from a drawing, sample, tooth data or a complete gearbox identification. Final feasibility is confirmed after dimensional and material review.
What information is needed for a replacement?
Send model or nameplate, quantity, ratio, motor or input speed, output torque or duty, shaft/flange dimensions, mounting drawing and clear photos. For individual gears, add tooth count, module or DP, pressure angle, face width and material/heat-treatment requirements if known.
