Description
Central sun gears for new planetary stages, replacement assemblies and custom epicyclic mechanisms.
Construction and engineering scope
The sun gear meshes simultaneously with multiple planet gears, so tooth geometry, concentricity, shaft interface and heat treatment have direct influence on load sharing and noise.

Technical parameters
| Tooth count | by drawing / matched gear set |
|---|---|
| Module / DP | by drawing |
| Pressure angle | by drawing; 20° is common |
| Bore / spline | plain, keyed, splined or integral shaft by drawing |
| Material options | case-hardening or alloy steels by duty |
| Surface condition | ground, shaved or finished as specified |
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
For a replacement sun gear, send the mating planet and ring data as well as bore/spline dimensions. Tooth count alone is not enough to ensure compatibility.
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.
