PRODUCT OVERVIEW

Internal Gears & Ring Gears for your transmission layout

An internal gear has teeth on the inside of a ring. In a planetary arrangement, it meshes with external planet gears and helps create a compact reduction stage. A ring may also carry a mounting flange, bolt circle, outside locating surface or other housing interface.

Our range includes agricultural wheel-end rings, planetary reducer rings and related transmission parts. The relationship between internal teeth and outside mounting features is important for correct alignment in the assembly.

Part types and features

  • Flanged ring gears
    Internal teeth with mounting faces and a defined bolt pattern.
  • Thin-ring components
    Compact tooth rings where clamping and distortion deserve attention.
  • Wheel-end rings
    Ring components for enclosed reduction arrangements.

MANUFACTURING & INSPECTION

Manufacturing and inspection for this part

Internal cutting requires a suitable tool-access and workholding plan. The YK8132 power skiving machine in the manufacturing base is relevant to discussing applicable internal gear work. Ring stiffness, tool clearance and heat-treatment movement are reviewed before the machining and finishing sequence is agreed.

02

Ring geometry

Roundness, mounting-face relationship and critical wall dimensions.

03

Assembly compatibility

Mating tooth data and any defined backlash or meshing checks.

PRODUCT QUESTIONS

Before you send the drawing

Do you need the planet gear drawing?

Where tooth compatibility or assembly backlash is part of the requirement, send the mating planet data and the assembly reference.

Why do flange and outside dimensions matter?

The ring is located by those interfaces in the housing. Their relationship to the tooth system affects alignment and meshing.

Are ring gears available as standard stocked sizes?

These are custom-manufactured parts. Send your dimensions, material and quantity so we can quote the required part and delivery requirements.
