Overview

Starter Ring Gear Capabilities

AmTech International delivers precision-manufactured starter ring gears for OEMs worldwide, supporting a wide range of engine and industrial applications. Our advanced production process ensures every ring gear meets exacting standards for strength, durability, and dimensional accuracy.

Raw Material Preparation

High-quality steel is rolled from straight bar stock into coils. These coils are then cut along the centerline to create individual ring blanks, which are welded to form complete rings—initially oversized to allow for precise machining.

Precision Machining

Ring gear blanks undergo a two-step machining process. First, the inner diameter is machined to meet exact drawing specifications. Next, the outer face and diameter are precisely finished to required tolerances.

Tooth Hobbing

Each ring gear’s teeth are formed using dedicated hobbing tools, custom-made and maintained for every unique part number. This ensures consistent tooth profile and optimal gear mesh for every production run.

Teeth Chamfering

Chamfering is performed to create a smooth, angled edge on the gear teeth, facilitating easy engagement with the mating pinion and reducing friction during operation.

Deburring

Following machining, hobbing, and chamfering, any residual burrs or sharp edges are removed using a two-step deburring process involving a deburring wheel and nylon brush, ensuring a safe and smooth finish.

Cleaning

All machined parts are thoroughly cleaned using high-pressure systems and anti-corrosion oil to remove chips, dust, and contaminants, preparing them for heat treatment.

Induction Hardening

The teeth undergo induction hardening to significantly increase surface strength and wear resistance, extending the operational life of the gear.

Final Cleaning & Tempering

A final cleaning removes any remaining residues before tempering. Tempering relieves internal stresses, enhancing the toughness and ductility of the finished gear.

Final Product

AmTech manufactures over 275 types of starter ring gears for OEM customers globally, with sizes ranging from 8″ to 36″ in diameter. Every gear is produced to meet stringent quality standards for reliable engine starting and long-term performance.
