High-Strength Industrial Grinding Gear Rings for Heavy-Duty Transmission and Construction Machinery

Gear Ring Description

In heavy-duty applications, a gear ring is a high-strength annular gear component specifically engineered

to withstand substantial loads. Typically featuring thick-walled construction and high-strength materials,

it is extensively employed in heavy-duty transmission systems.

Key Features

Key features include substantial ring wall thickness and high material strength (predominantly alloy steel),

with tooth surfaces undergoing strengthening treatments such as carburising and quenching.

Advantages include robust load-bearing capacity, excellent impact resistance, wear resistance, and durability.

They withstand prolonged heavy loads and high-frequency impacts, delivering extended service life.

Working Principle

Manufactured from high-strength alloy steels like 20CrNiMo or 42CrMo, enhanced through forging

and tempering processes to boost overall strength. Gear surfaces achieve 58-62 HRC hardness post-carburising

and quenching. During operation, they mesh with high-torque pinions to stably transmit torque under heavy-duty conditions.

The thick-walled structure effectively distributes stress across the tooth surface, preventing root fractures or excessive tooth wear.

Applications

Commonly employed in heavy-duty equipment, including excavator slewing rings in construction machinery,

luffing gear rings in cranes, transmission rings in mining crushers, and reduction gear rings in marine propulsion systems.
