- Product Description
Inner Ring Gear - High-Precision Planetary Gear Solutions
Henan Yizhi Machinery's Inner Ring Gear conveys enterprise-level accuracy for heavy-duty transmission frameworks. With 15 a long time of fabricating ability and ISO certification, our arrangements highlight progressed metallurgy capabilities traversing 12 fabric grades counting 20CrMnTi and SAE4340. Engineered to ISO 6 Grade accuracy with surface hardness coming to 58-62 HRC, our inside ring gears accomplish predominant stack dispersion through specialized carburizing and acceptance solidifying forms. Custom module ranges from 0.5-50 with adaptable helix points guarantee ideal execution in planetary reducers, winches, and machine instrument applications.
What is an Inner Ring Gear?
The item speaks to a specialized component where equip teeth are absolutely cut on the inner circumference of a round and hollow ring. Not at all like outside gears, this arrangement permits numerous planet gears to lock in at the same time with the inside teeth.
This interesting plan understands basic mechanical challenges in present day industry. You get critical torque duplication inside compact spaces where conventional parallel-shaft gearboxes would be as well bulky. The stack dissemination over numerous engagement focuses decreases stretch concentrations and expands operational life.
The concave tooth profile makes prevalent contact characteristics compared to outside adapt networks. This comes about in lower contact stretch and improved weariness resistance for your heavy-duty applications.

Key Features and Advantages
Superior Material Engineering
Our inner ring gears utilize premium low-carbon amalgam steels with specialized warm treatment forms. The carburizing treatment makes a solidified surface layer whereas keeping up a bendable center for affect absorption.
Compact Design Excellence
The inner work setup gives uncommon control thickness. You accomplish higher torque transmission in littler bundles compared to ordinary outside adapt systems.
Enhanced Load Distribution
Multiple planet equip engagement focuses convey loads equitably over the Inner Ring Gear teeth. This decreases person tooth stretch and avoids untimely wear in requesting applications.
Flexible Customization Options
We suit assorted prerequisites through:
- Custom tooth checks and module specifications
- Variable helix points from 5° to 45°
- Multiple fabric grades for diverse environments
- Surface hardness optimization based on your application needs
Low Minimum Order Quantities
Single-item generation capabilities guarantee you get precisely what you require without pointless stock investment.
Industrial Applications
