Product Name: Industrial Precision Spliced Gear Ring / Spliced Ring
Gear
Core Introduction
Our spliced gear ring is a customized large-diameter transmission
part designed to solve the limitations of integral gear rings, such
as difficult integral casting, inconvenient long-distance
transportation, high installation difficulty and high mold cost.
Adopting professional segmented splicing technology, it realizes
high-precision assembly of split structures, effectively overcoming
the size restrictions of traditional integral gear rings, and is
the preferred core component for large rotary automation equipment,
heavy machinery and precision transmission systems.
All products adopt strict material selection and precision
machining process, with uniform tooth profile, stable zero-backlash
transmission, low operation noise and strong load-bearing capacity.
The splicing interface is precisely calibrated to ensure overall
roundness and assembly accuracy, no jamming during long-term
operation, stable positioning and excellent durability.
Key Product Advantages
✅ Break Size Limitations: Support ultra-large diameter customization, no restriction of
integral forging and casting, perfectly solve the problem that
super-large gear rings cannot be transported and installed
integrally.
✅ High Precision & Zero Backlash: Precision tooth processing and seamless splicing calibration,
multiple tooth surface contact during operation, eliminate
transmission gap, ensure accurate positioning and repeat operation
precision.
✅ Stable & Durable: High-strength alloy steel material, overall heat treatment, high
hardness, wear resistance and impact resistance, effectively reduce
later maintenance cost and extend service life.
✅ Cost-Effective & Flexible: Segmented production reduces production and transportation costs
compared with integral large gear rings; support non-standard
customization of size, modulus and hardness to meet diverse
equipment needs.
✅ Easy Installation & Maintenance: Split structure, lightweight single piece, convenient on-site
assembly, disassembly and replacement, greatly saving construction
and maintenance time.
Application Scenarios
Widely used in semiconductor automation equipment, aerospace
precision machinery, medical pharmaceutical equipment, new energy
lithium battery production lines, heavy engineering machinery,
rotary processing equipment, intelligent logistics transmission and
other high-precision and heavy-load industrial fields.

Process procedure:
Forging process flow quality control:
- Raw material steel ingot into warehouse(test the chemical content)
- Cutting→ Heating(Furnace temperture test)
- Heat treatment after forging(Furnace temperture test) Discharge the
furnace(blank inspection)
