As a leading manufacturer established in 2014, Henan San Kuang Machinery Technology Co., Ltd. specializes in providing robust and reliable power transmission solutions for heavy industries. Our factory-direct split girth gear with integrated gear hobbing processing service represents a significant advancement in large gear manufacturing. This product is engineered to deliver exceptional performance, durability, and value, directly from our 10,000-30,000 square meter production facility in Luoyang, China. We eliminate intermediaries to offer you superior quality at competitive prices, backed by our extensive experience in serving global markets across North America, Southeast Asia, Europe, and beyond.
Our split girth gear is a critical component designed for large-scale rotating machinery where monolithic gears are impractical due to size, transportation, or installation constraints. The split design allows for easier handling, transportation, and on-site assembly around existing equipment shafts. Combined with our in-house gear hobbing service, we ensure precise tooth profile generation, optimal meshing, and long service life.
Key Product Features & Technical Advantages:
- Factory Direct Sourcing: Purchasing directly from our manufacturing base ensures cost-effectiveness, better quality control, and direct communication with our engineering team.
- Integrated Gear Hobbing Service: We don't just supply gears; we provide the complete processing. Our advanced gear hobbing machines create accurate tooth profiles with tight tolerances, essential for smooth power transmission and reduced vibration.
- Split Construction Design: The gear is manufactured in two or more segments, bolted together to form a complete ring. This design solves logistical challenges and simplifies maintenance.
- Customizable Specifications: Gears are tailored to your specific requirements, including module, number of teeth, face width, bore diameter, and material grade.
- Superior Material Selection: We use high-strength alloy steels or cast steels, chosen for their excellent wear resistance, toughness, and ability to withstand heavy shock loads.
- Precision Machining & Quality Control: Every manufacturing step, from rough machining to final hobbing and inspection, is conducted under stringent protocols to guarantee dimensional accuracy and operational reliability.

- Optimized Performance: Accurate tooth geometry ensures efficient power transfer, minimizes energy loss, and reduces noise and vibration levels.
- Logistical Flexibility: Shipping and handling large-diameter gears become manageable and cost-efficient with the split design.
- Total Solution Provider: From design consultation and material selection to machining, hobbing, and after-sales support, we are your single point of contact.
Frequently Asked Questions (FAQ):
-
Q: What are the main advantages of a split girth gear over a solid one?
A: The primary advantages are related to installation and maintenance. Split gears can be assembled around an existing shaft without removing other components, drastically reducing downtime. They are also easier and less expensive to transport due to their smaller, more manageable segments. -
Q: Can you manufacture gears to match my existing pinion or gear set?
A: Absolutely. We require your existing gear's specifications (module, pressure angle, number of teeth) or even the old gear itself for reverse engineering to ensure perfect meshing and compatibility. -
Q: What is the lead time for a custom split girth gear order?
A: Lead time depends on the gear's size, complexity, and material availability. Typically, it ranges from 8 to 16 weeks. We provide a detailed schedule upon order confirmation. -
Q: Do you provide installation guidance or technical support?
A: Yes, we supply detailed installation manuals, bolt tightening sequences, and alignment procedures. Our technical team is available for remote consultation to support your installation team. -
Q: What quality control measures are in place during manufacturing?
A: Our process includes material certification, in-process dimensional checks, final gear inspection (tooth profile, lead, pitch), and run-out testing. We can provide inspection reports as part of the delivery. -
Q: How do you ensure the alignment and strength of the bolted joint in a split gear?
A: The joint faces are precision-machined to be perfectly flat and perpendicular. We use high-strength fitted bolts and provide specific torque values to ensure the joint acts as a single, rigid unit under load. -
Q: What industries typically use your split girth gears?
A: Our gears are widely used in mining (ball mills, rotary kilns), cement production, chemical processing, power generation, and metallurgy—any industry that operates large rotating equipment. -
Q: Can you provide surface hardening or protective coatings?
A: Yes, we offer various options such as induction hardening, carburizing, or nitriding for tooth surfaces. Protective coatings like paint or epoxy can also be applied to non-working surfaces to prevent corrosion.
With an annual export value ranging between US$2.5 Million and US$5 Million, Henan San Kuang Machinery has established a strong reputation for reliability and quality in international markets.
