As a leading manufacturer with over a decade of expertise in heavy machinery components, Henan San Kuang Machinery Technology Co., Ltd. is proud to present our high-precision DIN 6 Grade Spur and Helical Gears, engineered specifically for the demanding environments of crusher and conveyor systems. Built in our expansive 10,000-30,000 square meter facility, these gears are the result of rigorous processes and a commitment to quality, ensuring they deliver unmatched durability, efficiency, and reliability for your critical industrial operations. We understand that downtime is costly, which is why our gears are designed to withstand extreme loads and harsh conditions, providing a robust solution that enhances the performance and longevity of your equipment. Trust in our proven experience, backed by a comprehensive quality management system, to supply the power transmission components your business depends on.
Our DIN 6 Grade gears represent the pinnacle of precision engineering for heavy-duty applications. The DIN 6 accuracy classification signifies exceptionally tight tolerances in tooth profile, lead, and pitch, resulting in smoother meshing, reduced vibration, and lower noise levels during operation. This precision directly translates to higher efficiency, less energy consumption, and significantly extended service life for both the gear itself and the entire drive train. We utilize high-grade alloy steels, such as 20CrMnTi or 42CrMo, which are subjected to advanced heat treatment processes like carburizing and quenching. This ensures a hardened, wear-resistant tooth surface (typically HRC 58-62) while maintaining a tough, shock-absorbing core, making them ideal for handling the impact loads and variable torques common in crushing and material handling.
Key Technical Specifications and Advantages:
- Superior Load Capacity: The helical gear design offers gradual tooth engagement, distributing load over a greater contact area compared to spur gears. This leads to higher torque transmission capacity and smoother, quieter operation, which is crucial for large conveyor systems and crushers.
- Enhanced Durability: The combination of premium material selection, precise manufacturing to DIN 6 standards, and controlled heat treatment creates a gear with exceptional resistance to pitting, bending fatigue, and abrasive wear.
- Custom-Engineered Solutions: We understand that off-the-shelf parts rarely fit perfectly. Our engineering team can customize gears based on your specific requirements, including module, number of teeth, bore diameter, keyway specifications, and overall dimensions.
- Optimized for Harsh Environments: These gears are built to perform reliably in environments with dust, moisture, and temperature variations commonly found in mining, quarrying, and aggregate processing plants.

Frequently Asked Questions (FAQ):
-
Q: What does "DIN 6" grade mean for these gears?
A: DIN 6 refers to a precision grade per the DIN 3962 standard. It indicates very high manufacturing accuracy concerning tooth profile, pitch, and lead. Gears of this grade mesh with minimal backlash and vibration, leading to efficient, quiet, and long-lasting operation in demanding applications. -
Q: Can you provide gears for my existing crusher model from a different manufacturer?
A: Absolutely. We specialize in providing replacement and custom gears. Please share the technical drawings, part numbers, or samples of your existing gear. Our engineering team can reverse-engineer and manufacture a compatible or improved DIN 6 grade replacement. -
Q: What is the main advantage of choosing a helical gear over a spur gear for my conveyor?
A: Helical gears engage more gradually than spur gears. This results in smoother and quieter operation, higher load-carrying capacity, and the ability to transmit motion between non-parallel shafts. They are often preferred for high-speed, high-torque conveyor drives. -
Q: What materials do you typically use, and what heat treatment is applied?
A: We primarily use high-strength alloy steels like 42CrMo and 20CrMnTi. These are subjected to carburizing or induction hardening followed by quenching and tempering. This process creates a hard, wear-resistant tooth surface while maintaining a tough, ductile core to withstand impact loads. -
Q: Do you offer different surface finishes?
A: Yes. Depending on the application's speed and noise requirements, we can provide gears with ground teeth for the highest precision and finish, or hobbed/shaped teeth which are a cost-effective solution for many heavy-duty applications. -
Q: What is your typical lead time for a custom gear order?
A: Lead time varies based on gear size, complexity, and order quantity. For standard sizes, it can be 4-6 weeks. For large, fully custom gears, it may take 8-12 weeks. We provide a firm timeline upon reviewing your specifications. -
Q: How do I determine the correct specifications to order?
A> You will need key parameters such as: Module (or DP), Number of Teeth, Pressure Angle, Face Width, Bore Diameter, and Keyway尺寸. Our technical sales team can guide you through this process if you provide your equipment model or existing gear details. -
Q: What quality assurance measures do you have in place?
A> Our production follows a stringent quality management system. We conduct in-process inspections and final checks using gear measuring instruments to verify dimensions, tooth profile, and hardness against the DIN 6 standard and your specifications.
