As a leading manufacturer specializing in precision transmission components, Henan San Kuang Machinery Technology Co., Ltd. presents our Module 3 Gear Set with 4:1 Ratio and 500 Nm Torque, crafted from high-grade 40Cr alloy steel. This gear set is designed to deliver reliable power transmission in demanding industrial applications, ensuring optimal performance and extended service life. Our factory, spanning 10,000–30,000 square meters, utilizes advanced machining centers and stringent quality control processes to produce gear sets that meet the highest standards of accuracy and durability.
The 4:1 reduction ratio provides a balanced combination of speed reduction and torque multiplication, making it ideal for conveyor systems, hoists, mixers, and other heavy-duty machinery. With a rated torque capacity of 500 Nm, this module 3 gear set can handle moderate to high loads while maintaining smooth operation. The 40Cr material, through proper heat treatment, achieves excellent hardness and wear resistance, reducing the risk of pitting or tooth breakage under cyclic stress.
Key Features & Technical Specifications:
- High Precision Gear Profile: Manufactured to DIN 6-7 grade accuracy, ensuring low noise and vibration during operation.
- Heat Treatment: Carburizing and quenching process provides a hardened case depth of 0.8–1.2 mm, with core hardness of 30–35 HRC for toughness.
- Optimized Tooth Geometry: Profile shift and crowning reduce edge contact stress and improve load distribution.
- Versatile Mounting: Compatible with standard industrial gearbox housings (e.g., K, F, R series) and can be customized for non-standard applications.
- Finish Options: Available with phosphating, black oxide, or zinc plating for corrosion resistance (upon request).

Frequently Asked Questions (FAQ)
-
Q: What is the exact tooth count for this 4:1 ratio gear set?
A: For a module 3 gear set with a 4:1 ratio, typical tooth counts are 20 teeth on the pinion and 80 teeth on the gear. However, custom tooth counts can be designed to meet specific center distances. -
Q: Can this gear set be used in a right-angle gearbox?
A: The gear set is designed for parallel shaft gearboxes. For right-angle applications, we offer bevel gear sets separately. Please consult our sales team for compatibility. -
Q: What is the maximum operating temperature for this gear set?
A: The 40Cr material can operate continuously at temperatures up to 150°C (302°F) without significant loss of hardness. However, we recommend using appropriate lubricants for high-temperature environments. -
Q: Do you provide heat treatment certificates?
A: Yes, we can provide material test reports and hardness test results upon request. Our quality management system ensures traceability for each batch. -
Q: Is the gear set supplied with keyways or splines?
A: Standard sets come with keyways according to DIN 6885. Custom keyway dimensions or spline configurations are available as per your drawing or specification. -
Q: What is the lead time for a sample order?
A: For standard module 3 gear sets, our lead time is typically 15–20 working days. For customized versions, please allow 25–30 working days. We can expedite for urgent orders. -
Q: How do you ensure the gear set's noise level is low?
A: Our gear sets are manufactured with high-precision hobbing and optional grinding, achieving grade 6-7 accuracy. This minimizes transmission error and noise. We also conduct noise testing in our quality lab. -
Q: Can I get a sample before placing a bulk order?
A: Yes, we offer sample orders with a small quantity (1-2 sets). The sample cost is deductible from the bulk order quantity. Please contact us for sample pricing.
