- Product Description
Crusher Gear – Heavy-Duty Transmission Solutions for Mining & Aggregate Processing
Product Details
When you're running crushing equipment in demanding environments, you need components that won't let you down. Our Crusher Gear is engineered specifically to handle the extreme loads, continuous vibration, and impact forces common in mining and aggregate processing. As a critical component in your crusher's transmission system, this gear converts motor rotation into the high torque required for efficient material reduction. Each product we manufacture undergoes precision machining and advanced heat treatment to deliver consistent performance in jaw crushers, cone crushers, and impact crushers worldwide.
We fabricate these gears utilizing fundamentally forging or casting processes, depending on your application prerequisites. This approach ensures superior material integrity compared to fabricated alternatives. Our production capability covers diameter across from 500mm to 3000mm, with module ranges from M10 to M30+, appropriate for both standard and custom crusher configurations.
Material selection plays a critical role in gear longevity. We utilize high-grade alloy steels including 45#, 55#, 40Cr, 42CrMo, and 34CrNiMo6. Each material is selected based on your operating conditions—whether you’re processing abrasive rock or softer limestone.

Features and Benefits
Advanced Heat Treatment Process
Our two-stage heat treatment delivers both high hardness and wear resistance. First, the gear blank undergoes deep quenching and tempering to achieve a uniform rough throughout the core. This provides the toughness required to withstand impact loads without fracturing.
Precision Machining Capability
We utilize CNC equip hobbing machines and adapt shapers to accomplish precise tooth geometry. Appropriate involute profile and lead exactness reduce noise, vibration, and untimely wear. This machining accuracy guarantees compatibility when you're replacing gears in existing equipment.
Custom Designing Support
Every crushing application is diverse. Our designing group can adjust tooth thickness, pressure angle, and face width based on your transmission necessities. We also design gears for particular crusher types—whether you require spiral gears for cone crushers or spur gears for jaw crusher drive systems.
Material Traceability
Every batch of steel is tested and fully documented. We keep complete records that trace each finished product back to its original material certification. This full traceability is especially important for industries that need strict proof of material quality.
Applications
Crushing operations demand reliable power transmission. Our gears are already proven in these applications:
Mining and Quarrying: Our high-strength alloy gears are built for extreme conditions in cone crushers, reliably processing hard materials like copper ore, gold ore, granite, and limestone.
Aggregate Production: In sand and gravel operations, jaw crushers, cone crushers, impact crushers, and VSI crushers rely on our gears for continuous, stable performance under varying load conditions.
Cement Manufacturing: Single-stage hammer crushers used for primary limestone crushing require gears that withstand high shock loads. Our carburized gears excel in this demanding application.
Metallurgical Slag Processing: Specialized crushers handling blast furnace slag and steel slag face extreme abrasion. Our surface-hardened Crusher Gear components extend service life in these harsh environments.
Testing & Certification
We maintain ISO 9001:2015 certification for our quality management system. All products comply with RoHS directives for restricted substances.
Each gear undergoes:
· Ultrasonic testing (UT) for internal soundness
· Magnetic particle testing (MT) for surface defects
· Full dimensional inspection using coordinate measuring machines
· Surface hardness verification across the tooth profile
· Core hardness sampling to verify heat treatment effectiveness
Test reports are provided with each shipment upon request.
Installation Guide
Proper installation is critical for optimal gear life. Follow these guidelines:
1. Pre-Installation Inspection: Verify Shaft alignment and bearing condition before installing the new gear. Check keyway dimensions and fit.
2. Cleaning: Remove all protective coatings and contaminants from mating surfaces. Ensure gear teeth are free of debris.
3. Alignment: Use dial indicators to verify concentricity and face runout within specified tolerances for your crusher model.
4. Mounting: Follow manufacturer torque specifications for retaining bolts or mounting hardware. Apply appropriate thread-locking compound where specified.
5. Lubrication: Apply recommended lubricant to all tooth surfaces before initial startup. Verify lubrication system function.
6. Break-In: Operate at reduced load for the first 8-10 hours to allow proper surface conditioning of tooth flanks.

Partners
Your trust, we cherish in heart all times and will reciprocate that trust with unwavering quality.

Packaging & shipping
Your goods are unique, and their journey should be flawless. Therefore, we offer professional and customized packaging services. Our experienced team will evaluate your goods' characteristics, transportation route, and environmental requirements to recommend the most secure solution, such as: wooden crate packaging, sturdy frame packaging, or composite reinforced packaging (wooden crate + iron frame).



Maintenance and Care
Extend your gear service life with these practices:
Regular Inspection: Monitor tooth wear patterns monthly. Uneven wear indicates misalignment or lubrication issues requiring correction.
Lubrication Management: Maintain grease viscosity and cleanliness per crusher manufacturer specifications. Change oil at recommended intervals or when contamination is detected.
Load Monitoring: Avoid prolonged operation above rated crusher capacity, which accelerates tooth fatigue.
Storage: If storing spare gears, apply corrosion-preventive coating and store in dry conditions away from ground contact.
FAQ
Q: Can you manufacture gears for obsolete crusher models?
A: Yes. Provide us with the worn gear or detailed measurements, and we can reverse-engineer a replacement even without original drawings.
Q: What lead time should I expect for custom gears?
A: Standard sizes ship within 4-6 weeks. Custom designs typically require 8-12 weeks depending on complexity and current production schedule.
Q: Do you provide material certificates?
A: Yes. We supply material test reports and heat treatment documentation with each order.
Q: How do I select between induction hardening and carburizing?
A: Induction hardening suits moderate-duty applications with good cost-effectiveness. Carburizing provides superior fatigue resistance for heavy-duty continuous operation. Our engineers can recommend the optimal process based on your operating conditions.
Q: Can you supply matching pinions or complete gear sets?
A: Absolutely. We manufacture both gears and pinions, ensuring proper tooth contact patterns and load distribution.
