Under the extreme conditions of mining and heavy construction, the transmission clutch endures massive torque shocks and thermal loads. The Friction Plate serves as the core executive element of the clutch. It is not merely a switch for power engagement and disengagement but the key determinant of smooth shifting and transmission efficiency.
Designed specifically for mining drill rigs and heavy construction machinery gearboxes, this product is a composite of high-performance friction materials and a high-strength core steel plate. It offers excellent friction performance, impact resistance, and heat resistance. As a critical spare part for the transmission system, it ensures every clutch action is precise and stable under high-load operations, maintaining the smooth operation of mining machinery.
High-Performance Friction Layer: The surface utilizes sintered bronze or high-heat-resistant resin-based composites. This material offers excellent thermal stability, withstanding the instantaneous high temperatures generated during clutch engagement, preventing a drop in friction coefficient due to heat fade .
Vulcanization Bonding Process: The friction material layer is firmly bonded to the core steel plate via a high-temperature vulcanization process. This is not simple adhesion but an integrated structure formed through chemical cross-linking, ensuring the friction layer never delaminates or warps under severe vibration and thermal cycling.
Groove Design: The plate features precise oil grooves . These not only help control the friction torque but also facilitate the rapid expulsion of lubricating oil during disengagement and quick oil film buildup during engagement, achieving "fast connect, fast disconnect" and reducing wear during half-engagement.
High-Strength Core Steel Plate: The substrate is selected from 65Mn spring steel or 50CrV alloy steel, processed via precision stamping and heat treatment. This imparts high flatness and bending fatigue strength, preventing distortion under high torque transmission.
Unprocessed Gear Teeth: The internal or external gear teeth remain in their natural metallic state without additional surface treatment . This retains the original high hardness and sharp edges of the steel, ensuring a tight, zero-backlash fit with the clutch hub splines for rigid torque transmission, preventing slippage.
Customizable Surface Treatment: Although the teeth are typically untreated, we offer oxidation or spray-paint services for the steel plate surface upon request to enhance rust resistance or differentiate models.
Stable Clutch Control: During drill feeding or heavy equipment starting, this friction plate provides linear and stable engagement force. It eliminates shifting shocks, protecting transmission gears and drive shafts.
Excellent Impact Resistance: On bumpy mining roads, the transmission system faces constant shocks. The tough structural design effectively absorbs some impact energy, reducing mechanical damage to the drivetrain.
Reliable Torque Transmission: With an optimized friction coefficient and precise tooth profile matching, the product offers high torque transmission capacity. Even in extreme conditions like muddy hill climbs, it ensures 100% power output without slippage or loss.
As a Critical Spare Part, this friction plate is widely used in:
Mining Drill Rig Gearboxes: Controlling power flow to the rotary motor and feed system, enduring frequent engagement shocks.
Heavy Construction Machinery: Power shift transmissions in large wheel loaders, bulldozers, and motor graders.
Mining Dump Trucks: Used in clutch packs within hydraulic transmissions, ensuring braking and power distribution during heavy downhill hauling.
Crane Slewing Systems: Controlling the smooth start and stop of the boom rotation.
Friction Coefficient Testing: Every batch undergoes friction and wear testing on a bench rig to ensure dynamic/static friction coefficients meet design requirements.
Flatness & Thickness Inspection: Precision gauges verify single-plate flatness and stack-up height to ensure uniform pressure distribution across multi-plate clutch packs.
Hardness & Metallographic Analysis: Inspecting the hardness and microstructure of the steel plate post-heat treatment to ensure no internal cracks or decarburization.
Cleanliness: Thoroughly clean oil sludge and metal debris from the transmission before installation to prevent scoring the new friction surface.
Run-in Period: After installing new plates, a brief "run-in" procedure is recommended to allow the friction surface to fully mate with the opposing steel plates for optimal performance.
Fluid Matching: It is recommended to use heavy-duty transmission fluid specified by the manufacturer to ensure matching friction coefficients and cooling effects.
