Product Advantages
The GⅡCLZD series disc brake gear shaft adopts an integrated design. Core components include involute cylindrical gears, high-precision gear shafts, brake discs, bearings, and seals. Gears are made of high-quality alloy steel (such as 42CrMo), carburized and quenched, with gear surface hardness reaching HRC58-62, ensuring smooth transmission, wear resistance, and durability; the disc brake part achieves braking through hydraulic or spring-loaded friction pads, with adjustable braking torque and response time ≤0.2 seconds. The product undergoes dynamic balance correction and sealing protection, suitable for harsh environments such as dust and humidity, easy maintenance, and long service life.
1. Integrated Design: Combines transmission and braking functions, reducing space and connecting parts;
2. High-Precision Transmission: Gear accuracy reaches Grade 6 of GB10095, transmission efficiency >98%;
3. Reliable Braking: Disc brake structure with fast response and large braking torque, supporting heavy-duty frequent braking;
4. Strong Durability: Key components surface hardened, impact resistant, fatigue resistant;
5. Maintenance Friendly: Brake friction pads can be quickly replaced, gears lubricated for life.
Application Scope
1. Lifting Machinery: Hoisting mechanisms and luffing mechanisms of tower cranes, bridge cranes, and gantry cranes;
2. Conveying Equipment: Drive devices of belt conveyors and chain hoists;
3. Metallurgical Industry: Transmission systems of rolling mills and coilers;
4. Mining Machinery: Heavy-duty start-stop control of hoists and crushers;
5. Other Fields: Elevators traction machines, port machinery, construction machinery, and other scenarios requiring "transmission + braking" functions.
Working Principle
1. Transmission Process: The input shaft transmits torque to the output gear shaft through gear pairs, achieving speed reduction or increase. Gear meshing follows involute motion laws, ensuring smooth transmission and low noise.
2. Braking Process: When the equipment needs to stop, the brake activates (e.g., energized excitation or spring reset), pushing friction pads to press the brake disc (linked to the output shaft), achieving rapid braking through friction torque to prevent load rollback; braking control can be normally closed (power-off braking) or normally open (power-on braking), meeting different safety requirements.
