1. Slewing bearing

The slewing bearing is a critical load-bearing component that enables relative rotation between machine parts while simultaneously handling axial, radial, and overturning moment forces. Its compact and lightweight design, made from high-strength alloy steel, ensures smooth operation with high precision (±0.05° rotation accuracy) and long service life. Key configurations include mounting bolt holes, optional internal/external gears, lubrication ports, and sealing systems for enhanced reliability. With a diameter range of 300–5000mm and load capacity up to 50,000kN, it is widely used in construction machinery, wind turbines, cranes, and military equipment. Custom designs are available for specialized applications.

2. Gear

1). Reverse gear

Generally, the turning angle of the turning gear is 0 °to  90 °. The function of displacement is achieved by turning the table.

2). Reverse gear

Gears are toothed mechanical components that transmit torque through meshing engagement with other gear elements like racks, worms or additional gears, enabling precise control over power transmission by modifying speed/torque ratios, redirecting motion paths, and converting motion types (e.g., rotary to linear). Their interlocking teeth design provides reliable force transfer while allowing for customizable mechanical advantage in various industrial applications.

3.Reducer

Gear reducers are mechanical power transmission devices that utilize precision gear systems to reduce input speed while proportionally increasing output torque, with the output torque being the product of motor torque and gear ratio (without exceeding the reducer’s rated capacity). These systems simultaneously decrease load inertia by the square of the reduction ratio, enabling optimized power conversion for various industrial applications through efficient gear engagement.

Welding Turntable Maintenance Guidelines

Core maintenance content

Daily maintenance-cleaning welding slag, checking lubrication and electrical safety.

Regular maintenance-tighten bolts, check transmission mechanism and test safety function.

Deep maintenance-annual replacement of worn parts, re-lubrication and system calibration

Fault early warning-Stop immediately when abnormal noise/uneven rotation occurs.

Maintain value

• Extend the service life of equipment by more than 30%
• Reduce sudden downtime
• Ensure the stability of welding accuracy.
