Application and Analysis of Oil-Lubricated Bearings in Tower Cranes: The rapid growth of high-rise buildings in recent years has significantly increased the demand for tower cranes, outpacing factory production capacity. To boost productivity and reduce costs, we aim to utilize standard parts instead of custom components, which shortens manufacturing cycles and stabilizes quality. Among these parts, the climbing claws and jacking rollers in the tower crane’s jacking frame typically use cast copper alloy bearings. However, the rising cost of copper has led some manufacturers to switch to cast iron sliding bearings to cut expenses. These sliding bearings, while cheaper, can struggle under heavy loads, risking lubrication loss and making them susceptible to breakage from external forces. Such failures can compromise support during the jacking process and potentially lead to safety incidents. Therefore, adopting standard oil-free lubricated bearings can provide the same bearing capacity and lubrication as cast copper bearings while achieving the cost-effectiveness of cast iron bearings. This approach allows for cost savings in both processing and materials while ensuring the safe operation of tower cranes.

To utilize oil-free bearings in tower cranes, we conducted a verification analysis focusing on their application characteristics and material structure. Oil-free lubrication enhances self-lubrication, wear resistance, and has a low friction coefficient, leading to a longer service life. These bearings exhibit excellent running-in performance, low noise, and no pollution, while their transfer film protects the grinding shaft. They also possess adequate elastoplasticity to distribute stress over a larger contact area, improving bearing capacity, especially for heavy loads at low speeds, where maintenance is impractical.

Oil-free bearings consist of a three-layer composite material comprising low-carbon steel, a porous bronze layer, and a PTFE-lead mixture on the surface. The PTFE-lead layer (0.01-0.03 mm) forms a wear-resistant transfer film, while the copper powder layer (0.2-0.35 mm) enhances bonding strength and thermal conductivity. The low-carbon steel (2-2.3 mm) increases bearing capacity, and a 0.002 mm copper/tin electroplating layer provides corrosion resistance.

The physical and mechanical properties of oil-free bearings were evaluated, and our analysis revealed that the selected oil-free bearings meet or exceed the maximum allowable values for pressure (P), maximum linear speed (V), and maximum PV value. This selection significantly reduces processing and material costs, as the cost of oil-free bearings is only 10% of cast copper alloy bearings.

In practical application, oil-free lubricated bearings in the tower crane’s climbing claws and other components bear substantial loads. For instance, the climbing claws support a working load of approximately 630,000 N. The specific pressure limit calculation shows that oil-free bearings can handle the required load, confirming their suitability.

The oil-free bearings for other parts, including the pulley at the tower cap and guide rollers, also passed pressure limit checks, demonstrating their reliability under varying load conditions. The maximum linear speeds across the tower crane’s components are all below 2.5 m/s, satisfying operational requirements.

Lastly, the PV values confirm that oil-free bearings are designed to ensure longevity. After nearly two years of use, the transition from cast copper alloy bearings to oil-free lubricated bearings has proven successful, with no failures or repairs needed. This change not only reduces processing and material costs significantly but also improves safety performance by maintaining lubrication requirements on construction sites, making oil-free bearings ideal for medium and low-speed, heavy-load conditions in tower cranes.

Technical Field: The self-lubricating bearing for container port cranes falls within the mechanical transmission domain.

Container port cranes are vital heavy machinery in the manufacturing industry, traditionally relying on copper alloy bearings. Regular lubrication and maintenance of these bearings, often required at high altitudes, can be inconvenient and, if neglected, may lead to mechanical failure due to insufficient oil lubrication. These challenges hinder the optimization and enhancement of port cranes. As a leading producer of container port cranes globally, China supplies many major international ports with its products. To advance the technology in container port cranes, reduce the inconvenience of high-altitude refueling, minimize oil pollution, and enhance equipment cleanliness, there is an urgent need for a bearing structure that is high-strength, self-lubricating, wear-resistant, and flexible. This new self-lubricating bearing can save up to 80% of non-ferrous copper compared to traditional options.

The utility model aims to provide a specialized self-lubricating bearing for container port cranes characterized by high structural strength, excellent self-lubrication, superior wear resistance, flexible operation, and material conservation. This is achieved using high-quality carbon structural steel for the shaft sleeve matrix, which is sintered with at least one layer of CuB10Sn10 copper alloy. The copper alloy layer features diamond-shaped oil holes filled with graphite. The bond between the matrix and sintered copper alloy layer is molten during manufacturing, and the sleeve is designed with a flange and lap technique, secured via carbon dioxide gas shielded welding. The friction working surface of the inner shaft sleeve is sprayed with a layer of MoS2.

This design boasts high technical content, substantial load capacity, wear resistance, self-lubrication, maintenance-free operation, and significant savings on copper materials. This specialized bearing is a key component in the machinery manufacturing sector, providing an ideal replacement for traditional sliding bearings in heavy-load, low-speed applications. Additionally, it can be applied in engineering, mining, metallurgical, and other machinery manufacturing fields, combining the strength of steel with the low friction of a sintered copper alloy. The embedded graphite and sprayed MoS2 enhance self-lubrication and wear resistance.
