Wrapped Bronze Bushing: Small Component, Big Impact
Wrapped Bronze Bushing, is an important mechanical foundation parts, it will copper alloy sheet rolled into, in the surface can be rolled out diamond-shaped or hemispherical oil holes, oil grooves, etc., in order to store and gradually release the lubricant. Usually made of phosphor bronze CuSn8 and other tin bronze alloy, this material has high purity, few impurities, excellent wear resistance, corrosion resistance, fatigue resistance and high bearing capacity, can be - 40 ℃ to 150 ℃ within the temperature range of long-term stable work.
Production process
Adopting high-precision rolling process, we are able to roll the thin bronze sheet into the required shape and size, and ensure its precision and quality through calibration. Meanwhile, the design of oil holes and grooves on the surface is one of the key processes, and these
special structures can be used as oil reservoirs for lubricants, so that the bushing can continuously lubricate itself during operation.
Performance Advantages
- Self-lubrication: The oil reservoir structure on its surface can release a small amount of solid lubricant during operation, which combines with the tiny machining marks on the shaft to reduce the coefficient of friction, eliminating the need for frequent external refueling, and allowing it to work well in environments where oil is prohibited or less oil is present, avoiding environmental pollution.
- High load and shock resistance: wrapped bronze bushing can withstand high loads and shock loads, ensure the stability of mechanical running parts, provide solid support for the equipment, suitable for heavy loads and shock conditions.
- Wear-resistant and long life: the wear-resistant nature of the bronze material makes it effective in resisting friction and abrasion, prolonging the service life of the equipment and reducing the maintenance cost and downtime of the equipment.
- Corrosion resistance: In the humid, acid and alkali and other harsh environments, it can still maintain good performance, without additional anti-corrosion measures, to protect the normal operation of the equipment in complex environments.
- Strong resistance to impurities: in highly polluted environments, such as construction machinery, mining machinery and other fields, it can resist the intrusion of impurities and maintain stable lubrication effect and performance.
Selection and design points
- Adaptability to working conditions: according to the specific working conditions, such as speed, load, temperature, environment, etc., choose the appropriate Wrapped Bronze Bushing. e.g., in high speed, light load working conditions, you can choose the bushing with thinner wall thickness; while in low speed, heavy load working conditions, you need to choose the bushing with thicker wall thickness and higher strength.
- Shaft surface roughness: shaft surface roughness on the sleeve wear and lubrication has a great impact. Shaft surface is too rough will aggravate the wear of the sleeve, while too smooth may lead to poor lubrication, so according to the requirements of the sleeve need to choose the appropriate shaft surface roughness.
- Dimensional accuracy and fit: The dimensional accuracy of the fit between the bushing and the shaft, the bushing and the bearing housing directly affects the installation and operation of the bushing, which needs to be processed and assembled in strict accordance with the design requirements.
- Lubrication: According to the actual working conditions and equipment requirements, determine the appropriate lubrication method and lubricant type. For some special working conditions, such as high temperature, high load or underwater work, may need to choose a special lubricant or sealing structure to ensure the lubrication effect.
Industry Development Trends
- Material R&D: Continuously research and develop new high-performance bronze alloy materials to improve their strength, wear resistance and fatigue resistance and other performance indicators to meet the needs of more demanding working conditions.
- Process innovation: Adopt advanced manufacturing processes, such as high-precision rolling, precision machining, heat treatment, etc., to improve the production efficiency and quality stability of bushings and reduce production costs.
- Customized service: with the diversification of market demand, more and more bushing manufacturers provide customized service, according to the specific requirements of customers to design and manufacture bushing, to meet the individual needs of different equipment and working conditions.
- Intelligent development: with the help of sensors, Internet of Things and other technologies, to achieve real-time monitoring of the operating status of the bushing and fault diagnosis, early warning and deal with potential problems, improve equipment reliability and operational efficiency, reduce maintenance costs.
