According to the different finished product standards of copper bushings can be divided into: Copper self-lubricating bushings, oil lubrication need to, graphite, copper, and other types of bushings. The raw materials for the production of copper bushings are also common: tin bronze, aluminum bronze, brass, phosphor bronze, etc. The casting method is further divided into: metal casting model, precision casting, centrifugal casting, sand casting. The existence of copper bushings is reasonable, and some mechanical designers may not like the existence of copper bushings, but often in the long-term actual use process, its advantages are slowly reflected!
Copper axle sleeve, also known as copper sleeve, is an accessory made of copper by casting. Used in machine work, it simplifies the structural manufacturing process by reducing mechanical friction, reducing vibration, corrosion, noise, and maintenance. At present, copper bushings are widely used in machine parts, but when faced with long-term machine operation, the copper bushings will have some wear and tear, and it will have a certain life. If its wear procedure reaches a certain level and affects the normal operation of the machine, it should be replaced in time. At the same time, because the cost of casting copper shaft kits is relatively cheap, it is currently widely used in the machinery manufacturing industry.
There are many functions of copper bushings. For example, it is multi-faceted, not only can reduce shock, but also can resist corrosion, but also can be isolated from toxic media, increase the service life of bearings. However, it is mainly used for sliding bearings. It can use bearings to withstand greater loads, plus the combination of lubricants, is the best partner for mechanical parts, especially for large and heavy-duty machines. In order to prevent the gear shaft from shifting due to vibration when moving, it is necessary to use a copper bushing for fixing.
Therefore, the important role of the copper bushing in the machine is to fix and position. Another function of the copper bushing is the function of the sliding bearing. In order to achieve cost saving, the thickness of the bushing is designed according to the axial load of the bearing. In fact, the copper bushing is also considered a kind of sliding bearing. It can be used to replace rolling bearings in some cases where the speed is relatively low and the clearance requirements are relatively high. The copper bushing is very wear-resistant and can be used for a long time, so it saves a lot of cost.
