FAW CONNECTING ROD BUSHING DESCRIPTION
FAW CONNECTING ROD BUSHING is used for mechanical parts to achieve sealing, wear protection and other supporting parts, refers to the role of the liner ring. In the valve application field, the bushing is inside the valve cover, usually using polytetrafluoroethylene or graphite and other corrosion-resistant materials for sealing purposes.
In moving parts, the wear of parts is caused by long friction. When the gap between the shaft and the hole is worn to a certain extent, the parts must be replaced. Therefore, the designer chooses the lower hardness and wear-resistant material as the FAW CONNECTING ROD BUSHING when the design is designed, which can reduce the wear of the shaft and the seat, when the bushing or bushing is worn out. To a certain degree of replacement, this can save the cost of changing the shaft or seat, generally speaking, the bushing and the seat use the interference fit, and with the shaft with the gap, because no matter how or not to avoid wear, it can only extend the life, and the shaft parts are relatively easy to process; there are some new design. The plan personnel do not like this design, think this is to increase the cost in the manufacture, but after a period of use, the maintenance still should be modified according to this method, but the transformation is easy to cause the precision of the equipment to reduce, the reason is very simple, the two processing is unable to guarantee the position of the heart in the seat hole, the shaft sleeve is in one. Some places with lower rotational speed, higher radial load and higher clearance (such as convex axle) are used to replace the rolling bearing (the shaft sleeve is also a sliding bearing). The material requires low hardness and wear resistance. The inner hole of the sleeve can be grinded and scraped to achieve high coordination precision. The inner wall must have oil tank and shaft sleeve. Lubrication is very important, if dry grinding, shaft and shaft sleeve will soon be scrapped. Here, the hole wall of the shaving shafts is recommended. In this way, many small pits can be left, and the lubricating bushing and shaft sleeve are selected to choose different types according to the different working conditions. The main conditions are: pressure, velocity, pressure velocity product, lubrication state and load property.
