Manifold is a machine maintenance in one of the most important elements. The role of asphalt is: 1. To make direct contact with two rigid surface area of the smallest, thus reducing the wear of two surfaces. Reduction due to wear, damage to small machine precision, greatly reducing energy consumption. 2. Since the mobility of oil line, the heat generated by the machine parts are the oil away, so that the work of the machine is always within the normal temperature (not cause thermal deformation) to ensure the accuracy of the machine's drive. 3. Anti-corrosion. As the oil component surface always exists, so that air and surface components separately, to prevent oxidation reaction. In particular, high-speed moving parts of this demanding, because the surface temperature is high, more prone to oxidation. 4. Sealing effect. As part surface of processing errors, so there is always space between the two surfaces exist. If two surface oil is present, the two surfaces can be formed without gap condition. 5. Increase the contact area between the components, so that the machine running smoothly. Parts surface machining error is always there, so the contact area between components can not achieve 100 percent. The higher surface roughness, the less contact area, smooth operation of the worse. If the oil exists between the two surfaces, two surface contact area is greatly increased, making the machine run stable. The role of oil line can be seen from the important position of oil circuit. Oil as the blood, as there is no oil in the machine and no blood can not imagine the same person. 1 , Oil works Why oil will play the role? The following analysis of their works. Figure 6.l shown above following the movement of objects relative objects, the first is to be worn on both sides of the peak, when the two surfaces of the contact area. Greater. Further relative movement of the increased heat generated by the two surfaces, and heat slowed down, making contact with the surface temperature increased mobility of the metal to cause between the two sides together. Then if the relative motion of the two sides to continue, you need more power, so they produce more heat, the temperature increased further, taking together the metal continued to grow. So back and forth until the two sides of the contact surface to form a whole, relative motion can not be far. Figure 6.1 Oil in the contact surface after joining, then the situation will improve, as shown in Figure 6.2. Figure 6.2 Relative movement of the contact surface is ground off both sides of the peak, the formation of the situation shown in Figure . Relative motion to continue, because there is oil there. Do not touch the upper and lower sides so that the two free surface wear, transmission accuracy is guaranteed. Most of the friction interface is the medium for oil, the friction heat generated is pumping away. The role of oil in here can be summarized in two points: 1. Separation of two contact surfaces, so that the two indirect contact with contact surface; 2. Cooling, the temperature of the contact surface to maintain the minimum. Although the contact area needs refueling, but generally do not leave space for oil, the contact surface machining error is enough to ensure film formation.
