Q: What are the bearing capacity of the bearings when they are discharged at the end?: Consider the end discharge and the coefficient of influence at the end of the discharge.

Q: What are the factors associated with the oil film pressure of dynamic sliding bearings?: 1) a convergent wedge gap must be formed between the two surfaces that are relatively sliding

Q: What are the ways to flush bearings?: 2. shaft and bearing housings, holes and other parts of the cleaning, first with gasoline or kerosene cleaning, dry cloth clean, and then coated with a small amount of oil in order to install. These parts after cleaning, should pay attention to where the casting sand is to completely remove all burrs and sharp edges; bearing parts, must be removed, to avoid residual sand and metal debris when installed into the inner part of the bearing, affecting the quality of assembly. 1., attention to the internal, outer ring separable bearings, do not change the outer ring each other wrong, so as not to affect the quality of contact. On the ball and roller bearings, roller bearings shall be arbitrarily put out in the mix, so as not to affect the accuracy of the installation position. When installing the bearing, in order to easily observe the bearing code number, not to be wrong, the bearing rings should be typed outside and installed. The shell hole 2. bearing and bearing seat heating for a large amount of surplus and large bearing, in order to facilitate the installation, must be installed before heating; for light metal bearing shell hole tight fit (such as aluminum bearing), due to very low hardness, surface to prevent bearing outer ring press bearing shell hole the scratch and galling, should also be heating installation. Heating method, usually bearing or separate bearing ring into the tank with clean oil, so that oil flooded bearings, uniform heating. When the temperature reaches 80 - 90 degrees, remove the heat and install it while the heat is hot. The tank made available 2 3mm thick plate, from the bottom 50 70mm height with a porous plate, bearing in porous plate heating. The aim is to prevent the precipitation of impurities in the oil into the bearings. However, for both bearings with a dust cover or seal ring, the lubricant cannot be heated at the beginning of the installation because of the lubricant used in the manufacture.

Q: How to determine the axial clearance and expansion clearance of plain bearings?: The 2. clearance fit is the fit of the clearance (including the minimum clearance equal to zero) when the hole is in alignment with the shaft, where the tolerance of the hole is above the tolerance band of the shaft. The function of gap is to store oil and compensate various errors, and the magnitude of which affects the relative movement of the hole and axis. The clearance fit is mainly used for the movable connection between the holes and shafts, such as the connection of the sliding bearings and shafts.

Q: In power plants, are the bearings used in turbines rolling or plain bearings?: Of course, sliding bearings, the advantages are: (1) good bearing, pressure (2), large contact surface, wear resistance (3), good fixation, to prevent rotation when the axis deviation from the wear and tear, and the occurrence of an accident.

Q: 10kV High Voltage Motor how to distinguish between rolling and sliding bearings, preferably pictures: If it is a rolling bearing, the motor can be turned with a little force, and the sliding bearing will not rotate without the oil supply.

Q: They are three, who has a relative movement with whom, who is relatively static between them? What are their order from inside and outside?: The bearing bush is a kind of plain bearing. The axle diameter refers to the diameter of the axle.

Q: In what circumstances is it better to use a sliding bearing than a rolling bearing?: but the rolling of metal debris and other foreign bodies are particularly sensitive to the rolling bearing life shorter than the sliding bearing, bear the load bearing capacity than the same volume of plain bearings is much smaller, because of this, the radial bearing large size. So, in heavy load situations and requirements of small radial size, requires compact structure occasions (such as the crankshaft bearings, rolling mill, roller bearing) with sliding bearing; rolling bearing vibration and noise, therefore, very high precision, and no vibration occasions, rolling bearing is general competent, often used in sliding bearing.

Q: Why does the sliding bearing use clearance fit?: This is different from the rolling bearings, the shaft and rolling bearings of the inner ring is interference fit, because the shaft should be rolling bearing with the inner ring together to rotate.

Q: The greater the fuel consumption of a sliding bearing, the greater or smaller the heat?: Hematemesis, wrong words can not talk.The book said: "the width to diameter ratio, the carrying capacity decreased, fuel consumption increased, the temperature drop.".Although the relationship between fuel consumption and temperature rise is unknown.
