Q:What are the requirements for the material performance of plain bearings?
When the machine does not work, the axle is resting on the bearing and exerts pressure on the bearing. When the shaft rotates at a high speed, the shaft to the bearing with periodically varying load, sometimes accompanied by shock. The basic function of plain bearings is to accurately locate the shaft and to support the shaft without damaging it under load. Shafts usually cost higher and are often uneconomical to replace. Selecting the bearing alloy that meets certain performance requirements can guarantee the minimum wear of the shaft.
Q:What effect does the sliding bearing have on the top gap?
There must be a gap between the clearances.The fit between the sliding bearing and the shaft is clearance fit. The top gap is normally pressed by lead. The top clearance is 1/1000 or 1/1000 of the axle neck, and five of the gap is 1/2 of the top clearance.
Q:What is the difference between rolling bearings and plain bearings?
Plain bearing: a sleeve made of copper or porous iron (or copper) material. It has many kinds of structures. Rolling bearings, also called ball bearings, are made of steel balls. The shape and material of the two are obviously different
Q:Sliding bearings can be used for structural requirements on opposite occasions
3. radial sliding bearing (1) integral and split division is usually made up of bearing cap, bearing seat, bearing bush and connecting bolt. (2) the Bush is the key part in the bearing. Bearing materials should have small coefficient of friction, good thermal conductivity, small coefficient of thermal expansion, wear resistance, corrosion resistance, strong adhesive resistance, sufficient mechanical strength and plasticity. (3) requirements for bearing materials: bearing alloy (Babbitt), bronze, bearing materials of special properties, etc.. 4. thrust bearing (understand) (1) thrust bearing fixed and tilting. (2) the thrust surface of thrust bearing can use the end surface of the shaft, or can make a convex shoulder or thrust the disc in the middle of the shaft.
Q:If the minimum oil film thickness is not large enough, which measures are most effective: reducing the width to diameter ratio; increasing the oil supply; reducing the relative gap; increasing the eccentricity. And explain the reasons
Increasing oil supplyThe gap can only be increased by increasing the flow of oil through the lowest oil film thickness.
Q:What are the differences between rolling bearings and plain bearings?
Two, compared with the sliding bearing, deep groove ball bearings shortcomings:1, vibration and noise;2. Radial dimensions larger than plain bearings;3 、 poor ability to withstand impact loading;4 、 under high speed and heavy load, the bearing life is low.
Q:I recently learned some knowledge of rolling bearings and journal bearings. Questions to ask the experts:1, sliding bearings for high speed, heavy load, then in reality, how many high speed, large load sliding bearings?2, in addition to the speed and load, rolling bearings and sliding bearings at the choice of, there are other considerations? Such as price.3, rolling bearings can withstand the maximum speed is generally how much? Such as 7000RPM or 10000RPM.Relatively superficial problem, may not ask the key point, but also ask you to forgive me, thank you!
The specific choice is usually to see the design needs. Plain bearings generally consider heavy loads or poor lubrication conditions.
Q:Bearing bearing belongs to what type of
Bearing bearing belongs to the type of internal combustion engine.The bearing of an internal combustion engine is a sliding component in the sliding bearing of an internal combustion engine. The shape of the Bush is a semicircle cylinder shaped like a tile, called a bush. Because of the heavy weight of the internal combustion engine shaft, the needle roller (bead) bearings can not be used, but only sliding bearings can be used.When the sliding bearing is working, a thin oil film is required between the Bush and the rotating shaft to lubricate the sliding bearing. If due to bad lubrication, there is direct friction between bearing and shaft friction will produce high temperature, while the bearing is due to the special high temperature resistant alloy material, but high temperature direct friction on the burn is still. The Bush may also be burnt due to excessive load, high temperature, impurities or abnormal viscosity of lubricating oil. The plain bearing is damaged after burning the tile.The bearing load in the bearing is composed of sliding bearings, so called single sliding bearing them there is no difference, as Bush is concerned, in order to reduce friction and wear, so use copper alloy, copper base aluminum tin alloy, tin alloy, Babbitt and so on, they are not standard.
Q:What are the causes of high temperature of plain bearings?
What is the actual temperature? The bearing tells the rotating part, and the more than 100 degree is normal
Q:What's the connection between the crankshaft and the sliding bearings?
The crankshaft is the shaft, the Bush is tile, the upper and lower two pieces of tile and together is the sliding bearing, can serve as the support of the crankshaft.
