Q:Is it good for rolling bearings of single cylinder diesel engines or for sliding bearings?: sliding bearing can be conveniently and the diesel engine oil lubrication system integrated with lubrication oil through the transmission oil inside the cylinder body.

Q:What are the aspects of the performance of plain bearing materials?: The material selection of the sliding bearing depends on the form of failure. The main failure modes are wear and fatigue damage of bearings and shafts. The prevention of wear and fatigue damage of bearings and bushings is the key to the selection of bearings and bushings. The main considerations are as follows:Wear resistance and friction reduction;Running in (running fit);Hiding property;Compliance;Strength and plasticity;The heat transfer and good corrosion resistance;The process of economy, etc..

Q:Thrust bearing principle: There seems to be no principle here. The spindle is thrust head and mirror plate, bearing on head and thrust, the thrust oil tank on the head of the lubricating oil base into tile gap cooling.

Q:What are the differences between rolling bearings and plain bearings? What are their respective applications?: So, in heavy load situations and requirements of the radial dimensions small, compact structure requirements of occasions (such as the crankshaft bearings, rolling mill, roller bearing) with sliding bearing; rolling bearing vibration and noise, so on The precision requirement is very high, and no vibration occasions, rolling bearings generally difficult to do, is a rolling bearing rolling body adopts the sliding bearing.x0d the main difference often (ball, roller, tapered roller, needle roller bearing), there is no difference between the rolling body.x0d rolling bearing and sliding bearing the first appearance of the structure on the rolling bearing is a rotating body by rolling to support the rotating shaft, which is a point of contact area, rolling body more, nine more points of contact; x0d sliding bearing is on the smooth surface to support the rotating shaft, which is a surface contact area.

Q:Is the high or low pair of plain bearings and shafts?: The element of the moving pair of sliding bearings is surface contact, which is low pair!

Q:Fan relatively loud, on-line check found that rolling bearings are best not to oil, sliding bearings can be oiled.I was depressed, I do not know what the fan is bearing.. in fact, the whole hardware blind.Which prawns can say that? It's better to compare the pictures above.. ThanksYes, the video card fan is too loud.. Considering changing?..Originally, I had only a heat sink.. Nothing, but the temperature is too high and the recent game fan.Had to buy 30 yuan. Because of the rush to buy.. The size is not found. The quality is so bad.. A small fan, mounted on a radiator.. My other fans don't have any problems.: There is basically no sliding bearing fan. In fact, it is simple to test whether or not to roll bearings: to blow a breath on the fan blades, and then to rebound when they stop, they are all rolling. No matter what type of fan can be oiled, this upstairs brother is quite right.

Q:One hundred and twentyAttention is the reason and purpose, the postgraduate entrance examination urgent need, thank you answer, after the exam will be re points, thank you!: If the average temperature of the oil exceeds the value set when calculating the carrying capacity, then the bearing capacity will decline or even fail, so the thermal balance calculation of the sliding bearing must be carried out.

Q:Generally speaking, the stiffness of the rolling bearings is more than the stiffness of the sliding bearings - the stiffness of the ball bearings is more than the stiffness of the roller bearings - -: Generally speaking, the stiffness of rolling bearings is lower than that of plain bearings, and the stiffness of ball bearings is lower than that of roller bearings! ~

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!: For example, where oil lubrication or grease lubrication is not possible.Scrolling high speed depends on the selected bearings.

Q:What will cause the friction coefficient to be inaccurate in a hydrodynamic sliding bearing?: The gap between the shaft and the hole, the shaft speed of these two factors is more critical, gap control is not good, there is no way to form a good oil film, that is, can not form a complete liquid friction
