Q:sliding bearing: There is a fundamental difference between plain bearings and rolling bearings.The rolling bearings bear the weight by the ball bearings, and the contact between the friction pairs is unavoidable, and the wear is unavoidable. Just imagine how many tens of tons of rotating shaft, 3000 rpm per minute, if rolling bearings can hold for how long?The static and dynamic parts of the sliding bearing are not in direct contact. When rotating at high speed, the rotating shaft is raised by a high pressure oil film to form a suspension state. So, as long as properly used, sliding bearings can carry dozens of tons of rotating shaft, continuous operation thousands of tens of thousands of hours.

Q:What are the properties of plain bearing alloys?: 1, enough strength and hardness;2, high wear resistance and small friction coefficient;3, enough plasticity and toughness, higher fatigue strength;4, good heat resistance grade corrosion resistance;5, good running in.

Q:What are the consequences of not hammer sliding bearing: Tapered roller bearings, spherical roller bearings and thrust roller bearings, because at the same time subjected to radial and axial load, so in the same temperature, the ratio of ball and cylindrical roller bearings with high viscosity lubricating oil {TodayHot}. At constant speed, under the condition of normal temperature, tapered roller bearings and spherical roller bearings, oil viscosity is the lowest limit for the mechanical oil viscosity of AN32 - L. Spherical roller thrust bearings oil viscosity is the lowest limit for the mechanical oil viscosity of AN46 - L.Because of the larger sliding friction, the needle roller bearings need more effective lubrication, so the viscosity level of the oil is usually lower than that of the ball bearings of the same specification and speed.For plain bearings, the viscosity of the oil is related to the journal diameter, the rotation speed of the shaft, and the magnitude of the load per unit area.

Q:Now the self-lubricating sliding bearings can withstand the high speed, and if the speed is 30000 rpm, what kind of sliding bearings are chosen?: 30000 rpm, very high speed, it is recommended to have angular contact, such as 7206. I wonder if you used that model. Can you say the next model?

Q:On what occasions are plain bearings used?: 3, heavy load occasions;4, under the condition of tremendous impact and vibration;5, need to be made into split bearing occasions;

Q:Sliding bearings relative clearance 0.001 what?: The so-called relative clearance, refers to the sliding bearings of the Bush and bushings, nominal size tolerances can be large or small, but the gap between each other can only be 0.001.

Q:What's the difference between rolling and plain bearings? What is Bush? What do you mean by scraping the Bush? How to operate?: The difference between rolling bearing and sliding bearing the first appearance of the structure, 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; sliding bearing is on the smooth surface to support the rotating shaft, which is a surface contact area.

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:What's the difference between plain bearings and oilless bearings?: The sliding bearing has the following characteristics: 1, long service life, suitable for high speed; 2, can withstand the shock and vibration load; 3, high running precision, work balance, no noise; 4, simple structure, convenient assembly and disassembly; 5, large carrying capacity, can be used for heavy-duty; 6, non friction sliding friction bearing liquid. Loss of fluid friction; sliding bearing, rolling bearing friction loss and not much difference, but the design and manufacture of lubrication and maintenance requirements of high.

Q:Is the ultra high speed spindle suitable for sliding bearings?: (1) types and characteristics of plain bearings1. the sliding bearings are divided according to the load:(1) radial sliding bearing (radial sliding bearing), mainly bearing radial load;(2) thrust bearings are mainly subjected to axial load2. sliding bearings are suitable for low speed, high precision, heavy load and structural requirements. They are also used in low speed and impact occasions3. center journal bearing(1) integral type and split fractionThe splitting is usually made up of bearing cap, bearing seat, bearing bush and connecting bolt(2) the Bush is the key part in the bearingBearing materials should have small coefficient of friction, good thermal conductivity, small coefficient of thermal expansion, wear resistance, corrosion resistance, anti scuffing ability, sufficient mechanical strength and plasticity(3) requirements for bearing materials: bearing alloy (Babbitt), bronze, bearing materials of special properties, etc.
