Q: What is a sliding bearing alloy?: 3, enough plasticity and toughness, higher fatigue strength; 4, good heat resistance grade corrosion resistance; 5, good running in.

Q: where is it used in general, and some concrete examples are given: The self-aligning ball bearings, used in the shaft and the bearing chamber is not concentric, many mechanical equipment are used, but the standard load is relatively small, if the load is large, recommend the use of self-aligning roller bearing, I hope to help you

Q: What are the conditions for forming sliding bearings and dynamic oil film lubrication?: Conditions for lubrication of hydrodynamic oil film for sliding bearings:1, must have an oil wedge to form a dynamic pressure, to ensure equal access to oil;2, the thrust plate relative motion to form convergent wedge on the pad;3, the viscosity of the oil is right, the amount of oil appropriate.

Q: What's the difference between plain bearings and oilless bearings?: Compared with plain bearings, the advantages of rolling bearings:1, the general condition, the rolling efficiency and hydrodynamic bearing lubrication bearing, but higher than the mixed lubrication bearing; 2 radial clearance is relatively small, the centripetal angular contact bearing preload available available pretightening force to eliminate the clearance, operation and high precision; 3, for the same size of the shaft diameter, bearing width ratio the sliding bearing is small, the axial structure of machine is compact; 4, most of the rolling bearing can be both radial and axial load, the bearing assembly has the advantages of simple structure, less consumption of lubricants;

Q: Effect of bearing speed on oil film stiffness of journal bearings: The shaft and bearings are in direct contact. Is there an oil film at this time?! It is true that the eccentricity decreases and the stiffness decreases. But in the front, it depends.

Q: What are the methods of casting plain bearings?: Usually to the metal materials company purchased bearings, bearing bronze (or called Babbitt), many are scrap copper, the use of crucibles, casting sand.

Q: What are the properties of plain bearing materials? Are there any materials that can satisfy these properties simultaneously?: A) the types and characteristics of sliding bearing sliding bearing according to the 1. loads are divided into: (1) sliding bearings (radial sliding bearing); mainly bear radial load; (2) the thrust bearing, main bearing axial load. 2. sliding bearings are suitable for low speed, high precision, heavy load and structural requirements. It is also used at low speed and impact.

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: Hello, about the bearing problem. Sliding bearings are made of powder metallurgy. What kind of grease does it use?: Powder metallurgy bearing is lubricated bearings in the factory will be through the vacuum method of negative pressure adsorption added lubricating oil, in the late stage of the process slowly release and consumption, good quality of powder metallurgy bearing life can reach more than ten years.This type of bearing is recommended to not add lubricating oil or grease, add after will have to change the bearings of the environment, such as dust adhesion, friction coefficient change, oil smoothly, when oil was crushed, and the lubrication performance of powder metallurgy bearing itself and do not come out to play, will become very astringent a card, caused by poor lubrication, which often needs to be added, resulting in unnecessary consumption and fee of manpower. Of course, there is a powder metallurgy sliding bearing is not oily, there is grease, add glib, this is often need to add fat.

Q: What are the technical requirements and precautions for the assembly of plain bearings?: When the shaft rotates at a high speed, the shaft to the bearing with periodically varying load, sometimes accompanied by shock.
