Q:Which foreign brands are good for self lubricating sliding bearings?
Brand NSK, SKF, IGUS, OILERs, Canada, THORDON, USA, DRIE, etc.;Should say each has advantages, brand big words, the product is relatively expensive, product series of all words, not all kinds of products are fine;Like NSK and SKF, they now have self lubrication, but this is not their flagship product;
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:What are the properties of plain bearing alloys?
The sliding bearing alloy should have the ideal organization of both hard and soft:(1) soft matrix and uniformly distributed hard point.(2) a soft particle is arranged on the ideal tissue of the hard base sliding bearing alloy. When the bearing is working, the soft tissue is firstly worn down and sunken, and the lubricant can be stored to form a continuous distribution of oil film, while the hard component plays the role of supporting the journal. Thus, the actual contact area of the bearing and the shaft neck is greatly reduced, so that the friction of the bearing is reduced.(3) the sliding bearing alloy has sufficient compressive strength and anti fatigue performance; good performance for reducing friction (friction coefficient is smaller); reserve good lubricating function; good adaptability; good thermal conductivity and corrosion resistance; good process performance, which is easy to manufacture, low price.
Q:Sliding bearing rotor shaft neck, prone to wear and galling and what defects
Sliding bearing rotor shaft neck, prone to wear and galling and locking defects such as sliding bearing according to the production requirements, the general requirements of Rongchang sliding bearings on the shaft:Shafts require heat treatment.The shaft requires grinding and more than 0.8 finish.Refuel in good time.
Q:What is the speed of plain bearings?
The position of the oil free bushing is generally used for more accurate straight-line slip. But the rotation still gives priority to bearings. Or simply use linear bearings.
Q:Can the sliding bearings move in axial direction?
TolerableAskThere is no either circumferential movement or some axial motion to the frontal bearingThanksChasing the answerDoes the circumferential motion go to the forehead?
Q:What kind of lubrication is used for spindle bearings of important or precision machine tools?
2. universal grinder, internal grinder, grinding high speed grease for these two kinds of grinding roller bearing, the rolling bearing of high speed spindle, the spindle speed is 1000 ~ 20000r / min, according to the speed range, such as when the value is less than 1 * 106, choice of precision machine tool spindle grease (No. 3 high speed grinding grease) white grease or special grease. This kind of machine tool and bearing internal grinder similar rolling 3. universal thread grinder spindle, spindle rolling bearing structure for ball type, spindle speed range is different, such as spindle speed Y7520WDN universal thread grinder is 5745 ~ 18000r / rain, can choose 2 high speed spindle bearing grease, can also be No. 2 multipurpose grease. 4. rolling bearing gear grinding machine spindle gear grinder spindle speed, generally in the 1000 ~ 3000r / min, in the speed range, the rolling bearing can be lubricated by lubricating oil, also can be lubricated by grease, such as high speed spindle bearing grease No. 3 or No. 2 multi effect lithium base grease. Rolling bearings use N15 mechanical oil or 2 spindle oil lubrication, bearing noise, grinding head noise, grinding head temperature of 70~80 degrees, and the oil leakage is serious, bearing wear rate is high, affecting production. If the switch to general lithium grease, can eliminate the temperature rise, to avoid oil leakage, stable work, surface roughness from level 6 to level 7, and add the grease has been used to bearing scrap, can prolong the service life of 2~3 times of bearing. Improve the industry technology, can find some more and more school platform, such as Xin opportunity, or in the application market to try to search some metal processing related applications ~ hope to adopt.
Q:How to use the method of pressing lead wire check bearing bearing clearance?
Open the cylinder cover, the lead wire on the top of the piston, the cylinder head cover with cylinder head bolts, rotate the crankshaft piston across the TDC, then open the cylinder cover, take out the wire, the wire measurement is flattening of the size, this size is the piston top clearance.
Q:When calculating non liquid friction sliding bearings, what is the purpose of checking P, PV, v?
Check the average pressure of the bearing P is to ensure that the lubricant is not too large pressure extrusion.
Q:What are the causes of high temperature of plain bearings?
If it is too high, it is possible to confirm the load and lubrication of the bearing
