- Q: Why are the bearings on the crankshaft of the engine sliding bearings? So high speed, sliding bearings friction is not great?? Fever will not be great? Please prawns in detail, thank you
- The reasons are as follows:The main reason is that the sliding bearing sleeve is two pieces, so it can be installed on the crankshaft. The rolling bearing can not be installed on the crankshaft.The utility model has the advantages of simple structure, low cost, easy lubrication, convenient installation, easy sealing, low noise and high precision. As long as the material pass, wear little.In addition, for a precision problem, nor is it suitable for other bearings.As for other places, both work speed, noise, work conditions, rotation accuracy, withstand shock, vibration ability, maintenance is not the same. The sliding bearing has the characteristics of high bearing capacity, good seismic resistance, low noise, long service life, etc. the rolling bearing has the characteristics of shock, vibration, noise and sealing. Rolling bearings are standard parts, easy to change. Plain bearings consume nonferrous metals.
- 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!
- Objective: the heat balance calculation is designed to limit the inlet temperature of the lubricant so as to ensure the normal operation of the sliding bearings
- 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: What is the bearing force value, how to determine, how to adjust, what is the effect?
- Bearing preload value of the end is lower level put a root diameter of 1mm length 100mm wire (A1, A2), motor or pump mechanical corresponding middle bearing upper same diameter and length of wire (B1), and then fasten the bearing shell and lid, with a screw tightening, then open remove the flat wire, so the bearing force value of s=b1- (a1+a2) /2, mm.
- Q: The study on the friction and wear behavior of thrust bearings under oil lubrication conditions at home and abroad, their significance and future prospects!!!! The best reference source. Thank you if there are similar can be sent to my mailbox.
- Thrust sliding bearing: a sliding bearing that bears axial thrust and restricts axial movement of the shaft. Two, the friction surface is completely separated by the fluid film thrust bearings, divided into fluid dynamic thrust bearings and hydrostatic thrust bearings, suitable for high speed operation. Two a thrust bearing whose surface is not completely separated by a fluid film operates under boundary lubrication and is only suitable for low speed operation.
- Q: it is better to have pictures of 6000V motors at both ends of the bearing what is called?
- Rolling bearings, whether ball bearings or roller bearings, in the absence of load point contact, sliding bearings are surface contact, and no relative movement, in short, a lot
- Q: What are the main applications of plain bearings?
- In order to improve the friction properties of the bearing surface, the antifriction material layer, which is cast on its inner surface, is called the bearing lining. Bearing and bearing lining materials are collectively referred to as journal bearing materials. The application of sliding bearings is usually under the condition of high speed and light load.For example: construction machinery, marine equipment, water conservancy projects, aviation, aerospace, railways and other fields.Compared with rolling bearings, plain bearings have the characteristics of high bearing capacity, good seismic resistance, stable and reliable operation, low noise and long service life.
- Q: What kind of lubrication is used for spindle bearings of important or precision machine tools?
- The spindle bearings of precision machine tools are lubricated by grease, and usually use No. 2 multi effect lithium base grease. Some of them can last for 3~5 years or more. Most of the time in lithium grease foreign precision machine tool bearings, rolling bearing until scrapped, does not need the grease. The spindle bearings of precision machine tools usually have three structural forms, such as roller, roller cone and ball roller. The structure of different forms of grease requirements, such as roller bearing and spindle fit, should use the grease base oil viscosity is low; at high speed and low load, should use grease low consistency; at low speed and high load, with high consistency grease. Precision machine tool spindle speed rolling bearings and shaft diameter is an important basis for the selection of grease materials, when the bearing inner diameter of D (Im) and n (R / min glaze revolution) the product of DN is less than 0.6 * 106, with grease. When the DN value of the rolling bearing reaches L x 106, it is lubricated with "oil mist". When lubricated with lubricating oil, it is approximately the same as the sliding bearings.
- Q: For sliding bearing, bearings, bushings, bushing and difference function
- The bushing is mounted on the shaft, with the shaft to rotate together. The Bush is mounted on the seat and does not rotate.There are many large shaft to achieve part of high hardness and high wear resistance with the invention and bearing bushes, but since a high frequency quenching and surface treatment process after these basically eliminated.
- Q: The greater the fuel consumption of a sliding bearing, the greater or smaller the heat?
- How can bearings burn oil? It's not an engine
