- Q: Cooling method and structure of sliding bearing
- The so-called water cooling, that is, on the bearing body slot, can pass cooling water, the effect is better.
- Q: The sliding bearing is an oil film formed between the inner surface and the journal. Is there a relative sliding between the outer surface and the hole on the connecting rod (such as the small end of the crank of the engine)? Between the internal surface and the shaft neck is very slippery, so that the axial fixed, will not fall out in the axial? Rolling bearings with nuts and retaining rings from the axial block the inner ring to prevent it from moving in the axial direction, sliding bearings is the same?As you can see, what kind of sliding bearings should be used in this case? What about the bush or the one with the flange or something else? How do you fix it in the axial direction?
- The sliding bearing (bushing) is axially fixed: 1. through interference fit. 2. step type sliding bearing fixing.
- Q: What effect does the sliding bearing have on the top gap?
- The top gap is normally pressed by lead. The top clearance is 1/1000 or 1/1000 of the axle neck, and five of the gap is 1/2 of the top clearance.
- Q: What are the advantages and disadvantages of plain bearings compared with those of rolling 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 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.3. 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 bearing.Bearing materials should have small coefficient of friction, good thermal conductivity, small coefficient of thermal expansion, wear resistance, corrosion resistance, strong adhesive resistance, sufficient mechanical strength and plasticity.(3) requirements for bearing materials: bearing alloy (Babbitt), bronze, bearing materials of special properties, etc..4. thrust plain bearings (understood)(1) the thrust bearing fixed and tilting.(2) the thrust surface of thrust bearing can use the end surface of the shaft, or can make a convex shoulder or thrust the disc in the middle of the shaft.(two) types and characteristics of rolling bearings1. classification of rolling bearingsAccording to the shape of the rolling body is divided into: ball bearings, roller bearings.2. characteristics of rolling bearings(1) advantages:Compared with plain bearings, rolling bearings have the advantages of small frictional resistance, quick starting, high efficiency, simple lubrication and easy replacement.(2) shortcomings:Low impact resistance, noise at high speed, and less working life than liquid lubricated sliding bearings.
- Q: What are the most afraid of sliding bearings?
- Sliding bearings are surface contact, so between the contact surface to maintain a certain oil film, so the design should pay attention to the following problems:1, it is necessary to smooth the oil film into the friction surface.2, oil should be from the non load area into the bearing.3, do not make the whole ring oil tank in the middle of the bearing.4, such as oil tile, joint opening oil groove.5. Make the oil ring fully and reliably supplied to the oil.6, the filling hole not blocked.7, do not form an oil free flow zone.8, to prevent cutting off the sharp edges and edges of the film.
- Q: What are the failure modes and design criteria for non liquid friction sliding bearings?
- Failure form: wear, scuffing.Design guidelines: maintenance of the boundary membrane is not damaged, minimize the wear of bearing materials.Relative condition checking1 checking: PM = [p], to prevent excessive bearing abrasion;2 checking: PMV = [pv], in order to prevent the bearing temperature rise too high and glue and;
- Q: In general, what kind of sliding bearing material is used in the case of large load?
- An argument that supports the first floor! At the same time, there are many sliding bearings to choose from, and different engineers have different designs!
- Q: How is the axial clearance of plain bearings large?
- Adjust the ring gasket by adjusting the outer bolster of the tile.
- Q: Sliding bearing lubrication, under what circumstances need throttling?
- Save the utility can adjust the lubricant pressure to provide lubricating oil bearing agent with membrane response of the bearing capacity and stiffness, and can maintain a constant, so that the lubricating oil change, lubricating oil can improve the pump like nuclear nuclear power station
- Q: What is Babbitt, bearing pad why plating Babbitt.
- Babbitt is the most widely known bearing material, and its application dates back to the industrial revolution. Babbitt is only suitable for relative to the low hardness of shaft material, compared with other bearing material, has better adaptability and swaging, widely used in large marine diesel engine, turbine, generator, and other large rotating machinery. Babbitt alloys can be simply divided into three types: high tin alloys, high lead alloys and intermediate alloys (both tin and lead in alloys are very important). In all these alloys, both antimony and copper are important alloying elements and hardening elements, and the structures are composed of hard intermetallic compounds dispersed in the soft matrix
