- 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:What are the structures of journal bearings, rolling bearings or plain bearings?
- The structure of journal bearing is similar to that of deep groove bearing. Most of the applications are radial load bearing, and the shaft is often very short, and even the inner ring is directly connected with the inner ring of the bearing. Some outer ring in accordance with the shape of the machine tool rail surface. The name of the journal bearing probably comes from this!
- 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:Are the motors sliding bearings at both ends?
- In general, both ends of the motor are using deep groove ball bearings, large motors such as 1000KW or more will generally use sliding bearings, also known as bearing.
- Q:What's the difference between plain bearings and oilless bearings?
- 5, easy sealing, easy maintenance; 6, do not need useful non-ferrous metals; 7, high degree of standardization, mass production, low cost.Compared with plain bearings, the disadvantages of rolling bearings:1, the ability to withstand shock loading is poor; 2, high speed and heavy load bearing life is low; 3, vibration and noise is larger; 4, radial size than sliding bearings.
- Q:What are the parameters of maximum bearing capacity factor Cp of plain bearings?
- Specific pressure, speed, viscosity of lubricating oilCp is a dimensionless parameter that describes the bearing capacity of a bearing. For a specific bearing, under certain load F, the journal will be balanced in a certain position of the bearing (a certain offset e, a certain deflection angle), that is, in a stable working state. When the load F changes, the journal will move to the new equilibrium position.
- Q:Maintenance method of plain bearing
- The repair method is wrong and the installation is wrong. Use improper maintenance, quality control is not strict, 1, cleaning the shaft neck, oil circuit, oil filter, and replace the clean quality requirements of the lubricating oil2, with the repair after scraping the bush or new bush3, if found wrong installation, should be timely find4, pay attention to maintenance qualityBecause of the unreasonable structure of cavitation bearing (bearing on the oil is not reasonable, the shaft vibration), steam bubble formation of oil film bearing, steam bubble rupture, local surface creates a vacuum caused by small spalling cave erosion damage 1, increase the supply pressure2, improve the shape of the oil groove and groove, modify the edge or shape of the groove to improve the shape of the oil film streamline3, reduce the bearing clearance, reduce axle sway4, change the more suitable bush materialElectric erosion due to insulation is not good or bad ground, or static electricity, a certain voltage is formed between the shaft and bearing, penetrating the oil film between the shaft and bearing the spark, the insulation of the bearing into Pit 1, check the machine, special attention should be paid to some protective devices (such as heat resistance thermocouple wires are well insulated)2. Check the grounding of the machine3, if the damage after electrical erosion is not too serious, you can scrape the bearing4, check the journal, if the shaft on the electric erosion pit, should be polished shaft neck, remove the pit
- Q:Can hydraulic oil be used in motor sliding bearings?
- Do not ask where is the unit where I can, even the fan bearing box reducer is used in hydraulic oil, hydraulic oil because contains anti-wear and lubricating composition, but remember not and mixed with other lubricants
- Q:Are magnetic drive pumps static and sliding bearings a thing?
- 3. radial sliding bearing (1) integral and split division 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..
- 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
