- Q: Can self lubrication plain bearings bear both axial and radial loads?
- Bearing type is different, the load is not the same. Self lubrication bearings, in fact, are the same as plain sliding bearings, but are designed to lubricate themselves, so they can bear axial and radial loads. General bearings can withstand two-way load, but just to accept the size is not the same. Hope to help you.
- Q: What are the automotive engine journal bearings?
- Also called white alloy Babbitt, tin based white metal used to reduce friction, but low fatigue strength, heat resistance, temperature exceeding 100 DEG C hardness and strength decreased significantly, the gasoline engine used to load. The outstanding advantages of copper lead alloy are its large carrying capacity, high fatigue resistance and good heat resistance. But the running in performance and corrosion resistance are poor. In order to improve its running in and corrosion resistance, a layer of soft metal is usually electroplated on the surface of copper lead alloy into three layers of structural bearings, which are mostly used in high strength diesel engines. Al based alloys include aluminum, antimony magnesium alloy, low tin aluminum alloy and high tin aluminum alloy. High tin aluminum alloy bearings containing more than 20% of tin are widely used in gasoline engines and diesel engines because of their better bearing capacity, fatigue resistance and antifriction performance. The soft coating refers to electroplated a tin or tin lead alloy on the antifriction alloy layer. Its main function is to improve the running in performance of the Bush and to be used as the protective layer of the antifriction alloy layer. When the Bush is in the free state, the distance between the outer ends of the two joint surfaces is larger than the diameter of the bearing bore, and the difference is called the opening of the bearing bush.
- Q: What is the axial series momentum of plain bearings?
- For the rolling bearings and plain bearings of motors, the vibration limits and the measuring methods, please give me the axial distance The inner and outer rings and rolling bodies of rolling bearings should have higher hardness and contact fatigue strength, good wear resistance and impact toughness. General use of special bearing steel manufacturing, commonly used materials are GCrl5, GCrl5SiMn, GCr6, GCr9, etc., after heat treatment, hardness up to 60-65HRC.
- Q: Advantages and disadvantages of plain bearings relative to rolling bearings
- Journal bearings are compared with rolling bearingsAdvantages of plain bearings:1, large friction coefficient, power consumption.2, not suitable for mass production, interchangeability is not good, not easy to install, disassemble and repair.3, the internal gap is large, processing accuracy is not high.4 、 low transmission efficiency, large heat consumption, inconvenient lubrication and maintenance, consumption of lubricant.5, the load, speed and work temperature range is narrow, a small change in the working conditions, the performance of bearings greater impact.6, can not bear radial and axial load simultaneously.
- Q: What are the advantages and disadvantages of rolling bearings?
- Advantages of rolling bearings1, the structure and working principle of rolling bearings to ensure its low coefficient of friction, the friction force is small, has good mechanical efficiency, can keep low power consumption in the operation process of mechanical equipment, and good starting performance.2, rolling bearings have very good accuracy and speed, can meet the operation requirements of a variety of machinery and equipment. Rolling bearings in the operation of the equipment by small friction, low wear and tear, so long service life. There are some products in rolling bearings, which can realize automatic adjustment of the heart, and more widely meet the needs of industrial production.
- Q: Sliding bearings, according to their friction state, why bearings and what bearings?
- 2. boundary frictionThe boundary of oil film thickness is less than 1 microns to two metal surface is completely separated from each other, when the movement of two metal surfaces, metal surface asperities will still considerable rubbing cut, this friction is called boundary friction. The friction law of boundary friction, basically the same with the dry friction, but the friction coefficient decreases, f = 0.1 ~ 0.3. boundary friction though not completely avoid the metal surface wear, but can greatly reduce wear.
- Q: lead and antimony, because of its good wear resistance, high plasticity, good running performance. What is meant by running fit here? Thank you!
- Refers to the ability to work with the spindle neck to adapt to the working environment, especially after the new model or operation has just started. After the running in period, the plain bearing and the shaft neck do not change together.
- Q: Hello, about the bearing problem. Sliding bearings are made of powder metallurgy. What kind of grease does it use?
- You say is the ultra high temperature lubricating powder, and thread anti card grease, the grease types include the following:The total synthesis of anti - thread copper card containing metal powder, grease, commonly known as golden oil, thread, assembly and seal for high temperature.The total synthesis of high temperature anti - white fat card, the connotation of non metal powder. Mainly used for high temperature lubrication, demoulding, assembly, sealing.Total synthesis - black thread sealing grease containing MoS2 powder for bolt thread, casing, drill pipe etc..At present, the product, the tiger head, hotolube and Kluber series of more complete, stable quality. The metallurgical powder you are talking about may be the first or the third. Please choose according to the use.
- Q: Thrust bearing principle
- There seems to be no principle here. The spindle is thrust head and mirror plate, bearing on head and thrust, the thrust oil tank on the head of the lubricating oil base into tile gap cooling.
- Q: What are the lubrication methods of plain bearings?
- The material is divided into lubricating oil lubrication, solid lubricating grease and Jiaxing Solid Lubricating Bearing Co. Ltd production of self lubricating sliding bearing; the oil supply is continuous oil supply and intermittent supply, intermittent supply by pot filling and brought through the needle valve cup oil grease with only intermittent supply. Continuous oil supply can be divided into oil for oil and oil ring core dam, oil pressure.
