Q:When calculating non liquid friction sliding bearings, what is the purpose of checking P, PV, v?
Because for non liquid friction sliding bearings, in order to make the bearing area fully lubricated, sometimes it is better to sacrifice part of the bearing area, and extend the oil tank to or directly into the load area.
Q:Generally speaking, the stiffness of the rolling bearings is more than the stiffness of the sliding bearings - the stiffness of the ball bearings is more than the stiffness of the roller bearings - -
The same size of rolling bearings is lower than plain bearings, and the ball bearings are lower than those of roller bearings.
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:Who says that the sliding bearing motor is better than the ball bearing motor?
The latter is in line contact form, which has large friction force, but also has great carrying capacity, and is suitable for occasions with low speed and heavy load,
Q:How is the axial clearance of plain bearings large?
Adjust the ring gasket by adjusting the outer bolster of the tile.
Q:How to change the sliding bearings of railway freight cars to rolling bearings?
Otherwise, you'll have to change the seat, the axle, the car, the picture, the picture, we can give you some advice
Q:Which sliding bearing materials are free of lubrication?
The sliding bearing material can be lubricated without self-lubricating bearings. It is made of 4 layersA mixture of 1. PTFE and fiber 0.01~0.03mm can form a very good transfer film to protect the grinding shaft, providing the self-lubricating properties of the bearings.2. copper powder layer 0.20~0.35mm, with good bearing capacity and wear resistance, good thermal conductivity, can timely transfer the heat generated during the operation of bearings. The composite can be infiltrated into the gap of copper powder balls, and the bonding strength is improved.
Q:What are the four types of commonly used sliding bearing alloys?
In fact, sliding bearing alloy is not limited to four categories, such as Jiaxing Solid Lubricating Bearing Co. Ltd production of self-lubricating bearing on the use of copper alloy, iron alloy, zinc alloy, Aluminum Alloy, composite materials, engineering plastics and other materials.
Q:How do I move the plain bearings?
The bearing is stationary, the rotor overcomes the resistance of the oil film and rotates in the bearing.
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.
