Electrically Insulated Bearings Profile:
A: What is Electrically Insulated Bearing?
Electrically Insulated Bearing is a general term for the bearings which can stop the electric current through, bearings have the Insulation properties itselves. Its Insulation properties are usually using a special process in the bearing outer or inner ring coated with a layer of insulating material, or the rolling elements made by ceramic materials to guarantee the insulation properties. Electrically Insulated Bearings name and code using the international bearing code. Outer insulation plus VL0241 after bearing type, inner ring insulation bearing type code is VL2071.
B: Using electrically insulated bearings under what circumstances？
Because of the motor in the process of manufacturing even very strictly control the production is difficult to completely avoid the armature and rotor magnetic asymmetry, this asymmetry can produce between the stator voltage, it will produce after bearing current, especially more serious in ac motor, the current in the bearing raceway and rolling body surface corrosion pits, weld mark, electric erosion cut, color, wear and damage. Using the inverter and the technology of frequency conversion motor, of course, also can produce this kind of phenomenon. In order to block this current flows through the bearing, you need to cut off the circuit, so that the insulation bearing and insulation bearing chamber was born.
C: Electric insulation bearing classification.
Now on the market sales of insulation bearing generally there are three: Surface coated ceramic, surface coating resin, using ceramic roller. Surface coated ceramic this amount is the largest.
D: Electric insulation bearing technology parameters
Its size is the same as conventional bearing, assembled interchangeable. Insulation resistance to the measured value is greater than at least 1000Ω when 500 VDC.
E: Electrically insulated bearing applications
Mainly used in high power motor, railway locomotive traction motor, frequency conversion motor, generator, etc
F: Cage of Electrically insulated bearing
According to the different bearing series and size, electrically insulated bearing bracket will be equipped with the following: reinforced nylon 66 cage, stamping steel cage, solid brass cage car system.
G: Advantage of electrically insulated bearing
Electrically insulated bearing can avoid electric corrosion caused by the damage, so compared with the ordinary bearing used in motor can ensure more reliable operation.Compared with other methods of insulation, such as shaft and the shell insulation and so on, more cost-effective and reliable.Insulation bearing dimension and the basic technical characteristics and the insulation bearing the same, so you can absolutely swaps.
