There is rotational, have HRB bearing (
)
Jiaxing bearing group sales co. , LTD. (
The company)
Is bearing group co. , LTD. Established in jiaxing spot sales window, specializing in HRB brand bearings, facing the whole country, the existing stock 50 million yuan, covers the whole bearing, have very strong spot supply, is the group's retail sales center.
A, the purpose of the electric insulation bearing the so-called electric insulation bearing is insulation bearing, electric insulation bearing including all can prevent the current through the rolling bearing, both inner ring and outer ring bearing are called insulation bearing with ceramic coating.
Ceramic coating can prevent current through, with insulation ability.
Hybrid bearings made from ceramic roller, therefore also has the insulating ability.
It is by the rolling body to prevent electric current passes through.
Second, the choice of the bearing insulation methods in general, completely eliminate bearing internal potential difference is very difficult.
However, if we can prevent or greatly reduced through the current bearing, can prevent the corrosion of the bearings.
At present all kinds of insulation bearing are designed for this purpose.
According to different types of generating voltage, to select bearing insulation way.
1, along the shaft of the induced voltage along the shaft of the induced voltage will produce after bearing 1 at the same time, the bearing and the bearing 2 current loop.
One reason for this kind of shaft voltage generated is due to the uneven distribution of motor internal magnetic flux, especially in some very logarithm less motor.
At this point, as long as the insulation end bearing can be completely cut off the current loop.
Usually the drive end bearing insulation.
2, the voltage between shaft and bearing seat, if the voltage between the shaft and bearing current through each bearing will be in the same direction.
This is mainly used for frequency converter caused by common-mode voltage.
In this case, the motor at the ends of the bearing should be insulated.
Choose time characteristic of the determinants of the insulation is current voltage.
If it is a dc voltage or low frequency ac voltage, insulation effect depends on the insulation layer of pure resistance;
If it is the high frequency ac voltage (
The common use of frequency converter device)
, depending on the capacitive reactance value of the insulating layer.
