Abstract
The utility model discloses a low impedance bearing, including outer lane, inner circle and be located the outer lane and the inner circle between a plurality of rolling elements and holder, be provided with the electric installation between outer lane and the inner circle. The utility model discloses having added the electric installation on the bearing, having reduced the impedance of bearing greatly, the quick water conservancy diversion of electrostatic energy that the messenger system produced is eliminated.
Description
Technical field
This utility model is related to a kind of Low ESR bearing.
Background technology
Under normal circumstances, in revolution at a high speed, grease can form oil film in Internal and external cycle channel surface to bearing, along with axle
Hold and there is clearance in itself, so the impedance between Internal and external cycle is very big, be almost insulation.Use field in some special bearings
Close, because meeting produces substantial amounts of electrostatic, plain bearing is big due to impedance, poorly conductive is it is impossible to when quick guiding eliminates high-speed rotation
The electrostatic producing, will produce spark when electrostatic puts aside a certain amount of, can affect the stability of system, can draw when serious
Ignition calamity.The purpose of the present invention is to substantially reduce the impedance of bearing, so that electrostatic energy fast guiding is eliminated.
Utility model content
This utility model purpose is to provide a kind of Low ESR bearing for the defect that prior art exists.
This utility model for achieving the above object, adopts the following technical scheme that：A kind of Low ESR bearing, including outer ring, interior
Enclose and be located at some rolling elements between outer ring and inner ring and retainer；It is characterized in that, between described outer ring and inner ring
It is provided with electric installation.
Further, described electric installation is stainless steel spring silk, and its one end is fastened on described outer ring, the other end and card
It is enclosed within described inner ring.
The beneficial effects of the utility model：This utility model adds electric installation on bearing, substantially reduces bearing
Impedance, make system produce electrostatic energy fast guiding eliminate.
Brief description
Fig. 1 is structural representation of the present utility model.
Specific embodiment
Shown in Fig. 1, be related to a kind of Low ESR bearing, including outer ring 1, inner ring 2 and be located between outer ring 1 and inner ring 2
Some rolling elements and retainer 3.Because common axle bearing is in revolution at a high speed, grease can form oil in Internal and external cycle channel surface
Film, along with bearing has clearance in itself, so the impedance between Internal and external cycle is very big, is almost insulation.Therefore, in order to reduce
The impedance of bearing, makes the electrostatic energy fast guiding that system produces eliminate.During design, arrange between described outer ring 1 and inner ring 2
There is electric installation 4.Preferably scheme is that described electric installation 4 is stainless steel spring silk, and its one end is fastened on described outer ring 1,
The other end be fastened on described inner ring 2.
The foregoing is only preferred embodiment of the present utility model, not in order to limit this utility model, all in this practicality
Within new spirit and principle, any modification, equivalent substitution and improvement made etc., should be included in guarantor of the present utility model
Within the scope of shield.
