Abstract
The utility model discloses a kind of shaft current boundling brush assembly of electric, include conductive fiber beam, and the conductive sleeve of fixed conductive fiber beam, and the area of the cross section of each conductive fiber beam is 1.7~2mm2, resistance≤0.03 Ω of shaft current boundling brush assembly of electric.The utility model has determined the maximum resistance of conductive fiber beam, and cross-sectional area range, it in actual use can a certain number of shaft current boundling brush assembly of electric of reasonable Arrangement, effective control of realization capacitive induction shaft current and radio circuit shaft current on conducting ring according to the voltage and power of motor.
Description
Technical field
The utility model relates to bearings to protect field, in particular to the conducting brush device of bearing.
Background technique
By the motor of frequency conversion drive, shaft current can be all generated.Shaft current includes: capacitive induction shaft current and radio circuit
Shaft current.Through research experiment, the release of capacitive induction shaft current is carried out by minimum resistance, and radio circuit shaft current
Release be by maximum secting area to carry out, and influenced by skin effect.So conductive component both needs to consider conducting surface
Sectional area be also required to consider black box resistance, guarantee conductive component overall electrical resistance be less than motor bearings resistance, protect
The sectional area of conducting surface is demonstrate,proved in the contact area for being greater than bearing and motor shaft.
Summary of the invention
It is a kind of not by high pressure and power limit the purpose of the invention of the present invention is to provide, it can effective control shaft electricity
The boundling brush assembly of electric of stream.
The technical solution of the utility model is: a kind of shaft current boundling brush assembly of electric includes conductive fiber beam, Yi Jigu
Determine the conductive sleeve of conductive fiber beam, the area of the cross section of each conductive fiber beam is 1.7~2mm2, shaft current boundling
The resistance of brush assembly of electric≤0.03 Ω.
The beneficial effects of the utility model are: the maximum resistance and cross-sectional area range of conductive fiber beam has been determined,
In actual use can according to the voltage and power of motor on conducting ring reasonable Arrangement a certain number of shaft current boundlings electricity
Brush assemblies realize effective control of capacitive induction shaft current and radio circuit shaft current.
Detailed description of the invention
FIG. 1 is a schematic structural view of the utility model；
Fig. 2 is that Fig. 1 is mounted on the schematic diagram on conducting ring；
Wherein: 1, conductive fiber beam, 2, conductive sleeve, 3, conducting ring.
Specific embodiment:
A kind of shaft current boundling brush assembly of electric as shown in Figure 1 includes conductive fiber beam (1), and fixed conductive fine
The conductive sleeve (2) of beam is tieed up, the area of the cross section of each conductive fiber beam is 1.7~2mm2, shaft current boundling brush
The resistance of component≤0.03 Ω.
The conductive fiber beam and motor shaft is interference fitted, and magnitude of interference is 0.8~1.2mm.
The conductive sleeve is metal material conductive sleeve, such as copper material conductive sleeve.
It is evenly arranged on conducting ring as shown in Figure 2 just like shaft current boundling brush assembly of electric shown in FIG. 1.
In specific implementation according to the contact area of the ball of bearing or roller and motor shaft, measuring and calculating needs how many a axis electricity
Adfluxion beam brush assembly of electric, as long as guaranteeing the contact surface of all the shaft current boundling brush assembly of electric and motor shaft that are evenly arranged on conducting ring
The sum of product is greater than the ball of bearing or the contact area of roller and motor shaft.
As shown in the table is to match the conducting ring case on roller bearing, reflects boundling brush group on conducting ring
Matching Relationship between part number and roller bearing.
