Abstract
The invention relates to an inlaid sealing conducting ring. The conducting ring comprises an annular sealing cover, an annular sealing member and an annular conducting piece, the annular sealing cover is inlaid into an oil sealing installation hole in an outer cover of a bearing, and is in interference fit with a contact surface of the oil sealing installation hole. The sealing conducting ring is inlaid into the outer cover of the bearing of a frequency variable motor by being pressed in simply, and the inlaid sealing conducting ring is potable and practical, and integrates sealing with conduction.
Description
Technical field
The present invention relates to the sealing electric installation of motor, particularly to the sealing electric installation of frequency conversion motor.
Background technology
In itself with the presence of oil film, the shaft voltage producing after motor frequency conversion can puncture oil film and cause variable-frequency electric variable frequency motor bearing
Machine bearing galvanic corrosion, leads to motor cannot normally run.Therefore frequency conversion motor needs to be provided with electric installation.
Frequency conversion motor needs to install oil sealing to protect motor bearings, and outer the covering of therefore bearing is typically reserved with oil sealing installation
Hole.The integrated device in prior art organically combining oil sealing with electric installation, needs newly to set mounting hole site on bearing end cover,
Cause using inconvenience.
Content of the invention
The goal of the invention of the present invention is the shortcoming in order to overcome above-mentioned background technology, provides a kind of inserted sealing conductive
Ring.
The technical scheme is that：A kind of inserted sealing conducting ring, include annular seal lid, annular seal and
Annular conductive part, is characterized in that described annular seal lid is inlaid in the seal mounting hole on bearing end cover, annular seal lid
Contact surface interference fit and seal mounting hole between.
The ring-type inner periphery of described annular conductive part and motor shaft interference fit, described annular conductive part is conductive fine
Dimension, the thickness of conductive fiber is 0.5～3mm, and conductive fiber is uniformly bonded in the inner side circle of annular seal lid by conducting resinl
Zhou Shang.
Described annular seal includes locking friction plate and sealing protection part, locking friction plate by sealing protection part with
And conductive fiber is pressed on annular seal lid.
Described sealing protection part is ring-type polytetrafluoroethylene sealing protection part, ring-type polytetrafluoroethylene sealing protection part
Lip forms dynamic radial seal with motor shaft interference fit.
The invention has the beneficial effects as follows：Present configuration has oil sealing and conducting ring dual-use function, global shape and bearing
The seal mounting hole shape covering outward is adapted, and is inlaid in the seal mounting hole on bearing end cover, has easy for installation, adapts to
The wide advantage of property.Present configuration can make the protection that motor reaches IP67 that shaft current can be made to be grounded again；Not only cost-effective but also energy
Bearing service life is made to keep chronicity.
Brief description
Fig. 1 is the profile of present configuration；
Fig. 2 is arranged on the structural representation of bearing end cover for the present invention；
Wherein：1st, annular seal lid, 2, conductive fiber, 3, internal locking piece, 4, sealing protection part, 5, outer locking friction plate, 6,
Motor shaft, 7, bearing end cover, 8, bearing, 9, seal mounting hole.
Specific embodiment
Inserted sealing conducting ring, includes annular seal lid, annular seal and annular conductive as shown in Figures 1 and 2
Part, described annular seal lid（1）It is inlaid into bearing end cover（7）On seal mounting hole（9）Interior, annular seal lid（1）With oil
Seal installation hole（9）Between contact surface interference fit.Between described annular seal lid and seal mounting hole, contact surface is bilateral
The magnitude of interference is 0.05～0.22mm.
Conductive fiber（2）Annular seal lid is uniformly bonded in by conducting resinl（1）Inside circumference on formed ring-type lead
Electric part, conductive fiber（2）Laying depth be 0.5～3mm, conductive fiber and motor shaft（6）Between the magnitude of interference be 2～5mm.
Described annular seal includes outer locking friction plate（5）, sealing protection part（4）And internal locking piece（3）, internal lock
Tight piece（3）By conductive fiber（2）It is pressed on annular seal lid（1）On, outer locking friction plate（5）By sealing protection part（4）Compression
In internal locking piece（3）On.Described sealing protection part（4）For ring-type polytetrafluoroethylene sealing protection part, ring-type polytetrafluoroethylene
The lip of sealing protection part and motor shaft（6）Interference fit forms dynamic radial seal.
In annular seal lid（1）Inside circumference on laying conductive fiber can cause injustice because of the factor of error, therefore logical
Cross internal locking piece（3）Compression can overcome this defect.
The magnitude of interference between the described lip of ring-type polytetrafluoroethylene sealing protection part and motor shaft is 1～3mm.
