Abstract
The invention mainly relates to a non-contact type electric energy transmission device, which comprises a distance calibration knob, a rotating shaft fixing ring, an end cover fixing ring, an end ring fixing screw and a nano-material fixing block; the distance calibration knob and the nano-material fixing block are arranged on the rotating shaft fixing ring; furthermore, the distance calibration knob is capable of controlling the distance between the nano-material fixing block and the end cover fixing ring; the end cover fixing ring is fixed on a motor end cover through the end ring fixing screw; and the rotating shaft fixing ring is fixed on a motor shaft. The non-contact type electric energy transmission device disclosed by the invention has the advantages of being simple in structure, convenient to use and capable of effectively prolonging the service life of a bearing.
Description
Technical field
The invention belongs to electric energy transmission field, particularly relates to a kind of non-contact type apparatus for transmitting electric energy.
Background technology
At present, most of method for eliminating shaft current is exactly directly to be grounded on bearing, makes shaft voltage be zero, and then is played
Eliminate bearing voltage and prevent the purpose that bearing film punctures, however, with the method general occasion is can be only applied to, for that
The stricter environment of a little environmental requirements, such as the explosion separation motor in colliery, if rotating shaft is directly grounded, it is possible to produce fire
Flower, has a strong impact on the safety in mining area.Urgently study a kind of contactless power transfer.
The content of the invention
Goal of the invention
In order to overcome the above-mentioned deficiencies of the prior art, the present invention proposes a kind of non-contact type apparatus for transmitting electric energy, and this is non-
The design of contact power transfer can control bearing both end voltage in certain scope, to mitigate because bearing film hits
Wear and caused bearing damage.
Technical scheme
A kind of non-contact type apparatus for transmitting electric energy, it is characterised in that：Including range calibration knob, rotating shaft retainer ring, end cap
Retainer ring, end ring fixed screw and nano material fixed block；Range calibration knob and nano material fixed block are placed in rotating shaft and consolidate
Determine on ring, and range calibration knob can control the distance of nano material fixed block and end cap retainer ring；End cap retainer ring is led to
Cross end ring fixed screw to be fixed on electric motor end cap, rotating shaft retainer ring is fixed on motor shaft.
The nano material fixed block and end cap retainer ring are made by permanent-magnet material.
It is attached by spring between range calibration knob and nano material fixed block, range calibration knob and nanometer material
Material fixed block is the both sides for being arranged in pairs in rotating shaft retainer ring.
Advantage and effect
Advantages of the present invention is as follows with good effect：
Bearing voltage is passed through point discharge by the present invention so as to is reduced to safe range, and then is served protection bearing
Effect.

Specific embodiment：
With reference to the accompanying drawings and detailed description the present invention is described further：
The present invention relates to a kind of non-contact type apparatus for transmitting electric energy, as shown in Figure 1, Figure 2, shown in Fig. 3 and Fig. 4, the device bag
Include range calibration knob 1, rotating shaft retainer ring 2, end cap retainer ring 3, end ring fixed screw 4, nano material fixed block 5；Apart from school
Quasi- knob 1 and nano material fixed block 5 are placed in rotating shaft retainer ring 2, and range calibration knob 1 can control nano material
The distance between fixed block 5 and end cap retainer ring 3, end cap retainer ring 3 is fixed on electric motor end cap by end ring fixed screw 4,
Rotating shaft retainer ring 2 is fixed on motor shaft.
The nano material fixed block 5 and end cap retainer ring 3 are made by permanent-magnet material, are fixed by nano material
Block 5 and end cap retainer ring 3 it is mutually exclusive avoiding making the nanometer on nano material fixed block 5 because of the vibration of motor bearings
The result that material and the contact of end cap retainer ring 3 are damaged.
Be attached by spring between range calibration knob 1 and nano material fixed block 5, range calibration knob 1 with receive
Both rice material fixed blocks 5 are the both sides for being arranged in pairs in rotating shaft retainer ring 2, and the effect of wherein spring is to prevent nano material from consolidating
Determine block 5 to contact with end cap retainer ring 3.
Spring between range calibration knob 1 and nano material fixed block 5 has only served protective effect, that is, works as nanometer
The distance of material fixed block 5 and end cap retainer ring 3 it is little to a certain extent when, due to nano material fixed block 5 and end cap it is solid
The permanent-magnet material determined on ring 3 is mutually exclusive, makes the distance between nano material fixed block 5 and end cap retainer ring 3 be limited in reality
In the range of needs.When super going beyond the scope, spring is inoperative.
The course of work of the present invention is as follows：
End cap retainer ring 3 is fixed on electric motor end cap by end ring fixed screw 4, and rotating shaft retainer ring 2 is fixed on motor shaft
On, range calibration knob 1 and nano material fixed block 5 are fixed in rotating shaft retainer ring 2 and are rotated with rotating shaft, and by distance
The distance between the calibration control nano material of knob 1 fixed block 5 and end cap retainer ring 3, when motor works, the device is just by height
Shaft voltage to a certain extent is fallen power consumption by the point discharge of nano material.
