Description
Technical field
The present invention relates to the injury repair field of motor sliding ring, more particularly to a kind of slip ring without disassembling motor is modified
Processing unit (plant) and its processing method.
Background technique
The beginning of every phase winding is connected on three slip rings made of copper in the three-phase windings of wound-rotor motor, and slip ring is fixed
It is rotated in the shaft of motor with axis.Brush in wound-rotor motor is to make sliding contact with slip ring and formed and be electrically connected
A kind of conductive component.Brush acts on slip ring, as the sliding contact body for importing and exporting electric current.In order to guarantee brush and slip ring
Between continuous contact, have certain pressure between brush and slip ring.
After wound-rotor motor every operating a period of time, due to prolonged sliding friction, slip ring between slip ring and brush
The surface of collector ring can generate the forms such as point, hole shape, it is also possible to have slight burr or non-uniform surface abrasion, at this moment will
Finishing processing is carried out to slip ring.If repaired not in time, the slip ring current collection ring surface of out-of-flatness can aggravate the abrasion of brush,
Simultaneously because brush wear unevenly can it is easy to appear the case where point contact, caused between brush and slip ring arcing etc. extremely put
Electrical phenomena, so that motor be brought integrally to damage.
Therefore it must assure that slip ring surface Glabrous pierces, slip ring concentricity meets the requirements.In the prior art to large and medium-sized
Winding motor is using brush is reprocessed after disassembly wound rotor, and this processing repair mode is cumbersome, slightly not note that also holding
Easily break stator and rotor coil；And it needs entire motor removing processing, time-consuming and laborious, the production and processing period is very
It is long, and assembling deviation can be generated after ressembling, therefore quickly it is very important for online reparation slip ring, if can be not
Finishing processing is carried out to slip ring in the case where disassembly wound rotor, it will be able to which the workload for substantially reducing maintenance personal reduces
The loss of motor bring downtime is dismantled, the utilization rate of motor is improved.
