Description
Technical Field
The invention relates to the field of damage repair of motor slip rings, in particular to a slip ring finishing device without disassembling a motor and a processing method thereof.
Background
The starting end of each phase winding in the three-phase windings of the wound-rotor motor is connected to three copper slip rings, and the slip rings are fixed on a rotating shaft of the motor to rotate along with the shaft. The brush in a wound-rotor motor is a conductive member that makes sliding contact with a slip ring to form an electrical connection. The brush acts on the slip ring and serves as a sliding contact body for conducting and discharging current. In order to ensure continuous contact between the brush and the slip ring, a certain pressure is applied between the brush and the slip ring.
After the wound-rotor motor is operated for a period of time, the surfaces of slip rings and collector rings of the slip rings generate pockmarks, pits and other forms due to long-time sliding friction between the slip rings and the electric brushes, and slight burrs or uneven surface abrasion are possibly generated, and then the slip rings need to be trimmed. If not in time restoreing, the wearing and tearing of brush can aggravation on the slip ring collecting ring surface of unevenness, because the condition of brush point contact between inhomogeneous can very easily appear in brush wearing and tearing simultaneously causes the abnormal discharge phenomena such as drawing the arc to bring the motor overall damage.
Therefore, the surface of the slip ring is smooth and burr-free, and the coaxiality of the slip ring meets the requirement. In the prior art, the large and medium-sized wound motor is processed with the electric brush after the wound rotor is disassembled, the processing and repairing mode is very troublesome and careless, and the stator and the rotor coil are easy to be damaged; and need to tear down the processing with whole motor, waste time and energy, production cycle is very long, can produce the assembly deviation after reassembling in addition, consequently repair the sliding ring on line fast just seems very important, if can repair the processing to the sliding ring under the condition of not dismantling wound rotor, just can greatly reduced maintenance personal's work load, reduced the breakdown downtime loss that the motor brought of dismantling, improved the rate of utilization of motor.
