Description
Technical Field
The invention relates to an armature barring gear for a horizontal direct current motor.
Background
Grinding the arc surface of the electric brush is used as the premise of good commutation sliding contact of the direct current motor, the operation which is required to be carried out after the direct current motor is assembled with a new electric brush is carried out, the electric brush and the contact surface of the electric brush are ground according to the outer arc surface of the commutator, so that four corners of the electric brush are provided with grinding traces, and the condition that the sectional area of the electric brush reaches more than 75% of the sliding contact surface of the electric brush in the sliding contact process when the motor operates is ensured. For direct current motors with different commutator outer diameters, the general brush grinding method is to surround grinding sand paper on the commutator surface, wind the hanging strip around the motor shaft extension in one direction, use the crane to slowly lift the hanging strip to coil the electric pivot to move, and repeat the operation to grind the brush cambered surface. For the direct current motor with uneven motor air gaps, a point needs to be fixed on the outer surface of the armature, and the coiling armature measures the air gaps between the point and each magnetic pole; then, a fixed magnetic pole is found, and the armature is coiled to measure the air gap between the magnetic pole and each point on the outer surface of the armature so as to measure the concentricity of the magnetic pole and the roundness of the outer circle of the armature. The direct current motor needs more processes of jigger operation during production and maintenance, and for medium and large direct current motors, a rotating shaft is generally adopted to wind the hanging strip, and then an overhead traveling crane is adopted to assist in lifting a disc moving armature, so that the hanging strip needs to be wound for many times, the operation is more complicated, and the overhead traveling crane station is occupied.
