Description

Armature barring gear for horizontal direct current motor

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. 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.

Disclosure of Invention

The invention aims to design an armature barring gear for a horizontal direct current motor, which avoids occupying large-scale equipment such as a crown block and the like, and can be operated by a single person, is convenient to assemble and disassemble and is simple to operate. The technical scheme of the invention is as follows: an armature barring apparatus for a horizontal direct current motor, the armature barring apparatus being located at an end portion of a rotating shaft (8) of the motor, the armature barring apparatus main body part comprising: the turning mechanism comprises a straight-handle electric fixed torque wrench (1), a turning force arm (2), a turning force arm extension screw pipe (3), a turning force arm extension screw rod (4), a T-shaped tailstock (5), a wrench sleeve (6) and a transition disc (7), wherein the transition disc (7) is fixed on a lifting hole (9) on the end face of a motor rotating shaft (8) by a bolt (10), the wrench sleeve (6) is sleeved on a hexagonal bolt head (11) of the transition disc (7), the straight-handle electric fixed torque wrench (1) is sleeved on the turning force arm (2), the straight-handle electric fixed torque wrench (1) is inserted in a square hole of the wrench sleeve (6), the T-shaped tailstock (5) is arranged in a T-shaped groove (12) of a motor assembly platform, one end of the turning force arm extension screw pipe (3) is in threaded with the turning force arm (2), the other end of the turning force arm extension screw pipe (3) is assembled with the turning force arm extension screw thread of the turning screw rod (4), the end part of the turning moment arm extension screw (4) is connected with a T-shaped tailstock (5).

The working principle of the invention is as follows:

the turning machine is characterized in that a straight-handle electric fixed-torque wrench (1) is started, reaction force is transmitted to a turning force arm (2), the wrench sleeve (6) and a transition disc (7) are driven by the rotation torque of the reaction force, the transition disc (7) is fixed with a motor rotating shaft (8) through a bolt, an armature is driven to rotate, and turning operation is completed.

2 the straight shank electric fixed torque wrench (1) is pressed to turn the gear adjusting button reversely, and the switch can be directly pressed to turn the vehicle in the reverse direction without readjusting the turning force arm (2) and the wrench socket (6).

The invention has the technical effects that:

the invention adopts a hand-held straight-handle electric fixed torque wrench (1) to press a switch to complete the rotation of the armature barring gear of the direct current motor. Transition dish (7) are fixed the fastening through bolt and pivot (8), the barring arm of force (2), the barring arm of force extension solenoid (3), the barring arm of force extension screw rod (4) and T type tailstock (5) are tight through the screw thread, all the other handheld straight shank electronic decide torque wrench (1) can with the barring arm of force (2) and freely plug between spanner sleeve (6), can freely plug between sleeve wrench (6) and transition dish (7), the convenience is operated when dismouting and adoption. The armature barring device can be adopted on motors with different center heights and rotating shafts with different diameters by changing the positions and the sizes of the fixing holes on the barring force arm extension screw (4) and the transition disc (7) with different lengths, and the interchangeability is high.
