Problems solved by technology
DC motors require many turning operations during production and maintenance. For medium and large DC motors, the shaft is generally wrapped around the sling and then the crown is used to assist the lifting of the armature. This method requires multiple windings of the sling, and the operation is cumbersome. And occupy the crane station

The invention relates to an armature turning device for a horizontal DC motor. The armature turning device is located at the end of the motor shaft (8). The main parts of the armature turning device include: a straight-handle electric constant torque wrench (1), Barring arm (2), barring arm extension screw (3), barring arm extension screw (4), T-shaped tailstock (5), wrench socket (6) and transition plate (7 ), the transition plate (7) is fixed on the lifting hole (9) on the end face of the motor shaft (8) with bolts (10), and the wrench sleeve (6) is set on the hexagonal bolt head (11) of the transition plate (7), straight The handle electric constant torque wrench (1) is set on the turning arm (2), and the straight handle electric constant torque wrench (1) is inserted into the square hole of the wrench socket (6). The invention is convenient to operate when disassembling and adopting. By changing the position and size of the fixing hole on the long screw rod (4) and the transition plate (7) of different lengths of the turning arm, the armature turning device can be installed on motors with different center heights and rotating shafts with different sizes and diameters. Adoption, high interchangeability.
Description
technical field [0001] The invention relates to an armature barring device for a horizontal DC motor. Background technique [0002] Grinding the arc surface of the brush is a prerequisite for good sliding contact of the DC motor commutation. It is an operation that must be carried out after the DC motor is assembled with a new brush. Grinding traces ensure that the mirror surface of the brush in the sliding contact reaches more than 75% of the cross-sectional area of the brush when the motor is running. For DC motors with different outer diameters of the commutator, the general brush grinding method is to surround the surface of the commutator with sandpaper for grinding, wrap the sling around the motor shaft extension in one direction, and slowly lift the sling with a crane to The moving armature rotates, and the operation is repeated to grind the arc surface of the brush. For DC motors with uneven motor air gaps, it is necessary to fix a point on the surface of the arm...
