Abstract
The utility model relates to a mobile device for direct current motor, the mobile device is located between motor brush device (6) and front end housing (5), the dress is joined in marriage in screw rod (1) one end in first fixed block (2), first fixed block (2) both ends adopt the nut fixed, the dress is joined in marriage at screw rod (1) the other end to staff (4) screw thread, staff (4) clearance fit is in the through -hole of second fixed block (3), the bolt fastening is passed through on front end housing (5) in first fixed block (2), second fixed block (3) are fixed on brush device (6). The utility model discloses a spanner rotates screw rod (1) just gently can make the brush on the brush device move at the surperficial circumferencial direction of direct current motor commutator. First fixed block (2) through bolt and front end housing tight, second fixed block (3) through bolt and brush device tight, a whole is constituteed through screw rod (1) and staff (4) in first fixed block (2), second fixed block (3), plays certain strengthening effect to brush device.
Description
Technical field
The utility model relates to a kind of mobile device for direct current machine.
Background technology
Brushgear is vitals in direct current machine, by being fixed on the sliding contact between brush on brush holder support brushgear and the commutator of rotation, external circuit is connected with armature circuit.Brush should be positioned at the neutral position of motor pole, if depart from magnetic pole neutral point, and rotor field and magnetic pole misalignment angle, resultant magnetic field offsets, will cutting magnetic line by the winding of short circuit, induces electromotive force, form short circuit current, spark will be produced under brush.Whenever direct current machine overhaul, brush carrier position is moved, and all brush must be adjusted to again accurately its neutral position, need shifting brush brush holder position repeatedly, make it on neutral position.Shifting brush brush holder position, conventional method regulates with jack top brushgear, and the method degree of regulation is low, and the inconvenience that operates.
Summary of the invention
The purpose of this utility model designs high, the easy to operate mobile device for shifting brush setting position of a kind of degree of regulation.The technical solution of the utility model is: a kind of mobile device for direct current machine, mobile device is positioned between brush apparatus for motor (6) and front end housing (5), mobile device main element comprises: screw rod (1), first fixed block (2), second fixed block (3), little axle (4), first fixed block (2) is fitted in screw rod (1) one end, first fixed block (2) two ends adopt nut to fix, little axle (4) screw thread is fitted in screw rod (1) other end, little axle (4) matched in clearance is in the through hole of the second fixed block (3), first fixed block (2) is bolted on front end housing (5), second fixed block (3) is fixed on brushgear (6).
Utility model works principle:
1 makes lengthening distance or shortening between the first fixed block (2) and little axle (4) by rotating screw bolt (1), because screw rod (1) external diameter is less than the second fixed block (3) hole internal diameter, as shown in Figure 4, little axle (4) can rotate in the second fixed block (3), thus drive the second fixed block (3) mobile, as shown in Figure 5, drive brushgear (6) clockwise or rotate counterclockwise.
2 first fixed blocks (2) by bolt and front end housing tight, second fixed block (3) by bolt and brushgear tight, first fixed block (2), the second fixed block (3) are formed a whole by screw rod (1) and little axle (4), play certain reinforcement effect to brushgear.
The utility model employing spanner gently rotating screw bolt (1) just can make the brush on brushgear move in DC motor commutator surface perimeter direction.First fixed block (2) by bolt and front end housing tight, second fixed block (3) by bolt and brushgear tight, first fixed block (2), the second fixed block (3) are formed a whole by screw rod (1) and little axle (4), play certain reinforcement effect to brushgear.
