Application number is: 200920314958.2 Chinese patent discloses the external twin shaft of a kind of collector ring and has stretched wire wound asynchronous motor; Disclosed technical scheme is in this open file: collector ring is installed between the motor bearings outside and the shaft extension; Fixedly the collector ring seat of brush holder is fixed on the electric machine stand; The rotating shaft center is provided with horizontal deep hole, is provided with six inclined holes that are mutually 60 ° at the inner side of bearing along the shaft circumference direction, is provided with six inclined holes that are mutually 60 ° in the outside of bearing along the shaft circumference direction; The outlet cable of three-phase wound rotor penetrates from preposition inclined hole, links to each other with collector ring after rearmounted inclined hole passes through horizontal deep hole.
Disclosed twin shaft is stretched coiling electric motor and has been solved collector ring existing technical problem of when assembling preferably in the above-mentioned patent; But level of processing deep hole at the rotating shaft center; Process 6 inclined holes at the deep hole two ends respectively and exist processed complex, threading difficult technologies problem; The motor of high-tension winding simultaneously is because the outgoing cable of its rotor winding is thicker, and the employing aforesaid way must be with horizontal deep hole
And the enlarged diameter of inclined hole, causing the rotating shaft boring, this produces considerable restraint for the motor torque size, and motor performance is affected greatly.
Summary of the invention
Stretch the technical problem that high-tension winding rotor lead-out wire exists for solving present twin shaft when being connected with slip-ring device, the present invention provides a kind of twin shaft to stretch the mode of connection of high-tension winding motor axle and rotor winding thereof.
The technical scheme that the present invention adopts is: a kind of twin shaft is stretched high-tension winding motor axle; Comprise a motor shaft body; The two ends of motor shaft are respectively equipped with shaft extension; It is characterized in that: said motor shaft is provided with the slip-ring device erecting bed on the axis body of rotor leading-out wire one side, on the axis body between slip-ring device erecting bed and the rotor leading-out terminal, is separated by 120 ° to be milled with three wire casings that vertically, are parallel to each other, and passes hot jacket one steel bushing on the position of support at motor shaft; Steel bushing and axle interference fit are processed with the Bearing Installation platform on steel bushing.
Wire casing on the described motor shaft, its both sides are provided with the wire clamp fixing threaded hole.
The mode of connection that above-mentioned twin shaft is stretched high-tension winding motor axle rotor winding is: the busbar made from the flat copper bus after the rotor assembling is accomplished is embedded in the wire casing; Busbar outsourcing mica tape insulating barrier tightly wraps with epoxy alkali-free glass silk ribbon then, after busbar passes the groove in the steel bushing; With exposed copper conductor part and cable welding; Cable is connected with slip-ring device, and with the rotor dipping lacquer, epoxy alkali-free glass silk ribbon and busbar are frozen into one.
Above-mentioned busbar is decided screw on axle with wire clamp ledger line clamping,
Beneficial effect of the present invention is: simple in structure, handling ease, busbar is easy for installation, compact, can guarantee the machine shaft torque, gives full play to the performance of motor.
