Abstract
The utility model relates to the motor manufacture technology, and discloses a leading-out wire structure of a motor rotor. The leading-out wire structure of the motor rotor comprises a rotating shaft. The center of the rotating shaft is provided with an axial wire leading hole and wire outlet holes that are communicated with the axial wire leading hole. The leading-out wire structure is characterized in that a cable guiding protection sleeve is sleeved in the axial wire leading hole; the cable guiding protection sleeve is a cylinder equipped with a plurality of uniformly-distributed through holes along an axial direction; and the through holes are communicated with the wire outlet holes. The cable guiding protection sleeve is arranged in the center of a rotor to respectively guide cables of the rotor without intersection of the cables. The leading-out wire structure exhibits a good insulating property, is easy for wire guiding, enables errors to be minimized, and is convenient to repair.
Description
Technical field
The utility model relates to motor manufacturing technology, particularly a kind of rotor leading-out wire structure.
Background technology
Usually, the rotor lead-out wire passes the fairlead of rotating shaft inside, and the wire hole that arranges from rotating shaft is again drawn.This kind lead-out mode installs in the process at multi-cable, easily causes intersection, and the fairlead intersection of wire hole and rotating shaft inside has wedge angle, easily form cable and break, and cable to shake momentum in rotating shaft large, easily cause the accident; When maintenance, also easily cause maintenance difficult because Cable Management is unclear.
Summary of the invention
The purpose of this utility model is to provide a kind of rotor leading-out wire structure, and the cable guide protective sleeve is set in the internal rotor hole, and rotor cable is guided respectively, does not intersect, and good insulating connects easily, reduce fault, and maintenance is convenient.
In order to achieve the above object, the utility model is achieved by the following technical solutions.
A kind of rotor leading-out wire structure; comprise rotating shaft; the wire hole that the center is provided with the axial lead hole and is communicated with described axial lead hole in the rotating shaft; it is characterized in that; described axial lead is set with the cable guide protective sleeve in the hole; described cable guide protective sleeve is for axially being laid with the cylinder of several through holes, and described through hole is communicated with wire hole.
Described wire hole is corresponding one by one with the interior through hole that arranges of cable guide protective sleeve.
Described wire hole internal sleeve is equipped with insulating sleeve.
The inwall in the axial lead hole of the outer wall of described cable guide protective sleeve and rotating shaft closely cooperates.
Rotor leading-out wire structure of the present utility model, comprise rotating shaft, the center is provided with the wire hole of axial lead hole and the connection of described axial lead hole in the rotating shaft, described axial lead is set with the cable guide protective sleeve in the hole, described cable guide protective sleeve is for axially being laid with the cylinder of several through holes, and described through hole is communicated with wire hole; The cable guide protective sleeve guides the rotor inner cable respectively, does not intersect, and good insulating connects easily, reduce fault, and maintenance is convenient.
Description of drawings
Below in conjunction with the drawings and specific embodiments the utility model is described in further detail.
Fig. 1 is the structural representation of a kind of rotor leading-out wire structure of the present utility model, and wherein (a) is the forward cutaway view, (b) is right view;
Fig. 2 is the structural representation of the cable guide protective sleeve of rotor leading-out wire structure among Fig. 1, and wherein (a) is the forward cutaway view, (b) is right view;
Among the figure: 1, cable; 2, insulating sleeve; 3, rotating shaft; 4, cable guide protective sleeve; 5, axial lead hole; 6, wire hole; 7, port; 8, through hole.
Embodiment
With reference to Fig. 1, be a kind of rotor leading-out wire structure of the present utility model, wherein (a) is the forward cutaway view, (b) is right view; With reference to Fig. 2, be the structure of the cable guide protective sleeve of rotor leading-out wire structure among Fig. 1, wherein (a) is the forward cutaway view, (b) is right view.Wherein, the wire hole 6 that rotating shaft 3 interior centers are provided with axial lead hole 5 and are communicated with axial lead hole 5, be set with cable guide protective sleeve 4 in the axial lead hole 5, cable guide protective sleeve 4 is for axially being laid with the cylinder of several through holes 8, and through hole 8 and wire hole 6 are corresponding and be communicated with by port 7 one by one; Wire hole 6 internal sleeve are equipped with insulating sleeve 2, and the inwall in the axial lead hole of the outer wall of cable guide protective sleeve 4 and rotating shaft 3 closely cooperates; The material of insulating sleeve 2 is the epoxy laminate glass bushing, and the material of cable guide protective sleeve 4 is unsaturated polyester (UP).
When connecting the cable 1 of rotor, cable guide protective sleeve 4 guides the cables 1 in the rotating shaft 3 respectively, penetrates respectively in the through hole 8 in the cable guide protective sleeve 4, through port 7, and then passes respectively wire hole 6 outgoing cables 1 corresponding with through hole 8; In this structure, the good insulating of cable 1 and rotating shaft 3 can effectively be protected cable 1, does not intersect in connecting process simultaneously, connects easily, and sign obviously; And at port 7 places, do not have the rotating shaft wedge angle, can effectively protect cable 1 not damaged; In addition, cable 1 is little at the axial lead hole of rotating shaft 35 interior rolling momentum, can effectively reduce fault; This structure also can make motor when breaking down, and overhauls convenient.
Although below by reference to the accompanying drawings embodiment of the present utility model is described, the utility model is not limited to above-mentioned specific embodiments and applications field, and above-mentioned specific embodiments only is schematic, guiding, rather than restrictive.Those of ordinary skill in the art in the situation that does not break away from the scope that the utility model claim protects, can also make a variety of forms under the enlightenment of this specification, these all belong to the row of the utility model protection.
