Abstract
The utility model relates to a generator rotor leading-out wire shaft internal fixation device, comprising two wire-passing blocks arranged at two end parts in the centre hole of a rotor shaft, a central rod for fixedly connected with the two wire-passing blocks, and wire pressing rods fixed between the two wire-passing blocks along the axis direction. The number of the wire-pressing rods corresponds to that of the leading-out wires, the wire-pressing rods and the leading-out wires are sequentially distributed in a interleaving mode, the axis outer surfaces of the wire-pressing rods are contacted with the two adjacent leading-out wires and the inner surface of the centre hole. The utility model solves the technical problem that the existing generator rotor leading-out wire fixation device can not fix the leading-out wires between two wire-passing blocks, and the utility model has the advantages of good fixation effect, simple manufacturing technique and light weight.
Description
Technical field
The utility model relates to a kind of generator amature leading-out wire fixture mechanism.
Background technology
A plurality of lead-out wires of generator amature need extract from rotor rotated, prior art all is inwardly to make a call to a centre bore vertically at center, armature spindle one end, between the bottom of centre bore and armature spindle outer surface, beat several cable-through holes, lead-out wire is introduced from cable-through hole in the centre bore in the armature spindle, draw from rotor shaft extension end again, be connected with outside by conducting ring.In the centre bore of armature spindle, for fixing lead-out wire, generally be to be provided with one respectively to cross the line piece at the two ends of centre bore, cross the line piece by the center bar location that is connected for two, rotor axial has a plurality of through holes in mistake line piece upper edge, and rotor leading-out wire just passes from through hole separately respectively.But, because the length of centre bore is oversize, in fact lead-out wire is in vacant state two parts of crossing between the line piece, when rotor high-speed rotates, each lead-out wire is just crossed between the line piece at two and is rocked even twine, except reducing the reliability of lead-out wire work, also may influence the dynamic balancing of rotor.
Summary of the invention
The utility model proposes a kind of generator amature and draw the bobbin inner fixing device, it has solved the technical problem that existing generator amature leading-out wire fixture mechanism can't be fixed two lead-out wires of crossing between the line piece.
Technical solution of the present utility model is:
A kind of generator amature is drawn the bobbin inner fixing device, comprise be arranged on both ends in the armature spindle centre bore cross the line piece, two center bars of crossing the line pieces are used to be connected, its special character is, it also comprises and is fixed on two line ball rods of crossing between the line piece vertically, the quantity of described line ball rod is corresponding with the quantity of lead-out wire, described line ball rod and lead-out wire along the circumferential direction are interspersed successively, and the axial external surface while of described line ball rod contacts with adjacent two lead-out wires and centre bore inner surface.
Above-mentioned line ball rod is a hollow-core construction.
Above-mentioned line ball rod is cylindrical-shaped structure or polygon column structure.
The circumferential surface of above-mentioned line ball rod is provided with a plurality of location notchs that limit the lead-out wire activity vertically.
Above-mentioned two mistake line pieces are fixed the line ball rod by the effect that is connected of center bar.
Above-mentioned two mistake line pieces are fixed the line ball rod by the effect that is connected of center bar.
The utility model has the advantages that:
1, good fixing effect.The utility model is limited in the lead-out wire strictness in the small space that two line balls rod and centre bore inner surface surrounded by the line ball rod, and the surface of line ball rod also can be provided with location notch and is used for fixing more accurately.
2, manufacturing process is simple.The utility model only need be crossed at two and place the line ball rod consistent with lead-out wire quantity between the line piece, and line ball rod and lead-out wire are spaced from each other placement, cross the line piece with center bar with two then and strain in opposite directions, until crossing the line piece line ball rod are fixed.In addition, the structure of line ball rod and processing are also very simple.
3, in light weight.Though the utility model has increased the line ball rod in armature spindle, the line ball rod has adopted hollow structure, has alleviated weight when guaranteeing fixed effect as far as possible.
Description of drawings
Fig. 1 is a structural representation of the present utility model;
Fig. 2 is the A-A cutaway view of Fig. 1;
Fig. 3 is the cross-sectional structure schematic diagram of line ball rod;
Wherein: 1-armature spindle, 2-are crossed the line piece, 3-lead-out wire, 4-center bar, 5-cable-through hole, 6-line ball rod, 7-centre bore, 8-location notch.
Embodiment
The utility model generator amature is drawn the bobbin inner fixing device, comprise crossing line piece 2, being used to be connected two and crossing the center bar 4 of line piece 2, be provided with and be fixed on two line ball rods of crossing between the line piece 26 vertically of both ends in the centre bore 7 that is arranged on armature spindle 1, the quantity of line ball rod 6 is consistent with the quantity of lead-out wire 3 and along the circumferential direction be interspersed successively, makes the axial external surface of line ball rod 6 contact with adjacent two lead-out wires 3 and centre bore 7 inner surfaces simultaneously; The structure of line ball rod 6 is cylindrical-shaped structure or polygon column structure, fixed effect with the polygon column is good, position for better restriction lead-out wire, the circumferential surface of line ball rod 6 also can be provided with the location notch 8 consistent with lead-out wire 3 quantity vertically, location notch 8 can be arranged to the half slot structure, is used to limit the relative position of lead-out wire 3.The axial external surface of line ball rod contacts with adjacent two lead-out wires and centre bore inner surface simultaneously.In order to alleviate the weight of fixture, the line ball rod can be designed to hollow-core construction.After placing the line ball rod, to two tension effects of crossing the line pieces, two inner side ends of crossing the line pieces are compressed two end face axial of institute's live conductor rod, be fixed by center bar; Also can adopt other mechanical means that the line ball rod is fixing.
