Abstract

Manufacture of stator winding of AC rectifying charging generator for vessel and embedding method, which is characterized in that, obligating a rebound allowance when winding the stator winding through a wire winding mould. When knock the stator winding into shape via the knock-shaped mould, obligating a rebound allowance to make the oblique angle of the stator winding the same as that of the wireembedding time when kicking off the mould. The invention resolves the phenomenon of fixed rotor winding rubs in the end.

Description

A kind of AC rectifying charging generator stator winding is made and embedding method

Technical field

The present invention relates to a kind of mechanism of power generation making method, especially relate to manufacturing of a kind of AC rectifying charging generator stator winding and embedding method.

Background technology

At present, in manufacturing of AC rectifying charging generator stator winding and setting-in process, because internal structure is compact; The space is narrow and small, and specific volume power density is high, and the stator winding end spacing is little; Stator winding end is arranged closely, cause rule after stator winding end have rebound phenomenon, be higher than circle in the stator core when resilience is serious; Cause the rotor winding overhang to be wiped mutually, cause motor windings short circuit, motor normally not to move.

Summary of the invention

The object of the present invention is to provide a kind of manufacturing of AC rectifying charging generator stator winding and embedding method of avoiding the rotor winding overhang to wipe mutually.

Technical scheme of the present invention is: the manufacturing of a kind of AC rectifying charging generator stator winding is during with stator winding coiling moulding, to reserve the resilience surplus through winding former; When striking the shape mould with stator winding knock type, control resilience surplus makes when striking oblique angle that shape moves back stator winding behind the mould with rule consistent.

Said knock type is that stator winding is struck shape, makes that the size and the oblique angle of stator winding end is consistent with stator winding after the rule shaping resilience.

A kind of AC rectifying charging generator stator winding embedding method is in stator coring groove during the setting-in stator winding; Embedding stator winding lower floor in stator coring groove of elder generation; Embedding stator winding middle level and stator winding upper strata again; Then with the mica paper tape half-stack package once, once with the flat bag of glass tape with the end of stator winding; Increase the end hoop, the control stator winding end makes that adjacent lines rod gap is consistent; The stator winding outlet is drawn for this line.

Said increase end hoop is will hold hoop to be fixed on the studdle at stator core two ends with binding strap before the rule; With binding strap stator winding end is fixed on the end hoop again after the winding setting-in is intact; Again stator winding is tied on the end hoop, and at stator winding and one racking seizing band of the inboard increase of headgear.

Said control stator winding end makes that adjacent lines rod gap is consistent, is before also headgear has welded the back dipping lacquer, with re-packing stator winding end is adjusted.

It is the lead-in wire prolongation L with the stator winding upper strata that said stator winding outlet is drawn for this line, does not add lead-in wire in addition.

Springback capacity was reserved in the end when the present invention made through stator winding; Strengthen end banding and shaping in the rule process; At stator core end installation end hoop and with binding strap the stator winding end colligation is being held on the hoop; Stator winding is struck shape, make that the size and the oblique angle of stator winding end is consistent with stator winding after the rule shaping resilience, efficiently solve the rotor winding overhang and wipe phenomenon mutually.

Embodiment

Below in conjunction with accompanying drawing and embodiment the present invention is described further.

Fig. 1, Fig. 2, Fig. 3 are the structural representations of stator winding, comprise studdle 1, end hoop 2 and headgear 3, stator winding upper strata 4, stator winding middle level 5, stator winding lower floor 6, stator core 7, end banding band 8.

During with the coil winding moulding, reserve the resilience surplus through winding former; When striking the shape mould with coil knock type, control resilience surplus makes when striking oblique angle a that shape moves back coil behind the mould with rule consistent.

Said knock type is that coil is struck shape, makes that the size and the oblique angle of winding overhang is consistent with coil after the rule shaping resilience.

Stator winding embedding method: with reference to Fig. 4, Fig. 5, Fig. 6, Fig. 7, Fig. 8; In the groove of stator core 7 during the setting-in stator winding; Embedding stator winding lower floor 6 in the groove of stator core 7 of elder generation; With the end of stator coil with the mica paper tape half-stack package once, wrap once with glass tape is flat then in embedding stator winding middle level 5 and stator winding upper strata 4 again; Increase end hoop 2, the control winding overhang makes that adjacent lines rod gap is consistent; The winding outlet is drawn for this line.

Said increase end hoop 2 is will hold hoop 2 to be fixed on the studdle 1 at stator core 7 two ends with binding strap 8 before the rule; With binding strap 8 winding overhang is fixed on the end hoop 2 again after the winding setting-in is intact; Again coil is tied on end hoop 2, and at coil and one racking seizing band 8 of headgear 3 inboard increases.

Gap through between the THICKNESS CONTROL end winding levels winding that increases coil lashing band 8 is not less than 1.5mm; After also headgear 3 welding finish, before the dipping lacquer, with re-packing end winding is adjusted, made end winding left and right sides adjacent windings neatly even, its gap is not less than 2mm.

The lead-in wire of 12 coils in upper strata is prolonged L=300mm, make 12 lead-out wires reduce by a joint, both reduced the welding job amount, the coil connecting line pad has reduced the damage of welding flame to the winding overhang insulation away from winding overhang simultaneously.
