Description
Technical field
The utility model relates to a kind of automobile starting motor, especially a kind of stator module of automobile starting motor.
Background technology
The stator module of automobile starting motor comprises that stator casing reaches at the uniform magnet steel that makes progress in stator casing inwall week.At present, magnet steel adopts following two kinds of structures to fix usually:
Bonded structure promptly is coated with on magnet steel and spreads bonding agent, by frock magnet steel is fixed on the corresponding position of stator casing inwall then, toasts the back bonding agent by drying tunnel and solidifies, thereby magnet steel is completely fixed on the stator casing;
Magnetic assist bar structure, i.e. the first magnetic assist bar of respective numbers in the welding of stator casing inwall is determined the position of magnet steel by the position of magnetic assist bar, and then fixes by snap in H type grooved jump ring between magnetic assist bar and magnet steel.The grooved jump ring is stuck in the axial two ends of magnetic assist bar and magnet steel by two openings of H type, forms axial location; Grooved jump ring H type waist both sides are provided with respectively the shell fragment of being close to magnetic assist bar and magnet steel, form circumferentially location, and realize magnet steel and himself is fixing by the tension force of shell fragment
But all there is the shortcoming of complex process in the stator module of above-mentioned two kinds of structures: preceding a kind of structure need be placed on stator module in the drying tunnel and toast; A kind of structure in back need be welded the magnetic assist bar on stator casing.
The utility model content
In order to overcome existing deficiency, technical problem to be solved in the utility model provides the stator module of the simple automobile starting motor of a kind of technology.
The technical scheme that its technical problem that solves the utility model adopts is: the stator module of automobile starting motor, comprise that stator casing reaches the grooved jump ring that is provided with shell fragment in the uniform magnet steel that makes progress in stator casing inwall week, both sides, described grooved jump ring is arranged between the adjacent magnet steel, and described shell fragment is close to adjacent magnet steel respectively; At least one end in the axial two ends of described magnet steel is provided with annular spring, and described annular spring is provided with the elasticity washer of being close to the magnet steel axial end.
Further, all grooved jump ring and annular springs are integration stamped molded.
The beneficial effects of the utility model are: magnet steel is circumferentially located by the grooved jump ring, by the annular spring axial location; The tension force of grooved jump ring shell fragment fixedly also is being fixed on himself between the magnet steel in the magnet steel simultaneously, and the tension force of annular spring dependence self is close to form on the outer casing inner wall and fixes.The stator module of this programme is simple in structure, and technology is simple, stable performance.
Description of drawings
Fig. 1 is a three-dimensional structure schematic diagram of the present utility model;
Fig. 2 is the schematic three dimensional views of stamping forming grooved jump ring of integral type of the present utility model and annular spring.
Embodiment
Below in conjunction with drawings and Examples the utility model is further specified.
As shown in Figure 1 and Figure 2, the stator module of automobile starting motor of the present utility model, comprise that stator casing 1 reaches the grooved jump ring 3 that is provided with shell fragment 31 in the uniform magnet steel 2 that makes progress in 1 inwall week of stator casing, both sides, described grooved jump ring 3 is arranged between the adjacent magnet steel 2, and described shell fragment 31 is close to adjacent magnet steel 2 respectively; At least one end in described magnet steel 2 axial two ends is provided with annular spring 4, and described annular spring 4 is provided with the elasticity washer of being close to magnet steel 2 axial ends 41.
But because the tension force of the shell fragment 31 of grooved jump ring 3 both sides is tilting force, for fear of 3 turnover of grooved jump ring, further, above-mentioned all grooved jump rings 3 be integration stamped molded with annular spring 4, by annular spring semi-finals change fixing of grooved jump ring 3.Certain above-mentioned grooved jump ring 3 and annular spring 4 also can adopt riveted joint, are welded as monolithic construction or are riveted on modes such as stator casing respectively, but it is integration stamped molded in the fixedly while that guarantees grooved jump ring 3, further facilitated operation, guaranteed between the grooved jump ring 3, the positional precision between grooved jump ring 3 and the annular spring 4, thereby guaranteed the positioning accuracy of magnet steel 2, improve the consistency of stator module, and then improved the stability of motor performance.
In order to guarantee the axial location precision of magnet steel 2, prevent that annular spring 4 from endwisely slipping at the tension force effect lower edge of elasticity washer 41 stator casing 1, said stator shell 1 is a stamping parts, described stator casing 1 is provided with stamping forming position limiting structure; Described annular spring 4 is provided with stamping forming and the fixed structure that matches with position limiting structure.Above-mentioned position limiting structure and fixed structure are compared with riveted joint, screw, mode such as bonding, and convenient disassembly is simple to operate.
Concrete, above-mentioned position limiting structure and fixed structure are respectively spacing preiection 11 and fixing hole 42.Compare with structures such as limited step, spacing rings, the structure fabrication of hemispheric spacing preiection 11 and fixing hole 42, install simplyr, and can satisfy location on the axial and circumferential simultaneously.
Concrete, the installation of magnet steel 2 for convenience, above-mentioned magnet steel 2 one ends are provided with annular spring 4; Described grooved jump ring 3 axial ends are the stiff ends 32 that link to each other with annular spring 4, and the other end is a free end 33.During installation, earlier grooved jump ring 3 and annular spring 4 are installed on the stator casing 1, then magnet steel 2 are pushed the assembling that can finish stator module in the adjacent shell fragment 31 of adjacent grooved jump ring 3 and the holddown groove that the elasticity washer 41 on the annular spring 4 between the adjacent shell fragment 31 is formed by the free end 33 of grooved jump ring 3.
In order further to make things convenient for the installation of magnet steel 2, the shell fragment 31 of above-mentioned grooved jump ring 3 free ends 33 both sides is respectively to the 3 center bendings of grooved jump ring, and the adjacent shell fragment 31 by adjacent grooved jump ring 3 constitutes horn mouths and further facilitated pushing of magnet steel 2.
Owing to only be provided with annular spring 4 at magnet steel 2 one ends, in order to prevent endwisely slipping of magnet steel 2, the stator casing 1 of above-mentioned grooved jump ring 3 free ends 33 1 sides be provided with stamping forming and with the contacted limited step 12 of magnet steel 2 axial ends.Therefore, magnet steel 2 axial two ends all are provided with corresponding structure and carry out spacing.Adopting above-mentioned stamping forming limited step 12 is to make for convenience, simplify the operation, and can certainly adopt other modes to replace.
The stator module of this programme is simple in structure, and technology is simple, high conformity, stable performance.
