Description

Starting machine

The utility model belongs to a kind of starting arrangement of internal-combustion engine, particularly a kind of electric starting device.

Needs for structure, discharge capacity, purposes and the Environmental Conditions condition etc. that satisfy dissimilar internal-combustion engines, guarantee in regulation reliably starting in the starting time, require the starter motor volume less, starting rapidly, and is easy to operate, for example, the 321 type starter motors that present state intrinsic motivation all adopts, its power is less, and physical dimension is bigger, the consumption material is many, and performance can not adapt to the needs of new work engine.

The purpose of this utility model provides a kind of improved novel starter motor, makes its volume-diminished, and material saving improves Performance And Reliability, reduces cost.

Main design of the present utility model is, improve the structure of armature and one-way element, staor winding is crouched into end cap, shortened one-way element simultaneously, the length of armature commutator and iron core has shortened 42.5～49.5 millimeters with armature axial length, makes starter motor general structure size, volume-diminished, weight saving, material saving.In addition the Electromagnetic Design scheme of starter motor is optimized, the complete machine performance is improved, and improved the welding of back panel wiring, improved the overload capacity of starter motor, improve cold performance of automobile and operational safety, thereby reduced cost, obtained obvious economic benefit.

Describe embodiment in detail below in conjunction with accompanying drawing:

Fig. 1 is the structure cut-away view of novel starter motor

Among the figure: (1) is stator, and (2) are armature, and (3) are end cap, and (4) are one-way element, and (5) are transmission fork, and (6) are magnetic switch, and (7) are brush cover.The winding of this novel starter motor stator (1) crouches and has shortened the length of one-way element (4) and armature (2) commutator and iron core into end cap (3) simultaneously, make armature axial length shorten 42.5～49.5 millimeters, thereby armature axial length is 258.5～265.5 millimeters reduces axle amount of deflection when work of armature (2), make full use of the magnetic field winding space, reduced the starter motor housing diameter, machine volume is dwindled.Armature (2) adopts semi-open slot, reduces Carter's coefficient, and uses the epoxy resin sealing, fishing line when avoiding work.Optimized the Electromagnetic Design scheme of starter motor, 65 millimeters of armature (2) intended diameter φ, folded thick 65 millimeters, the armature winding lead is selected 1.6 * 4.5(millimeter for use) flat type copper wire, 29 grooves, the single turn ripple around, the commutator diameter is 35 millimeters of φ, and the staor winding lead is 1.6 * 4.5(millimeter) flat type copper wire, the every utmost point 6 circles, four utmost points two and two strings, the brush sectional dimension is 8 * 16(millimeter) wire gauge is reduced, armature axial length shortens 42.5 millimeters, and one-way element (4) adopts alien planet type cold hobbing structure, magnetic switch (6) adopts the embossing contact, and brush cover (7) adopts totally enclosed type.The back panel wiring welding of novel starter motor adopts middle temperature brazing to replace soldering, has improved overload capacity, complete machine performance and the operational safety of starter motor, has improved the automobile cold start performance.The needs that be to adapt to motor, it is 65 millimeters of φ that novel starter motor (short type) armature (2) is designed to diameter, folded thick 58 millimeters, the armature winding lead is 2.8 millimeters round copper enameled cables of φ, 19 grooves, two circle ripples are around, 35 millimeters of commutator diameter phi.

Novel starter motor can be used for improving performance on many light-duty vehicles that 4920 Engine Series are housed, and reduces cost 10%, with the existing 312 type starter motor performances of using relatively as tabular:
