Description
Technical field
The present invention relates to a kind of one-way element assembly, be used for automobile starter.
Background technique
The one-way element assembly is the critical component of automobile starter; Its effect be to transmit reliably in the starting process bent axle that moment of torsion that starter motor sends gives motor and motor started its single effect protection starter armature of back mat not reason surmount and cause at a high speed and damage, so fine or not life-span that directly influences automobile of one-way element assembly.
Existing one-way element assembly generally is made up of geared parts, collar, oil sealing trim ring, star wheel, roller, case etc.; Oil sealing trim ring and geared parts cause serious wearing and tearing for to contact firmly in the work, make both spaces can be increasing; Produce oil leakage, have a strong impact on service property (quality); Star wheel and geared parts surface of contact are easy to generate play, cause to produce the gap between the two and directly leakage of oil, have a strong impact on service property (quality); Existing technology lining material adopts common copper sheathing in addition, does not do any processing, causes working life too short, and existing one-way element can not satisfy long-life demand at 3.5 ten thousand times general working life.
Summary of the invention
To the objective of the invention is in order addressing the above problem, a kind of grease-proof seepage to be provided, to improve lining wear resistance, HQ high quality, the one-way element assembly of long lifetime (working life is more than 200,000 times).
In order to achieve the above object; The technological means that the present invention adopts is: a kind of one-way element assembly comprises: geared parts, collar, oil sealing trim ring, star wheel, roller, flat spring, case, and said geared parts comprises gear and lining; On the said gear inwall lining is installed; Said lining is selected the high-strength wearable material for use, in sleeve inner surface the rhombus pit is set, to be installed in the rhombus pit with the shape graphite block; Said oil sealing trim ring material is selected soft material wear-resisting and that sealing is strong for use; Said roller and flat spring are respectively charged in the star wheel curve-surface cavity and inject the moderate lubrication grease; Said oil sealing trim ring is layered on above the star wheel; Said geared parts slides in the star wheel die cavity through the roller face; At geared parts and star wheel surface of contact one corresponding concaveconvex structure is set, makes it drive fit; Said collar is packed in the gear grooved, and said case is enclosed within above the collar and packs tightly star wheel, makes collar, oil sealing trim ring, star wheel keep static loosening.
Geared parts and the concaveconvex structure of star wheel are original planarea and contact and change present step surface contact into.Because during one-way element work; Play can take place, between geared parts and the star wheel under the influence of play its surface of contact the space can appear, planarea contact structures originally; Oil in the star wheel curve-surface cavity directly leaks from the space at an easy rate; Oil leakage has reduced the service time of the oil in the star wheel curve-surface cavity than comparatively fast, thus the working life of having reduced whole one-way element assembly; Make the step surface contact structures into; After the space occurring; Oil could leaking out through landscape surface after through vertical plane under the self gravitation effect, is to move ahead under the Driving force effect at the oil on the vertical plane at the oil on the landscape surface owing to having lost oily action of gravity, owing to Driving force is limited earlier again; Oil leakage on the landscape surface speed of going out can be slow a lot, thereby prolonged working life.
The invention has the beneficial effects as follows: oil sealing trim ring material is selected soft material wear-resisting and that sealing is strong for use; Sealing effect is better; Reduced oily volatilization, prolonged the service time of oil in the oil pocket, reduced geared parts simultaneously and reduced loss with hard contact of oil sealing trim ring; Improve service property (quality), prolonged working life; Geared parts and star wheel surface of contact are provided with a corresponding convex-concave structure, make it drive fit, reduce the leakage and the volatilization of oil in the oil pocket, prolong the service time of oil in the oil pocket, have increased working life when having improved service property (quality); The lining of high-strength wearable material and the rhombus pit is set at internal surface, and fill graphite, improved the rub proofness of geared parts, prolonged working life.
Description of drawings
Below in conjunction with accompanying drawing and embodiment the present invention is further specified.
Fig. 1 is plan view of the present invention (broken section);
Fig. 2 is a left view of the present invention.
Be labeled as among the figure: 1, geared parts, 11, gear, 12, lining, 2, collar, 3, the oil sealing trim ring, 4, case, 5, star wheel, 6, roller, 7, flat spring, 8, Z-shaped back-up ring, 9, jump ring, 10, convex-concave structure.
Embodiment
Like Fig. 1, shown in Figure 2; A kind of one-way element assembly comprises: geared parts 1, collar 2, oil sealing trim ring 3, star wheel 5, roller 6, flat spring 7, case 4, said geared parts 1 comprise gear 11 and lining 12; On said gear 11 inwalls lining 12 is installed; Said lining 12 is selected high-strength wearable material tin bronze for use, and preferred model: QSn6.5-0.1 is provided with equally distributed rhombus pit at lining 12 internal surfaces in this example; Be installed in the rhombus pit with graphite block, improve the rub resistance ability with graphite block with shape; Said oil sealing trim ring 3 materials are selected rubber material wear-resisting and that sealing is strong for use; Said roller 6 is respectively charged in star wheel 5 curve-surface cavities with flat spring 7 and injects the moderate lubrication grease; Said oil sealing trim ring 3 is layered on above the star wheel 5; Said geared parts 1 slides in star wheel 5 die cavities through roller 6 faces; At geared parts 1 and star wheel 5 surface of contact one corresponding concaveconvex structure 10 is set, makes it drive fit; Said collar 2 is packed in gear 11 grooves; Said case 4 is enclosed within above the collar 2 and packs tightly star wheel 5; Make collar 2, oil sealing trim ring 3, star wheel 5 keep static not loosening, dress Z type back-up ring 8 is on star wheel 5 tail ends, and the spring 9 that is installed is contained in the star wheel 5 tail end grooves does not allow Z type back-up ring 8 to get loose.
Can accomplish the one-way element assembly of made of the present invention according to above installation; On the basis that does not change traditional profile, improve the lining wear resistance, reduced the possibility of leakage of oil; Improved service property (quality), brought up to of the present invention product 20 ten thousand time or more by original 3.5 ten thousand times working life.
