Description
Technical field
The utility model relates to a kind of flange york, relates in particular to a kind of transmission shaft end face tooth flange york, belongs to the drive technology field.
Background technique
When automobile in motion, transmission shaft is connected with the output terminal of gearbox, the input end of ransaxle through flange york, and passes to ransaxle to the moment of torsion of motor, makes automobile obtain the driving force advance.Transmission shaft is when work; Have around the rotation of its axis high speed with the power assembly and beat what car load Z made progress; The maximum diameter of driving-shaft assembly motion is called swing diameter when the high speed rotating of axis; The size of swing diameter has influence on the layout of transmission shaft on car load, and the transmission shaft of high speed rotating has considerable influence to the smooth-going performance of car load.For reaching these requirements, outside satisfying torque capacity, need the turning radius of transmission shaft little, in light weight etc.The transmission shaft flange york plays crucial effects therein, leans on flange york because transmission shaft centering is main, and the turning radius of flange york is maximum in the driving-shaft assembly, and weight is also very heavy.Use the end tooth flange york structure of transmission shaft that following shortcoming is arranged at present on the automobile: the turning radius of flange york is bigger than normal, and other parts easy and car load are collided when on automobile, moving; Flange york weight is big, causes transmission shaft to be laid particular stress on, and is unfavorable for the dynamic balancing of transmission shaft.
Like Chinese utility model patent notification number: CN2752533Y; Open day: the utility model patent on January 18th, 2006 disclosed a kind of transmission shaft end tooth flange york that is applied in the universal drive shaft two ends; Comprise by universal-joint cross trunnion and transmit the flange york end face that masterpiece is used for end tooth flange york earhole, strap bolt hole; The two earholes outside is set up stiffening rib respectively for the protrusion sphere in the both sides of two ears to flanged surface transition zone, the flange york end face is provided with centroclinal pitch face; This pitch face is the spline-simulating of convex-concave phase embedding, between the center of flange york end face and two ears be recessed arc in empty curved surface.Though alleviate to some extent on this device gross weight, its turning radius is still bigger, influences the layout of car load, the suffered stress of flange york is also bigger, the smoothness when being unfavorable for the transmission shaft high-speed rotation.
Summary of the invention
The purpose of the utility model is still bigger to the turning radius of existing transmission shaft end face tooth flange york; Influence the layout of car load; The defective and the deficiency of the smoothness during the suffered stress considerable influence transmission shaft high-speed rotation of flange york provide a kind of in light weight at present, and working strength is high; The turning radius is little, the less a kind of transmission shaft end face tooth flange york of stress that flange york is suffered.
For realizing above-mentioned purpose; The technical solution of the utility model is: a kind of transmission shaft end face tooth flange york, comprise flange york, and be symmetrically arranged with two transmission shaft earholes on the flange york; Be symmetrically arranged with the end face tooth respectively on four jiaos of the flange york bottom; Toothed area in that the end face tooth links to each other is in twos dug up unnecessary metal formation arc notch, and the outside end face of said two transmission shaft earholes is respectively arranged with the platform that is lower than the flange york outer surface, and the diameter of platform is greater than the diameter of transmission shaft earhole.
Said platform is lower 3 millimeters-8 millimeters than flange york outer surface.
The two ends of said recessed arc curved surface are the plane, and the centre is an arc surface, and plane and arc surface are tangent.
Said transmission shaft earhole axis both sides and between adjacent two end face teeth, offer arc notch.
Also offer bolt hole on the said end face tooth.
The beneficial effect of the utility model is:
1. the outside end face of two transmission shaft earholes of the utility model is respectively arranged with platform, and ream has removed 3 millimeters-8 millimeters metal, makes that the turning radius has obtained reducing, and has optimized the recessed arc curved surface of join domain between the transmission shaft earhole simultaneously, has reduced stress.
2. the utility model is simple in structure; Alleviate the weight of parts, and saved material, helped the spatial arrangement of transmission shaft on car load; Also reduced simultaneously the stress of flange york; Improved transmission shaft dynamic balance performance and working life, the smoothness when helping improving the transmission shaft high-speed rotation can be used on the various Cardan shafts.

Embodiment
Below in conjunction with description of drawings and embodiment the utility model is done further to describe in detail:
Referring to Fig. 3 to Fig. 6; A kind of transmission shaft end face tooth flange york of the utility model comprises flange york 1, is symmetrically arranged with two transmission shaft earholes 2 on the flange york 1; Be symmetrically arranged with end face tooth 5 respectively on four jiaos of flange york 1 bottom; Toothed area in that end face tooth 5 links to each other is in twos dug up unnecessary metal formation arc notch, and the outside end face of said two transmission shaft earholes 2 is respectively arranged with the platform 3 that is lower than flange york 1 outer surface, and the diameter of platform 3 is greater than the diameter of transmission shaft earhole 2.
Said platform 3 is lower 3 millimeters-8 millimeters than flange york 1 outer surface.
The two ends of said recessed arc curved surface 4 are the plane, and the centre is an arc surface, and plane and arc surface are tangent.
Said transmission shaft earhole 2 axis both sides and between adjacent two end face teeth 5, offer arc notch.
Also offer bolt hole 6 on the said end face tooth 5.
Be symmetrically arranged with two transmission shaft earholes 2 on the flange york 1; Universal-joint cross trunnion is through transmission shaft earhole 2 transfer function power; End face is respectively arranged with the platform 3 that is lower than flange york 1 outer surface in the outside of two transmission shaft earholes 2, and the diameter of platform 3 is greater than the diameter of transmission shaft earhole 2.Arc surface ream adding transmission shaft earhole 2 outside end face in man-hour is flat, by ream 3 millimeters-8 millimeters and formed a plane.So not only removed part metals; Alleviated the weight of flange york 1; Be beneficial to the moving balance quality of transmission shaft, prior being is flange york 1 turning radius biggest place here, and this improvement has reduced the turning radius of flange york 1; Make corresponding the reducing of swing diameter of driving-shaft assembly, made things convenient for the spatial arrangement on car load.
Also be symmetrically arranged with end face tooth 5 on four jiaos of flange york 1 bottom, end face tooth 5 is the alternate spline-simulating of convex-concave, on end face tooth 5, also offers bolt hole 6, is used for being connected with power transmission shaft.Dig up unnecessary metal pasting apart from 2 millimeters of profiles of tooth and be located at the toothed area that four end face teeth 5 link to each other in twos; Form arc notch; This breach lays respectively at the both sides of transmission shaft earhole 2 axis, and thickness is identical with the thickness of end face, and forms certain radian to reduce stress.
Referring to Fig. 3; Recessed arc curved surface 4 at join domain between transmission shaft earhole 2 has also passed through optimal design, and it is the plane that original direct arc transition is optimized for two ends, and the centre is an arc surface; And the shape that plane and arc surface are tangent; Not only help the dynamic balancing of transmission shaft, but also reduced the stress of flange york 1, improved working life.
The utility model has reduced gross weight about 1 kilogram, and the turning radius of driving-shaft assembly has reduced 3 millimeters-8 millimeters, and has reduced by 20% stress, can be used on the various Cardan shafts, and using scope is wide.
