It is low that this scheme provides a processing cost, rational in infrastructure to can improve the driven gear of automobilism stationarity.
Description
Technical field
The utility model relates to a kind of driven gear, belongs to engagement driving part field.
Background technique
Main speed reducer of rear axle is the critical piece reducing rotating speed in automotive transmission, increase moment of torsion.Main speed reducer of rear axle is the direction of transfer realizing slowing down and changing power by one group of helicon gear pair, and helicon gear pair comprises initiatively angular wheel and driven angular wheel, and both are meshed transferring power.Helicon gear pair structure is simple, quality is little, compact dimensions, can realize transmission of power, changes rotating speed, changes the functional objectives such as direction of transfer with less cost.
Application number be 201320477571.5 utility model patent disclose a kind of passive angular wheel of main speed reducer of rear axle, its location end face is tilted to bevel gear direction by the thoughtful inner circumference of cylindrical, after the location end face of passive angular wheel is fixed with flange by the fixed hole of inner ring, excircle end and the flange of location end face fit tightly, improve the stability of passive angular wheel in operation process, and then improve the stationarity of automobilism.But this plane of inclination to processing request will, product reject rate rises, and needs supporting improving flange plate, causes whole product cost to rise.
Model utility content
For the deficiency that prior art exists, it is low, rational in infrastructure that the purpose of this utility model is to provide a kind of processing cost, and can improve the driven gear of automobilism stationarity.
For achieving the above object, the utility model provides following technological scheme: a kind of driven gear, comprise the taper of ring-type, taper upper-end surface is the taper flank of tooth, taper lower end surface is positioning end, taper inner ring is provided with internal spline, internal spline circumference is distributed with positioning hole, taper outer ring bore entirety is shunk towards positioning end by conical tooth, taper outer ring is from top to bottom successively by the first breeze way, second breeze way, horizontal segment is formed, horizontal segment and positioning end outer wall form right angle limit, first breeze way, second breeze way is made up of the curved portions of the line part be obliquely installed and indent respectively, the line part of the first breeze way connects the taper flank of tooth, the curved portions of the first breeze way connects the line part of the second breeze way, the curved portions of the second breeze way connects horizontal segment.
Preferably, line part and curved portions tangent.
Preferably, the curved portions diameter of the first breeze way is identical with the curved portions diameter of the second breeze way, and the angle of inclination in the line part relative level face of the first breeze way is less than the angle of inclination in the line part relative level face of the second breeze way.
Preferably, described taper inner ring top is provided with indent notch, and described positioning hole upper end is molded over pocket bottom, and described pocket side wall and bottom intersection are provided with annular groove.
By adopting technique scheme, the mesh vibration of the taper flank of tooth is carried out multi-buffer by the first breeze way and the second breeze way, and the energy being delivered to positioning end just becomes very little; Taper inner ring adopts spline joint, realizes better dynamic balancing, and arranges the precise match that positioning hole ensures transmission shaft and spline; First breeze way and the second breeze way all adopt straight line and arcuate structure, easy to process, and stress dispersion ability is good simultaneously, ensure parts traveling comfort.
Accompanying drawing explanation
Fig. 1 is the parts drawing of the utility model driven gear;
Fig. 2 is the enlarged view at A place in the utility model Fig. 1;
Fig. 3 is the enlarged view at B place in the utility model Fig. 1.
Accompanying drawing illustrates: 1, the taper flank of tooth; 2, positioning end; 3, internal spline; 4, positioning hole; 5, taper; 6, indent notch; 7, the first breeze way; 8, the second breeze way; 9, horizontal segment; 10, line part; 11, curved portions; 12, annular groove.
Embodiment
A kind of driven gear, comprise the taper 5 of ring-type, taper 5 upper-end surface is the taper flank of tooth 1, taper 5 lower end surface is positioning end 2, taper 5 inner ring is provided with internal spline 3, internal spline 3 circumference is distributed with positioning hole 4, taper 5 outer ring bore entirety is shunk to positioning end 2 by the taper flank of tooth 1, taper 5 outer ring is from top to bottom successively by the first breeze way 7, second breeze way 8, horizontal segment 9 is formed, horizontal segment 9 and positioning end 2 outer wall form right angle limit, first breeze way 7, second breeze way 8 is made up of the curved portions 11 of the line part 10 be obliquely installed and indent respectively, the line part 10 of the first breeze way 7 connects the taper flank of tooth 1, the curved portions 11 of the first breeze way 7 connects the line part 10 of the second breeze way 8, the curved portions 11 of the second breeze way 8 connects horizontal segment 9.The mesh vibration of the taper flank of tooth 1 is carried out multi-buffer by the first breeze way 7 and the second breeze way 8, and the energy being delivered to positioning end 2 just becomes very little; Taper 5 inner ring adopts spline joint, realizes better dynamic balancing, and arranges the precise match that positioning hole 4 ensures transmission shaft and spline; First breeze way 7 and the second breeze way 8 all adopt straight line and arcuate structure, easy to process, and stress dispersion ability is good simultaneously, ensure parts traveling comfort.Line part 10 is tangent with curved portions 11.Tangent structure avoids seamed edge and produces, and smooth transition, Stress transmit is good.
Wherein, curved portions 11 diameter of the first breeze way 7 is identical with curved portions 11 diameter of the second breeze way 8, and the angle of inclination in the line part 10 relative level face of the first breeze way 7 is less than the angle of inclination in the line part 10 relative level face of the second breeze way 8.If line part 10 tilt angle of the first breeze way 7 easily affects too greatly the thickness of the taper flank of tooth 1 above, affect its intensity; And the second breeze way 8 is as main buffer portion, should provide longer cushion stroke, therefore tilt angle should be done a little louder.
Wherein, taper 5 inner ring top is provided with indent notch 6, and positioning hole 4 upper end is molded over pocket bottom, and described pocket side wall and bottom intersection are provided with annular groove 12.Arrange annular groove 12 and can increase relative resilient between the taper flank of tooth 1 and taper 5 outer ring, when the taper flank of tooth 1 stand under load is impacted, reset capability is better.
