Abstract
The utility model discloses a driven conical tooth wheel of rear axle, including annular conical body, characterized by: the conical body up end is the conical tooth face, and the terminal surface is the burnishing surface under the conical body, and the conical body inner circle is equipped with at least concentric buffering punch combination by three -section ladder - like distribution and becomes, and the terminal surface equipartition has the screw hole of mounting flange dish usefulness under the conical body, and conical body outer lane circumference distributes there is at least round dashpot. It is low that this scheme provides a processing cost, rational in infrastructure to can improve the driven conical tooth wheel of rear axle of automobilism stationarity.
Description
Technical field
The utility model relates to the driven angular wheel of a kind of back axle, 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 the driven angular wheel of the back axle that can improve automobilism stationarity.
For achieving the above object, the utility model provides following technological scheme: the driven angular wheel of a kind of back axle, comprise the taper of ring-type, taper upper-end surface is the taper flank of tooth, taper lower end surface is burnishing surface, taper inner ring is provided with and is at least made up of the concentric cushion hole of three sections of stepped distributions, and taper lower end surface is evenly equipped with the tapped hole of fixed flange, and taper outer ring circumference is distributed with at least one circle dashpot.
Preferably, the distance of the described dashpot distance taper flank of tooth is greater than the distance of distance taper lower end surface.
Preferably, the cross section of described dashpot is arc.
Preferably, described cushion hole comprises the first cushion hole, the second cushion hole, the 3rd cushion hole that are distributed successively to taper lower end surface by taper upper-end surface, described first cushion hole cross section is inverted trapezoidal, described second cushion hole and the 3rd cushion hole cross section are all square, and the second cushion hole diameter is greater than the 3rd cushion hole diameter.
Preferably, described taper surface is provided with carburizing and quenching layer.
By adopting technique scheme, in order to reduce the vibration passing of taper upper-end surface engagement generation on the cooperation flange of lower end surface, carry out cooperation damping by arranging multi-buffer at taper inner ring and arranging dashpot in taper outer ring, improve speed reducer traveling comfort.The program only carries out machining at Internal and external cycle, and processing cost is low, rational in infrastructure, and can change on existing product, very convenient.
Accompanying drawing explanation
Fig. 1 is the parts drawing of the utility model angular wheel;
Fig. 2 is the enlarged view at A place in the utility model Fig. 1.
Accompanying drawing illustrates: 1, the taper flank of tooth; 2, burnishing surface; 3, tapped hole; 4, the first cushion hole; 5, the second cushion hole; 6, the 3rd cushion hole; 7, dashpot.
Embodiment
The driven angular wheel of a kind of back axle, comprise the taper of ring-type, taper upper-end surface is the taper flank of tooth 1, taper lower end surface is burnishing surface 2, taper inner ring is provided with and is at least made up of the concentric cushion hole of three sections of stepped distributions, taper lower end surface is evenly equipped with the tapped hole 3 of fixed flange, and taper outer ring circumference is distributed with at least one circle dashpot 7.In order to reduce the vibration passing of taper upper-end surface engagement generation on the cooperation flange of lower end surface, cooperation damping is carried out by arranging multi-buffer at taper inner ring and arranging dashpot 7 in taper outer ring, improve speed reducer traveling comfort, the cushion hole of stepped distribution can ensure that taper lower end surface has larger surface of contact, to ensure that when coordinating with flange plate uniform force everywhere.
Wherein, dashpot 7 is greater than the distance of distance taper lower end surface apart from the distance of the taper flank of tooth 1.Dashpot 7 arranges the bulk strength gone up very much and easily affect the taper flank of tooth 1, and Long-Time Service easily causes the taper flank of tooth 1 to be out of shape.
Wherein, the cross section of dashpot 7 is arc.Arc section is convenient to be processed and has good oil storage capacity, lubricant oil can be thrown out by centrifugal force again, to each component lubrication of whole speed reducer when angular wheel rotates.Cushion hole comprises the first cushion hole 4, second cushion hole 5, the 3rd cushion hole 6 that are distributed successively to taper lower end surface by taper upper-end surface, first cushion hole 4 cross section is inverted trapezoidal, second cushion hole 5 and the 3rd cushion hole 6 cross section are all square, and the second cushion hole 5 diameter is greater than the 3rd cushion hole 6 diameter.Inverted trapezoidal structure can allow the taper flank of tooth 1 of trapezoidal side and inclination adaptive, and taper dynamic balancing is better.Taper surface is provided with carburizing and quenching layer.Infiltration quench hardened case can make taper surface more wear-resisting, and longer service life is of a specified duration.
