Abstract
The utility model discloses a bevel gear pair of a front driving axle for a 160 HP tractor. The bevel gear pair comprises a drive bevel gear and a driven bevel gear. The bevel gear pair is characterized in that the reference diameters of the drive gear and the driven gear are increased to increase the transverse module and the face width of teeth; simultaneously, the whole teeth depth of the gear teeth and the working height of teeth are increased, and the gear ratio is changed to suit field operation; and more stable transmission can be achieved by increasing the overlap coefficient, and the contact stress is lowered. In addition, the depth of a carburized layer of the gear is adjusted to enhance the wear resistance of the product, thereby prolonging the service life of the product and lowering the noise.
Description
Technical field
The utility model relates to the vehicle transmission field of components, particularly a kind of front drive axle cone gear pair that is used for the 160HP tractor.
Background technique
Along with the progress of science and technology and the development of society, farm mechanization obtains further popularizing, the tractor of the big-and-middle horsepower of China almost is import entirely in one's early years, in recent years, maturation along with a collection of domestic manufacturing enterprise, the nationalization level of production of tractor front drive axle obtains bigger raising, has also emerged a collection of new product.
Hypoid cone gear spoke is one of essential parts of tractor, but the gear teeth of existing product calculate the change transverse stress and contact stress is bigger than normal, add the complicated topographical conditions in area, China mountain area, thereby cause the easy premature wear of this kind gear pair, working life is not high, and long-term frequent replacing not only causes bigger inconvenience to the user, has caused bigger economic loss simultaneously yet, in addition, also there is the higher problem of noise in this kind product in application.
The model utility content
In view of this, the utility model provides a kind of front drive axle cone gear pair of the 160HP of being used for tractor, to overcome the deficiency that existing product exists.
The purpose of this utility model provides a kind of front drive axle cone gear pair of the 160HP of being used for tractor, comprises drive bevel gear and driven wheel of differential, and its tooth portion parameter is:
The standard pitch diameter d of described drive bevel gear is φ 63mm, and addendum coefficient is 1.27, and addendum is 8.89mm, and the face width of tooth is 43mm;
The standard pitch diameter D of described driven wheel of differential is φ 259mm, and addendum coefficient is 0.438, addendum 2.66mm, and the face width of tooth is 43mm;
The tooth profile parameter of gear pair is:
Sideshake is 0.18～0.25mm, and Working depth is 11.55mm, and whole depth coefficient is 1.832, and whole depth is 10.7mm, and helix angle is 35 °;
Further, the pressure angle of described driven wheel of differential be 22 ° 30 ';
Further, described tooth profile parameter also comprises:
The tooth ratio is 9: 37, and modulus is 7m;
Described sideshake is 0.18mm;
Further, be provided with carburized case on described drive bevel gear and the driven wheel of differential, described case depth is 0.8～1.3mm.
The beneficial effects of the utility model are:
1. the utility model has increased the standard pitch diameter of master and slave trailing wheel, thereby reach transverse module is increased, the effect that the face width of tooth increases, the full-depth tooth that has increased the gear teeth simultaneously is dark, has increased Working depth, makes transmission more steady by increasing overlap coefficient, contact stress is descended
2. the carburized layer depth of gear is adjusted, thereby improved the wear resistance of product, reached and prolong the product purpose in working life, reduced noise simultaneously.
Other advantages of the present utility model, target, to set forth in the following description to a certain extent with feature, and to a certain extent, based on being conspicuous to those skilled in the art, perhaps can from practice of the present utility model, obtain instruction to investigating hereinafter.Target of the present utility model and other advantages can realize and obtain by following specification and claims.
Description of drawings
In order to make the purpose of this utility model, technological scheme and advantage clearer, below in conjunction with accompanying drawing the utility model is described in further detail, wherein:
Fig. 1 is the structural representation of drive bevel gear,
Fig. 2 is the structural representation of driven wheel of differential,
Fig. 3 be Fig. 2 along A to schematic representation.
Embodiment
Hereinafter with reference to accompanying drawing, preferred embodiment of the present utility model is described in detail.Should be appreciated that preferred embodiment only for the utility model is described, rather than in order to limit protection domain of the present utility model.
As shown in Figure 1, the front drive axle cone gear pair that is used for the 160HP tractor of the present utility model comprises drive bevel gear and driven wheel of differential, and in the present embodiment, its tooth portion parameter is:
The standard pitch diameter d of drive bevel gear is φ 63mm, and addendum coefficient is 1.27, and addendum is 8.89mm, and the face width of tooth is 43mm;
The standard pitch diameter D of driven wheel of differential is φ 259mm, and addendum coefficient is 0.438, addendum 2.66mm, the face width of tooth is 43mm, pressure angle be 22 ° 30 '.
The tooth profile parameter of gear pair is:
Sideshake is 0.18mm, and Working depth is 11.55mm, and whole depth coefficient is 1.832, and whole depth is 10.7mm, and helix angle is 35 °, and the tooth ratio is 9: 37, and modulus is 7m.
For further improving wear resistance, drive bevel gear and driven wheel of differential are provided with carburized case, and case depth is 0.8mm.
For increasing the working life of the gear teeth, the utility model has also adopted stress shot blasting technology that the flank of tooth is handled, and carries out gear lapping, thereby makes the product operation more steady, and noise is lower.
Through testing surface, the domestic steyr automobile drive axle bevel gear stand life test that adopts this product is from 3.1 * 10
5Inferiorly increased by 5.5 * 10
5Inferior, its improvement effect is very significant.
