Abstract
The utility model discloses a front drive axle bevel gear pair for a 50HP tractor, comprising a driving bevel gear and a driven bevel gear, wherein the reference diameter d of the driving bevel gear is phi 58.85mm, an addendum coefficient is 1.2, the addendum is 6.45mm, and the gear surface width is 33mm; the reference diameter D of the driven bevel gear is phi 171.2mm, an addendum coefficient is 0.49, the addendum is 2.63mm and the gear surface width is 27mm. The utility model has the effects of increasing an end module, the gear surface width, the full tooth depth of the gears and the working tooth height of the gears by increasing the reference diameters of the driving bevel gear and the driven bevel gear, is adaptive to China field operation by changing the speed ratio (gear ratio), ensures smooth transmission and lowers the contact stress by increasing an overlap coefficient, and additionally regulates the carburized layer depths of the gears, thereby enhancing the wear resistance of a product, reaching the purpose of 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 50HP 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 pair 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, long-term frequent replacing not only causes bigger inconvenience to the user, has also caused bigger economic loss simultaneously; 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 50HP 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 50HP 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 58.85mm; Addendum coefficient is 1.2; Addendum is 6.45mm; The face width of tooth is 33mm;
The standard pitch diameter D of described driven wheel of differential is φ 171.2mm; Addendum coefficient is 0.49; Addendum 2.63mm; The face width of tooth is 27mm;
The tooth profile parameter of described gear pair is:
Sideshake 0.15～0.23mm; Working depth is 9.07mm; Whole depth coefficient 1.882; Whole depth 10.7mm; Helix angle be 36 ° 34 ';
Further, the pressure angle of described driven wheel of differential is 20 °;
Further, described tooth profile parameter also comprises:
The tooth ratio is 11: 32; Modulus is 5.35m;
Described sideshake is 0.15mm;
Further, be provided with carburized case on described drive bevel gear and the driven wheel of differential, described case depth is 0.8～1.2mm.
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, and the full-depth tooth that has increased the gear teeth simultaneously is dark, has increased Working depth; Change speed ratio (tooth ratio), adapt to Chinese farm work more; Make 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.
