Model utility content
In prior art, the transmission speed ratio of wheeled tractor propons taper gear pair is less, be not suitable with the operating environment of China and the technical problem of condition, the purpose of this utility model is to provide a kind of farm tractor front axle taper gear pair, this farm tractor front axle taper gear pair has rational transmission speed ratio, can meet operating environment and the condition of China; Meanwhile, this farm tractor front axle taper gear pair has darker quench hardened case, and premature wear is little, has solved farm tractor front axle taper gear pair short technical problem in working life in prior art; In addition, the tooth top of this farm tractor front axle taper gear pair is done tip relief processing, has solved in prior art taper gear pair contact area out of control, affects the assembling of product and the technical problem of using effect.
To achieve these goals, the utility model has adopted following technological scheme:
A kind of farm tractor front axle taper gear pair, comprises drive bevel gear and the driven wheel of differential being engaged with, and the number of teeth of described drive bevel gear is 11 teeth, and standard pitch diameter is 49.5mm, and addendum coefficient is 0.85, and addendum is 5.436mm, and the face width of tooth is 23.118mm; The number of teeth of described driven wheel of differential is 39 teeth, and standard pitch diameter is 175.5mm, and addendum coefficient is 0.85, addendum 2.214mm, and the face width of tooth is 23mm.
Further, the Fillet radius of described drive bevel gear is 1.6mm, and Tip radius is 0.5mm; The Fillet radius of described driven wheel of differential is 2mm, and Tip radius is 0.5mm.
Further, the flank of tooth carburizing and quenching layer depth of described drive bevel gear and driven wheel of differential is 0.8～1.2mm.
Further, in described drive bevel gear, be wholely set sprocket drive spindle.
Further, described gear shaft is provided with involute outer spline away from one end of drive bevel gear, and the number of teeth of this involute outer spline is 12, and modulus is 2mm, and spline length is 30mm.
Further, the tooth top of described drive bevel gear and driven wheel of differential is done tip relief processing.
The beneficial effects of the utility model are:
Farm tractor front axle taper gear pair of the present utility model, by increasing the standard pitch diameter of drive bevel gear and driven wheel of differential, reach the effect that transverse module increase, the face width of tooth are increased; By changing speed ratio (tooth ratio), increase output torque, to adapt to Chinese farm work requirement; Meanwhile, increase the dark and Working depth of the full-depth tooth of the gear teeth, thereby make transmission more steady to increase overlap coefficient, make contact stress decline simultaneously; In addition, also increase the degree of depth of flank of tooth carburizing and quenching layer, thereby improved the wear resistance of product, reached and extend the product object in working life, reduced noise simultaneously; Farm tractor front axle taper gear pair of the present utility model also done tip relief processing to tooth top, solved that taper gear pair contact area in prior art is out of control, the assembling that affects product and the technical problem of using effect.

Embodiment
Below in conjunction with embodiment of the present utility model is described in further detail.
As shown in Figures 1 to 4, farm tractor front axle taper gear pair of the present utility model, comprise drive bevel gear and the driven wheel of differential being engaged with, the number of teeth of described drive bevel gear is 11 teeth, standard pitch diameter is 49.5mm, addendum coefficient is 0.85, and addendum is 5.436mm, and the face width of tooth is 23.118mm; The number of teeth of described driven wheel of differential is 39 teeth, and standard pitch diameter is 175.5mm, and addendum coefficient is 0.85, addendum 2.214mm, and the face width of tooth is 23mm.
Farm tractor front axle taper gear pair of the present utility model, the Fillet radius of described drive bevel gear is 1.6mm, Tip radius is 0.5mm; The Fillet radius of described driven wheel of differential is 2mm, and Tip radius is 0.5mm.
In the present embodiment, the flank of tooth carburizing and quenching layer depth of described drive bevel gear and driven wheel of differential is 1.2mm.Obviously, in different embodiments, the flank of tooth carburizing and quenching layer depth of drive bevel gear and driven wheel of differential can be other values within the scope of 0.8～1.2mm, can be 0.8mm, 0.9mm, 1.0mm, 1.1mm etc.The flank of tooth carburizing and quenching layer of the farm tractor front axle taper gear pair of the present embodiment is darker, and the flank of tooth can be avoided premature wear, thereby has extended the working life of farm tractor front axle taper gear pair.
