Preferably, the shaft section comprises a first bearing section, a connecting shaft section and a second bearing section which are arranged from left to right in sequence.

Preferably, the big end module of the bevel pinion shaft structure is 9.3, the tip angle of the bevel gear intersects with the axis of the second bearing section at a point b, the root angle and the partial angle of the bevel gear intersect with the axis of the second bearing section at a point a, and the extension line of the partial angle is perpendicular to the big end face.

Preferably, the outer diameter of the first bearing section is equal to the outer diameter of the second bearing section, the outer diameters of the first bearing section and the second bearing section are slightly larger than the outer diameter of the involute external spline, and a coaxial section is formed among the first bearing section, the second bearing section and the involute external spline.

Has the advantages that:

1. this little bevel gear axle structure adopts the quantity that big end modulus 9.3 designed the awl tooth through this little bevel gear axle structure, and then makes the workable quantity of this structure less number of teeth to this increases its and big bevel gear's drive ratio, improves transmission efficiency.

2. This little bevel gear axle structure is through designing external splines and bearing installation section for the coaxial section that the external diameter is close relatively for this structure adds man-hour, easily processes when can shortening process time, and the bearing can directly be gone on the suit on the shaft part simultaneously, and then is convenient for install and dismantle the bearing.
