For the problems referred to above, main purpose of the present invention is to provide a kind of wear resistant automobile semiaxis, strengthens the wear resisting property of automobile axle shaft, reduces becoming flexible between axle side gear and axis body, increases the service life of automobile axle shaft.
For realizing above-mentioned technical purpose, reach above-mentioned technique effect, the present invention is achieved through the following technical solutions:
A kind of wear resistant automobile semiaxis, the axis body and the axle side gear that comprise solid cylindrical, it is characterized in that, described axis body and axle side gear are the wear-resistant steel material, described axle side gear comprises the axis hole that can pass axis body and connect axis body, for with miscellaneous part, meshing continuously teeth groove and the gear teeth that transmit motion and power, the center, both sides of axle side gear is the gear face on plane, described axis hole is provided with the engagement section that can engage with axis body, described axis body is provided with the projection of corresponding engaging, the two ends of the gear teeth are positioned at the gear face place of distance axis bore edges 5-15cm, short " D " font in long two ends in the middle of each gear teeth is.
Use the wear-resistant steel material to make whole automobile axle shaft have in use hardness and resistance to abrasion concurrently, and production technology is easy to grasp.The engagement section engaged with axis body is set on axis hole, well reduce becoming flexible between axle side gear and axis body, the gear teeth are designed to " D " font, increase the frictional area of gear teeth middle part, guarantee the tooth force balance, further increase the service life of automobile axle shaft.
Further, the engagement section of described axis hole semicircle breach that to be several extend to axis hole external diameter direction, be provided with the semi-cylindrical hill of corresponding and engaging with it on axis body, increase the area of contact of axis hole and axis body, reduces loosening between them.
Further, the engagement section of described axis hole trapeze cuts that to be several extend to axis hole external diameter direction, be provided with the trapezoidal projection of corresponding and engaging with it on axis body, increase the area of contact of axis hole and axis body, reduces loosening between them.
Further, the intermediate length of the described gear teeth be two ends length 2-3 doubly.
The invention has the beneficial effects as follows: strengthen the wear resisting property of automobile axle shaft, reduce becoming flexible between axle side gear and axis body, increase the service life of automobile axle shaft.
