When the gear teeth are subject to external force to extrude, can there is phenomenon of rupture generation with the junction of wheel shaft in multiple gear teeth, and bulk strength is poor, so as to
Have impact on the service life of axle shaft gear；If the junction of the first side wall and second sidewall is cambered surface, the first inclined-plane and the
Angle formed by the wall of side is that 135 degree and the second inclined-plane are less than under 135 degree of cooperations with angle formed by second sidewall, is using process
In, multiple gear teeth be subject to external force extrude when, multiple gear teeth can with the junction of wheel shaft occur phenomenon of rupture generation, bulk strength compared with
Difference, so as to have impact on the service life of axle shaft gear；So the first side wall and the junction of second sidewall are cambered surface, first oblique
Face and angle formed by the first side wall be 135 degree and the second inclined-plane with angle formed by second sidewall be under 135 degree of cooperations it is relatively reasonable,
In use, when multiple gear teeth are subject to external force to extrude, will not there is fracture with the junction of wheel shaft or deform in multiple gear teeth
Phenomenon occurs, and bulk strength is stronger, so as to ensure that the service life of axle shaft gear.Circumferentially it is placed equidistant in the inwall of wheel shaft
There are multiple installations raised, constitute between each adjacent installation projection and groove is installed, wheel shaft is placed on driving member outer wall, the installation groove
The effect of positioning is served, avoids sliding phenomenon between wheel shaft and driving member, occur in use, the groove width of groove is installed
Tapered into from notch toward bottom land direction, further ensured and driving member connective stability and reliability, it is also further to protect
Demonstrate,proved between wheel shaft and driving member is not in sliding phenomenon.
