0.26%, surplus is Fe and a small amount of inevitable impurity.
In this way, axis retainer is made to be fully located in axle journal, and it is completely Chong Die with torsion adjusting spring in electric drill axis direction, from
And reduce the size of gear-box length direction so that the size of charge drill be can be made smaller.In addition, axis retainer passes through ingredient
Limiting has good resistance to deformation and wear-resisting property, while also has preferable low-temperature impact toughness.
The technical solution that further limits of the present invention is：
Foregoing charge drill gear-box, the positioning convex platform on axis retainer is located at the circumferencial direction of axis retainer, by reducing convex
The circumferential lengths of platform reduce the circumferential size of axis retainer, so that the position of axis retainer, which can be located at torsion, adjusts spring
It is interior.
Foregoing charge drill gear-box, the positioning convex platform on axis retainer is located at the circumferencial direction of axis retainer, by reducing axis
The diameter of retainer reduces the circumferential size of axis retainer, is adjusted so that the position of axis retainer can be located at torsion in spring.
Foregoing charge drill gear-box, the positioning convex platform on axis retainer is located on the end face of axis retainer, along the axis of axis retainer
To extension, the positioning convex platform of axis retainer circumferential direction is thus eliminated, the circumferential size for reducing axis retainer while, which nor affects on, to be made
Use effect.
The beneficial effects of the invention are as follows：The position of axis retainer of the present invention is fully located in axle journal, and in electric drill axis direction
Completely Chong Die with torsion adjusting spring, structure is more compact, can effectively reduce the size of gear-box length direction so that fill
The structure of electric drill is more compact, and size be can be made smaller.Axis retainer of the present invention is limited by ingredient, can make the Bu Shi of axis retainer
Hardness is more than 620HB, and tensile strength is more than 1900MPa, and -20 DEG C of ballistic works are more than 30J, have good resistance to deformation and wearability
Can, while also there is preferable low-temperature impact toughness.
