Abstract
The utility model discloses a splined shaft. The splined shaft comprises a shaft body, wherein the shaft body is provided with a first spline, a third spline, a fourth spline, a bearing neck and a second spline from left to right in sequence; the left end of the fourth spline is provided with a shaft shoulder; and a tool withdrawal groove is formed between the fourth spline and the bearing neck. Through the splined shaft, parts sleeved on the splined shaft are precisely matched, so that the abrasion and damage condition during working process are greatly reduced, and the service life is prolonged.
Description
Technical field
The utility model relates to splined shaft.
Background technique
Splined shaft is as the component that transmit mechanical torque, most applications requires the external component that is sleeved on the splined shaft is carried out precision positioning, yet the splined shaft of prior art only is external component to be carried out rough location make it follow the splined shaft action, make like this very big wearing and tearing to occur between the external component and splined shaft in the working procedure, even directly cause splined shaft to damage.
Summary of the invention
Problem to be solved in the utility model provides splined shaft, and the feasible component precision-fit that is sleeved on the splined shaft reduces the wear damage situation in the working procedure greatly, prolongs operating life.
In order to solve the problems of the technologies described above, the utility model adopts following technological scheme: splined shaft, comprise axis body, be provided with first spline, the 3rd spline, the 4th spline, bearing neck and second spline on the described axis body from left to right successively, the left end of described the 4th spline is provided with the shaft shoulder, is provided with first tool withdrawal groove between described the 4th spline and the bearing neck.By the shaft shoulder and bearing the external component that is sleeved on the 4th spline is carried out axially locating, and first tool withdrawal groove makes the end face of external component and bearing to fit tightly.
Improved, described the 4th spline comprises spline I and spline II, and described spline I and spline II arrange at interval.Outside component axial is located, and strengthened the intensity of self, improve and damage phenomenon.
Improved, be provided with second tool withdrawal groove between described the 3rd spline and the shaft shoulder.Make the external component that is sleeved on the 3rd spline to closely cooperate with the end face of the shaft shoulder.
Improved, the end face of described first spline is provided with screw hole.
Improved, be equipped with quench-hardened case on the surface of described second spline, the 3rd spline, the 4th spline and bearing strength, the degree of depth of described quench-hardened case is 1.2～2mm.Strengthen the intensity of self, avoid abrasion condition.
Beneficial effect:
After adopting technique scheme, the feasible component precision-fit that is sleeved on the splined shaft of this model utility splined shaft reduces the wear damage situation in the working procedure greatly, prolongs operating life.
