A half snap ring structure capable of reducing stress concentration of a snap ring groove comprises a snap ring arranged in a semi-ring shape, the section of the snap ring is a composite section formed by combining a triangular section and a semicircular section, the first edge of the triangular section enables the outer wall of the snap ring to be provided with a first conical face, and the second edge of the triangular section enables the inner wall of the snap ring to be provided with a cylindrical face. The straight edge of the semicircular section coincides with the second edge of the triangular section, a connecting part is arranged at the joint of the cylindrical surface and the semicircular structure formed by the semicircular section, a second conical surface is arranged on the inner side of the connecting part, and the upper end of the second conical surface is tangent to the semicircular structure formed by the semicircular section. By adding the connecting part with the second conical surface on the inner side, the contact between the half snap ring and the snap ring groove is surface contact, and the contact surface is the second conical surface on the half snap ring, so that the contact area is increased, the condition of large bearing per unit area is improved, the purpose of reducing stress concentration is achieved, and the service life of a product is prolonged.

    一种具有减小卡环槽应力集中的半卡环结构,包括半环状设置的卡环,卡环的截面为三角形截面与半圆形截面组合成的复合截面,三角形截面的第一条边使卡环外壁具有第一锥形面,三角形截面的第二条边使卡环内壁具有柱型面,半圆形截面的直边与三角形截面的第二条边重合,柱型面与半圆形截面构成的半环状结构连接处设置有连接部,连接部内侧具有第二锥形面,第二锥形面上端与半圆形截面构成的半环状结构相切。本发明通过增加内侧具有第二锥形面的连接部,使半卡环与卡环槽之间的接触为面接触,接触面为半卡环上的第二锥形面,增大了接触面积,改善了单位面积承载大的情况,从而达到减小应力集中的目的,提高了产品的使用寿命。
