Abstract

진동의 전달을 저하하고, 포켓의 내부면과의 볼의 충돌에 의해 발생되는 해머링 노이즈를 방지하기 위해서, 정속 조인트는 내측 결합홈과 외측 결합홈에 인접하게 포켓 내에 유지된 볼과, 볼의 회전부내에 포위된 0.13 또는 그 이하의 마찰 계수를 가지니 그리이스를 가진다. 그러므로 볼은 부드럽게 이동하여 포켓의 내부면과의 볼의 강력한 충돌을 제거하므로써, 해머링 노이즈의 방생을 방지한다.In order to reduce the transmission of vibration and to prevent hammering noise caused by the collision of the ball with the inner surface of the pocket, the constant velocity joint is a ball held in the pocket adjacent to the inner engaging groove and the outer engaging groove, and the ball rotating portion. It has grease with a coefficient of friction of 0.13 or less enclosed within. Therefore, the ball moves smoothly to eliminate the strong collision of the ball with the inner surface of the pocket, thereby preventing generation of hammering noise.

Description

정속 조인트Constant speed joint

본 내용은 요부공개 건이므로 전문내용을 수록하지 않았음Since this is an open matter, no full text was included.

제1도는 본 발명에 관한 정속 조인트를 도시하는 단면도.1 is a cross-sectional view showing a constant velocity joint according to the present invention.

제2도는 조인트 각이 제로로 설정될때 제1도의 선 A―A를 따라 취한 단면도.FIG. 2 is a sectional view taken along the line A-A of FIG. 1 when the joint angle is set to zero.

제3도는 외부링이 생략되어진 제2도의 상부에서 본 볼과 포켓을 도시하는 다이어그램.3 is a diagram showing the ball and pocket seen from the top of FIG. 2 with the outer ring omitted.

제4도는 볼의 위치와 해머링 노이즈의 발생 사이의 관계를 나타내기 위해 제1도의 화살표 B이 방향으로 본 볼을 도시하는 다이어그램.4 is a diagram showing the ball viewed in the direction indicated by arrow B in FIG. 1 to show the relationship between the ball position and the generation of hammering noise.
