The invention relates to a multi-tooth type disc spring check ring which comprises a body, the body is of an elastic check ring structure, a plurality of butterfly teeth are distributed on the outer edge of the body in the circumferential direction, and the butterfly teeth extend outwards in the radial direction with the center of the body as the circle center and incline towards the axial side of the body. Parts can be axially fixed, and axial clearances between the parts can be eliminated, so that the axial movement of the parts is prevented. The problem that parts axially float when the circlip for the shaft is independently used is effectively solved, and meanwhile the problems that the assembly structure is complex and the cost is increased due to the fact that the disc spring must be combined with the circlip or a thread fastening structure for use in a complete set at the same time are solved. The invention further relates to an installation structure of the multi-tooth type disc spring check ring, the axial gap between the flywheel and the installation groove is effectively eliminated, the assembly precision is improved, meanwhile, power loss of the flywheel is avoided, and the transmission efficiency is guaranteed.

    本发明涉及一种多齿式碟簧挡圈,包括本体,所述本体为弹性挡圈结构,本体的外缘沿周向分布有多个蝶形齿,所述蝶形齿以本体中心为圆心沿径向向外延伸,并向本体轴向的一侧倾斜。既可以轴向固定零件,又可以消除与零件之间的轴向间隙,从而防止零件轴向窜动。有效解决单独使用轴用弹性挡圈时零部件轴向窜动的问题,同时也解决了碟簧必须同时和弹性挡圈或螺纹紧固结构组合成套使用导致装配结构复杂,成本增加的问题。本发明还涉及一种多齿式碟簧挡圈的安装结构,有效消除飞轮与安装槽之间的轴向间隙,提高了装配精度,同时避免飞轮功率损失,保证传动效率。
