Multi-directional rotation variable friction self-resetting damper
The invention discloses a multi-directional rotation variable friction self-resetting damper which comprises a constraint outer friction device, the constraint outer friction device is fixedly connected with a resetting outer friction device through a limiting screw provided with a combined disc spring, and parabolic concave surfaces are arranged in the resetting outer friction device and the constraint outer friction device. An inner friction spherical hinge with a parabolic convex surface characteristic is mounted in an inner space formed by the inner friction plate and the outer friction plate; when the two end parts generate relative displacement, the inner friction spherical hinge with a convex surface inside can generate relative rotation in the constraint outer friction device and the reset outer friction device which are provided with concave surfaces, the convex friction surface and the concave friction surface generate relative rotation friction, and the combined disc spring is compressed to realize variable friction energy consumption; and during unloading, the combined disc spring arranged on the limiting screw rod generates reset force, and then reset is completed.
本发明公开了一种多方位转动变摩擦自复位阻尼器，包括约束外摩擦装置，所述约束外摩擦装置通过设有组合碟簧的限位螺杆与复位外摩擦装置固定连接，所述复位外摩擦装置和所述约束外摩擦装置内均设有抛物线形凹面，两者构成的内部空间安装具抛物线形凸面特征的内摩擦球铰；当两端部发生相对位移时，内部设有凸面的内摩擦球铰将在设有凹面的约束外摩擦装置和复位外摩擦装置内发生相对转动，凸、凹摩擦面将发生相对转动摩擦，并压缩组合碟簧实现变摩擦耗能，卸载时限位螺杆上设置的组合碟簧将产生复位力，进而完成复位。
