The invention belongs to the technical field of linear motors, and particularly relates to a pulley friction braking type linear motor catapult. A new scheme is provided for the additional braking of a linear motor catapult tackle, and the linear motor catapult tackle can be universally suitable for deceleration braking of driving sliding bodies in various linear catapults through direct transplantation, adaptability improvement or further innovation; the pre-tightening force of a disc spring group in a deceleration module can be adjusted by adjusting the thickness of a gasket group, so that different friction forces can be output during working, and the application range is wide; a modular combination mode is adopted, and various braking combinations with different deceleration characteristic curves can be formed by changing the number of the deceleration modules, the longitudinal mounting positions of the deceleration modules and setting the pre-tightening force of the annular elastic pieces of the deceleration modules, so that diversified working condition requirements are met.
本发明属于直线电机技术领域,具体涉及到一种滑车摩擦制动式直线电机弹射器。本发明为直线电机弹射器滑车的附加制动提供了一种新方案,且通过直接移植、适应性改进或进一步创新,可普遍适用于各型直线弹射器中驱动滑体的减速制动;通过调整垫片组的厚度,可以调整减速模块中碟簧组的预紧力,使其工作时可以输出不同的摩擦力,适应范围广;本发明采用模块化组合方式,通过改变减速模块的数量、各减速模块的纵向安装位置以及各减速模块环形弹性件预紧力的设定,可形成各种具有不同减速特性曲线的制动组合,以满足多样化的工况需求。
