Title (EN) CONSTANT-FORCE SPRING
(FR) RESSORT À FORCE CONSTANTE
(ZH) 一种恒压弹簧
Abstract:
(EN) The invention relates to the field of mechanical components, and specifically, to a constant-force spring, resolving a problem in which it is not possible to keep an elastic force of a conventional spring constant. The constant-force spring comprises a cylindrical main body (1) made up of an elastic material. The outer periphery of the main body is a concave surface (11) bending inwards at a middle section thereof in an axial direction. The inner periphery of the main body is a convex surface (12) bending outwards at a middle section thereof in an axial direction. When operated in a defined compression range, the constant-force spring can produce a constant elastic force.
(FR) L'invention concerne le domaine de composants mécaniques, et spécifiquement, un ressort à force constante, résolvant un problème dans lequel il n'est pas possible de maintenir une force élastique d'une constante de rappel classique. Le ressort à force constante comprend un corps principal cylindrique (1) composé d'un matériau élastique. La périphérie extérieure du corps principal est une surface concave (11) se courbant vers l'intérieur au niveau d'une section centrale de celui-ci dans une direction axiale. La périphérie intérieure du corps principal est une surface convexe (12) se courbant vers l'extérieur au niveau d'une section centrale de celui-ci dans une direction axiale. Lorsqu'il est actionné dans une plage de compression définie, le ressort à force constante peut produire une force élastique constante.
(ZH) 一种恒压弹簧,属于机械部件技术领域。它解决了现有弹簧的弹力难以保持恒定的问题。恒压弹簧包括呈筒状的本体(1),本体采用弹性材料制成,本体的外周面是一个轴向的中部向内凹的凹面(11),本体的内周面是一个轴向的中部向外凸的凸面(12)。本恒压弹簧能够在一定压缩程度范围内产生的弹力保持恒定。
