一种电锤脱扣结构
本技术涉及一种电锤脱扣结构。
技术介绍
专利号为201420375628.5的中国技术专利公开了一种电锤脱扣装置,包括位于电锤的机身上的下轴承和上轴承,该下轴承和该上轴承内固定有一齿轴,该齿轴上位于该下轴承和上轴承之间从下至上的通过间隙或过渡配合的方式套有弹簧座、通过间隙配合的方式套有下压板、通过间隙配合的方式套有下摩擦片、通过间隙配合的方式套有主动齿轮、通过过盈配合的方式套有上摩擦片、通过过盈配合的方式套有上压板,同时,该齿轴上端位于该上轴承的上方固定有用于带动钻头的从动齿轮,所述弹簧座上设有至少2个开口向上的容纳腔,该容纳腔内均设有一柱形压簧;上述结构中的弹簧座都为一体结构,安装脱扣弹簧的孔一般为冲压而成,因此弹簧座的材质一般都选择铝材质,在长时间的使用中其底部易磨损,这样便需要更换整个弹簧座,使用成本较高,更换过程繁琐。
