具体实施方式
结合图 1 至图 7 所示,具体说明本申请提供的活齿滑块约束弹性复位装置:
利用限位约束挡条 11 与固定销 10 通过固定销安装孔 9 可以非常可靠的将滑块进行约束限位,无需焊接铆接工艺,结构简单,空间紧凑,性能可靠。
本申请另一关键点--弹性复位功能:弹性复位件(弹簧)直径略小于滑块厚度,保证弹簧可以自由伸缩,滑块弹性复位受力区 2 的位置关于滑块中心线偏置,这样装配时让相邻滑块的弹性复位受力区 2 位置相互错位装配,从而给弹簧构造出相对封闭的约束空间,使每一片滑块都能实现独立弹性复位,详见图 7 所示。滑块上的限位约束挡条避让区 3 是为了避让限位约束挡条弹簧约束区 16 ,限位约束挡条弹簧约束区 16 的截面呈梯形或矩形,与其弹簧受力作用区 14 组合共同对弹簧进行约束限位,同时弹簧约束区 16 可以起到加强限位约束挡条强度作用。
从图 7 局部放大图可以明晰看出:相邻滑块与弹簧相互错位组合后,再与限位约束挡条组合,在滑块弹性复位受力区 2 、限位约束挡条避让区 3 、限位约束挡条与弹簧受力作用区 14 、限位约束挡条弹簧约束区 16 共同组合下,弹簧被整体约束在相对封闭的稳定空间(注:最外侧滑块复位弹簧需依靠滑块仓壁进行辅助约束),然后再将此组合体一起装入活齿单元体中,滑块组整体束缚在活齿单元体的滑块仓中,限位约束挡条安装端 15 与 限位约束挡条安装槽 5 配合,再通过固定销 10 插入固定销安装孔 9 中,并与限位约束挡条固定销定位区 13 配合,完成装配全过程。
在活齿滑块工作过程中,滑块复位挡脚 6 与滑块复位挡脚约束面 7 会频繁接触,为延长挡脚寿命,可以在挡脚约束面 7 区域增加减震材料,或改善 挡脚与约束面 相互间表面硬度配比,以起到一定缓冲作用,减小冲击应力。
滑块挡脚可以为不同类型,如:单挡脚活齿滑块 1 、双挡脚活齿滑块 12 。
弹性复位件可以是金属弹簧、非金属弹簧、 气体弹簧、液力弹簧、液力阻尼器等。
另外,滑块 (含滑片) 复位也可以采取 流体(液体或气体)复位,依靠流体的冲击力对滑块进行复位。如:在传动轴的轴心开孔打入高压流体,从轴外圆面的径向孔喷出,对准活齿滑块所在位置进行喷射,可以起到良好复位效果,且可以起到润滑、冷却、清洗滑片作用。
注:本文内容不涉及承载概念,只是对活齿滑块的约束弹性复位方式进行表述,本文提及的滑块,也包括滑片。
