Description

一种框架锯锯框双向复合导向支承机构 技术领域
本发明涉及一种导向支承机构,具体是一种为锯解大理石及花岗石用的金刚石框架锯的锯框提供支承和导向作用的复合导向支承机构,属于石材机械设备技术领域。
背景技术
在金刚石框架锯的运行过程中,锯框的运行路线对于加工板材质量及精度有着至关重要的影响。在石材的锯解过程中,锯框会承受相应的锯解反作用力(包括法向力,切向力与侧向力),导致锯框的运行受到干扰,从而出现加工误差。对于大型荒料的锯解,这些问题是致命的。此外,目前金刚石框架锯锯框的常用导向支承机构一般设置在支撑轴的端部,因此存在支承轴受弯矩较大的问题;且导向支撑机构都较为复杂、不够紧凑,支承轴一旦断裂,将出现严重的安全事故,对人身安全与财产安全造成损害。因此,有必要设计一种新型的导向支承机构改善目前的状况。
发明内容

进一步的,所述支承轴中部设有阶梯型轴环,辅助向心轴承与推力轴承实现轴向定位;工作时,轴环将侧向载荷通过推力轴承作用在滑块的端部;
进一步的,所述滑块由耐磨高韧性材料制成,将侧向载荷通过接触作用在轴承座上进而传递到机架上。
进一步的,所述导轨座为组合结构,可以拆卸以方便机构的装卸;导轨座整体为矩形立体结构,侧壁留有供支承轴安装与位移的槽,导轨座下半部分可以存留润滑物质以改善导向支承机构的工作环境。
