一种煤矿井下采煤机行走箱用可换式行走轮组件
本技术涉及一种煤矿井下采煤机行走箱行走轮组件。
技术介绍
煤矿井下采煤机行走箱行走轮组件属于开式齿轮传动系统,没有任何润滑,采煤机行走时,有受到大量的截割、自重冲击载荷,造成采煤机行走轮损坏,经常会造成行走轮打齿轮;由于行走轮经常损坏,因此更换频繁,行走轮系统处于传动的末端,更换工序复杂,更换时需要拆销轨、机组落道,并用专用工具拔芯轴,才能取出损坏的行走轮组件;由于井下有煤尘,不利于拆检组装更换,只能整体更换行走轮组件;把新的行走轮组件运输到位进行安装,总体上停产的时间较长。同时,由于行走轮组件加工工艺复杂,而且加工精度要求高,更换行走轮组件的成本较高。
技术实现思路
本技术目的是克服上述已有技术的不足,提供一种装配工序简单、便于更换、可有效降低成本、缩短更换时间的煤矿井下采煤机行走箱上使用的可换式行走轮组件。本技术包括从动轮、从动轮端盖、行走轮、行走轮端盖、滚子轴承和阶梯环密封圈。从动轮为具有外花键的凸台状,凸台内嵌有滚子轴承,行走轮为具有内花键的凹槽状,凹槽尺寸与从动轮凸台尺寸外花键相配,行走轮通过凹槽内花键装配在从动轮凸台外花键上,从动轮与行走轮之间通过花键装配连接为一个整体;从动轮端盖、行走轮端盖分别通过固定螺栓安装在从动轮和行走轮的外侧,滚子轴承套装在芯轴上,可相对芯轴转动并滑动,芯轴通过销轴套支撑在行走箱壳体上,在滚子轴承内套与从动轮端盖、行走轮端盖之间装有阶梯环密封圈,密封轴承防止钙基润滑脂流出外部并阻挡煤尘进入轴承内部。滚子轴承的型号为ZM290A。行走轮齿面渗碳深度2.5-3mm,淬火硬度HRC58 ...
