巷道掘进机支重轮式行走机构

Supporting Wheel Walking Struction of Tunnelling Roadheader

巷道掘进机支重轮式行走机构,改变了原来支重轮与履带板靠摩擦运转的方式,采用齿轮齿条啮合原理进行了结构创新,保证支重轮长期工作下的正常转动,可有效防止支重轮在工作过程中偏磨,以延长支重轮的使用寿命。

Supporting wheel walking struction of Tunnelling Roadheader described,changed the way the original supporting wheel and crawler board by friction operation,the gear rack engagement principle of structure innovation,to ensure the normal operation of supporting wheel under the long-term working, can effectively prevent the supporting wheels in the working process of eccentric wear, to extend the service life of supporting wheel.
