The invention discloses a guide rail and guide wheel structure with a guide function and an automatic compensation function. The guide rail and guide wheel structure comprises a V-shaped guide rail and a V-shaped guide wheel, a rolling bearing is arranged in the center of the V-shaped guide wheel in the axial direction, the V-shaped guide wheel is in rolling fit with the V-shaped guide rail, and the included angle between working faces of the V-shaped guide rail is equal to that between generatrices of the working faces of the V-shaped guide wheel; and process compensation grooves are formed in the end parts of the working surfaces of the V-shaped guide rail. According to the guide rail and guide wheel structure, the V-shaped guide wheel and the V-shaped guide rail which are matched with each other are arranged, a rolling bearing is arranged on the V-shaped guide wheel, the rolling bearing makes contact with a carrier weight, sliding friction of a linear sliding rail is changed into rolling friction, the lubricating requirement is lowered, and the machining cost is reduced; and meanwhile, through the process compensation grooves, the guide precision is kept unchanged, meanwhile, the problem that a common guide rail and guide wheel is poor in guide precision is solved, and the precision and efficiency of the guide process are better guaranteed.
本发明公开了一种具有自动补偿功能的带导向功能导轨导轮结构,包括V形导轨和V形导轮,所述的V形导轮中心轴向设置有滚动轴承,所述的V形导轮与V形导轨滚动配合,V形导轨工作面之间的夹角与V形导轮工作面母线之间的夹角相等,所述的V形导轨工作面端部设置有工艺补偿槽。本发明通过设置相互配合的V型导轮和V型导轨,在V行导轮上设置滚动轴承,通过滚动轴承与载体重物接触,把直线滑轨的滑动摩擦变为了滚动摩擦,降低了润滑要求,降低了加工成本,同时工艺补偿槽,保证了导向精度不变的同时,也克服了普通导轨导轮导向精度差的问题,更好的保证了导向过程的精度和效率。
