再制造双圆弧齿轮单齿切削机床设计

目前抽油机减速器双圆弧齿轮使用一段时间后会出现单个齿破损或多个齿间隔破损的情况，现有的修复方法效率低。针对这种情况，提出设计一种对修复后的再制造双圆弧齿轮进行再加工的切削机床，验证再制造双圆弧齿轮单齿加工的可行性。结合再制造双圆弧齿轮单齿展成加工理论，对单齿加工机床的刀具运动部件、齿向螺旋进给部件、齿形展成进给部件以及工件运动部件进行设计,最终得到满足加工要求的再制造双圆弧齿轮单齿切削机床。分析再制造双圆弧齿轮单齿加工的误差后，提出一种减小再制造双圆弧齿轮轴向齿距误差的方法。

Design of Remanufacturing Double Circular Arc Gear Single Tooth Cutting Machine Tool

At present, the pumping machine reducer double circular arc gears is broken after a period of time with a single tooth or multiple teeth broken at intervals, and the existing repair methods are inefficient. In response to this situation, a cutting machine tool was proposed to design a remanufactured double arc gear for reworking after repair, and the feasibility of single tooth machining of remanufactured double arc gear was verified. Combined with the theory of single tooth spreading machining of remanufactured double arc gears, the design of tool motion parts, tooth directional spiral feed parts, tooth spreading feed parts and workpiece motion parts of the single tooth machining machine was carried out, finally the single tooth cutting machine of remanufactured double arc gear that could meet the machining requirements was acquired. After analyzing the error of single tooth machining of remanufactured double arc gears, a method was proposed to reduce the error of axial tooth pitch of remanufactured double arc gears.
