发布时间：2018-12-05 12:30
【摘要】：Y38滚齿机床是目前工程实际中广泛采用的典型齿轮加工设备,由于滚齿机加工渐开线齿轮具有切削连续的特点,加工时效率和精度比较高。文章实现了在Y38滚齿机床上直接加工生产少齿数齿轮,对于少齿数齿轮的推广应用会带来很大的方便。文章分析了滚齿加工过程中,滚刀刀齿各切削刃的切削力的大小以及总的切削力的计算公式。利用MATLAB软件描述滚切过程轨迹,以滚刀和齿轮啮合条件为参数间的不变量,求解出了滚刀切削时在被加工齿轮截面和圆柱面的切削轨迹。研究选择利用范成法原理在Y38滚齿机上加工少齿数的滚切技术,分析Y38滚齿机的传动系统,在理论上实现了少齿数齿轮在Y38滚齿机加工,并对加工中出现的机床无法启动,工作台转速超过规定的极限转速,滚切速度低等问题进行理论分析。在此基础上进行了Y38滚齿机床加工少齿数齿轮改造,用电磁调速异步电机代替机床主电机,连接减速器的方法,实现了在Y38滚齿机床上加工少齿数齿轮,并总结了方案的优缺点。
[Abstract]:Y38 gear hobbing machine is a typical gear machining equipment widely used in engineering practice at present. Because the involute gear machined by gear hobbing machine has the characteristics of continuous cutting, the efficiency and precision of machining is relatively high. This paper has realized the production of gear with less teeth directly on Y38 hobbing machine bed, which will bring great convenience to the popularization and application of gear with less tooth number. In this paper, the size of the cutting force and the calculation formula of the total cutting force of each cutting edge in the hobbing process are analyzed. The MATLAB software is used to describe the path of the hobbing process. The cutting path of the machined gear cross section and cylindrical surface is solved by using the invariant between the hob and the gear meshing condition as the parameter. This paper chooses the hobbing technology of machining less tooth number on Y38 hobbing machine by using the principle of generating method, analyzes the transmission system of Y38 gear hobbing machine, and theoretically realizes the machining of less tooth number gear in Y38 gear hobbing machine, and it can't start the machine tool that appears in the process. The problems of table speed exceeding the specified limit speed and low rolling speed are analyzed theoretically. On the basis of this, the Y38 hobbing machine tool was reformed to process less tooth number gear. The method of connecting the reducer with electromagnetic speed regulating asynchronous motor instead of the main motor of the machine tool was carried out, and the less tooth number gear was machined on the Y38 gear hobbing machine bed. The advantages and disadvantages of the scheme are summarized.
