最近,我们对土法(用煤炉加热)热轧齿轮作了冷轧试验。土法热轧(本刊6期)的精度为4级,经冷轧后普遍提高到2～3级。今将情况介绍如下。一、冷轧齿轮用设备1.机床:SU-63型普通车床。2.夹具:双轧轮径向进给式,结构见下图。导轮18由主轴2自车床床头1得到动力,与分度齿轮10′啮合运转,使冷轧轧轮10作强制迴转。为了保证分度齿轮与冷轧轧轮的同位,两者是作成一体的。工件14(热轧齿轮)的内孔鉝有键槽,装在带外花键的弹簧套筒13
Recently, we conducted a cold rolling test of indigenous law (heating with coal-fired furnaces) hot-rolled gears. Soil hot-rolled (Issue 6) accuracy of 4, after the general increase to 2 to 3 after cold-rolled. The situation will be introduced as follows. First, cold-gear equipment 1. Machine: SU-63-type lathe. 2. Fixture: dual-wheel radial feed, the structure shown below. The guide wheel 18 is powered by the spindle 2 from the bed head 1, meshes with the indexing gear 10 ’, and forcibly rotates the cold-rolling mill 10. In order to ensure that the indexing gear and cold-rolled wheels of the same place, the two are made of one. The inner bore of the workpiece 14 (hot-rolled gear) 鉝 has a keyway and is mounted on a spring sleeve 13 with an external spline
