编辑同志: 我阅读了贵刊1983年第7期“国外书刊摘要”栏关于美国阿联牛顿公司新发明的“X-Y型减速器”(即“新型超高减速器)的报道,很有启发。该减速器只用三个主要零件(内齿环、外齿环和控制板),结构非常简单,却可达到很大的减速比。我所有一项目,其中不锈钢丝网圆管必须采用氩弧焊,焊机的行程速度为50mm/min左右。这种超低速行程,虽经多方设法,都未得到解决,影响了科研的进度。我根据贵刊的报道,制造了一台X-Y型减速器,出轴转速0.5rpm,使行程速度达到50mm/min, Editor comrades: I read your magazine No. 7, 1983 “Foreign Abstracts” column on the United States Newton’s invention of the “XY reducer” (that is, "new ultra-high gear reducer) of the report, very inspired. The reducer only three main components (internal gear ring, external gear ring and control panel), the structure is very simple, but can achieve a large reduction ratio.All of my projects, including stainless steel wire mesh tube must be used argon arc Welding, welding machine travel speed of 50mm / min or so .This ultra-low speed travel, despite many ways, have not been resolved, affecting the progress of scientific research.I produced according to your publication, an XY-type reducer , The shaft speed of 0.5rpm, the stroke speed of 50mm / min,
