以前口腔科巡回医疗用的牙科治疗机,是在大中型牙机的基础上改进的,但仍存在着体大物重等缺点。为了进一步符合战备要求,为广大指战员防治牙病的需要,我们于1971年试制了一种交直镜微型牙机,体积90立方厘米,重量393克。经过三年来的试用,初步认为这种微型牙机是实用的,现介绍如下。二、设计特点 1.以轻装微型为重点,在以微型电机为动力的基础上进行设计。2.破除传统的传送带式的设计方法,采用将微型电机与车头连接成一个整体,在不损耗电机功
Stomatological treatment of dentistry before the dental treatment machine, is based on the improvement of large and medium-sized dental caliber, but there are still shortcomings such as body weight. In order to further meet the operational readiness requirements and to meet the needs of the vast number of officers and soldiers in preventing and controlling dental diseases, we piloted a micro-dental machine of orthogonal microscope in 1971 with a volume of 90 cubic centimeters and a weight of 393 grams. After three years of trial, initially that this micro-dental machine is practical, are presented below. Second, the design features 1 to light miniature focus, based on the micro-motor as the basis for the design. 2. To get rid of the traditional conveyor belt design method, the micro-motor and the car will be connected as a whole, without loss of motor power
