宁波仪表厂设计制造成功0.001、0.002扇形、双量程测微仪。为我国轴承检测仪表提供了新品种,填补了空白。结构性能特点1.体积小,式样新颖。解决了在一只轴承校验台上不能同时使用多块表头的矛盾。2.机构中磨擦部位,全部采用宝石轴承和宝石平面(共14只),活动元件采用高强度轻合金。3.测杆的支承,改用无磨擦的弹性式结构,从根本上消除了因轴套磨损引起的径向窜动。 Ningbo Instrument Factory design and manufacture of successful 0.001,0.002 fan, dual range micrometer. For our bearing testing instruments provides a new breed, to fill the gap. Structural Features 1. Small size, innovative style. Solve the contradiction between the use of multiple headers can not be used at the same time in a bearing calibration bench. 2 parts of the body friction, all using gem bearings and gem plane (a total of 14), moving parts using high-strength light alloy. 3. Rod support, use non-friction elastic structure, to eliminate the radial shaft movement caused by wear and tear.
