在机械修理中,对不能修复的零件采用更换新的配件的办法。但有一些进口数量少的专用设备,由于个别重要损坏件因各种原因买不到配件,无法及时更换,造成了该设备不能运转。为了不使这些机械设备由于某一部件的损坏而停待或报废,仿制原件不失为一种有效的修复方法。1 仿制范围对于一般的机械设备来说,几乎所有的零件都可以仿制,如果从技术、经济方面考虑,仿制单件(或数量不多)应局限在皮带轮、飞轮、联轴器,普通齿轮,传动轴、钢结构件、普通磨损件等。 In mechanical repairs, new parts are replaced with parts that cannot be repaired. However, there are some special equipment with a small number of imports. Because some important damaged parts cannot be purchased for various reasons, they cannot be replaced in time, causing the equipment to fail to operate. In order to prevent these mechanical devices from being stopped or scrapped due to the damage of a certain component, copying the originals is an effective method of repair. 1 Reproduction range For general mechanical equipment, almost all parts can be imitated. If technical and economic considerations are taken, the imitation of a single piece (or a small number) should be limited to pulleys, flywheels, couplings, and common gears. Transmission shaft, steel structure, general wear parts, etc.
