一、前言 对于舰船用齿轮减速器,其齿轮的接触精度是一个很重要的检验项目,然而,舰船用齿轮齿面的接触精度还没有一个很好的检查方法,所以,长期从来一直无法准确的确定齿面的接触精度,过去齿轮的齿面接触精度多采用齿面涂红丹油,在轻微制动下,两齿轮对滚,看其被擦去的痕迹,或是在没有任何涂料和润滑油的条件下,两齿轮在轻微制动下进行对滚,看其被擦高的痕迹,前者由于涂层厚度很难掌握,而且厚度不均匀,所以检查齿轮的接触精 I. INTRODUCTION The contact accuracy of the gear of a ship gear reducer is a very important test item. However, the contact accuracy of the gear tooth surfaces of a ship has not been well examined yet. Therefore, it has not been possible for a long time Accurate determination of the contact surface accuracy, the past gear tooth surface contact accuracy and more use of toothpaste coated red oil, with a slight brake, the two gears on the roll, to see the traces of its wipe, or in the absence of any paint and lubrication Oil conditions, the two gears under the slight braking on the roll, to see it was rubbed traces of the former due to the coating thickness is difficult to grasp, and uneven thickness, so check the gear contact fine
