我厂1140型柴油机顶杆座乙(以下简称挺杆)与凸轮在装机运转中所发生的刮伤问题,在摒除凸轮磨削烧伤之后有了很大好转,但并未得到彻底的解决,仍然是生产上的一个关鍵。我们从《内燃机快报》(1965年第11期)“发动机凸轮润滑”一文中关于磷化处理运用了润滑抗压耐磨方面的报道而得到启发,并采用了热磷化处理来防止挺杆与凸轮产生刮伤,经过多次试验,获得了成功,并正式用于生产。现将我们的试验方法及其结果介绍如下。 I plant 1140 Diesel jack B (hereinafter referred to as tappet) and the cam in the installed operation of the scratch occurred in the exclusion of cam grinding burn has been greatly improved, but has not been completely resolved, still Is a key production. Inspired by the article “Engine Cam Lubrication” in the “ICE Bulletin” (Issue 11, 1965) on the use of lubricated compressive and wear resistant phosphating, we used a thermal phosphating treatment to prevent the tappet and Cam scratches, after many tests, was successful, and formally used in production. Now our test methods and the results are as follows.
