圓錐滾柱軸承是滾动軸承中用途最广最常見的一种。这种軸承所用的保持架(俗称花籃)一般都是用优質碳鋼板(10号或08号钢板)冲压而成。我厂过去采用的工艺过程如表1所示。用这种制造方法鋼板的利用率仅占投料重量的22～24％;78～76％的金属全部变为废料。这个数字是很惊人的。在我国钢材供应紧张的情况下,大量节約钢材,应提到首要地位。我厂在生产大跃进中,由于技术人員与工人密切结会,大胆地試用了焊接、冲压的工艺方法制造軸承保持架。其具体的过
Tapered roller bearings are the most widely used rolling bearing the most common one. The cage used for such bearings (commonly known as flower baskets) are generally made of high-quality carbon steel (10 or 08 steel) stamping. I used to process the plant shown in Table 1. With this manufacturing method, the utilization rate of the steel sheet accounts for only 22 to 24% of the weight of the raw material; all the metal of 78 to 76% becomes the waste material. This figure is very alarming. In the case of tight supply of steel in our country, a large number of savings in steel, should be mentioned first. I plant in the production of the Great Leap Forward, due to technical staff and workers in close knit, bold trial welding, stamping process of manufacturing bearing cage. Its specific
