修理汽车发动机用的轴瓦,一般有如下几种:手工刮削用瓦、搪削用瓦、拉削用瓦、直接进配用瓦。长期以来,供应的发动机修理用轴瓦多为手工刮削用瓦,其次便是搪削用瓦。近年来,随着配件制造厂轴瓦生产质量的提高和采用高锡铝合金制造轴瓦(特别是东风EQ140型汽车发动机轴瓦),直接选配用轴瓦也逐渐多起来了。但有不少汽车修理厂(尤其是一些技术力量较薄弱的修理厂)在购得直接选配用轴瓦后,竟错误认为该轴瓦不合规格,再选用加大一级的轴瓦沿用手工刮削的方法来修配的错误作法。
Repair of automotive engine bearings, generally have the following categories: Hand scraping tile, enamel cutting tile, broaching tile, directly into the use of tile. For a long time, the supply of engine repair with the majority of hand-cranked tile with tile, followed by the enamel cut tiles. In recent years, with the improvement of the production quality of the parts and components bearing bush and the production of bearings made of high-tin-aluminum alloy (especially the Dongfeng EQ140-type automobile engine bearing bush), the direct matching of the bearings also gradually increases. However, many auto repair shops (especially some weak technical repair shops) purchased the direct matching with bushings, they mistakenly think that bushings are out of specification, and then choose to increase the level of a hand-cranked scraping along the way To fix the wrong practices.
