一、简述 活塞在内燃机中处于高温、高压、高速、冲击荷载的情况下运动,它传递动力、散发热量,是内燃机的关键部件之一,对其质量有较高要求。在生产和经营中,一般对尺寸公差、理化性能指标往往比较重视,建立了完善的质保手段,这些指标一般能达到质量分等要求,而毛刺、清洁度这些表面质量问题在生产中很常见,但又被忽视。它对整个汽配行业以至内燃机行业的影响重大,有必要进行剖析,其主要危害有:
First, a brief description Pistons in the internal combustion engine at high temperature, high pressure, high speed, impact load movement, it transmits power, heat dissipation, is one of the key components of the internal combustion engine, the quality of its higher requirements. In production and management, the general size tolerance, physical and chemical performance indicators tend to pay more attention to establish a sound means of quality assurance, these indicators generally meet the quality classification requirements, and burr, cleanliness of these surface quality problems are common in the production, But neglected. It has an important impact on the entire auto parts industry and the internal combustion engine industry. It is necessary to conduct an analysis. The main hazards are as follows:
