本文介绍了柴油机,主要是Д100系列柴油机的滚压强化。本文共分六部分;1)曲轴轴颈圆角的滚压方法; 2)曲轴轴颈圆角的滚压装置; 3)滚压工艺对硬度和残余应力的影响; 4)曲轴用滚子滚压后疲劳强度的提高; 5)滚压过程对曲轴变形的影响;6)制订Д100系列柴油机曲轴滚压强化工艺过程的基本原则。前三部分已在本刊今年第七期上介绍,现继续介绍后三部分。
This article describes the diesel engine, mainly Д100 series diesel engine rolling strengthening. This paper is divided into six parts: 1) Rolling method of crankshaft journal fillets; 2) Rolling device of crankshaft journal fillets; 3) Effect of rolling process on hardness and residual stress; 4) 5) the impact of rolling process on the deformation of the crankshaft; 6) to develop the basic principles of Д100 series diesel engine crankshaft rolling to strengthen the process. The first three parts have already been introduced in the seventh issue of this year, and we are going to introduce the latter three parts.
