转速高和节线速度高,是高速齿轮传动装置本身固有的两种困难。透平机械功率不断地增大,也导致了齿轮尺寸可观地增大、其节线速度如此之高,以致要求对齿轮给预特殊的考虑。由于高速齿轮传动本身存在的最大难题之一是包括整个齿轮传动系统在内的及其复杂的热效应问题。所以,作者制造了一个全尺寸齿轮装置并使其在26,165马力,18,633/4730转/分的工况下运行。本文主要论述在运转条件下,齿轮传动装置热特性的测定。 High speed and high pitch speed are two inherent problems with high-speed gear drives. Continued increases in turbine mechanical power have also led to a considerable increase in gear size with so high nodal speeds that pre-special consideration is required for the gear. Due to the high-speed gear transmission itself, one of the biggest problems is that including the entire gear transmission system, including its complex thermal effects. So, the author built a full-size gear unit and ran it at 26,165 hp at 18,633 / 4730 rpm. This paper mainly discusses the determination of the thermal characteristics of the gear transmission under operating conditions.
