齿轮传动在船舶主动力装置中日益受到广泛采用。它过去的传统使用领域主要是主齿轮传动式涡轮机组,现今它的范围则大大扩展了,这是由于中速柴油机减速装置有了飞速发展以及大量采用多台机组。船舶的排水量不断增大,船用动力装置的功率相应提高,这些都要求创制与之相匹配的齿轮传动装置。同时,鉴于为提高齿轮传动可靠性采取的许多设计和工艺措施收效甚微,大型船用减速器的制造部门面临着大量有关必须提高齿轮强度和可靠性的问题。当然,通过改进和统一计算方法还可挖掘提高减速器强度和可靠性的潜力,但各船
Gear drive is increasingly being used widely in marine propulsion plants. Its traditional use in the past was mainly the main gear-driven turbomachinery, and its scope has been greatly expanded today due to the rapid development of medium-speed diesel gearboxes and the extensive use of multiple units. The ever-increasing displacement of ships and the corresponding increase in the power of marine power units require the creation of matching gearing. In the meantime, given the limited success of many design and process measures to improve gear drive reliability, the manufacturing sector for large marine gearheads faces a significant amount of issues related to the need to increase gear strength and reliability. Of course, the potential to improve the strength and reliability of the reducer can be tapped through improvements and unified calculations, but each
