The invention relates to the technical field of helicopter intermediate speed reducers, and discloses an intermediate speed reducer and a helicopter. The input gear corresponds to one opening and is installed and supported through a first bearing set. The output gear corresponds to the other opening and is installed and supported through a second bearing set. Oil ways are formed between a first oil pocket formed on the casing assembly and the first bearing set and between the first oil pocket formed on the casing assembly and the second bearing set, an oil pool is formed in the containing cavity, and part of gear teeth of the input gear and part of gear teeth of the output gear are arranged in the oil pool. When an input gear in the intermediate speed reducer rotates, after gear teeth pass through the oil pool, part of lubricating oil is adhered between the gear teeth, the lubricating oil splashes outwards under the action of centrifugal force, part of the lubricating oil enters the first oil pocket and flows to the first bearing pack or the second bearing pack through the oil way, and then the first bearing pack or the second bearing pack is lubricated and cooled; meanwhile, the heat dissipation performance of the intermediate speed reducer is improved.
本发明涉及直升机中间减速器技术领域,公开了一种中间减速器及直升机,中间减速器包括:机匣组件内部形成容纳腔,两端开口设置;输入齿轮对应一个开口设置并通过第一轴承组安装支撑;输出齿轮对应另一个开口设置并通过第二轴承组安装支撑;机匣组件上形成的第一油兜分别与第一轴承组和第二轴承组之间形成有油路,容纳腔内形成油池,输入齿轮的部分轮齿和输出齿轮的部分轮齿设置于油池内。本发明在中间减速器内输入齿轮旋转时,轮齿经过油池后,轮齿间会粘带部分滑油,滑油在离心力的作用下向外飞溅,部分滑油进入到第一油兜内并通过油路流向第一轴承组或第二轴承组,进而对第一轴承组或第二轴承组进行润滑和冷却,同时提高了中间减速器散热性能。
