PURPOSE:To make compact a whole equipment in which a variable-speed fluid coupling and an overdrive gear unit are provided between a driver and a rotary machine, by integrating the output or input impeller of the coupling with one gear of the overdrive unit. CONSTITUTION:A variable-speed fluid coupling 4 comprises an input impeller 16 integrated with an input shaft 6, an output impeller 18 integrated with an output shaft 17, an inner casing 19 mounted on the output impeller and covering the input impeller, and a scoop pipe 20. The output impeller 18 is integrated with a large gear 8, which is engaged with a small gear 11 so that an overdrive gear unit 5 is consturucted. The shaft 21 of the small gear 11 is connected to the impeller of a compressor not shown in the drawing. According to this constitution, the whole equipment is made compact and the production cost is reduced. |
