Abstract

The invention discloses a gearbox special speed ratio structure, and relates to the field of transmission devices. The gearbox special speed ratio structure comprises a box body, wherein an ahead running transmission gear is fixedly arranged in an input shaft of the box body, an ahead running clutch is arranged in the ahead running transmission gear, an ahead running driving gear sleeves the inputshaft, the ahead running driving gear is engaged with the ahead running transmission gear fixedly mounted on an output shaft, a driven gear is meshed with a reversing driving gear, the reversing driving gear sleeves a transmission shaft, a reversing clutch is arranged in a reversing transmission gear fixedly mounted on the transmission shaft, and the output end of the output shaft is provided with an output shaft joint for outputting power; and the ahead running transmission gear meshes with the reversing transmission gear. The gearbox special speed ratio structure has the beneficial effectsthat when the rotating speed of a diesel engine of an existing yacht, a working boat and a speed yacht is not enough, the speed can be improved by connecting a gearbox, so that the working condition of a high-speed propulsion device is met.

Description

technical field [0001] The invention relates to the field of transmission devices, in particular to a special speed ratio structure of a gear box. Background technique [0002] Present yachts, working boats, speedboats, etc. use a large number of high-speed propulsion devices. When the speed of these devices is higher than the speed of diesel engines, gear boxes are required to increase speed to reach the operating conditions. At the same time, the marine gearbox has the requirement of reverse drive, and the drive gear on the input shaft and the reverse drive gear on the transmission shaft form a transmission pair. Respective clutches are housed in respective transmission gears, and when driving along, the driving clutches are combined, and when reversing, the reverse clutches are combined. The center distance of the two transmission gears is determined according to the requirements of the transmission gears. For example, when the gear box is required to increase speed, wh...
