The advantages are that: the single-shaft input and double-shaft output are adopted, the adjustable (controllable pitch propeller) propeller for the ship can be synchronously driven in a speed reducing mode, the generator for the ship can be driven in a speed increasing mode, the structure is compact, the maintenance is convenient, the rotating speed and the rotating direction of an output shaft of the gear box do not need to be adjusted in the use process, the reliability of the gear box is improved, and the service life of the gear box is prolonged.
Description
Technical field
The utility model belongs to marine transmission manufacturing technology field, relates in particular to a kind of marine gearbox that drives controllable pitch propeller and generator by marine diesel engine simultaneously.
Background technique
Marine gearbox is a most important transmission device in the boat transmission, and it is responsible for the power that motor sends is passed to propeller cavitation, thereby realizes the motion of boats and ships.By big quantity research patent documentation and the investigation market as can be known, traditional propeller cavitation is that this marine gearbox volume is bigger, the structure more complicated by rotating speed that changes gearbox output shaft and the forward-reverse that sense of rotation realizes boats and ships, efficient is lower, and is difficult in maintenance.Along with succeeding in developing of controllable pitch propeller, traditional marine gearbox can not adapt to the needs with controllable pitch propeller, press for simple in structure, reliability height, the marine gearbox that volume is little and energy-conservation.
Summary of the invention
The purpose of this utility model is: long-pending bigger at traditional marine gearbox, and the structure more complicated, efficient is lower, and is difficult in maintenance, and can not adapt to the practical problem with the needs of controllable pitch propeller, and a kind of gear-box that is used for tuning for Controllable Pitch Propeller peculiar to vessel is provided.
But the purpose of this utility model is achieved in that a kind of gear-box (1) that is used for tuning for Controllable Pitch Propeller peculiar to vessel, comprise casing, input gear shaft, output shaft, it is characterized in that: parallel input gear shaft, output shaft and auxiliary output gear shaft are positioned in the casing by bearings, and the output terminal of input end, output shaft and the auxiliary output gear shaft of input gear shaft all stretches out casing; Also be provided with the driving gearwheel on the input gear shaft, output shaft is provided with the output gearwheel; Output gearwheel engagement on input gear shaft and the output shaft, the driving gearwheel on the input gear shaft and the engagement of auxiliary output gear shaft.
In the utility model: described casing comprises main box body and auxiliary casing, and main box body is connected by intermediate plate with auxiliary casing; Parallel input gear shaft and output shaft are positioned in the main box body by bearings, and auxiliary output gear shaft is positioned in the auxiliary casing by bearings.
In the utility model: the bearing that supports input gear shaft input end is a roller bearing, and the other end is roller bearing and four-point contact ball; The bearing that supports the output shaft output terminal is a selfaligning roller bearing, and the other end is thrust-bearing and tapered roller bearing; The bearing that supports auxiliary output gear shaft output terminal is roller bearing and four-point contact ball, and the other end is a roller bearing.
Advantage of the present utility model is: adopt the output of single shaft input twin shaft, deceleration adjustable (but tuning for Controllable Pitch Propeller) propeller cavitation peculiar to vessel and speedup drive marine generator synchronously, compact structure, easy to maintenance, need not the rotating speed and the sense of rotation of regulating tooth roller box output shaft in the use, improve the reliability of gear-box, prolonged the long service life of gear-box.
