Abstract
The utility model relates to an engine power take-off structure for ships, which comprises a crank shaft positioned inside a crankcase, an intermediate transmission shaft and an output shaft penetrating through the crankcase, wherein, the crank shaft and the intermediate transmission shaft are meshed through gears, the intermediate transmission shaft and the output shaft are meshed through gears, and one pair of gears either between the crank shaft and the intermediate transmission shaft or between the intermediate shaft and the output shaft are bevel gears. The utility model has a high transmission efficiency, which can be increased to about 98%; the intermediate variable-speed process is avoided, so that the booster response is quick; and the utility model has the advantages of simple structure and low cost.
Description
Technical field
The utility model relates to a kind of driving engine, specifically refers to the takeoff output part of marine engine, particularly marine engine.
Background technology
Marine engine is because the driving engine that its special use occasion and land vehicle are used has distinct requirement.Traditional marine engine transmission principle as shown in Figure 1, it mainly is made of bent axle, tween drive spindle and output shaft, realizes transmission by a pair of gear between bent axle and the tween drive spindle, and tween drive spindle and output shaft have five pairs of gears mesh, wherein a pair of transmission, every pair of rotating speed difference of being used for.Existing ship is realized takeoff output with engine output shaft by sprocket wheel, belt etc.At engine interior, transmission direction does not obtain changing, all be to utilize external agency to change the takeoff output direction, complex structure not only, also allow driving engine in the power delivery process, increase a loss in efficiency point simultaneously, reduce the transmission efficiency of driving engine, also improved productive costs greatly.
The utility model content
At the prior art above shortcomings, the purpose of this utility model provides a kind of simple in structure, driving efficiency is high, cost is low marine engine power output structure.
The technical solution of the utility model is achieved in that the marine engine power output structure, comprise bent axle, tween drive spindle that is positioned at crankcase and the output shaft that passes from crankcase, pass through gear mesh respectively between bent axle and the tween drive spindle and between tween drive spindle and the output shaft, it is characterized in that: it is finishing bevel gear cuter that the gear between gear between bent axle and the tween drive spindle or tween drive spindle and the output shaft wherein has a pair of.
Further, described finishing bevel gear cuter is located between tween drive spindle and the output shaft.And tween drive spindle is made up of tween drive spindle I and tween drive spindle II, on bent axle, be provided with gear I, on tween drive spindle I, be provided with gear II and gear III, on tween drive spindle II, be provided with gear IV and finishing bevel gear cuter I, on output shaft, be provided with finishing bevel gear cuter II, gear I and gear II engagement, gear III and gear IV engagement, finishing bevel gear cuter I and finishing bevel gear cuter II engagement.
Described output shaft passes from crankcase bottom.
Compared to existing technology, the utlity model has following beneficial effect:
1, driving efficiency height: the utility model adopts the transmission shaft through-coupling, can not occur skidding, metaboly, and driving efficiency can be increased to about 98%, apparently higher than the driving engine by the exterior mechanical transmission.
2, booster response is fast: the utility model does not have middle speed-change process, so booster response is fast by the output shaft through-coupling.
3, simple in structure, cost reduces: cancelled various parts such as gear on former speed change system, power-transfer clutch, the major-minor axle by improved driving engine, not only simplified the structure, reduced cost simultaneously effectively.

Wherein, 1-bent axle; 2-gear I; 3-gear II; 4-tween drive spindle I; 5-gear III; 6-gear IV; 7-tween drive spindle II; 8-awl tooth I; 9-awl tooth II; The 10-output shaft; The 11-cylinder head; The 12-cylinder body; 13-left side case lid; The right case lid of 14-; The 15-left box body; The 16-right case.
The specific embodiment
The utility model is described in further detail below in conjunction with accompanying drawing.
Referring to Fig. 2, from the figure as can be seen, the utility model marine engine power output structure, comprise bent axle 1, tween drive spindle that is positioned at crankcase and the output shaft 10 that passes from crankcase, pass through gear mesh between bent axle and the tween drive spindle and between tween drive spindle and the output shaft respectively.Improvement of the present utility model is: it is finishing bevel gear cuter that the gear between gear between bent axle and the tween drive spindle or tween drive spindle and the output shaft wherein has a pair of, promptly changes the takeoff output direction at engine interior by finishing bevel gear cuter.
As an embodiment, the utility model finishing bevel gear cuter is located between tween drive spindle and the output shaft, sees Fig. 2 and Fig. 3.And tween drive spindle is made up of tween drive spindle I 4 and tween drive spindle II 7, on bent axle 1, be provided with gear I 2, on tween drive spindle I 4, be provided with gear II 3 and gear III5, on tween drive spindle II 7, be provided with gear IV6 and finishing bevel gear cuter I 8, on output shaft 10, be provided with finishing bevel gear cuter II 9, gear I 2 and gear II 3 engagements, gear III5 and gear IV6 engagement, finishing bevel gear cuter I 8 and finishing bevel gear cuter II 9 engagements.
Fig. 3 is for adopting engine structure figure of the present utility model, from the figure as can be seen, by behind the finishing bevel gear cuter change of direction, output shaft passes from crankcase bottom (diagram below) at engine interior, and (diagram left and right directions) passes and traditional output shaft is from the crankcase side.Among Fig. 3, label 11 is a cylinder head, and 12 is cylinder body, and 13 is left case lid, and 14 is right case lid, and 15 is left box body, and 16 is right case.
The utility model transmission of power is in proper order:
Bent axle-gear I-gear II-tween drive spindle I-gear III-gear IV-tween drive spindle II-awl tooth I-awl tooth II-output shaft, arrow is represented rotation direction among the figure.
Innovation of the present utility model is to use the spiral bevel technology at engine interior, has directly changed the takeoff output direction of driving engine, and designs simplification has improved engine output, has reduced the driving engine cost.Finishing bevel gear cuter both can be located at (as shown in Figure 2) between tween drive spindle II and the output shaft, also can be located between bent axle and the tween drive spindle I, and perhaps between tween drive spindle I and the tween drive spindle II, this does not break away from protection domain of the present utility model equally.
