Abstract
The utility model relates to a small scale high-speed marine gearbox, in particular to a gear power transmitting device, a metal elastic coupler is connected to an engine, wherein the metal elastic coupler is connected with an input shaft via splines and can axially slide, and a drive gear of the gearbox is arranged on the input shaft or a reverse clutch shaft via supporting of a sliding sleeve. The small scale high-speed marine gearbox can eliminate or reduce vibration of the power system, relieve impaction when ships are started, accelerated or reversed in direction, prevent the ships from violent shake, and reduce noise, thereby promoting quality of the ships.
Description
Technical field
The utility model relates to a kind of miniature high-speed marine gearbox, especially a kind of gear transmission transfer unit.
Background technique
In the technique known, for guaranteeing the good maneuverability of ship, use the rubber elasticity connecting mode between gear-box and the motor, gear-box inside is arranged in parallel two cover wet type hydraulic couplinges, and the forward-reverse of ship is controlled by the clutch of steerage gear case inside.All there is bigger impact in existing gear-box when ship startup, acceleration or commutation, make ship give birth to big rocking and noise.
Chinese patent CN2631940, a kind of light high-speed marine gearbox is disclosed, two driving gears of described input shaft and transmission shaft respectively are placed on the axle by sliding bearing, clutch on the axle is provided with piston on one side, this piston links to each other with hydraulic operating system on being installed in casing by interior oil circuit hydraulic fluid chamber, the marine gearbox of this structure can not solve hull stability at the volley.
Summary of the invention
The purpose of this utility model is to overcome the deficiency of above-mentioned existence, provides a kind of rational in infrastructure, in light weight, easy for installation, the miniature high-speed ship special gear box that reliability is high.
Above-mentioned technical problem of the present utility model is mainly solved by following technical proposals:
A kind of miniature high-speed marine gearbox, with input shaft, transmission shaft and output shaft respectively by Bearing Installation on gear housing, gear-box connects with motor, driving gear and sliding sleeve and driving gear are installed on the input shaft, clutch is housed in the middle of two gears, driving gear and driving gear and interposed clutch are installed on transmission shaft too, described gear-box input end is provided with the metallic elastic coupling, the big end of metallic elastic coupling connects with engine flywheel, the small end and the gearbox input shaft of metallic elastic coupling link, and can endwisely slip.The metallic elastic coupling has high elasticity, can make the gearbox more stable work, effectively eliminates or alleviate the vibration of power system.
As preferably, the driving gear of described clutch is supported on input shaft or the reverse clutch axle with sliding shaft sleeve.
As preferably, described metallic elastic coupling is provided with internal spline.
As preferably, described input shaft is provided with external splines.
As preferably, the external splines on the described input shaft is plugged in the internal spline on the metallic elastic shaft coupling.
In technique scheme, the vibration of power system can be eliminated or alleviate to the metallic elastic coupling, makes gear-box more simple and reliable with connecting of motor, and power transmission is soft.When the ship's speed variation causes load change, can play buffer function to power system.Driving gear supports the running accuracy can improve gear with sliding shaft sleeve, is fit to the relative high speed rotating of generation between gear and the axle, increases the service life.Impact when the utility model can reduce the ship startup, quickens or commutate avoids ship to give birth to big rocking, and alleviates noise, promotes the class of ship.
Description of drawings
Fig. 1 is a structural representation of the present utility model;
Fig. 2 is the utility model structure enlarged view.
Embodiment
Below by embodiment, and in conjunction with the accompanying drawings, the technical solution of the utility model is described in further detail.
Embodiment: as shown in Figure 1 and Figure 2, the big end of described metallic elastic coupling 1 connects with engine flywheel 7, flywheel and case 8 companies of linking; The input shaft 2 of small end and gear-box 11 is used splined, can endwisely slip between metallic elastic coupling 1 and the gearbox input shaft 2.External splines 12 on the input shaft is plugged in the internal spline 13 on the metallic elastic shaft coupling 1, and external splines 12 and internal spline 13 closely cooperate.Two tapered roller bearings of clutch 3 usefulness are supported on casing and the case lid assembly, the driving gear 4 usefulness sliding shaft sleeves 5 of wounded in the battle key are supported on the input shaft 2, be provided with heat exchanger 9 on the top of clutch 3, two tapered roller bearings of output shaft assembly 6 usefulness are supported on casing and the case lid assembly, and output block 6 connects with propeller cavitation 10.
During engine revolution, by 2 rotations of metallic elastic coupling 1 driven gear case input shaft, simultaneously, the gear-box oil pump begins fuel feeding, this moment, clutch 3 was in disengaged condition, and driving gear 4 produces by sliding shaft sleeve 5 and 2 of input shafts and slides, and output shaft assembly 6 does not rotate.When control valve imports ahead running clutch 3 oil cylinders when promoting piston pressing friction sheet with pressure oil, driving gear 4 rotates synchronously with input shaft 2, drives output shaft, and output shaft turns on the contrary with motor at this moment, and boats and ships advance.When control valve imports the reverse clutch oil cylinder when promoting piston pressing friction sheet with pressure oil, the ahead running throw-out-of clutch, the reversing driving gear rotates synchronously with the reverse clutch axle, drives output shaft, and output shaft turns to identically with motor at this moment, and boats and ships retreat.
