Description
Technical field
The present invention relates to marine drive (marine drive).
Background technology
Marine drive can be divided three classes easily.They are:
(i) inboard engine;
(ii) outboard engine;
(iii) stern actuator (stern drive).
Inboard engine and outboard engine are discussed in 845 the preamble in US Patent 6,186, this patent disclosure an a kind of embodiment who is called the actuator of stern actuator.In this actuator, engine installation is gone up or the inboard of the horizontal material of tail at the horizontal material of the tail of ship (transom), and its axle drive shaft passes and leads to gear cluster and the propeller shaft that is positioned at the fairing lower end in horizontal material of tail and the fairing outside hull downwards.
Must derive from two factors by technical complexity to be processed in the actuator on the quarter.At first, fairing must be around the rotation of vertical or vertical substantially axis, thereby guides angle of rake thrust with respect to the front and back straight line with an angle, turns to allowing.The second, must can " brachymemma " fairing, that is to say fairing is tilted to change its gradient around horizontal axis.This guides angle of rake thrust with on even keel or with respect to horizontal direction with the angle of needs.This motion also is used for the lifting fairing so that ship can be loaded onto on the trailer or sail to the bank.
US Patent 6,186,845 specification sheets disclose a kind of stern actuator, the banking motion of the fairing that the gradient of the divertical motion of its permission fairing and adjustment fairing is required, and allow fairing to be lifted so that ship can be placed on the trailer.
PCT specification sheets WO 2004/085245 discloses another stern actuator.Though do not really want the tabulation that provides tediously long, in US Patent specification 6,468,119,5,601,464,4,037,558,3,847,108 and 3,166,040 also discloses other forms of stern actuator.
Traditional stern actuator is based on such layout: the crank shaft of engine drives output shaft by universal coupling, perhaps more commonly by two universal couplings.Propose to use the constant speed plunging joint to replace universal coupling.Output shaft be level or basic horizontal, and drive a gear cluster, the output shaft of gear cluster is vertical or vertical substantially.This vertical output shaft drives lower tooth wheels, and these lower tooth wheels drive propeller shaft again.
Gimbal table (gimbal) is provided, and it is carrying driving engine and is being installed on the fixed part of ship.Gimbal table is generally used for around vertical or approaching vertical axial-movement.Spindle arm is connected in this gimbal table.By the vertical installation axis rotation gimbal table around gimbal table, this gimbal table and whole fairing can be shifted around the vertical axis of gimbal table, thereby guide angle of rake thrust and make ship to turn to an angle with respect to the front and back straight line of ship.
Fairing is installed on the gimbal table round the axis of approximate horizontal.By utilize one or more pressure cylinders (ram) around this horizontal axis with respect to gimbal table this fairing that tilts, this fairing can be received short (trim up or down) up or down, so that store.
Be arranged on the universal or constant speed plunging joint of crank shaft between horizontal output shaft and allow these axles when fairing and gimbal table (around vertical steer axis) are mobile, relative to each other to move, and allow to move with respect to gimbal table (around the receipts minor axis (trim axis) of level).
A version of this standard system becomes feasible commercial recently.In this form, gimbal table is installed aboard ship so that move around horizontal axis with fairing, makes fairing can receive weak point.This fairing is installed on the gimbal table so that move around vertical axis with respect to gimbal table.For the purpose that turns to, spindle arm is shifted with respect to gimbal table fairing around this vertical axis.
US Patent specification 6,186,845 mounting structure has been avoided the use universal coupling, but has such shortcoming: whole driving engine and fairing are moved in receiving short motion.This means except driving engine occupied space, its normal position, also must provide additional space, and for storing purpose when lifting fairing, driving engine can move in this space.
The gear cluster of above-mentioned traditional stern actuator can comprise: by the first taper pinion of the crankshaft drives of driving engine, with engagement of the first taper pinion and first and second finishing bevel gear cuters of rotation round about, be used for first finishing bevel gear cuter or middle tap gear are connected to the reverse clutch of first lateral shaft.This first lateral shaft will thereby rotation in the opposite direction, this depends on that coupled is first or the middle tap gear.The rotation of first lateral shaft is passed to output shaft.
First and second finishing bevel gear cuters coaxially are carried on first lateral shaft, be in the opposite both sides of the first taper pinion, and power-transfer clutch thus be used for first or the middle tap gear be connected to first lateral shaft, thereby between forward and reverse state, change the hand of rotation of output shaft.Each first and second finishing bevel gear cuter can have outshot, defines bevelled interface, and power-transfer clutch can comprise the clutching member between first and second finishing bevel gear cuters, and clutching member is connected to first lateral shaft by helical spline.By endwisely slipping on first lateral shaft, clutching member can be connected to first or the middle tap gear, and engages with the conical clutch face of one of two finishing bevel gear cuters.
The orientation of helical spline makes: if clutching member be connected to first or the middle tap gear in the lump moment of torsion is delivered to first lateral shaft from finishing bevel gear cuter, then be pulled into certain finishing bevel gear cuter and engage by clutching member and this clutching member of mutual action between the spline.As a result, power-transfer clutch keeps engaging, and moment of torsion is transmitted and needs very little power to come engaging clutch simultaneously.But, overcome from engaging the spline effect and the required power of cut-off clutch may be very big.The mechanism of clutching member translation on first lateral shaft thereby must on clutching member, apply axial substantially power.
In this type gear group, power-transfer clutch by operating with fork-shaped finder slide engaging and disengaging element on first lateral shaft, joins clutching member in the circumferential translation groove to traditionally.But this finder obviously must be avoided finishing bevel gear cuter, and finder needs the space, and this is an ancillary cost (premium) for gear cluster, and the special requirement of these finders has hindered the development of compact novel stern actuator.Should remember that gear cluster is positioned at the rear of the horizontal material of tail, and the hydrodynamics character of marine drive may have a strong impact on by the size of gear cluster, gear case, cylindrical drum etc.,
