Description
Technical field
This utility model is related to a kind of gear-box, more particularly to a kind of driveshaft section of lightweight heavy duty marine gearbox
Part, belongs to the actuating device field of ship auxiliary power output.
Background technology
Mesh prior art marine gearbox typically has two kinds of structure types of outer support and inner support, traditional external supporting structure
The driving gear of marine gearbox on casing, causes axial dimension than larger, driving gear typically using two bearings
Assembly and disassembly maintenance difficult.Traditional inner supporting structure marine gearbox driving gear adopts integrative-structure, friction plate with clutch base
It is smaller, power limited is transmitted, and because driving gear is generally required by needle bearing or sliding shaft sleeve come empty set in input
On axle or power transmission shaft, the axial force in working gear must have needle roller thrust or thrust slide bearing to bear, complex structure, easily
Damage that part is more, simultaneously because the needs in adjustment gap, input shaft and power transmission shaft typically all can before and after it is fixed, cause maintenance typically all to need
Integrally to hang out, keep in repair very difficult.
Utility model content
This utility model mainly solves the deficiencies in the prior art, there is provided one kind has clutch function, and structure is tight
Gather, simple to operate, small volume is lightweight, reliability is high, transmission efficiency, gear ratio excursion is big, good looking appearance, maintenance
A kind of convenient power transmission shaft part of lightweight heavy duty marine gearbox.
What above-mentioned technical problem of the present utility model was mainly addressed by following technical proposals：
A kind of power transmission shaft part of lightweight heavy duty marine gearbox, including casing, in described casing power transmission shaft is provided with,
Transmission gear component is set with outside described power transmission shaft, the right-hand member of described power transmission shaft is cased with mutually being nibbled with input drive gear
Close the reversing travelling gear of transmission；
Reverse clutch component is provided between the right-hand member and reversing travelling gear of described transmission gear component, it is described
Reverse clutch component includes working piston and bearing plate, is provided with continuous distribution between described bearing plate and working piston
Friction plate and outside friction disc, the outer wall of low order end inner attrition piece is provided with one side outside friction disc, described transmission gear component
Right-hand member be provided with spring base with transmission between centers, be provided with return spring between described spring base and working piston；
Described transmission gear component includes driving gear and clutch base, and the right-hand member of described driving gear is provided with
Clutch base；
Lead to respectively between the left end and casing of described transmission gear component, between the right-hand member of reversing travelling gear and casing
Cross single-row or double-row conical bearing positioning；
Respectively by cylinder roller bearing or taper roller axle between the right-hand member and casing of described transmission gear component
Hold positioning.
Preferably, being positioned with elastic spring by hole between described bearing plate and reversing travelling gear, described work
Between piston and reversing travelling gear, working piston positioned by sealing ring respectively with transmission between centers, described spring base and transmission
Between centers is positioned respectively by circlip for shaft, and described working piston passes through elastic cylinder finger setting with reversing travelling gear.
Preferably, the right-hand member of described power transmission shaft is provided with the oil seal ring mutually closed with casing, in described power transmission shaft
Oil duct is mutually closed by vexed plug.
Transfer principle：After prime mover starts, power is input into by input coupling band driven input shaft and hot jacket on input shaft
Travelling gear is rotated, and input drive gear drives be engaged with reversing travelling gear rotation again；
When the joystick of reversal valve is in " sky " position, ahead running clutch and reverse clutch are in disengaged condition, this
Without power output, output shaft is not rotated Shi Suoyou clutches；
When the joystick of reversal valve is in " ahead running " position, ahead running clutch is combined, reverse clutch is disengaged, and power Jing is defeated
Enter shaft coupling, input shaft, input drive gear to ahead running clutch, ahead running clutch drives again driving gear and is meshed therewith
Output gear rotate, output gear drives output shaft and output shaft coupling to rotate, the now rotation direction of output shaft and input shaft phase
Instead；
When the joystick of reversal valve is in " reversing " position, reverse clutch is combined, ahead running throw-out-of clutch, and power Jing is defeated
Enter shaft coupling, input shaft, input drive gear, reversing travelling gear and reach reverse clutch, reverse clutch drives again actively
Gear and the output gear being meshed therewith are rotated, and output gear drives output shaft and output shaft coupling to rotate, now output shaft
Rotation direction it is identical with input shaft；
Advantage：Because this utility model driving gear one end is supported on casing, the other end is supported in input/power transmission shaft
Portion, it is compact conformation, small volume, lightweight；Without thrust ring or plane needle roller thrust bearing in structure, reliability is high；Input shaft
Need not fix in front end with power transmission shaft, input shaft and power transmission shaft just can be pulled down conveniently after back box lid is pulled down, keep in repair very square
Just；Casing is born and be arranged in airscrew thrust segment set side, dramatically increases casing intensity.
Therefore, the power transmission shaft part of a kind of lightweight heavy duty marine gearbox of the present utility model, compact conformation, with knot
Structure is compact, small volume, lightweight, transmission capacity is big, reliability is high, good looking appearance, cheap for manufacturing cost, easy for assembly, disassembly and maintenance.
