Description
Technical field
The utility model relates to a kind of lubricating system, relates in particular to the lubricating system that a kind of large power, electrically pushes away rudder oar.
Background technology
It is a kind of Z-shaped power transmission propelling unit that large power, electrically pushes away rudder oar, and common rudder oar body comprises upper gear box, the gear case of coming about, rudder angle ultramagnifier, hydraulic oil motor, come about pipe, power drive shaft, well case, lower tooth roller box, the compositions such as screw propeller and conduit.The combination unit that common a whole set of rudder oar engine installation is comprised of highly elastic shaft coupling, lubrication box, lubricating pump group, Hydraulic Pump group, hydraulic reservoir, cooling vessel, the maneuvering system of coming about and rudder oar device body etc.
Rudder oar Powerpush Unit radical function is that transmission of power motor (primary mover) being sent by the two pairs of spiral bevels in high-elastic plunging joint and the upper and lower gear case of rudder oar produces thrust to screw propeller; Can control the lower tooth roller box with screw propeller by electrohydraulic control system, unrestrictedly revolution to the left or to the right, so whole thrusts of screw propeller arbitrarily can act on any direction, thereby obtains the optimized matching of propelling and thrust direction simultaneously.No matter large or small rudder oar device is similar on surface structure both at home and abroad.Puzzlement rudder oar device is how to reduce heating, raising mechanical efficiency to the subject matter of high-power future development.Being generally used for its upper and lower two pairs of right angle spiral bevels of powerdriven rudder oar is immersed in lubricating oil and is lubricated, although guaranteed like this gear lubrication, but because gear, bearing rub, stir the heat that lubricating oil produces in transmission, make oil temperature fast rise, high-power rudder paddle is because cal val is large, heat radiation difficulty, and situation is even more serious.How to reduce machinery heating, how fast heat extraction is a gordian technique of high-power rudder paddle design.Traditional design adopts cooling vessel to carry out cooling, reduction oil temperature, and its shortcoming is to increase cooling system.Due to increase cooling system, improved on the one hand the power drain of rudder oar complete machine, the mechanical efficiency of equipment is low, lack competitiveness in market, on the other hand because the functional reliability of cooling system is most important to rudder oar, therefore design, the production requirement of cooling system are all higher, increase the holistic cost that cooling system has just increased rudder oar.
Therefore, research and design is a kind of can realize the hydronic succinct failure-free high-power rudder paddle lubricating system of oneself, is a problem being significant.
Utility model content
The purpose of this utility model is: the lubricating system for the high-power rudder paddle of current existence need to be by being equipped with separately cooling system, complex structure not only, but also need to consume the energy, and affect the problems such as work efficiency, provide a kind of new large power, electrically to push away the lubricating system of rudder oar group.
The purpose of this utility model is achieved in that a kind of large power, electrically pushes away the lubricating system of rudder oar group, comprise upper gear box, well case, the pipe of coming about, middle vertical shaft and lower tooth roller box, middle vertical shaft two ends are provided with angular wheel shaft, it is characterized in that: in lubricating system, also comprise filter and motor-driven lubricating pump, described upper gear box top is also provided with compensation fuel tank, and compensation fuel tank is by the internal communication of overflow pipe and upper gear box; In described well case, be provided with internal layer oil pocket and outer oil pocket, between ectonexine oil pocket, at least by a hole, link up; Described middle vertical shaft and the axle center of two ends angular wheel shaft are provided with the oil return oil duct of perforation; The described pipe of coming about is provided with force feed screw rod with the middle vertical shaft of well case internal layer oil pocket intersection, and coming about between pipe and middle vertical shaft is interlayer oil duct;
The circulating path of lubricating oil is: when middle vertical shaft rotating, the lubricating oil of well case internal layer oil pocket is pressed into interlayer oil duct by force feed screw rod, entering lower tooth roller box is lubricated the active flank of each gear, then the oil return oil duct by middle vertical shaft and two ends angular wheel shaft returns to upper gear box the active flank of each gear is lubricated, then enters the internal layer oil pocket of well case; After the lubricating oil of internal layer oil pocket is linked up by the hole of ectonexine oil pocket, the lubricating oil that enters outer oil pocket is sent into compensation fuel tank by motor-driven lubricating pump through filter, and compensation fuel tank is upper gear box make-up oil by overflow pipe.
In the utility model: also comprise temperature sensor and flow counter in lubricating system, temperature sensor and flow counter are located on the pipeline between filter and compensation fuel tank.
In the utility model: link up by 2-10 well-distributed hole between described well case ectonexine oil pocket.
In the utility model: the angular wheel shaft of middle vertical shaft one end is driven by the input shaft of driven by motor, the angular wheel shaft of the middle vertical shaft other end drives oar axle.
The utility model has the advantage of: what by lubricating oil in upper and lower gear case, form circulates, improved the cooling effectiveness that lubricating oil and flowing seawater carry out interchange of heat, make the lubricating oil in rudder oar just can reach heat balance when lower oil temperature, do not need additional cooling system, not only energy-conservation but also reliable, obviously reduce energy consumption, guaranteed the use temperature rise of system, guaranteed the reliability service of rudder oar system.The cold lubricating oil that the hot lubricating oil on rudder oar top is pressed into the cold lubricating oil in bottom and promotes bottom due to spiral shell force feed screw rod enters upper gear box, has improved cooling performance in circulation.
Because lubricating pump is extracted into compensation fuel tank by the lubricating oil in the outer oil pocket of well case, can reduce the height of lubricating oil liquid level in upper gear box, make the split bearing in upper gear box and cog to expose lubricating oil, avoided the heating of oil that stirs of gear and bearing, cal val while having greatly reduced working gear, meanwhile, the lubricating oil being pumped the again overflow pipe of lubricating oil by compensation fuel tank sprays and cogs on the flank of tooth, has fully guaranteed the good lubrication of gear active flank.This operation scheme can make rudder oar cal val cut down 3/5.In addition, the utility model has omitted independently cooling system, makes structure compacter.
