Abstract
The utility model relates to a power propelling appliance of a small waterplane area twin-hull ship, which comprises propellers and a power device. The appliance is characterized in that the propellers are connected to a tail shaft connected with a thrust bearing, the thrust bearing is connected with an intermediate shaft, and the intermediate shaft is connected with the power device. In the appliance, the thrust bearing mounted behind is arranged between the tail shaft and the intermediate shaft, length of the tail shaft is then reduced, and simultaneously, the intermediate shaft only rotates and transmits torque without bearing axial force, thereby simplifying bearing of the intermediate shaft and a coupling, decreasing shafting vibration, lowering noise and reducing bearing wear.
Description
Technical field
The utility model relates to a kind of small waterplane area twin hull ship (SWATH), especially relates to a kind of Powerpush Unit of small waterplane area twin hull ship (SWATH).
Background technology
Small waterplane area twin hull ship (SWATH) is high-tech, high added value, high-performance ship.The rough water quality of this class ship is better than all kinds of boats and ships of conventional displacement, and the rate of sailing height, seasick rate are low, are described as " ship of sea legs ", " ship that wait in full sea ".Under high sea condition, rapidity is good, on the wave stall little, manoeuvrable, but cast are easily by the watchman's wooden clapper operation; Deck spaciousness, cabin are easy to arrange, and working space is big; Viability is strong, and margin of safety is big; Underwater radiation noise is little and be easy to control, helps satisfying the requirement of calm type flat-bed.These good characteristics of small waterplane area twin hull ship (SWATH) have determined that its application in the world is day by day extensive, and no matter in military domain or at civil area, small waterplane area twin hull ship (SWATH) has all been brought into play its uniqueness and irreplaceable vital function.
The structures shape of small waterplane area twin hull ship (SWATH) its Powerpush Unit be installed in the submerged body usually, and Powerpush Unit usually adopts following two kinds of versions:
A. behind the high speed diesel engine reducing gearbox is set, thrust baring is arranged in the gear case, and connects tween drive shaft and tailing axle by coupler, the rear end connecting bolt slurry of tailing axle.
B. low speed diesel engine is not established reducing gearbox, and thrust baring is arranged between tween drive shaft and the diesel engine, and tween drive shaft connects tailing axle by coupler, the rear end connecting bolt slurry of tailing axle.
In the Powerpush Unit of small waterplane area twin hull ship (SWATH), the length of tween drive shaft is longer, and thrust baring is arranged near the diesel oil pusher side, and tween drive shaft had both turned round transfer torque when work, and tween drive shaft is subjected to the compression extruding of axial force when boats and ships advance; When boats and ships are moveed backward, tween drive shaft is subjected to the stretching of axial force again, the shaft coupling screw of coupler is stretched simultaneously, this axial compressive force and tensile force make the stressed complexity of tween drive shaft, and be easy to generate unsettled harmful displacement, and make axle system produce vibration, thus bigger noise produced, and the aggravation wear-out of a bearing.
The utility model content
The applicant has carried out research and has improved at above-mentioned problem, and a kind of Powerpush Unit of small waterplane area twin hull ship (SWATH) is provided, and simplifies the stressed of tween drive shaft and coupler, reduces shafting vibration, reduces noise, and alleviates wear-out of a bearing.
In order to solve the problems of the technologies described above, the utility model adopts following technical scheme:
A kind of Powerpush Unit of small waterplane area twin hull ship (SWATH) comprises screw propeller and engine installation, and described screw propeller connects tailing axle, and tailing axle connects thrust baring, and thrust baring connects tween drive shaft, and tween drive shaft connects described engine installation.
Further:
Described tween drive shaft is provided with two middle bearings.
Described engine installation is a propulsion electric machine.
Technique effect of the present utility model is:
The Powerpush Unit of the disclosed a kind of small waterplane area twin hull ship (SWATH) of the utility model, with the thrust baring postposition, be arranged between tailing axle and the tween drive shaft, can reduce the length of tailing axle, tween drive shaft only be turned round and transfer torque, no longer bear axial force, thereby simplify the stressed of tween drive shaft and coupler, reduce shafting vibration, reduce noise, and alleviate wear-out of a bearing.
Description of drawings
Fig. 1 is a structural representation of the present utility model.
The specific embodiment
Below in conjunction with accompanying drawing the specific embodiment of the present utility model is described in further detail.
As shown in Figure 1, the utility model is arranged on the rear portion of the submerged body 10 of small waterplane area twin hull ship (SWATH), it comprises screw propeller 1 and engine installation 5, and screw propeller 1 connects tailing axle 2, and tailing axle 2 connects thrust baring 3 by coupler 7, thrust baring 3 connects tween drive shaft 4 by coupler 8, tween drive shaft 4 connects engine installation 5 by coupler 9, and tween drive shaft 4 is provided with two middle bearings 6, in the present embodiment, engine installation 5 adopts propulsion electric machine, and coupler 7, coupler 8 and coupler 9 all adopt high-elastic coupler.Thrust baring 3 is arranged between tailing axle 2 and the tween drive shaft 4, thrust baring 3 postposition compared with prior art, can reduce the length of tailing axle 2 like this, tween drive shaft 4 is only turned round and transfer torque, no longer bear axial force, thereby simplify the stressed of tween drive shaft and coupler, simultaneously thrust baring 3 is arranged in the aft peak at submerged body 10 rear portions, the volume of compartment that the thrust baring postposition is reserved can be provided with fresh water tank 11, makes full use of the space in the submerged body.
