Abstract
The utility model provides a pipe shape disk of conical profile marine propulsor, relates to a marine propulsor, including main shaft, support, disk of conical profile and circular -tube -shaped outer shell. The main shaft passes through the bearing and installs on the support. The disk of conical profile includes preceding end disc, rear end ring and the even the same blade of several distribution. The section of blade is the wing section. On the end disc was all installed in the front to the root of all blades, the point portion of all blades all installed on the ring of rear end. The rectangular contained angle to the extension line backward with the main shaft of exhibition of blade is the acute angle. The preceding end disc of disk of conical profile links to each other with the main shaft. The main shaft is in the place ahead of disk of conical profile, power from main shaft input. The disk of conical profile is in inside the circular -tube -shaped outer shell completely. Power passes through the main shaft and drives toper rotating impeller, with extruding in the water inspiration circular -tube -shaped outer shell in the place ahead then from circular -tube -shaped outer shell's rear. The utility model discloses propeller efficiency is higher, compares with traditional screw propeller, and the external diameter wanted much little when thrust was the same, and the resistance is less.
Description
Technical field
A kind of tubular disc of conical profile marine propeller, relates to a kind of marine propeller, particularly relates to a kind of tubular marine propeller.
Background technology
Traditional marine propeller is screw propeller, and its blade is substantially at the rotation with in surface vertical with rotating shaft, and external diameter is comparatively large, and resistance is comparatively large, and especially pressure drag and form resistance are comparatively large, and because of sectional area comparatively large, the horizontal space needed for installation is larger.
Summary of the invention
The object of the invention is to overcome above-mentioned the deficiencies in the prior art, the tubular disc of conical profile marine propeller providing a kind of resistance less.
Technical scheme of the present invention is: a kind of tubular disc of conical profile marine propeller, comprises main shaft, support, disc of conical profile and tubular shell.Main shaft is rack-mount by bearing, and support is connected with tubular shell.Main shaft is arranged between two parties in the diametric(al) of tubular shell.Main shaft is consistent with the opening direction of tubular shell.Disc of conical profile comprises front end disk, rear end annulus and several identical blade be evenly distributed.The section of blade is aerofoil profile.Vaned root is all arranged on the disk of front end, and vaned tip is all arranged on the annulus of rear end.The angle of the length direction of blade and the extended line backward of main shaft is acute angle.The front end disk of disc of conical profile is connected with main shaft.Main shaft is in the front of disc of conical profile, and power inputs from main shaft.Disc of conical profile is in tubular enclosure completely.
For raising the efficiency, the internal diameter of tubular shell is a bit larger tham the external diameter of the rear end annulus of disc of conical profile.The difference of the external diameter of the internal diameter of tubular shell and the rear end annulus of disc of conical profile is between 1 ~ 5mm.The angle of the length direction of blade and the extended line backward of main shaft is not more than 60 °.Support adopts tripod.
A kind of tubular disc of conical profile of the present invention marine propeller is work like this, and power drives disc of conical profile to rotate by main shaft, and then blade is extruded in the water inspiration tubular shell in front from the rear of tubular shell.Because main shaft is in front, current can not be subject to the resistance of engine installation by the process that disc of conical profile accelerates to flow backward, and due to the existence of tubular shell, therefore this propeller efficiency is higher.
The advantage of a kind of tubular of the present invention disc of conical profile marine propeller is: compared with traditional propeller, when thrust is identical, the angle of rake external diameter of the present invention is much smaller, and efficiency is similar with traditional propelling unit; When the most outstanding advantage of propelling unit of the present invention is high speed, resistance is less.
Accompanying drawing explanation
Fig. 1 is the schematic diagram of a kind of tubular disc of conical profile of the present invention marine propeller, and Fig. 2 is the birds-eye view of Fig. 1.In figure: 1 is main shaft, 2 is support, and 3 is disc of conical profile, and 31 is front end disk, and 32 is blade, and 33 is rear end annulus, and 4 is tubular shell, and 5 represent streamline, and in Fig. 1, the hollow arrow on right side represents the angle of rake working direction of the present invention.
Detailed description of the invention
Below in conjunction with accompanying drawing, the present invention is illustrated: with reference to accompanying drawing, a kind of tubular disc of conical profile marine propeller, comprises main shaft 1, support 2, disc of conical profile 3 and tubular shell 4.Main shaft 1 is arranged on support 2 by bearing, and support 2 is connected with tubular shell 4.Main shaft 1 is arranged between two parties in the diametric(al) of tubular shell 4.Main shaft 1 is consistent with the opening direction of tubular shell 4.Disc of conical profile 3 comprises front end disk 31, rear end annulus 33 and several identical blade 32 be evenly distributed.The section of blade 32 is aerofoil profiles.The root of all blades 32 is all arranged on front end disk 31, and the tip of all blades 32 is all arranged on rear end annulus 33.The angle of the length direction of blade 32 and the extended line backward of main shaft 1 is 50 °.The front end disk 31 of disc of conical profile 3 is connected with main shaft 1.Main shaft 1 is in the front of disc of conical profile 3, and power inputs from main shaft 1.It is inner that disc of conical profile 3 is in tubular shell 4 completely.The difference of the external diameter of the internal diameter of tubular shell 4 and the rear end annulus 33 of disc of conical profile 3 is 2mm.Support 2 adopts tripod.
This propelling unit is work like this: power drives disc of conical profile 3 to rotate by main shaft 1, and then blade 32 is extruded in the water inspiration tubular shell 4 in front from the rear of tubular shell 4.Because main shaft 1 is in front, current can not be subject to the resistance of engine installation by the process that disc of conical profile 3 accelerates to flow backward, and due to the existence of tubular shell, therefore this propeller efficiency is higher.
