Abstract

The present invention relates to a paddle wheel type ship propeller which is composed of a central gear, middle gears, planetary gears, a planetary gear box, paddle boards, etc., wherein the central gear is kept motionless when the central gear works, and a plurality of planetary gears are homogeneously distributed round the central gear via a plurality of middle gears. When a driving gear box rotates, each of the planetary gears can revolve round the central gear and revolve round the axis of the planetary gears in a reverse direction simultaneously, and then a plurality of paddle boards fixed on output shaft ends of the planetary gears can push a ship to move forwards and backwards in a state of being perpendicular to a horizontal plane all the time. The device overcomes the defects that the efficiency of a traditional paddle wheel is low, and a screw propeller can not run at a high speed. The present invention can be particularly used in a shallow water navigation channel.

Description

Marine propulsion

The present invention relates to a kind of marine propulsion, particularly utilize planetary transmission system, make the propelling paddle board of mouth, remain the paddle wheel formula marine propulsion of plumbness at when work and horizontal surface.

Introduce according to " propulsion of ship " book chapter 1 first page " introduction " that National Defense Industry Press publishes, common marine propulsion has oar, big shield, punt-pole, sail, paddle wheel and screw propeller etc.Wherein, use at present the widest propeller plant, its advantage be simple in structure, volume is little, but can produce the cavity phenomenon when high-speed operation, seriously hinder boats and ships and develop, and also should not in shallow draft waterway, use to high speed.Another kind of traditional paddlewheel propulsion device, since its multi-disc paddle board all with radial mode radially be fixed on the paddle wheel main shaft around, bad replacing when in case paddle board damages, particularly at work, each paddle board during entry, can produce in succession and clap water successively, causes the phenomenon of water lift during water outlet again, the loss part energy is so efficient is lower.

The purpose of this invention is to provide a kind of novel paddle wheel formula marine propulsion, but it can raise the efficiency and make boats and ships energy savings also when high-speed smooth is travelled, particularly solved on the inland shallow water navigation channel, the travel problem of difficulty of boats and ships.

Introduce according to " modern mechanical transmission " handbook chapter 9 the 265th page " involute planet gear transmission " that press of Ministry of Machine-Building Industry publishes, the speedup that well-known planetary transmission system is mainly used in machine or the machinery is slowed down, and plays chronotropic action in plurality of devices such as aviation, lifting, metallurgy.Its main element has sun gear, planetary wheel and pinion carrier etc.

Technical scheme of the present invention is to adopt the novel planetary gear train assembly, and it is made up of major parts such as sun gear, intermediate gear, planetary wheel, epicyclic gear box, planetary wheel case lid and paddle boards.Comprise sun gear bolster, intermediate gear bolster, planetary wheel bolster and bearing and sealing member etc. in addition.Sun gear is fixed on the sun gear bolster.Do not rotate during work, the engagement of a plurality of planetary wheels by a plurality of intermediate gears is evenly distributed in around it, constitutes a novel planetary gear train assembly that is different from traditional planetary transmission system.The two ends of sun gear bolster, many intermediate gear bolsters and Duo Gen planetary wheel bolster all are bearing in the respective aperture of epicyclic gear box and case lid by bearing.When external force drives the rounded epicyclic gear box of shell around the rotation of sun gear bolster, just can make each planetary wheel in sun gear revolution around the reverse rotation of axial line separately, when parameters such as the wheel tooth module of planetary wheel and sun gear, angle of obliquity and the number of teeth were just the same, promptly the transmitting ratio of planet gear and sun gear was 1: 1 o'clock.Then be fixed on many a plurality of paddle boards on the planetary wheel bolster mouth, just can remain with the water surface and be vertical state entry successively, paddling, water outlet.Do not producing under the state of clapping water and water lift, the promotion boats and ships advance or retreat.Since paddle board in entry, strike, remain plumbness in the whole process of water outlet, then paddle board plate face produces pushes away water (antagonistic force of water) and remains consistently with the direction of ship's navigation, does not clap the waste of power that water, water lift etc. cause.Therefore can improve the efficient of this propelling unit, but and high-speed operation, promote the shipping high speed navigation.On many planetary wheel bolster mouths paddle board is housed all in addition, the paddle board of working in water is had at least more than 1 all the time, and continuously entry water outlet, so very steady when promoting the boats and ships forward-reverse.Because this device can be fixed on the both sides or the afterbody of boats and ships, it is low then to have overcome traditional paddlewheel propulsion plant efficiency, the defective that propeller plant can not high-speed operation.In addition, the horizontal center line axis of this marine propulsion is to be exposed on the water surface with top, having only the following paddle board of horizontal middle spindle heart line just to be immersed in the water promotes, and simultaneously several paddle board work can be arranged, therefore the diameter of this marine propulsion can be done lessly, so can use in shallow draft waterway, it is shallow to have solved cruiseway dry season in winter water level, the difficult problem that the boats and ships that use screw propeller to advance should not navigate by water.

The present invention is fixed on the initial position of sun gear on the center shaft by change, just can change the position of each planetary wheel bolster outer end paddle board and horizontal surface simultaneously.

Below in conjunction with the drawings and specific embodiments the present invention is described in further detail.
