Abstract
The utility model relates to a contrary-turning paddle all-around traverse propeller which is an improvement on the Schttel steering paddle all-around turning propeller device (SRP). The utility model adopts a bevel gear group with special structure to change a single paddle into a contrary-turning paddle in order to obtain the purpose of improving propulsion efficiency and saving energy.
Description
The utility model belongs to marine propulsion.
All-rotation thrust unit claims Z type propelling unit again, also is the rudder oar.Compare with traditional driving engine-axle-propeller propulsion system, have unit and arrange compact; Maneuvering performance is good; Installation and maintenance are advantage easily.
The seventies is mainly used in various dragging (pushing away) wheel, and the eighties expands various repair ships, high-speed boat, fishing boat and ocean engineering drilling ship etc. gradually to.
Manufacturer also develops into West Europe, Japanese companies by initial West Germany Xiao Teer (Schottel) fewer companies.
Fig. 1, Xiao Erte rudder oar apparatus structure scheme drawing;
Fig. 2, to changeing oar all-rotation thrust unit pattern I structural representation;
Fig. 3, to changeing oar all-rotation thrust unit pattern II structural representation.
Its typical structure be Xiao Teer rudder oar device (SRP) as shown in Figure 1.
The power of driving engine through last bevel gear set (9), becomes the power of vertical axis (10) by axle (1), and the following bevel gear set (4) of lower end becomes the propulsive effort of screw propeller (6) with the power of vertical axis, promotes boats and ships and advances.The power of coming about drives outer sleeve (3) by axle (2) by bevel gear set (8), rotates together with baffle (5).Propeller thrust plays the effect of rudder power simultaneously.Because 180 ° rotation about outer sleeve (3) can vertically be done together with baffle (5), meaning promptly are equivalent to the thrust of screw propeller hull is formed the effect of 360 ° of any directions, so can realize that reversing, thruster, cast etc. are motor-driven arbitrarily.
As required, can add conduit (7), to increase bitt thrust at screw propeller.
This device is the practical history of existing three more than ten years abroad, uses quite general in recent years.China mainly was by buying the complete equipment of foreign country, building the full circle swinging sea-going tug over past ten years.People appreciate the manoevreability that it is superior, and widely used enthusiasm also has the trend that further increases.But, because the baffle yardstick of device proper is bigger, two mechanically operated wastes of power of bevel gear set in addition, it is compared with traditional propulsion system, on propulsion coefficient, there is not advantage, therefore, consider that its application has been subjected to certain restriction again from energy-conservation angle.
The purpose of this utility model is to create a kind of structure of new following bevel gear set, become single-blade and advance to advancing changeing oar, thereby the raising propulsion coefficient reaches the effect of energy savings.
The utility model at the following structure more than the bevel gear set and Xiao Teer rudder oar device mutually roughly the same, mainly in baffle, the following bevel gear set that is provided with special construction changes the shaft mode of screw propeller, and Fig. 2 and Fig. 3 represent its two versions respectively: pattern I and pattern II.
The pattern I be to one bring out the axle crp propulsion device form, its structural principle is as follows:
Vertical axis (10) upper part is identical with Xiao Teer rudder oar device, and by dynamical axis (1) steering shaft (2), last bevel gear set (9) and (8) and outer sleeve (3) are formed.
The bevel gear set of vertical axis (10) lower end, formed by finishing bevel gear cuter (11,12,15), the finishing bevel gear cuter (11) that is fixed on vertical axis drives finishing bevel gear cuter (12,15) rotation relatively simultaneously, finishing bevel gear cuter (15) is connected with hollow shaft (20), be located on the bearing (16,17), (16) be thrust baring, dress front propeller (18) on the axle, finishing bevel gear cuter (12) links to each other with a solid axle (14), go up rotation at bearing (13,21), (13) be thrust baring, (21) are plain bearing, axle head dress after screw (19).When the power of driving engine by axle (1), when last conical tooth shaft group (9) became the power of vertical axis, two finishing bevel gear cuters (12) (15) of its lower end formed relative rotation together with the front and back screw propeller that is connected, this is the crp propulsion device.Its method of coming about is identical with Xiao Teer rudder oar device.The power of promptly coming about drives outer sleeve (3) by axle (2) by conical tooth shaft group (8), and respectively rotation of 180 ° about can doing together with baffle realizes required various motor-driven.
The pattern II is the crp propulsion device form to the two ends shaft, and its structural principle is as follows:
Vertical axis (10) upper part is identical with Xiao Teer rudder oar device, by dynamical axis (1), steering shaft (2), go up bevel gear set (8) and (9) and reach outer sleeve (3) and form.
The bevel gear set of vertical axis (10) lower end, by finishing bevel gear cuter (23,24,33) form, be fixed on the finishing bevel gear cuter (23) of vertical axis, drive finishing bevel gear cuter (24 simultaneously, 33) rotation relatively, the axle (27 that is connected with it, 30) be located in bearing (25 respectively, 26) and bearing (31,32) on, wherein (25) are thrust baring with (32), axle (27,30) relatively stretch out to two ends, the termination is adorned screw propeller respectively, engine power is through axle (1), bevel gear set (9), and vertical axis (10), finishing bevel gear cuter (23) (24) (33), form axle (27) (30) at last and the relative rotation of the screw propeller on it that is connected, promptly form a pair of propeller with respect to rotation.Its method of coming about is identical with the pattern I.
As required, outside the oar of pattern I and II, also conduit can be installed.
The utility model is compared with general full circle swinging propeller, and outstanding advantage is arranged.
(1) under identical power, thrust is shared by two oars, and then the parts yardstick on each prop shaft can correspondingly reduce, thereby makes also corresponding the diminishing of yardstick (diameter) of baffle.Again since two oars to changeing, the energy that back oar can partially recycled bow oar wake field, so the total propulsion coefficient of screw propeller can be greatly improved, according to calculating, in the ordinary course of things, than the efficient raising about 10% of common single screw all-direction propeller.
(2) under equal-wattage, the diameter of two oar optimum efficiencies is little than single-blade situation, this to the shallow water river course with regard to advantageous particularly.
(3) the front and back oar of pattern II is symmetrical, so rudder moment is less, and under the situation of emergent manual steering, this is comparatively favourable.
The designer has finished the design effort to commentaries on classics oar all-rotation thrust unit that is complementary with 40-60 horsepower main frame, is about to send the factory process manufacturing, just can load debugging onto ship within the next few days.
