Abstract
The utility model provides a high -power that vice supporting is joined in marriage to four thrusts has hub wheel along propeller, includes preceding vice thrust bearing, vice thrust bearing of back, preceding main thrust bearing, the main thrust bearing in back, screw, motor stator, electric motor rotor, propeller hub and shell. Main thrust bearing and the main thrust bearing in back before the installation of propeller hub both ends, vice thrust bearing and vice thrust bearing of back before electric motor rotor both ends installation. Preceding main thrust bearing and the main thrust bearing in back respectively have 12 thrust tiles, and preceding vice thrust bearing and vice thrust bearing of back respectively have 4 thrust tiles. Screw, electric motor rotor and propeller hub are integrative designs, are equipped with motor stator on the shell. The effectively contact friction of to avoid electrical rotor and stator, the vibration and the noise of reduction propeller to it has reliability and the stability of hub wheel along the propeller to improve.
Description
Technical field
The utility model relates to a kind of wheel rim propelling unit, and being specifically related to a kind of high-powerly has hub wheel edge propelling unit.
Background technology
Traditional marine propuision system comprises the indispensable device such as main frame, Propulsion Systems and screw propeller, but along with the increase of main frame single-machine capacity, volume increases thereupon, the length of Propulsion Systems also increases thereupon, its structure is also increasingly sophisticated, consequently leads to cabin space availability ratio low, energy transfer process loss increases, the defects such as transmission efficiency reduction.Hub wheel edge propulsion system is had to be propose in recent years and a kind of brand-new Ship propulsion method developed, it by motor and propelling unit integrated, effectively can reduce the cabin space that propulsion system takies, improve the propulsion coefficient of boats and ships, decrease vibration and noise, the disguise on naval vessel can well be ensured.The design that the wheel rim of current appearance advances can be divided into two kinds according to the distribution of thrust baring, and one is that thrust baring is arranged on propeller hub two ends, and another kind is wheel rim two ends thrust baring being arranged on screw propeller outer rim, has some shortcomings separately.After the thrust baring of the first design runs for a long time and produces wearing and tearing, endplay increases, screw propeller is when unbalance stress, skew can be there is or tilt in propeller hub one end, one end that screw propeller connects wheel rim laterally will produce larger skew or inclination, may cause coming in contact friction between rotor and stator, be difficult to ensure stability and the reliability of screw propeller under motor-driven navigation or bad working environments.The thrust baring of the second design, when bearing same thrust with the first thrust baring, the friction power loss of generation is larger.
Summary of the invention
The purpose of this utility model is to overcome above-mentioned deficiency, and what provide a kind of four thrusts to join secondary supporting has hub wheel edge propelling unit, to improve the angle of rake reliability and stability of wheel rim.
The purpose of this utility model is achieved in that and comprises front secondary thrust baring, rear secondary thrust baring, front main thrust bearings, rear main thrust bearings, screw propeller, motor stator, rotor, propeller hub and shell.Front main thrust bearings and rear main thrust bearings are installed in propeller hub two ends, secondary thrust baring and rear secondary thrust baring before rotor two ends are installed.Front main thrust bearings and rear main thrust bearings respectively have 12 pieces of thrust bearing shoe valves, and front secondary thrust baring and rear secondary thrust baring respectively have 4 pieces of thrust bearing shoe valves.Screw propeller, rotor and propeller hub are Integral designs, and shell is equipped with motor stator.
Compared with prior art, the beneficial effects of the utility model are: be separately installed with a set of main thrust bearings in the both ends of the surface of propeller hub, the thrust produced during to carry screw propeller forward and backward, is provided with the secondary thrust baring of two covers in the wheel rim both ends of the surface of screw propeller outer rim simultaneously.Main thrust bearings is run for a long time and is produced the tendency that wearing and tearing after screw has lateral excursion or inclination, now the secondary thrust baring of two covers plays a role, namely producing thrust stops screw propeller to connect one end larger lateral excursion of generation or the inclination of wheel rim, effectively avoid the contact friction of rotor and stator, reduce angle of rake vibration & noise, thus raising there are the angle of rake reliability and stability of hub wheel edge.

Detailed description of the invention
As shown in Figure 1, the utility model comprises front secondary thrust baring 1, rear secondary thrust baring 2, front main thrust bearings 3, rear main thrust bearings 4, screw propeller 5, motor stator 6, rotor 7, propeller hub 8 and shell 9.Front secondary thrust baring 1 and rear secondary thrust baring 2 are arranged on the both sides of rotor 7.Front main thrust bearings 3 and rear main thrust bearings 4 are separately fixed at the both ends of the surface of propeller hub 8.Front main thrust bearings and rear main thrust bearings respectively have 12 pieces of thrust bearing shoe valves, and front secondary thrust baring and rear secondary thrust baring respectively have 4 pieces of thrust bearing shoe valves.Screw propeller 5, rotor 6 and propeller hub 8 are Integral designs, shell 9 are equipped with motor stator 6.
After electrical power, the rotor 7 being placed in magnetic field can start to move in a circle, and screw propeller 5 and propeller hub 8 rotate thereupon, and three has identical cireular frequency, propelling unit work.During normal work, front main thrust bearings 3 and rear main thrust bearings 4 bear angle of rake whole thrust, running into severe sea condition, or screw propeller 5 be subject to comparatively large unbalance power and run-off the straight time, front secondary thrust baring 1 and rear secondary thrust baring 2 bear the thrust of part, and stop screw propeller 5 to tilt further, avoid motor stator 6 and rotor 7 to come in contact friction.
