Description
Technical field
The present invention relates to mechanical connecting structure field, the connecting flange of propeller of particularly a kind of flange input, is applicable to the connection that output form is flange power plant and propeller cavitation.
Background technique
Flange (Flange) is the mechanical parts be bolted together by two or more component.Flange has tapped hole or unthreaded hole, bolt makes the component that are connected on flange fastening.At present, the design all standardization of common flange, seriation, but, because the mechanical device in reality is of a great variety, and all have nothing in common with each other in utilization field, so, at some special dimensions, or under particular job environment, the flange plate of said structure is just no longer applicable.
As the Authorization Notice No. Chinese invention patent " a kind of connecting flange of propeller " that is CN201680085U discloses the connecting flange of propeller of a kind of flange input, comprise flange mounting disc and 2 and enclose above mounting hole, the propeller cavitation of different size can be connected, there is certain versatility.
And for example Authorization Notice No. is that the Chinese invention patent " a kind of flange " of CN104089118A discloses and comprises bolt hole, connecting bolt, gasket seal, bolt hole described in it is the combination of oval bolt hole and radial strip hole, can carry out centering adjustment in a plurality of directions, and the scope regulated is large.
Above-mentioned two kinds of flange plate are the modal structures of current flange, so, with regard to the structure of current flange, normally be divided into standard piece flange and non-standard component flange, for standard piece flange, namely as the flange plate structure in above-mentioned patent, its Design and manufacture all standardization and seriation, uses as standard piece.For non-standard component flange, its physical dimension disunity, need according to actual machine structure and use working environment to design accordingly.
In the technical field of power transmission of propeller cavitation, due to particularity and the complexity of propeller works environment, be similar to standard piece flange in above-mentioned two pieces patent and inapplicable, reason is, in the actuating unit of propeller cavitation, flange plays the effect connecting line shaft and propeller cavitation, under propeller works state, line shaft output torque orders about propeller rotational, in propeller rotational process, suck air-flow to discharge backward again, make the thrust that propeller cavitation obtains forward, under this force environment, flange as link is subject to the effect of moment of torsion and pulling force simultaneously, adopt traditional standard part flange arrangement obviously no longer applicable, so need the special flange arrangement being designed for propeller cavitation actuating unit.
Authorization Notice No. mentioned above is that in the Chinese invention patent " a kind of connecting flange of propeller " of CN201680085U, its structure is difficult to be connected with power input shaft one end, and the centering difficulty of propeller cavitation and flange plate is larger.
Authorization Notice No. mentioned above is that in the Chinese invention patent " a kind of flange " of CN104089118A, it very easily causes bias because center line does not overlap, and is difficult to the connection of the rotary component be applied to as propeller cavitation and so on.
At present, standard piece flange can not be applicable to the connectivity problem of reason also just between flange and pto＝power take-off of propeller cavitation technical field of power transmission, reason is, in propeller cavitation technical field of power transmission, be in rotary state during propeller works, so, propeller cavitation, the coaxality of flange and pto＝power take-off three is very important, and standard piece flange is when connecting pto＝power take-off and propeller cavitation, any structure guarantee is not provided for this reason, not hard to imagine, pto＝power take-off and propeller cavitation is connected according to standard piece flange, work as propeller cavitation, when the central axis of flange and pto＝power take-off three does not overlap, exciting will be there is because revolution is uneven in propeller cavitation in rotation process, propeller cavitation is shaken, first it be, reduce the propulsive efficiency of propeller cavitation and advance precision, what is more important makes whole equipment there is serious potential safety hazard.
So, need one at present badly and can either improve propeller propulsive efficiency and advance precision, propeller cavitation can be improved again and use device security and the propeller cavitation actuating unit of reliability and the flange for this actuating unit.
