Abstract
The utility model relates to a thruster propeller, which mainly comprises a plurality of blades and a hub, wherein the outer wall of the hub is uniformly provided with the blades, the fixed ends of the blades are connected with the hub, the connecting part between the fixedend of each blade and the hub is in smooth transition, each blade adopts a large knife type blade, the thickness of each blade is gradually reduced from the back blade surface to the front blade angle, an inner hole of the hub is a conical hole, the position, corresponding to the center of the connecting portion of one blade and the hub, of the wall of the inner hole is provided with a key groove, the bottom of each key groove is parallel with the axis of the inner hole of the hub, and the blades and the hub are integrally formed. The thruster propeller has the beneficial effects that when the thruster propeller is used in ship machinery and mine machinery, the center hole of the hub is connected with a shaft in a key tightening and cone tightening way, so the stress on the main body of the propeller is uniform, and the safety, reliability and stability are realized; the rotational resistance can be reduced by the shape of each blade, the energy source is saved, and the loss is reduced.
Description
Technical field
The utility model relates to a kind of mechanical equipment accessory, especially relates to a kind of screw propeller.
Background technology
At present, existing screw propeller on market, it mainly comprises blade and leaf hub, the radical function of screw propeller is that the mechanical energy that marine main engine mining machinery main frame sends is converted into kinetic energy, cause blade and the leaf hub of screw propeller to bear larger application force, existing screw propeller is due to reasons such as the structures of material, blade plan form and leaf hub, can not well reduce the application force that screw propeller main body is born, long-time use screw propeller main body is easy to impaired, often changes the very large economical burden that screw propeller main body increases; And the structure of existing screw propeller main body can not the high efficiency mechanical energy that marine main engine mining machinery main frame is sent be converted into kinetic energy, cause very large degradation of energy, waste energy, in addition, the structure that screw propeller main body is connected with rotating shaft is single, stability and poor reliability.
Summary of the invention
The purpose of this utility model is to provide and a kind ofly saves the energy, reduces the wastage, reduces costs and safe and reliable stable screw propeller.
A kind of propeller screw oar, it mainly comprises blade and leaf hub, uniform several blades of its middle period hub outer wall, blade fixed end is connected with leaf hub, the position rounding off that both are connected, described blade is machete type blade, the thickness of blade is contended gradual change from rear edge face to front edge little; Described leaf hub endoporus is taper hole, and be connected with the leaf hub center of one end of the corresponding blade of inner hole wall is provided with a keyway, and the bottom of described keyway is parallel with the axis of leaf hub endoporus, and described blade and leaf hub are integrated.
When use, due to the shape of blade, make after screw propeller main body is connected with rotating shaft, can transfixion in different angles at the each blade of quiescence, when there being air-flow to blow over, by the effect of power, the page rotates along with flowing of air, makes screw propeller obtain momentum, saves the energy.
Compared with the prior art, the beneficial effects of the utility model are: ship machinery and mining machinery are in the time that use is of the present invention, leaf hub centre hole is connected with axle and adopts the fastening and fastening form of the conical surface of key, make screw propeller main body stressed evenly, safe and reliable stable, the shape of blade can reduce the resistance of rotation, saves the energy, reduces the wastage.
accompanying drawing explanationfig. 1 is that master of the present utility model looks simplified schematic diagram.
Fig. 2 is side-looking section simplified schematic diagram of the present utility model.
the specific embodimentlook in the side-looking section simplified schematic diagram of the present utility model shown in simplified schematic diagram and Fig. 2 the master of the present utility model shown in Fig. 1, uniform three blades 2 of its middle period hub 1 outer wall, blade fixed end is connected with leaf hub, the position rounding off that both are connected, described blade is machete type blade, the thickness of blade from rear edge face 3 to the basil 4 diminish gradually; Described leaf hub endoporus is taper hole, and be connected with the leaf hub center of one end of the corresponding blade of inner hole wall is provided with a keyway 5, and the bottom of described keyway is parallel with the axis of leaf hub endoporus, and described blade and leaf hub are integrated.
Claims (1)
1. a propeller screw oar, it mainly comprises blade and leaf hub, it is characterized in that: uniform several blades of leaf hub outer wall, blade fixed end is connected with leaf hub, the position rounding off that both are connected, described blade is machete type blade, the thickness of blade is contended gradual change from rear edge face to front edge little; Described leaf hub endoporus is taper hole, and be connected with the leaf hub center of one end of the corresponding blade of inner hole wall is provided with a keyway, and the bottom of described keyway is parallel with the axis of leaf hub endoporus, and described blade and leaf hub are integrated.
