Abstract
A blade assembly of a propeller mainly comprises a plurality of blades and a hub. The blades are evenly distributed on the outer wall of the hub, fixing ends of the blades are connected with the hub with the connecting parts being in smooth transition, each blade is a broadsword-type blade, and each blade gradually turns thinner from a rear blade surface to a front blade surface; an inner hole of the hub is a taper hole, a key slot is formed in a central position of one end, where the blades are connected with the hub, of an inner hole wall, the bottom of the key slot is parallel with an axis of the inner hole of the hub, and the blades and the hub are integrally formed. The propeller has the advantages that when the propeller is used in marine machinery and mining machinery, a central hole of the hub is connected with the axis by adopting key fastening and cone fastening forms, so that a main propeller body which is evenly stressed is safe, reliable and stable; rotational resistance can be decreased by the shape of the blades, energy is saved, and loss is lowered.
Description
Technical field
The present invention relates to a kind of mechanical equipment accessory, especially relate 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 the reasons such as structure 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 object of this invention is to provide and a kind ofly save the energy, reduce the wastage, reduce costs and safe and reliable stable screw propeller.
A 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.
During use, due to the shape of blade, make after screw propeller main body is connected with rotating shaft, can transfixion in different angles at 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, beneficial effect of the present invention is: ship machinery and mining machinery are when 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 invention looks simplified schematic diagram.
Fig. 2 is side-looking section simplified schematic diagram of the present invention.
the specific embodimentthe master of the present invention shown in Fig. 1, look in the side-looking section simplified schematic diagram of the present invention shown in simplified schematic diagram and Fig. 2, 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.
