Abstract
The utility model relates to a novel CBY-type blade curve connecting structure, which effectively solves the problems of low blade strength, short service life, high labor and material consumption and high cost. The technical scheme for solving the problems includes that the novel CBY-type blade curve connecting structure comprises blades, support lug bottom plates, support lug rib plates and a stirring shaft, the support lug bottom plates are mounted on the peripheral wall of the stirring shaft, the roots of the support lug rib plates on the support lug bottom plates are fixedly connected onto the stirring shaft, the front ends of the support lug bottom plates and the rear ends of the blades are fixedly connected together, and the connection positions of the support lug bottom plates and the blades are in curve connection. The novel CBY-type blade curve connecting structure has the advantages of novel and unique structure, high blade strength, labor and material economization and low cost.
Description
One, technical field
The utility model relates to agitator, particularly a kind of novel C BY blade curved surface syndeton.
Two, background technology
The agitator kind and the specification that are applied to industries such as metallurgy, chemical industry, medicine at present are a lot, and wherein axial flow type stirrer is most widely used general.Big-and-middle-sized agitator is generally bigger because of its oar footpath, in order to install and convenient maintenance and replacement, mainly adopts bolt connecting mode.
The blade structure of bolt connecting mode generally has two kinds: a kind of is that journal stirrup connects, and this mode need flatten blade and journal stirrup coupling part, and maximum torsional forces is being born in the coupling part, and flattening the back influences blade intensity, then must adopt to add steel plate making blade; Another kind then is to adopt the flange connection, and blade is suppressed a back and a flanged plate welding with mold, also welds adaptive flange on the axle accordingly, and two flanges adopt bolt to connect.More than compare on the blade structure of these two kinds of agitators, the former needs the thickness of slab of blade to increase, though the latter does not increase the blade thickness of slab, but processing of the material of base plate and flanged plate, flange and welding have increased cost, so the syndeton of blade how to develop a kind of labor and material saving and journal stirrup becomes the problem that needs solution and study.
Three, summary of the invention
At above-mentioned situation, for overcoming the prior art defective, the purpose of the utility model just provides a kind of novel C BY blade curved surface syndeton, and it is low effectively to solve blade intensity, and the life-span is short, the expense of taking a lot of work material, the problem that cost is high.
The technical scheme that the utility model solves is, comprise blade, journal stirrup base plate, journal stirrup gusset and shaft, the journal stirrup base plate is housed on the shaft perisporium, the root of the journal stirrup gusset on the journal stirrup base plate is fixedly connected on the shaft, the front end of journal stirrup base plate and the rear end of blade are fixed together, and the junction of journal stirrup base plate and blade is that curved surface is connected.
The utility model novel structure uniqueness, blade intensity height, labor and material saving, cost is low.
Four, description of drawings
Fig. 1 is a structural front view of the present utility model.
Fig. 2 is that the A-A of the utility model Fig. 1 is to cutaway view.
Fig. 3 is the cutaway view of existing product.
Five, the specific embodiment
Below in conjunction with accompanying drawing the specific embodiment of the present utility model is elaborated.
By Fig. 1-shown in Figure 2, structure of the present utility model is, comprise blade, journal stirrup base plate, journal stirrup gusset and shaft, on shaft 5 perisporiums journal stirrup base plate 2 is housed, the root of the journal stirrup gusset 3 on the journal stirrup base plate is fixedly connected on the shaft, the rear end of the front end of journal stirrup base plate and blade 1 is fixed together, and the junction of journal stirrup base plate and blade is that curved surface is connected.
In order to guarantee result of use, the rear end of said blade 1 is connected with the journal stirrup base plate through connecting bolt 4; Said blade 1 is the uniform pitch structure, and each section is curved surface, and blade is at vicissitudinous angle and width vertically; Said journal stirrup base plate 2 is the curved surface shape, and its amount of curvature is identical with the amount of curvature of blade rear end.
The utility model is by blade, the journal stirrup base plate, the journal stirrup gusset, connecting bolt and shaft are formed, for guaranteeing whipping performance, blade is still by former designing requirement compacting, blade and journal stirrup base plate contact-making surface are plane (as shown in Figure 3) in former design, also contact-making surface to be done to flatten after the blade compacting and handle, now for improving its intensity, curved surface after the blade compacting no longer flattens, but change the journal stirrup base plate into curved surface by the primary plane design, and it is identical with blade contact-making surface curvature, fit tightly, when making the journal stirrup base plate, utilize a compression moulding of blade mold, consistent with the moulding of blade contact-making surface to guarantee it, i.e. journal stirrup base plate curved surface angle variation is identical with propeller shank, fits fully, journal stirrup base plate and journal stirrup gusset welding then, the control welding deformation amount guarantees that postwelding journal stirrup base plate still can be consistent with propeller shank curvature, and journal stirrup base plate and the journal stirrup gusset with postwelding mills out intersection and shaft welding again.Blade and journal stirrup base plate are fixed by connecting bolt.
The utility model basic principle is as follows: according to theory of mechanics of materials knowledge as can be known, the sheet material of identical material, thickness, width, module of anti-bending section is the module of anti-bending section on plane greater than its cross section when its cross section is arc, know according to σ=M/Wz, under the condition identical at material, that allowable stress is identical, module of anti-bending section is big more, and then its load that can bear is big more.Therefore, we can become blade along the curved surface of propeller shank with the syndeton of journal stirrup base plate according to this theory and are connected.No longer flatten processing after the blade compression moulding, but the journal stirrup base plate also is pressed into identical cambered surface, so just improve the bearing capacity of its coupling part.Under the situation of same load, just can select the thin material of wall thickness to suppress blade, thereby reach the requirement of labor and material saving.
The utility model is by the change to blade and journal stirrup base plate syndeton, not only because of blade, the minimizing of journal stirrup baseboard material thickness reduces production costs 20～30%, also guaranteeing former mixing effect, in the time of working strength, reduced the running resistance of blade, reduced the energy consumption of agitator, the utility model is a kind of simple in structure, be easy to dismounting, the processing and fabricating amount is less, the syndeton of cost-effective again blade and journal stirrup, can be at metallurgy, chemical industry, promote the use of on the every profession and trade agitators such as medicine, especially at high-power, the axial flow type stirrer in big oar footpath, the economical with materials cost is realized good economic benefit largely.
