Abstract
The utility model belongs to the blower technique, and particularly relates to a rotor of a Roots blower, which comprises a shaft sleeve part (3) fitted with a rotation shaft (1), and a rotary vane part (2). The rotary vane part (2) is in a shape of uniform radial radiation; the shaft sleeve part (3) and the rotary vane part (2) are made into a whole after forming material is produced by a pultrude process and then cut. The rotor has the advantages that the shaft sleeve part (3) and the rotary vane part (2) are made into a whole after the forming material is produced by the pultrude process and then cut, thereby avoiding the defect due to the existence of a weld seam; the service life is long; the surface roughness of the pultrude forming material is high, so that the subsequent process is simplified, and the shavings wasted by the operating procedures of drilling, boring, shaving, milling, etc. can be saved. The rotary vane parts with different specified lengths can be obtained only by cutting according to a determined length without the need of an extra casting die. Therefore, the processing efficiency is improved, and the production cost is remarkably reduced.
Description
Technical field:
The utility model belongs to the blower technology, particularly the improvement of Roots Blower Rotor.
Background technique:
Existing Roots Blower Rotor is made up of rotating shaft, axle sleeve, rotating vane, and rotating vane is made by the pipe of intercept usually, and axially welds and be connected in the axle sleeve outer wall and be the radial radiation shape, and axle sleeve and rotating shaft interference fit are fastening.Because Roots blower is high to the welding quality requirement by master and slave two rotor engaged work, otherwise rotating vane will rupture; Axle sleeve and the cast molding of rotating shaft one are also arranged in addition, and its follow-up brill, boring, operation such as to dig, mill loaded down with trivial details, and rotating vane length difference will be opened casting die in addition, the fabricating cost height.
The model utility content:
The purpose of this utility model provides the rotor of a kind of work efficiency height, Roots blower that cost of production is low.
The rotor of a kind of Roots blower of the utility model, by cooperate shaft sleeve part, the rotating vane portion of installing to form with rotating shaft, rotating vane portion is even radial radiation shape, and intercept is made one with shaft sleeve part and rotating vane portion after it is characterized in that making section bar by pultrude process.
The described quantity that is the rotating vane portion of even radial radiation shape is 3 or 4 or 5.
It is protruding that the top of described rotating vane portion is shaped on leaf.
The utility model is made one by metallic material intercept after pultrude process is made section bar with shaft sleeve part and rotating vane portion, has avoided the defective that existence produced by weld seam, long service life; Pultrusion material surface finishment is higher, has simplified subsequent technique, the swarf that operation such as saved brill, boring, dig, mill is wasted, the rotating vane portion of different size length only need block by preseting length and get final product, need not to open in addition casting die, work efficiency improves, thereby cost is obviously reduced.
Description of drawings:
Fig. 1 is the utility model five leaf rotor embodiments' a plan view;
Fig. 2 is the utility model four leaf rotor engaged state embodiments' a plan view;
Fig. 3 is the shape figure that the utility model pultrusion becomes trilobal cross material embodiment;
Fig. 4 utilizes Fig. 3 section bar to make the shape figure of three lobe rotor.
Embodiment:
With reference to Fig. 1, five leaf rotors are made up of shaft sleeve part 3, rotating vane portion 2, by pultrude process aluminum alloy or zinc alloy are made and to be cut into the Len req section behind the section bar and shaft sleeve part 3 and rotating vane portion 2 are made one, shaft sleeve part 3 centers have the axis hole that cooperates with rotating shaft 1 interference fit or key pin, the rotating vane portion 2 five leaf radial radiation shapes that are evenly distributed, each rotating vane portion 2 is shaped on gets empty through hole 22, can reduce material consumption; It is protruding 21 that the top of each rotating vane portion 2 is shaped on leaf, can strengthen the isolation performance of hyperbaric chamber and low-pressure cavity in the engagement rotation process.Five impeller structures have the higher air blast efficient of generation under low driving rotating speed.
Fig. 2 represents four leaf rotor engaged states, and its making method is identical with above-mentioned five leaf rotors, and mark 1 is a driving shaft among the figure, and mark 5 is a driven shaft.
Fig. 3 represents that pultrusion becomes trilobal cross material embodiment's shape figure, shaft sleeve part 3, rotating vane portion 2, through hole 22, leaf is protruding 21, axis hole 4 one pultrusion materials.
Fig. 4 utilizes Fig. 3 section bar to be cut into after the Len req section and rotating shaft 1 formed three lobe rotor shape figure is installed.
In order to reduce noise, to strengthen the isolation performance of hyperbaric chamber and low-pressure cavity, can apply one deck rubber layer (not drawing among the figure) at the Surface of action of rotor.
Claims (4)
1, a kind of rotor of Roots blower, by cooperate shaft sleeve part (3), the rotating vane portion (2) of installing to form with rotating shaft (1), rotating vane portion (2) is even radial radiation shape, and intercept is made one with shaft sleeve part (3) and rotating vane portion (2) after it is characterized in that making section bar by pultrude process.
2, the rotor of Roots blower according to claim 1, the quantity that it is characterized in that being the rotating vane portion of even radial radiation shape is 3 or 4 or 5.
