Abstract
A rotary wheel for a device processes a mechanical surface by applying centrifugal movement to sand blasting cleaning materials. The rotary wheel has an outer main wheel and an impeller wheel (10) disposed at the hub position and rotated together with the main wheel shaft, the main wheel has at least on vane fixed on one disc, these vanes are mounted with a distance from the rotary wheel hub (16), the impeller wheel (10) has a disc (11) with scoops (12), the impeller wheel scoops are at an angle (alpha) to the radial direction of the impeller wheel (10).
Description
The present invention relates to a kind of runner, it is used for by abrasive jet cleaning material centrifugal motion being carried out the device of mechanical surface treatment, have an outer main wheel and a turbine that is arranged in the wheel hub position with the coaxial rotation of main wheel, wherein main wheel has the blade that is fixed at least one dish, these blades and runner boss layout separated by a distance.
A kind of like this runner is known by DE 195 36 723 C2.The turbine of this known runner has blade equally, radially outward the lead blade of main runner of the abrasive jet cleaning material that these blades will be transported to the turbine hub position.Here the task of turbine is to make the abrasive jet cleaning material that arrives turbine be rotated motion early.Make the jet form even thus, thereby make the wearing and tearing of runner little.
Task of the present invention is to improve the runner of the above-mentioned type, makes the jet form more even.
According to the present invention, this task takes following measure to realize by a runner with the described feature of beginning: turbine has one the vaned turbine disk is set, and wherein the blade of turbine and turbine is radially angled.By this layout of turbo blade, can guide the blade of abrasive jet cleaning material better to main wheel.In addition, the abrasive jet cleaning material arrives the whole surface of primary blades equably, and specific wear is obviously more even mutually with known runner to make these blades.
Test shows, the abrasive jet cleaning material is injected into especially closely close turbine disk top causes the jet form even especially, particularly when the high rotating speed of runner.If blade exposes the wheel hub position of turbine or only protrude in turbine disk surface a little at this place, and one be used for the wheel hub position of the conveyance conduit one of abrasive jet cleaning material through to turbine, up to being close to turbine disk surface, then can improve the wearing and tearing of jet form and runner more.。
According to abrasive jet cleaning material and the Surface Machining task used, the blade of main wheel and the blade of turbine can be straight or curved.Also straight turbo blade and the primary blades of bending can be combined, perhaps also can conversely.Preferably blade is perpendicular to dish, but the part can favour dish at least.
In addition, in a kind of preferred form of implementation, the blade of main wheel and/or the blade of turbine can be arranged between two dishes.This known rotaring wheel structure own can be realized extra high stability.In addition, a shrouding disc being set has caused a kind of higher extruding of abrasive jet cleaning material is led with better.
Describe a kind of preferred embodiment of the turbine of runner of the present invention below in detail by accompanying drawing.
Be illustrated as
The plane of Fig. 1 turbine;
Fig. 2 is by the viewgraph of cross-section of turbine cutting line II-II shown in Figure 1.
Fig. 1 shows a turbine 10 with plane, has a turbine disk 11 and the blade 12 that is arranged on the turbine disk.At upside, blade 12 is covered by annular disk 13 parts that can be clear that especially from Fig. 2.Blade 12 not exclusively extends to the wheel hub position of the turbine disk 11, but reserves certain space for the abrasive jet cleaning mass transport herein.Therefore the abrasive jet cleaning mass transport can be transported to the top that is close to the turbine disk 11 always, makes the abrasive jet cleaning material radially outward be transported to unshowned main wheel by turbine 10 herein from the turbine hub position along the rotation (Fig. 1) of the direction of arrow 15.
As shown in Figure 1, blade 12 and turbine 10 radially 14 at an angle alpha, make the abrasive jet cleaning material guide the blade of unshowned main wheel hitherward very equably thus.Blade 12 is designed to roughly trapezoidal in side view.They are to the wheel hub direction of turbine 12 step-down gradually.
