Definitions
- the invention relates to a Sprüharmlager for rotatable Lü ⁇ tion of a spray arm on a liquid inlet.
- a conventional spray arm bearing comprises a bearing collar with a bearing surface on which a spray arm is rotatably mounted.
- a baffle surface is connected to the bearing ring, which deflects a liquid flow flowing axially through the bearing ring from the axial to the radial flow direction, whereby the liquid flow enters the spray arm leg.
- the baffle is connected to the bearing ring, so that the recoil is derived by deflecting the bearing ring and does not affect the spray arm itself. This reduces the axial forces in the Sprüharmlagerung and the static friction or sliding friction is significantly reduced.
- the baffle surface and the bearing shell are initially produced separately and connected to one another, or the injection molding tool is constructed in three parts from an upper punch, a lower punch and a slide.
- the slide is inserted into the space between the bearing ring and the impact surface, and after curing, the slide is pulled out of the spray arm bearing intermediate space simultaneously with the retraction of the upper and lower punches.
- Both methods are therefore alswen ⁇ dig, as several steps or a complex spray tool are required. It is therefore the object of the invention to design a spray arm bearing such that it can be produced cost-effectively.
- the base area of a flow-directing device which effects a deflection of a liquid flow in the radial direction from a liquid flow in the radial direction, is at most as large as the base area of a passage opening in a bearing element of the spray arm.
- the outer contour of the base area of the flow-guiding device is thus at most congruent with the base area of the through-opening or lies within the base area area of the passage opening. If the base surfaces of the flow guide device and the passage opening are, for example, round, the diameter of the flow guide device is less than or equal to the diameter of the passage opening in the bearing element or bearing ring.
- an injection molding tool with only two spray cups or injection punches can be used to produce a one-piece spray chamber, ie a spray arm bearing formed in an injection molding process.
- an injection stamp is provided running from the bearing element side partially through the passage opening in the direction Strömungsleitein- direction, while from the direction of StrömungsleitINA a counter punch is delivered, which adjoins the outer contour of zuge ⁇ through the through hole stamp provided to the outside. It is therefore not necessary to connect the flow guide and the bearing element in a separate step with each other, nor to provide a slide in the injection molding tool, which after the Spraying must be driven out laterally (in the radial direction) from the opening area between the flow guiding device and the bearing element.
- the flow guide device can be structured rotationally symmetrically on the inside in a three-dimensional direction, which would not be possible if a lateral slide were used in the injection molding tool.
- Fig. 1 is a perspective view of a Sprüharmlagers
- FIG. 2 shows the spray arm bearing of FIG. 1 connecting an inlet and a spray arm in the installed state.
- the spray arm bearing 1 serves to connect an inlet 10 for supplying flushing fluid to a spray arm 20 which is rotatably mounted on the spray arm bearing 1.
- the spray arm bearing 1 comprises a bearing ring 2 with an outer bearing surface which is bounded in the axial direction (as shown in FIG. 1, upward) by an annular projection 7.
- a roof 3, which serves as a flow-guiding device, is connected via webs 4 to the bearing collar 2.
- the webs 4 extend substantially in the radial direction, while the width is minimized in the circumferential direction, so that the webs 4 of the fluid flow deflected in the radial direction counteract a low flow resistance.
- axially projecting notches 5 are arranged on the bearing ring, with where the Sprüharmlager 1 is engaged in an outlet opening on the inlet 10 (Fig. 2).
- the guide cone 6 serves for deflecting the flushing liquid, which flows essentially in the axial direction, in the radial direction.
- the recoil caused by the deflection is absorbed by the roof 3 and forwarded via the webs 4 to the bearing ring 2, which in turn is fixed to the inlet 10 after latching.
- the force exerted on the spray arm by the liquid feed in the axial direction is minimized, so that the friction of the spray arm 20 on the bearing surface of the bearing collar 2 is low.
- the inlet 10 is composed in two parts of an upper shell 11 and a lower shell 12.
- the upper shell 11 of the inlet 10 has a round outlet opening for the rinsing liquid, in which the detents 5 engage and thus fix the Sprüharmla ⁇ ger 1 at the inlet 10.
- the rinsing liquid enters from the left into the inlet 10 and is a ura steered at the right end through the opening in the axial direction and introduced into the spray arm 20.
- the spray arm 20 is shown cut in Fig. 2 in the transverse direction, that is, the boom of the spray arm extend in the plane of the drawing and out of the plane.
- the spray arm is composed of an upper shell 21 and a lower shell 22 and at its inlet opening, through which the rinsing liquid enters from the inlet 10, has an inner surface which acts as an abutment 23 to the outer bearing surface of the bearing collar 2.
- the flow arrows show very schematically the inflow of the liquid from the left, the axia- Ie ümlenkung, and the subsequent radial distribution through the Leitkonus 6 of the roof 3, wherein the Leitkonus 6 initially distributed rotationally symmetrical, but the flow is redirected by the limitation of the Sprüharminnenraums to the Sprüharmschenkeln.
- the upper and lower bowls 21, 22 are inserted into the spray arm and then the connection is made so that the spray arm bearing 1 is freely rotatable but axially within the spray arm is inserted in compliance with a game between the top of the roof 3 and the inside of the upper shell 21.
- the spray arm bearing 1 enclosed in the spray arm 20 is then latched onto the inlet 10.
- the bearing shown in FIG. 2 and thus the spray arm bearing 1 can be used in any bearing orientation, e.g. with suspended storage or vertical storage of the spray arm. '
- a first punch is delivered axially coming from the direction of the roof 3 and a second punch is delivered axially from the direction of the bearing collar 2.
- the lower bearing punch engages through the passage opening in the bearing ring 2 and its upper side forms the surface of the guide groove 6 and an inner part of the webs 4.
- the upper counter punch forms the upper side of the bearing ring 2 and of the roof 3 and comprises the part of the webs 4, as far as they project beyond the outer diameter of the plate 3.
- the outer diameter D 2 of the roof 3 is smaller than the limiting inner diameter D 1 of the liquid passage opening of the bearing collar 2.
- the diameter D2 is less than or equal to the diameter Dl.
