Definitions
- the technical environment of the invention for example, to DE 196 32 275 A1 directed.
- a sealing and bonding method for component joints in particular a method for sealing and / or bonding components from metallic materials in the automotive and engine industries, for example of components for engine blocks, oil sumps, gaskets, etc. described.
- the method is characterized in that in at least one of the joining surfaces provides at least one groove, the at least one filling opening having. You add the two components to their joining surfaces in the desired Orientation together and brings a liquid sealant or adhesive through the Fill opening in the groove until the groove is substantially completely with the Sealant or adhesive is filled.
- a socket in one so glued / sealed component described.
- the invention is based on US Pat. No. 5,152,538.
- This is a shaft seal for a crankshaft of an internal combustion engine in one along the crankshaft axis split crankcase described.
- the shaft seal is with his holder in the geodetically lower lying Kurbeigephaseteil in one Recess arranged.
- the mounting flange of the lower lying Kurbeigephaseteils a Groove, in which a seal is inserted during assembly of the crankcase.
- the crankshaft is through the at one end of the crankcase arranged shaft seal outwards.
- a disadvantage of the prior art is the complicated Einnngung a groove in the half-round recess in the flange of the crankcase for the shaft seal.
- the object of the present invention is to provide a generic species that is easier to manufacture Show machine housing.
- FIG. 1 shows, in a highly abstracted schematic diagram, a central longitudinal section through a divided machine housing with split bearing points provided for in the dividing plane for a shaft to be inserted.
- FIG. 2 the lower machine housing part is shown in detail in perspective;
- the part-section AA which is shown greatly simplified in FIG. 3, is identified by the assembled machine housing.
- a shaft sealing ring to be inserted into the end face of this machine housing is shown in perspective in FIG. 4 in the form of a first exemplary embodiment.
- like components are designated by the same reference numerals.
- crankcase lower part and the reference numeral 2 the crankcase upper part of a divided in the (horizontal) dividing plane 3 crankcase of a reciprocating internal combustion engine referred to.
- These two crankcase parts 1, 2 are here also generally referred to as machine housing parts 1, 2, since the method described and the corresponding housing design is generally applicable to any split machine housing.
- split bearings 4 are provided in the parting plane 3 for a shaft to be inserted, not shown figuratively for simplicity. In the preferred application, this shaft is the crankshaft of the internal combustion engine.
- this (crankshaft) shaft projects through the two end bearing points 4 beyond the completed machine housing (or crankcase), for which reason a respective shaft sealing ring 5 is provided in the two end bearing points 4 (see FIG .
- a respective shaft sealing ring 5 is provided in the two end bearing points 4 (see FIG .
- FIG.2 In conjunction with these bearings 4 can be seen in Fig.2 in the rest in this used, of course, also shared plain bearing shells .
- the provided in the two machine housing parts 1, 2 bearings 4 must be processed together in the production process of this machine housing, including the two machine housing parts 1, 2 are initially assembled without inserted plain bearing shells and without inserted (crank) shaft, as in Fig.1 shown.
- the lying in the parting plane 3 so-called.
- Diverging flange 2a of the crankcase upper part 2 is placed on the corresponding so-called.
- Trennflansch 1 a of the crankcase lower part 1 without interposition of a seal.
- the two machine housing parts 1, 2 are screwed together, via the multiple in the separating flanges 1 a, 2 a provided screw 6.
- the machining of the bearings 4 as already briefly described above.
- this groove 7 provided in the separating flange 1a thus forms a channel closed in cross-section for receiving the liquid-sealing agent, which thus ensures (after hardening) an optimum seal in the dividing plane 3.
- the two grooves extend 7 'in each shaft seal 5 via whose entire measured in the direction of the shaft axis 9 width, so that these grooves 7 'are open to the outside.
- the injection holes 8 introduced the liquid sealant in the groove 7, it flows via the groove (s) 7 to the grooves 7 'of the shaft seals 5 and finally occurs visible at the front open ends.
- a groove in the shaft seal may be formed on the outside circumferentially. It is particularly advantageous if this circumferential groove in the direction of the shaft axis 9 extends helically. Now flowing - with reference to Figure 2 - the liquid sealant from the right-hand (provided in the separation flange 1a) groove 7 coming forth in this helical circumferential groove in the shaft seal 5, so this liquid sealant virtually orbits the shaft seal 5 and then passes into the opposite left side (in the separation In this design, it would thus be sufficient to introduce the liquid sealant only on the right in Fig.
- the left-side injection hole 8 should continue to be provided as a vent and as a control body for a complete filling the grooves 7, 7 'to act.
- a groove on the outside circumferential groove on the shaft seal 5 must not be helical.

Description
Im übrigen muß eine am Wellendichtring 5 außenseitig umlaufende Nut nicht schraubenförmig ausgebildet sein. Daneben können selbstverständlich eine Vielzahl weiterer Details insbesondere konstruktiver Art durchaus abweichend vom gezeigten Ausführungsbeispiel gestaltet sein, ohne den Inhalt der Patentansprüche zu verlassen.
Im übrigen kann insbesondere in Reparaturfällen von beiden Enden des durch die Nuten 7, 7' in den Trennfugen bzw. in der Trennebene 3 gebildeten Kanales aus das zunächst fließfähige und später aushärtende Dichtmittel in die Nuten 7 und 7' eingebracht werden, d.h. nicht nur über die erstgenannte(n) Einspntzbohrung(en) 8, sondern auch über die bereits erwähnte Entlüftungsöffnung(en), die sich beim Ausführungsbeispiel nach Fig.2 am vorderen Ende der Nuten 7' befinden, um auch in diesem Falle eine sichere Abdichtung zu gewährleisten.
