Naprava za sprejem obdelovanca in ročno upravljanega motorno gnanega delovnega sredstvaA device for receiving a workpiece and a manually operated motor driven workpiece

Izum spada na področje delovnih postopkov, v okviru teh zadeva orodne stroje, v zvezi z njimi pa se zlasti nanaša na podrobnosti, sestavne dele oz. pribor za orodne stroje, ki niso vezani niti na določeno gradivo, ki se obdeluje, niti na določen rezultat obdelave.The invention relates to the field of working procedures, within the scope of these concerns machine tools, and in particular relates to details, components or components. accessories for machine tools that are not tied to either the particular material being processed or to the specific processing result.

Predmeti te vrste so v mednarodni razvrstitvi patentov uvrščeni npr. v razred B 23 Q 9/00, ko gre za obdelavo kovin, B 27 G 19/04, ko gre za pripomoček za olajšanje žaganja lesa ali podobnega gradiva s pomočjo ročno upravljanih motorno gnanih krožnih žag, D 06 H 7/00, ko gre za površinsko obdelavo ali razrez ali kak drug način deljenja tekstilnega gradiva.Subjects of this type are classified, e.g., in the international patent classification. to class B 23 Q 9/00 when it comes to metalworking, B 27 G 19/04 when it concerns a device for facilitating the sawing of wood or similar material by means of hand-operated motor-driven circular saws, D 06 H 7/00 when it is a surface treatment or cutting or some other way of sharing textile material.

Obstajal je problem, kako zasnovati pomožno napravo, ki bo po eni strani omogočala sprejem, po potrebi tudi pritrditev, obdelovanca, po drugi pa sprejem in držanje ročno upravljanega motorno gnanega orodja in izvajanje pomožnih gibov poljubno prostorsko nastavljenega obdelovalnega orodja, da bo obdelovalno orodje nenehno nadzorljivo in pri tem za nošenje pogonsko-obdelovalne orodne enote ne bo potreben mostni nosilec nad obdelovancem.There was a problem in designing an auxiliary device that would, on the one hand, accommodate, if necessary, attachment of the workpiece, and on the other hand, receive and hold manually operated motor-driven tools and perform auxiliary movements of any spatially adjusted machining tool to keep the machining tool constantly controllable without the need for a bridge carrier above the workpiece to carry the power-tooling unit.

EP 0 377 347 Al pod nazivom naprava za vodenje prenosnega stroja predlaga linijsko tirnično vodilo s kotalno uležajenim suportom, na katerega se namestijo pomožni, od vsakokratnega delovnega priključka odvisni aparaturni deli in pogonski stroj z delovnim priključkom in orodjem, pri čemer se to vodilo namesti neposredno na obdelovanec, ki je v tem primeru ploščat oz. iz plošče izhajajoč, vzdolž načrtovane linije obdelovanja. Tirnično vodilo po svojem bistvu predstavlja na nivo obdelovane površine spuščen mostni nosilec. Ta kot tak izključuje možnost tretiranja obdelovanca na območju znotraj lastnega tlorisa in je zato in tudi sicer področje uporabe te rešitve omejeno na sorazmerno specifične primere.EP 0 377 347 Al, under the name of a transmission control device, proposes a linear guide rail with a roller bearing to which auxiliary work-related auxiliary parts and propulsion machinery with a work attachment and tool are mounted, with this bus being installed directly per workpiece, which in this case is flat or flat. emerging from the plate, along the planned processing line. The rail guide is essentially a lowered bridge girder to the level of the work surface. As such, it excludes the possibility of treating the workpiece in an area within its own floor plan and, therefore, the scope of this solution is limited to relatively specific cases.

Iz proizvodnega programa tvrdke OMGA S.p.A. je pod trgovsko oznako radial arm saw znana naprava, ki obsega delovno mizo, ki je za prilagajanje obdelovalnim potrebam zamenljiva, izven delovne mize lociran sestavljen steber, katerega višinska razsežnost se lahko menja, in na skrajnem koncu tega stebra pritrjeno, okoli osi stebra zavihtljivo razporejeno konzolo z visečim suportom za sprejem in nošenje pogonsko-obdelovalne orodne enote. Pomanjkljivost te naprave je v tem, da se s približevanjem mesta pritrditve pogonsko-obdelovalne enote na konzoli proti stebru naprave preglednost nad orodjem naraščajoče zmanjšuje, tj. neizkoriščeni del konzole predstavlja precejšnjo oviro.From the production program of the OMGA hardcover S.p.A. a known device is known by the trade mark radial arm saw, comprising a workbench which is a replaceable, adjustable, off-the-counter workbench located outside the workbench, the height dimension of which can be changed and, at the extreme end of this pillar, pivotally arranged about the axis of the pillar. suspension bracket for receiving and carrying the power-tooling unit. The drawback of this device is that as the drive unit mounts on the console against the pillar of the device, the transparency of the tool decreases, ie. the unused portion of the console is a significant obstacle.

Slednjič pa DE 34 24 533 Al za potrebe obdelave gradiva v obliki proge predlaga mobilen, prečno na smer proge obdelovanca postavljen mostni nosilec, na katerem je z možnostjo premikanja vzdolž mosta razporejena nekakšna vaga, na katere enem prostem koncu je pritrjena pogonsko-obdelovalna enota. Kot pri prvoomenjeni rešitvi tudi tu ni izvedljiva delovna operacija neposredno pod mostnim nosilcem in naprava ne omogoča obdelave predmeta, katerega širina bi presegala svetlino pod mostnim nosilcem.Last but not least, DE 34 24 533 Al proposes a mobile, transverse, workpiece-mounted bridge girder for the purpose of machining material in the form of a line, on which a kind of scales are arranged along the bridge, with a drive-processing unit attached to one free end. As with the first-mentioned solution, a work operation directly below the bridge carrier is not feasible here, and the device does not allow the processing of an object whose width would exceed the brightness below the bridge carrier.

Po izumu je naprava za sprejem obdelovanca in ročno upravljanega motorno gnanega delovnega sredstva značilna po tem, da je adapter za sprejem motorno gnanega delovnega sredstva priključen od spodaj na pokončno, po višini prestavljivo cev, ki je povezana z vodoravno razporejenim konzolnim drogom, kotalno uležiščenim za izvajanje premočrtnega gibanja v okoli pokončne osi zasučnem ležiščnokotomernem sklopu, obešenem na prečni nosilec, ki je vpet med dvojico pokončnih nosilcev, razporejenih vzporedno z eno stranico delovne mize.According to the invention, a device for receiving a workpiece and a manually operated motor driven workpiece is characterized in that the motor driven workpiece receiving adapter is connected from the bottom to an upright, height adjustable tube connected to a horizontally spaced cantilever pole mounted performing a straight-line movement in an upright axis about a rotary bearing-mounted assembly suspended on a transverse support, which is clamped between two uprights arranged parallel to one side of the workbench.

Ležiščno-kotomerni sklop obsega križni kos in na tega priključena bočna ohišna kosa.The cam-bearing assembly comprises a cross piece and a lateral housing piece attached thereto.

Križni kos sestoji iz valjastega, na zgornjem odseku svoje plaščne površine s kotomerno skalo opremljenega dela, h katerega vznožju so priključena v tlorisni projekciji kvadraten obris tvoreča štiri prirobnična ušesa, ki po dve in dve nosita en bočni ohišni kos.The cross piece consists of a cylindrical, upper section of its mantle surface with an angular scale of the fitted part, to the base of which is connected, in the floor plan, a square outline of four flange ears, two and two bearing one lateral housing piece.

K omenjenima prirobničnima ušesoma je priključen vodoraven odsek (prečka) kot širinsko intenzivna črka H zasnovanega bočnega ohišnega kosa.A horizontal section (crossbar) is connected to the said flange ears as a width-intensive letter H of the lateral casing.

Vsakokratni, na vodoravni odsek vezani, pokončni krak črke H tvoreči odsek bočnega ohišnega kosa je v prečnem preseku zasnovan kot znak Σ, deformiran tako, da vsi notranji koti merijo 90°, pri čemer je zadevni odsek v vzdolžni smeri obojestransko omejen s prečno postavljenima zaplatama, in v s tema zaplatama omejeni zgornjo in spodnjo komoro vsakokratnega končnega pokončnega odseka bočnega ohišnega kosa je položajno držano vgrajen po en kotalni ležaj, ki sodeluje s površino konzolnega droga.The horizontal section of the letter H, which is connected to the horizontal section by the horizontal section, is in cross-section designed as a sign deform, deformed such that all internal angles measure 90 °, with the respective section being circumferentially circumferentially circumscribed by transversally arranged patches. , and the upper and lower chambers of each end upright section of the lateral housing piece, respectively, are restrained in position by one roller bearing in contact with the surface of the cantilever pole.

Osnovni sestavni del predmetne naprave je stojalo 1, ki v predstavljeni izvedbi sestoji iz dvojice pokončnih nosilcev 2, ki ju ob vrhu medsebojno togo veže prečni nosilec 3, in dvojice k vznožju vsakokratnega pokončnega nosilca 2 togo priključenih, na ravnino pokončnih nosilcev 2 in prečnega nosilca 3 pravokotno postavljenih, istosmiselno orientiranih vzdolžno ležečih nosilcev 4, na katera je od zgoraj togo priključena stalna delovna miza 5. Ta ima smotrno vgrajeno prislonsko letev 6 za potrebe naslanjanja obdelovancev.The basic component of the present device is a stand 1, which in the present embodiment consists of two uprights 2, which are rigidly connected by a transverse support 3 at the top, and two to the base of the respective uprights 2 rigidly connected to the plane of the uprights 2 and the transverse support. 3 perpendicularly aligned, axially oriented longitudinally supported beams 4, to which a permanent work table 5 is rigidly connected from above. It has a cleverly mounted stop rail 6 for leaning workpieces.

V ceneni oz. lahki izvedbi, za kakršno gre v predstavljenem primeru, so nosilci 2 in 4 pločevinasti oglati C-profili, nosilec 3 pa je cev četverokotnega, v danem primeru kvadratnega preseka. Nosilci 2, 3, 4 in delovna miza 5 so medsebojno vijačeni (povezani z vijaki).In the price or. the lightweight embodiments of the present case are the beams 2 and 4 of the sheet metal C-section, and the bearer 3 is a tube of quadrilateral, in this case square section. The supports 2, 3, 4 and the work table 5 are screwed together (connected by screws).

V območju sredine razpetine prečnega nosilca 3 med pokončnima nosilcema 2 je na nosilec 3 prosto položen podolgovat obesni nosilec 7, ki je v danem primeru zasnovan kot oglat ΓΊ-profil. Svetlina slednjeomenjenega (Ί-profila je v bistvu prirejena širinski stranici preseka prečnega nosilca 3, višina pokončnih sten ΓΊ-profila pri tem ne sega izpod spodnjega roba prečnega nosilca 3, dolžina obesnega nosilca 7 pa je smotrno odmerjena na rang velikosti okoli tretjine dolžine prečnega nosilca 3. (Očitno je, da se s tem togostno okrepi deformacijsko najbolj izpostavljeni odsek prečnega nosilca 3.)In the mid-span area of the transverse beam 3 between the vertical beams 2, an elongated pendant beam 7, which is optionally designed as a square profil profile, is freely placed on the beam 3. The luminosity of the latter (the profila-profile is substantially adapted to the cross-sectional width of the transverse beam 3, the height of the vertical walls of the profila-profile does not extend below the lower edge of the transverse beam 3, and the length of the suspension bracket 7 is reasonably measured to a rank of about one third of the length of the transverse beam 3. (Obviously, this will stiffen the deformation-most exposed section of the transverse beam 3.)

V območju pod obesnim nosilcem 7 je od spodaj k prečnemu nosilcu 3 prislonjena krožna plošča 8, katere premer je smotrno večji od dolžine obesnega nosilca 7.In the area under the suspension bracket 7, a circular plate 8 whose diameter is substantially larger than the length of the suspension bracket 7 is supported from the bottom to the transverse bracket 3.

Skozi krožno ploščo 8, prečni nosilec 3 in obesni nosilec 7 so od spodaj vloženi matični vijaki 9 (prim. delni prerez na sl. 2), v danem primeru po dva in dva na konceh obesnega nosilca 7, ki navedene elemente vežejo v tog sklop. Pri vijakih 9 gre za vijake z vgreznilno glavo, tako da noben del vijakov 9 ne štrli dol izpod krožne plošče 8.Through the circular plate 8, the transverse support 3 and the suspension bracket 7 are provided with the bottom screws 9 (cf. partial cross-section in Fig. 2), optionally two and two at the ends of the suspension bracket 7, which bind the above elements to the rigid assembly . Screws 9 are screws with a scraper head so that no part of the screws 9 protrudes down from the circular plate 8.

H krožni plošči 8 je od spodaj prislonjen ležiščno-kotomerni sklop 10, ki predstavlja enega ključnih sestavnih sklopov predmetne naprave. Zveza ležiščnokotomernega sklopa 10 z že predstavljenimi deli naprave bo razvidna iz nadaljnjega opisa.The bearing plate-housing assembly 10, which represents one of the key components of the subject device, is supported from the bottom plate 8. The connection of the bearing compartment assembly 10 with the parts of the device already presented will be apparent from the following description.

Ležiščno-kotomerni sklop 10 obsega križni kos 11, katerega osnovni sestavni deli so votel, pokončen, navzgor zaprt, dol odprt valjast del 12, katerega premer, ki se smotrno ujema s premerom krožne plošče 8, je nekajkrat večji od njegove višine, in k vznožju valjastega dela 12 priključena štiri prirobniČna ušesa 13 (sl. 1), ki so zasnovana in razporejena v skupni vodoravni ravnini tako, da v tlorisni projekciji tvorijo kvadrat, katerega stranica je v bistvu ali smotrno enaka premeru valjastega dela 12.The cam-bearing assembly 10 comprises a cross piece 11, the basic components of which are a hollow, upright, upwardly closed, downward cylindrical portion 12 whose diameter, which is expediently matched to the diameter of the circular plate 8, is several times greater than its height, and k four flanged ears 13 (Fig. 1) are connected to the base of the cylindrical part 12, which are designed and arranged in a common horizontal plane to form a square in plan view substantially or substantially equal to the diameter of the cylindrical part 12.

Votla notranjost križnega kosa 11 je prednostno, iz izdelovalnih razlogov, cilindrična. Stropna plošča 14 (sl. 3) valjastega dela 12 križnega kosa 11 je z notranje strani zasnovana z zvezdasto postavljenimi togostnimi rebri 15, ki v svojem stičišču, ki sovpada z geometrijsko osjo križnega kosa 11, tvorijo nekakšnemu pestu podoben nastavek 16.The hollow interior of the cross piece 11 is preferably cylindrical for manufacturing reasons. The ceiling panel 14 (FIG. 3) of the cylindrical part 12 of the cross piece 11 is internally formed by star-shaped rigid ribs 15 which, at its junction, coinciding with the geometric axis of the cross piece 11, form a hub-like attachment 16.

Obesni nosilec 7, prečni nosilec 3 in krožna plošča 8 so smotrno enotno prevrtani in skozi to skupno, sestavljeno luknjo je vložen stojni vijak 17 (sl. 3), ki je uvit skozi središčno vijačno luknjo stropne plošče 14 valjastega dela 12 križnega kosa 11 in na spodnji strani slednje, z naslonom na osrednjem nastavku 16, zategnjen s protimatico 18. Od zgoraj, z naslonom na obesnem nosilcu 7, je na stojni vijak 17 privita popuščalno-zategovalna matica 19, kije prednostno zasnovana kot zaprta in z manipulacijsko ročico zasnovana matica.The suspension bracket 7, the transverse bracket 3 and the circular plate 8 are conveniently drilled through and through this joint hole a stand screw 17 (Fig. 3) is threaded, which is threaded through the center screw hole of the ceiling panel 14 of the cylindrical part 12 of the cross piece 11 and on the underside of the latter, with a backrest on the central extension 16, tightened with a lock nut 18. From above, with a backrest on the suspension bracket 7, a loosening nut 19 is screwed onto the stand screw 17, preferably designed as a closed and manipulating lever. .

Plaščni pas na krožno ploščo 8 mejočega odseka valjastega dela 12 križnega kosa 11 je opremljen s sklenjeno 4x90-stopinjsko kotomerno skalo 20, katere po dve in dve delni skali, obsegajoče vsakokrat vrednosti 0-90°, se zbližujeta v eni smeri proti skupni 90-stopinjski in v drugi proti skupni ničelni točki (tako obstajata samo dve ničelni in dve 90-stopinjski točki).The plate belt on the circular plate 8 of the adjacent section of the cylindrical portion 12 of the cross piece 11 is provided with a contracted 4x90 degree angular scale 20, each of which has two and two partial scales, each having values 0-90 °, converging in one direction toward the total 90- degrees and in the second toward the common zero point (so there are only two zeroes and two 90 degree points).

V smotrni zasnovi je kotomerna skala 20 odtisnjena kot milimetrska skala na posebnem kovinskem traku in je ta prigrajen na primerno obdelano ležišče križnega kosa 11. Očitno je, da obseg valjastega dela 12 tedaj znaša 4x90 (= 360) mm, s čimer je dano eno od dimenzijskih izhodišč za realizacijo naprave.In a clever design, the gauge scale 20 is imprinted as a millimeter scale on a special metal strip, which is mounted on a properly machined cross piece 11. It is obvious that the circumference of the cylindrical part 12 then is 4x90 (= 360) mm, giving one of dimensional starting points for device realization.

Kotomerna skala 20 je postavljena tako, da se ničelni točki projicirata na krajišči ene umišljene srednjice zgoraj omenjenega kvadrata, tvorjenega po prirobničnih ušesih 13 križnega kosa 11, 90-stopinjski točki pa na krajišči druge. Primerjalni, t.j. stalni, kotomerni črtici za kotno nameščenje križnega kosa 11 in nanj vezanih delov naprave sta razporejeni na plaščni površini krožne plošče 8 v pokončni ravnini, potekajoči pravokotno na prečni nosilec 3 in skozi os stojnega vijaka 17.The gauge scale 20 is positioned such that the zero points are projected at the points of one imaginary median of the above-mentioned square formed along the flange ears 13 of the cross piece 11 and the 90 degree points at the points of the other. Comparative, i.e. the permanent, gauge bars for the angular positioning of the cross piece 11 and the parts thereof connected thereto are arranged on the mantle surface of the circular plate 8 in an upright plane extending perpendicularly to the transverse beam 3 and through the axis of the stand screw 17.

Nadaljnja sestavna dela ležiščno-kotomernega sklopa 10 sta bočna ohišna kosa 21 (sl. 4), ki sta od spodaj priključena na križni kos 11 tako, daje vsak obešen na dve prirobnični ušesi 13 križnega kosa 11 in sta postavljena medsebojno vzporedno in sta razmaknjena.Further components of the bearing and housing assembly 10 are lateral housing pieces 21 (Fig. 4), which are connected from below to the cross piece 11 so that they are each hung on two flange ears 13 of the cross piece 11 and are arranged in parallel and spaced apart.

Bočna ohišna kosa 21 sta v smotrni zasnovi medsebojno v bistvu enaka in glede na zgoraj omenjeno pokončno ravnino zrcalno simetrično postavljena. V pogledu v smeri pravokotno na pravkar omenjeno pokončno ravnino, t.j. vzporedno s potekom prečnega nosilca 3, zasnova bočnega ohišnega kosa 21 spominja na črko H, katere širina je nekajkratnik njene višine. Dolžina A (sl. 4) odseka 22 bočnega ohišnega kosa 21, ki v znaku H predstavlja njegovo prečko, je prirejena dolžini stranice zgoraj omenjenega kvadrata, tvorjenega po prirobničnih ušesih 13 križnega kosa 11.The lateral housing 21 is substantially identical to one another in the clever design and is mirror-symmetrically positioned relative to the upright plane mentioned above. In looking in a direction perpendicular to the just-mentioned upright plane, i.e. parallel to the course of the transverse beam 3, the design of the lateral housing 21 resembles a letter H whose width is several times its height. The length A (Fig. 4) of the section 22 of the lateral housing 21, which in its sign H represents its cross-section, is adapted to the length of the side of the above-mentioned square formed by the flange ears 13 of the cross-piece 11.

Za povezavo križnega kosa 11 z bočnima ohišnima kosoma 21 je skozi vsako uho 13 in odsek 22 speljana luknja, v katero je vložen matični vijak 23. Ta je v prednostni zasnovi postavljen tako, da njegova glava nalega na zgornjo površino ušesa 13, njegova matica pa od spodaj pritiska na odsek 22.To connect the cross piece 11 to the lateral housing pieces 21, a hole is inserted through each ear 13 and section 22 into which a nut screw 23 is inserted. In a preferred design, its head rests on the upper surface of the ear 13 and its nut from below press on section 22.

Kar se tiče lukenj za vijake 23, sta luknji v dvojici ušes 13, ki nosita enega od bočnih ohišnih kosov 21, podolgovati v smeri prečno na bočna ohišna kosa 21. (Gre za praktično sprejemljivo rešitev; sicer bi to veljalo za vse štiri luknje in za oba bočna ohišna kosa.) V vzdolžni osi vsakokratne podolgovate luknje ušes 13 je s proste, bočne strani vsakokratnega ušesa 13 speljana do omenjenega utora vijačna luknja, v katero je uvit vijak 24. Odsek 22 preostalega od dveh bočnih ohišnih kosov 21 je smotrno na svoji vodoravni srednjici - zasnovan s prečno v smeri proti prvemu ohišnemu kosu 21 potekajočo vijačno luknjo, v katero je uvit vijačni zatič 25, ki je opremljen s primernim gumbom za prijem s prsti. Alternativno, kar ni narisano, lahko vijačni zatič 25 zavzema le del debeline stene ohišnega kosa 21, preostanek debeline stene pa zavzema valjast nastavek.As for the holes for the screws 23, the holes in the two ears 13 bearing one of the lateral housing pieces 21 are elongated in the direction transverse to the lateral housing pieces 21. (This would be a practically acceptable solution; otherwise this would apply to all four holes and for both lateral housing pieces.) In the longitudinal axis of each elongated hole of the ear 13, from the free, lateral side of each ear 13, a screw hole is guided to said groove into which a screw 24 is screwed. Section 22 of the remaining of the two lateral housing pieces 21 is expedient to its horizontal center line - designed with a transverse screw hole transversely to the first housing piece 21 into which a screw pin 25 is provided, which is provided with a convenient button for gripping with the fingers. Alternatively, which is not drawn, the screw pin 25 can occupy only a portion of the wall thickness of the housing 21, and the remainder of the wall thickness is occupied by a cylindrical attachment.

Vsakokratni pokončni odsek 26 bočnega ohišnega kosa 21, ki v črki H tvori njen pokončni krak, je v pokončnem prečnem prerezu (sl 4), potekajočem vzporedno z npr. vijaki 24, 25, zasnovan podobno znaku X, ki je tako deformiran, da v njem nastopajo le koti 90° (na nasprotni strani: 270°). Odsek 26 je glede na odsek 22 razporejen tako, da se zgornji in spodnji zunanji lomni rob odseka 26 nahajata v isti pokončni ravnini kot bočna plaščna ploskev odseka 22.In each case, the upright section 26 of the side housing 21, which forms its upright arm in the letter H, is in the upright cross-section (FIG. 4) running parallel to e.g. screws 24, 25, designed similar to the character X, so deformed that only 90 ° angles (on the opposite side: 270 °) occur in it. Section 26 is arranged with respect to section 22 such that the upper and lower outer breaking edges of section 26 are in the same upright plane as the lateral mantle surface of section 22.

Odsek 26 nadalje obsega dve pokončni zaplati 27, od katerih je ena končna, druga pa meji na odsek 22. Zaplata 27 je zasnovana tako, da njen obris sledi zgornjemu in spodnjemu kraku profila X, veže zgornji in spodnji zunanji lomni rob profila X, prosta zgornji in spodnji konec profila X pa veže z obrisom, ki spominja na lomljen, štirisegmentni znak 3 (= na zrcalno sliko znaka X), pri katerem je prav tako prisotna značilnost, da vsi koti znašajo 90° (270°) in pri čemer se osrednji lomni mesti profilov X in 3 medsebojno dotikata.Section 26 further comprises two uprights 27, one of which is final and the other adjacent to section 22. The panel 27 is designed such that its outline follows the upper and lower arms of profile X, binds the upper and lower outer breaking edges of profile X, free the upper and lower ends of profile X are bound by an outline reminiscent of a fractured, four-segment sign 3 (= a mirror image of sign X), with the characteristic that all angles are 90 ° (270 °) and the central breaking points of profiles X and 3 are in contact with each other.

Rezultat te zasnove odseka 26 je, da odsek 26 z ene strani tvori dve v bistvu paralelepipedni, na dve strani odprti komori 28, z druge pa v bočno smer odprta, po svojem bistvu kot tristrana prizma zasnovana komora 29.The result of this design of section 26 is that section 26 forms, on one side, two substantially parallelepiped, open chamber 28 on two sides, and an open chamber laterally open, essentially a triangular prism-designed chamber 29.

Stena odseka 26 med komoro 29 in vsakokratno komoro 28 je prevrtana in v nastalo vrtino je vložen tulec 30. Na tulec 30, ki štrli v komoro 28, je s strani slednje nataknjen kotalni ležaj 31. Skozi tulec 30 je s strani zunanje komore 29 vložen vijak 32, na katerega je privita matica 33, ki posredno preko (neprikazanega) podložnega elementa pritiska na kotalni ležaj 31 in le-tega stiska k primerno urejeni ležiščni površini v komori 28.The wall section 26 between the chamber 29 and the respective chamber 28 is drilled and a sleeve 30 is inserted into the resulting hole. A roller bearing 31 is inserted into the sleeve 30 projecting into the chamber 28. The sleeve 30 is inserted through the sleeve 30 by the outer chamber 29. a screw 32 to which a nut 33 is screwed, which indirectly presses the roller bearing 31 and, via the (unshown) washer element, and presses it against a suitably arranged bearing surface in the chamber 28.

Čez matico 33 je na vijak 32 nataknjena pokrovna pločevina 34, ki tako zapira enega od dveh dostopov do komore 28 in ki s svojim zavihkom 35 (sl. 2) sega pred plaščno površino zaplate 27, kjer je med plaščno površino zaplate 27 in zavihkom 35 tornosklepno držan tračni vložek 36 polsti, katerega izven območja zavihka 35 štrleč prosti konec je zapognjen proti komori 28.Through the nut 33, a cover plate 34 is attached to the screw 32, which thus closes one of the two accesses to the chamber 28 and extends, with its tab 35 (Fig. 2), in front of the mating surface of the patch 27, where between the mating surface of the patch 27 and the flap 35 a thorn-locked ribbon insert 36 of felt, whose outside end of the tab 35 protruding free end is folded toward the chamber 28.

Pri zasnovi ležiščno-kotomernega sklopa 10, kot je opisan zgoraj, potemtakem obstajajo štiri kotalna ležiščna mesta, sestavljena iz po dveh kotalnih ležajev, postavljenih drug glede drugega pod pravim kotom, pri čemer po dva in dva ležaja definirata eno vodilno ravnino, skupaj štiri vodilne ravnine. Te so v prednostni zasnovi razporejene tako, da vzajemno tvorijo umišljen tunel kvadratnega preseka.In the design of the bearing and housing assembly 10 as described above, there are therefore four roller bearings, consisting of two rolling bearings, arranged at right angles to each other, with two and two bearings defining one guiding plane, together with four leading ones plane. These are arranged in a preferred design so that they mutually form an imaginary square-section tunnel.

Umišljenemu tunelu kvadratnega preseka je prirejen presek konzolnega droga 37, ki je vložen med kotalne ležaje 31 ležiščno-kotomernega sklopa 10. Morebitno prisotna geometrijska neskladja v legah kotalnih ležajev 31 se enostavno odpravijo s tem, da premakljivi bočni ohišni kos 21 primaknemo k drogu 37 (= popustimo vijaka 23 in po občutku zategnemo vijaka 24) in ga zatem spet fiksiramo.The imaginary tunnel of the square cross section is adapted for the cross section of the cantilever rod 37, which is inserted between the roller bearings 31 of the bearing and housing assembly 10. The geometrical discrepancies present in the positions of the roller bearings 31 can easily be eliminated by moving the movable side housing 21 to the pole 37 ( = loosen the screws 23 and tighten the screws 24) and then fix it again.

Konzolni drog 37 je smotrno jeklena, na ravnih ploskvah obrušena, galvansko cinkana in zatem pasivirana (pasivirati -> umetno oksidirati z dušikovo kislino, da se površina prekrije s plastjo tankega, v danem primeru cinkovega, oksida) cev kvadratnega preseka s posnetimi ali zaokroženimi vzdolžnimi robovi.
