Pierwszenstwo: Zgloszenie ogloszono: 30.05.1973 Opis patentowy opublikowano: 26.04.1975 75651 KI. 47b,33/64 7h,l/02 MKP F16c 33/64 B21k 1/02 Twórcy wynalazku: Janusz Kowalczyk, Edmund Lewandowski, Waclaw Szumny Uprawniany z patentu tymczasowego: Fabryka Wyrobów z Proszków Spiekanych, Lomianki (Polska) Sposób prasowania i kalibrowania lozysk samosmarnych barylkowych Znane sa w metalurgii proszków metody pra¬ sowania lozysk barylkowych.Dotychczas znane i stosowane w produkcji me¬ tody polegaja na prasowaniu i kalibrowaniu lozysk stemplami kulistymi.Posiadaja one szereg wad i niedogodnosci pole¬ gajacych przede wszystkim na: pozostawiaja cy¬ lindryczna czesc kolnierza wystajaca za obreb kuli lozyska, wystepuja ograniczenia kata wychylenia lozyska w pracy, nie zapewniaja proporcjonalnego rozkladu gestosci. Ponadto wystepuja trudnosci montazowe oraz utrudnienia w poprawnosci wy¬ konania kulistych czesci lozyska.Celem wynalazku jest wyeliminowanie powyz¬ szych wad i niedogodnosci.Cel ten osiagnieto przez opracowanie nowego sposobu polegajacego na prasowaniu bryly zlozo¬ nej z dwu stozków scietych oraz czesci walcowej.Stozki te przylegaja swymi szerszymi podstawami do walca, nastepnie zas na kalibrowaniu w ten spo¬ sób uksztaltowanej bryly po spieczeniu stemplami kulistymi nadajacymi ostateczny ksztalt.Sposób wedlug wynalazku oraz jego istote naj¬ korzystniej zobrazowano na zalaczonych rysunkach na których fig. 1 przedstawia ksztalt lozyska ba¬ rylkowego wedlug dotychczasowego sposobu pra¬ sowania i kalibrowania, fig. 2. przedstawia ksztalt lozyska barylkowego otrzymanego sposobem we¬ dlug wynalazku.Sposób wedlug wynalazku polega na tym, ze pra- 10 15 20 sowana bryla stanowiaca dwa stozki sciete zlozone szerszymi podstawami z czescia walcowa jest bry¬ la opisana na ksztalcie gotowego lozyska barylko- wego-kulistego. Tak wyprasowana bryla podlega kalibrowaniu stemplami kulistymi nadajacymi ksztalt lozyska. Stemple kalibrujace wywieraja na¬ ciski w czasie kalibrowania od punktowych przez liniowe do powierzchniowych, co zapewnia doklad¬ ne otrzymanie ostatecznego ksztaltu geometryczne¬ go przy zmniejszonej pracy kalibrowania oraz za¬ pewnia dokladnosc rozkladu gestosci lozyska. Ob¬ jetosc figur obrotowych Vi i V2 zawartych pomiedzy tworzacymi stozka stycznymi do kuli i kula lo¬ zyska utworzonych przez obrót pól FA i F2 do okolo osi podluznej bryly lozyska musza byc sobie równe dla kazdego stozka scietego. Równosc tych objetosci daje gwarancje jednakowej pracy kali¬ browania w kazdym obszarze a zatem zapewnia po¬ prawna prace stempli i rozklad gestosci lozyska.Tak wykonane lozyska moga pracowac wahliwie teoretycznie bez ograniczenia wychylenia katowe¬ go. PL PLPriority: Application announced: May 30, 1973 Patent description was published: April 26, 1975 75651 KI. 47b, 33/64 7h, l / 02 MKP F16c 33/64 B21k 1/02 Creators of the invention: Janusz Kowalczyk, Edmund Lewandowski, Waclaw Szumny Entitled under a temporary patent: Factory of Sintered Powder Products, Lomianki (Poland) The method of pressing and calibrating bearings self-lubricating roller bearings There are methods of pressing roller bearings known in powder metallurgy. The methods known and used in production so far consist in pressing and calibrating the bearings with spherical punches. They have a number of disadvantages and disadvantages, mainly due to: they leave the cylindrical part the flange protruding beyond the edge of the bearing ball, there are limitations in the angle of deflection of the bearing at work, they do not ensure a proportional distribution of density. In addition, there are assembly difficulties and difficulties in the correct execution of the spherical parts of the bearing. The aim of the invention is to eliminate the above drawbacks and inconveniences. This aim was achieved by developing a new method consisting in pressing a body composed of two truncated cones and a cylindrical part. they adhere with their wider bases to the cylinder, and then on calibrating the shaped body in this way after sintering with ball punches giving the final shape. according to the previous pressing and calibration method, Fig. 2 shows the shape of a barrel bearing obtained by the method according to the invention. The method according to the invention consists in that the pressed body consisting of two truncated cones with wider bases from the cylindrical part is the block is described as a finished bearing a barrel-spherical. The block pressed in this way is calibrated with spherical stamps that give the shape of a bearing. The sizing dies exert pressure during calibration from point to line to surface, which ensures the final geometric shape is accurately obtained with reduced calibration work and the bearing density distribution is accurate. The volume of the rotational figures Vi and V2 contained between the cones forming the tangents to the sphere and the ball of the bearings formed by the rotation of the fields FA and F2 to about the longitudinal axis of the bearing body must be equal for each tangent cone. The equality of these volumes guarantees that the calibrating work is the same in every area and therefore ensures the correct work of the punches and the distribution of the bearing density. The bearings thus made can oscillate theoretically without limiting the angular deflection. PL PL
