Description

Wynalazek niniejszy dotyczy sposo¬ bu i odpowiedniego urzadzenia, sluza¬ cych do szlifowania walków (rolek) stoz¬ kowych do lozysk rolkowych i ma na celu umozliwienie wydatnego i doklad¬ nego produkowania walków szlifowa¬ nych jednoczesnie w wiekszej ilosci.Istota wynalazku polega na tern, ze szli¬ fowanie uskuteczniane jest zapomoca dwu wirujacych tarcz szlifierskich o po¬ wierzchniach roboczych plaskich. Tar¬ cze te ustawione sa pod katem, odpo¬ wiadajacym katowi stozka walka. Same walki przesuwaja sie przytem pomiedzy powierzchniami roboczemi w kierunku równoleglym do linji przeciecia rzeczo- . nych powierzchni.Rysunek przedstawia schematycznie urzadzenie do urzeczywistnienia powyz¬ szego sposobu. Fig. 1 wyobraza widok przyrzadu zprzodu, a fig. 2 zboku.Przedstawione urzadzenie sklada sie z tarcz szlifierskich 1 i 2 o plaskich po¬ wierzchniach roboczych. Tarcze osa¬ dzone sa na osiach 3 i 4, lezacych w jed¬ nej i tej samej plaszczyznie i pochylo¬ nych do siebie pod katem równym ka¬ towi wierzcholka stozka szlifowanych w danym wypadku walków o. Tarcza 2y posiadajaca tutaj srednice mniejsza od tarczy ly lezy w okraglej kierownicy 6, która moze sie obracac okolo osi prostopadlej do osi tarczy, i spoczywa w prowadnicy 7, posiadajacej powierzch¬ nie walcowa 8, co pozwala zmieniac kat pomiedzy plaszczyznami roboczemi tarcz szlifierskich stosownie do kata. wierzcholka obrabianych walków stoz-kowych! Powierzchnia 7 spoczywa na podstawie 9, po której mozna- ja" prze¬ suwac wzgledem tarczy Szlifierskiej w kierunku prostopadlym do plaszczyz¬ ny roboczej tejze, celem zmieniania od¬ leglosci tarczy przy obróbce walków rozmaitej wielkosci.Walki 5 przesuwaj ac sie w korytku 10, które, z wyjatkiem boków walków, stykajacych sie z plaszczyznami robo- czemi tarcz szlifierskich, jest calkowicie zamkniete. Wobec tego walki stykac sie moga bez przeszkody z tarczami, co uwidocznia fig. 1. Korytko 10 moze tworzyc zamkniety obwód kola, ewen¬ tualnie przestawialny w kierunku pro¬ mieni tarczy, co pozwala na stopniowe doprowadzenie walków do wlasciwych wymiarów. Kierunek i szybkosc obrotu tarczy 1 i 2 zaleza od szybkosci ruchu walków w korytku.Do prowadzenia walków w korytku nadaje sie tasma transportowa, lancuch lub t. p., biegnace w korytku lub innej odpowiedniej prowadnicy i zaopatrzone w siodelka (do utrzymywania walków) o powierzchniach przylegajacych do walka w punktach przeciwleglych wzgle¬ dem osi podluznej lancucha lub tasmy. PLThe present invention relates to a method and a corresponding apparatus for grinding taper rollers for roller bearings and is intended to enable the efficient and accurate production of a greater quantity of grinded rolls at the same time. that grinding is effected by means of two rotating grinding wheels with flat surfaces. These discs are set at an angle corresponding to the angle of the battle cone. The fights themselves move between the working surfaces in a direction parallel to the intersection line. The drawing shows a schematic view of the device for implementing the above method. Fig. 1 shows a front view of the device and Fig. 2 shows a slope. The device shown consists of grinding wheels 1 and 2 with flat surfaces. The discs are mounted on axes 3 and 4, lying in the same plane and inclined towards each other at an angle equal to the cone top angle of the rollers polished in this case. The disc 2y having a diameter smaller than that of the disc is it lies in a circular steering wheel 6, which can rotate about an axis perpendicular to the axis of the wheel, and rests in a guide 7 having a cylindrical surface 8, which allows the angle of the grinding wheels to be changed according to the angle. the tip of the taper rollers to be processed! The surface 7 rests on a base 9, on which it is possible to "slide the grinding wheel in a direction perpendicular to the working plane of this, in order to change the distance of the wheel when processing rolls of various sizes. Rollers 5 move in the trough 10, which, with the exception of the sides of the rollers that touch the working surfaces of the grinding wheels, are completely closed. in the direction of the radius of the disc, which allows the rollers to be gradually brought to the correct dimensions. The direction and speed of rotation of the discs 1 and 2 depends on the speed of movement of the rollers in the trough. or other suitable guide and provided with saddles (for holding the rollers) with surfaces adjacent to the roller at points opposite to the m long axis of a chain or tape.

Claims

Patent claims. 1. The method of grinding taper rollers for cylindrical roller bearings, i.e. the grinding is effected by means of two rotating grinding discs, provided with flat working surfaces and set at an angle equal to the angle of the cone top of the grinded rollers during when fighting is conducted between shields in a direction parallel to the intersection line of said planes.

2. The device for implementing the method according to claim 1, characterized in that the two rotating grinding wheels with flat working surfaces are seated on separate axes intersecting at an angle equal to the angle of the cone of the rollers to be processed.

3. The device according to claim 2, characterized by the fact that the axes of the grinding wheels lie in one plane.

4. Device according to claim 2 and 3, characterized in that the grinding wheels can be rearranged with respect to each other, making it possible to change both the angle between their flat working surfaces and the distance of the discs.

5. The device according to claim 4, characterized by the fact that one of the grinding wheels is mounted in a circular slide, rotating about an axis perpendicular to the axis of the wheel and guided by guides, and adjustable perpendicularly to the working surface of the other grinding wheel.

6. The device according to claim 2 or 3, the area characterized by the fact that the rolls to be processed are placed in a trough, closed on all sides except those places where the rolls meet the discs, and fixed between the working surfaces of the grinding discs.

7. The device according to claim 6, characterized in that the trough for guiding the rolls forms a closed circle and can be moved parallel to the radii of the grinding discs.

8. The device according to claim 6 and 7, the area characterized by the fact that a conveyor belt, a chain or the like is provided in the trough on the fighting or in another suitable steering wheel, provided with seats for lateral guiding of the rollers and contacting the surface of the rollers in two diametrically opposed points when looking in the direction of the tray length.
