Description

Mlyny pierscieniowe, przy który eh cialo lozysk podtrzymujacych elastycznie osa¬ dzone walce mielace objete jest wychwy¬ tami polaczonemi ze sprezynowemi dzwigniami, maja te wade, ze cisnienie czopów wychwytowo osadzonych wal¬ ców dziala na pokrywy lozysk. Wsku¬ tek tego sruby lozysk narazone sa na dzialanie wielkich sil, zwlaszcza ze przy podobnych urzadzeniach rozdrabniaja¬ cych wstrzasnienia sa nieuniknione. Po¬ woduje to latwe obluznianie sie lub pekanie srub, a zatem przerwy w ruchu.Wynalazek usuwa te wady w ten spo¬ sób, ze lozyska walców, osadzonych elastycznie, sa wykonane na wzór zna¬ nych lozysk o ruchu kulowym, jednak zaopatrzone sruba cisnaca, sluzaca do scisniecia panewek tylko od tej strony ? z której cisnienie nie dziala, tak, ze sruby wolne sa. od cisnien wywolanych praca maszyny. W ten sposób w czasie ruchu nie moze nastapic obluznienie srub, nacisk walców pozostaje staly i mielenie odbywa sie bez przeszkody.Rysunek przedstawia dwa przyklady wykonania wynalazku, a mianowicie: Fig. 1—mlyn pierscieniowy z dwoma lozyskami walcowemi, osadzonemi wy¬ chwytowo w pierscieniowatych podpo¬ rach, w widoku zboku; Fig. 2 — jedno z obu lozysk walca w widoku podluznymi czesciowym prze¬ kroju; Wreszcie fig. 3—lozysko walca, urno-cowane wychwytowo w widelkowatej podporze lozyska, w widoku zboku.Oba czopy walca 1 mlyna pierscie¬ niowego osadzone sa wychwytowo w zna¬ ny sposób, przez umocowanie ich lo¬ zysk w dzwigniach wychwytowych 2.W mysl' wynalazku lozyska osadza sie na sposób lozysk Sellersa tak, ze panewki 3 i 4 sa- scisniete bez uzycia srub pokrywy. W tym celu pierscien o obejmuje panewki 3 i 4 (fig. 1, 2); pierscien ten jest osadzony na dzwigni wychwytowej 2. Dolna czesc pierscie¬ nia ma srube 6, która mozna dociagnac dolna czesc lozyska, i która sluzy tylko do docisniecia do siebie obu panewek.Cisnienie robocze przenosi sie na pa¬ newke górna 4y której pólkolisty nadle- wek 8 pracuje w odpowiedniem wydra¬ zeniu 7.Jak wynika z fig. 3, mozna podporze panewki nadac takze ksztalt widel 9. PLRing mills, in which the bearing bodies supporting the elastically mounted grinding rollers are covered by traps connected to spring levers, have the disadvantage that the pressure of the journals of the escapement of the rollers acts on the bearing caps. As a result, the bearing bolts are exposed to great forces, especially as with similar crushing devices, vibrations are inevitable. This causes the bolts to loosen or break easily, and thus to interrupt the movement. The invention overcomes these drawbacks in that the bearings of the elastically mounted rollers are made in the manner of known ball-motion bearings, but provided with a tightening screw. , to squeeze the sockets only from this side? from which the pressure does not work, so that the screws are free. from the pressure caused by the operation of the machine. In this way, the bolts cannot be loosened during movement, the pressure of the rolls remains constant and the grinding is carried out without obstruction. The figure shows two examples of the invention, namely: Fig. 1 - ring mill with two cylindrical bearings, seated and gripping in ring-shaped the backs, in the side view; Fig. 2 shows one of the two roller bearings in a longitudinal partial section view; Finally, Fig. 3 shows the roller bearing, escaped in the fork-shaped support of the bearing, in view of the slope. Both pins of the roller 1 of the ring mill are escaped in a known manner by fixing their loops in the escapement levers 2.W The thought of the invention is that the bearings are mounted in the Sellers bearing manner so that the shells 3 and 4 are compressed without the use of cover bolts. To this end, the ring comprises shells 3 and 4 (fig. 1, 2); This ring is seated on the escapement lever 2. The lower part of the ring has a screw 6 which can be tightened on the lower part of the bearing and which only serves to press the two shells together. The working pressure is transferred to the upper bracket 4 which has a semicircular ridge. the tube 8 works in the corresponding condition 7. As is apparent from Fig. 3, the bearing of the bushing can also be given the shape of a fork 9. EN

1. Zastrzezenie patentowe. Mlyn pierscieniowy, przy którym ciala lozysk, niosacych elastycznie osadzone walce mielace, umieszczone sa w wy¬ chwytach, polaczonych z elastycznemi dzwigniami, tern znamienny, ze lozyska (3, 4, 5 i 9) sa urzadzone podobnie do znanych lozysk o ruchu kulistym, jedna¬ kowoz zaopatrzone tylko po stronie nie narazonej na cisnienie sruba cisnaca (6), sluzaca wylacznie tylko do wzajemnego dociskania panewek, tak, ze zadne sru¬ by nie sa narazone na cisnienie robocze.Do odpisu patentowego „Ys 284. Si^A §i o/la.51 PL1. Patent claim. Ring mill, at which the bearing bodies, carrying flexibly mounted grinding rollers, are placed in lugs, connected with flexible levers, a characteristic ground, the bearings (3, 4, 5 and 9) are arranged similarly to the known bearings with spherical motion, however, provided only on the non-pressurized side, a pressure screw (6) serves only to tighten the bushings against one another, so that no bolts are subjected to the working pressure.
