Abstract
Description
Invenția se referă la un lagăr cu rostogolire pentru tamburele morilor cu bile destinate procesării minereurilor.The invention relates to a roller bearing for the drums of ball mills intended for ore processing.
Este cunoscut un lagăr pentru tamburele morilor cu bile, prezentat în brevetul US 4013233, la care tamburul morii este prevăzut cu niște fusuri care se sprijină pe niște lagăre de alunecare.A bearing is known for the ball mill drums, disclosed in US Pat. No. 40,13233, at which the mill drum is provided with spindles that rest on sliding bearings.
Problema pe care o rezolvă invenția constă în reducerea pierderilor de putere datorate frecărilor din lagăre.The problem solved by the invention is to reduce the power losses due to friction in the bearings.
Lagărul cu rostogolire pentru tamburele morilor cu bile, conform invenției, are un suport vertical fixat într-o fundație, pe suportul vertical fiind dispuse, pe un arc de cerc, echidistant, niște role, pe care se sprijină un bandaj prevăzut cu un guler, care este presat pe un fus al tamburului morii, rolele fiind protejate cu ajutorul unui capac de etanșare fixat pe suportul vertical; rolele au o carcasă închisă cu un capac, în carcasă se află niște rulmenți radiali, între care se introduce un inel distanțier, rolele putându-se roti pe niște axe fixate în suportul vertical, etanșarea rulmenților radiali fiind asigurată cu ajutorul unor manșete de rotație, ungerea realizându-se cu ajutorul unui gresor.The roller bearing for the drums of ball mills, according to the invention, has a vertical support fixed to a foundation, on the vertical support being arranged, on a circle arch, equidistant, some rollers, on which a bandage provided with a collar is supported, which is pressed on a spindle of the mill drum, the rollers being protected by means of a sealing cap fixed on the vertical support; the rollers have a closed housing with a lid, in the housing there are radial bearings, between which a spacer ring is inserted, the rollers being able to rotate on axes fixed in the vertical support, the sealing of the radial bearings being ensured by means of rotating cuffs, greasing by means of a grease.
Lagărul cu rostogolire pentru tamburul morii cu bile conform invenției prezintă următoarele avantaje:The roller bearing for the ball mill drum according to the invention has the following advantages:
- reducerea frecărilor;- reducing friction;
- reducerea gabaritului;- reducing the size;
- fiabilitate mărită.- increased reliability.
Se dă, în continuare, un exemplu de realizare a invenției în legătură și cu fig. 1...3, care reprezintă:The following is an example of embodiment of the invention in connection with FIG. 1 ... 3, which represents:
- fig. 1, vedere laterală a lagărului;FIG. 1, side view of the bearing;
- fig. 2, secțiune prin lagăr cu un plan I -1, redat în fig. 1;FIG. 2, section through the bearing with a plane I -1, shown in fig. 1;
- fig. 3, schema de încărcare a lagărului.FIG. 3, load bearing scheme.
Lagărul cu rostogolire pentru tamburele morilor cu bile pentru procesarea minereurilor conform invenției, are un suport 1, vertical, care este fixat pe o fundație 2. Pe suportul 1, vertical, sunt dispuse echidistant, pe un arc de cerc, niște role A, pe care se sprijină și se poate roti un bandaj 3, care este presat pe un fus 4, al unui tambur C, al morii.The roller bearing for the drums of ball mills for processing ores according to the invention, has a vertical support 1, which is fixed on a foundation 2. On the vertical support 1, are arranged equidistantly, on a circle arc, some rollers A, on which supports and can rotate a bandage 3, which is pressed on a spindle 4, of a drum C, of the mill.
Pentru protecția rolelor A, suportul 1 vertical este prevăzut cu un capac 5, de etanșare.For roller protection A, the vertical support 1 is provided with a sealing cover 5.
Rolele A au o carcasă 6, inclusă cu un capac 7. în interiorul carcasei 6 se află niște rulmenți 8 și 9 radiali, separați cu ajutorul unui inel 10, distanțier.The rollers A have a housing 6, included with a cover 7. Inside the housing 6 are some radial bearings 8 and 9, separated by means of a ring 10, spacer.
Rolele A se rotesc în jurul unor axe 11, fixate în suportul 1, vertical.Rollers A rotate about axes 11, fixed in the support 1, vertically.
Bandajul 3 este prevăzut cu un guler a, pentru preluarea forțelor axiale.The bandage 3 is provided with a collar a, for taking over the axial forces.
Pentru etanșarea rolelor A, în carcasa 6 și capacul 7 sunt prevăzute niște manșete 12 și 13, de rotație, iar pentru ungere, un gresor 14.For the sealing of the rollers A, in the housing 6 and the cover 7 there are provided sleeves 12 and 13, of rotation, and for lubrication, a grease 14.
