Abstract

The depressurising device for dismounting bearings or bushings from shafts or casings, used in machine building, according to this invention, consists of a bolt (1), on which a washer (2) is fastened. The outer diameter (a) of the washer (2) is greater than the outer diameter (b) of a bushing (3). Also, the bushing (3) has an inner diameter (c) greater than the outer diameter (d) of a bushing with collar (4). A nut (5) is used for tightening and loosening.

Description

Invenția se referă la un dispozitiv de depresat, destinat demontării rulmenților sau bucșelor de pe axe sau carcase, utilizat în construcția de mașini.The invention relates to a depressor device, intended for removing bearings or bushings from axles or housings, used in the construction of cars.

Sunt cunoscute dispozitive de depresat, constituite dintr-o tijă pe care alunecă liber un berbec și având niște pene ce sunt fixate cu niște știfturi de o pâlnie, ce cuprind rulmentul sau bucșa de depresat. Dezavantajul acestor dispozitive constă în aceea că nu sunt suficient de rigide și se deformează în cazul pieselor înțepenite sau cu strângere puternică.Devices are known to be depressed, consisting of a rod on which a ram slides freely and having feathers that are fastened with a pin of a funnel, comprising the bearing or bushing depressed. The disadvantage of these devices is that they are not sufficiently rigid and deform in the case of tight or tight parts.

Problema tehnică pe care o rezolvă invenția este realizarea unui dispozitiv de depresat rulmenți care să nu se deformeze la depresarea pieselor înțepenite sau cu strângere puternică.The technical problem that the invention solves is the creation of a bearing depressant device that does not deform when depressed by the tight or tight parts.

Dispozitivul de depresat înlătură dezavantajele de mai sus, prin aceea că este constituit dintr-un șurub pe care este fixată o șaibă, prevăzută cu un diametru exterior mai mare decât un diametru exterior practicat pe o bucșă, bucșa fiind prevăzută și cu un diametru interior mai mare decât un diametru exterior practicat pe o bucșă cu guler strângerea fiind asigurată de o piuliță.The depressor device removes the disadvantages above, in that it consists of a screw on which a washer is fixed, provided with an outer diameter greater than an outer diameter practiced on a bush, the bush being provided with an inner diameter more greater than an outer diameter practiced on a collar bush, the tightening being provided by a nut.

Dispozitivul conform invenției prezintă următoarele avantaje :The device according to the invention has the following advantages:

- construcție compactă și robustă;- compact and robust construction;

- rigiditate mărită.- increased rigidity.

Se dă, în continuare, un exemplu de realizare a invenției, în legătură și cu figurile 1 și 2, care reprezintă:The following is an example of an embodiment of the invention, in relation to Figures 1 and 2, which represents:

- fig.1, vedere de sus a dispozitivului;- Fig. 1, top view of the device;

- fig.2, secțiune axială prin dispozitiv.- Fig. 2, axial section through the device.

Dispozitivul, conform invenției, este constituit dintr-un șurub 1, de care este fixată o șaibă 2. Șaiba 2 este prevăzută cu un diametru exterior a mai mare decât un diametru exterior b practicat pe o bucșă 3. Bucșa 3 mai este prevăzută cu un diametru interior c mai mare decât un diametru exterior d practicat pe o bucșă cu guler 4.The device according to the invention consists of a screw 1, of which is fixed a washer 2. The shaft 2 is provided with an outer diameter greater than an outer diameter b practiced on a sleeve 3. The sleeve 3 is further provided with a inner diameter c greater than outer diameter d on a collar bush 4.

□ piuliță 5 asigură strângerea și desfacerea. Bucșele 2 și 3 se deplasează liber pe șurubul 1.□ nut 5 ensures tightening and unscrewing. The bushes 2 and 3 move freely on the screw 1.
