Definitions
- the present finding concerns a bearing with threading on the surface of the inner hole and/or on the outer circumferential surface; it has application in the mechanical field, when it is required to be able to easily and precisely vary the axial position thereof in its housing, without having to reduce the axial load capacity during the aforementioned adjustment operations.
- the device according to the finding is also used in mechanical applications in which it is required to fix the bearing on a shaft or in a housing taking it into abutment against a shoulder, without the need to use other axial locking devices .
- the shaft can slide axially on the bearing, braked only by friction.
- the shaft is susceptible to sliding and positioning itself axially in an uncontrollable manner.
- the first purpose of the present finding is that of realising a bearing that allows the axial positioning of the shaft in the aforementioned bearing to be controlled and adjusted, even in the presence of axial loads.
- a further purpose of the finding is that of realising a bearing, which can be locked directly against a shoulder of the shaft and/or of the housing or of any other device that can block the axial sliding of said bearing, without the need to use attachment means such as ring nuts, screw nuts, bushes, elastic rings, covers and others with the consequence of a reduction in axial bulk of the support group of the shaft.
- Such purposes are achieved with a bearing characterised in that it has the surface of the hole and/or its threaded outer circumferential surface such as to allow the assembly of the aforementioned bearing on shafts and/or threaded housings.
- the bearing with the characteristics according to the finding is of the per se known type - sliding, rolling (with balls, with rollers, conical rollers, barrel rollers, small rollers) , axial and/or radial of whatever type, size and material; moreover, the inner ring and/or the outer ring can be threaded with any type of threading.
- the finding is intended to also extend to constructive solutions consisting of bearings with smooth surfaces, on which threaded bushes are fixed, which give the aforementioned bearings the typical operative characteristics of the aforementioned bearings .
- the finding is also intended to extend to bearings in which the outer ring and/or the inner ring or the possible bushes fixed to them are projecting and/or equipped with holes, slots, levellings, hexagons, collars and other impressions, which allow gripping with keys to generate the screwing rotation and determine the position on the shaft and/or in the housing of the bearing.
- the collars can also consist of end-of-screwing abutments .
- figs. 1 and 2 respectively represent a front elevated view and a plan view, sectioned according to the line H-II of fig. 1, of a first embodiment of the bearing according to the finding;
- figs. 3 and 4 respectively represent a front elevated view and a plan view, sectioned according to the line IV-IV of fig. 3, of a second embodiment of the bearing according to the finding;
- figs. 5 and 6 respectively represent a front elevated view and a plan view, sectioned according to the line VI-VI of fig. 5, of a third embodiment of the bearing according to the finding;
- figs. 7 and 8 respectively represent a front elevated view and a plan view, sectioned according to the line VIII-VIII of fig. 7, of a fourth embodiment of the bearing according to the finding;
