Description
Technical field
The utility model relates to the rotating mechanism in machining center field, particularly a kind of machining center.
Background technology
On machining center, all can use bearing block and bearing at present, bearing be pressed in bearing block and with bearing block interference fit, and power transmission shaft when rotated, general rotating speed is all very high, therefore bearing heating is very serious, also can expand in the outer ring of bearing, the easy like this bearing deformation that causes, even can affect the normal operation of machining center, and also can reduce the service life of bearing.
Utility model content
In order to overcome the deficiencies in the prior art, the utility model provides that a kind of transmission is effective, the rotating mechanism of long-lived machining center.
The utility model solves the technical scheme that its technical problem adopts:
A kind of rotating mechanism of machining center, comprise the left shaft holder and the right bearing seat that are arranged on base, on described left shaft holder and right bearing seat, be separately installed with left bearing and right bearing, on described left bearing and right bearing, cross-under is useful on the screw mandrel of the movable workbench that promotes machining center, described screw mandrel is horizontally disposed with, servomotor for driving screw mandrel to rotate is installed on described left shaft holder, between described left bearing and left shaft holder, be provided with left axle sleeve, between described right bearing and right bearing seat, be provided with right axle sleeve, described left axle sleeve and right axle sleeve respectively with left bearing and right bearing interference fit, left axle sleeve and right axle sleeve are respectively and be matched in clearance between left shaft holder and right bearing seat, left axle sleeve is identical with the material of the outer ring of left bearing, right axle sleeve is identical with the material of the outer ring of right bearing.
In the utility model, the material of the outer ring of described left axle sleeve, right axle sleeve and left bearing, the outer ring of right bearing is bearing steel.
In the utility model, the both sides of described left shaft holder and right bearing seat are all extended with rectangular boss, be provided with and be convenient to the circular hole of bolt through boss on each boss.
The beneficial effects of the utility model are: the material of left axle sleeve is identical with the material of the outer ring of left bearing, the material of right axle sleeve is identical with the material of the outer ring of right bearing, therefore left bearing and left axle sleeve adstante febre can together with expand, and between left axle sleeve and left shaft holder, be matched in clearance, gap between left axle sleeve and left shaft holder is a buffer area, can effectively prevent that left bearing and left axle sleeve from deforming, therefore can effectively extend the service life of left bearing, in like manner, between right bearing and right bearing seat, be provided with right axle sleeve, also can effectively extend the service life of right bearing.
Brief description of the drawings
Below in conjunction with drawings and Examples, the utility model is described in further detail.
Fig. 1 is structural representation of the present utility model;
Fig. 2 is the enlarged drawing at A place in Fig. 1.
Detailed description of the invention
As shown in Fig. 1 ~ Fig. 2, a kind of rotating mechanism of machining center, comprise the left shaft holder 1 and the right bearing seat 2 that are arranged on base 10, on described left shaft holder 1 and right bearing seat 2, be separately installed with left bearing and right bearing 3, on described left bearing and right bearing 3, cross-under is useful on the screw mandrel 4 of the movable workbench that promotes machining center, described screw mandrel 4 is horizontally disposed with, servomotor 5 for driving screw mandrel 4 to rotate is installed on described left shaft holder 1, between described left bearing and left shaft holder 1, be provided with left axle sleeve, between described right bearing 3 and right bearing seat 2, be provided with right axle sleeve 6, described left axle sleeve and right axle sleeve 6 respectively with left bearing and right bearing 3 interference fit, left axle sleeve and right axle sleeve 6 are respectively and be matched in clearance between left shaft holder 1 and right bearing seat 2, left axle sleeve is identical with the material of the outer ring of left bearing, right axle sleeve 6 is identical with the material of the outer ring of right bearing 3.As preferably, the material of the outer ring of described left axle sleeve, right axle sleeve 6 and left bearing, the outer ring of right bearing 3 is bearing steel.The both sides of described left shaft holder 1 and right bearing seat 2 are all extended with rectangular boss 7, be provided with and be convenient to the circular hole of bolt through boss 7 on each boss 7.The material of left axle sleeve is identical with the material of the outer ring of left bearing, the material of right axle sleeve 6 is identical with the material of the outer ring of right bearing 3, therefore left bearing and left axle sleeve adstante febre can together with expand, and be matched in clearance between left axle sleeve and left shaft holder 1, gap between left axle sleeve and left shaft holder 1 is a buffer area, can effectively prevent that left bearing and left axle sleeve from deforming, therefore can effectively extend the service life of left bearing, in like manner, between right bearing 3 and right bearing seat 2, be provided with right axle sleeve 6, also can effectively extend the service life of right bearing 3.
The above, be preferred embodiments of the present utility model, but the utility model is not limited to above-described embodiment, as long as it reaches technique effect of the present utility model with any same or similar means, within all should falling into protection domain of the present utility model.
