Abstract
The invention discloses a rotating mechanism of a machining center. The rotating mechanism comprises a left bearing seat and a right bearing seat which are arranged on a base, wherein a left bearing and a right bearing are arranged on the left bearing seat and the right bearing seat respectively; a lead screw for driving a workbench of the machining center to move is inserted into the left bearing and the right bearing, and is arranged horizontally; a servo motor for driving the lead screw to rotate is arranged on the left bearing seat; a left shaft sleeve is arranged between the left bearing and the left bearing seat; a right shaft sleeve is arranged between the right bearing and the right bearing seat; the left shaft sleeve and the right shaft sleeve are in interference fit with the left bearing and the right bearing respectively, and are in clearance fit with the left bearing seat and the right bearing seat respectively; the outer rings of the left shaft sleeve and the left bearing are made of the same material; the outer rings of the right shaft sleeve and the right bearing are made of the same material. The rotating mechanism has a good transmission effect, and is durable.
Description
Technical field
The present invention 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, and 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.
Summary of the invention
In order to overcome the deficiencies in the prior art, the invention provides that a kind of transmission is effective, the rotating mechanism of long-lived machining center.
The technical solution adopted for the present invention to solve the technical problems is:
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 present invention, 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 present invention, 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 bolt through the circular hole of boss on each boss.
The invention has the beneficial effects as follows: 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.
Accompanying drawing explanation
Below in conjunction with drawings and Examples, the present invention is further detailed explanation.
Fig. 1 is structural representation of the present invention;
Fig. 2 is the enlarged drawing at A place in Fig. 1.
The specific embodiment
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 bolt through the circular hole of 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 better embodiment of the present invention, but the present invention is not limited to above-described embodiment, as long as it reaches technique effect of the present invention with any same or similar means, within all should falling into protection scope of the present invention.
