L
The position of the grinding spindle lon-- gitudiually of the extension sleeve is controlled and determined by means of an antilriction thrust bearing applied to the spindle in rear ofthe balls 19, and between the spindle and the rear'pertion 8a of the sleeve. This bearing is in tlieviorin of an inner casing element 21 applied to the spindle, an outer easing element 22 seated in the extension sleeve, and two series of rollingmembers in the forni oli balls lon cated between the casing); eleinents. The
. inner casing element is; held ixedly in position on the spindle by means oi a claiiipii'ig nut 24C screwed oi'i the spindle and bearing against the rear end olf the easing; clement.7 While, the outer casing' element held fixedly in position in the extension sleeve. by means of a clamping nut 25 screwed in tlie rear endfof the -sleeve and bearing; against said casing element, the nut loosely surrounding the nut 2l and being Yprovided with an inwardly projecting' annular (lange 26 extending;A at vthe rear ot' the nut il and formed with a central opening 'which el y surrounds the rear projecting' end oi'- the lgrinding spindle. The bearing 20 will thus receivethe end thrusts ol the grinding spindle exerted in botlid'irections eifectively support the same in an rection.
The sole function of the antit'iictioii ,rollingJ members 19 is to give radial supportito the spindle, their capability of travelinglon- 1Pgtudinally on the Smooth cylindrical bearing surface 13' preventing them from giving any axial support to the spindle, such latter support'being taken care of wholly by the bearing 20. By employing a plurality of series of these rolling members coniined in circumferential grooves in the spindle, the latter is given Wide and extended radial support which insures trueness and accuracy in centering and running. while at the saine time there will be no possibility of the 'parte binding` in the event of ii slight endwise de iection of the spindle such as inig'ht occur from expansion or contraction or from other causes. In such abnormal actions of the spindle the rolling members will travel longitudinally along the smooth bearing surface and the parts Will in this manner aecoininodate themselves without interference or bindine.
It Will be observed that the grinding spindle is sustained and mounted Wholly within the extension sleeve, wliiclilatter is in turn detachably connected 1with the sustaining sleeve by the clamping nut 9 so that by the removal of thisjnut the extension and ill axial iiisleevc andthe contained bearings and grind ing' fpindle may be removed as a wholeendwise the Sustaining sleeve7 thereby permitting ready access to the bearings and operative parte, the slotted end of the spindle in this action disengaging in an endvvisedirection from the. driving lug on the shaft.
ln the foregoing construction andncco'mpanying drawings l have set forth inl vention in the particular detailed forni-and construction which l prefer to adopt. lt
till be. manifest, however, that various changes may be made in the details Without departing from the limits of the invention; and further it will be understood that' the invention is not limited to any particular form or construction of the parts except in so far as such limitations claims.
laving thus described my invention,
provided viitn an internal bearing)r surface, a rot ry drive shaftrnounted in said frame, a
el indir spindle extending Within the bearing surliace and flexibly connected with the drive shait no be rotated thereby, and a plu-i 'rality of antifriction rolling members between the spindle and bearing surface and giving radial su` port only to the spindle, said rolling mein ers beingl confined to circumferential travel on one of said parts and being adapted to track both circumferentially and axially on the other partJ 3. The combination of a sustaining frarne provided with an internal bearing surface, a rotary shaft mounted in said frame, a grinding' spindle extending Within said been inl;` surface and flexibly connected with the shalt to be rotated thereby'one of said parts being provided with circumferential grooves and the. other part having` a plane surface, and a plurality of antilriction rolling inembers mounted in saidv grooves in one of the parte and tracking both circumferentially and axially on the plane surface of the other part and giving only radial support to the spindle.
The combination of a sustaining iframe provided with. an internal cylindrical bearing surface, a rotary drive shaft mounted in said traine, a grinding spindle extending Within the hearinfr surface and lieifibly connected with the diiving shaft to be rotated.
arerspeciiied in the* s.. combination of a sustaining viraine i ies iis
thereby, said spindle being provided with a plurality of circumferential grooves, and
. antifriction rolling members located in said grooves and tracking on said bearing surface both circumferentially and axially and giving only radial support to the spindle.
5. The combination of a sustaining frame provided with an internal smooth cylindrical bearingy surface, a rotary drive shaft mounted therein, a grinding spindle extending within the bearing surface and flexibly connected with the shaft to be rotated thereby, antifriction rolling members between the spindle and bearing surface in position to track both circumferentially and axially on the bearing surface and giving the grindin spindle radial support only, and additiona antifriction rolling` members between the frame and spindle to give axial support to the spindle.
6. The combination of a sustaining sleeve, a rotary driving shaft mounted therein, an extension sleeve xedly connected with'the sustaining sleeve and provided with an internal smooth cylindrical bearing surface, a grinding spindle extending within the extenlsion sleeve and flexibly connected with the driving shaft to be rotated`thereby, antifriction rolling members between the spindle and bearing surface in position to track both circumferentially and axially on said bearing surface and giving radial support only to the spindle, and a thrust bearing between the spindle and extension sleeve to give axial support to the spindle. i
. The combination ofla sustaining sleeve,
a rotary drive shaft mounted therein, an extension sleeve havingits inner end extendin within the end of the sustaining sleeve an detachably connected therewith, the outer portion of the extension sleeve beingA provided with an internal smooth cylindrical bearing surface, a spindle extending within the extension sleeve, antifriction rolling members between the spindle and bearing surface togive radial rotary support only to the spindle, an antifriction bearing surrounding the spindle inward of said rolling members to give axial support to the spindle, said antifriction'bearing comprising an inner casing element applied to the spindle, an outer casing element seated in the extension sleeve, and rolling members between said casing elements, a clamping nut screwed in the inner end of the extension sleeve and engaging the outer casing element to hold the same in position, and a clamping nut screwed on the spindle and engaging the inner casing element to hold the same on the spindle, the inner end of the spindle being extended beyond said clamping nuts and being flexibly connected with the said drive shaft to be rotated thereby.
In testimony whereof, I have affixed my signature hereto.
