Definitions

  • This invention relates to machinery bearin'gs as required by shafts intended to be revolved at a very high number of revolutlons per minute, and more particularly to mechanisms where great speed and precision is required, and consists substantially in the construction, combination and arrangement of parts hereinafter set forth and pointed out more particularly in the claims.
  • An object of the invention is to provide a journal means in which shafting may be supported and efficiently revolved at a substantially higher working rate than has heretofore been considered practical, although greatly desired for certain purposes.
  • Figure 1 is a fragmentary sectional plan-view of the invention as used to journal a grindingv wheel means in conjunction with an internal grinding mechanism
  • Fig. 2 is a cross sectional view taken in the proximity df line 2 -2 of Fig. 1
  • Fig. 3 is a broadside sectional view taken in the proximity of line 33 of Fig. 2,; and is a view of the same mechanism except that a polishing wheel is substituted for the grinding wheel shown in Fig. 1
  • Fig. 4c is a fragmentary sectional side .view taken in the proximity of line 4.4 of Fig. 2
  • Fig. 5 is a cross sectional view taken in the proximity of line 5-5 of Fig.
  • Fig. 6 is a fragmentary detailed plan as seen from the same viewpoint as Fig. 1, and how the invention may be used in connection with external grinding mechanisms;
  • Fig. 7 is a fragmentary end view taken in the proximity of line 77 of Fig. 3 and shows the polishing wheel means shown journalled. by the invention in Fig. 3;
  • Fig. 8 is a fragmentary sectional plan view illustrating the use of the invention as used in lapping, as understood in the realm of too] and die making;
  • Fig. 9 is a fragmentary sectional view as seen from the same viewpoint as Fig. 1, for indicating the manner of using the invention with plain bushing type bearings; and
  • Fig. 10 is shown for the same purpose, being a fragmentary sectional view as seen from the same viewpoint as Fig. 3.
  • the numeral 1 designates a shaft having a sleeve end 2 in which the taper shank 3 of the grinding wheel arbor 4 is co-axially engaged.
  • the miniature grinding wheel 5 is secured on the end of the arbor 4 by the nut means 6 in conventional manner.
  • Said grinding wheel is shown in grinding tangency with the interior cylindrical surface 7 of the work 8, which is a typical drill jig bushing, and which is being thus accurately ground to a desired inside diameter, as will be understood by those familiar with the art.
  • the numeral 9 desi nates an ordinary grinding machine chuc l r, the jaws 10 of which grip the work 8.
  • the shaft 1 is shown sectionally and in tangency with the three idler rollers 11, 12 and'13, which are distributed about same in orbit arrangement, it
  • rollers 14 and 11 are co-axially mounted on the difierent ends of the spindle 1'? adjacent its ordinary .ball bearings 19 and 18 which are conventionally supported within the frame 20.
  • rollers 15 and 12 are co-axially mounted on the spindle 21,
  • rollers 13 and 16 are also co-axially mounted on the different ends of the spindle 24, adjacent its ball bearings 25 and 26, which are supported within the oscillatable arms 27 and 28, respectively, said arms being free to swing on their pivotal screws 29 and 30, respectively, and thus guide roller 13 and 16 toward said shaft.
  • rollers 13 and 16 with the spindle 24 may be swung toward or away from-the shaft 1, by correspondingly swinging the arms 27 and 28 on .the pivot screws 29 and 30; and the shaft 1 being confined at one end between the roller 13 and the rollers 11 and 12; and at the otherend between the .roller 16 and the rollers 14 and 15, may be thus kept snugly retained in contact with all of said rollers, regardless of wear, or may be released for disassembling, as desired.
  • rotation of said shaft may be caused by rotation of any'ori all of the spindies 17 21 and 24, and said shaft may be thus driven by theaforesaid rollers, as well as journalled thereby.
  • the main ob- 'ect is that of complying with the required distance between the roller 13 and the rollers 11 and 12, as well as the distance between the roller 16 and the rollers 14 and 15, to keep said shaft crowded into thefinterceptioniof the rollers 11 and 12, and'of the rollers 14 and 15, Without allowing bearing play, and
  • the pulleys 31, 32 and 33 are formed on the spindles 17 21'and 24, respectively, between the aforementioned respective ball bearings thereof, and by referring to Fig. 5, it will bev seen that the central portion of the frame 20 .is left somewhat vacant to expose the outer cylindrical portions of said pulleys, by which arrangement the driving belt34 is threaded about onto working tangency with all of said pulleys.
  • Said spindles are thus driven by said belt and all of said spindles thus serve I to drive the shaft 1 thru the aforesaid rollers, by which arrangement it is made convenient to gear up the speed of the shaft lto a desirable high rate, due to the fact that the pulleys 31, 32 and 33 are of less diameter" than the aforesaid rollers, the shaft 1 being considerabl less in diameter than same.
  • t is a very important feature of this invention that the ordinary tautness of the belt 34 tends constantly to shift the rollers 13 and 16 withthe spindle 24, on the arms 27 and '28 toward .the shaft 1, thus automatically taking up for any wear on the different workfrictional resistance.
  • the grinding wheel 5 being also pivoted" as above mentioned, is used also whenever desired to grind the external cylindrical surfaces of work 36, which may be conveniently held in a typical grinding machine collet 37, usually considered a standard part of grinding machine equipment.
  • Fig. 7 illustrates the use of the polishing wheel 38 which may be used instead of the grinding wheel 5, when it is desired to polish such work as 39.
  • the shaft 1 may be used to drive a lapping tool 40, as shown in Fig. 8, which is substituted in the shaft 2 in place of the grinding wheel arbor 4, said tool being used as shown in lapping out a small hole in the work 41, which is conveniently supported in the chuck 42.
  • the shaft 1 is provided with shoulders 43 which together the rollers 11,
  • roller or bushing bearings may be substituted for the ball bearings 18, 19, 22, 23, 25 and 26 shown in Fig. 4 and Fig. 3.
  • the bearing for journalling the spindles 17, 21 or 24 is merely a matter of selection and is well within the realm of the subordinate.
  • rollers are conveniently retained in place on their respecti ve spindles, by screw means 45.
  • a clearance hole 46 is provided thru the frame for the shaft 1, and said shaft has no contact with the frames 20 or 52.
  • Removable plates 47 are secured to the ends of the frames 20 and 52 by the screw means 48 to conceal and protect the aforesaid rollers, bearings, shaft, etc.
  • the frames 20 and 52 are conveniently constructed of upper and lower section which are secured together by means of the screws 49.
  • the spindles 55 and 56 substituted for the spindles 17 and 21 are adapted to be journalled by the relatively fixed plain bushing type bearings 53. These bearings are fitted to the frame 52, which is substituted for the frame 20.
  • the spindle 54 shown in Fig. 10 is substituted for the spindle 24 being adapted to be journaled by the plain bushing bearings 53, and the arms 51 being also substituted for the arms 28 are adapted to carry the relatively fixed bushing bearings 53.
  • these two Figures 9 and 10 illustrate the manner of using plain bearings instead of ball bearings, in carrying the invention into ings shown in the other figures, it being understood that the invention is in no way restricted to the particular style of Journahng the spindles 17, 21 and 24.
