The present invention relates to mechanism for driving rolls and for adjusting the positions thereof in directions at right angles to their axes. More particularly, the invention relates to mechanisms by means of which the rolls of printing machines, paper or coating machines and similar mechanisms may be positioned in variably adjustable positions with a high degree of accuracy and facility.
In mechanisms, such as printing machines and paper coating machines and the like, there is need for positioning the impression-rolls and the back-up rolls adjustably so that they may be moved to and from their operating positions quickly and surely. It is essential in these mechanisms that the operating position of such rolls be accurately determined in order that the return movement to such positions may be facilitated.
In accordance with the present invention mechanism is provided by means of which rolls of the above character may be efiectively driven. A further object of the invention is to provide mechanism by means of which the axes of such rolls may be adjusted to and from desired operating positions.
Yet another object of the invention is to provide mechanism by means of which rolls of the above character may be driven effectively and, at the same time, readily moved from their opcrating to their inoperative positions.
These and other objects of the invention are accomplished by means of an eccentric bearing mechanism and operating elements therefor in which the drive mechanism for the roll is carried with the member that is eccentrically adjusted and in order that theinvention may be readily understood, it will now be described in connection with the accompanying drawings, wherein Figure 1 is a view in end elevation, partly in section and with certain parts omitted, showing the manner in which the bearing adjustment of the present invention is accomplished;
Figure 2 is a view in longitudinal section, taken on the line 22 of Figure 1, and looking in the direction of the arrows; and
Figure 3 illustrates the manner in which the journal shaft of the roll shown partially in Figure 2 is journaled eccentrically remote from the end shown in Figure 2.
Referring more specifically to the above drawings, a roll is illustrated as being mounted in side frame members II and 12. The roll may be the backup roll of a paper coating machine, the impression roll of a printing machine, or any roll which is to be driven and the position of which is to be adjusted in a direction transverse to its axis.
10 Claims. (Cl. 74-395) Carried within the side frame members It and I2 are concentric shells l3 and I4, respectively, which are suitably secured within cylindrical portions l5 and It by hearing caps Ila. Within shells l3 and I4 eccentric bearing members I! and I8 are journaled by means oi. bearings l9 and 20. Journal shafts 2| and 22 are formed on the roll III at its opposite ends and are received within the respective eccentric bearing members I! and I8, being journaled therein by bearings 23 and 24, respectively. If desired, thrust bearings 25 may be formed between the journal shafts 2| and 22, and the respective eccentric bearing members l1 and I8. A hollow extension 21 is formed on the end of one of the journal shafts (in the form of the invention 11-- lustrated, this being journal shaft 2|), and a radial bearing 28 is carried within this hollow extension for a purpose presently to be described.
Each of the eccentric bearing members I l and I8 is formed with an arm 29 (Figure 1) having a bifurcated extremity 30 which receives trunnions 3! carried by a push-pull rod 32 that is moved axially by an electric motor 33 mounted upon the frame members I l and I 2. A suitable connection is provided for transforming the rotary motion of the motor into an axial motion, this mechanism not being illustrated in detail as it involves no part of the present invention. For example, the mechanism could consist of a nut and screw thread structure, but the details thereof need not be illustrated.
The lower end of each rod 32 is formed with a threaded portion 34 which is slidably received in a stop lug 35 fixed to the adjacent frame,
members II and I2. Adjustable nuts 36 and 31 are threaded on the extremity 34, and upon opposite sides of the stop lug 35. The nuts 36 and 31 thus limit the axial or push-pull movement of the rods 32 and by means of the adjustment of the nuts, the extent of rotation of the eccentric members I! and I8 may be effectively and accurately controlled. In this fashion, since the motors 33 are operated synchronously, the adjustment of both journal shafts 2| and 22 is accomplished simultaneously and to the desired extent.
In order that the roll l0 may be driven, the eccentric bearing member I! is formed with a housing extension 38, the outer extremity of which is provided with a flange 33 to which an adapter housing 40 is secured, the adapter housing 40 serving to mount a motor frame 4| and also being formed with a supporting wall 42. The armature shaft 43 of the motor is journaled at one end in bearing 44 carried by the motor housing, and at the other end in a bearing 45 carried by a hub 46 formed on the supporting wall 42.
The right-hand extremity of the armature shaft 43 is provided with sun gear 41 which engages a plurality of planet pinions 48 that are journaled in a planet spider 49. The left-hand extremity of the planet spider is hollow to encompass the sun gear 41 and is journaled in a bearing 50 carried by the hub 46. The righthand extremity of the planet spider 49 is journaled in the bearing 28 carried by the journal shaft 2|, and the housing extension 38 is provided with a planetary ring gear 5| which is engaged by the planet pinions 48. of this structure, the planetary system, including the sun gear 41, planet pinions 48, and ring gear 5!, provides a. suitable gear reduction from the armature shaft 43, and a further reduction is provided by a second planetary system comprising a sun gear 52 driven by the planet spider 49 which sun gear engages a plurality of planet pinions 53 that also engage an outer ring gear 54 carried by the housing extension 38. The planet pinions 53 are journaled in a cylindricalplanet spider 55 that is journaled in the housing extension 38 by bearing 56 and is secured to the end of the journalshaft 2|, as illustrated at 51.
Suitable ventilating mechanism may be provided for the driving motor and conventional electric circuits and controls for controlling the operation of the drive motor within the motor housing ll. going mechanism provides a continued coaxial relationship between the journal shafts 2| and 22 and the drive mechanism therefor while, at the same time, provision is made for moving these elements bodily in a direction transverse to their axis. Y
While the invention has been described with specific reference to the accompanying drawings, it is not to be limited save as defined in the appended claims.
