Definitions

  • This invention relates generally to the combination of a splined shaft and a member for guiding the shaft for longitudinal movement while imparting rotary motion thereto, and more particularly to yan adjustable splined pinion incorporating means for removing back-lash from the splined shaft.
  • stator winding apparatus incorporating a winding head which is caused to move through the bore of ⁇ the stator being wound in a generally rectilinear path in order to wind coils in the stator slots.
  • This rectilinear motion of the winding head is provided by mounting the winding head upon a splined shaft which is guided yfor longitudinal movement and simul-taneously rotated by a splined pinion.
  • Another object of my invention is to provide an adjustable splined pinion for a splined shaft.
  • My invention in its broader aspects provides an externally splined shaft and an internally splined device for accommodating relative longitudinal motion of the shaft.
  • the internally splined device comprises first and second relatively rotatable parts each having ⁇ an internally splined portion with the shaft passing therethrough.
  • the first and second parts have adjacent facing surfaces which are respectively coaxial with the shaft, .the iirst part surface having a first annular groove formed therein coaxial with the shaft and the second part surface having a second groove yformed therein coaxial with the shaft and forming part of an annulus, the grooves being concentric and mutually defining a cavity.
  • the rst part has an opening therein communicating with the cavity and force transferring means are positioned in the cavity having one end engaging one end of the second groove ⁇ and its other end facing the opening in the fu'st part.
  • Adjustable means are provided in the opening and having a portion extending into the cavity and engaging the other end of the force transferring means whereby force exerted on the other end of the force transferring means is applied to the one and of the second groove thereby tending to rotate the second part with respect to the rst part and in turn causing the splined portions to engage the sha-ft in order to prevent rotational movement of the shaft with respect to the device.
  • FIG. 2 is a fragmentary cross-sectional view illustrating the adjustable splined pinion of my invention
  • FIG. 3 is a top view of my adjustable splined pinion taken along the line 3-3 of FIG. 2;
  • FIG. 4 is a cross-sectional view taken along line 4-4 of FIG. 2;
  • AFIG. 5 is a cross-sectional view ⁇ taken along the line 5 5 of FIG. 2;
  • FIG. 6 is -a cross-sectional view taken along the line 6-6 of fFIG. 2;
  • Winding head 10 having conventional wire dispensing needles 12 extending therefrom.
  • Winding head 1G is carried 'by a splined shaft 14 Vthrough which wire 16 is fed for dispensing through ⁇ the needles 12 and into the slots of an internally slotted dynamoelectric machine stator core member (not shown) as winding head 10 is reciprocally moved through the stator bore.
  • rl ⁇ he reciprocal motion is imparted yto splined shaft 14 and winding head 10 by means of a drive shaft 18, carrying a crank 20 and pitman 22 pivotally connected to crank 20 and to the splined shaft as at 24.
  • crank 20 and pitman 22 will impart linear reciprocal motion to the winding head 10 and splined shaft 14.
  • Winding head lti and splined shaft 14 are rotated at the ends of their reciprocal stroke, respectively, by means of an internally splined pinion, generally identiied at 26, which guides the splined shaft 14 in its reciprocal motion and which imparts rotary motion thereto.
  • a barrel cam 2S is provided mounted on shaft 18 and rotated therewith and having a 'cam slot 'Sil formed therein.
  • a cam follower 32 rides inthe cam slot 30 and is carried by arm 34 pivoted as at 36. Arm 34 is in turned pivotally connected ⁇ at 138 to rack 40 which engages teeth 42 of splined pinion 26.
  • Splined pinion 26 has journal surfaces 44 and ⁇ i6 formed thereon respectively journaled in bearing elements 48 and 50 which are secured to the vinding apparatus.
  • adjustable splined pinion 26 comprises two relatively rotatable splined sections 52 and 54.
  • Section 52 is elongated and has a cylindrical pocket extending inwardly from its end 56 with its side wall 58 ⁇ coaxial with and radially spaced from splined shaft 14 and with its 'bottom Wall 60 extending radially outwardly ⁇ from shaft 14.
  • Internal splines o2 are formed on member 52 for guiding shaft 14 for reciprocal movement in the direction shown by the arrows 64, the splines 62 communicating with the bottom wall 66 of the pocket and with an elongated opening 66 extending to the other end 68 of member 52 which coaxially ⁇ surrounds ⁇ shaft 14.
  • Pinion teeth 42 are formed on the exterior of member 52 in order to impart the requisite rotational motion thereto and in turn to yshaft 14.
  • Member 52 is preferably formed of a good bearing material, such as bronze in order to prevent vseizing at high speed, and thus, steel journal sleeves 44 land 45 are pressed thereover in order rotatably to support the member 52.
  • Splined section 54 is cylindrical in configuration and Y*is journaledwithin the pocket mem'ber 52 so as to be relatively rotatable with respect to the member 52; splined section 54 'has its cylindrical side wall 7i? in sliding engagement with side wall S of .the pocket ⁇ and its bottom ywall 72 likewise in sliding engagement with bot-
  • the outer periphery of member 52 adjacent end 56 is v enlarged, as at 76, and an annular groove 78 of semicircular cross-section is formed in side Wall 58 of the pocket member 52, as shown.
  • Another groove 8b of semioircular cross-section and dening part of an annulus is formed in the outer side wall 7'9 of splined section S4, the grooves 78 and t?
  • a boss or projection S4 is formed on one side of the enlarged portion 76 of member 52 and has an opening 86 formed therein ltangentially communicating with the cavity 82 and coplanar therewith. Opening 86 is internally threaded to receive threaded plug SS which has ⁇ a projection 9% formed thereon extending into the cavity S2; plug 88 is provided with a socket 92 whereby the plug with its projection 90 may be threaded into and out of .opening S6.
  • a chain of balls 94 is Aprovided respectivelyV abutting and substantially filling cavi-ty 82, .one end ball 96 engaging :the end 9S of slot 80 in splined Vsection 54, and the other end ball 100 'facing the ⁇ opening 86, but being nevertheless outside of the opening 86 so that 4an equator of ball 100 continuously engages the wall of cavity 82.
  • Projection 90 of plug 88 engages the end ball b thus biasing the balls 94 into abutting relationship so that the end ball 96 ⁇ engages end 98 of groovetl.
  • the close manufacturing tolerances previously required in cutting the spline in the pinion and on the shaft are no Ilonger necessary since the ability to adjust the relative rotational positions of splined sections 52 and 54 permits initial vadjustment to eliminategall back-lash in the splined shaft 14.
  • the splined members 52 Iand 54 may be formed of material having good bear-ingproperties rather than of steel and thus my adjustable splined pinion can accommodate higher linear speeds of shaft i4 without seizing.
  • said rst part surface having a rst annular groove formed therein coaxial with said shaft, said second part surface having a second groove formed therein coaxial with said shaft and forming part of an annulus, said grooves being concentric and mutually defining a cavity, said rst part having .an opening therein communicating with said cavity, force transfer means in said cavity having one end engaging one end of said second groove and its other end facing said opening, and adjustable means in saidopening and having a portion extending into said cavity and engaging the other end of said force transfer means whereby force exerted on said other end of said force transfer means is applied to said one end of said second groove thereby tending to rotate said second part with respect to said r'st part causing said splined portions to engage said shaft to prevent rotatable movement thereof lwith respect to said device.
