Abstract

745,251. Rolling helical. grooves. CARRIER CORPORATION. July 29, 1953 [July 31, 1952], No. 21080/53. Class 83 (4). In a machine for rolling helical fins 41, Fig. 5, on a tube 19 a plurality of skewed forming rolls 21, Fig. 2, are circumferentially spaced around the tube 19 on arbors 35 detachably connected to aligned skewed drive shafts 29 at one end, the other end being mounted in bearing blocks 53 detachably secured in the machine housing 7 and slidingly removable therefrom. The bearing blocks 53 are mounted in the recesses 57 of a trefoil shaped opening in the housing 7 and are held in position by bolts 59 engaging slots 62 in the blocks 53. The inner ends 37 of the arbors 35 rotate in bearings 33 and are cup-shaped and internally splined for driving engagement with splines on the drive shafts 29. Bolts 65 passing through the arbors and screwed into recesses 67 on the drive shafts 29 clamp the rolls 21 on the arbors through sleeves 45. Each roll 21 comprises a series of axially spaced groove forming discs 39. The drive shafts are driven through gears 27 from a central skewed tooth gear 23 on a guide tube 9 mounted on bearings 11 and rotated by a beltdriven wheel 13. Specifications 651,774 and 651,829 are referred to.
