Definitions

  • the present invention relates to av device for maintaining the form and position of i the working surface of the grinding disk in grinding machines.
  • the object of the inven t1 tion is to enable the operator to determine the momentwhen the working surface of the grinding disk takes up a predetermined position, to maintain it in such position and to maintain the form of the'working surface w of the grindingdisk.
  • the invention consists, essentially, in the grinding machine being provided with a. feed device for the grinding disk, said feed device working continuouslyor at definite intervals, and also 145 with a rotary dressing or abrading member for the working surface of the grinding disk.
  • the working surface of the dressing member, or the part thereof engaging the working surface of the grinding disk is suitably maintained in a predetermined position dependent on the final form. or dimensions.
  • Fig. 1 is a longitudinal section of a device according to this invention.
  • Fig. 2 is a cross-section on line AB of Fig. 1.
  • Figs. 3 and 4 show an application of the device in grinding gear wheels.
  • FIG. 1 designates a frame on which a slide 2 is movable, said. slide forming a bearing for the grinding disk.
  • a dressing or abrading member 15 the working surface 16 of which, in the form of embodiment shown, is annular in shape, and plane.
  • the dressing member 15 is kept pressed, by a spring 17 placed around the shaft 14, against contact devices illustrated in the formof rollers 18 rotatably journaled in'a slide 19 adjustably mounted in the frame 1 and secured in place by some suitable means, as a screw 19 as shown.
  • Said slide serves at the.same time as a bearing for'the shaft 14, throughthe medium of'a sleevelike prolongation 20 of the member 15.
  • the position of the working surface 16 of the 'member 15 is this fully determined by the rollers 18, and by adjusting the slide 19 with the rollers 18 in such manner that the tangent plane of the rollers (corresponding to line A--B of Fig.
  • FIGs. 3 and 4 an application of the arrangement .for grinding gear wheels according to the rolling principle is schematically illustrated.
  • 3 designating. as in Figs. 1 and 2..
  • the grinding disk fed with the speed hereinbefore mentioned. said disk having here the shape of a plate, and 15 designating the rotary dressing or abrading member fixed in position.
  • the working surface 22 of the grinding disk. the position of which is fully determined. as hereinbefore' mentioned. by the working surface 16 of the dressing member. represents a tooth side in an imagined generating rack 23. It is essential to maintain the form of the working surface of the grinding disk, which, in the illustrated form, is plane.
  • the peripheral speed is greater at the outer circumference of the annular working surface 22 than at the inner circumference
  • the wear of the. grinding disk in grinding certain forms as for instance a tooth profile. would, if no measures to the contrary were taken, be greater at the outer circumference than at the inner circumference. i. e. the working surface of the grinding disk would not maintain its plane form but would obtain a curved profile.
  • the dressing or abrarding member 15 is, therefore, to be arranged in such manner as to exert a greater abrading action at the inner circumference of the surface 22 of the grinding disk than at the outer circumference.
  • the working surface of the dressing memher need not be plane since it is. obviously, dependent on the form to be given to the working surfaces of the grinding disk. It is also obvious that if desired,-the feed of the grinding disk need not be continuous.
  • An arrangement for maintaining the form and position of the working surface of the grinding disk in grinding machines characterized by an annular grinding disk, a feed device for the grinding disk and by a rotary annular dressing or abrading member with which the annular working surface of i the grinding disk is maintained in engagement.
  • An arrangement according to claim 1 characterized by the grinding disk being automatically feed forward more than the wear of the grinding disk caused by the work piece alone but equal or substantially equal grinding disk as to exert a less abrading action at and near the outer circumference of the grinding disk than at places located gea'er to the axis of rotation of the grinding 6.
  • a rotary grinding member a rotary dressing member adapted to act on the working surface of the grinding member
  • a contact device normally in engagement with the working surface of the dressing member and adjustable to position said surface at a predetermined relation to the final surface of the work to be ground
  • means for maintaining the engagement of the working surface of the dressing member with said contact device means for feeding the grinding member to engage the Working surface of the dressing member and to act on the work.
  • a rotary grinding member a rotary dressing member adapted to act on the working surface of the grinding member, a series of contact rollers normally in engagement with the working surface of the dressing member and adjustable to position said surface at a predetermined relation to the final surface of the work to be ground, means for maintaining the engagement of the working surface of the dressing member with said contact rollers, and means for feeding the grinding member to engage the working surface of the dressing member and to act on the work.
  • a rotary grinding member a rotary dressing member adapted to act on the working surface of the grinding member, a contact device engaged by the working surface of the dressing member and adjustable to osition said surface at a predetermined re ation to the final surface of the work to be ground, means for yieldingly maintaining the engagement of the working surface of the dressing member with said contact device, and means for feeding the grinding member to enga e the working I surface of the dressing mem on the work.
  • a rotary grinding memher adapted to act on the working surface of the grinding member
  • a series of contact rollers engaged by the working surface of the dressing member and'adjustable to position said surface at a predetermined relation to the final surface of the work to be round
  • means for yieldingly maintaining the engagement of the dressing member With said contact rollers and means for feeding the grinding member to engage the working surface of the dressing member and to act on the work.
