Definitions
- the invention relates to a bill-shaped, rotating tool for profiling cylindrical grinding worms according to the preamble of claim 1.
- a bill-shaped, rotating tool for profiling cylindrical grinding worms according to the preamble of claim 1.
- Such a tool is known from DE-A-20 10 526.
- a precise, but slow and cumbersome process is to create the screw profile by means of ground shape diamonds. These are used in a similar way to turning steels and the procedure for this type of profiling can be compared to cutting a thread on a lathe. Because this process is slow and because the form diamond tools are very delicate and uneconomical, it is rarely used today.
- Another possibility is referred to as the crushing process, in which a press roller shaped according to the profile cross section is pressed with great force against the slowly rotating grinding worm without its own drive.
- the blunted grains are broken out of the disk matrix and the screw profile assumes the shape of the press roller profile if the crushing time is long enough.
- This process has the advantage that it can be used to produce profile shapes with rounded corners and feet or with other special contours without great difficulty.
- a disadvantage is the relatively large wear of the press roll during profiling and the very large forces that arise during the crushing process.
- the profiling roller Similar and also known for a long time is the profiling roller, which is shaped according to the grinding worm profile and coated with hard material grains, but in contrast to the press roller is brought to high speed by a motor drive and thus produces the worm profile by an actual cutting process with relatively low forces.
- the disadvantage of this method is that the very high accuracy that must be required from the profiling roller can hardly be achieved.
- the hard body cannot be coated with the required quality.
- the grinding worm 1 is used to profile a cylindrical grinding worm 1 for grinding spur gears in the continuous rolling process.
- the grinding worm 1 has a helical groove 2 with a first flank 3 for grinding one tooth flank, a second flank 4 for grinding the other tooth flank, and a foot section 5 and a head section 6.
- the foot section 5 consists of one each on the flanks 3, 4 About a convex edge 7 adjoining, radially directed sections 8, 9 and an approximately cylindrical section 10.
- the approximately cylindrical head section 6 merges on both sides with a curve and a convex edge 11 into the flanks 3, 4 (Fig. 2). When grinding the associated gear, the foot section 5 is not in engagement with the gear.
- the profiling tool consists of two rotationally symmetrical disks 15, 16, which are each clamped on a separate, motor-driven spindle 17, 18.
- the spindle 18 is on a cross slide 19 mounted and thus axially and radially adjustable relative to the spindle 17.
- the bearing of the spindle 17 and the cross slide 19, not shown, are mounted on a profiling slide, not shown, which moves to produce the helical groove 2 depending on the rotational movement of the grinding worm 1 back and forth parallel to the latter.
- the disk 15 is used to profile the flanks 3, 4 and has an adapted surface 21, 22 for each.
- the surfaces 21, 22 are longer in axial section than the flanks 3, 4 and each protrude over the edges 7 when engaged with the grinding worm 1 , 11 out.
- the surfaces 21, 22 are covered with hard granules, e.g. with grains of diamond or cubic boron nitride. Because they have no sharp curvatures in the axial section, they can be lapped because the lapping disks can run out laterally, so that the flanks 3, 4 of the grinding worm 1 can be profiled with very high accuracy.
- the second disk 16 has a section 25 covered with hard material grains for profiling the foot section 5.
- the section 25 consists of two flat sections 26, 27 and a cylindrical section 28.
- the cylindrical section 28 alone would suffice; but it is advantageous to also cover pages 26, 27 for better edge retention.
- the disk 16 each has an approximately cylindrical section 31, 32 covered with hard material grains for profiling each about half of the head section 6.
- Each section 31, 32 merges via a rounding 33 into a conical section 34, which is slightly smaller Has opening angle as the flanks 3, 4 adjacent to the edge 11 (Fig. 2). Since the foot and head sections 5, 6 of the grinding worm 1 are not subject to high accuracy requirements, the parts 25, 31, 32 do not need to be lapped.
- the cross slide 19 aligns the second disk 16 with respect to the first disk 15 such that both the flanks 3, 4 and the foot and head sections 5, 6 are simultaneously profiled in the same pass. This enables the profiling of the grinding worm 1 to be automated easily.
- the disk 15 can also be composed of two partial disks and a spacer.
- the disc can then be adapted to other widths of the groove 2 by changing the spacer.
- An analogous solution is also shown in FIG. 3 for the second disk 16 ', which here is composed of three partial disks 38, 39, 40 and two spacer disks 41.
- the middle graduated disk 40 can, as indicated by dashed lines is divided by a parting plane 42 which is slightly inclined to the radial direction. The thickness of this indexing disk 40 can also be adjusted by means of inserts 43. Because of the inclined parting plane 42, the circumferential sections forming the section 28 overlap when the disk 16 'is rotated.
- the two disks 46, 47 are constructed identically and each have a hard-grain-coated surface 48, 49 for profiling the flanks 3, 4.
- the surface 48 for profiling the right flank 4 is closed on the outer circumference by a hard-grain-coated part 50 for profiling the left half of the Foot section 5, ie of section 8 and the adjoining half of section 10.
- the second disk 47 has a corresponding section 51 for profiling the other half of the foot section 5.
- the disks 46, 47 each have a section 52, 53 for processing half of the head sections 6 the two disks 46, 47 can be clamped on a common, driven spindle or, if an individual, small adjustment possibility of the two disks against one another is desired, can each be clamped on a separate, individually driven spindle.
- this disk it is indicated by dashed lines that this disk can also be constructed from a plurality of dividing disks and spacer disks.
