Abstract
A contouring tool for grinding cylindrical worm profiles includes two disks 46, 47 having hard grain coated surfaces 48, 49 for contouring the opposing flanks 3, 4 of the grinding worm 1. Hard grain coated parts 50, 52, which are provided for contouring the root and crest sections 5, 6 that directly adjoin the flanks 3 to be dressed with one disk 47, are mounted on the other disk 46. The surfaces 48, 49 can thus be lapped. A grinding worm 1 can be contoured in one operation with this tool.
Claims10
A rotating contouring tool for profiling in a single operation a cylindrical grinding worm (1) which is designed for grinding gear wheels in a continuous gear cutting process and which has a first grinding worm flank (3) for dressing a tooth flank, a second grinding worm flank (4) opposite the first flank for dressing an opposing tooth flank, a root section (5) and a crown section (6), said tool comprising:
- two simultaneously rotatable disks (15, 16;
- 46, 47), one (15;
- 47) of said disks having at least one first surface (21, 49) for contouring only the first grinding worm flank (3), and the other disk (16;
- 46) having additional surfaces (25, 31;
- 50, 52) for simultaneously contouring only the grinding worm root and crown sections, said grinding worm root and crown sections directly adjoining the first grinding worm flank.
A tool for profiling in one operation a cylindrical grinding worm (1), in turn used to grind gear wheels, said tool comprising:
- (a) a first rotatable disk (15) having radially converging side surfaces (21, 22) coated with hard abrasive particles for contouring opposite flanks (3, 4) of a helical groove (2) in said worm, and
- (b) a second simultaneously rotatable disk (16) disposed axially parallel to and spaced from the first disk, said second disk having:
- (1) a rectangularly sectioned radially outermost tip portion (25) coated with hard abrasive particles for contouring a root portion (5) of the groove, and
- (2) a pair of radially inner, generally cylindrical surfaces (31, 32) flanking said outermost surface, having outturned facing edges (34), and coated with hard abrasive particles for cooperatively contouring a crest portion (6) of the groove.
A tool for profiling in one operation a cylindrical grinding worm (1), in turn used to grind gear wheels, said tool comprising:
- (a) a first rotatable disk (46) having:
- (1) a radially inclined first side surface (48) coated with hard abrasive particles for contouring a first flank (4) of a helical groove (2) in said worm,
- (2) a radially outermost L-sectioned tip portion (50) adjoining said first side surface and coated with hard abrasive particles for contouring approximately one-half of a root portion (5) of the groove, and
- (3) a radially inner, generally cylindrical surface (52) disposed opposite said first side surface, having an outturned inner edge, and coated with hard abrasive particles for contouring approximately one-half of a crest portion (6) of the groove, and
- (b) a second simultaneously rotatable disk (47) disposed axially parallel to and spaced from the first disk, said second disk having:
- (4) a radially inclined second side surface (49) coated with hard abrasive particles for contouring a second flank (3) of the groove,
- (5) a radially outermost L-sectioned tip portion (51) adjoining said second side surface and coated with hard abrasive particles for contouring approximately another one-half of the root portion of the groove, and
- (6) a radially inner, generally cylindrical surface (53) disposed opposite said second side surface, having an outturned inner edge, and coated with hard abrasive particles for contouring approximately another one-half of the crest portion of the groove.
