Topland chamfering of gears
11090744 · 2021-08-17 · ·

A method wherein a cutting or grinding chamfering tool (25) is guided along the face width of a gear (12, 23, 52) through one tooth slot (8) (e.g. from heel to toe) while it contacts the topland corners (10, 1 1) of the respective concave and convex tooth flanks of adjacent teeth (2, 4). The tool moves to an index position, the gear is indexed to the next tooth slot position and the tool moves through the tooth slot (e.g. from the toe to the heel). The cycle is repeated until all topland corners are chamfered.

METHOD FOR GRINDING A BEVEL GEAR
20210078090 · 2021-03-18 ·

Method for grinding a bevel gear, comprising the method steps of clamping a bevel gear (14) to be ground on a workpiece spindle (12) of a bevel gear grinding machine (2); first grinding of the tooth flanks (16, 18) of the bevel gear (14) with a first grinding tool (6), wherein the first grinding tool (6) is arranged on a first tool spindle (4) of the bevel gear grinding machine (2); fine grinding of the tooth flanks (16, 18) of the bevel gear (14) with a second grinding tool (10), wherein the second grinding tool (10) is arranged on a second tool spindle (8) of the bevel gear grinding machine (2).

Mono-blade bevel gear cutting tool

A gear cutting tool wherein each cutting blade group includes two differently positioned but identical cutting blades (41, 40) such as an one outside and one inside blade. The inventive blade arrangement only requires a single type of blade (30) in order to simultaneously cut the convex and the concave tooth flanks of a gear as well as the root fillet and root bottom portions of tooth slots. The cutter system allows radial adjustment of the outside cutting blade and the inside cutting blade independently of one another. Additionally, inside and outside cutting blades may be exchanged with one another.

Method and apparatus for loading and positioning a workpiece on a gear manufacturing machine

A method wherein a first workpiece (2, 40) is loaded to a spindle (30) of a workpiece processing machine with the first toothed workpiece having a predetermined design and being in a predetermined rotational load position. The first toothed workpiece is stock-divided and a machining position is determined based on the stock-dividing. The first toothed workpiece is rotationally adjusted to the machining position. The teeth (3, 42) of the first toothed workpiece are then machined and the first workpiece is removed from the spindle. A second toothed workpiece is loaded to the spindle of the workpiece processing machine. The second toothed workpiece has the same predetermined design and is in the same predetermined rotational load position as the first toothed workpiece. The second toothed workpiece is rotationally adjusted from the predetermined rotational load position to the machining position by the same adjustment amount as the first toothed workpiece. The second toothed workpiece is machined and then removed from the machine spindle. The process as performed for the second toothed workpiece can be repeated for subsequent workpieces having the same design and being in the same rotational load position as the first and second workpieces. For the second and subsequent toothed workpieces, the step of determining the rotary position of the teeth is not carried out.
