摘要： A method wherein by reducing the amount of current, and therefore torque, to the linear servo motor (50) and/or rotary servo motor (52) of a loader mechanism (9), the loader mechanism is operable for determining proper workpiece positioning in a machine tool such as a gear manufacturing machine, particularly a machine (4) for manufacturing bevel and hypoid gears.

摘要： A gear roll-testing method directed to the analysis and display of gear-set performance data, including motion transmission error, as acquired on gear-set rolling testers or gear-box test fixtures and includes the analysis and visualization of this data in the time-domain, frequency domain, and hybrids thereof. The invention further includes fundamental improvements in core signal processing, analytical and signal processing sequences that allow the data to be explored in more insightful ways, methods of visualizing and reporting the data and results, and a man-machine user-interface paradigm to provide these functions and features with greater flexibility and utility.

摘要： 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.

摘要： 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.

摘要： A method and cutting tool for producing spiral toothed face couplings whereby a two-part cutter and a two-part machine tool spindle are not needed. The process includes a set-over between the cutting of convex (41) and concave (43) tooth surfaces and the tool (59) comprises inside and outside cutting blades positioned in a single cutter head blade slot (57) and separated from one another by a blade spacing angle (51).

摘要： A method of machining a bevel gear (22) having teeth with a pitch angle greater than 90 degrees comprising providing at least one tool (42, 44) rotatable about a tool axis with the tool comprising a disc-shaped body (43) having a periphery (49) and at least one stock removing surface (45, 47) arranged about the periphery. The tool is rotated and fed relative to the gear to effect machining of at least one tooth surface wherein the machining is carried out in a non-generating manner.

摘要： A motion which creates an end relief and which is integrated into the plunging cycle of non-generated bevel gears. The tool, after feeding to the correct tooth forming position in case of non-generated gears, is swung sideways out of cutting or grinding contact with the slot instead of along a withdraw path which is identical to the plunge path but opposite in direction.
