23 Method for fabricating bevel and hypoid gear pairs US641387 1984-08-16 US4611956A 1986-09-16 Erich Kotthaus
A method of manufacturing bevel and hypoid gear pairs according to an imaginary mating gear cutting process. The tooth spaces are cut by means of a face-mill cutter head rotating about an axis of rotation. In order to overcome heretofore prevailing limitations on the gear diameter, cone angle and shaft angle of gear pairs, either the gear or the cutter head performs an arcuate generating movement about a generating axis in order to produce one of the gears, whereby a machining axis is adjusted relative to the generating axis in accordance with the position of the axes of both gears of the gear pair. In one advantageous embodiment, the same machining axis adjustment is also employed for fabricating the mating, non-generated gear.
24 Bevolute gear system US880368 1978-02-23 US4238970A 1980-12-16 Willis M. Carter
The present invention relates to a bevolute gearing system which transmits torque between non-intersecting shafts at right angles to each other. The bevolute gear system includes a pinion gear which is flat and in one plane. The pinion gear is designed to include teeth which are shaped in the form of an involute spiral. The bevolute gear system includes a second gear which is also designed to include teeth which are shaped in the form of an involute spiral. The second gear is mounted on a non-intersecting axis at a right angle to the axis of the pinion gear. The bevolute gearing system of the present invention reduces the thrust loads to negligible values for the bearings of both the pinion gear and the second gear. In addition, higher mechanical efficiencies, wider tolerances on alignment of the gears, interchangeability between the gear and the pinions to produce different ratios and a substantially eliminated gear noise are a few of the many advantages disclosed in the present invention.

26 Splined member and process for manufacturing a splined member by shaping and milling EP11183461.0 2011-09-30 EP2520388A2 2012-11-07 Phebus, Dan E.; Hayward, William H.

By combining shaping and milling actions, or smilling, the cutting tool (536) can move (539) through the entire usable portion of the spline and machine a tool relief (505R) into the face of the adjacent feature such as a shoulder (532) before retracting (540), reversing direction (541), and repeating the cycle (542,539,540,541). The smilling apparatus and manufacturing method eliminates the need for an annular spline relief and the full length of spline engagement can be utilized for strength. The effective width of the spline connection apparatus manufactured by the smilling process conserves space and increases the load carrying capability of the spline connection. Independent claims relate to the male and female parts of the spline connections as well as the processes of manufacturing these parts.

38 Method and apparatus for lapping gears US10996577 2004-11-23 US07153183B2 2006-12-26 Gary E. Kopp; Richard W. Locker; Bogdan F. Muzyk; Medhat Said
A method for lapping the gears of a gear set as well as a gear lapping system. The gear set generally includes a first gear in meshed engagement with a second gear, each of the first and second gears having a plurality of gear teeth each with drive and coast flank surfaces. The method includes the steps of lapping the gear set by rotating the first gear in a first direction while the first gear is in mesh with the second gear. The method further includes sensing the vibrations occurring in the gear mesh during rotation and controlling the step of lapping based on the sensed vibrations. The gear lapping system includes an automated lapping machine that is adapted to lap the gear set including a ring gear and a pinion gear. The automated lapping machine is adapted to lap the gear set by rotating at least one of the ring and pinion gears while in mesh, in the presence of a lapping compound, and while translating the gear mesh back and forth across the gear flank surfaces for a plurality of cycles. A vibration sensor is operably coupled to the automated lapping machine and senses the amplitude of vibration and energy occurring in the gear mesh during each of the plurality of cycles. This sensor produces a vibration output signal that is proportional to the amplitude of the vibration energy. An automated controller is adapted to receive the vibration output signal as well as to calculate and transmit a control command signal to the automated lapping machine based on the amplitude of the vibration energy.
39 Bevel gear pair US09644625 2000-08-23 US06481307B1 2002-11-19 Diether Klingelnberg
In a bevel gear pair including a first gear having a plurality of first gear teeth, each defined at least in part by a tooth route and concave and convex flank surfaces, the concave and convex flank surfaces each define a first surface structure formed by grinding. This first surface structure is in turn defined by a plurality of microstriations extending diagonally across the convex and concave flank surfaces. A second gear also includes a plurality of gear teeth adapted to mesh with the gear teeth of the first gear. Each of the second gear teeth is also defined in part by a tooth route and concave and convex flank surfaces. The concave and convex flank surfaces of the second gear define a second surface structure formed by grinding followed by honing. This second surface structure includes a plurality of microstriations; however, unlike the microstriations of the first surface structure, these are parallel to the route of each of the second gear teeth. This allows the first and second gears to be produced in unmatched pairs, yet be operated together at noise levels approaching those of matched lapped bevel gear pairs.
40 Method of machining gears US09444682 1999-11-22 US06390893B1 2002-05-21 Hermann J. Stadtfeld; Uwe Gaiser
A method of machining at least one tooth flank of a gear with a finishing tool. The method comprises rotating the finishing tool, such as a grinding tool, and bringing the tool and the tooth flank into contact. Relative movement between the tool and the gear is provided to traverse the tool across the tooth flank along a path whereby the path produces a tooth flank geometry of a form which, when brought into mesh with a mating tooth flank to form a tooth pair under no load or light load, provides a motion graph curve that intersects, at least two times, a motion graph curve of at least one of an immediately preceding tooth pair and an immediately following tooth pair. The motion graph curve of the tooth pair describes contact between respective tooth flanks of said tooth pair from an initial entrance into mesh to a final exit from mesh as being over a gear rotation amount of greater than 1.0 pitch and preferably, about 1.5 pitch to about 3.0 pitch.
