“…In work [12], how to manufacture isoelastic dental implant materials with optimized surface properties is reported, and in [13] how to provide complete control over the microarchitecture of porous titanium implants is described. Depending on the application, gear transmissions should be characterized by suitable geometric and kinematic accuracy, as well as durability [14]. The structure of DLMS-fabricated gears is porous, which enables their impregnation by grease or the application of a layer improving the gear's strength [14].…”

This paper presents findings concerning the accuracy of the geometry of cylindrical spur gear teeth manufactured with the direct metal laser sintering (DMLS) method. In addition, the results of the evaluation of the tooth surface geometric structure are presented in the form of selected two-dimensional and three-dimensional surface roughness parameters. An analysis of the accuracy of the fabricated gear teeth was performed after gear sand-blasting and gear tooth milling processes. Surface roughness was measured before and after sand-blasting and gear tooth milling. The test gear wheel was manufactured from GP1 high-chromium stainless steel on an EOS M270 machine.

“…Localization of the bearing contact in spiral and hypoid gear drives is a common practice and there are mainly two face-hobbing systems that provide different ways to localize the bearing contact: System (1) is based on the application of a single head-cutter where the cutter tilt angle is used to modify the curvatures of the tooth surfaces, whereas System (2) is based on the application of a dual head-cutter where two separate rotating centers are considered and lead crowning is achieved due to the different cutter radii of inner and outer blades. Processes Spirac c , Spiroflex c and CycloCut c belong to System (1) whereas Cyclo-palloid c belongs to System (2) [1,2]. While the first system provides more simplicity for machine construction, the second system allows to pay attention just to the head-cutter to localize the bearing contact, regardless of the rest of machine-tool settings that are calculated according to the cutter radii.…”

Analytical determination of basic machine-tool settings for generation of spiral bevel gears and compensation of errors of alignment in the cyclo-palloid system, International Journal of Mechanical Sciences, http://dx.doi.org/10.1016Sciences, http://dx.doi.org/10. /j.ijmecsci.2016 This is a PDF file of an unedited manuscript that has been accepted for publication.

AbstractA model for computerized generation of spiral bevel gears in the cyclo-palloid system is proposed. Kinematic conditions of cutting are investigated for tooth thickness and backlash control. Basic machine-tool settings are analytically determined from basic transmission data with the aim of getting favorable conditions of meshing and contact when the gear drive is transmitting a nominal or design load and shaft deflections occur. Errors of alignment of the gear drive due to shaft deflections are considered as input data in the analytical procedure. The proposed procedure is tested through tooth contact and backlash analyses of the gear drive. Several numerical examples are presented.

Abstract. Hyperboloid gear drives with face mating gears are used to transform rotations between shafts with non-parallel and non-intersecting axes. A special case of these transmissions are Spiroid 1 and Helicon gear drives. The classical gear drives of this type are the Archimedean ones. The objective of this study are hyperboloid gear drives with face meshing, when the pinion possesses threads of conic convolute, Archimedean and involute types, or the pinion has threads of cylindrical convolute, Archimedean and involute types. For simplicity, all three types transmissions with face mating gears and a conic pinion are titled Spiroid and all three types transmissions with face mating gears and a cylindrical pinion are titled Helicon.Principles of the mathematical modelling of tooth contact synthesis are discussed in this study. The presented research shows that the synthesis is realized by application of two mathematical models: pitch contact point and mesh region models. Two approaches for synthesis of the gear drives in accordance with Olivier's principles are illustrated. The algorithms and computer programs for optimization synthesis and design of the studied hyperboloid gear drives are presented.
