A new method for generation of spiral bevel gears is proposed. The main features of this method are as follows: (i) the gear tooth surfaces are conjugated and can transform rotation with zero transmission errors; (ii) the tooth bearing contact is localized; (iii) the center of the instantaneous contact ellipse moves in a plane that has a fixed orientation; (iv) the contact normal performs in the process of meshing a parallel motion; (v) the motion of the contact ellipse provides improved conditions of lubrication; and (vi) the gears can be manufactured by use of Gleason's equipment.

A new approach for design, generation, and computerized simulation of meshing and contact of face-milled, formate cut spiral bevel gears is presented. The purpose is to develop a low noise, stabilized bearing contact for this type of gear drives. The approach proposed is based on application of three procedures that permit in sequence, to provide a longitudinally directed bearing contact, a predesigned parabolic function of transmission errors and limit the shift of bearing contact caused by errors of alignment. The theory developed is illustrated with an example of design and computation.

An integrated tooth contact analysis (TCA) computer program for the simulation of meshing and contact of gear drives that calculates transmission errors and shift of hearing contact for misaligned gear drives has been developed. The computer program combines numerical solutions for the problems above and their graphical interpretation. The program is applicable for various gear drives but requires derivation of tooth surface equations for each gear drive type. The computer program represents a set of integrated operations such as the development of required algorithms database storage copying, deleting printing and design correction from the database. The computer program uses the Java programming language. An example for a spiral bevel gear drive is presented.

A new approach for determination of machine-tool settings for spiral bevel gears is proposed. The proposed settings provide a predesigned parabolic function of transmission errors and the desired location and orientation of the bearing contact. The predesigned parabolic function of transmission errors is able to absorb piece-wise linear functions of transmission errors that are caused by the gear misalignment and reduce gear noise. The gears are face-milled by head cutters with conical surfaces or surfaces of revolution. A computer program for simulation of meshing, bearing contact and determination of transmission errors for misaligned gear has been developed.

A computer aided method for tooth contact analysis was developed and applied. Optimal machine-tool settings for spiral bevel gears are proposed and when applied indicated that kinematic errors can be minimized while maintaining a desirable bearing contact. The effect of misalignment for circular arc helical gears was investigated and the results indicated that directed pinion refinishing can compensate the kinematic error due to misalignment. (Author).

A new method for design and generation of spiral bevel gears of uniform tooth depth with localized bearing contact and low level of transmission errors is considered. The main features of the proposed approach are as follows: (1) The localization of the bearing contact is achieved by the mismatch of the generating surfaces. The bearing contact may be provided in the longitudinal direction, or in the direction across the surface; and (2) The low level of transmission errors is achieved due to application of nonlinear relations between the motions of the gear and the gear head-cutter. Such relations may be provided by application of a CNC machine. The generation of the pinion is based on application of linear relations between the motions of the tool and the pinion being generated. The relations described above permit a parabolic function of transmission errors to be obtained that is able to absorb almost linear functions caused by errors of gear alignment. A computer code has been written for the meshing and contact of the spiral bevel gears with the proposed geometry. The effect of misalignment on the proposed geometry has also been determined. Numerical examples for illustration of the proposed theory have been provided. Litvin, F. L. and Zhao, X. Glenn Research Center...

This is the first book to offer a complete presentation of bevel gears. An expert team of authors highlights the areas of application for these machine elements and presents the geometrical features of bevel gears as well as the various gear cutting processes based on gear cutting theory. The aspect of three-dimensional gearing is assessed in detail in terms of flank design, load capacity and noise behavior. A representation of production processes with the required technologies provides a knowledge base on which sound decisions can be based. The authors offer a thorough introduction to the complex world of bevel gears and present the rapid advances of these machine elements in a detailed, comprehensible manner. This book addresses design engineers in mechanical engineering and vehicle manufacturing, as well as producers of bevel gears and students in mechanical engineering.
