This book was released on 2018-07-24 with total page 218 pages. Available in PDF, EPUB and Kindle. Book excerpt: 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.

This book was released on 2001 with total page 60 pages. Available in PDF, EPUB and Kindle. Book excerpt: 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.

Available in PDF, EPUB and Kindle. Book excerpt: This book gathers the proceedings of the 16th IFToMM World Congress, which was held in Tokyo, Japan, on November 5–10, 2023. Having been organized every four years since 1965, the Congress represents the world’s largest scientific event on mechanism and machine science (MMS). The contributions cover an extremely diverse range of topics, including biomechanical engineering, computational kinematics, design methodologies, dynamics of machinery, multibody dynamics, gearing and transmissions, history of MMS, linkage and mechanical controls, robotics and mechatronics, micro-mechanisms, reliability of machines and mechanisms, rotor dynamics, standardization of terminology, sustainable energy systems, transportation machinery, tribology and vibration. Selected by means of a rigorous international peer-review process, they highlight numerous exciting advances and ideas that will spur novel research directions and foster new multidisciplinary collaborations.

This book was released on 2018-07-08 with total page 82 pages. Available in PDF, EPUB and Kindle. Book excerpt: 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 book was released on 1999 with total page 26 pages. Available in PDF, EPUB and Kindle. Book excerpt: 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.

Download or read book Generation of Spiral Bevel Gears with Conjugate Tooth Surfaces and Tooth Contact Analysis written by Faydor L. Litvin and published by . This book was released on 1987 with total page 134 pages. Available in PDF, EPUB and Kindle. Book excerpt: 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.
