Abstract:

Digitized hypoid gear’s surface model, which is constructed by NURBS method, can set free the constraints of conventional processing technique in the process of designing and manufacturing hypoid gear. The digitalization of tooth surfaces of hypoid gears consists of three parts: building large gear’s NURBS model, calculating small tooth surface’s character parameters based on actual requirements and small tooth surface’s digitalization. The digitalization of tooth surfaces can be realized by machining simulation, and the key points are how to establish equations of cutter head and grids of gea

Crossed-axis helical gears and hypoid gears are two conventional crossed-axis power transmission devices. Helipoid gears, a novel gear proposed herein, possess the merits of the crossed-axis helical and hypoid gears. A mathematical model of the proposed helipoid gear cut by shapers is also derived according to the cutting mechanism and the theory of gearing.

Abstract:

The fundamental design of spiral bevel and hypoid gears is usually based on a local synthesis and a tooth contact analysis of the gear drive. Recently, however, several flank modification methodologies have been developed to reduce running noise and avoid edge contact in gear making, including modulation of tooth surfaces under predesigned transmission errors. This paper proposes such a flank modification methodology for face-hobbing spiral bevel and hypoid gears based on the ease-off topography of the gear drive.

Abstract:

In industrial or automotive dip lubricated gear drives, low oil levels may be used due to different design requirements or constraints. A variation of the sump oil level affects different working conditions of gears, such as the power loss, the heat generation, and the load-carrying capacity with respect to different types of damage. In particular, reduced oil levels decrease the scuffing load capacity of gears because of high bulk temperatures and reduced oil quantity in the gear mesh. Investigations were made in a back-to-back hypoid gear test rig to evaluate the influence of the bath oil le

Abstract:

In order to make the substituted circular arc generating lines be a series easily, based on the principles of cutting hypoid gears by generating-line method and the pinion generating lines substituting method, an optimization which the objective was to make the substituted circular arc generating lines radiuses of pinion be integers or approximate integers was proposed. The feasibility of this optimization method was verified by the calculating example of a pair of hypoid gears.

Abstract:

In this paper, the influence of the manufacturing parameters on the conditions of mixed elastohydrodynamic lubrication is investigated. On the basis of the obtained results, recommendations are formulated to improve the mixed EHL and the efficiency of face-milled hypoid gears. A full numerical analysis of the mixed EHL in hypoid gears is applied. The equation system and the numerical procedure are unified for a full coverage of all the lubrication regions, including the full film, mixed, and boundary lubrication. In the hydrodynamically lubricated areas, the calculation method employed is base

Abstract:

In this study, an optimization methodology is proposed to systematically define head-cutter geometry and machine tool settings to introduce optimal tooth modifications in face-hobbed hypoid gears. The goal of the optimization is to simultaneously minimize tooth contact pressures and angular displacement error of the driven gear, while concurrently confining the loaded contact pattern within the tooth boundaries. The proposed optimization procedure relies heavily on a loaded tooth contact analysis for the prediction of tooth contact pressure distribution and transmission errors. The objective f

Abstract:

Data-driven process control considering both geometric and loaded contact performance evaluations has been an increasingly important stage in field of spiral bevel and hypoid gears. A new data-driven manufacturing process control strategy is proposed for a high performance spiral bevel and hypoid gears. Here, to distinguish with the conventional simulated loaded tooth contact analysis (SLTCA) using economical finite element software package, the numerical loaded tooth contact analysis (NLTCA) is of more flexibility and practicality. In light of the advantages of the improved design for six sig

Abstract:

The design of spiral bevel and hypoid gears that have a shaft extended from both sides of the cone apex (straddle design) is considered. A main difficulty of such a design is determining the length and diameter of the shaft that might be undercut by the head cutter during gear tooth generation. A method that determines the free space available for the gear shaft is proposed. The approach avoids collision between the shaft being designed and the head cutter during tooth generation. The approach is illustrated with a numerical example.

Abstract:

In this paper, the design and calculation of planetary transmission with bevel gears for road vehicles is presented. It must transfer power to the wheels with the possibility that wheels can rotate at different speeds. The basic calculation of transmission is performed for the drive machine, where an internal combustion engine is chosen, and for the driven machine, which is a car, all forces of resistance are calculated so that the transmission needs to be overcome to move the car. Based on the standard ISO 23509:2016 norm, the calculation of geometry is performed for the input gear pair and i
