Simulation of Hypoid Gear Lapping

Journal of Mechanical Design, 2008
In the lapping process of hypoid gears, a gear set is run at varying operating positions and under a light load in order to lap the complete tooth surface. Because of the rolling and sliding motion inherent to hypoid gears, the lapping compound acts as an abrasive and refines the tooth surface to achieve smoothness in rolling action and produce high ...

The lapping mechanism of hypoid gears

Journal of Materials Processing Technology, 2009
Based on the analysis of the transmission errors and the effect contact ratio under lapping, the mean boundaries of the lapping contact of tooth surface are determined and the lapping paths are schemed. The relative lapping rate of the tooth surface is estimated by means of the synthesis of the sliding coefficient, the lapping probability and the ...

Elastohydrodynamic Lubrication of Hypoid Gears

Journal of Mechanical Design, 1981
The full thermal elastohydrodynamic analysis of the lubrication of hypoid gears is presented. A numerical solution of the coupled Reynolds, elasticity and energy equations for the pressure, temperature and film thickness is obtained. The temperature variations across the oil film and in the pinion and gear teeth are included. The real tooth geometry of

Hobbing of Bevel and Hypoid Gears

Volume 5: 25th International Conference on Design Theory and Methodology; ASME 2013 Power Transmission and Gearing Conference, 2013
The paper presents a hyperboloidal hob cutter similar to a cylindrical hob cutter used to fabricate spur and helical gear elements today. This hyperboloidal cutter can be used to manufacture bevel and hypoid gear elements using an existing CNC hobbing machine. These bevel and hypoid gear elements can be either spur or spiral.

Nodular Iron Hypoid Gears

SAE Technical Paper Series, 1982
<div class="htmlview paragraph">Successful conversion of nodular iron hypoid gears from steel to nodular iron required initial vehicle and laboratory fatigue tests to supplement a material development program. This was followed by manufacturing process refinement and finally an extensive series of vehicle durability tests. Nodular iron gears have

Experimental studies and simulation of hypoid gear lapping

Forschung im Ingenieurwesen, 2017
Gear lapping is a highly productive method of hard finishing hypoid gears for appliances with high demands regarding transmission noise. However, there is a major disadvantage compared to competing processes. The flank topology after lapping is not completely predictable, making the definition of process variables a matter of personal experience and ...

Some studies on hypoid face gears

Mechanism and Machine Theory, 1973
Abstract Some of the geometric characteristics of a hypoid face gear in mesh with an involute spur pinion are analysed. These geometric characteristics include (a) the maximum diameter of the hypoid gear to avoid pointing of the teeth, (b) the minimum diameter for avoiding undercutting, (c) the contact ratio, (d) the field of contact and (e) the ...

Gear-Cutting Method of Parallel Depth Hypoid Gears

Volume 4: 9th International Power Transmission and Gearing Conference, Parts A and B, 2003
The purpose of this study is to develop a gear-cutting method of hypoid gears to achieve a good tooth bearing and good performance for practical use. In this report, the authors propose a new cutting method of parallel depth hypoid gears, which mesh with each other at one point keeping a constant angular velocity ratio, and describe the theory for the ...

Load Distribution in Hypoid Gears

Journal of Mechanical Design, 1998
A new approach for the computerized simulation of load distribution in mismatched hypoid gears with point contact is presented. The load distribution calculation is based on the bending and shearing deflections of gear teeth, on the local contact deformations of the mating surfaces, on gear body bending and torsion, on the deflections of the supporting
