Elastohydrodynamics of a Worm Gear Contact
The paper is concerned with prediction of elastic contact and elastohydrodynamic film thickness in worm gears. Using the undeformed geometry of the gap between gear teeth in contact a three-dimensional elastic contact simulation technique has been developed for calculation of the true area of elastic contact under load relative to the wheel and worm surfaces. A parallel investigation of elastoh...
متن کاملTransmission Errors in Precision Worm Gear Drives
Transmission error is a measure of the positioning accuracy of a gear system. This has been widely documented in gearing for many years as the source of problems in noise and vibration. It is a result of errors in the contact conditions which affect the driven gear with respect to the rotation of the driver gear. This research aims to present a better understanding of the basic kinematics of wo...
متن کاملApplication of Genetic Algorithm to Optimize Worm Gear Design for Minimum Centre Distance
A gear transmission problem is one of the most complex optimization problems because of relationship between different variables. A gear design require the designer to compromise many design variables; i.e. continuous, discrete & integer variables in order to determine best performance of gear set. Numbers of conventional methods are available for solving different types of optimization problem...
متن کاملMathematical Model of a CNC Rotary Table Driven by a Worm Gear
This paper proposes a mathematical model of a CNC rotary table driven by a worm gear. The CNC rotary tables are generally utilized as rotary axes of 5-axis machining centres. In this study, a mathematical model which can simulate dynamic behaviours of rotary table is proposed. The model consists of inertia of motor, spur and worm gears, and table. Axial displacement of the worm is also consider...
متن کاملOptimal Design Based on Rough Set and Implementation of Worm Gear in Valve Actuator
Rough set optimization method was applied to design the worm gear in valve actuator. The superfluous constraints are reduced based on the methodology of rough set at the model of optimization that was established. The importance of each constraint condition and the coordination of the objective function can be got. Through example it can be seen that the optimal scheme made worm gear accord wit...
