Genetic Algorithm for Optimizing Noiseless, Non-Lubricated Helical Gear Pair
This research is motivated by optimal designing of bevel gear pair for transmitting more power between shafts in the machine tool without noise and without lubricating oil. In this research, the parameters such as power, efficiency, weight and centre distance have been optimized since the parameters are the central part of the gear problem. The sub problem of reducing the noise, running without...
متن کاملAnalysis of gear rattle by means of a wavelet-based signal processing procedure
In the paper a wavelet-based signals processing technique for the experimental detection of the gear rattle produced by the teeth impacts in lightly loaded gears is proposed. The Discrete Wavelet Transform is used to decompose the signal of the angular relative motion of an helical gear pair, and the wavelet decomposition details are adopted to analyze the dynamic behavior under rattle conditio...
متن کاملبررسی پدیده gear rattle در گیربکس دستی اتومبیل
امروزه در تمام دنیا خودروسازان جهت کاستن عیوب خودرو تلاش می کنند. دسترسی به کیفیتی مطلوب جهت آسایش سرنشینان و جذب مشتری بسیار مهم است. در این زمینه یکی از دغدغه های اصلی از بین بردن انواع نویز در خودرو می باشد. صداهای زیادی در سیستم انتقال قدرت اتومبیل پدیدار می گردد. در بسیاری از سیستم-های انتقال قدرت دستی پدیده gear rattle بوجود می آید. برخورد دندانه چرخ دنده ها با یکدیگر باعث بوجود آمدن ارتع...
Ant Colony Optimization Algorithm for Helical Gear Designing in Non-lubricated Condition
Due to the standardization of helical gear design parameters and the constraints involved in the design and manufacturing, the size of the helical gear pairs are higher than the required. To improve the gear efficiency and performance, optimizing the helical gear parameters became essential. While significant research efforts have developed for less constrained systems, design for over-constrai...
متن کاملMass Flux Distribution Measurements and Visualizations of a Fluid Sheet Generated by a Partially Immersed Dip-Lubricated Gear
A simplified model of gearbox lubrication flow is investigated. A metric gear with module size 4 mm, tooth number 38, tip radius 80.25 mm and width 40 mm, is partially immersed and rotated between 0–12 1/s frequencies in room temperature distilled water. Flash and laser sheet visualizations of the global flow field and the boundary layer are presented. Resolved mass flow distributions in the fl...
