Selection of Gear Ratio for Smooth Gear Shifting

SAE Technical Paper Series, 2012
<div class="section abstract"><div class="htmlview paragraph">Manual transmissions are characterized by gear ratios that are selectable by locking selected gear pairs to the output shaft inside the transmission. Top gear is selected to get a maximum speed and is limited by the engine power, speed and the fuel economy.

Investigation of the paired-gear method in selectivity studies [PDF]

Fisheries Research, 2009
We estimated selectivity parameters using simultaneously the paired-gear and covered codend method for two fish species and four different selection systems, for a total of eight study cases. The deviation (Δ) in L50 and SR between these sampling methods

Simulation-based investigation of the paired-gear method in cod-end selectivity studies [PDF]

Fisheries Research, 2007
In this paper, the paired-gear and covered cod-end methods for estimating the selectivity of trawl cod-ends are compared. A modified version of the cod-end selectivity simulator PRESEMO is used to simulate the data that would be collected from a paired ...

SELECTION OF GEAR TOOTH MATERIAL BASED ON THE WEAR RESISTANCE

Journal of Science and Innovative Development, 2022
This article reviews a method for selecting a gear material based on the wear resistance properties of teeth. The approach takes such properties as hardness, number of loading cycles leading the destruction a deformed layer of friction surface material and correlation of hardness of gear material and strength of abrasive particles in wedgeshaped gap of

Influence of gear selectivity on FIE and yield

2014
No abstracts are to be cited without prior reference to the author. Size‐selective fishing alters the demographic composition of fish stocks, influences population dynamics and may result in evolutionary changes of life‐history traits. While mortality through fishing inevitably affects the stock, size selectivity can intensify or mitigate detrimental ...

The selection of variable gear for minimum energy

IEEE Transactions on Automatic Control, 1972
The system under consideration is that of a motor, coupled by a gear train to an inertial load, where the requirement is to rotate the load by a given angle and come to a halt. The question considered is whether the use of a variable gear, instead of one with constant ratio, will reduce the required energy, and if so, what are the optimal gear ratio ...

Selection of number of gear teeth for machine tool gear boxes

International Journal of Machine Tool Design and Research, 1974
Abstract The output speeds on machine tool spindles follow a geometric progression. International and various national standards specify the permissible errors in speeds due to mechanical and electrical variations. The errors arising out of mechanical variations are mainly due to the limitations on the choice of the number of gear teeth.
