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.

The selection of variable gear for minimum energy
IEEE Transactions on Automatic Control, 1972The 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, 1974Abstract 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.

Virtual selection of the optimal gear-set in a race car
International Journal of Vehicle Systems Modelling and Testing, 2008The problem considered in this paper is the optimisation of the gear-set of a race car in a virtual (software) environment. This task has been split into three sub-tasks: first, the maximum achievable speed (as a function of the local curvature radius) in every position of the circuit has been computed; then, the lap-time has been computed with an ...
