This paper presents a new concept of a mobile robot speed control by using two degree of freedom gear transmission. The developed intelligent speed controller utilizes a gear box which comprises of epicyclic gear train with two inputs, one coupled with the engine shaft and another with the shaft of a variable speed dc motor. The net output speed is a combination of the two input speeds and is g...

called a Parallel Force/Velocity Actuator (PFVA), that combines two fundamentally distinct actuators (one using low gear reduction or even direct drive, which we will call a Force Actuator (FA) and the other with a high reduction gear train that we will refer to as a Velocity Actuator (VA)). The objective of this work is to evaluate the effect of the relative scale factor, RSF, (ratio of gear r...

in this research was designed a differential lock control system. the system was test and evaluated after fabrication and its accuracy and precision was determined. a field experiment with three replications was conducted to investigate the effect of gear ratio, the method of tractor movement during plowing and differential position on drive wheel slippage and fuel consumption of mf399 tractor ...

Abstract The demands of high carrying capacity and low vibration gear transmission systems in aviation, aerospace, other areas are addressed by contact ratio gears with asymmetric teeth, which have a wide range potential applications. Weber energy technique is utilized to determine the stiffness spur effect law parameters researched, due paucity study on these gears. influence drive side addend...
