The planet carrier transmits the driving torque to the planet gears that move around inside the inner circumference of the ring wheel. The number of the planet gears is a design variable which is often chosen as three. The speed-up ratio for this configuration can be expressed by the ...
3207 Analysis of Driver's Steering Behavior by Changing the Relation between Steering Gear Ratio and Steering Torque Recently, intelligent steering systems using the Electric Power Steering (EPS) system are developed. In order to improve driver's maneuver and vehicle resp... S Nomura,H Yoshida,M...
And then according to this model analyses the rotating relation and torque relation of dual planetary gear transmission system deduces the calculation formula of transmission rate efficiency. The sensitivity of each gear ratio to transmission efficiency is defined with the method of sensitivity analysis....
(4), is given by the ratio of the applied torque (T) and the transmission error. Notice that the concept of stiffness is related to the elastic deflections and, therefore, the no-load transmission error (associated to the manufacturing errors) should, by definition, be removed from the ...
A toothed wheel gear change box with several speeds and a grouped design has in the lower speed range a bigger ratio spacing than in the intermediate and upper speed ranges, so that a favourable gradation for vehicle drives can be obtain... W Kuhn,H Domian,KH Bordowsky 被引量: 0发表: ...
The finite element model in experiment 8 is divided into 149265 units and 160243 nodes. The material of the ring gear is 42CrMoA, the elastic modulus E = 206 GPa, and Poisson’s ratio ν = 0.3. The material of the gearbox is QT450, the elastic modulus E = 147 GPa, and Poisson’s ...
Furthermore, the first gear is the biggest in a gearbox and provides maximum torque output while producing minimum speed. Hence, the drivers use it when climbing slopes. All the gears between 1st and last gear vary in size, in a decreasing ratio. Thus, it provides a varying combination of...
This combination reduces the speed of the driven member and also multiplies its torque; increasing it proportionally as the speed decreases. The speed ratio of shafts depends upon the relation of the number of threads on the worm to the number of teeth in the worm wheel or gea...
The ratio of rotation between the spindle of the workpiece blank and cradle is referred to as ratio of roll. Generative type machine tools in which the cutter axis is able to tilt are known as tilting spindle machines. They maintain a constant ratio of roll during the generative process. ...
