0. I would like to calculate the required motor torque to turn a rover wheel whilst the rover is stationary. I have modelled the friction force as a distributed force acting equally along the width of the wheels, working against the turning direction (shown as clockwise). From here I took an equivalent force of the weight multiplied by the ...

Once the wheel just is about to roll over, normal force should be zero: $$ N = 0 $$ And thus: $$ mg = -sin(38.7)k $$ Based on these caluclations I assumed I'd find F by $$ F = -cos(38.7)k $$ This didn't give me the correct answer. So I turn to you guys (mind you, I've tried different methods as well).

The torque is obtained by integrating the frictional force multiplied by roll radius over the arc of contact (lagging and leading zones). The negative sign before the second term is due to the fact that in leading zone the metal moves faster than the rolls hence it helps to rotate the rolls. The above integration leads to rather complex ...

Then you just divide the torque value by (2.3*0.2) to get the torque value at the motor. However, losses such as the transmission efficiency and so on have to be catered for as well as a safety factor. So it's better to divide your initial value of torque by the safety factors and losses to get the actual required value of torque.

To illustrate the application of the pulley torque calculator, consider a scenario where an engineer needs to calculate the torque required to lift a heavy object using a pulley system. If the force applied is 500N, the radius of the pulley is 0.5m, and the system's efficiency is estimated at 85% (or 0.85), the calculation would be as follows:

The Formula. The formula for calculating wheel torque is: Wheel Torque = Engine Torque / Drive Layout. The engine torque is the amount of rotational force generated by the engine, typically measured in pound-feet (lb-ft) or Newton-meters (Nm). The drive layout refers to the type of drivetrain, which can be front-wheel drive (FWD), …

I'm building a robot that flips itself over using a gyroscope . The gyroscope spins horizontaly at first, then a servo changes the gyro's rotating axis, making the robot flip in the opposite direction.

Drive torque is primarily influenced by the axial load on the screw and the screw's lead. F a = total axial force (N) P = lead (mm) η = efficiency of ball screw. The axial load is not only the process force (drilling, punching, etc.), but also includes the force required to move the load. Since most ball screw assemblies use profiled guide ...

The torque needed to rotate a cylinder can be calculated by multiplying the force applied to the cylinder by the distance from the axis of rotation to the point where the force is applied. This is known as the lever arm or moment arm. The resulting value is the torque in Newton-meters or foot-pounds. 5.

For an 'order of magnitude' calculation (usually written on a napkin), just take the width of the wheel, divide it in half. That's your 'torque arm'. Then take the force needed to slide the wheel (say, in Pounds) over the surface. Multiply the force by the torque arm, that's a close estimate. Table of Contents show.

Following our gear ratio equation, we can say that this gear train has a gear ratio of 10:40, 10/40, or simply 1/4 (or 0.25). This gear ratio means that the output gear would only rotate 1/4 of a full rotation after the input gear has completed a full turn.Continuing in this fashion and keeping a consistent input speed, we see that the …
