Torque on the pinion. The torque on the pinion is simply the tangential force (force on the rack) multiplied by the pinion radius. T p = torque on pinion (Nm, ft-lb) r p = pinion radius (m, ft) Remember to divide the pinion diameter by 2 to get the radius, and by 1000 to convert from mm to m (or by 12 to convert from inches to feet).
Cb= circumference of belt. Db= Diameter of belt. Dpo= Outer Diameter of pulley. Dpi= Inner Diameter of pulley. Tb= Thickness of belt, measured from tooth valley to the flat side of the belt. Ht= Height of the tooth on the belt. Cb= N*P Db= Cb/&pi Dpo= Db- 2*Tb Dpi= Dpo- 2*Ht Be consistent with your units when entering data into the calculator.

The above equations are mainly used to calculate the torque required by the motor due to "frictional forces". Generally speaking, conveyors are designed to not require fast acceleration since they usually just run continuously so they are given a long startup time.
Belt Load. At one time when the load is known per square foot: P= G 1 x C(in feet)x W (in feet) At one time when load is known by pounds per hour: P=G 2 /(S x 60) x C(in feet) Horsepower.

In order to find the maximum tension is necessary to calculate the effective tension, that is, the force required to move the conveyor and the load at a constant speed. The calculation of the total tension is based on a constant speed of the belt including the necessary basic conditions to overcome the frictional resistance and tension forces.
In rotating vertical shaft calculations, torque is important because it determines the amount of power needed to rotate the shaft and can also affect the stability and efficiency of the shaft. 2.

Torque and Power Transmission in Belt-Driven Systems. In belt-driven systems there is usually an input pulley and one or more output pulleys. To determine the maximum torque or power that can be transmitted by the belt, we will need to consider each of the pulleys independently, understanding that slipping occurring at either the …
Calculating Steps/mm Using Belts and Pulleys. In many of our machines we have used belts and pulleys to actuate them. These belts and pulleys come in many shapes and sizes, but one standard we have grown accustomed to is the GT2 standard. GT2 belts and pulleys come in (at least) three different sizes: 2 mm, 3 mm and 5 mm pitch.
But in this class, we will typically use equation ref{tau-Fperp} to calculate the torque, and the RHR to determine its direction. Figure 7.5.5 shows the position vector (vec r) drawn from the pivot to the location of the force, and then the perpendicular component of the force is depicted as (F_{perp}).

For a belt drive system, the motor torque required during constant velocity is simply the total axial force (F a) on the belt …
Torque describes the rotational equivalent of a linear force. It is the measure of the force that can cause an object to rotate about an axis. Torque is measured in lb-in (pounds-inch) or Nm (newton meter). When it comes to motor drive torque for beltand pulley transmission systems, designers must understand that torque con…
The maximum torque of the selected drive motor is used to calculate the size of the motor pulley. The rule is to use the greatest motor torque available during start-up, however, braking loads should also be considered. ... Vertical timing belt drives have special requirements because of the build-up of potential energy during lifting ...
Equation (17.4.3) contains the unknown frictional torque, and this torque is determined by considering the slowing of the rotor/washer after the string has detached. Figure 17.27 Torque diagram on rotor when string has detached. The torque on the system is just this frictional torque (Figure 17.27), and so [-tau_{f}=I_{R} alpha_{2} nonumber ]
