# belt drives

hey guys tell me how to determine the following:

consider two v-pulleys connected by a v belt. the speed at which the driving pulley rotates is known . how do we determine the torque on the driver pulley as well as the speed of the driven pulley and the torque transmitted to the driven pulley by the driver.

we know : the diameters of both the pulleys

the angle of slip of the belt

Yeah, even I faced one!!! 😔 The_Big_K, please look into this...bioramaniserver trouble. Multiple posts.

Problem fixed. We're performing server operations that result into lag. Sorry for the inconvenience.

Is it just me? The quoted post says it is #2, while there are more than 3 posts above!!!The_Big_KProblem fixed. We're performing server operations that result into lag. Sorry for the inconvenience.

Praveen-Kumar : You are spamming this thread. Stick to the topic, please.

To determine the torque on the driver pulley you must first find the tensions T1 and T2 on the belt.

Torque = (T1-T2)*(Radius of the driver pulley)

To determine Speed of the driven:

Use the ratio: Speed of Driver * Radius of Driver = Speed of Driven * Radius of Driven

i.e. v1r1 = v2r2

Torque = (T1-T2)*(Radius of the driver pulley)

To determine Speed of the driven:

Use the ratio: Speed of Driver * Radius of Driver = Speed of Driven * Radius of Driven

i.e. v1r1 = v2r2

thanx a lot dude, now can u tell me how to determine the belt tensionsCE DesignerTo determine the torque on the driver pulley you must first find the tensions T1 and T2 on the belt.

Torque = (T1-T2)*(Radius of the driver pulley)

To determine Speed of the driven:

Use the ratio: Speed of Driver * Radius of Driver = Speed of Driven * Radius of Driven

i.e. v1r1 = v2r2

e^(u)(theta) = (T1-Tc)/(T2-Tc)

where T1 is the maximum tension which the belt is specified for

u = coefficient of friction

Tc = mv^2

m = mass of the belt

v =RPM*(2pie/60)*radius of driver

You can now find T2 knowing T1 and Tc.

be sure to use standard units and theta is in radians

thanx again. but the problem is i do not know T1 either . now what to doCE DesignerYou can now find T2 knowing T1 and Tc.

I would suggest you search the manufacturer's specifications. Call your supplier or visit their website.

I am not sure but check on the belt itself to see if there is any indication there.
