    Belt Load Pulley
AI Thread Summary
To determine the shaft load on pulleys in a belt drive system with three or four pulleys, the discussion emphasizes the need for clarity in the setup and calculations. The basic approach involves using mechanics to calculate forces in the belt, applying equations related to tension and friction. Participants suggest that understanding the relationships between the forces acting on the pulleys is crucial for accurate calculations. Additionally, references to textbooks and belt handbooks are sought for further guidance. The conversation highlights the complexity of the problem and the importance of clear diagrams for effective communication.

Dear all,

My objective is to find shaft load in which belt pulley is mounted and load being transmitted via belt.
In the case of two pulley belt drives ,the load to the pulley mounting shafts calculation can found by getting guidance in almost all textbooks(T1 &T2 relations). Where in my case 3 as well as 4 pulleys and one single belt transmit the power. Now i need to find each pulley shaft load what is the procedure to be followed?Any belt hand books dealing this?

Ref.books,ref.materials,sites are welcome

Thanks

Your question isn't very clear. Can you put up a drawing?

Do you mean a shaft with one pulley getting the power & transferring it to other shafts through other pulleys on the same shaft?
 
For ur clarification fig is attached.

Thank u
Prakash

Sorry, the question still isn't very clear to me.

I assume you are trying to calculate the forces in the belt. You can calculate it using simple mechanics

^{F}1-^{F}2 = \frac{T}{r}

\frac{^{F}1}{{F}2}=_{e}\mu\theta.

Duh, sorry can't get the latex going:mad:

Anyways, there are 3 pulleys, so three unknown forces & three equations to solve. Good luck.:smile:
 
How did you find PF?: Via Google search Hi, I have a vessel I 3D printed to investigate single bubble rise. The vessel has a 4 mm gap separated by acrylic panels. This is essentially my viewing chamber where I can record the bubble motion. The vessel is open to atmosphere. The bubble generation mechanism is composed of a syringe pump and glass capillary tube (Internal Diameter of 0.45 mm). I connect a 1/4” air line hose from the syringe to the capillary The bubble is formed at the tip...
Thread 'Physics of Stretch: What pressure does a band apply on a cylinder?'
Scenario 1 (figure 1) A continuous loop of elastic material is stretched around two metal bars. The top bar is attached to a load cell that reads force. The lower bar can be moved downwards to stretch the elastic material. The lower bar is moved downwards until the two bars are 1190mm apart, stretching the elastic material. The bars are 5mm thick, so the total internal loop length is 1200mm (1190mm + 5mm + 5mm). At this level of stretch, the load cell reads 45N tensile force. Key numbers...
I'd like to create a thread with links to 3-D Printer resources, including printers and software package suggestions. My motivations are selfish, as I have a 3-D printed project that I'm working on, and I'd like to buy a simple printer and use low cost software to make the first prototype. There are some previous threads about 3-D printing like this: https://www.physicsforums.com/threads/are-3d-printers-easy-to-use-yet.917489/ but none that address the overall topic (unless I've missed...
