    Force Resistance
AI Thread Summary
Calculating the resistance force in a gearbox involves assessing the friction from bearings and gear teeth. Bearing manufacturers, like SKF, provide valuable data and formulas for determining bearing friction. Gear teeth friction is influenced by lubrication type and can increase with load and speed. Understanding these factors is crucial for determining the force needed to turn the input shaft of a gearbox. Accurate calculations ensure efficient gearbox performance and longevity.

Resistance force??

How is resistance force from the input thru to the output of a gearbox calculated? I want to know how to figure out how much force is required to turn a shaft at the input side of my gearbox. Any help would be greatly appreciated.

The bearing makers should be able to tell you the friction of the bearings. SKF is pretty good with formulas and data for this sort of thing.

The gear teeth friction will depend on what kind of lubrication you have and will increase with load, and possibly with speed also.
 


Thanks Unrest. I will use the info today!
 

Thread 'Bubble formation in 4 mm gap vessel'

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...

Thread 'Find 3D Printer & Software Resources for Prototype Creation'

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...
