AI Thread Summary
The discussion focuses on finding spur gears with a ratio of .31, a maximum width of .5 inches, and an outside diameter of 2.4 inches. McMaster-Carr's gears are deemed too wide, prompting suggestions to check Boston Gear and Stock Drive Products for suitable options. Steel construction is required for durability, as the gears will need to withstand a load of 300 lbs for a specialized vice design. Stock Drive Products is highlighted for its wide selection of gears. The conversation emphasizes the importance of finding the right specifications for effective gear performance.

Mcmaster carr's gears are a bit too wide for my design.

I need a pair of gears to have a ratio of .31, that is around .7" to 2.38"

The widths for the gears can not be any larger than .5" and ideally even less, at Mcmaster Carr they are about 1"

Have to be made of steel.

Cannot be any larger than 2.4" outside diameter.

Boston Gear used to offer a variety of spur gears. Not sure now, but might be worth checking.
 
Give Stock Drive Products a try.

Wow, thank you very much man, they have a very nice wide selection that I have never seen before. I'm sure I will find it here.

Now to just calculate the failure because I need my gears to survive a simple load of 300lbs. I am building a type of vice to break small samples of metal, quite opposite of what a vice does.

Thread 'Cantilever help'

I'm trying to decide what size and type of galvanized steel I need for 2 cantilever extensions. The cantilever is 5 ft. The space between the two cantilever arms is a 17 ft Gap the center 7 ft of the 17 ft Gap we'll need to Bear approximately 17,000 lb spread evenly from the front of the cantilever to the back of the cantilever over 5 ft. I will put support beams across these cantilever arms to support the load evenly

Thread 'What's the most likely cause for this carbon seal crack?'

Thread 'What's the most likely cause for this carbon seal crack?'

We have a molded carbon graphite seal that is used in an inline axial piston, variable displacement hydraulic pump. One of our customers reported that, when using the “A” parts in the past, they only needed to replace them due to normal wear. However, after switching to our parts, the replacement cycle seems to be much shorter due to “broken” or “cracked” failures. This issue was identified after hydraulic fluid leakage was observed. According to their records, the same problem has occurred...
