I'm building a machine that has a 25-pin shielded conductor cable between the control box and the equipment itself. At the moment, I am using 17 of the conductors leaving others open for possible future expansion (though we have no immediate plans for them). My question is whether or not I...
I have a CNC turned AISI 1144 shaft that is about 140mm long and 10mm OD. There is another (aluminum) piece that fits over the shaft that must slide smoothly along the axis and I am using composite bearings pressed into the outer sleeve for the interface which works well. The issue I'm having...
I'm working on an application where I need to intercept an existing PWM signal (~120Hz, 0-12.0V) - which is limited to 20A max current - and output an identical signal with a capacity of up to 60A. The signal controls a single brushless DC motor but my application will add another (identical)...
Fluid dynamics is outside my expertise and well outside my normal area of work, so looking for some "rule of thumb" type guidance. The reality of the application is that other restrictions downstream make this component nearly moot, but I want it to be right regardless and hopefully I'll learn...
We have a device we're working on that contains a pair of bevel gears that are about 8:1 ratio (pinion is 0.6"OD, ring is 3.5"OD) and 22DP. Machining these from 303 stainless is expensive, even at reasonable volumes (1,000-10,000/year). Our gear set is very low RPM (<200rpm on the pinion) and...
I'm adhesives dumb, so please bear with me!
I'm working on a next-gen prototype of an automotive/powersports device. It will see lots of vibration, and some thermal variation (maybe up to 300F tops). Functionally, the aluminum part (4" disc 0.050" thick) has become obsolete, but is needed for...
Hi guys, I'm not a hydraulics guy by any stretch, so please forgive me if this is a fundamentally dumb question. I'm working on a concept that requires (ideally) the use of a spring-loaded (floating) piston type hydraulic accumulator with a capacity in the 50cc-75cc range and pressure...
Hi guys - I'm brand new to the forum as a member, but have been lurking for months as I transition from the world of corporate Information Technology to working for myself at my own Mechanical Design company. So, first off, thanks for all the great information here!
My business is basically a...
