Hello,
I'm specifying torque values for screws on a steel assembly (using standard torque tables). For some, i reduced the torque values where the screws are large relative to the materials being clamped & the holes threaded, e.g., when a 3/4" bolt is clamping a 1/4" thick steel plate to a 1/4"...
Hello,
I'm attempting to design an all-plastic, low speed 2' dia rolling cylinder. This is a 1-of-a-kind & I want to drive it by way of roller pins instead of involute machining. I'm curious if anyone can shed light on how i should handle the tooth profile geometry. An example is Nexen group's...
Hi,
I'm looking to design a piping system for about 4 coolant lines (3" dia each) carrying ethylene glycol to a shelter resting on an Azimuth turntable. Because the turntable will need less than 3/4 of a rotation, I want to stack 4 swivel fittings over the center of rotation. The expected...
I have a slipping HTD timing belt. We use custom length endless timing belts that we can't get in neoprene. We've found the polyurethane more subject to slippage/climbing teeth. I sprayed some aerosol glue & it seems to help. Is this common practice or is there anything better?
Thanks, VBK
I'm comparing the merits of using steel versus aluminum for an L-bracket. It is to be mounted on a motorized turntable oriented perpendicular to the ground. It'll be about 5' x 6' & have about 300 lbs at the end. Although I can use cntr-weight, I prefer to minimize it. Deflection is my main...
