Is it possible to buy paint which absorbs IR light?
I would like to measure the temperature of a small target (1mmx1mm) using an optical pyrometer. The problem is that I will probably end up measurinmg the reflected heat from the the surfaces around the target. It has been suggested that I could...
Does anyone know how to caclulate temperature gradient along a hollow cone. Heat flow is from small end of cone towards larger end. I am only interested in heat flow inside the walls of the cone.
Hi Gear Experts!
I need to specify plastic gears for tooling in China. They work to AGMA standards whereas we work to ISO. Is the ISO 1328 quality class the same as AGMA?
And a second question, do I need to specify total and tooth-to-tooth tangential composite deviation in the gear table or is...
Does anyone know which standards (Euro Norms or equiv)do I need to use when specifying: A) Electrolytic Zinc Plating of formed mild Steel sheet metal parts and B) Passivation using Cr3 and conforming to RoHS. This will be used in an office machine. Thanks Matt
Hi,
Does anyone know of any technical information about heat / utrasonic staking for joining a plastic injection mouldedpart to a sheet metal part. I want to use one of these processes to avoid using screws but I have found very little technical information. I would like to know what are the...
Hi,
I want to design a spring that is manufacturable.
I need to know acceptable values for number of active coils and initial tension for extension springs.
I am using 0.63mm dia spring steel.
I have got 8.5 active coils and an initial tension of 1.337N which is 8.5% of the max spring force...
Hi,
Does anyone know what to call welding which requires no filler. In german it is called "verschwemmt" but I have been unable to find a translation into english. We put this text on drawings of sheet metal parts where a mortice joint between two st. steel parts is welded after...
I need to specify a very lightly loaded plain bearing for a bank note handling machine (id6mm od8mm l10mm). The radial loads are minimal and the axial load is nothing. The bearing oscillates through an angle of 1 degree at 10Hz. I was thinking of using a Glacier DU PTFE/Steel but I don't want to...
I am designing a small (Dia 26mm x 200mm) roller mechanism that currently uses springs in parallel with relatively expensive oil dampers. I would like find a cheaper solution using rubber parts in series with the spring to replace the oil dampers.
Can anyone recommend any useful sources of...
I am designing a small (Dia 26mm x 200mm) roller mechanism that currently has an expensive spring and oil damper suspension system. I would like find a cheaper solution, possibly using a rubber damper. Can anyone recommend any useful sources of design data for rubber damper design?
Thanks
I would like to know if there is any data available for the magnetic losses caused by shock loading a small SmCo magnet. I have a magnet which is used in conjuction with a Hall effect sensor to make a displacement measurement of a lever. The magnet is subject to approx 12g shock which is...
I need to specify a magnet to operate a linear hall effect device for small displacement measurements. The Hall effect sensor works within a range specified in gauss. The SmCo magnets are specified in Newtons. Does anyone know if it is possible to make a conversion and how?
