Gear Data: Spline Date DIN 5480 - HELP

Gear Data: Spline Date DIN 5480 - HELP

Gear Data: Spline Date DIN 5480 - HELP

(OP)
How can I get my inspection requirements for DIN 5480 N74x2x30x36xG7? Tells me the dM=3.5 but I cannot find the module for this in the specs.

Any help?? How Can I find the inspection requirements / nominal dimensions (root diameter, etc.)

RE: Gear Data: Spline Date DIN 5480 - HELP

I think you will need to get DIN 5480 to find out. The inspection requirements and tolerances may be in another standard as well, since DIN and ISO like to segment their content as much as they can.

I did find a copy from the Internet which is probably not the latest, but module is defined by the nominal spline diameter and number of teeth. So I'm reading your callout as Nave dB 74mm, 2mm module, 30 teeth, G7 flank fit. I don't know what the 36 is.

Unfortunately 74 is not a preferred diameter so I think you'll have to dig into the standard(s) and run the numbers for 74.
