I really meant one bolt diameter length.
or plus 30mm in your case. This assumes the
effective length penetrates into the head 15mm
and into the concrete 15mm.
I recommend getting your hands on or have your company buy you - Mechanical Engineering Design by Shingley.
Shingley should be Shigley. I now that is what you meant.
Is it still common to add one bolt length to the effective length to account for 1/2 penetrations in nut and head?
I have seen this is some standards. If so it would be
as civilperson suggests except one bolt length would be
added to the length.
I think the standard 1 module would have
a .50 addendum and .65 dedendum with the
dedendum dependent on whether is is root
bottom fit or side to side fit.
You are going to need more input as to dimensionions
over balls or pins. Is the spline an ivolute spline or
straight sided? Module splines are often designed non
standard is Europe and maybe also in Russia.
I assume it is a 30 degree pressure angle spline.
I think you are suggesting that it is...
I have a feeling that this 10.2 dp was actually 10.16dp making it a 2.5 Module Gear in its first or original design. Probably a round up error was made at some point in the translation.
Matt 51,
If both members of the long and short addendum are modified by the same amount they still operate on the
standard center distance and pressure angles.
You are right if only one is modified or they are not
modified by the same amount the operating pressure angles do change.
You can get the same result by using the 10.2 dp
and 25 degree pressure angle for the pinion and
use 50 percent long addendum design.
If the base diameters have the same ratio as the
number of teeth, they will operate, ie the base
pitch is the same. You do not need to define the
pinion as the...
I am surprised that there would not be a relationship to the general ISO tolerances based on the tooth thickness
or space width. Our buddies across the pond do seem to be very standard oriented.
I am curious why you did not select a standard 48Dp instead of 50Dp. 48 or 64 are more common for fine pitch gears. Maybe that is the reason why your inspector is asking the question. Pins for the 48Dp system might be more readily available.
From Wikipedia:
Hertzian contact stress refers to the localized stresses that develop as two curved surfaces come in contact and deform slightly under the imposed loads. This amount of deformation is dependent on the elasticity of the the material in contact, i.e., its modulus of elasticity. It...
Are you implying that you can buy these in grade 5 and
8 or 9 and use the standard clamping force. I do not think he is talking about socket head bolts in a counterbored hole. I thought c'sunk heads were only good
for small clamping forces.
