I spent a lot of time researching how much land or bearing length
should be used in a core for various sizes of ejector pins.
Many researches on improving its load capacity were carried out using an analytical method by solving the classical Reynolds lubrication equation, assuming that the bearing length
should be at least 100 times of the film thickness.
The connecting rod (conrod) bearing length
was reduced in order to increase the Maximum Specific Load (MSL) on the connecting rod bearings to 105MPa.
The barrel extension has about one inch of bearing length
, not including the flange, and cutting the shim stock a little on the narrow side gives me leeway to keep it centered and not extending out from either the front or back.
The fractured pin stripes and the ankle bearing length
are sure to be big this year.
The same technique was used to study the effective bearing length
of timber member under partial bearing just like contact joints between columns and sills.
paper web width 6 660 mm Nominal diameter 1 067 mm Shell thickness of the roll body 198 mm Bearing length
8 400 mm Number of peripheral bores 40 Diameter of peripheral bores [phi]32 mm Layer thickness of white iron 9 mm Layer thickness of mottle iron 42 mm
Since both of the flow variables, [Q.sub.rj]/rcNL and [Q.sub.s]/[Q.sub.rj], are functions of the Sommerfeld number and the ratio of bearing length
to diameter (Shigley and Mischke 2001), the side leakage can be computed using the following:
where P: load, L: bearing length
of dowel, d: diameter of dowel.
Three of them were considered the most practical interest: the surface roughness Ra [[micro]m], processing at a bearing length
ratio cut to 50% [t.sub.p05] [%] and productivity [Q.sub.s] [%].
And he says they allow the machines to easily accommodate stack molds by simply extending the bearing length
* The GBGYB/GBGY with an outer fixed ring and pilot extension bearing lengths
from 40 to 100 mm and ID from 15 to 40 mm.
