STEEL PROFILES AND USEFUL PRESSURE CALCULATIONS SPECIFIED ON THE PROFILES
These profiles are proper to fittings of lifting for heavy loads:
In the sector of the carts industrial elevators, in the equipments for the industrial movimentazione, and having a different ability of load between them, also in the systems of stoccaggio and selves.
When an application involves the use of combined bearings and rolled profiles in addition to the dimensioning of the bearing (see previous paragraphs) must also pay attention to the resistance of the profile that unlike the bearing does not require heat treatments that increase the structural strength. Roller profiles type HOESCH supplied from DISTITEC S.R.L. are in structural steel Fe 510C (ST 52-3 U). The resistance of this material is the following:
P0 = 750 N/mm2
For this calculation uses the formula derived from the HERTZ theory relative to the crushing and to the specific pressure that is generated between two solid bodies elastic contact linear subjected to a load. Given the complexity of the calculation suggest that you contact our technical department.
It depends on the applied load and the number of revolutions and is calculated in the following way:
L = (C/P)P Lh=(16666/n)x(C/P)p
