PCT No. PCT/SE96/00473 Sec. 371 Date Oct. 8, 1997 Sec. 102(e) Date Oct. 8, 1997 PCT Filed Apr. 11, 1996 PCT Pub. No. WO96/32630 PCT Pub. Date Oct. 17, 1996A method for measurement of axial forces acting on a shaft, being supplied with gas under overpressure such that gas pressure is built up between two opposing faces of said portion projecting radially from the shaft and at least one gas-permeable body provided external to said faces. A gas differential between the gas pressure on said opposing faces is established, and the axial force acting on said shaft is determined as a product of a constant and the pressure differential between the gas pressures on the two faces. Means are provided for supply of gas under overpressure to said body and pressure measuring means are provided for measurement of the pressure differential between the pressures on the two faces of the radially projecting portion. The protruding portion may also constitute a measuring plate which, provided in various manners, is subjected to forces. |
