Abstract
1338589 Load cells for aircraft B L H ELECTRONICS Inc 29 Dec 1970 [14 Jan 1970] 61640/70 Heading G1N A load cell for use in determining the load on a centrally supported hollow axle by measuring the shear forces on each half of the axle comprises strain gauges 39-42 Fig. 9 mounted on a cylindrical member 34 fixed inside the axle 21 by radially expandable collets 36, 37, one load cell assembly being mounted on each side of the central support. The strain gauges are bonded in diametrically vertical locations on the inner surfaces of flexible portions 35c, 35d of member 34 and rigid end portions 35a, 35b are supported by the collets which are compressed by screws 52 to engage the inner surface of the axle 21. The strain gauges 39-42 are connected into a bridge circuit which measures the shear stress and automatically cancels out bending stresses. The load cell may be formed asymmetrically to compensate for asymmetry of the axle.
