Embodiment Construction

[0022] figure 1 A first embodiment of the load cell 10 of the present invention is illustrated. The load cell 10 preferably comprises a unitary body 12 of the invention which is formed from one piece of material. The body 12 includes a rigid central hub 14 concentric with a rigid ring 16, and a plurality of radial tubes 20 connect the central hub 14 and the ring 16 together. In the illustrated embodiment, the plurality of radial tubes 20 consists of four tubes 21 , 22 , 23 and 24 . Each of the tubes 21 - 24 extends from the central hub 14 to the ring 16 along a respective longitudinal axis 21A, 22A, 23A, 24A. Preferably, axis 21A is aligned with axis 23A and axis 22A is aligned with axis 24A. Additionally, axes 21A and 23A are perpendicular to axes 22A and 24A. Although four radial tubes 20 are shown here, it should be understood that any number of tubes 20 three or more may be used to connect the central hub 14 to the collar 16 . Preferably, a plurality of radial tubes 2...

Abstract

A load cell body (10, 10') for measuring components of force and moment in plural direction includes an integral assembly having a rigid central hub (14) and a rigid annular ring (16) concentric with the central hub (14). At least three radial tubes (21, 22, 23, 24) extend radially along corresponding longitudinal axes (21A, 22A, 23A, 24A) from the central hub (14) to the annular ring (16). Flexure members (31, 32, 33, 34) join the radial tubes (21, 22, 23, 24) to the the annular ring (16). Each flexure member (31, 32, 33, 34) is compliant for displacemnt of each corresponding radial (21, 22, 23, 24) tube along the corresponding longitudinal axis (21A, 22A, 23A, 24A). As a load cell (10, 10'), a strain sensor (44, 46, 48) mounted on each radial tube (21, 22, 23, 24) measures strain therein.

Description

technical field [0001] The present invention relates to a load cell used to transmit and measure linear forces along three orthogonal axes and moments around three orthogonal axes. More specifically, it discloses a load cell with a rigid central hub, a A concentrated load cell body with a rigid ring concentric to the hub and radial members extending between the central hub and the ring, the load cell body has improved performance and characteristics to allow easy adjustment of the sensitivity of the load cell. Background technique [0002] Transducers or load cells to determine forces along three orthogonal axes or moments about three orthogonal axes are known. Two such load cells are disclosed in US Patent Nos. 4,640,138 and 4,821,582. A multi-axis load sensitive transducer is set forth in US Patent No. 4,640,138 having inner and outer parts connected by a pair of axially spaced crossheads. The crosshead consists of arms integral with the inner part and connected to the o...
