Improvements in dynamometers.

摘要

A transducer head for a moving surface dynamometer comprises a casing (34) having connections for eventual attachment to an extremity of a support arm on a sliding carriage of a loading head of the eventual dynamometer. An axle housing (50) in the casing (34) supports an axle of an eventual test subject (10) to be spun in rolling contact with the moving surface. A multiplicity of strain transducer links (1-6) are connected in load-transmitting relationship between the axle housing (50) and the casing (34) for supplying signals indicating tensile or compressive load therein. There are six such links in a defined pattern. Each link is advantageously threadedly attached to the axle housing (50) and has at its outer end a male tapered threaded region (63) that registers with a straight threaded bore (67) in a cap (65) attached to the casing (34), a tapered sleeve (69) having external and internal threads of the same pitch being tightenable to connect the outer end of the link to the cap and thence to the housing without correspondingly straining the link.
