Abstract
The invention relates to a method and an apparatus for measuring the torque passed through a rotatable machine element, in which two parts connected to this machine element rotate relative to one another. This relative rotation is translated into an amplified axial movement, and the axial movement is measured as a standard for the transmitted torque.
Claims9
An apparatus for measuring the torque of a rotatable machine element, by means of first and second elements connected at an axial and/or radial distance with said machine element which rotate relative to one another when a torque is applied to the machine element, wherein a relative rotation between said first and second elements, taking place in a circumferential direction, is translated by means of a plurality of forked elastic levers connected thereto and distributed over a facial surface thereof into an amplified axial motion of a control member, and this axial motion is measured as a standard for the transmission torque, said forked elastic levers are connected at their forked end base portions with one or the other of said facial surfaces of said first and second elements which rotate relative to one another and at their joined end head portions to said control member, in which each of said forked elastic levers (155) are in the form of a fork including two tines (155a, 155b) which extend parallel to one another, each of said tines include apertures in their ends by which said ends are connected to one or the other said elements (52b, 53), one of said two tines (155a) is provided with a reduced cross section (155c) that is yielding in the radial direction and connected on an end with the part (52b) associated with said tine, and said tines (155a, 155b) are joined to one another and form a fork handle parallel with said tines, said fork handle in turn is connected via a thin elastic joint (155d) and a head portion with said control member (59).
