Force-transmitting element for force-measuring instruments, in particular for electromechanical scales

摘要

The invention relates to a force-transmitting element for force-measuring instruments, in particular for electromechanical scales. The aim of the invention is to use a force-transmitting element in order to transmit a compressive or tensile force from a lever onto a force sensor with improved technical properties. The compressive or tensile force to be measured is intended to be led in a manner free from interfering force and without elastic elements into the measuring body of a force sensor. The aim is to construct the force-transmitting element in an adjustable articulated fashion and free from play above and below, and to guarantee a tolerance-free spacing between the fulcrum of the transmitting lever and the measurement axis of the force sensor. The essence of the invention is that when a compressive force is to be measured the force-transmitting element consists of a rod-shaped coupling element which contains on the upper part a spherical tip, which engages in a ball cup (socket) incorporated on the underside of the transmission lever, and has on the lower part a ball cup which is supported on a spherical tip located on the upper side of the force sensor. The spherical tip or ball cup can be adjusted. When a tensile force is to be measured, the force-transmitting element consists of a frame-shaped coupling element. <IMAGE>
