Attachment part of a driven tool

Abstract

Attachment part of a driven tool (10) for a driven tool, comprising: - an elongated housing (11, 12) with an upper housing part (11) and a lower housing part (12) connected to the upper housing part (11), - an input gear (22) for connection to an output shaft of a driven tool, the input gear being arranged at a first end of the housing, - an output gear (23) having an output connection (23a), the output gear being arranged at a second end of the housing, - at least one intermediate gear (24, 25, 26) arranged within the housing (11, 12) to transmit the rotation of the input gear (22) to the output gear (23), and - two torque sensors (13a, 13b, 13, 13c, 13d, 13e, 13f) configured to measure a deformation of the elongated housing (11, 12), wherein the torque sensors (13a, 13b, 13, 13c, 13d, 13e, 13f) are recessed into the surface of the elongated housing (11, 12) or arranged integrally in the material of the elongated housing (11, 12); wherein the torque sensors (13a, 13b, 13, 13c, 13d, 13e, 13f) are arranged adjacent to an end face of the at least one intermediate gear (24, 25, 26) which is arranged next to the output gear, wherein the housing parts (11, 12) only have holes for fastening the axes of rotation of the gears (22, 23, 24, 25, 26) and for receiving fastening means (21).
