Problems solved by technology

However, due to the structure or geometry of the planar drive there are additional, costly problems
Since typical flat drives of the general type are designed to have the smallest possible and compact design at the maximum transmissible torque (which is the intended application for this type of flat drive), the corresponding integration of conventional measuring axes torsion axes is difficult or even impossible

Embodiment Construction

[0025] figure 1 A screwing device for applying torque to a pair of screws according to a first embodiment of the invention is shown in perspective view, having a flat output device 10 accommodated in a housing 30, 32, one end (output side ) to drive a suitable screwing tool 14 in cooperation with the screw 12 as a pair of screws (not belonging to the invention). On the drive side, ie at the opposite end from the output of the flat output device, they pass through a goniometer head 16 with a pair of bevel gears and a manually operable screwing tool 18 as a commercially available Tools, and tools supplied by various tool manufacturers, will be input via a motor (e.g. electric or pneumatic), deflected at right angles via an assembly 16, into a flat output device 10, which in the manner described below will This drive is transmitted to the tool 28 for the screwing operation of the connecting element 12 .

[0026] In particular, refer to Figure 2 to Figure 4 A side view and a l...

Abstract

The invention relates to a screw device for applying torque to a screw partner (12), comprising flat output means (10) provided with an output member that can be detachably connected to the screw partner and a drive to which a drive torque can be manually or mechanically applied, particularly by means of an interconnected angular and / or bevel gear (16), and means (48) for detecting an output torque acting on the screw partner on the output side, the detection means asociated with the flat output means and particularly provided on and / or in a housing (30, 32) of the flat output means being designed such that they can detect an axial force acting on a helical gear (38) connecting the drive and the output member of the flat output means in a torque-transmitting manner and provide same for preferably electronic signal evaluation.

Description

technical field [0001] The invention relates to a screwing device for applying a torque to a screw pair according to the preamble of claim 1 . The invention furthermore relates to a hand-held screwing system having a screwing device according to the invention. Background technique [0002] Screwing devices of the above-mentioned type are known from the prior art, in particular from industrial screw driving technology. Especially in screwing or assembly work, where screw pairs (ie screws to be torqued in the context of the invention) are difficult to realize due to special spatial installation conditions, so-called flat outputs are often used. It is usually a transmission unit housed in a planar housing, usually having a drive arranged at one end and an output arranged at the opposite end, on which a pair of screws can be detachably mounted in a suitable manner. The transmission in the flat output housing here usually consists of an arrangement of gears which mesh with each...
