Problems solved by technology

[0014] The problem with all three aspects (tightening device, drive torque generating device and tightening system) can be seen in the fact that the effect of degraded efficiency has a direct impact on the motor behavior and constant operating behavior, thereby preventing or A defined fastening of screw fittings is not possible
Especially when using an open gear offset head, a brief lapse of the breakout torque due to the output torque caused by the partial support phase can lead to an early disconnection of the motor and thus to tightening in an undefined manner or to an incomplete screw connection

Embodiment Construction

[0072] figure 1 (system view and at the same time contextual view of the invention) shows a perspective view of a hand-held tightening system with a tightening device 2 for applying torque to a screw fitting (not shown), the tightening device 2 comprising The gear offset head arrangement 6 in the housing 4 of the open gear offset head 32 . The gear offset head arrangement 6 is configured at one end (on the output side) to interact with and drive an assembly tightening tool realized as a slotted output gear 8 . On the drive side, i.e. at the end of the gear offset head device 6 opposite to the output, the gear offset head device 6 is connected via an angle head 10 with a pair of gears or bevel gears, if applicable, via a mechanical interface 46 to a A manually actuated drive torque generating device is realized as a tightening tool 12 .

[0073] The tightening tool 12 has a drive motor 26 (eg, electric or pneumatic) and applies an output torque generated thereby to the tighte...

Abstract

The invention relates to a screwing device for applying and / or transmitting a torque to a screw partner and for interacting with a drive torque generating means, comprising flat output means (6) whichhave an output that can be detachably connected to the screw partner and a drive, to which a drive torque can be manually or mechanically applied, an output gearwheel (8) that can be driven by the flat output means (6), a mechanical interface (46) for selective direct or indirect connection to the drive torque generating means for initiating the torque, a compensation unit (30) which is designedto store and process compensation data and which comprises an output gearwheel-specific torque curve and / or an output gearwheel-specific efficiency curve for calculating it with a value of an actual output torque in order to generate a value of a compensated output torque, and a data interface (36) which is designed to transmit compensation data to a drive torque generating means.

Description

technical field [0001] The invention relates to a tightening device for applying torque to screw fittings. In addition, the invention relates to a drive torque generating device for generating torque. Furthermore, the invention relates to a tightening system comprising at least a tightening device and a driving torque generating device. The invention also relates to a method for controlling a drive motor of a screwing system. Furthermore, the invention relates to the use of a tightening system for carrying out the method. Background technique [0002] From practice, especially in industrial tightening technology, such tightening devices are known, which are known as so-called geared offset heads and are used in particular in tightening and assembly work, wherein, due to the specific space Mounting conditions, screw fittings (ie, for example, screws on which torque is to be applied within the context of the present invention) are difficult to reach. Gear offset heads are ...
